Ji Mingchu was a person who looked down upon life and death and had no interest in discussing his own lifespan. [He waved his hand and said: "No matter how many years I can live, I hope to see No. 98 steel being developed sooner. Tell me about it."
, is there any way to make this kind of steel available within three years?”
"Three years?" Qin Hai repeated the time requirements given by Ji Mingchu and began to calculate quickly in his mind.
The manufacturing 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. Currently, the next generation of ultra-high-strength ship plate steel recognized abroad should be ultra-low carbon bainite steel. In addition to controlling the carbon content below 7 parts per 10,000, it also involves
To the ratio of manganese, niobium, vanadium, titanium, aluminum and other elements. Each trace element can play a specific role in steel, and the mechanisms of these effects need to be studied to determine the best ratio relationship.
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 deoxidizer is used, how to cool it, and how to cast it. Each factor will affect the quality of the 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 presence of manganese sulfide, oxides, carbides and other impurities will reduce the plasticity, toughness, etc. of the steel. For example, iron sulfide formed from sulfur will cause the steel to melt when heated.
Hot brittle cracks occur during rolling and welding. Technologies to ensure purity mainly include vacuum smelting and out-of-furnace refining, 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, and the armor plates used to build aircraft carrier bridges are even as thick as 330 mm. Such thick steel plates place stringent requirements on the performance of the rolling mill. .Due to the long-term lack of large-format thick plate rolling mills in our country, ship plate steel can only be produced using the die casting process. This is also a key reason that affects the strength of my country's ship plate steel.
In addition to the requirements of the rolling mill, temperature control during the rolling process is also a technical essential. Regarding the changes in the grain structure during pressure processing, as well as the recovery and evolution of dislocations, deformation bands, sub-grains, etc. within the deformed crystal after processing is completed.
Processes, etc., each item is enough to write hundreds of articles to explain. As the core technical secrets of metallurgical enterprises, these articles have never been published in academic journals, and there is no source for reference.
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 ship plate steel, and its investment has been limited. The foundation is very weak. In this kind of situation
Under such circumstances, it would be extremely difficult to break through the manufacturing bottleneck of No. 98 steel within three years.
Fortunately, at the beginning of the Ming Dynasty, Ji met Qin Hai, a time-traveler who defied the odds. With the help of Qin Hai's golden finger, it became easier to solve these problems. The metallurgical theory mastered by Qin Hai was more than 20 years ahead of this era, and he could
Help researchers break through layers of window paper, so that they don’t have to make 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 while, Qin Hai thought about the whole thing clearly. He even had a general framework on where to point out the clueless researchers. He smiled and said to Ji Mingchu:
"This matter is difficult to say. Easy to say. It depends on how determined the country is."
Ji Mingchu said: "The country is determined. You don't have to worry. I can tell you this, no matter what conditions you need, the country can guarantee you... except money!"
"puff!"
Qin Hai almost spit a mouthful of blood into Lao Ji's face. Old man, you are so shameless and can't provide money, yet you claim that you can guarantee all conditions. Isn't this just kidding me? Well, even if you are a knife-edge person,
, I am donkey meat, can you not say this so righteously?
Ji Mingchu also knew that his words were too shameless. He was 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 the money.
, that’s why I entrust this matter to you. Steel is piled up with money. I also know this. As long as there is some other way, I can’t bully a young person like you, right?
no?"
"Mr. Ji, please don't say that. It makes me feel ashamed." Qin Hai was also embarrassed. He was a revolutionary senior after all, and he couldn't afford to apologize to him in such a lowly manner. In fact, Ji Mingchu's answer was the same
As expected by Qin Hai, Factory 70x and Factory 43a were all struggling because of lack of money. How strong could the navy be?
In fact, there are a lot of talents in the military industry. If Qin Hai throws away his aura as a time traveler, he really won’t find much sense of superiority in the military industry system. Why people can’t produce No. 98 steel for so long? In the final analysis, it’s not because of funding.
What's the problem? If you don't have money, just call Xiao Cai.
"Mr. Ji, I have agreed to this matter. No one dares to guarantee this kind of 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 this matter.
