Regarding the new type of gun steel, Liu Yijiu began to consider which type of gun steel should be taken out when he had the idea of ​​building a tank.

At present, countries around the world are studying new gun steel. Although the old-fashioned tungsten alloy steel has a high hardness and excellent high temperature resistance, it is also very good because of its high hardness and low toughness. After multiple shots, the gun barrel will gradually reach the maximum metal fatigue strength due to the instant high temperature and high pressure generated when the gun is out of the bore.

In this way, when the barrel service life is reached, the barrel must be replaced, otherwise something will easily happen.

The Republic has always attached great importance to the development of artillery, and there is no way to change it in a short period of time. Without a powerful air force and navy, the land kings like tanks must be created.

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, destined that tanks have very high requirements for reliability indicators of gun barrels and turrets, which makes the materials for producing these components higher. The tank guns of the third generation tanks are generally chromium, nickel, molybdenum, and tungsten alloy steel. After entering the 21st century, tank gun steels in the Republic generally use 25cr3 3ninb.

Liu Yijiu was also preparing to use this material at the beginning because it has better performance than PCI3 and 32ci3 and 32ci3 and 44 steel. However, what he learned about in Factory 2983 these days made him a little depressed.

There is no ability to develop this new material at all!

This is a problem he ignored at the beginning.

"What do you mean is that if you want to create new cannon steel materials, you must return to our base or other materials research units?" Zheng Hao was speechless about Liu Yijiu's opinion.

He has been busy strengthening the quality awareness of factory cadres and employees these days. Liu Yijiu discussed the research plan for new materials with Tian Deming and others. He had to at least let the entire factory run again before leaving.

"Yes. There is only production capacity here, but no scientific research capacity at all. When we go there, we only have R&D capacity and do not have much production capacity. Therefore, if we want to develop new-style gun steel, we must return to our base..." Liu Yijiu nodded seriously.

Just have production capacity here.

After the research at the Ninth Institute is completed, the material formula and production process will be directly handed over to Factory 2983 for production.

There is no need to waste a lot of manpower, material resources and funds. Otherwise, it will eventually cause serious waste due to repeated construction, which is a disaster for the republican system, which is about to carry out large-scale disarmament and reduce military expenditures.

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

Could it be that this kid bragged at the beginning and wanted to return to the base and hide when he was worried that he would be exposed?

"No problem. But you have to ask for something from the top..." Liu Yijiu nodded and said to Zheng Hao with a smile. Anyway, it's Zheng Hao's business.

Hearing this, Zheng Hao suddenly felt bitter, "Don't let me ask for things. The last time I asked for someone, the leaders of the entire capital knew about it. Minister Liu had said he would deal with me. I didn't dare to see him now, otherwise, I wouldn't drag it until he left before I could get here..."

This matter cannot be done any more.

There is no problem once, but twice or three times, you have to be killed by Minister Liu. You still hope to be promoted and climb to a higher position to contribute to the national defense industry? That's a dream.

"Don't worry, I won't let you take the bedding roll this time. Didn't Master Jia from our second zone have made a new model of high-temperature alloy? After performance testing, it is much better than the one currently used, right? You take this to him and ask him for credit, and then take the opportunity to complain. The research in our hands cannot continue... Then he will ask why, and you will tell him directly. We lack rare earth elements, so we must allocate two units to us, and at least two units must 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 important effect on ours?" Zheng Hao didn't know the technology at all, and only knew about the materials, such as steel and aluminum, and various models, let alone rare earths.

"I can't explain this thing to you. Just go and ask for it. I promise he will agree, because there are so many things in our country..." Liu Yijiu said very easily.

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

"What are you doing? If you don't believe it, wouldn't you just ask a few people for some inquiries? The heavy rare earths in Ganzhou and the light rare earths in Inner Mongolia are all needed. It's best to allow him to allocate two production units to us in these two places..." Liu Yijiu took this opportunity to save the rare earth resources of the Republic.

