ABSTRACT:
Method and apparatus for electrogalvanizing one or both sides of a steel workpiece are disclosed. A series of insoluble apertured plating anodes are positioned in spaced relation to the workpiece. When one side is to be plated one or more anodes are preferably mounted above the strip and when both sides are plated, anodes are mounted both above and below the strip. Solution is pumped through the holes in the anodes to momentarily contact the workpiece and they fall into a sump to be recirculated. A potential difference between the anode or anodes and the workpiece causes current flow through the electrolyte solution to electroplate the workpiece. Solution collection by the sump is directed to a reaction station for replenishment of the zinc metal ion. The solution is then filtered back to a main reservoir tank from which it is again pumped to the plating anodes.
