Chapter 20 It feels like a lifetime ago
"Master Yi, I will ask Engineer Liang to tell you about the working environment, installation conditions, and installation requirements of this device. You and I can discuss the design of the machined parts such as the shell, protective tube, and connectors of this device. The specific production and processing will be left to you. The material to be processed is a high-temperature resistant material with a relatively high hardness, similar to stainless steel or possibly stainless steel. Master Yi, you must consider this first."

Yi Zhonghai nodded confidently. He could say that he had a firm grasp on the processing.

"Chief Wu, I'm sorry to bother you with the temporary borrowing of the factory's equipment, sites, and personnel. Yesterday, General Manager Chen contacted the steel mill, and they agreed to provide us with sufficient nickel powder. Please follow up."

Deputy Section Chief Wu nodded with satisfaction. For a senior middle-level employee like him, dealing with people from other departments in the factory was a piece of cake. Moreover, this matter was both important and hassle-free, which suited his taste very well.

Gao Zhendong continued to make arrangements: "Chief Wu, after you confirm with the steel plant, please invite Master Yi. What is the name of your apprentice?" Gao Zhendong asked even though he knew the answer.

This is probably what Jia Dongxu felt in his heart: "??? Yesterday you were calling me Dongxu Dongxu, but today you turned your face and ignored me?"

Yi Zhonghai was stunned for a moment, then he immediately reacted and smiled widely: "Jia Dongxu!"

"Oh, yes, Jia Dongxu." Gao Zhendong emphasized again, "Master Jia, please cooperate with Section Chief Wu before the processing work begins. Section Chief Wu will be in charge of the relevant matters. As for the specific matters such as running procedures and errands, I will trouble you first, such as the nickel powder for the steel mill I just mentioned."

Gao Zhendong arranged an errand runner for Section Chief Wu, and Section Chief Wu nodded secretly in his heart, thinking that this young man was 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 a timely manner and we will solve them."

Xiao Liu was anxious: "Lao Gao, what about me? What about me?" In state-owned enterprises, younger peers like to imitate older comrades and call each other "Lao X".

"Don't worry, Rongguo. Cooperate with me and let's make electrodes together."

Xiao Liu was dumbfounded: "Doesn't Sister Fang have a Globar stove burning?"

Gao Zhendong smiled: "Sister Fang is testing the material of the protective tube, and we are working on the electrode material here. Except for the nickel powder that has been solved in the steel plant, other materials are mainly solved in the factory. I will give you a list of materials later, and you go to confirm the materials, such as chromium powder, silicon powder, etc. If the factory does not have it, you can come to me again.

"Also, please get the usage time of Corey's small vacuum induction furnace. We will use it next. I will continue to study the material selection and ratio issues. Once you are ready, we will start trial production of electrodes."

Xiao Liu felt more at ease this time: "Okay, leave it to me."

After everything was arranged, everyone took on their tasks and started working separately.

For the biggest problem of electrode preparation, Gao Zhendong plans to use powder metallurgy.

Simply put, it is to mix appropriate amounts of main material powders such as nickel, chromium, silicon, and auxiliary raw materials such as additives, catalysts, trace elements, etc., and after molding, use a vacuum induction furnace to sinter to obtain the finished product.

The advantage of powder metallurgy is that the sintering temperature is much lower than that of the smelting method. Vacuum sintering can bring advantages such as being beneficial to the capacity expansion reaction, less gas participation in the reaction, controllable material flow inside and outside the system, and high-quality products with fewer impurities. The combination of the two can greatly improve the success rate of electrode preparation.

Of course, in practice, it is not as simple as it sounds.

It must be said that a large factory like the Third Rolling Mill is very convenient. Vacuum metallurgical equipment, which was rare in China in the 50s, can be used. Gao Zhendong couldn't help but think of a sentence he often heard in his previous life: "Platform is very important."

As for the problem of research material selection and proportion mentioned by Gao Zhendong, there is actually no such thing. Everything is in his head.

