Chapter seven hundred and forty fourth high temperature superconducting coil
Sticks and carrots are always the best combination. In the desperate situation, most of the small steel mills in Xingchuan County accepted the plan proposed by Qin Hai. They freely combined according to their distance and proximity, with an average of more than a dozen companies.
Hehejia, using the original equipment and backlog of raw materials as collateral, applied for a loan from Qinhai to update equipment, purchased second-hand equipment, and established a number of new steel plants with a certain technical level that reached the production scale specified by the National Economic and Trade Commission.
.
During the period when the steel products were seized by the working group, many small bosses borrowed loan sharks due to lack of funds, which became a worry for them. Qin Hai borrowed the help of Guo Qiushi to launch a crackdown in Xingchuan County
The special operation on loan sharking eliminated several gangs that specialized in making profits from loan sharking, helping small bosses get rid of the nightmare of loan sharking. This move won him a lot of praise among small bosses.
Li Linguang brought a group of students to provide technical guidance for the new steel plants in Xingchuan, helping these steel plants quickly get on the right track. The energy consumption and raw material usage efficiency of the new steel plants are much higher than those of the previous small workshops. Due to the quality of the products
It is reliable, and the price of finished steel products is much higher than that of previous strip steel, so the profit margin is much higher than the original level. The current domestic steel market is still in a state of short supply, and the products of these new steel mills have no worries about sales.
The benefits can be described as making money every day. In this way, the last grudges in the hearts of the small bosses disappeared, and everyone regarded Qin Hai as their savior.
Of course, there are also people like Lu Quanlin who have recognized a dead reason and are determined not to cooperate with Qin Hai. For these people, Qin Hai is too lazy to care about them and lets them fend for themselves. Lu Quanlin originally
They also planned to take advantage of the new steel plants in the county to start production one after another to continue to produce some strips of steel and transport them out to sell them for money. Unexpectedly, the newly established steel plants in Xingchuan County jointly established an industry association to specifically deal with
The steel shipped out of Xingchuan County is inspected. If it does not meet the standards, it is not allowed to leave the country. Although Qin Hai's working group has withdrawn, Lu Quanlin and some other remaining strip steel companies are still unable to operate. In the end, it is inevitable that they will go bankrupt.
path of.
The successful experience of Xingchuan County's small iron and steel transformation was quickly promoted, and a vigorous campaign to seize ground steel was launched across the country.
No matter how well the strip steel manufacturers hide their products, their products will eventually be transported on the road. The Economic and Trade Commission, together with the public security and armed police and other departments, have established a number of checkpoints in areas where strip steel is rampant to specifically inspect the steel products transported in the past.
, cutting off the channel for the outbound transportation of strip steel. This move was both simple and effective, and soon put strip steel production companies everywhere in dire straits.
Subsequently, the Steel Enterprise Upgrading and Transformation Foundation led by Daqin Group began to intervene, relying on the strong financial resources of Daqin Group. The foundation facilitated the merger of thousands of strip steel companies and carried out technological upgrades, putting them on a sound path.
path of development.
At the same time, the steel industry alliance with Daqin Group as the core has gradually taken shape. At the beginning, only small steel companies that had received funding from Daqin Group joined the alliance. As the "Steel Alliance" became more and more popular, some with certain
Large-scale private steel companies have also chosen to join the alliance in order to obtain the protection of the alliance. Metallurgical expert Li Linguang was hired as the honorary chairman of the alliance, while Song Hongxuan served as the chairman of the alliance and was responsible for specific work.
Naturally, it was impossible for Qin Hai to participate in all these tedious matters. He explored a model to solve the problem. This contribution was very huge. After reading the internal reference on the management of small iron and steel in Xingchuan County, the chief happily wrote
He wrote a long paragraph of instructions and spoke highly of the work of Qin Hai and the Economic and Trade Committee. There is no need to go into detail about these things.
During the period when Qin Hai was concentrating on the integration of the steel industry, Daqin Group's other work did not stop. The most exciting thing among them was the major breakthrough in the research on iron-based superconducting materials presided over by Ning Jing.
Her team used iron-selenium compounds doped with rare earth elements to obtain superconducting properties in a "high temperature" environment of 240k, setting a new record for high-temperature superconductivity.
The temperature of 240k, converted into the commonly used Celsius temperature, is equivalent to minus 30 degrees. For the human living environment, it is an extremely low temperature. But for superconducting materials, superconductivity can be obtained at a temperature of 240k.
This is already a remarkable achievement. The highest critical temperature of traditional superconducting materials is only over 100 K. Liquid nitrogen needs to be used as a medium to maintain low temperatures. When the critical temperature increases to 240 K, the low-temperature medium only needs to use liquid carbon dioxide, ammonia, etc.
However, ordinary household refrigerators can produce such low temperatures, which greatly reduces the application cost of superconductors and dramatically expands the application fields of superconductors.
