ABSTRACT:
A method of continuously melting a material comprises the steps of depositing carbon in a crucible furnace provided with a melt outlet and an inlet in an upper portion thereof, heating the carbon by electromagnetic induction heating by an electromagnetic coil provided around the outer periphery of the furnace, continuously supplying the material to be melted onto the heated carbon through the inlet and melting the material to be melted by electromagnetic induction heating so as to cause a melt to continuously flow out of the furnace through the melt outlet. The temperature of the melt flowing out of the furnace is adjusted by controlling the ratio between the quantities of heat supplied by the electromagnetic induction heating to the carbon and to the material to be melted.
