Abstract Channel-type induction heating device is added to the ordinary tundish, and the tundish electromagnetic induction heating equipment is industrialized under the condition of not changing the position of the existing continuous casting machine's ladle spout and the tundish pouring port. The eddy current partition on the tundish shell, the heating efficiency of the induction heater and the refractory materials of the induction heating tundish are mainly studied.The research results show that the use of eddy current isolation technology can effectively suppress the eddy current heating of the tundish shell and better solve the problem of eddy current heating of the tundish shell.In addition, by optimizing the structural design of the inductor and adopting key technologies such as aerosol mixing and cooling, the industrialized operation of the tundish induction heating technology has been realized, and the precise temperature control of the molten steel temperature of ±3 ℃ in the tundish has also been realized.

Key words： tundish induction heating equipment industrial application develop
