Abstract: The channel type tundish induction heating and refining technology for continuous casting was summarized in this paper, meanwhile its general development situation in foreign countries was introduced. The differences between this technology and plasma heating were compared briefly，a simple and clear survey about working mechanism of heating and inclusion removing was given, a domestic independently developed, possessing autonomous intellectual property, “V” shaped channel type tundish induction heating and refining technology as well as its characteristics were presented especially, the reliability, operability, controllability and security of this technology and its good metallurgical effect due to fine heating and inclusion removing were tested and verified by examples applicated in two steel plants, the possible influence to continuous casting technology by this technique was briefly looked ahead.

Key words: tundish, induction heating, constant temperature casting