The development of high-temperature superconducting materials with a critical temperature of 240K was certainly not achieved overnight. Ning Ning led a team of hundreds of people and tested tens of thousands of materials over four or five years before achieving such results. According to Ning Ning
According to the statement, every 1 degree increase in the critical temperature of the superconducting material they studied would cost tens of millions of yuan. No laboratory in the world could have such strong financial support, so this material was eventually acquired by Kyungseong University.
, which is not surprising.
The advent of iron-selenium superconducting materials has set off a new round of superconducting research craze around the world. Governments and enterprises around the world have realized the new opportunities that high-temperature superconducting brings to fields such as science and technology, national defense industry, etc., thus changing the past understanding of
Superconducting research has a dubious attitude, and they are investing manpower and material resources in an attempt to occupy the peak of superconducting applications.
As the inventor of iron-selenium high-temperature superconducting materials, Ning Jing has naturally become a hot commodity. Countless academic conferences have sent her invitations, and many companies have offered her high remuneration to hire her as technical guidance.
She was busy dealing with various demands all day long, and she took planes almost more often than others took taxis, so that if Qin Hai wanted to see her, he had to rush to this secret naval base on the coast of the East China Sea.
"Haha, it turns out that President Qin is here. It really makes our place shine."
Navy Chief Engineer Zhou Linlei came to the base gate in person to greet Qin Hai, and he laughed and joked upon meeting him.
"There is nothing I can do. My wife is being held here by you. Can't I come over and visit her?" Qin Hai said with a smile while shaking hands with Zhou Linlei.
Zhou Linlei said apologetically: "I'm really sorry, we left Xiao Ning here to help us with our research, which caused Mr. Qin to come over to visit even though he was busy. But there's nothing we can do about it. We don't have expertise in superconducting materials.
Talent, we can only rely on Xiao Ning to help us."
"This is what it should be." Qin Hai said. After saying that, he asked in a low voice: "How is it going, Mr. Zhou? Is it going well?"
Zhou Linlei also lowered his voice and said with an excited look on his face: "It went very smoothly. The results of the ground experiment fully met the expected requirements. It won't be long before we can conduct experiments on the ship."
"Great, it seems that the launch of our aircraft carrier can be greatly advanced." Qin Hai said happily.
This naval base specializes in the study of aircraft carrier catapults. Previously, catapults on aircraft carriers were driven by high-temperature steam. The device structure was complex, and the construction and maintenance costs were very high. Countries around the world are actively studying electromagnetic
ejection technology, but they all face a series of technical bottlenecks.
Zhou Linlei studied electromagnetic catapult in his early years. Because the key technology has not been able to achieve breakthroughs, electromagnetic catapult has always been just a concept and has not been formally approved for development. After developing the supercapacitor in the School of Materials, Zhou Linlei realized the opportunity to develop electromagnetic catapult.
has matured, so the upper levels of the Navy were persuaded to start the research work on electromagnetic catapults. The emergence of high-temperature superconducting materials removed the last obstacle in Zhou Linlei's development of the electromagnetic catapult system for carrier-based aircraft, making the advent of aircraft carriers just around the corner.
The principle of electromagnetic ejection is not complicated. It uses the principle of magnets of the same nature to repel each other. Current is passed through a coil to generate strong magnetism and push the traction slider to move at high speed, thereby ejecting the carrier-based aircraft.
.
In the electromagnetic catapult system, the energy storage device and the coil are two key difficulties. The electromagnetic catapult must eject an aircraft weighing dozens of tons in a very short time, and the energy storage device is required to provide a strong current in an instant.
At the same time, the coil is also required to be able to withstand such a large current. The technology to solve the former difficulty is supercapacitor, while to solve the latter difficulty, high-temperature superconducting materials are needed.
Electromagnetic coils made of superconducting materials have no resistance, so they will not generate high temperatures when extremely large currents pass through them. This is an advantage that ordinary wires do not have. A few years ago, Qin Hai predicted high temperatures to Zhou Linlei
With the emergence of superconducting materials, Zhou Linlei also designed electromagnetic coils based on this prediction. After Ning Jing studied iron-selenium high-temperature superconducting materials, Zhou Linlei immediately contacted her and invited her to the naval base to assist in the development of superconducting coils.
development.
These situations, of course, are highly confidential to outsiders, but in front of Qin Hai, there is no issue of confidentiality. Qin Hai helped Zhou Linlei solve the two key issues of electromagnetic ejection, so why would Zhou Linlei have to
Keep secrets from him.
Under the guidance of Zhou Linlei, Qin Hai walked into the heavily guarded experimental workshop. As soon as he entered, he saw a group of people busy around a huge device. One of them was wearing work clothes and was explaining something to a few people.
, it was the tranquility he had not seen for many days. To be continued
