Chapter 102 A Foot of ESR (3k)
There is not much to say about ESR’s follow-up research and development work. Gao Zhendong was only borrowed to the computing center for a period of time, and it was not a separation between life and death. He arranged his work normally and made it clear and careful. Matters, just focus on the difficult ones.
After he made arrangements for borrowing this time, the other personnel left the ESR test workshop. The remaining ones were the people from the continuous sliding crystallizer experimental group.
With everything ready, Gao Zhendong gave the order to start the test.
The sliding crystallizer can be imagined as a barrel without a bottom that lifts upward.
Its bottom plate is initially a bottom water tank. As the solidified metal ingot is generated after remelting, its bottom plate is the top of the metal ingot. The sliding crystallizer will automatically lift upward as the solidification height of the metal ingot increases to ensure melting. The pool and electroslag are always in this bucket.
The advantage of this is that it can continuously cast ingots and cast metal ingots with a height that far exceeds the depth of the crystallizer.
Of course, this is not considered continuous casting. Real continuous casting can change different cross-sectional shapes. That will happen in the future.
Back to the sliding crystallizer control system test, this is a joint debugging test with the already successful consumable electrode control system.
At the beginning of the test, the scene was no different from the joint debugging test of the consumable electrode control system, with flashing electric light and a low hum.
As the ingot at the bottom of the crystallizer solidifies, the temperature reaches the action point, and the sliding crystallizer begins to lift according to the preset action.
While the sliding crystallizer is being raised, the conditions of the molten pool and electroslag are 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 carried out by digital circuits. Let alone microcontrollers. Even the logic gate integrated circuits are not known where they are now. They mainly rely on analog control circuits to work.
As time passed, under the sliding crystallizer, a metal ingot became higher and higher. The top of the metal ingot, close to the bottom of the sliding crystallizer, was slightly red. That was because the metal ingot had not completely solidified. Cool color.
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 the order to stop the test, and everyone was familiar with the road and carried out the stop procedures in an orderly manner.
After everything was completed, Sister Fang began to summarize the monitoring records of each testing instrument and did 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 during the sliding process, the remelting current is well controlled and within the expected range.
As for the comparative inspection and testing of metallographic and mechanical properties and material properties, that is a matter for later. It cannot be done now, as the ingot is still hot.
After Gao Zhendong read it all, with everyone's expectations, he picked up the record and waved it in the air: "Comrades, our ESR sliding crystallization test was initially successful!"
There was a round of applause from all around, However, the movement is no longer as big as the successful joint debugging test of the consumable electrode control system. As the research and development of the entire project proceeds smoothly, everyone's emotional threshold has increased.
Following Gao Zhendong, the team members who have experienced many successes and setbacks have become accustomed to the success of this kind of phased experiment. Even if it fails, the big deal is to analyze the reasons, adjust the plan, and optimize Equipment, once again is.
If you have a problem, work hard to solve it. If you can't solve it yourself, go to the chief designer Gao Zhendong, deputy project commander, and general commanders to solve it.
Don’t be arrogant in victory and don’t be discouraged by 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: "The ingot temperature is still high now, and the tests on metallographic and mechanical properties, material properties, and comparison of fixed casting molds and sliding crystallization products will be left to everyone. ”
The team members on the scene sounded reassurances.
Gao Zhendong continued: "I feel everyone's determination and confidence. If there are problems, don't be afraid, we will study, adjust and optimize. At this level, it can be said that ESR process research and improvement , most of them have already stepped into the door of success. During this time when I am not in the factory, you can come to me at any time if you have any questions, and the computing center will fully cooperate and try to make it as convenient as possible for everyone.”
There was a sound of "Don't worry, Director Gao" below.
Liang Fafa pushed up the glasses on the bridge of his nose and assured Gao Zhendong: "Director Gao, don't worry, with you laying such a good foundation, there will be no problems with the project. Besides, you will still be here in the end, haha."
After thinking carefully, everything was arranged. Gao Zhendong said hello to everyone and left the ESR test workshop.
Before rushing to work on the transistor computer system supported by the computing center, he still had some chores to deal with, and the remaining half day was perfect for doing these things.
Working until the afternoon, Gao Zhendong walked out of the office building of the Technology Department. Next to the office building, Gao Zhendong unexpectedly ran into Wang Dezhu.
Gao Zhendong was very surprised. Even if the police and citizens were involved in joint construction, he usually would not have time to come over. It was difficult to meet him in the factory.
Rushing up and punching him first, Gao Zhendong asked cheerfully: "Big Lao Wang, why are you free today?"
