This paper explores the microstructural evolution of different refractory materials during the converter steelmaking process and their impact on material properties.By simulating the experimental design and microscopic analysis of the convert-er steelmaking environment system,the microstructure changes of magnesia carbon brick and aluminum magnesium spinel brick under high temperature conditions were studied,including the evolution of grain size,phase composition,and pore struc-ture.In the high-temperature environment of converter steelmaking,the grain size of refractory materials significantly grows,and some oxide phases react or react with slag to form new mineral phases,resulting in an increase in porosity and a decrease in the compressive strength and thermal shock stability of the material.Based on these research results,suggestions for optimiz-ing the selection of refractory materials and the process of furnace repair were proposed,and possible ways to improve the per-formance of converter refractory materials in the future were explored.This provides a scientific basis for the application and optimization of refractory materials in converter steelmaking process,and has important industrial application value.
