摘要： There is disclosed a method by which a channel-type induction heating apparatus is provided on a tundish, which comprises a steel receiving chamber and a steel discharging chamber separated by a refractory wall, each of which chambers is connected to the ground via molten steel flowing from a ladle, molten steel flowing into a mold, or a refractory, in such a manner that ground circulating current is prevented from being generated. An electromagnetic connection of an induction heating coil and an iron core of a two-leg type or a three-leg type to a loop current circuit in the molten steel is arranged symmetrically, thereby suppressing the generation of the ground circulating current. By thus suppressing the generation of the ground circulating current, it becomes unnecessary to insulate a ground circuit as required in conventional constructions, the maintenance of facilities becomes easier, besides any malfunction of the equipment due to the ground circulating current is totally eliminated.
