Abstract:
A system for annealing and galvanizing wires which comprises:a first oxygen free chamber, a chamber having an upstream end and a downstream end, the upstream end comprising an upstream plate having at least one upstream aperture therein and the downstream end comprising a downstream plate having at least one downstream aperture therein; and at least one tube adapted to receive at least one of the wires and having an induction coil associated therewith disposed within said chamber, said tube being in registration with said upstream and downstream aperture, said tube being adapted to induction heat and anneal at least one of the wires at a first temperature; a second oxygen free chamber downstream of said first oxygen free chamber, said second oxygen free chamber adapted to receive and cool the wire to a second temperature; and a third oxygen free chamber downstream of said second oxygen free chamber, said third oxygen free chamber adapted to receive and galvanize the wire, said first, second and third oxygen free chambers being in serial communication.
