Abstract
A process and apparatus for the electrochemical pickling of ferrous and other metal wires is disclosed. The process, which is particularly suitable for high-carbon steel wires, involves the application of a low voltage alternating current to the wires in a pickling bath containing a selected electrolyte. The frequency of the current is modified as compared with mains frequency, the modification depending on the nature of the electrolyte. The wave-form of the current may also be modified and a suitable direct current may be superimposed.
