Brief introduction of Li Baowei's work

Li Baowei's main research fields are: new processes and technologies for iron and steel metallurgy, and utilization of rare earth and niobium resources in Baiyunebo Mine. He has presided over more than 3 projects, including the 973 Project of the Ministry of Science and Technology, the National Natural Science Foundation of China and the major funded projects of Inner Mongolia Government, won 12 provincial and ministerial level achievement awards, published 3 monographs, applied for 8 national invention patents, published more than 1 academic papers, and more than 4 were included by SCI and EI. (1) Basic research on radiation heat transfer and combustion process < P > The essence of radiation heat transfer is deeply studied, and the concept of specific heat flow parameter is put forward for radiation heat transfer, and the heat flow equation of radiation heat transfer is transformed into random heat flow equation; On this basis, the stochastic theory of radiation emission is combined with the determinism of transmission, and the radiation heat transfer and transport equation (also called "L-H equation of engineering thermal radiation") is established. Then, aiming at the top-blown converter, the mathematical simulation of the secondary combustion process in the steelmaking converter was solved for the first time in the world by organically combining the droplet movement, combustion and flow processes. The results were confirmed by industrial practice and highly praised by scholars in the United States, Canada and other countries.

this achievement won the second prize of scientific and technological progress of Ministry of Metallurgy (1993). The "combustion process optimization technology and computer control system" developed by this achievement was adopted by Baotou Steel Strip Plant, which created an economic benefit of 22 million yuan. In 22, it was listed as a national key promotion project of scientific and technological achievements, and in 23, it won the first prize of scientific and technological progress in Inner Mongolia Autonomous Region.

(2) Research and application of new high-efficiency continuous casting technology

The key technologies of high-efficiency continuous casting, such as secondary refining, continuous casting mold, electromagnetic stirring and continuous casting secondary cooling, were studied, the three-dimensional mathematical model and calculation software of the whole vacuum refining process were developed, the RH and LF refining processes were optimized, the idea of "mold+sector" dual-zone electromagnetic stirring for continuous casting was put forward, and the sector electromagnetic stirrer was designed. The research results have been applied in Baotou Iron and Steel Group, Taiyuan Iron and Steel Company, Baoshan Iron and Steel Group Company, Laiwu Iron and Steel Company and other large iron and steel enterprises, and achieved good technical application results, creating economic benefits of more than 6 million yuan. In 26, it won the first prize of Inner Mongolia Scientific and Technological Progress and the second prize of National Scientific and Technological Progress in 27.

(3) Research and application of comprehensive utilization of rare earth and niobium resources

The research on new rare earth functional materials has been conducted, and 12 series of magnetic refrigeration materials such as gadolinium and its alloys, manganese germanium antimony series alloys and rare earth manganese perovskite have been developed successively, and the maximum room temperature magnetocaloric effect of 3.2K has been obtained in gadolinium and its alloy systems, and the first magnetic refrigeration equipment has been developed in China in cooperation with Baotou Rare Earth Research Institute. A series of hydrogen storage alloy materials were prepared by casting-rapid quenching, mechanical alloying and other methods. The preparation process and the influence of various substitution elements were investigated in detail. Among the intermetallic compounds of Re-Mg-Ni and Mg-Zr-Ni, good hydrogen storage performance was found.
