Abstract
A method for annealing and galvanizing wires which comprises induction heating the wires in a first chamber at a first higher temperature to anneal the wires, cooling the wires to a second lower temperature in a second chamber and galvanizing the wires in a third chamber. The chambers are in serial communication and the heating, cooling and galvanizing steps are effected in an oxygen free atmosphere.
