Thin-walled mold for the continuous casting of molten metal

摘要

A mold for continuously casting of billets comprises an inner copper mold and an outer steel envelope surrounding the mold. The outer envelope is affixed to the inner mold by threaded tie rods which are anchored to parallel longitudinally extending ribs on the exterior faces of the inner mold. These ribs define grooves therebetween and the interior faces of the envelope have parallel longitudinally extending ribs facing the grooves. The facing ribs and grooves define therebetween longitudinal channels for a cooling liquid for the mold.
