Ji Mingchu is a person who looks down on life and death, and has no interest in discussing his lifespan. He waved his hand and said, "No matter how many years I live, I hope to see the 98th steel developed sooner." Tell me, is there any way to get this steel out in three years? ”

"Three years?" Qin Hai repeated the time requirements given by Ji Mingchu, and began to quickly calculate in his heart.

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 formulation of the material. At present, the next generation of ultra-high-strength marine plate steel recognized abroad should be ultra-low-carbon bainite steel, in addition to controlling the carbon content below 7/10,000, it also involves the ratio of various elements such as manganese, niobium, vanadium, titanium, and aluminum. Each trace element has a specific role to play in steel, and the mechanism of these actions 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, what kind of oxygen absorber is used, how to cool, how to cast, each factor will affect the quality of steel, and ultimately determine the performance of the finished product.

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

The last aspect is rolling technology. The thickness of the ship plate steel ranges from 20 mm to 90 mm, and the armor plate used to build the aircraft carrier bridge is even up to 330 mm thick, which puts forward demanding requirements for the performance of the rolling mill. Due to the long-term lack of large-format thick plate rolling mills in China, ship plate steel can only be produced by die casting process, which 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 in the rolling process is also a technical imperative. About the change in grain structure during pressure processing. and the recovery and evolution process of dislocations, deformation zones, subcrystals, etc. in the deformed crystal after processing, etc., each of which is enough to write hundreds of articles to elaborate. As the core technical secrets of metallurgical enterprises, these articles have never appeared in academic journals, and they cannot be found to learn from them.

The United States, the Soviet Union, Japan, France and other countries have all been immersed in this field for many years and have accumulated countless experiences. China started late in the development of shipboard steel, and its investment has been limited. The foundation is very weak. In this case, it is difficult to break through the manufacturing bottleneck of No. 98 steel within three years.

Fortunately, Ji Mingchu met Qin Hai, a traverser who defended the sky, and with the help of Qin Hai's golden finger, the solution of these problems became easier. Qin Hai's metallurgical theories were more than 20 years ahead of this era, and could help researchers pierce layer after layer of window paper, so that they would not have to take many detours. In this way, as long as the investment can be guaranteed. Coupled with a good scientific research management mechanism, it is not difficult to achieve results in three years.

In just a short period of time, Qin Hai had thought through the whole thing clearly, and even where he needed to point out the clueless researchers, he also had a general framework. He smiled and said to Ji Mingchu: "This matter is difficult to say. It is easier said than done, depending on how determined the country can be. ”

Ji Mingchu said: "The determination of the country. You don't have to worry. I can tell you that no matter what conditions you need, the state can guarantee you...... Except for money! ”

"Poof!"

Qin Hai almost squirted a mouthful of blood onto Lao Ji's face. Old man, you have to be shameless, you can't come up with money, and you claim that any conditions can be guaranteed. Isn't that playing on me? Well, even if people are swordsmen, and I am donkey meat, can you not say this kind of righteous and awe-inspiring words?

Ji Mingchu also knew that his words were too laid-back, and he was rarely embarrassed for a few seconds. Then he said: "You also know that the country has no money now, and the army has no money. I heard from the Science and Technology Commission that you have the ability to get money, so I entrusted this matter to you. Steel is piled up with money, and I know this, but if there is a little other way, I can't bully you as young as I am, right? ”

"Elder Ji, don't say that, this makes me embarrassed." Qin Hai is also embarrassed, he is a revolutionary predecessor, and he really can't afford to apologize to himself like this. In fact, Ji Mingchu's answer was also expected by Qin Hai, the 70X Institute and the 43A factory were struggling because of lack of money, how strong could the navy be?

In fact, there are many talents in the field of military industry, and if Qin Hai throws away the aura of a traverser, he really can't find too much superiority in the military industrial system. Why can't people make No. 98 steel for so long, isn't it because of the problem of funding? If you don't have money, you can say Xiao Cai.

"Ji Lao, I agreed to this matter. No one dares to pack a ticket for such a thing as scientific research, so I won't give you a military warrant. But I promise that I will do my best to help the Navy complete the research and development of 98 steel within three years. Qin Hai said categorically to Ji Mingchu.

"Then on behalf of the whole army, I would like to express my gratitude to you." Ji Mingchu said solemnly.

