Of course Qin Zhenhua knew what the other party was saying. Since Qin Zhenhua entered the first machine factory, he made a big splash. As an apprentice, he relied on his own strength to increase the power of the armor-piercing bomb a lot, making the whole body
The army was moved by it, and relying on this achievement to correct its father's reputation, and then sang all the way.
Qin Zhenhua's experience is incomparable. In a few years, he has risen to the real-power leadership in the factory. Moreover, his subordinates have led to the development of projects one after another, which is jaw-dropping and envious.
Even because of Qin Zhenhua, the superiors made a more important decision, called young people being the head! All factories should vigorously promote young people because young people are energetic, young people are thoughtful and enterprising, while the elderly are
Most of them are self-consistent and conservative.
Qin Zhenhua completely set off a wave. At the Second Machine Factory, this young man named Rong Qiang entered the factory last year, but after entering, he kept showing his own
Straight.
After a year, I have mastered the most sophisticated technology of the Second Machine Factory: the opening of the barrel bore.
The second machine factory is a cannon. There are many steps to build cannons. First, it is the smelting of cannon steel. This special alloy is obtained by secondary smelting in the second machine factory. Then, on the blank, it is first opened.
A hole, then expand the hole, and it becomes a gun barrel, and then the body tube is tightened. If it is a rifled gun, there must be a rifling step, and other processes such as chrome plating inside the gun barrel.
In short, these processes are quite complex, but the most important one is opening.
The length of the barrel is often several meters, and a small hole is first made on it. The accuracy of this hole directly determines the accuracy of this gun. Even in the second machine factory, the skilled master will not exceed twenty.
Yes, Rong Qiang is simply a genius, and he quickly mastered this craft.
Moreover, after discovering that the process of the thermal sheath of the gun barrel was not yet perfected, he thought about it alone after getting off work and wasted a few sets of aluminum, and he actually made it happen!
This made the factory very excited. At the end of the year, the factory also gave Rong Qiang an additional year-end reward.
When Qin Zhenhua heard about the young man's deeds, he immediately became interested: "It's great. When you have time, let me meet this young man."
Hearing Qin Zhenhua's words, Xie Huimin suddenly became alert: "This, you have to say in advance that Rong Qiang is from our Second Machinery Factory, so don't make any tricks."
Obviously, the incident during the Chinese New Year had spread. A group of workers in the Hongxing Machinery and Electrical Factory ran to the Machinery Factory to cause trouble. As a result, Qin Zhenhua only used one meal, a meal full of meat.
These workers were bribed, and a large number of workers joined the first machine factory. Even if they were temporary workers, they were willing to live a life of eating meat every day in the first machine factory.
It is said that the director of Hongxing Electrical Factory went to the capital to make a big fuss. I don’t know what the result was. Judging from this, there should be no result in the end.
After such a big loss, Hongxing Electrical Factory almost suffered a disability, and its future fate can be imagined. Now, Xie Huimin almost regrets telling Qin Zhenhua about these things. If Qin Zhenhua falls in love, he will dig up this person.
What should I do if I go to their first machine factory?
At that time, Rong Qiang said he was leaving, and everyone couldn't stop him.
Qin Zhenhua smiled and said, "Old Xie, what you said seems to me just like poaching others' corners. It's so boring. As long as this young man can build cannons for us and advanced cannons, isn't he still helping us with a factory?
”
Xie Huimin then relaxed. This is true. Second Machine Factory and First Machine Factory are brothers. Second Machine Factory builds guns, First Machine Factory builds complete vehicles. Second Machine Factory provides parts to First Machine Factory.
It would be too unreasonable for them to poach people from themselves.
The moment the two of them were talking, the guests from Lao Ba there had been watching around the fort for a long time.
This is just a test gun, not an automatic loader, so there is still a manual loading mechanism inside. Parker stood there and said, "Can we see the power of this gun?"
"Of course," said Xie Huimin: "Our gun is currently undergoing preliminary testing. The previous guns have tested the chamber pressure. The tank gun has the current measurement results that it can withstand the chamber pressure stably
, about 470 MPa.”
The test was carried out bit by bit, just like the 120mm tank gun on our own. After repeated tests, the chamber pressure has stabilized to about 560 megapas, while the 125mm tank gun on our own, in the initial test,
It increased little by little, but it only reached about 470 megapas.
Even so, it is already very good, because the 2A46 tank gun exported by the Soviets had a chamber pressure of only about 450 megapas. The chamber pressure tested has exceeded that of the Soviet tank gun!
"This data is very good, it has surpassed T-72." Parker said.
They are comparing everything to the T-72, as long as they are higher than the T-72.
Then, under their gaze, the shells were moved out from the ammunition box beside them. When they saw the shells, the people from Lao Ba's inspection team immediately opened their eyes: "This, this shell, long
What is the diameter ratio?”
The first one was moved was the warhead. The outside of the warhead was covered with a saddle-shaped elastic support. Under the support was an extra cylindrical wrap, and inside was a slender elastic core.
When the size of the core was used, everyone present was a little surprised.
Although I can't see the inside part, the exposed outside looks so slender and looks very skillful at first glance!
"At present, this is our limit." Qin Zhenhua said on the side: "The length and diameter are only 18."
On the 100mm rifled gun, the tail wing stable shell-piercing armor-piercing bullet made has an aspect ratio of 18. Now, on this 125mm gun, the same technology has been applied, and it is just that
It has achieved this level of 18.
Further increase requires further development of metallurgical technology, which is not achieved overnight, so the current 125mm shells have only achieved this level.
However, this was enough to surprise the other party.
Sure enough, after hearing the data of 18, the other party nodded with satisfaction: "No, it looks pretty good. The Soviets are said to not even reach 15. The depth of this is probably much higher than that of the Soviets."
