STOPPER FOR CONTINUOUS CASTING

摘要

A stopper for continuous casting is provided to improve reliability about attachment prevention of aluminous inclusions or its similar foreign matters. A stopper(100) for continuous casting comprises an inner hole part(101) and a plurality of exhaust flow paths(110). Inert gas is flowed into the inner hole part. The exhaust flow paths are radially formed around the inner hole part so that the inert gas is discharged to the outside through a nose part(102) of the stopper. A diameter of the exhaust flow paths is in the range of 0.6 to 4.9mm, and the center of the exhaust flow paths is spaced by 40 to 120mm from a lower end of the nose part.