Qin Hai raised his hand, stopped Ji Mingchu's words, and said, "Old Ji, I haven't finished my words yet. If I donate all the money of the Daqin Group to help the navy, it will be no problem to make No. 98 steel. But I guess you wouldn't want me to do that either, right? ”

"It doesn't have to be." Ji Mingchu said, "Although you are a capitalist, we are now past the era of fighting local tyrants, and the army cannot take advantage of you." ”

"Uh-uh, okay." Qin Hai replied in a sneering manner, as a capitalist, sitting in front of the senior generals of the people's army, he really felt a little trembling. He said: "You just said that no matter what conditions I need, the state can agree, so can I make an excessive demand?" ”

"You say, it's not too much, I'll evaluate it." Ji Mingchu said.

Qin Haidao: "I hope to be able to intervene in the country's rare earth strategy...... Forget it, it's really a matter of lifting some people up for strategy now, and to put it simply, I want to put the rare earths in my hands. ”

"Rare earths?" Ji Mingchu looked at Qin Hai in surprise, not knowing what Qin Hai wanted to say.

"That's right, rare earths." Qin Hai said, "As you know, our Daqin Group is engaged in materials, and we are engaged in new functional ceramics, strong magnet materials, special steels, etc., all of which need rare earths as raw materials. At present, the management of rare earths in China is extremely chaotic, and a large number of valuable rare earth resources flow abroad, while domestic enterprises like ours cannot get sufficient supply of rare earths. I have the courage to make such a request to Ji Lao, and hand over all the rare earths in the country to me to manage, what do you think? ”

After Ji retired at the beginning of the Ming Dynasty, he devoted a great deal of effort to the modernization of the army's equipment, and he was no stranger to scientific and technological problems. He is not as obsessed with the loss of rare earths as Qin Hai, but he also knows the value of rare earths. He pondered for a while and said: "As far as I know, many industries are in great need of rare earths, including the superalloys used in our army's aero engines, which also contain a large number of rare earth elements. If the country gives you all the rare earths, won't it make you stuck in the neck of the country? ”

Qin Hai said with a bitter face: "Elder Ji, do you think I look like a very unconscious person? The needs of the state, how could I possibly ignore them. What I want to do is to standardize the production of rare earths, improve the utilization rate of resources, and restore the original value of these resources, which are now being sold cheaply. If I want to get stuck in someone's neck, it's just a foreigner's neck. ”

"Really?" Ji Mingchu asked.

Qin Haidao: "You don't have to ask me like this, no matter how good my ability is, I don't dare to be an enemy of the country, right?" You can rest assured that when it comes to matters of national interest, I will not make the wrong choice. However, if someone deceives resources in the name of the state and sells them abroad without permission......"

"Then you sue me, and I'll kill him directly!" Ji Mingchu said confidently.

"Uh...... Isn't that too violent? Qin Hai smiled, "However, with Ji Lao's words, I am relieved." I can predict that once the rare earths are handed over to me to manage, Japan will definitely be the first country to jump out to protest, because the semiconductor manufacturing they are best at is closely related to rare earths, and I will definitely squeeze out the last bit of their profits. ”

"If that's the case, then I'm firmly behind you." Ji Mingchu patted the table lightly, "I don't believe in Sino-Japanese friendship." Between China and Japan, sooner or later there will be a war, and they still owe 20 million lives to the Chinese! ”

Ji Mingchu's words suddenly lit up the fire of anger in Qin Hai's heart, he stood up and said loudly: "Ji Lao, just say this to you, I will give you a military order now, how can you not get No. 98 steel within three years, I will see you!" ”

Ji Mingchu said with a smile: "Haha, there's no need to raise your head." If you can take out No. 98 steel within three years, I will give you a box of Moutai that I have treasured for 40 years, what do you think? ”

"I'm done." Qin Haiqing replied in high spirits.

"Rare earth matters, you go and write a report, write everything clearly about what you plan to do and how to deal with the relationship with the country, and I will help you hand it over." Ji Mingchu said.

"No problem, I'll write it when I get back, and I'll send it to you as much as possible." Qin Haidao, "In addition, regarding the current development status of No. 98 steel, please find someone to sort it out and provide it to me, so that I can put forward a solution in a targeted manner." ”

"Then we'll settle our minds." Ji Mingchu stood up and stretched out his hand to Qin Hai.

"It's a deal!" Qin Hai also stretched out his hand and held it tightly with Ji Mingchu. (To be continued......)
