my scientific age

Chapter 308 Mid-month production!
He came to Liushugou this time mainly to solve the problem of seamless steel pipes for the mortar project of the arsenal. He originally planned to build a skew rolling mill, and the idea proposed by Yu Hua coincided with him.

"Yes, yes...Professor Zhuang, I will take you there, please come with me." Zhao Shu immediately reacted, realizing what it meant at the moment, the whole person was a little incoherent, showing excitement, and answered quickly.

Not only Zhao Shu, but the section chiefs Hu Zhigang and Zhao Zhangcheng were equally excited. After all, the two-stick skew rolling mill was built to produce mortars.

But this is not the point.

The important thing is that they can make their own two-roller skew rolling mill, which is the core equipment for producing seamless steel pipes!

At this stage, there is no need to go to the arsenal for the time being. The group quickly rushed to the sand turning workshop of the iron factory. Next, Zhuang Qianding and Yu Hua quickly constructed the design drawings of the two-roll skew rolling mill, and initially determined the size and shape of the roll and mandrel. .

Mandrel diameter 60 millimeters, length 1 meter, cylinder, theoretical weight 21 kilograms.

The roll has a diameter of 180 mm, a length of 1 meter, a cylinder, and a theoretical weight of 190 kg.

This is a two-roller skew rolling mill with a net weight of about [-] kilograms. It has no flat casing, no electronic equipment, no various precision measuring instruments and control systems. It only has a mechanical structure composed of two rolls and mandrels, which is extremely simple.

The whole two-roller skew rolling mill is driven by a high-power DC motor, and the torque is amplified by the transmission system, and the maximum rolling force is applied to 300KN.

After finalizing the design plan, Zhuang Qianding rushed to the arsenal, accompanied by Hu Zhigang and Zhao Zhangcheng, the chief of the arsenal, and prepared to use the general car of the arsenal to open the mold.

Yu Hua stayed on the side of the iron factory and witnessed the official opening of the first blast furnace in the Shaanxi-Gansu-Ningxia border area.

……

At the feed inlets on the left and right sides of the blast furnace, escalators were built. The former factory director, Martin Martin, and a Red Army soldier carried full wooden barrels. One wooden barrel contained sintered iron ore the size of glass beads, and the other It is coke, which is poured into a funnel-shaped feed port in an orderly manner.

The feed inlet is steaming hot, and the fine coal powder and diesel fuel are violently burned, and then under the action of the blower, a steady stream of heat is released to ignite the coke and sinter.

One barrel after another, the factory manager Martin and the soldiers poured barrels of raw materials into the blast furnace like tireless machines.

If nothing else, the conveyor belt has to be tapped out immediately. ——Yu Hua watched the blast furnace charging process, the factory manager Martin and the soldiers on the escalator were exhausted and sighed softly.

The entire manual loading process is slow and laborious, and extremely inefficient.

Two tons of pig iron, according to the smelting level of the native blast furnace, requires at least four and a half tons of sinter and one ton of coke. These smelting raw materials are all put into the blast furnace by manpower. How long does it take?
"What's wrong?" Lin Wan, who noticed Yu Hua's strangeness and recorded information with a notebook and pencil, turned her head and asked with concern.

"We should manufacture conveyor belt equipment as soon as possible, otherwise, manpower alone will not be able to do great things." Yu Hua said softly, staring at the sweaty factory director Martin and the Red Army soldiers.

He admired Martin, the factory manager who took the lead in personally loading materials, but in terms of the efficiency and time of manual loading, it was far less than the power of machinery.

Conveyor belts, a kind of mechanical equipment for the systematic and highly automated conveying of materials, don’t look ordinary, it doesn’t seem to be a big deal. In fact, this is one of the greatest inventions in the history of human civilization. The reason why modern industry can be so developed, Conveyor belt equipment takes at least one-third of the credit.

Ultra-high conveying efficiency, extremely simple principle structure, single-handedly conveying materials, conveyor belt equipment can completely lift trains, ships and other means of transportation.

