Chapter 20 It’s like a world away
“Master Yi, later I will ask Mr. Liang to tell you about the working environment, installation conditions, installation requirements, etc. of this equipment, the shell, protective tubes, connectors, etc. You and I can discuss the design of the additional parts, and the specific production and processing will be left to you. The material to be processed is a high-temperature resistant material with relatively high hardness, which is similar to stainless steel or may be stainless steel. This is what Master Yi wants. Think about it first.”
Yi Zhonghai nodded confidently, and he could say that he had a handle on this piece of processing.
"Chief Wu, I have trouble with the temporary loan of equipment, space, and personnel in the factory. Yesterday, Mr. Chen had contacted the steel factory, and they agreed to provide support. We have enough nickel powder, please follow up.”
Deputy Section Chief Wu nodded with satisfaction, dealing with people from other departments in the factory is very easy for a veteran middle-level employee like him. Moreover, this matter is both important and hassle-free, which suits him very well.
Gao Zhendong continued to make arrangements: "Chief Wu, after you confirm with the steel mill, please ask Master Yi, what is your apprentice's name?" Gao Zhendong asked knowingly.
Jia Dongxu probably felt this way in his heart: "???Yesterday you were still yelling at Dongxu Dongxu, but now you have turned your back and refused to recognize me?"
Yi Zhonghai was stunned and immediately He reacted with a smile on his face: "Jia Dongxu!"
"Ah, yes, Jia Dongxu." Gao Zhendong emphasized again and said: "Master Jia, please do it before the processing work starts. Please cooperate with Section Chief Wu. Section Chief Wu will grasp and communicate related matters. I would like you to handle the specific procedures and errands first, such as the nickel powder from the steelmaking plant just mentioned.”
Gao Zhendong arranged an errand boy for Section Chief Wu. Section Chief Wu nodded secretly. This young man is still very considerate of his old comrades.
Jia Dongxu quickly agreed.
“If you encounter any problems with the tasks you just received, please report them to Section Chief Wu and me in time and we will solve them.”
Xiao Liu was anxious: “Lao Gao, what about me? What? "In state-owned enterprises, young people of the same generation like to imitate old comrades and call each other "Old X".
"Rong Guo, don't worry, you cooperate with me and we will make electrodes together."
Xiao Liu stupidly said: "Isn't there a Globar furnace burning at Sister Fang's place?"
>
Gao Zhendong smiled: "Sister Fang is testing protective tube materials, and what we are doing here is electrode materials. Except for the nickel powder that has been solved in the steelmaking plant, other materials are mainly solved in the factory. I will give it to you later. A list of materials, you go and confirm the materials, such as chromium powder, silicon powder, etc. If they are not available in the factory, you can come to me again.
"In addition, you can also provide the usage time of Corey's small vacuum induction furnace. To come down, we're going to use it next. I will continue to study material selection and ratio issues here. When your place is ready, we will start trial production of electrodes. "
Xiao Liu felt at ease this time: "Okay, leave it to me. ”
After things were arranged, everyone took their tasks and started working separately.
For the biggest problem of electrode preparation, the method Gao Zhendong planned to use was powder metallurgy.< br>
Simply put, it is to mix an appropriate amount of main material powders such as nickel, chromium, silicon, and auxiliary raw materials such as additives, catalysts, trace elements, etc. After molding, a vacuum induction furnace is used for sintering to obtain the finished product.
The advantage of powder metallurgy is that the sintering temperature is much lower than the melting temperature of the smelting method. Vacuum sintering can also bring benefits to the compatibilization reaction, less gas participation in the reaction, controllable material flow inside and outside the system, and product impurities. With the advantages of less and higher quality, the combination of the two can greatly improve the success rate of electrode preparation.
Of course, in practice, it is not as simple as the above.
It has to be said that a large plant like the third rolling mill is convenient. Vacuum metallurgical equipment that was rare in the country in the 1950s can be used. Gao Zhendong couldn't help but think of a saying he often heard in his previous life: "The platform is very convenient." Important. "
As for the selection and proportion of research materials that Gao Zhendong said, there is actually no such thing. Everything is in his head.
