Chapter 102 ESR's Foot (3k)

There is nothing much to say about the subsequent research and development work of ESR. Gao Zhendong was just loaned to the computing institute for a period of time, and it is not a life-and-death separation. He should be arranged to work normally, and be told the precautions and key points.

After he arranged the matters during this time, the other staff left the ESR test workshop, and the ones left were from the continuous sliding crystallizer experimental group.

With everything ready, Gao Zhendong gave the order to start the experiment.

The slide crystallizer can be imagined as a bucket without a bottom that rises upward.

Its bottom plate was originally a bottom water tank. As the metal ingot solidified after remelting, its bottom plate became the top of the ingot. As the solidification height of the ingot increased, the sliding crystallizer would automatically rise to ensure that the molten pool and electroslag were always in the barrel.

The advantage of doing this is that continuous casting can be carried out to produce metal ingots whose height far exceeds the depth of the crystallizer.

Of course, this is not considered continuous casting. Real continuous casting can change the shapes of different cross-sections, but that is a matter for the future.

Back to the sliding mold control system test, this needs to be tested in conjunction with the successful consumable electrode control system.

When the test started, the scene was no different from the consumable electrode control system joint debugging test, with flashing electric lights and a low buzzing sound.

As the ingot at the bottom of the mold solidifies and the temperature reaches the action point, the sliding mold begins to rise according to the preset action.

As the sliding crystallizer is lifted, the state of the molten pool and electroslag is changed, and the consumable electrode control system also begins to actively adjust to maintain the stability of the remelting current.

The control of these actions is not performed by digital circuits. Not to mention single-chip microcomputers, even the logic gate integrated circuits are not known yet. They mainly rely on analog control circuits to work.

As time passed, a metal ingot grew higher and higher under the sliding crystallizer. The top of the ingot, near the bottom of the sliding crystallizer, was slightly reddish, which was the color of the metal ingot after solidification but not yet completely cooled.

Finally, the sliding crystallizer reached the predetermined highest point, and a metal ingot with a large aspect ratio appeared in front of people.

Gao Zhendong issued an order to stop the test, and people were familiar with the procedure and carried out the stopping procedure in an orderly manner.

After everything was completed, Sister Fang began to summarize the monitoring records of each testing instrument and do preliminary processing with the data analysts.

Finally, Gao Zhendong took over the preliminary processed test records from Sister Fang.

The sliding speed, height and position deviation are all within the ideal range. At the same time, the records of the consumable electrode control system also show that the remelting current is well controlled during the sliding process and is within the expected range.

As for the comparative inspection and testing of metallographic, mechanical and material properties, that will be a matter for the future. It cannot be done now as the ingot is still hot.

After Gao Zhendong finished reading all of them, he picked up the record and waved it in the air amid everyone's anticipation: "Comrades, our ESR sliding crystallization experiment has achieved initial success!"

There was applause all around, but the noise was no longer as loud as when the consumable electrode control system joint debugging test was successful. As the entire project development was basically going smoothly, everyone's emotional threshold was raised.

Following Gao Zhendong, the team members who have experienced various successes and setbacks have become accustomed to the success of this kind of phased experiment. Even if there is a failure, the worst that can happen is to analyze the cause, adjust the plan, optimize the equipment, and try again.

If there is a problem, try your best to solve it. If you can't solve it yourself, ask chief designer Gao Zhendong, deputy project commander, and commanders to solve it.

Not being arrogant in victory and not being discouraged in defeat, this is the temperament that a mature scientific research team should have.

However, the experiment was successful, so cool!!!
After everyone was happy, Gao Zhendong continued to arrange the follow-up work: "Now the ingot temperature is still high, the metallographic and mechanical properties, material characteristics, and fixed mold and sliding crystallization product comparison tests are left to you."

The team members on the scene gave a chorus of assurances.

Gao Zhendong continued, "I can feel everyone's determination and confidence. If there are any problems, don't worry, we will study, adjust and optimize. Up to now, it can be said that the ESR process research and improvement has already stepped half a foot into the door of success. During the time I am away from the factory, you can come to me at any time if you have any questions, and the computing institute will fully cooperate and try to facilitate everyone."

There was a burst of voices from below saying, “Don’t worry, Director Gao.”

Liang Faming pushed his glasses on the bridge of his nose and assured Gao Zhendong: "Director Gao, don't worry, with such a good foundation laid by you, the project will not have any problems. Besides, you will still be there in the end, haha."

After thinking it over carefully and arranging everything, Gao Zhendong said hello to everyone and left the ESR test workshop.

Before rushing to the Institute of Computing to support the work on the transistor computer system, he still had some chores to take care of, and the remaining half day was just right for doing these things.

After working until the afternoon, Gao Zhendong walked out of the technical department office building. Next to the office building, Gao Zhendong unexpectedly met Wang Dezhui.