"Indeed, manual loading is time-consuming and laborious, but I don't know much about conveyor belt equipment. For the time being, I can only help you with practice and learning." Lin Wan nodded when she heard these words, expressing her support. She knew about conveyor belt equipment. It is important, but due to his academic level and knowledge reserve, he does not know much about the mechanical structure and principle of the conveyor belt, so he cannot share the research and development work for Yu Hua.

Of course, it's no problem to fight and help, anyway, she is also a top student admitted to Peking University.

"It's enough to fight, come on, Jinyu." Yu Hua smiled slightly and stretched out his right hand.

"Come on, Yu Hua."

Lin Wan nodded with a smile and raised her right hand.

"Clap!" The two right hands slapped each other, expressing the most sincere wishes.

The blast furnace charging continued, and after an hour, the factory director Martin and the Red Army soldiers reached their physiological limit and had to be replaced to continue the charging of raw materials.

A total of [-] kilograms of iron ore and coke took two hours.

After all the raw materials are loaded, the feeding port is closed.

The high-power blower arranged under the blast furnace runs at full capacity, and the coke as the main heat source burns violently, releasing a high amount of heat, so that the internal temperature of the blast furnace rises rapidly to about 450 degrees Celsius, and the iron ore that is already in a softened state reacts with limestone The bottom gradually melts to form orange-red molten iron, and a layer of liquid slag gradually floats on the surface.

The whole reaction process inside the blast furnace is very complicated.

Over time, more and more iron ore melted into molten iron, forming a molten pool below the blast furnace.

Outside the blast furnace, harmful waste gas containing various substances continued to emerge from the top exhaust vents, drifting to the blue sky, polluting the surrounding air. Yu Hua, who was standing at a safe distance, smelled the smell from the iron and steel industry. Refreshing.

This taste is right.

When the smelting process was one third of the way, guard Xiao Li and two soldiers rushed over, carrying the ferrosilicon inoculant that had just been smelted.

Immediately afterwards, the figures of Professor Zhuang and his group also appeared one after another. Hu Zhigang was holding the standard cylindrical die for the roll, and Zhao Zhangcheng was holding the standard die of [-]mm mandrel like a gun barrel.

The mold and ferrosilicon are in place and everything is ready.

The skilled workers in the sand-turning workshop of the iron factory make sand molds for rolls and mandrels at the fastest speed. These skilled workers are all from the arsenal workers before the Long March. They have worked in major factories in the Republic of China before, and they are skilled and experienced.

Although they don't know any mechanical principles and mathematical calculations, they have very rich experience in front-line practice. They are familiar with sand-turning and pouring molds. If they are left in Japan, they will be a sand-turning fairy.

Before the first blast furnace in Liushugou Iron Works produced molten iron, the sand molds for four rolls and two [-]mm mandrels were successfully completed and transported to the blast furnace to wait for molten iron.

Time passed by, and the crowd around the blast furnace of the iron factory became more and more. Chen Kang, the highest technology team, the heads of various departments of the Military Industry Bureau, the heads of major factories, and General Liu who heard the news, etc. People, the battle is not too big.

This is the first furnace of molten iron in the base area, which is of great significance, and everyone is just witnessing it.

At 10:30 in the middle of the night, it was time to officially tap the molten iron.

Below the blast furnace, four workers carried a crucible that could hold 150 kilograms of molten iron like a sedan chair to the tap hole and waited, followed by three groups of such teams.

At this moment, the audience is watching.

When the first group of foundry teams was ready, an old worker came to the tap hole below the blast furnace and used a steel drill to open the mud seal. In a flash, the magma-like orange-red molten iron suddenly poured out and entered everyone's line of sight. The trench flows into the crucible below.

"Papapa!" Seeing the orange-red molten iron flowing into the crucible, everyone at the scene applauded one after another.

There is no doubt that this is a historic moment, symbolizing the restoration of pig iron production capacity in the base area again.

Not long after, the first pot of molten iron was filled. Four casters carefully carried the 150-kilogram molten iron away from the blast furnace and headed for the pouring area.

Coming to the pouring area, the first group of casters picked out the slag floating on the surface, and then the factory manager Martin, who was standing by the side, threw a portion of powdered ferrosilicon into the molten iron in the crucible according to the pre-arrangement, for inoculation treatment, manufacturing artificial nuclei.

