ABSTRACT:
A method of dissolving zinc oxide in which, to perform continuous zinc-system electroplating of a steel sheet using an insoluble anode, particularly continuous zinc-nickel alloy electroplating, a dissolution bath is provided in a circuit for a sulfuric acid plating liquid, and zinc oxide is dissolved in the plating liquid in the dissolution bath. The amount of zinc oxide thrown in is controlled during dissolution of zinc oxide so that the pH of the plating liquid at an outlet of the dissolution bath does not exceed 2.3.