On the contrary, he had to make up some material ratios that were not as good. Otherwise, first, the research was not continuous and it was very suspicious. Second, it was not reliable to say that the best ratio was found without sufficient comparison. R&D continuity is very important. In Gao Zhendong's previous life, his graduation project teacher once said to him that many companies that applied for high-tech enterprises were rejected because of this. Moreover, R&D continuity is difficult to fake. Real experts can see it at a glance, and many of them were even rejected after re-examination.

Everyone was busy, including Gao Zhendong. His "reverse operation" lasted until the afternoon, and people from the team would come to ask him questions from time to time. When he went to the cafeteria to get lunch at noon, Shazhu happened to be at the window, laughing at him for being listless.

After work in the afternoon, Gao Zhendong went back to his room to put down his things, washed his face, and went straight to Sha Zhu's house.

He Yushui saw him at the door and called him sweetly, "Brother Zhendong, you're here? My brother has been talking about you for a while. Do you have any candy? Do you have any candy? Give me two."

He Yushui and Gao Zhendong also became familiar with each other. Gao Zhendong was usually smiling, and when he saw children in the yard, he would always take out some food from his pocket. In addition, Sha Zhu and Gao Zhendong often interacted with each other, so He Yushui was not shy when she saw him and was very friendly.

Nowadays, children are not picky about their food, especially snacks, because they are very lucky to have snacks to eat. If it is candy, it is simply the ultimate enjoyment and can make them happy for several days.

When Gao Zhendong heard what He Yushui said, he took out two crispy candies from his pocket, handed them to her, and walked into the house.

Shazhu worked the night shift the night before and went home after noon. Why do cooks have to work the night shift? Because in such a large factory, there are three shifts, and night shift workers also need to eat.

After returning home to rest, he started to work half an hour before lunchtime until Gao Zhendong came in.

Jia Dongxu was already at Shazhu's house, helping to carry plates and bowls. He took the factory's letter of introduction and related documents to the steel mill to run the nickel powder procedures. When he finished what he could do today, it was almost time to get off work, so he went straight back to the courtyard.

When Gao Zhendong saw Jia Dongxu, he casually asked him how things went today. Jia Dongxu was very happy: "It went quite smoothly, but there were a lot of signatures and stamps to be stamped, so I didn't finish it today. Judging from the situation today, I think I can get the nickel powder the day after tomorrow."

At this time, Sha Zhu's dishes were ready. Half of the chicken was stewed into soup, and the other half was made into Sichuan-style spicy chicken. Sha Zhu brought the soup bowl to the table. The chicken was missing a leg.

Sha Zhu pointed at the chicken with a missing leg and said, "According to your instructions at noon, I sent a leg to the old lady in the backyard."

Gao Zhendong sat down and called to the two of them: "That's fine, that's fine, sit down, sit down, let's get started."

The three were just starting to eat when a child suddenly called out from the door: "Dad, I want to eat chicken."

Gao Zhendong turned around and saw a woman with Banggeng and Xiaodang standing at the door.

Gao Zhendong looked at the woman, then turned to look at Jia Dongxu and Sha Zhu. For a moment, he really felt the artistic conception of the words "as if in a different world". To him, this really was a different world.

　This chapter took a lot of effort. It was difficult to arrange the hardcore content, and I had to consider the actual situation.

　　In fact, the preparation of electrodes has been greatly simplified. Firstly, my ability is limited, and secondly, if this thing is really written down, I am afraid the content will be too unfriendly to read.

　　The vacuum induction furnace was designed to suit the plot. In fact, at that time, there were small vacuum induction furnaces and even vacuum arc remelting furnaces in China, but there should not have been a prototype of a steel rolling mill.
　　During this period, there were actually some experts who copied the K-type in China, and they succeeded, but they didn't make the N-type.

　　I will only say similar things once, and I will not repeat them in similar situations in the future.