This is the standard ratio that was accurately calculated by Yu Hua. Although Martin did not know why he put in ferrosilicon, he still carried out the order.

After stirring, in the microscopic world, the high-temperature molten iron reacts under the action of ferrosilicon, producing fine artificial crystal nuclei and precipitating graphite.

After adding the inoculant, the factory director Martin retreated to a safe distance. The first group of four casters tilted the crucible nozzle, aimed at the water inlet of the mandrel sand mold, and poured out the molten iron.

"Squeak!" The fiery red molten iron was like a faucet, continuously flowing into the mandrel sand mold. In an instant, the sand mold made a sound like frying, and flames erupted inside.

Fortunately, no explosions occurred.

The first mandrel sand mold was poured, and then the second mandrel was poured. The two mandrels were not heavy, adding up to more than 40 kilograms. The remaining [-] kilograms of molten iron in the first pot was used to pour the roll sand mold.

The four roller sand molds belong to the large demand for molten iron, requiring a total of more than 800 kilograms of molten iron.

Under the watchful eyes of all, four groups of casters reciprocated, pouring hot molten iron with ferrosilicon into the roll sand mold.

After more than [-] minutes, all the roll sand molds are poured, and the next step is the most important cooling and solidification stage of smelting gray cast iron.

To obtain gray cast iron, one is the inoculant, and the other is the cooling time. The temperature in the cooling and solidification stage cannot drop too fast, otherwise the graphite cannot be precipitated.

If necessary, the casting needs to be taken out of the sand mold and placed in a hot sand pit with a temperature above 500 degrees Celsius, or slowly cooled in a near-hot furnace.

Yu Hua and Lin Wan entered the pouring area, surrounded the six sand molds, and carefully recorded data such as pouring time and pouring performance.

"The cooling time of the mandrel is one and a half hours, and the cooling time of the roll is five and a half hours. After this time, the mold can be demolded. Jin Yu, you can record it." Formula to calculate the approximate cooling time.

"Okay." Lin Wan nodded, holding a pencil in her right hand and writing down the cooling time data in the notebook.

Compared with the accumulated subjective experience of workers, smelting gray cast iron requires more systematic statistics and analysis to obtain corresponding metallurgical data.

"Deputy Team Leader Yu, how long does it take for the grenade casing to cool down?" At this time, Zhao Shu, the public works section chief, who was watching, asked aloud, "The arsenal is preparing to pour the grenade casing."

"Senior Zhao, the shell of the grenade can be demolded in 15 minutes. After it cools down to room temperature, gray cast iron can be obtained." Yu Hua replied with a smile, "Remember to add ferrosilicon."

15 minutes……

Zhao Shu nodded and turned to leave.

Soon, four casters started pouring grenade shells. In addition to the six sand molds in the pouring area, a thousand sand molds for grenade shells prepared in advance had been placed, divided into ten batches. Batch of one hundred grenades.

Under the shroud of night, the casting operation of the iron factory began again. Unlike the previous casting machine parts, this time it was a military production.

The grenade shell sand molds were filled with hot and fiery molten iron, and in a flash, these sand molds were lit like candles, emitting orange-red flames.

The caster team is responsible for pouring molten iron. Zhao Shu and Hu Zhigang, who are technical cadres, recorded the pouring time of each batch of grenade shell sand molds according to Yu Hua's method, and then marked the predetermined cooling time.

The first batch.

Second batch.

Fifth batch.

Eighth batch...

The molten iron lamps are lit up, releasing gorgeous and dazzling flames. The picture looks as beautiful as a lantern festival. It contains the atmosphere of the Yancheng era in 1937, which is picturesque.

"It's really beautiful." Yu Hua looked at this picture and smiled. This kind of unique beauty of the industrial version 0.1 is rare.

Lin Wan, who was beside her, nodded lightly, with a faint smile on her face, looked at the sand mold with flames on the ground, and then turned to look at Yu Hua.

