Mainly engaged in systematic research on steel metallurgy, metal materials, metallography and heat treatment, and the dispersion and strengthening laws of metal oxide particles by rare earth injection in molten steel. In the development process of new materials, he has made outstanding contributions to solving some major process and quality problems. Such as solving problems such as steel smelting, forging, heat treatment and fracture flash point. Systematic research has also been conducted on the damage and fracture failure of metal materials during use. As one of the project leaders, his research on 717 steel won the third-class National Invention Award in 1985. The development, promotion and application of 717 steel won the Shenyang Revitalization Award in 1985 and won the first-class Scientific and Technological Progress Award of the Chinese Academy of Sciences. Research on 716 steel won the second prize for Scientific and Technological Progress Award from the National Defense Industry Office of the State Council in 1980. Research on special materials for power station boiler feed water pumps won the third prize of the Scientific and Technological Progress Award of the Chinese Academy of Sciences in 1986. The development, promotion and application of special materials for power station boiler water pumps won the second prize of the Liaoning Provincial Government's Science and Technology Progress Award in 1996. The development of WTNC50-70 non-magnetic petroleum drill chain won the third prize of the Chinese Academy of Sciences' Science and Technology Progress Award in 1997, and the third prize of the Liaoning Provincial Government's Science and Technology Progress Award. award. High-strength non-magnetic drill collar steel was granted a national invention patent in 1998 (Patent No. ZL93115802.8). Representative papers include "The Effect of Spraying European Rare Earth Oxide Particles on Liquid Steel on the Strength and Toughness of Low Carbon Steel", "Research on High-Strength Non-Magnetic Drill Town Steel N131O", "Failure Analysis of Petroleum Drill Collar" and other more than 20 scientific research papers. articles, published in different journals. In recent years, the main research work includes the research of low carbon stainless steel, non-magnetic steel, heat-resistant steel, high-strength steel, petroleum steel and new dispersion-strengthened materials.
