FIELD: metallurgy, in particular, constructive members of vacuum arc furnaces and electron beam furnaces using water-cooled melting tool. SUBSTANCE: melting tool has metal casing with working surface and hermetically sealed inner cooling channels with inlet and outlet openings for connecting cooling system pipelines. Cooling channels are arranged at different levels, are connected in series and defined by separating partitions in continuous slot formed in tool body. EFFECT: increased efficiency owing to complicated three-dimensional shape of working surface, optimal arrangement of water-cooled channels, increased strength and simplified manufacture by means of standard equipment. 5 dwg, 1 ex