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

After the reform and opening up of the Republic, in order to obtain more foreign exchange, foreign countries also needed a lot of resources that they lacked, especially the Japanese. They did not produce this thing at all in China, so they desperately imported it from the Republic and hoarded it.

The Republic lacks understanding of rare earth resources, and most of them are privately mined and randomly, and then for more orders, they start to sell them to the Japanese.

The Japanese advanced electronics industry can even be said to be based on the cheap provision of rare earth resources in the Republic. By the time the Republic discovered that this thing was too useful, domestic rare earth resources were almost sold.

Especially the light rare earth elements in Inner Mongolia have very special uses in aerospace, especially missile satellite guidance, so they began to pay attention to it. At that time, the Japanese and smart Americans did not know how much they had hoarded.

Especially some elements here are produced in the Republic.

Liu Yijiu is here, so they can't take advantage of this.

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

Only when the country recognizes the importance of rare earth elements can we not export these strategic resources such as pitiful large-scale foreign exchange exports for that little bit of poor foreign exchange.

Before private domestic companies entered the mining industry, Liu Yijiu still had ten years to use.

This is enough.

It seems that this thing is not very important, and Zheng Hao also thinks that Liu Yijiu is not lying to him. Anyway, he thinks that the larger the scope of the management of the Ninth Hospital, the better, so that he can climb to a higher position in the future.

"It's very simple to be sure?" Zheng Hao felt that this matter was not so easy.

Otherwise, Liu Yijiu would not let him come forward.

"I said to the leader, can you give your subordinates a little bit of the minimum trust? This matter is really very simple. You can even just call Minister Liu. Can we communicate happily?" Liu Yijiu was speechless.

Very speechless.

Isn’t it just to ask for raw material production units that two countries do not pay attention to at all!

Moreover, in this era, the country did not pay much attention to the production of rare earths, and this thing was useless to the Republic.

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

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

Zheng Hao finally agreed. Anyway, he was calling. He just threw the phone aside when the leader scolded him. He just picked it up after the leader finished scolding him.

Liu Yijiu ignored Zheng Hao and returned to the technical room in Factory 2983 to continue drawing pictures of the Type 87 82mm mortar.

Knowing his fault, Zheng Hao asked Tian Deming to arrange two draftsmen for Liu Yijiu to help Liu Yijiu with special help. As for various technical requirements and performance requirements, Liu Yijiu was too lazy to write them. While he said that, he asked the two draftsmen to record them.

Luo Tong, an unlucky child, was sent to the base as soon as Zheng Hao arrived here. The base's production task is now tight and he needs to go to the workshop to supervise quality issues.

The quality accident in Factory 2983 sounded a wake-up call for production units in the military system across the country, especially the department in charge of the weapons industry of the Fifth Machinery Department, which strictly required subordinate units to comprehensively check quality problems and prevent the occurrence of things that require production but not quality again.

After the Type 87 mortar was completed, Liu Yijiu threw it to Tian Deming. Whether Tian Deming would ask the production department to get the test samples out? With Zheng Hao here, Liu Yijiu didn't need to worry about it.

Anyway, the material requirements of the Type 87 mortars are not as high as those of heavy artillery and tanks. The original materials will not be problematic as long as they are carefully implemented according to the process flow. The cannons that were supported to monkeys did not have these problems.

According to Liu Yijiu's suggestion, Zheng Hao told those responsible for quality inspection and technical personnel that they would draw some cannons from each batch of products in the future, so that they would fire their cannons when they are fine!

If these people could not take quality seriously as before, they would have no choice but to send them to the front line to be artillery soldiers.

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

This was the first time he had seen such a young man, who was very familiar with materials, craftsmanship, design, production technology, heat treatment and other series. Most of the workers, peasants and soldiers who were assigned to their factory were slags and were useless... (To be continued...)

ps: It was already four o'clock after finishing writing this chapter, but for the sake of what my brothers read in the morning, Hulu's hands cramped and still insisted on it.

The comments in each chapter are asking for monthly tickets. I hope that my brothers will reward Hulu with the hard work of Hulu.
Chapter completed!
