Siheyuan: Starting from a fitter

Chapter 117 The vacuum furnace was successfully developed

Going home in the evening, Aunt Liu and Zhao Ting went home earlier than Li Guocheng.Aunt Liu was busy in the kitchen. Suddenly, the room became bustling, and she felt like she was at home.

"Aunt Liu, happy New Year", Li Guocheng hurriedly said hello to Aunt Liu.

"Xiao Li, happy New Year to you too," Aunt Liu responded while cooking.

Seeing Li Guocheng washing his hands and asking for help, "I don't need your help, everything will be fine, you can call Ting'er for dinner."

"Okay." Li Guocheng didn't show any pretense. He opened the side door, walked through the living room, entered the bedroom, and saw Zhao Ting lying down fully dressed.

"Lazy lady, it's time to get up and eat." Li Guocheng kissed Zhao Ting's sexy lips.

Zhao Ting stretched, sat up slowly, and said coquettishly: "It's not because of you," and then rolled her eyes.

Li Guocheng didn't answer, he just laughed. Looking at the lazy figure who had just gotten up, Li Guocheng couldn't help but leaned forward and put his arms around Zhao Ting's thin waist.

"Don't make trouble, hurry up and eat." Zhao Ting gently pushed Li Guocheng.

Li Guocheng also knew that the time was not right, so he just pecked lightly and said, "Daughter-in-law, you are so beautiful."

Zhao Ting gently stroked the scar on the right side of her face. Although the scar disappeared, there was still a faint mark left, "Okay, Aunt Liu is in a hurry."

At the dinner table, the three of them were eating and chatting, and the meal was soon over.

Apart from giving away the fish in the kitchen, only a few are still hanging.The water tank that serves as the refrigerator also has a lot of food stored in it.Li Guocheng pulled Aunt Liu to show his results, which surprised Aunt Liu.

In the bedroom, after the fierce battle, the two hugged each other, as if this was the only way to feel the warmth.

"Daughter-in-law, will you still be so busy in the future?"

"Probably not." Zhao Ting also felt that she owed Li Guocheng too much.

"Now that a piece of my heart disease has been removed, I won't have to work so hard in the future. You know? It's a kind of hatred that tortures you all the time." Zhao Ting did not hold back anymore. Anyway, Li Guocheng still retained his status as a field worker.

"Old K is a long-term nightmare for our department. No fewer than 10 team members have been injured or killed. Do you remember Sister Wang? After the last injury, she transferred to logistics."

Zhao Ting leaned into Li Guocheng's arms again and continued: "Old K has strong concealment ability, accurate marksmanship, ruthless melee combat, and fast movement. No matter how far or near, he can't aim at all. Every time he catches his tail, he escapes. , someone will fall into his hands every time.”

Perhaps thinking of her comrades, Zhao Ting was very depressed. Fortunately, she didn't cry like other women.

"This time we dispatched three teams. Most of them were equipped with mechanical exoskeletons and bulletproof vests. Of course, we also prepared 3 bulletproof shields. We kept biting him and chased him for more than an hour. At the cost of five people being injured, , and finally captured him, but unfortunately he was not captured alive.”

It turns out that this is what Mr. Yuan was talking about.

"Through the clues on him and our constant monitoring, the next step was the arrest and interrogation, which didn't come to an end until the Spring Festival. Thank you very much this time, otherwise he would have escaped again."

The next day, Li Guocheng came to the laboratory in high spirits. It was a new year and a new atmosphere. As soon as he arrived, he got good news.

"Xiao Li, all the parts of the vacuum furnace have been processed. Everyone in the assembly still believes in you," Gong Wang said with a smile.

"Great", Li Guocheng waited for this day for a long time.

"Zhou Xiaojuan, Tang Danian, how is the equipment you are responsible for?" Li Guocheng shouted to the two of them.

They came over in a hurry.

"Mine has been assembled," Tang Danian said.

"Mine has been tested and it fully meets the requirements." Zhou Xiaojuan has always been reliable.

"It's great." Li Guocheng felt that everything was ready and all he needed was the east wind.

Looking at everyone gathered around, Wu Liankui took the opportunity to express his idea of ​​grouping.

"After I announced something, our laboratory was divided into two groups. One is the semiconductor group, headed by Comrade Li Guocheng; the other is the machine tool group, headed by Comrade Wang Jinggang."

