Independent Innovation makes rare Earths more and more "easy to use"

SMM News: a few days ago, the rare earth ferroalloy of North China rare Earth (Group) High-tech Co., Ltd. made a new breakthrough in the application of brand steel, cast steel and special steel. Baotou rare Earth Institute uses rare earth ferroalloy as raw material for rare earth steel production, and has successively realized nine continuous pouring and 14 continuous pouring in the industrial production of rare earth steel, which verifies the unique advantages of rare earth ferroalloy in steel application. Experts said that the production of rare earth steel by a new generation of rare earth ferroalloy can solve the problems of flocculation of molten steel and low and unstable yield in the production process in one fell swoop, thus bringing China's iron and steel production technology to a new level.

"rare earths are important basic materials for cutting-edge scientific and technological fields such as new energy, new materials, aerospace, information, biology, military industry, and so on. It can be said that the role of rare earths is everywhere." Chi Jianyi, director of the Baotou rare Earth Research and Development Center of the Chinese Academy of Sciences, said that with the continuous development and progress of technology, China's scientific research institutions and high-tech enterprises rely on rich rare earth resources and new technology. has been able to produce rare earth colorants, rare earth glaze ceramics and other new products for cosmetics.

China is the largest country in rare earth resources, and it has been proved that the amount of rare earth resources is about 65.88 million tons. The world's largest rare earth mine is in Baiyun Obo, Baotou City, Inner Mongolia Autonomous region. The backwardness of rare earth application technology once restricted the development of China's rare earth industry and even modern industry, resulting in the dilemma of "digging soil and selling soil".

Since the new century, China has begun to gradually restrict the export of rare earths, and increase the investment of manpower and material resources in the development and utilization of rare earths. As a result, the preparation and application technology of new rare earth materials in China are advancing by leaps and bounds. The core new materials derived from rare earths in China's aerospace equipment have changed from "mainly relying on imports" to "more and more localization".

The success of "Shenzhou" and "Chang'e" has written the legend of China's space industry again and again, which has attracted the attention of the world. Among them, the samarium cobalt permanent magnet radiation ring developed by the rare Earth Institute of Baotou Iron and Steel Co., Ltd., which successfully provides rocket accurate positioning and navigation services. Samarium cobalt permanent magnet radiation ring is a small part, but it is used in the gyroscope of rocket control platform, which can automatically control the speed of motor and adjust the direction of rocket to ensure that the launch target can enter the predetermined orbit accurately.

The rare earth industry, which is becoming more and more powerful, has broken through the pass again and again, and has played an important role in the power of science and technology.

In 2018, the first magnetic resonance diagnosis and treatment vehicle with independent intellectual property rights was put into use in Xianbao Bo, Baotou City, which has become another classic example of the application of rare earth permanent magnet materials in China. In an interview with reporters, Yin Jianwei, general manager of the company, said: "our products are the terminal products that use the most rare earth permanent magnet materials. Magnetic materials account for 60 percent of the cost of permanent magnet magnetic resonance equipment, and the production plan has been fully realized. The annual consumption of high-grade magnetic materials is more than 1000 tons. "

In 2019, Baotou Jinshan Magnetic material Co., Ltd. passed the acceptance of "High performance low Vortex Sintering ND-Fe-B Magnetic Steel Manufacturing Technology for High Frequency permanent Magnet Motor", which improved the problem of high eddy current heating of magnets in high frequency application field, and made the comprehensive magnetic properties of magnets greater than 74, A great breakthrough in the performance of double high magnets with high magnetic energy product and high coercive force has been achieved. In the current industrial field and manufacturing production line in China, such achievements are numerous.

As one of the witnesses to the rapid development of new rare earth materials in northern China, Chi Jianyi said: "the efficient utilization of rare earths should start from two aspects: extraction, separation and application research and development, both of which are indispensable. It is gratifying that with the extraction and separation technology of rare earth elements in China gradually entering the ranks of advanced levels in the world, the development of new material preparation technology has also made remarkable achievements. "

In recent years, more and more "rare earth new materials made in China" have gone to the world. Just take the permanent magnet industry as an example: with the gradual development of new energy vehicles in the future, the total sales volume of new energy vehicles in the world is expected to reach 20 million in 2020. According to the calculation of 2.5kg of permanent magnet materials per new energy vehicle, the global demand for permanent magnet materials for new energy vehicles will reach 50, 000 tons. With the development and manufacture of new permanent magnet materials in China becoming more and more mature, this value derived from the high-end application of rare earth is astronomical in itself.

The efficient development and utilization of rare earths is effectively promoting the upgrading of China's multi-field industries: rare earth permanent magnets, rare earth luminescence, rare earth hydrogen storage, rare earth polishing and other rare earth functional materials are widely used in electronic information, national defense military industry, energy saving and emission reduction, green environmental protection, bioengineering and other fields, realizing the rapid rise of many emerging strategic industries.
