Abstract (en)

[origin: EP0621353A1] One of the faces of a metal strip forming a cathode runs past continuously at a specified speed in an electrolyte in front of the anodes (741 to 74N; 751 to 75N) which are powered by controllable rectifiers (R1 to RN) respectively. The strip is divided into length and width increments and predetermined coating ratios. A total current is determined beforehand to ensure the coatings of the increments. The control process then includes the determination of a number of rectifiers to be set in operation, the determination of an estimated current for each rectifier by dividing the total current equally among the said rectifiers to be set in operation, and the determination of current set points to be applied to the rectifiers to be set in operation. The process is cyclic for each of the faces of the strip (1). <IMAGE>
