APPARATUS FOR CONTINUOUSLY CASTING THIN METAL PLATES.

摘要

Double roll type appts. is for continuously casting thin metal plates through a clearance between a pair of internally cooled rolls rotating in the opposite directions. Side dams provided on both sides of the roll pair consisting of an upper dam of a refractory material and in a lower movable dam in a position close to the narrowest portion of a clearance between the roll pair and adapted to be moved in the same direction as and synchronously with a metal plate being cast. The upper dam is formed out of a refractory capable of being cut excellently. Mechanisms for feeding the upper dams in the casting direction are provided. A casting operation is carried out as the bottom surfaces of the upper dams are ground against and worn on the circumferential surfaces of the rolls by these mechanisms.
