Mold for continuous casting of rounds or billets

摘要

A tubular mold is included in a coolant container there being a tubular guide sheet arranged around the mold at a certain distance therefrom, the coolant flows through the gap between the mold and the guide sheet; as specific improvement the upper portion of the mold has grooves cut into the outside to be flown though by water offering therefore a relatively enlarged cooling surface as compared with the remainder of the configuration of the mold underneath, the guide sheet has a radially inward extension such that water is forced into and through the grooves; these grooves are provided in the area in which the liquid bath level is expected to occur in the mold.
