Abstract
A crucible is disclosed for use in an induction furnace comprising a bottom wall and a circumferential sidewall. The sidewall comprises a plurality of vertically extending wall elements arranged parallel to each other. Each wall element has circumferentially spaced apart transverse faces and a duct means traversing therethrough in open communication between the spaced apart transverse surfaces. The duct means of each wall element are in aligned facing relation with the duct means of adjacent wall elements. An electrically insulating joint is interposed in sealing relation between each of the adjacent wall elements and having duct openings therethrough in open registry with the ducts presented by adjacent wall elements to form at least one channel interconnected between the crucible wall elements to carry a cooling liquid.