On the contrary, he had to make up several ways to mix materials with poor performance. Otherwise, firstly, the lack of continuity in the research is very suspicious, and secondly, there is no enough comparison to find the best mix. Reliable. R&D continuity is very important. In Gao Zhendong's previous life, his graduate teacher once said to him when he was chatting that many companies were killed for this reason when they applied for high-tech enterprises, and R&D continuity is difficult. Falsification can be seen by real experts at a glance, and many of them are even killed after review.
Everyone was very busy, including Gao Zhendong. His "reverse operation" lasted until the afternoon. From time to time, people from the group came to ask him questions. At noon, I went to the cafeteria to get a meal, and Silly Zhu happened to be at the window, laughing at him for not being energetic.
After work in the afternoon, Gao Zhendong went back to his room, put down his things, washed his face, and went straight to Shazhu's house.
He Yuyu saw him at the door and called him sweetly: "Brother Zhendong, are you here? My brother has been talking about you for a while. Is there any candy? Is there any candy? Give me two."
He Yuyu and Gao Zhendong are also familiar with each other. Gao Zhendong usually smiles and always takes out some food from his pocket when he sees the children in the yard. In addition, Shazhu and Gao Zhendong often interact, so He Yuyu didn't look out when he saw him, he was very affectionate.
In this era, children are not picky about their mouths, and they are not picky about snacks, because they are very lucky to have snacks. If it is candy, it is simply a supreme enjoyment and can make them happy for many times. sky.
Hearing what He Yuyu said, Gao Zhendong took out two sweets from his pocket and handed them to her, and walked into the room.
Si Zhu worked the night shift the first night and went home after noon. Why do cooks have to work night shifts? Because in such a large factory, there are three shifts, and night shift workers also need to eat.
He went home to rest until half an hour before lunch, and then started to work until Gao Zhendong came in.
Jia Dongxu is already at Shazhu's house, helping to carry a plate and a bowl. Taking the letter of introduction and relevant documents from the factory, he went to the steel plant to go through the nickel powder procedures. After finishing all the things that could be done today, it was almost time to get off work, so he went directly back to the courtyard.
When Gao Zhendong saw Jia Dongxu, he casually asked him how things were going today. Jia Dongxu was very happy: "It went very smoothly, but there were a lot of signatures and seals. I didn't do anything today. "Finish, judging from today's situation, I guess I can get the nickel powder the day after tomorrow."
At this time, Shazhu's dishes were also ready. Half of the chicken was stewed in soup, and half was made into Sichuan-style spicy food. The chicken, Silly Zhu brought the soup basin to the table, but the chicken was missing a leg.
Silly Zhu pointed to the chicken with missing legs: "As you ordered at noon, I sent a leg to the old lady in the backyard."
Gao Zhendong sat down and greeted the two of them: " That’s okay, that’s okay, sit down, let’s do it.”
The three of them were using their chopsticks when a child's cry suddenly came from the door: "Dad, I want to eat chicken."
Gao Zhendong turned around and saw a woman with a stick and a dang, Stand at the door.
Gao Zhendong looked at this woman, then turned to look at Jia Dongxu and Shazhu. For a moment, he really felt the artistic conception of the word "like a world away". For him, this was truly a world away. .
This chapter takes a lot of effort. Arranging hardcore content is difficult, so you have to consider the actual situation.
In fact, the preparation of the electrode has been greatly simplified. First, the author's ability is limited, and second, if this thing is actually written, the content may be too unfriendly for reading.
The vacuum induction furnace was processed according to the plot. In fact, there were small vacuum induction furnaces and even vacuum arc remelting furnaces in China at that time, but there should be no prototype steel rolling mills. In the General Institute of Iron and Steel Research and the Institute of Metal Research, Chinese Academy of Sciences
At this time, there are actually domestic experts who have imitated the K-type, and they have succeeded, but they have not reached the N-type
I will say something similar this time, and I will not repeat it again in similar situations in the future. .