Gao Zhendong was very surprised. Even if there was a joint construction between the police and the public, he usually didn't have time to come, and it was difficult to meet him in the factory.

Rushing forward and punching him first, Gao Zhendong asked cheerfully, "Big Boss Wang, how come you have time to come here today?"

Wang Dezhu also looked happy: "Your factory said that it would adjust the location of the co-built duty room, make a bigger and more convenient duty room for us, and improve the working conditions of the liaison officers stationed in the institute. I came to take a look."

After saying that, he pointed and said, "Look, it's right there."

Following his hand, I saw that the new duty room was located on the first floor of the technical department office building, right on the road leading to the offices of the first research laboratory of the technical department. Wow, the factory is taking advantage of the police station, these old foxes.

Gao Zhendong was very happy: "This place is great, it's a pity you don't come here often, otherwise you can come and sit with me anytime. Come on, come and sit in my own office."

Gao Zhendong now has an independent office. In addition to the importance of his work involving a lot of secrets, the topics he talks about with visiting guests often also involve these.

So when the factory set up the first research laboratory, they simply arranged an independent office for him and equipped it with a safe. However, Gao Zhendong rarely used this thing. How could he have his own storage and safety?
Wang Dezhu had already finished his work. Hearing what he said, he walked with him to the office and joked, "Old platoon leader, you are so fast. You already have your own office."

Gao Zhendong patted his chest and said, "That's right, haha, double deputy section chief, deputy section chief of the training section of the security department, and director of the first research room of the technical department, hehe."

There is nothing for both of them to hide in front of each other, so just show your most relaxed side.

Wang Dezhu didn't want to talk to him and threw a "6" at him.

After entering the office, Wang Dezhu looked around and said, "Old platoon leader, your place is great. I want to come here often, haha."

Gao Zhendong agreed while making tea: "I was just worried that you wouldn't come."

Putting the water in front of Wang Dezhuo, Gao Zhendong sat down and the two chatted about recent events.

Seeing that it was almost time for dinner, Wang Dezhu slapped his thigh and said, "Let's go to my house for dinner."

Gao Zhendong picked up his bag and said, "Let's go!"

I haven't played with Xiaomei for a while, and I miss her a lot.

As soon as she entered Wang Dezhu's house, Xiaomei rushed over with a long childish voice: "Uncle Gao~~Uncle~~~"

Gao Zhendong picked her up and laughed loudly, which made Wang Dezhu's eyes twitch and he kept muttering, "My daughter is gone, my daughter is gone."

After holding Xiaomei and playing with her for a while, Gao Zhendong put her down and handed her a handful of chocolate.

Wang Dezhu recognized this thing and knew it was very valuable, but he did not stop it.

Gao Zhendong said, "Xiao'e got it for me. Her family can get it. As long as Xiaomei likes it, that's good."

Xiaomei's lips were all black from eating so much, and she was very happy.

Wan Yueqin was already very ill, so Gao Zhendong and Wang Dezhu simply cooked for themselves. It didn’t matter if their cooking skills were just average, but it was not inedible.

As they worked, Wang Dezhu listened to Xiaomei's laughter. The scene brought back some memories for him, and he suddenly said, "It would be great if my old comrades could see this world."

Gao Zhendong stopped what he was doing and waited for a while before speaking: "You are from the public security department. Do you know the situation of the comrades who are still alive?"

This is very difficult. In this era, transportation and communication are too backward. Ordinary people can only communicate through letters, and it is easy to lose contact.

An ancient poem says, "The war has been going on for three months, and a letter from home is worth ten thousand pieces of gold." In fact, it was still basically the same at that time, except that there was no war.

Wang Dezhu thought for a moment and said, "I know a little bit and I'm writing to him, but it's hard to meet him in person."

"Is everything okay?"

"They were all transferred and resettled according to regulations, but some had difficulties because of the large number of family members and heavy burdens."

Hearing this, Gao Zhendong suddenly had an idea and remembered something, and became thoughtful.
-
The next morning, Gao Zhendong rode his bike to the computing office at the agreed working time.

Director Li and Chief Engineer Chi had already been waiting at the gate of the Institute of Operations with a group of people, and expressed their warm welcome to Gao Zhendong.

After a round of greetings, Gao Zhendong and they came to the training ground for transistor computers. Gao Zhendong took out a stack of papers and discussed with Director Li.

"Director Li, Chief Engineer Chi, this is the support work arrangement I drafted. Please take a look and see if it is suitable. If it is, we will follow this plan."

Director Li and Chief Engineer Chi took the plan and read it carefully.

Chief Engineer Chi looked at it and asked, "Comrade Zhendong, please also check whether our preparations are sufficient and whether there is anything that needs to be added."

Gao Zhendong looked at the equipment list on site, checked it carefully, and then made a request: "Chief Engineer Chi, if you have extra magnetic core memory, please provide it. The larger the capacity of a single unit, the better."
