The essence of radiation heat transfer is deeply studied, and the concept of specific heat flow parameter is put forward, which transforms the heat flow equation of radiation heat transfer into random heat flow equation. On this basis, the stochastic theory of radiation emission is combined with the certainty of transmission, and the radiation heat transfer and transport equation (also known as "L-H equation of engineering thermal radiation") is established. Then, for the top-blown converter, the droplet movement, combustion and flow process are organically combined, and the mathematical simulation of the secondary combustion process of steelmaking converter is solved for the first time in the world. The research results have been confirmed by industrial practice and highly praised by scholars in the United States, Canada and other countries.
This achievement won the second prize of the Ministry of Metallurgy for Scientific and Technological Progress (1993). The "combustion process optimization technology and computer control system" developed by this achievement has been adopted by Baotou Steel Strip Plant, creating an economic benefit of 22 million yuan. In 2002, it was listed as the national key promotion project of scientific and technological achievements, and in 2003, 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 crystallizer, electromagnetic stirring and continuous casting secondary cooling, are studied. The three-dimensional mathematical model and calculation software of the whole process of vacuum refining are developed, and the refining processes of RH and LF are optimized. The idea of "crystallizer+sector" dual-zone electromagnetic stirring for continuous casting is put forward, and the sector electromagnetic stirrer is designed. The research results have been applied in Baotou 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 60 million yuan. In 2006, he won the first prize of Inner Mongolia Science and Technology Progress Award and the second prize of National Science and Technology Progress Award in 2007.
(3) Research and application of comprehensive utilization of rare earth and niobium resources.
He presided over the research of new rare earth functional materials, and successively developed gadolinium and its alloys, manganese germanium antimony series alloys, rare earth manganese perovskite and other 12 series magnetic refrigeration materials. The maximum room temperature magnetocaloric effect of 3.2K was obtained in gadolinium and its alloy system, and the first domestic magnetic refrigeration equipment was developed in cooperation with Baotou Rare Earth Research Institute. A series of hydrogen storage alloy materials were prepared by casting-rapid quenching and mechanical alloying. The preparation process and the influence of various substitution elements were studied in detail. In rare earth-magnesium-nickel and magnesium-zirconium-nickel intermetallic compounds, good hydrogen storage performance was found.
At present, the research on the comprehensive utilization of niobium resources in Baiyunebo Mine is under way, and the new technology of niobium resources selection and smelting and the preparation of glass-ceramics from rare earth tailings have achieved initial results, and four national invention patents have been declared.
