Super military empire

Regarding the new type of gun steel, Liu Yijiu was thinking about which gun steel should be used from the time he had the idea to build a tank.

At present, all countries in the world are studying new gun steel. Although the old-fashioned tungsten alloy steel has high hardness and excellent high temperature resistance, it has been shot many times due to its high hardness and low toughness. After that, the barrel will gradually reach the maximum metal fatigue strength due to the instant high temperature and pressure generated when the gun is ejected from the bore.

In this way, when the service life of the barrel is reached, the barrel must be replaced, otherwise accidents will easily occur.

The Republic has always attached great importance to the development of artillery, and there is no way to change it in a short time.In the absence of a powerful air force and navy, tanks, the king of the land, must also be developed.

Tanks are actually a mobile artillery, but tank guns have higher requirements for materials!The harsh combat environment, far higher chamber pressure and temperature than ordinary artillery, doomed the tank to have very high requirements for the reliability of the barrels and turrets of the barrel parts, which makes the material requirements for the production of these parts also high. Go up.The tank guns of the third-generation tanks are generally made of alloy steel of chromium, nickel, molybdenum, and tungsten. After entering the 21st century, the steel of tank guns in the Republic of China is generally made of 25cr3mo3ninb.

Liu Yijiu also prepared to use this material at the beginning, because it has better various properties than the two gun steels, pcrni3mov steel and 32crni3mov steel.But what he learned in the 2983 factory these days made him a little depressed.

There is simply no ability to develop this new material!

This was a problem he ignored at the beginning.

"What do you mean is that if you want to develop new gun steel materials, you have to go back to our base or another material research unit?" Zheng Hao was quite speechless about Liu Yijiu's opinion.

He is busy enhancing the quality awareness of factory officials and workers these days, and Liu Yijiu discusses research plans for new materials with Tian Deming and others.He can at least leave after the entire factory is back up and running.

"Yes, there is only production capacity here, but no scientific research capacity at all. When we go there, there is only research and development capacity, not much production capacity. Therefore, if we want to develop new gun steel, we must return to our base... …" Liu Yijiu nodded solemnly.

Just have production capacity here.

At that time, after the research has been done in the Ninth Institute, the material formula and production process will be directly handed over to the 2983 factory for production.

There is no need to waste a lot of manpower, material resources and funds.Otherwise, serious waste will be caused in the end due to repeated construction, which is a disaster for the Republic’s military industry system, which is about to undergo large-scale disarmament and cut military expenditures.

"Are you really sure about this?" Zheng Hao asked Liu Yijiu uncertainly.

Isn't it because this kid bragged at the beginning and wanted to go back to the base to hide because he was worried about being punctured?

"No problem. But you have to ask for something from above..." Liu Yijiu nodded and said to Zheng Hao with a little smile.Anyway, everything is Zheng Hao's business.

Hearing this, Zheng Hao suddenly felt bitter, "Don't let me ask for things. The leaders of the entire capital knew about the important person last time. Minister Liu said he wanted to clean up me. I see him now. I don’t dare, otherwise, I won’t be here until after he leaves this time..."

This thing cannot be done anymore.

Once there is no problem, but twice, three times, you have to be cut to death by Minister Liu, and hope to be promoted to a higher position to contribute to the defense industry?That is dreaming.

"Don't worry, I won't let you go with the blanket again this time. Didn't Master Jia of our second district have already made a new model of superalloy? After performance testing, it is much better than the current one, right? You? Take this to ask him for credit, and then take the opportunity to complain, the research in our hands can no longer continue... Then he will ask why, you directly tell him that we lack rare earth elements in our hands, and we must allocate two units to us , At least let two units provide us with a steady stream of rare earth elements..." Liu Yijiu gave Zheng Hao an idea.

"Rare earth elements? What is this? Does it have a very big effect on us?" Zheng Hao doesn't understand technology at all, and he knows materials such as steel, aluminum, and various models. Not to mention rare earths.

"I can't explain this thing to you, you just have to go. I promise he will agree, because there are so many things in our country that can't do it..." Liu Yijiu said easily.

"You didn't lie to me?" Zheng Hao had already been fooled by Liu Yijiu.

"What are you doing! If you don’t believe me, wouldn’t you just ask a few people? Both the heavy rare earths in Jiangxi province and the light rare earths in Inner Mongolia. It’s better to let him allocate two places in these two places. The production unit gives us..." Liu Yijiu took this opportunity to save the rare earth resources of the Republic.

