CRYSTALLIZER FOR CONTINUOUS AND SEMI-CONTINUOUS CASTING COPPER AND COPPER ALLOYS

摘要

A crystallizer for continuous and semi-continuous casting copper and copper alloys comprises a metal body, copper water-cooled walls of workspace, a protective coating of copper walls, a water cooling system. The copper plates of wide walls are made ​​with a concave upper surface of the working part on the area of 0.7-0.8 of the crystallizer height from its upper end. The concavities have a segment configuration of circular cone formed by intersection of the cone by a plane parallel to the axis of cone. Chord length of the base segment is equal to the broad wall of the crystallizer, the angle of cone generatrix with the cone axis is 0.65-0.85 %. Height of the base segment of concavity at the level of the upper end mid – 1.5- and is reduced downward the crystallizer.
