Tundish for continuous casting and grade transition metod using same

摘要

The present invention relates to a tundish for continuous casting and a tundish type converting method using the tundish. The tundish of the present invention includes a tundish, which is provided with a tundish main body, which is provided with molten steel through an injection nozzle and supplies the molten steel, ; A lifting dam provided on the tundish main body so as to be able to move up and down; And a weight system installed in the tundish main body and sensing a decrease in the molten steel in the tundish main body so as to control the lifting and lowering of the lifting dam, It is possible to remarkably reduce the rate of occurrence, thereby increasing the error rate.
