Abstract
This continuous galvanizing method and apparatus passes a linear element to be galvanized, e.g., wire, rod, or tube, through a surrounding, relatively short length of conduit which is attached as a cross-tee to the end of a delivery pipe rising from a centrifugal pump submerged in a vat of molten zinc, and continuously flooded with liquid zinc to coat the linear element. The zinc flowing from the open ends of the conduit, and falling as excess from the element being coated, drops back into the vat for recirculation. The vat is covered to provide a substantially closed operating space above the pool of molten zinc to enable the coating to take place in an inert atmosphere.
