According to 'China Magnesium Industry', the R&D team of Beihang University and Linjiang Magnesium Industry Co., Ltd., led by Professor Zhang Tao, the chief scientist of the National 973 Project, jointly released the first ultra-fine magnesium alloy with a fineness index of 1000-3000 mesh in China. Powder and manufacturing system development results. After evaluation by experts, the successful research and development of the technical equipment and preparation process has filled the technological gap in the domestic industry and has reached the advanced technology level of the same industry in the world.
At the meeting, many experts in the related fields of China's non-ferrous metal industry said that magnesium is the third largest metal engineering material after iron and aluminum, and magnesium is known as the green metal with the most development and application potential in the 21st century. China's magnesium resources are widely distributed in all types, and the total reserves account for 22.5% of the world's, ranking first in the world. The fine processing and efficient utilization of magnesium resources will effectively alleviate the tension of metal resources such as iron and aluminum.
Chang Wenguang, chairman of the board of directors of CICC Foundation Group and chairman of Linjiang Magnesium Group, introduced that the magnesium powder in the domestic market is mainly concentrated within 150 meshes, the process is complex and the cost is high, and most of them are provided for industrial production needs, only a small amount Provided for the completion of aerospace use. The production fineness is 1000 mesh to 3000 mesh magnesium alloy powder. The main physical and chemical indicators are international and meet the international general military standards, which will produce huge economic and national defense benefits in the fields of national defense industry, energy vehicles, aerospace and other fields.
After evaluation by experts, it is believed that this achievement has reached the international leading level, which is of great significance for realizing the safe production of ultra-fine magnesium alloy powder, improving the quality of magnesium products, and broadening the application field. The results of this technology fill the gap in the domestic technology field of the same industry, and are the world's leading technology in the same industry, which will play an important role in promoting technological innovation in aerospace, national defense and military industries.
Professor Zhang Tao from Beihang University gave a detailed report on the project of 'Development of Ultrafine Magnesium Alloy Powder and Manufacturing System'. He believes that the application of the newly developed advanced atomized magnesium powder technology and international leading equipment to realize the mass production and fine development of ultra-fine magnesium powder is conducive to the industrialization of laboratory results and the continuous improvement of this technology in practical applications. It will fill the gap in the field of ultra-fine production of rare metals in my country.
