Cazzaniga Process

A hot-dip galvanizing process. Wire is led into a single degreasing/pickling tank that contains sodium hydroxide solution. Separate compartments for each reel of wire have a winding reel connected to the power supply, the electric circuit being completed through the wire to the zinc bath. The current heats the wire and the electric field surrounding the wire assists the pickling. The wire then goes into the molten zinc, followed by wiping and water quenching.
