Abstract
An arc is struck between one or more auxiliary electrodes surrounded with flux and the base of the ingot mould which has one or more cavities in which the molten slag produced is rapidly heate to a high temp. and progressively augmented by the supply of powdered flux until the slag bath comes into contact with one or more remelting electrodes arranged in the ingot mould.
