摘要： Steel strips are electrogalvanized with a Zn-Ni alloy deposit having the desired nickel content in a consistent manner for a long time by placing separate Zn and Ni soluble anodes in a chloride plating bath comprising major proportions of ZnCl.sub.2 and NiCl.sub.2 in an Ni/(Zn+Ni) ratio between 0.08 and 0.20 and a total molar amount of Zn+Ni of from 1 to 4 moles per liter, and b mole per liter of KCl and a mole per liter of NH.sub.4 Cl as shown in FIG. 8; passing a steel strip through the bath; and introducing currents to the soluble Zn and Ni anodes in a specific ratio given by equation (2).

摘要： A counter flow device for a plating apparatus including a rotary drum with its substantially half part immersed in a plating solution in a plating bath, about which a metallic strip to be plated passes in synchronism with rotation of said rotary drum and anodes spaced apart by radial gaps from the strip for causing electric current to flow between the strip and the anodes. According to the invention the counter flow device comprises a bottom nozzle arranged at a bottom of the bath and directing in a direction substantially opposite to an entering direction of the strip thereat and a top nozzle having a nozzle opening whose tip end is immersed in the proximity of a surface of the plating solution at a location where the strip leaves the plating solution, thereby ensuring uniform counter flows over entire gaps between the metallic strip and anodes to remarkably increase critical current density in plating and advantageously realize uniform plating.

摘要： An electrode support device for a continuous electroplating bath includes current supply rotating drums whose parts are immersed in the electroplating bath, a metal strip to be plated being trained about the immersed parts of the rotating drums, and a number of arcuate consumable electrodes arranged side by side along generators of the rotating drums and successively movable on support surfaces of electrode supports so as to supply new consumable electrodes at one ends of the arranged electrodes and remove consumed electrodes from the other ends. According to the invention, the support device comprises adjusting means for adjusting the electrode supports to remove any unevenness of gaps between the metal strip and the consumable electrodes, thereby preventing failures due to unevenness of the gaps resulting from unavoidable irregular wear on support surfaces of the electrode supports and externally adjusting the gaps to meet electrolytic conditions to eliminate edge-overcoating which would occur when the width of the strip changes to be wider.
