Abstract: PURPOSE:To prevent the damage of a primary coil and improve the durability of a furnace by a method wherein refractory material having non-reactive property against molten metal is employed for an outside refractory material layer which is in contact with the molten metal while permeation resistant refractory material, through which the molten metal is hardly permeated, is employed for the inside refractory material layer. CONSTITUTION:In a groove type induction furnace, in which a primary coil 4 arranged on the bottom of the inside of the furnace is excited by AC current to generate induction current in molten metal 1 in the outer peripheral groove 6 of the primary coil and heat the molten metal through the resistance thereof, magnesia refractory material is used for an outside non-reactive refractory material layer 2 while high-alumina refractory material is used for an inside permeation resistant refractory material layer 3. The non-reactive refractory material is used for the outside layer 2 in contact with the molten metal in such a manner whereby slug will never be generated on the surface of the refractory material and the molten metal will never be permeated into the inside of the layers even when the molten metal is permeated through the refractory material and arrives at the inside refractory material layer 3 since the inside refractory material is prominent in permeation resistant property. Further, the amount of molten metal arriving at the inside refractory material layer 3 is small even when the slug is generated whereby the slug is formed on the surface of the layer as a thin film and thick film of the same will never be produced. Accordingly, the damage of the primary coil 4 can be prevented.
