METHOD FOR PRODUCING METAL PLATE HAVING ALLOY PLATING LAYER

摘要

Provided is a method for producing a metal plate having an alloy plating layer, which comprises a step wherein electroplating is carried out in a plating bath by having a metal strip continuously passed through the plating bath that is provided with an anode and a plating liquid that contains two or more kinds of metal ions for forming the alloy plating layer. This method for producing a metal plate having an alloy plating layer is characterized in that an anode which is obtained by mixing two or more kinds of metal pellets respectively formed of metals that form the alloy plating layer is used as the above-mentioned anode. This method for producing a metal plate having an alloy plating layer is also characterized in that the mixing ratio of the metal pellets that constitute the anode is determined according to the total surface area ratio of the metal pellets in the anode, at said total surface area ratio the dissolution ratio of the metal pellets that constitute the anode corresponding to the weight ratio of the metals that constitute the alloy plating layer.
