Method for fitting a break ring to mold in horizontal type continuous casting and apparatus therefor.

摘要

A method for fitting a break ring (6) between a mold (5) and a feed nozzle (4), the molding being horizontally fitted to the lower part of the side wall of a tundish (1) of a horizontally type continuous casting apparatus through a front nozzle (3) and the feed nozzle, which comprises the steps of: allowing a movement of a break ring in horizontal direction by a thermal expansion in a beginning stage of horizontal continuous casting; and imparting a compressive stress to the outer peripheral portion of said break ring for reducing a tensile stress during casting. The compressed force is added by a pull cylinders connected to the mold through piston rod.
