摘要: A water-cooled sliding mold for the electro slag remelting of a billet with a slag layer covering the billet is made of a relatively large cross section tubular member which includes an upper part having substantially smooth constant cross section, a middle part having a substantially smooth downwardly diminishing cross section and a lower part having an irregular cross section which includes inwardly extending portions at spaced locations around the periphery which extend below the smallest cross section of the middle part. The construction is such that the slag becomes separated from the metal at the beginning of the inwardly extending portion of the lower part of the mold. The lower part advantageously includes a wave-like formation which projects into the mold interior which act to crush the slag shell and the slag fragments fall down off the mold. The cooling of the billet and the removal of the slag particles is also improved by circulating a cooling medium in the lower part of the mold.
