PROBLEM TO BE SOLVED: To provide a continuously casting tundish, which can actively separate and remove enclosures by sufficiently uniformly mixing hot molten metal in the tundish, and has a molten metal heating device which requires no large scale facilities, and further to provide a method of continuous casting using the same tundish. SOLUTION: The continuously casting tundish receives the molten metal poured from a ladle 1, and pours the received molten metal into a casting mold for continuous casting. The tundish has a molten metal reservoir 7 at a molten metal receiving portion 9 to which the molten metal is poured from the ladle 1. An induction heating coil 6 is arranged on the outer circumference of the molten metal reservoir 7 so as to surround the molten metal reservoir 7. AC current can be supplied to the induction heating coil 6. The height H from the bottom portion 11 of the molten metal reservoir 7 to its top portion 10 is equal to or larger than the diameter D of the equivalent circle of the molten metal reservoir 7. The method of continuous casting uses the tundish described above. COPYRIGHT: (C)2008,JPO&INPIT