Some people have doubts, but everyone still applauds habitually, which means that the group opinions are passed.

"At present, the semiconductor team only has Comrade Li Guocheng and Comrade Zhou Xiaojuan, and two more people will be added in a few days. We don't have many people in the laboratory, but we have achieved a lot. Next, the factory leaders hope that we will continue to carry forward our style, work hard, and create greater glories."

Some young people and new fitters applauded desperately, and several old people echoed with a smile.

Several old people have achieved results. Wang Gong's thermal stress relief technology has been awarded by the ministry and has been promoted nationwide. The name is 'Wang's Thermal Stress Release Technology'.

Master Yi now masters motor manufacturing and advanced assembly technology, and is now leading three other fitters to study machine tool assembly technology.

Even Zhou Xiaojuan and Tang Danian have independent design results, not to mention the technical leader Li Guocheng.

Now, from the mechanical and electrical department to the factory leaders, they attach great importance to precision laboratories, and the security level is the highest in the steel rolling mill. Although everyone's income cannot be special, the honor is real.

In this era, everyone regards honor as more important than life. You can imagine how high the prestige of the laboratory is among the workers of the steel rolling mill.If it were not for the covert protection measures, Li Guocheng would have become a man of the hour in the steel rolling mill.

Now Wu Liankui is the leading figure in the laboratory. He attends various meetings and receives awards, and has become a man of the hour at the top.There is pressure and gain, which is what he has always pursued. With his background, these pressures can be digested invisible.

Now the exhibition room of the laboratory is the biggest selling point of the steel rolling mill and the biggest talisman of the laboratory.

Everyone in the laboratory is very motivated and smart. After experiencing various activities, they understand that in the end, results must be implemented.I know that as long as I study hard, I will achieve something.Not to mention, they all have the idea of ​​​​contributing more to the development of the country.

Now the first assembly shop has become a semiconductor laboratory.Although they were divided into groups, several old people were concentrated in the laboratory.

At this time, Li Guocheng was installing the vacuum furnace. Everything else was relatively easy. After Li Guocheng checked the processing accuracy, he did not make any corrections and just completed the assembly.

The most complicated thing is the installation of the pull-up handle of the single crystal column, which needs to be able to move up and down, and the pull-head part needs to be able to automatically rotate clockwise with the pull-up action. The technical difficulty is not great, but the difficulty is high assembly accuracy.

Under Li Guocheng's abnormal assembly techniques, the slider part was successfully assembled.

The next step is the direct connection part with the vacuum chamber. When Li Guocheng designed this part, he thought of many solutions, but none of them were ideal.Finally, I got the inspiration while having dinner together.

It is the joint structure of the crab's legs. Li Guocheng imitated the crab joints and designed the connecting parts, which are actually 6 sets of tiles. Each layer of tiles is sealed by a steel ring. The piston movement of the engine is simulated between tiles, which satisfies the sealing requirement. and high temperature protection design requirements.

The entire assembly lasted for 3 days. In the end, both Gong Wang and Master Yi participated in the inspection. After everyone agreed that there was no problem, everyone recommended Li Guocheng to start the equipment.

Li Guocheng did not refuse, and pressed the start button with confidence, and the sound of a blower suddenly filled the entire laboratory.

After 40 minutes, the vacuum degree reached the design requirement of negative 5th power without any accidents.All participants were excited, cheering and applauding.Not to mention semiconductor applications, the vacuum furnace itself is a domestic initiative and can be reported as a separate technical achievement.

The successful research on vacuum furnaces means that Huaxia has made breakthrough progress in vacuum quenching and tempering, vacuum annealing, vacuum solid solution, vacuum sintering, vacuum chemical heat treatment and vacuum coating.

The index of negative 5th power is Li Guocheng's idea. He wants to realize the highest domestic index in the 90s now.Because of insufficient information, he doesn't know what the highest foreign index is now, but he guesses it won't be too high.

In the future, for pulling out semiconductor single crystal pillars, working at the negative third power will meet the requirements. Such design indicators leave a lot of room for subsequent semiconductor design.

The successful development of the vacuum furnace marked that semiconductor research could be put on the agenda. Now Li Guocheng is full of motivation.
