Rewrite the Technological Landscape

In addition to the export ban, Qinchuan Electronics should be able to get more financial support at Wei Zhicheng's request.

It can be seen that the country is really starting to care about the research and development of high-end materials.

After lunch, he sent the leader away, but when he was drinking tea in the office in the afternoon, Wei Zhicheng said with a face full of pressure, "Now I understand how awesome Dafeng Group's research and development of lithography machines is. It's too difficult."

"Our military's research and development has always been at the forefront of technology, and the Dafeng Group is not worth mentioning in comparison."

"That's not what I said." Wei Zhicheng shook his head, "To be honest, many of our products were developed in reverse in the early years, but when we started to challenge high-end materials, the advantages we had established before could no longer be achieved. It does a lot of work."

Meng Qian asked curiously, "That's what you say?"

"In the past, when we got a piece of material, we would measure its composition and ratio, and further understand the arrangement rules between different atoms. We can complete these steps in a few days. Even for high-end materials, we can also complete them in a few days. The product structure can be analyzed within a short period of time, but if it is ordinary equipment and ordinary materials, the production can basically be reversed at this point.

But when it comes to high-end materials, even if we know the rules of atomic arrangement, we have no way of knowing how it is realized. To give a popular example, the same dish, exactly the same ingredients, and exactly the same ingredients, but ordinary people What the chef makes is two flavors.

If you want to become a chef from a layman who has never cooked, you can only practice and try again and again. The only way to speed up the progress may be talent, that is, we need a group of material science geniuses, but this kind of Things come and go.

This is still reverse R\u0026D. If it is forward R\u0026D, it will take more time and cost, so the biggest problem for us now is genius-level talents and time cost. "

Meng Qian is also a little helpless. The research and development of high-end materials is so difficult, and no one can change it. "So I have proposed time and time again to change the domestic material research and development environment. We must encourage and support more people to enter this field. OK."

"But there is something more helpless, that is, the prohibition of some rare raw materials, such as the most critical part of the aerospace engine, the rhenium-nickel alloy single crystal blade, which is a topic we are particularly anxious to break through. If there is no such Things, we have to use other people's single crystal blades on our fighter jets, and we may get stuck in the neck at any time.

Wei Zhicheng took a sip of tea and suddenly found that Meng Qian next to him didn't respond. Turning his head curiously, he saw Meng Qian frowning, "What's wrong, Mr. Meng?"

Meng Qian was awakened by Wei Zhicheng, and made a gesture to wait a moment.

"Why does Rhenium feel so familiar." Meng Qian tried his best to dig out the flashing thing just now, "Wait! Chang'an! Rhenium! How can I forget such an important thing!"

If the post-80s are technical geeks, especially military fans, most of them have seen a news in 2010. At that time, there was a lot of excitement in the industry. Rhenium was detected in the mine, breaking the monopoly of the United States. Five years later, in 2015, China's single crystal blades were successfully released.

But the problem is, Meng Qian only remembers such a thing. He only remembers that he was in Shanxi Province. He can’t remember which county or mine. In Shanxi Province, the most indispensable thing is the mining area.

so awkward.

Meng Qian was in no mood to stay any longer, and he couldn't tell anyone about it, so he had to act on his own.

After trying hard for a long time, I still can't remember it, but I have a vague memory. Meng Qian can only go to understand the general situation first, anyway, knowing that there is such a thing, it is impossible to do nothing.

Meng Qian contacted an industry insider through personal contact.

Through the introduction of industry insiders, Meng Qian learned some useful information. Rhenium can not be dug everywhere. Rhenium is mostly associated with molybdenum, copper, lead, zinc, platinum, tantalum, niobium, rare earth and other minerals in trace amounts. The raw materials for extracting rhenium with economic value are molybdenite and copper concentrate, among which molybdenite is the main source of rhenium.

And when Meng Qian saw the three words molybdenite, it also stimulated the memory in his brain, which is rhenium found in a molybdenum mine. Meng Qian continued to inquire and learned that there are now almost 20 molybdenum mines in Shaanxi Province. All of a sudden it shrank.

But when Meng Qian learned about the situation of these more than 20 molybdenum mines, he was confused again. The medium-sized molybdenum mines and large-scale molybdenum mines are very large. It is impossible for Dafeng Group to buy these molybdenum mines and mine them one by one. There is a problem. Meng Qian doesn’t know anything about this industry. After being educated, he realized that there are strict standards for the scale of mining in mining areas. It doesn’t mean that if I have money, I can increase the scale of mining by buying more equipment and recruiting more people.

Geological conditions, transportation conditions, environmental protection, safety, and local industrial structure and many other factors must also be considered. After the mining scale of a mining area is determined, no matter how much money you have, you cannot exceed this scale. Illegal actions are another matter.

Seeing that they were at an impasse again, Meng Qian asked without thinking, "Old Hou, is it possible to find rhenium in these molybdenum mines?"

"It's not."

"Huh?" Meng Qian suddenly became energetic.

"The geological structure in different places is different, and the molybdenum deposits formed are also different. For example, the molybdenum deposits in Jinduicheng belong to the open-pit mining area, and the molybdenum deposits in Ankang belong to the contact replacement type in the contact zone between granite and surrounding rocks. Molybdenum mines, generally speaking, there are only five molybdenum mines on the edge of Shangzhou, which are large-scale deposits, where copper, rhenium, lead, silver and other elements will be associated."

"Can I see the specific information of these five molybdenum mines?" Narrowing down from 20 to 5, the scope became smaller again, and Meng Qian once again ignited hope.

After getting the information of these five molybdenum mines, Meng Qian first checked their precise addresses, and then checked the names of the molybdenum mining companies.

Until he saw a molybdenum mine located near Huanglongpu Village, Shimen Town, Luonan County, and then Meng Qian saw that the mining company of this molybdenum mine was Shaanxi Lianshi Mining Co., Ltd., and the things in his memory immediately overlapped. That's it!

The most important thing is that the word Huanglong impressed Meng Qian very much. When I read the news back then, I thought it was really interesting to find rhenium on such a place name, as if it was destined by heaven, and Chinese people are very fond of dragons. Sensitive, Meng Qian always remembered that there was a dragon before, and looking at the places where the other four molybdenum mines are located, it has nothing to do with dragons.

Another point is that among the five molybdenum mines, only this molybdenum mine is a large molybdenum mine, and the other four are small molybdenum mines. Meng Qian has a little impression that the news mentioned that it is a large molybdenum mine.

After confirming the address, Meng Qian hurried to check the details.

As a result, as soon as I arrived at the destination, I was stunned again. The area of ​​this mining area is 0.724 square kilometers, and there are more than 10 ore bodies in the deposit. Among them, the largest No. Ⅷ ore body is 640m long and 120m thick.

This mining area has been put into trial production since September 2005, and it took five years for rhenium to be explored until 2010. But as I said before, the scale of mining is limited, so even if Meng Qian bought it , and it is still based on this scale of mining, maybe it will have to wait for five years.

It is not easy to find this place, and it is impossible for Meng Qian to know the exact location where rhenium was found.

"This day's mood is really up and down." Meng Qian couldn't help laughing at himself.

But self-deprecating is self-deprecating. When Meng Qian stood in the mining area and knew that there was rhenium here, he was unwilling to do nothing at all. Just like the export of KFBB crystals was banned a few years ago, we could mine our own rhenium a few years earlier, at least for some The research and development of materials in the field is helpful, such as aircraft carriers, fighter jets, and large aircraft

In the end, Meng Qian made up his mind, "Let's try subdivision mining first. If it doesn't work, then we can only tell a kind lie."
