Abstract
A pickling process of a metallic strip is provided including the steps of: passing said metallic strip through at least a pickling bath being at a temperature between 1 and 100° C., applying an alternating current, having a current density of 1x102 to 1x105 A.m−2 of unit surface of said metallic strip to said metallic strip passing through said at least one pickling bath.

A pickling process of a metallic strip comprising the steps of:
- passing the metallic strip through a pickling bath being at a temperature between 1 and 100° C.;
- applying an alternating current on the metallic strip passing through the pickling bath, the alternating current applying a current density of 1×102 to 1×105 A.m−2 of unit surface of said metallic strip to said metallic strip passing through the pickling bath, the alternating current having an anodic period and a cathodic period with a cathodic/anodic pulse length ratio of 0.1 and 5.0.
