摘要： Disclosed is a method for electroplating a steel strip by arranging a plurality of electrode rows each consisting of a plurality of electrodes disposed adjacent to each other along the direction of width of said steel strip in opposition to said strip travelling in an electrolytic cell holding an electrolytic solution, so that a metal constituting said electrodes may be electroplated on said steel strip, comprising the steps of intermittently or continuously transferring said electrodes of said electrode rows in a direction perpendicularly to the direction of travel of said steel strip at a speed so that a distribution of a deposition amount of the metal of said electrodes along the direction of width of said steel strip may be kept within an allowable tolerance, a width of said electrode rows being greater than the width of said steel strip; and unloading said electrode from one end of one of said electrode rows transferred by said transferring step and loading said electrode to the other end of said one electrode row or to an end of another of said electrode rows.
