ABSTRACT:
A method and apparatus utilized in conjunction with a wire galvanizing apparatus assures a bright finish on the coated wire. This method and apparatus includes passing the wire through a water quenching bath immediately following the emergence of wire from the molten zinc galvanizing bath of a conventional galvanizing apparatus. A pair of pressure pads grips the wire at its entrance to the water quenching bath for substantially sealing the water quenching bath against water leakage into the adjacent molten zinc galvanizing bath. A heating apparatus is directed at the wire prior to its entrance to the pressure pads to assure that the zinc coating is still in a molten condition as the wire enters the water quenching bath.
