Chapter 333 12-horsepower single-cylinder diesel engine!

Yanyu Highway is one of the main arteries of the base area. Although it can meet the conditions for traffic, the road condition is not ideal. The land base is mainly mud, and a small part of the road is gravel. The road is full of potholes, which made his back hurt.

When the road projects of Yushen Highway and New Yanma Highway are completed, the construction of Yanyu Highway has to be put on the agenda.

Lu Junyu asked: "Sir, should we go back to the headquarters first, or go to Liushugou?"

"Go to Liushugou Machinery Manufacturing Factory first, and see how the 12-horsepower single-cylinder diesel engine is doing." Yu Hua said, there is only one core technology of the Red Star tractor project, and that is the powertrain - the 12-horsepower single-cylinder diesel engine.

The design plan of the 12-horsepower single-cylinder diesel engine was finalized and confirmed by Yu Hua and Professor Zhuang Qianding at the beginning. According to the plan, it is currently in the stage of prototype trial production.

As long as the powertrain is done, the entire Red Star tractor project will be half successful. After all, this is the part with the highest technical content. Substructures such as the transmission system, cargo box, brake clutch, suspension, etc. all use mechanical parts, and there is no technology at all. content.

Speeding on the two-lane Xinyan-Ma Highway, more than [-] minutes later, the entire Dodge truck arrived at Liushugou, entered the industrial area, and finally stopped firmly in front of the new machinery manufacturing plant that relied on the arsenal.

Get out of the car and stand still.

The factory building with red brick and cement structure came into view, with a height of two floors. Two Red Army soldiers with live ammunition stood at the door, and the plaque of Yancheng Machinery Manufacturing Factory was hung next to it. The familiar diesel generator set came from the generator room not far away. Working sound, continuous and stable power supply to the whole plant.

This is the heart of Liushugou today - the machinery manufacturing plant.

In terms of status and importance, the newly built machinery manufacturing plant has already ranked first in the Liushugou Industrial Zone, even the arsenal next door cannot compare.

As for the reason, it is very simple. Basically all the weapons and equipment parts in Liushugou have to be processed by the machinery factory.

Nowadays, in order to protect the extremely precious mechanical processing equipment of the machinery manufacturing factory from being destroyed by spies, not only a regiment of troops is stationed outside the machinery manufacturing area, but also an exclusive armed security office is set up in the factory area, and a platoon of troops is deployed to strengthen protection.

This is a serious defense with heavy troops.

Through the gate, Yu Hua found that the factory was basically in the state of ten steps, one post and five steps, one sentry. He nodded in satisfaction, and then stepped forward. After being verified by two sentries, he entered the factory area and went to the workshop.

The interior of the factory is divided into mechanical processing area, finished product area, raw material area, warehouse and office area according to the purpose. Passing through the raw material area where various parts and raw materials are piled up, Yu Hua comes to the noisy mechanical processing area and observes quietly like a bystander. The sound of each machine tool running for metal processing complements each other.

The fierce friction between metal and metal plays an industrial symphony unique to Yancheng. One part belongs to the world's top mechanical processing equipment, and the other comes from the high-quality steel produced by the epoch-making oxygen top-blown converter, which is melodious and beautiful.

The turning workshop was in a busy state, and five lathe workers performed their respective duties, processing mortar barrels in an orderly manner, and there were seven or eight standard barrels that had been processed on the ground.

After watching for a while, Yu Hua didn't make a sound, and walked forward to the milling workshop.

At this time, the figure of Professor Zhuang appeared in sight, standing in front of the GROB semi-automatic gantry milling console. Zhuang Qianding controlled the high-speed milling head to come into contact with the cylinder of the prototype machine, and silky metal debris kept coming out. Out, the cylinder block of the prototype has been formed.

Seeing this, Yu Hua quietly entered the workshop, just like in the engineering laboratory of Tsinghua Park, standing quietly by the side, quietly observing and studying.

External milling, point hole, drilling, cylinder fine boring, plus measurement and correction again and again... There is no doubt that the entire milling process is extremely cumbersome.

Time passed, about an hour later, the semi-automatic gantry milling sound disappeared, and the prototype cylinder on the workbench was silvery white, exuding metallic luster, with extremely low surface roughness, revealing unparalleled mechanical beauty like a work of art.

The prototype cylinder block is manufactured!
"Huh... get ready for the engine assembly right away, and try to complete the prototype assembly within today." Zhuang Qianding, who was exhausted, turned off the semi-automatic gantry mill, wiped the sweat from his forehead, adjusted his breathing, and gave orders to the five milling workers. instruction.

Important components such as the crankshaft, crank connecting rod, piston and cylinder head of the diesel engine have been processed, and the cylinder block, which is the last part, has been processed, and the prototype assembly stage has come.

In the past few days, in order to build a prototype as soon as possible, Zhuang Qianding has hardly had any rest, and his body and spirit have reached their limit.

"Yes!" The five members of the milling team nodded in unison, immediately got busy, and carefully left the workshop with the cylinder weighing tens of kilograms.

Zhuang Qianding was a little tired, and was about to sit down and rest, when suddenly, out of the corner of his eye, he caught sight of Yu Hua who was standing on the right side, and was stunned for a moment, with a look of surprise on his face: "Why are you back, kid? Wait, could it be that... "

"Professor, I have some good news for you. The trial production has been successfully passed. This is the trial production report."