The rare earth resources of the Republic have the most proven reserves and the richest types in the entire world.Then, it is very difficult to study this thing, and the Republic itself has not made much progress in this research. The countries that have studied this thing most are the United States, Germany, and Japan, which have always developed industries.

After the reform and opening up of the Republic, in order to obtain more foreign exchange, foreign countries also needed a lot of these resources they lacked, especially the little devils. They did not produce this stuff at all, so they desperately imported from the Republic and hoarded them.

In the Republic, there is insufficient knowledge of rare earth resources. Most of them are private mining and random mining, and then for more orders, they began to bargain with each other and sell them to the Japanese.

The Japanese advanced electronics industry can even be said to be built on the cheap supply of rare earth resources in the Republic.By the time the Republic finds that this gadget is too useful, the domestic rare earth resources have almost been sold.

Especially the light rare earth elements in Inner Mongolia, when they have very special uses in aerospace, especially the satellite guidance of missiles, they began to pay attention. At that time, little devils and savvy Americans did not know how much they had hoarded.

Especially some of the elements in it are only produced by the Republic.

When Liu Yijiu is here, they don't want to take advantage of this.

This is also the reason why he has to produce materials that were only produced by the Republic in the 21st century in this era!

Only when the country realizes the importance of rare earth elements, can it not export these strategic resources on a large scale for that pitiful foreign exchange.

Liu Yijiu still had ten years to use before private domestic entry into the mining industry.

This is enough.

Feeling that this thing doesn't seem to be important, Zheng Hao also feels that Liu Yijiu doesn't seem to lie to him. Anyway, he thinks that the larger the scope of the management of the Ninth Institute, the better, and that he can climb to a higher position in the future.

"Sure it's very simple?" Zheng Hao felt that this matter was not so easy.

Otherwise, Liu Yijiu would not let him come forward.

"I said, the leader, can you give your subordinates a little bit of trust? This is really very simple. You can even call Minister Liu directly. Can we still communicate happily?" Liu Yijiu suddenly Speechless.

Very speechless.

Doesn't it mean raw material production units that the two countries simply don't pay attention to!

Moreover, in this era, the country has not paid much attention to the production of rare earths. This thing is of no use to the Republic.

"Last time you told me that there would be no problem..." Zheng Hao reminded Liu Yijiu.

"I also said about the consequences last time..." Liu Yijiu didn't want to continue talking with Zheng Hao.

Zheng Hao finally agreed, anyway, call it anyway, just throw the phone aside when the leader scolds himself, and pick it up after the leader finishes scolding.

Liu Yijiu ignored Zheng Hao and went back to the technical room in the 2983 factory to continue drawing the 87-type 82mm mortar.

Knowing his problem, Zheng Hao obliquely asked Tian Deming to arrange two draftsmen for Liu Yijiu.He specially helped Liu Yijiu to set the drawing standards. As for various technical requirements and performance requirements, Liu Yijiu was too lazy to write. While he said, he asked the two draftsmen to record it.

The hapless boy Luo Tong, Zheng Hao was sent to the meeting base as soon as he arrived here. The production task of the base is now tight and he needs to go to the workshop to monitor quality issues.

The quality accident in the 2983 factory has sounded the alarm for the production units of the military industry system across the country, especially the department in charge of the ordnance industry of the Fifth Machinery Department. It happened again.

After the 87 mortar was finished, Liu Yijiu threw it to Tian Deming. Whether Tian Deming would let the production department get the test samples out, Zheng Hao was here, so Liu Yijiu didn't need to worry about it.

Anyway, the 87-type mortar has lower material requirements than those of heavy artillery and tanks. As long as the original materials are carefully implemented in accordance with the process, there will be no problem.The artillery used to support the monkeys did not have these problems.

According to Liu Yijiu's suggestion, Zheng Hao told those responsible for quality inspection and technology that in the future, some cannons will be taken out of each batch of products at will, so that they can play the cannons if nothing happens!

If these people can still ignore quality as before, they will have no choice but to send them to the front as artillery.

Tian Deming was a little disappointed with Liu Yijiu's departure. If this young man stays in this factory, the production and technology research and development of the 2983 factory will be faster.

This is the first time he has met such a young man, who is very familiar with materials, crafts, design, production technology, heat treatment, etc.Most of the workers, peasants, and soldiers in their factory who were later assigned are scum, which is unbearable...