Complete the research and development of No. 98 steel within three years." Qin Hai told Ji Mingchu categorically.
"Then on behalf of the entire 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: "Mr. Ji, I haven't finished speaking yet. If I donate all the money of the Daqin Group to help the navy, there will be no problem in producing No. 98 steel. However,
I don’t think you want me to do this, right?”
"That's not necessary." Ji Mingchu said, "Although you are a capitalist, we have passed the era of fighting local tyrants, and the army cannot take advantage of you."
"Uh-huh, okay." Qin Hai replied indifferently. As a capitalist, sitting in front of senior generals of the People's Army, he really felt a little trepidatious. He said: "You just said that no matter what conditions I need,
The country can agree to it, so can I make an excessive request?"
"You tell me, whether it's too much or not, let me judge." Ji Mingchu said.
Qin Haidao: "I hope to be able to intervene in the country's rare earth strategy...Forget it, mentioning the strategy now is really flattering some people. To put it simply, I hope that the rare earths will be managed by me."
"Rare earth?" Ji Mingchu looked at Qin Hai in surprise, not knowing what Qin Hai wanted to say.
"Yes, it's rare earths." Qin Hai said, "As you know, our Daqin Group is engaged in materials. Our new functional ceramics, strong magnet materials, special steels, etc. all require rare earths as raw materials. At present, domestic
The management of rare earths in the country is extremely chaotic, and a large amount of precious rare earth resources flow abroad. However, domestic enterprises like ours are unable to obtain sufficient supply of rare earths. I boldly made such a request to Mr. Hebei, and handed over the management of all rare earths in the country to me.
What do you think?"
After Ji Mingchu retired, he devoted a lot of effort to the modernization of military equipment and was no stranger to technological issues. He was not as worried about the loss of rare earths as Qin Hai was, but he also knew the value of rare earths. He pondered.
After a while, he said
: "As far as I know, many industries are in great need of rare earths, including the high-temperature alloys used in our military's aeroengines, which also contain a large amount of rare earth elements. If the country hands over all the rare earths to you, wouldn't that make you stuck?
The neck of the country?"
Qin Hai said with a bitter face: "Mr. Ji, do you think I am a very ignorant person? How could I ignore the needs of the country? What I want to do is to standardize the production of rare earths, improve resource utilization, and let
These resources that are now being sold at low prices have regained their original value. If I want to choke anyone's neck, it is only the neck of foreigners."
"Really?" Ji Mingchu pressed.
Qin Haidao: "You don't have to ask me like this. No matter how capable I am, I wouldn't dare to be an enemy of the country, right? Don't worry, I will never make the wrong choice when it comes to national interests. However, if someone pretends to be a country
In the name of defrauding resources and selling them abroad privately..."
"Then just tell me and I will kill him directly!" Ji Mingchu said confidently.
"Uh...isn't this too violent?" Qin Hai said with a smile, "However, I am reassured by Mr. Ji's words. I can predict that once rare earths are handed over to me to manage, Japan will definitely be the number one
A country that jumped out to protest, because the semiconductor manufacturing they are best at is closely related to rare earths, I will definitely squeeze out every last bit of profit they have."
"If that's the case, then I will firmly support you." Ji Mingchu patted the table lightly, "I don't believe in Sino-Japanese friendship. Sooner or later, there will be a war between China and Japan, and they still owe the Chinese people 20 million
Where is the human life!"
Ji Mingchu's words suddenly ignited the fire of angry youth in Qin Hai's heart. He stood up and said loudly: "Mr. Ji, just for these words, I will issue a military order to you now."
"Why can't we produce No. 98 steel within three years? I'll see you!"
Ji Mingchu said with a smile: "Haha, there is no need to mention it. If you can come up with 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 ready to drink it." Qin Hai responded with high spirits.
"On the rare earth matter, you write a report. Write it all clearly about what you plan to do and how to deal with the relationship with the country. I will hand it over for you." Ji Mingchu said.
"No problem, I'll write it when I get back and send it to you as soon 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 propose a targeted solution.
Ideas.”
"Then let's make it a deal." 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, please search Piaotian Literature for better and faster novels!
