Abstract
A method and a device for performing the method of electrolytic pickling of a metal strip. The metal strip continuously passes through an electrolyte bath which has an electrolyte circulating through a closed system. Crevices are formed on both sides of the metal with electrodes which are located above the top crevice and below the bottom crevice. The electrodes are of opposite polarity and are chemically resistant to the electrolyte. An electrical current is passed from one electrode, through one crevice, through the metal, through the other crevice and to the other electrode which results in the electrolytic pickling of the metal.
