Material Empire

At the beginning of Ji Ming, he was a bearish person, and was not interested in discussing his life. He waved his hand and said, "No matter how many years I can live, I hope to see steel No. 98 be developed earlier. Tell me, is there any way to make this steel come out within three years?"

"Three years?" Qin Hai repeated the time requirements given by the early Ming Dynasty and began to calculate quickly.

The manufacture of ultra-high-strength ship plate steel mainly involves four aspects of technology:

The first is the design of the metallurgical chemical composition of the steel, that is, the formula of the material. At present, the next-generation ultra-high-strength ship plate steel recognized abroad should be ultra-low-carbon bainite steel. In addition to controlling the carbon content below 7 ten thousandths, it also involves various elements such as manganese, niobium, vanadium, titanium, and aluminum. Matching. Each trace element can play a specific role in steel, and the mechanism of these effects needs to be studied to determine the best ratio.

The second aspect is the control of the smelting process. What kind of molten iron is used, what smelting temperature is used, which deoxidizer is used, how to cool, how to cast, each factor will affect the quality of the steel, and ultimately determine the performance of the finished product.

The third is purity control. Because of the content of sulfur and phosphorus, and the presence of impurities such as manganese sulfide, oxides, carbides, etc., it will reduce the plasticity, toughness and so on of the steel. For example, iron sulfide formed from sulfur can cause hot brittle cracks in steel during hot rolling and welding. Technologies to ensure purity include vacuum smelting and refining outside the furnace, etc. These technologies also need to be explored.

The last aspect is rolling technology. The thickness of ship plate steel ranges from 20 mm to 90 mm. The armor plates used to build aircraft carrier bridges are even 330 mm thick. Such thick steel plates place stringent requirements on rolling mill performance. Due to China's long-term lack of large-scale thick plate rolling mills, ship plate steel can only be produced by die casting process. This is also a key reason affecting the strength of ship plate steel in China.

In addition to the requirements of the rolling mill, temperature control during rolling is also a technical point. Regarding the changes in the grain structure during pressure processing, and the recovery and evolution of dislocations, deformation bands, and sub-crystals in deformed crystals after processing, each of them is enough to write hundreds of articles to explain. As the core technology secrets of metallurgical enterprises, these articles have never been seen in academic journals, and no source can be found for reference.

The United States, the Soviet Union, Japan, and France have soaked in this field for many years and accumulated countless experiences. China started late in the development of ship plate steel. Coupled with limited investment, the foundation is very weak. under these circumstances. If you want to break through the bottleneck of No. 98 steel in three years, it will be difficult.

Fortunately, in the early Ming Dynasty, he met Qin Hai, a transcendent rider, with the help of Qin Hai's golden finger. Solving these problems becomes easy. Qin Hai's metallurgical theory is more than 20 years ahead of this era, which can help researchers break through layers of window paper so that they don't have to take detours. In this way, as long as the investment can be guaranteed and a good scientific research management mechanism, it is not difficult to achieve results in three years.

In just a few minutes, Qin Hai thought about the whole thing, and even needed to call some clueless researchers. He also had a rough frame. He smiled and said to Ji Mingchu: "This is difficult to say. It is easy to say, it depends on how determined the country can be."

Ji Mingchu said: "You don't have to worry about the determination of the country. I can tell you this way, no matter what conditions you need, the country can guarantee you ... except money!"

"puff!"

Qin Hai almost sprayed a bite of blood on Lao Ji's face. Old man, you have to be shameless. Can not afford the money, and claimed that all conditions can be guaranteed. Isn't this playing with me? Well, even if the man is a sword, and I am a donkey, can you not say such a big thing?

At the beginning of the Ming Dynasty, he also knew that what he said was too skinny. He was embarrassed for a few seconds, and then said, "You also know that the country has no money now, and the military has no money. I heard the Commission of Science and Technology said that you have the money That ’s why I entrust this matter to you. I know that steel is piled up with money, but if there is another way, I ca n’t bully you as a young man, yes No? "

"Ji Lao, don't say that, it makes me feel complacent." Qin Hai is also embarrassed. People are anyway a revolutionary predecessor, so I apologize to myself, I can't afford it. In fact, the answer from the early Ming Dynasty was also expected by Qin Hai. The 70x and 43a factories are struggling because they have no money. Where can the Navy go?

In fact, there are a lot of talents in the military industry field. If Qin Hai abandons the aura of the passerby, he won't find much sense of superiority in the military system. Why can't people make steel No. 98 for so long? Isn't it because of funding? If you do n’t have the money, you can talk about Xiao Cai.

