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.
Claims5
Apparatus for obtaining a bright finish on zinc galvanized wire comprising:
- water quenching bath means for quenching the wire while the zinc coating is still in a molten condition, said water quenching means being mounted for receiving said wire following its passage through a molten zinc bath, burner means interposed between the water quenching means and the molten zinc bath and directed at the wire for maintaining the zinc coating on the wire in a molten condition until the wire enters the water quenching means, and means interposed between said water quenching means and said burner means for substantially preventing water from the quenching means from leaking into the zinc bath.
In an apparatus for galvanizing wire and including feed and take up reels for passing wire continuously through the apparatus, a molten zinc bath, means for passing the wire through the bath and means for cooling the wire prior to collection thereof on the take up reel, the improvement comprising means for obtaining a bright finish on the galvanized wire, said improvement comprising:
- water quenching bath means disposed adjacent the exit point of the wire from the molten zinc bath, means for substantially preventing leaking of water from the water quenching bath means into the molten zinc bath, and burner means interposed between said water quenching bath means and said molten zinc bath and directed at the wire for causing the zinc coating on the wire to remain in a molten condition until it enters the water quenching bath means.