"Professor, the sand molds for the mandrels and rolls are basically poured. You can take them out after the cooling time. I'm going to design the conveyor belt before I leave to improve the efficiency of raw material transportation." Yu Hua looked at Zhuang Qianding next to him and said.

According to the schedule, Yu Hua will leave early tomorrow morning to go to Yulin to inspect the specific site of the iron and steel plant, and there is not much time left.

Nowadays, it is only a matter of time before the successful smelting of gray cast iron. The [-]mm mortar project of the Arsenal is solved by a two-bar skew rolling mill. Yu Hua is ready to point out the conveyor belt equipment before leaving.

"Okay, choose the belt type, or the bucket type?" Zhuang Qianding nodded, supporting Yu Hua's idea, and asked.

The belt conveyor mainly consists of a belt to form the conveying carrier, and the bucket conveyor, as the name suggests, consists of a metal hopper to form the conveying carrier. Both types are the current mainstream conveyor belt equipment.

"I think the belt type is better, the cost is low, the technical requirements are not high, and the bucket type is more expensive."

Yu Hua gave his own thoughts: "After all, sometimes, being expensive is the original sin."

"Little boy, you can talk in different ways, classmate Lin, you stay here to help, and Yu Hua and I will go to the office." Zhuang Qianding shook his head with a smile, and arranged it immediately.

"Okay, professor." Lin Wan nodded.

Afterwards, Zhuang Qianding and Yu Hua left the blast furnace area of ​​the iron factory and went to the iron factory office not far away. On the way, they kept discussing the technical details of the belt conveyor.

No conveyor?

Then make it directly.

Anyway, there is a blast furnace, and the arsenal also has a high-power DC motor for a general car and an oxygen top-blowing converter project, and the materials are well-equipped.

……

Time passed by minute by minute.

Not long after, 15 minutes passed, and the first batch of grenade shells arrived at the demoulding time.

At this time, the pouring operation of Liushugou Iron Works was still going on. There was no other way. There was still a whole ton of molten iron in the blast furnace, which was enough to cast more than 5000 grenade shells.

As the leaders of the two major departments of the Military Industry Bureau, Zhao Shu and Hu Zhigang have already come to the pouring area, standing next to the first batch of grenade sand molds, holding torches, waiting for the most important smelting results.

Whether white iron or gray iron is smelted is extremely important.

The shell demoulding work was carried out by the factory manager Martin. He seemed a little nervous, took a deep breath, and then opened the upper part of the grenade sand mold under the watchful eyes of the two.

Immediately afterwards, a cloud of black quartz sand with blue smoke and high temperature appeared. Martin held iron tongs to remove the quartz sand on the surface, and then took out a familiar metal casting from it.

Cylinder, hollow, engraved with diamond-shaped fragment grooves, rough and dark red on the outside, and most importantly, the whole body is dark.

"Chief, we seem to have succeeded. This is not the white iron smelted in the Soviet area before, but gray iron." The torch was close to the shell, and seeing the gray color of the whole body, the experienced Martin was stunned for a moment, and his face suddenly showed joy. With excitement in his eyes, he shouted towards Zhao Shu and the others.

Excited.

Excited from within.

As a worker who used to work in Hanyang Iron Works, the factory manager Martin has rich experience in iron making. He can distinguish the difference between white iron and gray iron. The grenade shell in front of him is not white iron smelted in the Soviet area. But the real gray iron!

"Old Ma, please check again if it is gray iron." Zhao Shu's words showed respect, and he resisted the excitement.

"I will never admit it wrong. This is the gray iron made by the Hanyang Iron Works in the past. The white iron is so hard that it will crack with a light hammer. Look at this grenade shell." Martin nodded again and again and explained briefly. , then hammer the shell with iron pliers.

"Ding!" The gray-colored shell didn't shatter, but made a crisp metal crash sound.

"Haha, it really did." Seeing this, Zhao Shu smiled and couldn't help laughing.

"It's been more than ten years, and gray iron has really been made..." Hu Zhigang, who was standing next to him, was also relieved, and he couldn't help but mention that Zhao Shu was happy.

Don't look at the simple iron smelting, the smelting of gray iron alone has troubled the organization for more than ten years.

