A galvanizing apparatus (1) for heating liquid metal coatings comprises a vessel (10) for holding molten metal (5), said vessel having a bottom and vertical side walls (12), said side walls having interior and exterior surfaces and at least one coreless induction furnace (20). The coreless induction furnace is comprised of a conical projection outward from the vessel side walls, the projection being formed in both the interior and exterior surfaces of the side walls such that both the interior and exterior surfaces of the side walls form an outward projection having a conical shape. At least one conical projection has a wide radius adjacent to the side walls. The radius decreases along the outward projection from the side walls, and at least one induction heating coil (24) for heating and stirring the molten metal is helically wound on the conical projection on the vessel exterior such that the induction heating coil takes the shape of the conical projection. <IMAGE> |
