Zhang Wanhe saw that Wang Xuexin had not made any move for a long time, so he thought that there was nothing he could do, so the conversation changed and he gave Wang Xuexin a step down: "This matter is not urgent, we will use the toughened grenades first, and as for the other... we will improve slowly
Well, we have plenty of time!”
The directors of each branch also expressed their agreement.
They have been struggling with these difficulties for a long time, and they can't find a solution after repeated discussions. It would be unusual for Xiao Dongbei to solve the problem as soon as he comes.
Unexpectedly, Xiao Dongbei would speak out at this moment...
"I remember, the little devil seems to have another trick, why don't we try it?"
Su Xin's eyes widened immediately after hearing this: "You mean, there is another kind of toughening technology?"
Wang Xuexin nodded, but shook his head again, pretending to be unsure: "I'm not sure if it's the toughening technology, I haven't done it. But I did it with Lao Chen, who is close to me, and we talked about it.
, at that time, they also said why the Japanese would turn into Faer and toss the shell shells..."
"As long as it makes an impression!" Zhang Wanhe hurriedly raised his hand to stop others from talking. He was worried that if he asked this question, Xiao Dongbei's train of thought would be interrupted.
He cautiously said to Wang Xuexin: "Let's think about it slowly, it doesn't matter if we try, we have plenty of time!"
"It's actually simple." Wang Xuexin said: "In addition to burying the shells in ore and burning them, the Japanese also sealed them in iron boxes and burned them!"
"Burning in a sealed iron box?" Zhang Wanhe asked curiously: "Is there such a way to burn it?"
"I remember doing it like this!" Wang Xuexin nodded, then pretended to remember, and said: "It means...it has to be laid with refractory bricks. I don't know the principle. It's just to break the refractory bricks and lay the iron.
In the box, then pile the shell casings up, and stuff the shells with broken refractory bricks. One layer of shell casings, one layer of broken bricks, and another layer... After that, cover the box, and seal the joints with clay..."
Wang Xuexin will not talk about "black-hearted toughening technology" this time, let alone that it is a toughening technology from the United States. Anyway, if you know how to do it, you don't care what it is called or what country it is from... I have said too much.
I still wonder: How come you, Xiao Dongbei, remember all these details so clearly?
After hearing this, Su Xin said thoughtfully: "Iron box? And it is sealed with clay? This is to isolate oxygen!"
Zhang Ruozhong, the director of the second branch factory, is from a steel plant. He also has some experience in this field in practice. He said strangely: "Our previous white-core toughening technology still makes sense. Burning it in oxygen oxidizes the carbon in the iron.
It has been toughened. But this time... if it is burned without oxygen, can it be done?"
There was silence in the office, and no one could speak.
Su Xin thought about it for a while and then analyzed: "Maybe it can be done. If the oxygen is isolated, then the principle is different. Previously, the carbon was precipitated by combining oxygen with the carbon in the iron. This time, the oxygen is isolated, which means that the carbon will grow longer."
Let the iron carbide decompose and release neutral carbon while maintaining high temperature for a long time... This can also achieve the purpose of toughening!"
Wang Xuexin secretly said that he is very impressive, and he deserves to be a top student at Fudan University.
The principle is indeed as Su Xin guessed: iron carbide is decomposed under oxygen-free conditions to precipitate neutral carbon particles, and the iron is transformed into a tough ferritic iron structure.
"Then..." Zhang Ruozhong asked again: "Why is it better than Baixin's toughening technology? If there are still shortcomings like Baixin's toughening, there will be no difference if we fix it!"
Su Xin hesitated for a moment, then nodded and said:
"Maybe this is really different!"
"We use sand for white core toughening, which will inevitably lead to uneven oxygen, excessive impurities and other uncertain factors."
"As a result, the degree of toughening varies and even the oxide layer falls off."
"But if this oxygen-free toughening technology is used..."
Zhang Wanhe's eyes widened immediately and he continued: "Anaerobic toughening, which means there will be no oxide layer and uneven toughening problems?"
Su Xin nodded heavily: "That's probably the case, but I'm not sure!"
"It's done!" Zhang Wanhe slapped the table: "Do it now. If necessary, all other work will be suspended. You must get this anaerobic toughening done for me!"
Everyone responded and went out as if putting out a fire.
Su Xin hesitated before going out. She glanced at Wang Xuexin and asked Zhang Wanhe with a complicated expression: "Director, if this reminds Xiao Dongbei of something..."
"I know!" Zhang Wanhe waved his hand towards Su Xin: "You are busy with your business, I am here!"
Just saying this makes me happy in my heart. This little girl knows how to use fake public goods for personal gain!
However, this excuse of “charging public interests for personal gain” is hard to accept.
What Xiao Dongbei said was too simple, just put the things in the iron box and burn them together with the refractory bricks!
What if this link is missed?
This is an issue related to the upgrading of the entire army's equipment!
If there is no shedding of the oxide layer, and if it can be toughened evenly...this is not only a problem of making fragmentation grenades, but also a problem of reducing the scrap rate in a series.
Because of these shortcomings of the previous white heart toughening technology, the scrap rate of shell turning was as high as 50%, which means that at least one of the two shells would be damaged.
But even so, the arsenal has to grit its teeth and have to fix it. There is no other way, who wants to produce artillery shells?
If oxygen-free toughening can be achieved, it will be different. Once the scrap rate is reduced, hehe...
No, we have to keep Xiao Dongbei watching in case he remembers something?
Thinking about it, Zhang Wanhe smiled and said to Wang Xuexin: "Xiao Wang, the matter at the headquarters is not urgent, is it?"
"Director, I don't know if the chief is in a hurry or not!" Wang Xuexin was a little embarrassed. This was not his decision.
"That's no problem, Chief!" Zhang Wanhe waved his hand and said, "I'll tell you there, and you just say a word. Will it be bad if you slow down the matter?"
"It won't be a bad thing!" Wang Xuexin replied: "It shouldn't be a big problem if you take it a little longer. After all, it can't be done in a day or two, or..."
"That's it!" Zhang Wanhe interrupted Wang Xuexin: "In this period of time, you can work with us on the anaerobic toughening first, and don't worry about anything else. I, Zhang Wanhe, will take care of this big thing.
!”
Zhang Wanhe said so. What else could Wang Xuexin say? He could only say: "Okay, listen to the factory director!"
Then Zhang Wanhe immediately went to find the chief.
Zhang Wanhe is very confident about this matter.
This "Black Heart Toughening Technology" is no small matter... If it can really be mastered, then artillery shells, grenades, etc. will be no problem. Not only will the quality be improved, but the output will also be high.
Isn't this more important than being authentic?
Can the leader refuse to agree?
If the chief did not agree, Zhang Wanhe would quit his job as factory director and logistics director, and would sit at the headquarters and reason with the chief! He would talk to him for three days and three nights!