The technical difficulty of smelting gray iron and white iron is completely different from the same level. At the time, the Soviet area arsenal organized technical cadres and workers to study the gray iron smelting technology, but it has still failed to succeed today.

And now...

It turned out that a small amount of ferrosilicon was added to the ash-smelting iron, and then it was allowed to cool slowly.

Such a simple smelting technology has stopped everyone for so many years.

Hu Zhigang looked back on the meetings he tried to smelt gray iron over the years, and his emotions were a little complicated, and Yu Hua's smiling face appeared in his mind.

If it wasn't for Yu Hua, they would like to make gray iron, and I don't know how long it would take...

Soon, Zhao Shu will report the news of the successful production of gray iron to Chen Kang.

Chen Kang, who received this news, was instantly overjoyed and his mood was ups and downs. Really, the news of the successful production of gray iron had a greater impact on him than the oxygen top-blown converter technology that Professor Zhuang and Yu Hua had been studying.

After all, the oxygen top-blown converter technology is far away for him, and smelting gray iron is one of the biggest problems faced by the Military Industry Bureau.

"Have you mastered the technique of smelting gray iron?" Chen Kang took a deep breath, forced himself to remain calm, pinched his dry throat, and asked Zhao Shu.

Zhao Shu nodded: "I got it, the secret lies in time and ferrosilicon. Ferrosilicon needs to be smelted with an electric furnace."

"Okay, okay, let the electric furnace steel mill make one furnace of ferrosilicon every day to supply the blast furnace." Chen Kang became more and more excited, his words trembled slightly, and after thinking about it, he gave the instruction: "Hu Zhigang!"

"Have!"

Hu Zhigang on the right responded immediately.

"Send me all the grenade sand molds from the arsenal immediately, I'm not going to sleep tonight, I will hit the production record!"

Chen Kang, who was extremely excited, directly assigned the production task as the top leader of the Military Industry Bureau, just like the sales at the end of the month: "Also, start the work of casting mortar shells immediately, and give me the actual daily output of shells. Let’s get 300 pieces first, remember the most important point, keep the quality and quantity!”

With gray iron, the 60mm mortar shells that have been stuck in the drawing state can finally start production.

Although the shell production ≠ the actual production of shells, it is always better than zero production.

In addition to that, produce more grenades.

The number of grenade shell sand molds made by the arsenal is not [-], but also [-]. In addition, there are fifty sets of shell steel molds.

In one word - rush production!

Of course, Chen Kang did not pursue high output, and he also had strict requirements on the quality of grenade shells.

The quality of the grenade produced by the Military Industry Bureau must be stable and reliable, which is crucial, because this is the weapon that is to be handed over to the soldiers.

If the quality of the grenade is not good, it will explode immediately after pulling the rope, and the consequences are self-evident.

In the past, it was impossible to make this kind of defective grenade. Now that the technical problem has been solved, we must not make this kind of grenade with serious defects.

Made in the border area, reliable quality!

"Yes!" Hu Zhigang nodded, took the order, and left quickly.

"Sir, we have finally made gray iron." After Hu Zhigang and Zhao Shu left, Chen Kang walked quickly to General Liu, who was watching the pouring operation, and informed him of the news.

"Is this news true?" General Liu was startled and asked seriously.

"It's 100% true. It has been verified many times. With the help of Yu Hua, we have successfully refined gray iron." Chen Kang affirmed: "Next, I plan to produce 60mm mortar shells and try to increase the daily output of shells to 100. Hair, quality and quantity."

Hearing the arrangement given by Chen Kang, the elegant General Liu nodded affirmatively: "It's really not easy... You did a good job, you didn't embarrass me, I'll go back and report the news to the boss first, I will definitely To protect the safety of Professor Zhuang and Yu Hua, this is the highest order from above."

"Yes, I understand! Except for the section chiefs, Comrade Zhao and the security guards, no one else in the Military Industry Bureau currently knows Professor Zhuang's identities and claims to have hired technical experts." Chen Kang replied.

"it is good."

Hearing this arrangement, General Liu nodded, turned around and left without wasting any time.

