Abstract

Method and device for electrolytic, continuous treatment of a continuously formed material (1) of stainless steel, said material being made to run in an electrolyte (34) between electrodes (35, 36) lying in series, under the influence of a direct current with alternating polarity, every other electrode being anodic and every other being cathodic and every electrode being matched by an electrode of the same polarity on the opposite side of the material (1), an oxide surface layer being removed from the material in the method. According to the invention, said electrodes (35, 36) lying in series are partially, electrically insulated from each other in the electrolyte (34) by partial insulators (37) being arranged between after each other arranged electrodes of opposite polarity, preferably both on a first side and on a second side of the material (1).
