Abstract

Method for applying a metallic coating to a ferrous base metal strand wherein the surface of the strand is first thoroughly cleaned to render it receptive to a molten coating metal. During the cleaning step, the strand may be heated to a temperature less than the melting point of the metallic coating metal. A non-conductive coating pot is provided which has a primary coil within its side walls. Power is supplied to the primary coil which induces heavy secondary currents in the coating metal within the pot. This current is converted into heat by resistance of the coating metal itself, thereby supplying a high quantity of heat directly in the coating metal. The induced secondary current constantly stirs the molten coating metal so as to help provide a bright bath surface where the strand exits from the bath, and minimizes accumulation of oxides and dross.
