ABSTRACT:
In a method of intermittently charging a molten principal raw material and any supplementary material as needed to provide a specified raw material formulation into a melting furnace and continuously discharging a molten material therefrom, the discharge of the molten material is effected by determining the weight of the tiltable melting furnace, said weight changing with change of the raw materials and discharging of the molten material, computing the rate of change in weight of the molten material with respect to time from the determined weights of said furnace, and tilting said furnace to a position indicated by comparison of said computed rate of change in weight of the molten material with respect to time and the set rate of change in weight of the molten material with respect to time.
