Chapter 83 Young man, who are you scolding
Gao Zhendong smiled: "Hey, it's all a habit in the army."
Staff Lin was stunned: "Have you ever been a soldier?"
Gao Zhendong nodded: "I withdrew from the battlefield in 1953 and changed careers in 1955."
Old Chen praised him: "He received first-class merit twice on the battlefield. , three times second-class meritorious service, a combat hero, and now he is still the deputy captain of the main militia team in the factory.”
Staff Lin and the others who accompanied him were in awe, and together they solemnly saluted Gao Zhendong.
The comrades at the Prairie Tractor Factory are also full of admiration. To be honest, before I met him, I never thought that this comrade was so young. Combined with this experience, Xiao Xiao is considered a legend. .
Gao Zhendong was blinded now, and he couldn't return the military salute. Then he thought, I'm not the deputy captain of the militia, so that's okay, so he solemnly returned the military salute.
Although strictly speaking it is inappropriate, in this case, it will only be spread as a good talk, and no one will be too full to find fault.
Everyone sat down and Mr. Guan told Gao Zhendong the whole story of why he came to see him this time. He was still very embarrassed: "That's probably what happened. I'm sorry to say it. Gao Gong, you I have taken leave to rest, and I am here to trouble you.”
Gao Zhendong didn't care. He was mainly resting and resting his brain. He didn't have anything to do. Besides, it was just for communication, so it had no impact at all.
Ever since he learned that Mr. Guan was from the Prairie Tractor Factory, Gao Zhendong probably knew their purpose. If he remembered correctly, the domestic nickel supply was almost gone.
The nickel-free 601 cast armor steel was developed by the group of people in front of me around April 1960, and at this time, it should still be under research.
The 3Z-T1 and 3Z-T2 that Gao Zhendong took out are actually the future 616 welded armor steel and 623 cast armor steel.
The former replaces 603 steel, and the latter replaces 601 steel, but neither of them has been researched yet.
However, 601 steel has one advantage over the 623 steel produced by Gao Zhendong, that is, it does not require any nickel. However, defects also exist. At this stage, the two can be adjusted and replaced according to the material supply.
He shook his head: "Mr. Guan, you are so polite. It doesn't matter to me. If you have anything to ask, please tell me."
Mr. Guan is not polite either. It's all for construction. , Gao Zhendong said it didn't matter, so naturally he wouldn't be coy.
"I asked one by one, mainly because there were too many surprises for me and I had a lot of questions, haha." Mr. Guan made a joke and continued to ask.
“Are 3Z-T1 and 3Z-T2 qualified for mass production?”
Gao Zhendong nodded: "No problem, as long as the materials and equipment are ready, mass production is not a problem."
"Does your factory have the production conditions?"
Director Yang answered this question Past: "To be honest, we are a steel rolling mill. Judging from the situation of our factory, we may not have the conditions for large-scale production in a short time and lack of equipment."
This made Mr. Guan a little confused: "Hey, this ."
However, Director Yang really wanted to let it go, because the third rolling mill cannot have this capability in a short time. Depending on the situation, it is obviously impossible to wait for this matter, so just let the matter go: "This You can apply to our department to transfer production technology.”
In this day and age, this kind of thing happens all the time. In a game of chess across the country, the ownership of technology is not so clear.
Mr. Guan was a little moved: "Zhendong, what do you think about it?"
This is because he is afraid that the third rolling mill and Gao Zhendong think they are here to pick fruits, so not only the director of the third rolling mill You should listen to what he says, and Gao Zhendong, as the only researcher, should also respect his opinions. Gao Zhendong nodded: "This is a way. Our factory will not have this capability in a short time. We have no steelmaking plants and equipment for mass production, and transportation is also a problem."
< br>Anyway, for him, the name of the inventor cannot escape, the name is there.
In his situation, combined with the social environment, economic interests are not important.
Since Director Yang is willing to let the matter out, it will be the same no matter where it is produced.
Mr. Guan and Staff Officer Lin were greatly moved by the selflessness of the Third Rolling Plant and Gao Zhendong, and they thanked them deeply.
Mr. Guan collected himself and continued to ask questions he cared about.
“How much nickel, molybdenum and rhenium are contained in 3Z-T2 cast steel?”
"They are 0.8%~1.3%, 0.25%~0.45%, and 0.02%~0.12% respectively."
Mr. Guan was very happy when he heard this ratio. The weight of nickel in the steel they use now is It’s about 3.8%. With the body and turret, a tank uses more than 700 kilograms of nickel.
The combination of Gao Zhendong’s 3Z-T1 and 3Z-T2 can directly reduce the amount of nickel to about 100kg.
“Have you considered further reducing the amount of nickel used in 3Z-T2?”
“You have considered it, but further reducing the amount of nickel will cause two problems: First, hardenability The shortcomings are that the low-temperature performance is poor. I was not good at it and couldn’t do it anymore. When I was doing this, it was for thermocouples. I happened to trial-produce other better materials, so I didn’t continue to work on it.”
One of these two problems affects the performance and quality of the finished product, and the other affects the environmental adaptability of the finished product.
In fact, these two issues mentioned by Gao Zhendong are the main reasons for future research on 623 steel to replace 601 steel. In terms of hardness alone, 623 and 601 are basically on the same level.
There is another problem that Gao Zhendong did not mention and cannot say now, that is, the source of raw materials for 601 steel is also difficult. Although nickel is no longer used, the consumption of some other scarce elements has increased.
But at this time, the nickel problem is the most prominent. 601 steel has solved the nickel problem, which is very successful.
Because 601 steel has not been developed yet, there is naturally no way to discuss this issue.
Listening to Gao Zhendong say that his own skills are poor, Mr. Guan and the comrades of the Grassland Tractor Factory have mixed feelings. Young man, who are you scolding?
In fact, they will never know that Gao Zhendong's level in metallurgy is really much worse than them, he just copied the answers well.
Mr. Guan himself is an expert in making armor steel. He thought for a while and nodded: "It makes sense. This problem may indeed arise. Comrade Zhendong has done too solid a job in practice."
Gao Zhendong thought for a while and asked: "Are you worried about the amount of nickel used?"
Mr. Guan nodded: "Yes, the less the better now. But in this situation, It has exceeded our expectations. We have solved more than half of the problem. It can even be said that we have basically been able to meet the production requirements from being unable to do anything at all. Zhendong, you deserve the most credit.”
Gao Zhendong has great admiration for the group of people in front of him who have truly created the first generation of domestic nickel-free armor steel from scratch. To use the metaphor of writing online articles, he is just a fan writer, and they are It's something original.
