ABSTRACT:
A galvanizing apparatus comprising a vessel for containing a melt of molten metal. The vessel includes at least one conical projection in its side walls around which an induction heating coil is wound to generate a uniform and continuous stirring pattern of molten metal that penetrates deeply into the pot. In a second embodiment, the galvanizing vessel has no projections from its side walls, but comprises instead one or more flat inductors disposed on the exterior wall of the vessel. The flat inductor is surrounded by magnetic return shunts for directing the magnetic force field created by the inductor.
