Bright Sword Military System

Chapter 93 Black Heart Toughening Technology

Zhang Wanhe saw that Wang Xuexin and the old man didn't move for a long time, and thought that he had nothing to do, so he gave Wang Xuexin a step down: "This matter is not urgent, let's use the toughening grenade first, as for the rest... Gradually improve it. Well, there is time!"

The directors of each branch also expressed their approval.

They have been tossed with these difficulties for a long time during this period of time, and they cannot find a solution after repeated discussions. If Xiaodongbei can solve the problem immediately, it is not normal.

Unexpectedly, Xiaodongbei opened his mouth at this time...

"I remember, the little devil seems to have another way, shall we try it?"

Su Xin's eyes widened immediately after hearing this: "You mean, there is another toughening technique?"

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 to the old Chen who was locked up with me, and we talked about it. , I also said at the time why the devil wants to turn into Fa'er tossing this shell..."

"As long as you have an impression!" Zhang Wanhe hurriedly raised his hand to stop others from speaking. He was worried that this question would cause trouble and Xiaodongbei's train of thought would be broken.

He cautiously said to Wang Xuexin: "Let's think about it slowly, it doesn't matter if you try, there is time!"

"It's actually quite simple." Wang Xuexin said, "In addition to burying the shells in the ore and burning them, the devil also seals them in an iron box and burns them!"

"Burning in a sealed iron box?" Zhang Wanhe asked curiously, "Is there such a way of burning?"

"I remember doing this!" Wang Xuexin nodded, then pretended to be reminiscing, and said, "It's true... it needs to be covered with refractory bricks, I don't know the reason, it's just smashing the refractory bricks and laying them on iron. Then put the shells on top of the box, and stuff the shells with refractory bricks. One layer of shells, another layer of bricks, and another layer... After finishing, cover the box, and seal the joint with clay..."

Wang Xuexin won't talk about "black-hearted toughening technology" this time, let alone say that this is a toughening technology from the United States. Anyway, if you know how to do it, you can call it or what country it is. I also doubt: How come you, Xiaodongbei, remember these details clearly?

Su Xin listened to this and said thoughtfully: "Iron box? Still sealed with clay? This is to isolate oxygen!"

Zhang Ruozhong, the director of the second branch, is from a steel factory. He also has some experience in this field in practice. Hearing this, he said strangely: "The white-heart toughening technology we used before is still reasonable. Toughened. But this time... burn without oxygen, will it work?"

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 oxygen is isolated, then the principle is different. Previously, carbon was precipitated by combining oxygen with carbon in iron. This time, oxygen is isolated. Under the condition of maintaining high temperature for a long time, the iron carbide can be decomposed into neutral carbon... This can also achieve the purpose of toughening!"

Wang Xuexin secretly said that he was very powerful, and he was indeed a scholar in Fudan.

The principle is indeed as Su Xin guessed, in the absence of oxygen, the iron carbide is decomposed to precipitate neutral carbon particles, and the iron is transformed into a ductile ferritic iron structure.

"Then..." Zhang Ruozhong asked again: "Why is it better than the white heart toughening technique? If there are still the shortcomings of the white heart toughening, it will make no difference if we fix it!"

Su Xin hesitated, then nodded and said:

"It might be different!"

"We use sand for whitening and toughening, which will inevitably lead to uncertain factors such as uneven oxygen and excessive impurities."

"This results in varying degrees of toughening and even the formation of oxide layers that fall off."

"But if you're using this oxygen-free toughening technology..."

Zhang Wanhe's eyes widened in an instant, and he said, "Oxygen-free toughening, that is to say, there will be no problems with oxide layers and uneven toughening?"

Su Xin nodded heavily: "[-]% of the time, but I'm not sure!"

"This is it!" Zhang Wanhe slapped the table: "Do it right away, if necessary, all other work will be suspended, and you must give me this anaerobic toughening!"

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 is what Xiaodongbei thinks of..."

"I know!" Zhang Wanhe shook his hand towards Su Xin: "You are busy with your work, I am here!"

It makes me happy to say that, this little girl also knows that the fake public welfare is private!

However, this excuse of "fake the public and help the private" makes people have to be convinced.

What Xiao Dongbei said is too simple, just put the things in the iron box and burn them together with refractory bricks!

Which part is missing in this case?
This is a problem related to the upgrade of the entire army's equipment!

If there is no oxide layer peeling off, if it can be uniformly toughened... This is not only a problem of making fragmentation grenades, but also a problem of reducing the scrap rate in series.

Because of these shortcomings, the previous white-heart toughening technology had a scrap rate of up to 50% in cannonball turning.

But even so, the arsenal has to be reorganized, and there is no way, who wants to produce artillery shells?
If anaerobic toughening can be achieved, it will be different, the scrap rate will drop, hehe...

No, we have to keep Xiao Dongbei watching, what if we think of it?
Thinking about it, Zhang Wanhe smiled and said to Wang Xuexin, "I said Xiao Wang, don't you worry about things at the headquarters?"

"Factory manager, I don't know if the head is in a hurry!" Wang Xuexin was a little embarrassed, this was not his decision.

"That's no problem, chief!" Zhang Wanhe waved his hand and said, "I'm going to talk there, you can just say one sentence, will it be bad if you slow down the authentic thing?"

"It's not a bad thing!" Wang Xuexin replied: "It shouldn't be a big problem to slow down for a while. After all, it can't be done in a day or two, or..."

"That's it!" Zhang Wanhe interrupted Wang Xuexin's words: "During this period of time, you should first fix this anaerobic toughening with us, and don't care about the rest, I, Zhang Wanhe, will bear the burden of the big thing. !"

Zhang Wanhe said so, what else could Wang Xuexin say, he could only answer: "Sure, listen to the factory manager!"

Then Zhang Wanhe immediately went to find the chief.

For this matter, Zhang Wanhe is very confident.

This "black heart toughening technology" is no trivial matter... If it can be rectified, then artillery shells, grenades, etc. will be no problem, not only the quality can be improved, but the output is not low.

Isn't it more important than being authentic?
Can his chief not agree?

If the chief does not agree, Zhang Wanhe will fight the factory manager and the logistics chief to quit, and sit at the headquarters to reason with the chief!Talk about him for three days and three nights!
