CONTINUOUS CASTING MOLD.

摘要

A problem encountered in a continuous casting operation is that a cast piece seizes to the inside of a casting mold when the cast piece is withdrawn from the mold. It is known therefor to mount a plurality of ultrasonic vibrators at prescribed intervals along at least one straight line in the axial direction to the mold on the outer surfaces of the respective side walls thereof. The vibratory action of the ultrasonic vibrators causes the mold to vibrate in the axial direction so as to prevent the seizure of the cast piece onto the inner surface of the mold. The vibrational efficiency induced by the ultrasonic vibrators is unsatisfactory with the aforementioned conventional mold so that it has not been possible to reliably prevent the seizure of the cast piece onto the inside surface of the mold. The continuous casting mold of the invention eliminates the aforementioned problem and vibrates efficiently, and includes a plurality of ultrasonic vibrators mounted at prescribed intervals along at least one straight line in the axial direction of the mold on the outer surface of the respective side walls of the mold, the respective side walls of the mold being secured to a cast frame and including therein at least one cooling water passage along the axial direction, the water passage including a cooling water supply opening and a cooling water discharge opening on the outer surfaces of the respective side walls of the mold. The respective side walls of the mold are secured to the mold frame at the positions corresponding to at least two or more nodes of the oscillatory waves produced in the axial direction of the mold by the vibration of the ultrasonic vibrators. The cooling water supply opening and the cooling water exhaust opening are disposed respectively at the positions corresponding to the respective nodes.
