Abstract

Abstract

This is a paper in the field of ceramic materials for metallurgy. Magnesia chrome refractory is widely used in copper industry due to its excellent high temperature strength, fine slag corrosion resistance and good performance. In this paper, the research status of corrosion mechanism of magnesia chrome refractories for copper metallurgy is summarized theoretically, and the effect and action mechanism of factors on the service life of metallurgical furnace was clarified, such as slag temperature, grade, Cr₂O₃ content and additives in magnesia chrome bricks. Finally, according to the research status, the main ways to improve the service life of magnesia chrome refractories are summarized, which will provide guidance and help for the structural design and performance control of magnesia chrome refractories in the future.
