"That's what he said, ready to build guns and cannons?"

Just when Bai Yi and others were busy around the precision forging machine, in the newly built Soviet expert club of Baiyun Factory, the soothing Swan Lake dance music was melodiously resounding through the hall, but Kempf, who was in it, seemed to be deaf to the beautiful melody, but stared at Repin next to him in surprise: "You can't hear it wrong, with Bai Yi's stubborn character of not giving up until he reaches his goal, he will actually compromise?" ”

"Even if I have a problem with my ears, my eyes shouldn't be wrong!"

Repin, who was shaking the wine glass in his hand and squinting to enjoy the beautiful music, did not care about Kempf's surprise, opened his eyes and pointed, and said with a smile: "During your time in Moscow, I supervised their situation almost every day, Bai Yi and they were using the precision forging machine in full accordance with the agreement, if I hadn't seen it with my own eyes, I wouldn't have believed it, but it is true, no matter how strong the Chinese's self-esteem is, they have to bow their heads in the face of existence stronger than him, this is the truth!" ”

Kempf nodded when he heard this, immediately took a sip of the red wine in the glass, and said with some unease: "I'm afraid that they are making a trick, you must know that those Chinese are very cunning." ”

"Tricks? Haha~~~"

Hearing this, Repin couldn't help laughing, and after a while he calmed down and continued: "If I can use a trick on a scrapped machine, then I can swallow the entire precision forging machine, and with their technical level, I can't make it for them in half a century!" ”

"Scrap machines?"

Kempf accurately captured the key point in Repin's words, and hurriedly straightened up from his seat: "The precision forging machine that just arrived was scrapped?" ”

"You haven't been in Moscow lately, you don't know that the precision forging machine has been here for less than a week, and it was scrapped by those stupid guys......"

Saying that, a trace of sarcasm flashed on Repin's face, and then he slowly said the ins and outs, it turned out that after the installation of the precision forging machine, Bai Yi and others were indeed using it according to the agreement, but the problem was that their operation of the machine was too barbaric, so that there were several failures in a few days.

At first, Bai Yi and others were able to repair it, but later, with more and more failures, the difficulty of maintenance became more and more great, and in the end they had to dismantle the entire precision forging machine.

I had no choice but to call Soviet experts over, but I didn't expect that many parts were inexplicably lost when they disassembled, and even if Da Luo Immortal came, it would be useless.

"With this inferior quality and rough management, you still want to make a fuss about the precision forging machine? If we had known that this was the result, we wouldn't have had to think so much about it, they would have been able to play themselves to death! ”

After Repin finished speaking, Kempf took a long breath, thinking that Bai Yi was going to make some kind of moth, but he didn't think about it, but he lifted a stone to hit his own feet, and then Kempf finally put his mind at ease, and finally showed a smile, and raised his glass at Repin: "Next, let's see how our little comrade Bai Yi is anxious." ”

"I believe it must be more attractive than Swan Lake!"

Repin held out his glass and touched Kempf, and then unbridled laughter resounded through the hall with gorgeous notes......

Bai Yi was not anxious, but he did have a headache.

The reason is that the latest precision forging machine has not yet met his ideal requirements, because in his planning, in the general machine gun project that is being promoted, the most critical barrel can only rely on the precision forging machine to achieve the theoretical design value.

After all, China is still very backward in terms of basic materials, and high-value alloy steel for firearms cannot be produced at all, so it can only rely on nickel-containing alloy steel imported from the Soviet Union.

Coupled with the fact that the Soviet Union has always discounted export products, the mechanical properties of imported nickel-containing alloy steel can only barely meet the requirements for weapons production.

It was impossible to achieve the durability of German firearms in the early days of World War II.

In this regard, Bai Yi has long organized people to conduct experiments, and according to the existing process, the barrel of a machine gun made of nickel-containing alloy steel imported from the Soviet Union has a service life of no more than 5,000 rounds, and less than 3,000 rounds.

On average, the service life of only 4,200 rounds is a lot, but on the real battlefield, these more than 4,000 rounds of ammunition are only a few bases, and it is not enough to fight an ordinary positional defensive war.

What's more, the battlefield environment is changing rapidly, it is difficult to estimate what situation will be encountered, and the life of the barrel is sharply reduced, because of this, the service life of the general machine gun must reach more than 10,000 rounds, only in this way can the minimum continuous combat requirements of the troops in a high-intensity war environment be guaranteed.

However, now, with the technology currently mastered by Baiyun Factory, there is no way to make the barrel reach this value, so it is necessary to find a way to improve the quality of the barrel when the material cannot be broken through.

As for how to mention it, of course, it is to seek a breakthrough in processing technology.

The solution proposed by Bai Yi is the cold forging process commonly used in his previous life for body barrel weapons, which can not only minimize the loss of materials, but also enhance the mechanical properties of materials, so that the processed barrels and barrels have stability and service life far beyond similar equipment.

Because of this, after the Austrians successfully applied the cold forging process to the barrel of the gun from the 60s, this magic process that is like adding a buff to a firearm was quickly popularized in the West, and China introduced this process to China in the 80s, and it was also quickly rolled out, so as to surpass the Soviet Union in the manufacture of its own body weapons in one fell swoop.

Bai Yi still remembers the shocked look on the face of his Russian counterpart when he went to Russia for academic exchanges, when the 12.7mm heavy machine gun made by the cold forging process fired 20,000 rounds of high-power ammunition continuously and the barrel was not abnormal.

Because since the collapse of the Soviet Union, Russia, which has a sluggish economy, has not fully mastered the manufacturing technology of cold forging process until the 10s of the 21st century, of course, only shock and envy.

However, the cold forging process is simple to say, but it is not easy to really do, the most important thing is the equipment, Bai Yi's previous life is good, the cold forging equipment can be produced in China, and it can be bought at any time.

But now Bai Yi is in the early fifties of the twentieth century, and the cold forging process is only a new topic discussed in the papers of university professors, far from meeting the practical requirements, and it is not easy to turn ideas into reality.