Wang Dezhu also looked happy: "Your factory said that it would adjust the jointly built duty room. Give us a larger and more convenient duty room, and improve the working conditions of the liaison officers stationed in the station. I'll come over and take a look."
After saying that, he pointed: "Here. It’s right there.”
Looking along his hand, the new duty room is located on the first floor of the Technical Department Office Building, right at the entrance to the offices of the Technical Department’s First Research Office. On the way. Oh, the factory is just taking advantage of the police station, these old foxes.
Gao Zhendong was very happy: "This place is good. It's a pity that you don't come here often. Otherwise, you can come to my place anytime, walk around, and go to my office."
Gao Zhendong is now He has an independent office. In addition to his important work, which involves a lot of secrets, his conversations with visiting guests often involve them.
So when the factory established the first research office, they simply arranged a separate office for him and equipped it with a safe. However, Gao Zhendong didn’t use this thing very much. He could have his own storage safe. ?
Wang Dezhu had finished his work. After hearing what he said, he walked with him to the office and joked: "Old platoon leader, you can do it at this speed. You already have your own office."
Gao Zhendong patted his chest: "That's, haha, double deputy section, deputy section chief of the training section of the security department, director of the first research office of the technical section, hehe."
Both of them have nothing to hide in front of each other, just show their 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 nice, I want to come and sit here often, haha."
Gao Zhendong was making tea while Agree: "I'm afraid you won't come."
Putting the water in front of Wang Dezhu, Gao Zhendong sat down, and the two chatted about recent events.
Seeing that it was almost time for dinner, Wang Dezhu slapped his thigh: "It's better to catch the sun than to catch it. Let's go to my house for dinner."
Gao Zhendong lifted his bag: "Let's go!"
It's been a while since I've teased Xiaomei, which is weird.
As soon as she entered Wang Dezhu's house, Xiaomei's childlike voice came over to her with a long voice: "Uncle Gao~~~Uncle~~~"
Gao Zhendong picked her up and laughed loudly. Laughing, Wang Dezhu's eyes twitched and he muttered, "My daughter is gone, my daughter is gone."
After holding Xiaomei in his arms for a while, Gao Zhendong put her down, touched a handful of chocolates and handed them to her.
Wang Dezhu knew this thing and knew that Jin Gui was there, but he did not stop it.
Gao Zhendong said: "Xiao'e got it for me. If her family can get it, it's fine if Xiaomei likes it."
Xiaomei's mouth turned black, she was so happy Very.
Wan Yueqin was already very heavy, so Gao Zhendong and Wang Dezhu simply cooked by themselves. Their cooking skills were average, but it wasn't like they couldn't eat.
While the two were busy, they listened to Xiaomei's laughter. Wang Dezhu was a little moved by the scene, and suddenly said: "It would be great if all the old comrades in arms could see this world."
Gao Zhendong stopped. He stayed for a while before speaking: "You are from the police station. Do you know the situation of your comrades who are still alive?"
This is difficult. In this era, transportation and communications are too backward. , ordinary people can only communicate by letters, and it is easy to lose contact.
The feeling of an ancient poem saying, "The flames of war last for three months, and a letter from home is worth ten thousand gold." In fact, this is basically still the case at this time, but there is no flames of war.
Wang Dezhu thought for a while: "I know a little bit and am writing letters, but it is difficult to meet in person."
"Is everything okay?"
"They are all relocated according to regulations, but some have some difficulties because of the large family size and heavy burden."
Hearing this, Gao Zhendong had a bright idea in his head. For a flash, I remembered something, thoughtfully.
——
Early the next morning, Gao Zhendong rode to the computing office according to the agreed work time.
Director Li and Chief Engineer Chi had already led a group of people to wait at the gate of the computing center and expressed a warm welcome to Gao Zhendong's arrival.
After a while of greetings, Gao Zhendong and them came to the training venue of transistor computers. Gao Zhendong took out a stack of paper and discussed with Director Li.
"Director Li, Chief Engineer Chi, this is a support work arrangement that I drafted first. You can see if it fits. If so, we will follow this plan."
Director Li and Chief Engineer Chi took over the plan and read it carefully.
While looking at it, Chief Engineer Chi asked: "Comrade Zhendong, please also see if our preparations are sufficient and if there is anything that needs to be added."
Gao Zhendong looked at the equipment list on site, checked it carefully, and made a request: "Chief Engineer Chi, if you have extra magnetic core memory, can you provide it? The larger the capacity of a single unit, the better."