After General Liu left, Liushugou in the middle of the night fell into an unprecedented lively scene. The whole grenade production could be described as 'in full swing' in the physical sense.

The factory manager, Martin Martin, directed the casters to carry out uninterrupted pouring operations. Zhao Shu arranged for demolders to take out the grenade shell made of gray cast iron. Hu Zhigang stayed in the sand foundry and instructed the sand foundry workers in the iron factory and the arsenal to manufacture new grenade shell sand. molds, and sand molds for 60mm mortar shells.

Hit production!
Hit production!
Hit production!
The soldiers and workers seemed to work tirelessly. In just one hour, the output of gray cast iron grenade shells reached 60, and the output of [-]mm mortar shells reached ten.

Subsequently, the grenade casings and shell casings, which have been naturally completely cooled, are sent to the arsenal for the production of full-body grenades and shells.

……

The next day.

The rising sun brings a new dawn to the Loess Plateau, which had been sleeping all night.

At the entrance of Liushugou, a Dodge truck was ready to go. Security guard Lv Junyu and three soldiers with live ammunition stood beside the car, standing in military posture.

Today is the day that Yu Hua left for Yulin for inspection.

Yu Hua and Chen Kang were basking in the early morning sun, and the two of them walked along the cinder road as if they were friends, heading towards the entrance of Liushugou.

"Did you sleep last night?" Chen Kang yawned and asked with concern.

"I slept for a while, and I drew the drawings of the belt conveyor overnight with the professor. The iron ore and coke feeding ports of the blast furnace are equipped with conveyor belts, which can greatly improve the efficiency of raw material transportation. In addition, I also designed a hand crank Type ball mill, a drum with a lot of iron balls in it, can grind iron ore, save labor, and it is very simple to manufacture.”

Yu Hua was enjoying the morning sun very much, squinting his eyes, showing a comfortable expression: "There is also a two-bar skew rolling mill. When this machine is completed, the arsenal can produce seamless steel pipes, but for the time being, due to the lack of machine tools, I want to make It may be a while before real mortars come out."

Making seamless steel pipes is the first step in the production of mortars, followed by a series of processing.

"I'm not one to say thank you, but I still want to say thank you."

Chen Kang heard the information explained by Yu Hua, and thanked him softly: "The Military Industry Bureau can have this situation, and it is inseparable from your efforts. Thank you for giving us the technology of Yu's Seven Pagodas, and thank you for your help all the time for us. Professor Zhuang is here."

"That's my job."

Yu Hua looked at Chen Kang's bloodshot eyes and responded with a smile, "You didn't sleep last night?"

"I ran the grenade production last night and stayed up all night."

Chen Kang nodded and smiled mysteriously: "Do you want to guess how many grenades were produced by the arsenal last night?"

"If there are grenades... 1000?" Yu Hua heard the words, thoughtfully, pondered for a while, and gave the output data of the psychological estimation.

A grenade and a grenade shell are not the same thing. Yu Hua is still very curious about the current daily output of grenades at the Liushugou Arsenal. According to the scale, it is about a thousand pieces.

"The guesses are close to ten. A total of 1165 grenades were produced last night, which is currently the highest single-day output of grenades in the Military Industry Bureau, and 38 times the single-day output of yesterday."

Chen Kang sighed softly: "I planned to produce [-] grenades per day, but I didn't expect the single-day output to reach the thousand level so quickly, which has already caught up with the level of the general arsenal in the Soviet area."

Planning [-] and actual [-], the impact of the two concepts are completely different.

Yesterday, the single-day output of grenades was 30, hovering in double digits, and today's 1165 grenades directly exceeded the thousand level and soared to four digits.

To be honest, Chen Kang feels a little illusory now, and feels that this output data is unreal. Looking at the past, only the Soviet General Arsenal in its heyday can reach this level.

But the problem is that the Soviet General Arsenal has only a very small amount of time when the daily output of grenades exceeds [-]. Most of the time, it can make hundreds of black powder grenades every day, which reaches a high production level.

