Abstract：As a clean, efficient and non-contact control method, electromagnetic field plays an important role in the field of iron and steel metallurgy. In this paper, the research progress of electromagnetic field in steel material preparation in recent years is reviewed. The application status of new electromagnetic metallurgy technology in the process of continuous casting, solidification and solid phase transformation of iron and steel is mainly introduced, including the induction heating of tunds, electromagnetic current control of slab continuous casting, pulsed magnetic oscillation, magnetically controlled electroslag remelting and the regulation of magnetic field on martensitic transformation and carbide precipitation behavior. At the same time, the action mechanism of magnetic field in different metallurgical processes is described, and the future research and development direction is prospected.
