ABSTRACT:
A metallurgical induction heating apparatus has an upwardly cupped induction coil having a housing formed with an upper rim and containing a heavy-duty coil. A crucible formed of a metallic base pan and a metallic holding collar interconnected by a plurality of upright tubular tierods so as to clamp a multiplicity of refractory bricks has an annular upper support body which extends outwardly beyond an upper mounting ring to which the upper ends of the tierods are connected and which rests on the rim of the induction heater. Means is provided for circulating a coolant fluid upwardly through the tierods and into an annular compartment formed inside the support body. A hood may be placed over this arrangement in gas-tight contact with the upper surface of the annular body so that the interior of the crucible can be evacuated or filled with an inert gas.