"This shows that your work is very effective. Do I remember that you were not in charge of the army before? Why did you transfer to be the director of the military industry?" Yu Hua smiled and asked curiously.

Yu Hua has always been curious about the brigade commander serving as the director of the military industry.

There is no way, according to his understanding of the brigade commander, the brigade commander is still studying at the Anti-Japanese University at this time point. In August, he immediately accepted the reorganization and became the Eighth Route Army. He took office directly and served as the commander of the 386th Brigade.

Today, Chen Kang is the head of the Military Industry Bureau.

The world is amazing.

"You ask me, who do I ask? Before, I didn't know anything about military production, and I learned it little by little every night." Chen Kang shook his head helplessly and looked at Yu Hua: "However, there is something I can tell you. , I should be leaving office soon to go to the army, and Li Qiang will be my successor."

"Li Qiang?" Yu Hua stopped, looking puzzled.

"You may not know him. Li Qiang's original name was Zeng Peihong. He developed the first radio transceiver for the organization. He used to be the head of the Teko Transportation Section. He has a very high talent in the field of radio and is also an excellent genius."

Seeing the doubts on Yu Hua's face, Chen Kang smiled and briefly introduced the confidential information about Li Qiang: "Not long ago, he went to the Soviet Union to study, and also published a paper on "Sending a Letter Rhombus Antenna", it is said that this paper has a very good response Great, he shocked the Soviet communication academia. In terms of people, he has a friendly personality and is easy to get along with, that is, I have nothing in common with him. Same."

Zeng Peihong!
Damn it, Doraemon of the Red Army!
Yu Hua was shocked when he heard Li Qiang's alias and identity information. The name Li Qiang hadn't evoked his memory, but the name Zeng Peihong was too familiar.

Marley is on top. This is a famous top boss in history. In later generations, he was called 'the Doraemon of the Red Army', 'a super genius who is more like a traveler than Wang Mang'.

So the question is, how awesome is this Zeng Peihong?
If Yu Hua remembers correctly, Mr. Zeng Peihong graduated from the Civil Engineering Department of Nanyang Road and Mining College in his early years. He was born in civil engineering. Since the organization needs arms, but they cannot buy them on the market, they can only find Zeng Peihong, indicating that you are studying civil engineering. Study chemistry, develop arms for the organization.

Zeng Peihong didn't say a word, he fiddled with unearthed explosives and grenades, and successfully created the first batch of arms in the organization.

Later, due to the lack of radio equipment in the organization, it was impossible to contact the Soviet Union. In addition, the radio station was in a high degree of control during this period, and it was impossible to obtain it. There was no way but to find Zeng Peihong again, saying that you are studying civil engineering, and rounding up is to major in radio, for research and development for the organization. radio station.

Zeng Peihong immediately turned to the field of research and development of radio, and then showed an extremely amazing talent for radio research. In 1929, he developed the first radio station in the history of the organization.

One person, in 1929, built a radio station, and there is no need to explain how high the gold content is.

In the 30s, Chen Kang said that he went to the Soviet Union to study a few years ago and published an English paper "Send a Letter Rhombus Antenna". Yu Hua didn't know how awesome the content of this paper was. The paper was so good that the Soviet Academy of Communication Sciences had to directly promote Zeng Peihong, a student, to the seventh radio expert of the Academy of Sciences, and the research result was named 'Li Qiang's Formula'.

You must know that the research level of the Soviet Union's radio communication ranks among the top in the world. As a foreigner, Zeng Peihong directly became the seventh expert of the Soviet Academy of Communications. When Yu Hua read this, he was already shocked.

After the outbreak of the Anti-Japanese War, Zeng Peihong returned to China and presided over the military production and research and development of the base area, greatly improving the level of military production, alone supporting the military production system in the base area, and building a certain basic level of heavy industry.

Gun factories, steel mills, explosives factories, kerosene factories, pharmaceutical factories... These are the achievements of Zeng Peihong, or his brilliance.

If you want a radio, do it right away.

If you want arms, do it right away.

The Anti-Japanese War is coming, and we need guns, explosives, and medicines, so do it right away.

This is why it is called 'Red Army Doraemon'.
