Sanlian Iron & Steel Group. Pen, fun, and www.biquge.info

In the steelmaking control room, Chen Sanlian was accompanied by several people, the first of which was about the same age as Chen Sanlian, wearing a pair of black-framed glasses.

This is Ding Huixian, a senior researcher at the Provincial Iron and Steel Research Institute, and Chen Sanlian's college classmate, after graduating from university, Chen Sanlian chose to start a business, and is now the CEO of this steel company with an annual output value of billions. Ding Huixian, on the other hand, has been engaged in scientific research and is now a senior researcher at the Provincial Iron and Steel Research Institute.

Ding Hui first undertook the research of a national topic, the smelting technology of a high-strength steel, which may be the relationship between the two college classmates, Ding Hui first brought his team to Sanlian Iron and Steel Group, where scientific research and experiments were conducted.

Through the large glass of the control room, seeing another furnace of molten steel coming out, Chen Sanlian said: "Old classmate, how many furnaces is this?"

Ding Hui said first: "The eleventh furnace, I hope it can be successful this time." ”

This kind of high-strength steel, if smelted successfully, is of great significance, not only can reach the world's advanced level, but also can be widely used in aviation, military weapons and equipment and other fields, especially in the aviation field, can change the situation that this kind of steel has long been dependent on imports.

The molten steel is baked, poured into ingots, cooled, and a series of processes come down, and everyone feels as if it is as long as a century.

Finally began to sample the inspection, Ding Huixian personally looked seriously, under the electron microscope, everything could be seen clearly, after looking at it for a long time, Ding Huixian sighed slightly.

Still failed.

An assistant next to him said, "Ding Gong, do you want to do another strength test?"

Ding Hui said first: "There is no need, I have seen it clearly through the microscope just now, and there are still many tiny cracks between the grains, this furnace must have failed again, and the strength cannot meet our requirements." ”

Chen Sanlian has been personally accompanying Ding Huixian, hearing this, Chen Sanlian also sighed, for this project, Chen Sanlian knew that not only Ding Huixian, but also his own steel group, everyone has paid a lot of effort and energy.

It has been several months, and more than a dozen furnaces of molten steel have been smelted through repeated trials, and this time it was full of hope, but I didn't expect that the greater the hope, the greater the disappointment.

Failed!

Almost all of them had sad faces and sighed slightly, and it could be seen that everyone was hit hard this time, even Chen Sanlian.

However, Chen Sanlian was puzzled, why did he fail again, so Chen Sanlian asked: "Old classmate, according to reason, it will not fail, our steelmaking equipment is imported, fully meets the requirements, a complete set of smelting process is also formulated by you, all the parameters of smelting are well controlled, there is no reason to fail again." ”

Ding Huixian sighed slightly and said: "Alas, Lao Chen, you don't understand, because you are not a professional, perfect and reasonable smelting process, a series of scientific parameters, this must be a major aspect, but for our subject, to smelt successfully, smelting this kind of high-strength steel, the most important and critical thing is not these." ”

Chen Sanlian said: "Old classmate, is it smelting equipment?" ”

Ding Huixian said: "Smelting equipment is also important, but your set of imported smelting equipment has fully met the requirements, in the smelting process, smelting parameters, smelting equipment is not a problem, we still fail, then there is only one possibility, that is, smelting iron ore." ”

It's iron ore!

Unexpectedly, the key to success or failure is iron ore!

"Yes, it's iron ore!" Ding Huixian said: "After so many tests and summaries, I already know that in order to succeed, there must be high-quality iron ore." ”

"It's high quality, not high grade!" Ding Huixian added.

The grade of iron ore mainly represents the content of iron ore in iron ore, and the common iron ore grade is in the 40s, 50s, 60s, and even 65.

The quality is different, not only the iron content of iron ore, but also other factors, such as the content of harmful elements in iron ore, the content of beneficial elements and so on.

The most common harmful elements in iron ore are sulfur and phosphorus. Sulfur reacts with iron to become iron sulfide, which can easily cause hot cracks in the metal during high-temperature treatment. The solubility of phosphorus in solid steel is small, but its presence can severely reduce the impact toughness and low-temperature toughness of the metal. Beneficial elements: carbon, silicon, manganese, W, Cr, Ni, Mo, V, Ti, etc.

After listening to Ding Huixian's speech, Chen Sanlian seemed to understand, and immediately said: "Old classmate, it just so happens that we will go to a batch of Australian mines in the afternoon, and we will try it tomorrow with Australian mines." ”

"Is there an Australian mine? That's great, as soon as the ore arrives, we will immediately conduct sampling and testing, meet the requirements, and we will conduct the test tomorrow morning, if it can be successful, Lao Chen, you Sanlian Iron and Steel has made a great contribution." ”

This is a national project!

Significant!

Sure enough, in the afternoon, an Australian mine arrived at Sanlian Iron and Steel Group Company, and Ding Huixian personally took several of his assistants to personally beneficiate the ore and personally draw for testing......

…………

A few days ago, Liang Hongbo ran these procedures, he was tired to death, and the progress was slow, but now it is completely different.

Now, under the leadership of Liu Yu, the director of the bureau personally warmly received him, and everything went very smoothly, and when he left, the director personally sent it to the gate.

Now it is even more exaggerated, in the Land and Resources Bureau to handle the change of mining license, the director of the bureau is not there, a deputy director reception, the deputy director of the courtesy, so that Liang Hongbo still thinks he is dreaming, secretly pinched his thigh several times.

Niu, Brother Dong is too good, he actually has a friend like Liu Yu.

The mining license was handled, and the mining method was changed from cave mining to open-pit mining, and the deputy director of the people personally cared about the mining area and the scope of the mining area.

Liang Hongbo said: "Zeng Bureau, can you register the mining area and the scope of the mining area a little larger?"

Director Zeng glanced at Liu Yu, who was leisurely drinking tea next to him, and said briskly: "Of course, there is no problem, how much mining area does Mr. Liang want to register." ”

As a result, the scope of registration on the mining license is relatively large, including the entire area of Doujia Mountain, that is to say, the area around Doujia Mountain, with a radius of several square kilometers, is all the mining scope of Xudong Mining Company.

On this mining scope, in the copy of the mining license, it is more detailed explanation and planning, seeing that it went so smoothly, Liang Hongbo quietly pinched himself again, and after feeling the pain, Liang Hongbo realized that he really did not dream.

All the best.

After a few days of hard work, everything is done, as long as the formal procedures come down, this is also greatly unexpected by Wang Xudong, no, Liu Yu has helped so much, Wang Xudong always has to make a phone call to thank you.

"Liu Yu, you gave me a big surprise this time, let's say, how can I thank you?"

Liu Yu laughed on the other end of the phone, "Brother Dong, it's a trivial matter, it's not worth mentioning." ”

Wang Xudong knew Liu Yu's character, Wang Xudong laughed, "By the way, I have already called you for the car, have you received it?"

Last time, Wang Xudong bought a car, but he only paid one million, and he still owes Liu Yu more than one million, and now that he has money in his hand, he is naturally embarrassed to owe this money again.

Liu Yu said: "The money has arrived, Brother Dong, you are worthy of being a local tyrant, you have money in such a short time, and you still got nearly 20 million, cow!"

Wang Xu smiled proudly, and thought in his heart, brother and I are big mine owners, and money is a matter of minutes, or simply not a thing.

No, not long after talking to Liu Yucai on the phone, Song Qingsong came in and said happily: "Boss, our first batch of mining equipment has arrived." ”

The mining equipment has arrived, and the shotgun needs to be replaced with a cannon!