With a respectful look on his face, Yu Hua took a step forward to inform the situation, then took out the trial production report and handed it to Zhuang Qianding, and said softly: "We succeeded."

It was successful, yes, it took more than half a year, from the initial conception and planning to the completion of the 24-hour trial production of the test furnace, and finally succeeded.

"The actual output of steel in 24 hours is 94.65 tons, the average output of a single furnace is 2.01 tons, and the output per hour is 3.94 tons, which is 98.5% of the designed output... Good, good, very good, I didn't expect that one day we in China will really develop a product that is better than the West. Every country needs advanced iron and steel smelting technology, Yu Hua, you are now qualified to call yourself the father of the oxygen top-blown converter." Zhuang Qianding was moved by the words, and quickly took the paper report, and when the content of the report came into view, he followed suit. He became excited, his words trembled slightly, and his inner emotions gushed out like a bank burst, and he called out three times in succession.

The father of the oxygen top-blown converter!

In terms of Yu Hua's technical contributions, he is fully worthy of this title. No one in the world is more qualified than Yu Hua to be worthy of this honor, even Besmart, who first proposed the idea of ​​oxygen steelmaking.

Besmart only proposed the idea of ​​oxygen steelmaking, but it is almost unimaginable how difficult it is to turn oxygen steelmaking from a pioneering idea into reality and complete the first industrial application.

Look at how terrible the technology of oxygen top-blown converter steelmaking is?
The actual 24-hour steel output is as high as 95.65 tons!
This is a converter with a smelting quality of only 2 tons!

How big is the gap between a 2-ton converter and an open hearth furnace with hundreds of tons?
A gap of dozens or even hundreds of times.

It has to be said that Yu Hua handed over an unprecedented answer sheet.

Surpassing Britain and the United States, leading the world, and doing so quietly.

"Professor, these are equivalent to false names to me. They are not important. If they are exposed, China will be plunged into a catastrophe." Yu Hua smiled, with a natural expression, and said, "Professor, before I have no ability to protect myself, I will We are not going to publish any papers and news about oxygen top-blown converter technology.”

Although the oxygen top-blown converter steelmaking process is good, it is not something China can afford today.

Once the news is leaked, it will definitely trigger an unprecedented crisis, and almost all industrial countries in the world will put pressure on it, including the Soviet Union, which is regarded as the big brother.

A steelmaking process concept proposed by Besmart 150 years ago, and a cutting-edge metallurgical technology that has completed its first industrial application are not the same concept at all.

Those tigers, leopards and wolves will use all means to grab it, all means in the true sense!
The so-called father of the oxygen top-blown converter is just a false name. Although Yu Hua needs fame to increase his authority, he will not be stupid in this matter.

"Okay, I get it, but you have to understand that if someone develops the oxygen top-blown converter technology ahead of you, then this honor will be lost." Zhuang Qianding immediately understood the meaning of Yu Hua's words, and took a deep breath In one breath, with a solemn and solemn face, he silently regards the oxygen blowing furnace technology as the top secret in his heart, and never mentions it to anyone on any occasion.

Academics have no boundaries, but technology has boundaries.

This top-level technology, which is enough to determine the fate of the country, of course cannot fall into the hands of the Japanese invaders and the West, but here comes the problem. If Yu Hua does not announce it now, if someone publishes the registered patent, the honor of the father of the oxygen top-blown converter will no longer belong to Yu Hua.

This has always been the case in academia, and only the publication of research and development results and registered patents are the real winners.

"It does not matter."

Yu Hua nodded, changed the topic, and was concerned about the Red Star tractor project: "Professor, how is the situation of the single-cylinder diesel engine? At present, the problem of transportation capacity has become our biggest shortcoming. Whether it is road construction or industrial raw material demand, all are limited. Regarding capacity, Yulin Iron and Steel Works has a daily capacity quota of [-] tons, which is only enough to meet the needs of five tons of steel smelting."

"You came just in time. All parts of the first prototype of the 12-horsepower single-cylinder diesel engine have been processed and are in the assembly stage. I just need people here." Zhuang Qianding said with a smile.

"The student understands." Yu Hua smiled.

Zhuang Qianding and Yu Hua turned around and left the milling workshop, and went to the finished product area, where the 12-horsepower single-cylinder diesel engine prototype was assembled.

In the finished product area, the prototype cylinder block, which was like a work of art, is placed in the center of the assembly table, and a series of engine parts are arranged vaguely and orderly on the left and right sides, such as crankshaft, piston, cylinder head and so on.

"Did you forget the design drawings of the engine?"

Standing in front of the workbench, Zhuang Qianding picked up a cast iron wrench and handed it to Yu Hua, saying, "You design the engine, you assemble it."

"Of course not."

Hearing these words, Yu Hua, who is the designer of the 12-horsepower single-cylinder diesel engine, smiled slightly, took the cast iron wrench, and began to work with ease, assembling the engine parts in sequence.

Crankshaft, timing gear, piston connecting rod group, cylinder head, oil pump, water tank, fuel tank, plus the most classic large flywheel.

In more than 20 minutes, with the nuts tightened at the last moment, the power core of the classic walking tractor that later generations shuttled through the streets and alleys and fields—the 12-horsepower single-cylinder diesel engine—was born.
