STATE OF THE ART IN TUNDISH WITH INDUCTION HEATING (IH) FOR CLEAN STEEL CASTING

摘要

The electrical magnetic field plays an essential role in controlling the molten steel flow, heat transfer and migration of inclusions. Electromagnetic induction heating technology utilizes the force or heat effect of the electromagnetic field or simultaneously uses force and heat effect to control molten metal flow, heat transfer and the movement of non-metallic inclusion in the metallurgical process, to optimize the metallurgical process, improve production efficiency, quality, and performance. In this work, the development of IH in continuous casting tundish was outlined. The current theoretical and experimental research on electromagnetic induction heating for molten steel flow and heat transfer were introduced. Meanwhile, the electromagnetic purification mechanism and research progress of non-metallic inclusions in molten steel were analyzed. Finally, the prospects for the application of electromagnetic IH are proposed.
