In recent years, steel makers have been promoting new plating lines and the additional equipment according to the rapidly increasing demand of the surface treatd steel sheet for the automobile body. Especially concerning the electroplating equipment, the structure of the electroplating cell has influence on the expense of the equipment and the running cost. On this report, our purpose is to increase the current density and reduce the voltage for developing the high efficient electroplating cell of horizontal type. In order to achieve above purpose, the electrode is devided into two parts, then the gas which evolves by the electrolysis is removed efficiently from the cell, at the same time, the practical current density increases drastically. And more, the catenary and the irregular shape of strip are prevented by setting the liquid cushion nozzle in the cell due to the static pressure, then the distance between strip and the electrode is reduced. Therefore the voltage drop by electroplating is reduced and it becomes possible to apply the high current density. By this development, the high efficient electroplating becomes possible.
