Qin Zhenhua's demeanor?

Of course Qin Zhenhua knew what the other party was talking about, since Qin Zhenhua entered a machine factory, it was a blockbuster, as an apprentice, relying on his own strength, he forcibly increased the power of the armor-piercing bullet a lot, so that the entire army was moved, and even relied on this achievement to correct his father's name, and after that, he 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, and under the leadership of his subordinates, one project after another has been developed, which is jaw-dropping and envious.

Even, it was because of Qin Zhenhua that a more important decision was made, called young people in charge! All factories should vigorously promote young people, because young people are full of vitality, young people are thoughtful and enterprising, and most of the old people are self-contained and conservative.

Qin Zhenhua completely set off a wave, and on the side of the Second Machine Factory, this young man named Rong Qiang, although he only entered the factory last year, but after coming in, he continued to show his edge.

It took a year to master the most sophisticated process of the Second Machine Factory: the opening of the gun chamber.

The second machine factory is to make artillery, there are many steps to make artillery, first of all, the smelting of cannon steel, this special alloy, is obtained by secondary smelting in the second machine factory, and then, in the blank, first open a hole, and then expand this hole, it becomes a gun barrel, and then the body tube is self-tightening, and then if it is a rifled gun, there must be a rifling step, and others, as well as the process of chrome plating inside the gun barrel, etc., in short, these processes are quite complex, but the most important of them is the hole.

The length of the barrel is several meters, and a small hole is opened on it, and the accuracy of this hole directly determines the accuracy of this cannon, even in the second machine factory, there are no more than twenty skilled masters, Rong Qiang is simply a genius, and he quickly mastered this craft.

Moreover, after discovering that the process of the thermal sheath of the barrel had not yet been perfected, he pondered it alone after work, and after wasting a few sets of aluminum, he actually made it out!

This made the factory quite excited, and at the end of the year, the factory also gave Rong Qiang an additional year-end reward.

Hearing the deeds of this young man, Qin Zhenhua immediately became interested: "Yes, when I have time, let me meet this young man." ”

Hearing Qin Zhenhua's words, Xie Huimin suddenly became vigilant: "This, you have to say it in advance, Rongqiang is from our Second Machine Factory, don't have any ghost ideas." ”

Obviously, the incident during the Chinese New Year has spread, a group of workers in the Red Star Electromechanical Factory went to a machine factory to make trouble, as a result, Qin Zhenhua only used one meal, a meal full of meat pieces, to buy these workers, 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 machine factory.

It is said that later, the director of the Red Star Electromechanical Factory went to the capital to make a big fuss, and I don't know what the result was.

Red Star Electromechanical Factory suffered such a big loss, even if it is crippled, the future fate is conceivable, and now, Xie Huimin almost regretted telling Qin Zhenhua about these things, what if Qin Zhenhua fell in love and dug this person into their first machine factory?

When the time comes, Rong Qiang said that he was leaving, and everyone couldn't stop him.

Qin Zhenhua smiled: "Lao Xie, what you said seems to be like I like to dig other people's corners, it's really boring, as long as this young man can make us cannons and advanced cannons, isn't he still helping us with a machine factory?" ”

Xie Huimin relaxed at this time, this is true, the second machine factory and the first machine factory are brother units, the second machine factory makes artillery, the first machine factory makes vehicles, and the second machine factory provides parts and components to the first machine factory, if they poach people from themselves, it will be too much to say.

The moment the two were talking, the guests from the old bus over there had already been around the fort and watched 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?" ”

"Absolutely." Xie Huimin said: "Our gun, is currently undergoing preliminary testing, the first few guns, has been tested chamber pressure, this tank gun, the current measurement results, it can withstand stable chamber pressure, at about 470 megapascals." ”

The tests were carried out little by little, just like our own 120 mm tank gun, after repeated tests, the chamber pressure has stabilized to about 560 megapascals, while our own 125 mm tank gun, in the initial tests, increased little by little, only to about 470 megapascals.

Even so, it is already very good, because the Soviets export the 2A46 tank gun, the chamber pressure is only about 450 megapascals, and the current test chamber pressure has exceeded the Soviets' tank gun!

"This data, very good, has surpassed the T-72." Parker said.

Everything is compared with the T-72, as long as it is higher than the T-72.

Then, under their gaze, the shells were moved out of the ammunition box on the side, and when they saw the shells, the people of Lao Ba's inspection group immediately opened their eyes again: "This, this shell, what is the aspect ratio?" ”

The first thing to move is the warhead, the outside of this bullet is covered with a saddle-shaped butt, under the butt, is an additional cylindrical package, inside is a slender bullet core, when looking at the size of this bullet core, everyone present is a little surprised.

Although you can't see the inside part, the outside is exposed, and it already looks so slender, and it looks very horizontal at first glance!

"At the moment, this is already our limit." Qin Zhenhua said on the side: "The length and diameter ratio can only be 18 for us."

On the 100 mm rifled gun, the side dug deep into the potential and made a tail stabilized shelling armor-piercing projectile with a length-diameter ratio of 18, and now, on this 125 mm gun, the same technology has been applied, and it has only achieved the level of 18.

Further increase requires further development of metallurgical technology, which is not achieved overnight, so the current 125-mm artillery shells have only achieved this extent.

However, this is enough to surprise the other party.

Sure enough, after hearing the data of 18, the other party nodded with satisfaction: "Yes, it looks good, the Soviets, it is said that they can't even reach 15, and this penetration depth should be much higher than that of the Soviets." ”
