Abstract
Process for the electrolytic pickling of continuously advancing electrically conductive material, wherein the treatment periods as compared with purely chemical treatments are to be shortened respectively the length of the treatment plant is to be shortened and wherein the attack of aggressive ions onto the electrode material is to be counteracted for the attainment of longer life expectancies, in particular of the anode. The material to be treated is subjected to at least one cathodic treatment in a first vessel and merely an anodic treatment in an immediately following vessel, and the electrical circuit between the electrodes of different polarities in successive vessels is completed by way of the material being treated. In the apparatus according to the invention at least one anode dips into one of the successive vessels, whereas all electrodes in the immediately following vessel are of cathodic polarity.