"Ji Lao, I agreed to this matter. No one dares to pack tickets for scientific research, so I will not give you a military order. But I promise that I will do my best to help the Navy in The development of No. 98 steel was completed within three years. "Qin Hai said decisively to the beginning of Ji Ming.

"Then I would like to thank you on behalf of the entire army." Ji Ming said solemnly.

Qin Hai raised his hand and stopped the words of Ji Mingchu, saying, "Ji old, I haven't finished my words. If I donate all the homes of the Daqin Group to help the navy, it will be no problem to produce steel No. 98. But, I don't think you want me to do that, do you? "

"It doesn't have to be." Ji Ming said at the beginning, "Although you are a capitalist, we have passed the age of fighting local tyrants, and the army cannot take advantage of you."

"Uh, okay." Qin Hainei answered, as a capitalist, sitting in front of the senior generals of the People's Army really felt a little trembling. He said: "You said just now that no matter what conditions I need, the country can agree, so can I make an excessive request?"

"You say, it's not too much, let me evaluate." Ji Mingchu said.

Qin Haidao: "I hope to be able to intervene in the country's rare earth strategy ... forget it, now that the strategy is really uplifting to some people, let's just say, I hope to leave the rare earth to me to manage."

"Rare earth?" Ji Ming looked at Qin Hai in surprise at the beginning of the Ming Dynasty, wondering what Qin Hai wanted to say.

"Yes, it is rare earth." Qin Hai said, "You know, our Daqin Group is engaged in materials. The new functional ceramics, ferromagnetic materials, special steels, etc. we engage in require rare earth as raw materials. At present domestic The management of rare earths is extremely confusing, and a lot of precious rare earth resources are flowing abroad, but domestic companies like us cannot get sufficient rare earth supplies. I dare to make such a request to Ji Lao and leave all the rare earths in my country to manage. What do you think? "

After retiring at the beginning of the Ming Dynasty, he devoted a lot of effort to the modernization of military equipment and was no stranger to scientific and technological issues. He is not as concerned about the loss of rare earths as Qin Hai, but also knows the value of rare earths. He groaned for a while and said, "As far as I know, rare earths are very much needed in many industries, including the superalloys used in our military ’s aircraft engines, which also contain a lot of rare earth elements. If the country gives you all rare earths, Wouldn't it have stuck your country's neck? "

Qin Hai said bitterly: "Ji Lao, do you look like a very unconscious person? How can I ignore the needs of the country? What I want to do is to regulate the production of rare earths, improve resource utilization, These resources, which are now being sold cheaply, have been restored to their original value. If I want to stick to the neck of anyone, it is only the neck of a foreigner. "

"What is it?" Ji Ming asked at the beginning.

Qin Haidao: "You don't have to ask me like this, no matter how great I am, I dare not be hostile to the country? Don't worry, I will not make the wrong choice when it comes to matters of national interest. However, if someone borrows the country Under the name, to defraud the resources to be sold abroad without authorization ... "

"Then you tell me, I directly hit him!" Ji Ming said vigorously at the beginning.

"Eh ... isn't this too violent?" Qin Hai laughed. "However, with the old phrase of Ji, I'm relieved. I can predict that once you hand over the rare earth to me for management, Japan will definitely be the first A country that has jumped out of protest, because the semiconductor manufacturing they are best at is closely related to rare earths, and I will definitely squeeze out their last bit of profit. "

"If this is the case, then I will firmly support you." Ji Ming patted the table lightly in the beginning, "I don't believe in China-Japan friendship. There is still a battle between China and Japan, and they still owe 20 million Chinese people. Human life! "

At the beginning of the Ji Ming period, he suddenly lighted the angry fire in Qin Hai's heart. He stood up and said loudly, "Ji old, just say this to you. I will give you a military order now. , How can you not get the 98 steel in three years ~ www.novelmtl.com ~ I will see you first! "

Ji Mingchu said with a smile: "Haha, you don't have to raise your head. If you can take out 98 steel within three years, I will send you a box of Maotai that I have treasured for 40 years. What do you think?"

"I'm sure." Qin Hai responded with high emotions.

"You need to write a report about the rare earth matters, and explain how you intend to do it and how to handle the relationship with the country. Please write everything clearly, and I will help you pass it on." Ji Mingchu said.

"No problem, I'll write it when I go back and send it to you as soon as possible." Qin Haidao, "In addition, I would like to ask someone to sort out the current development status of No. 98 steel and provide it to me so that I can propose a solution in a targeted manner. Ideas. "

"Then let's just say one thing." Ji Mingchu stood up and reached out to Qin Hai.

"One word is for sure!" Qin Hai also stretched out his hand, holding tightly with Ji Ming early. (To be continued)
