ABSTRACT:
A melting furnace includes a body of a refractory material having a hollow melting portion for holding a molten material and a hollow heating portion disposed adjacent thereto for holding the molten material and maintaining the molten material at elevated temperatures. The melting portion has at its upper portion an opening through which a material to be melted is fed into the melting portion, the body having a pair of generally horizontally-spaced inlet and outlet ports each communicating the melting portion with the heating portion. An electromagnetic agitator is disposed below the melting portion for producing a shafting magnetic field in the melting portion which magnetic field shifts from the inlet port to the outlet port to thereby cause the molten material to move from the melting portion to the heating portion via the outlet port and then to move from the heating portion to the melting portion via the inlet port.
