Abstract
There is disclosed a method and a device for the continuous electrolytic deposition of metals from aqueous solutions of metallic salts onto a metal strip using a high flow speed of the electrolyte between anode and cathode in order to obtain high current densities at relatively low voltages, especially for the electrolytic coating of steel strip with non-ferrous metals, preferably with zinc. In order, particularly, in the case of a one-sided strip coating, to set and be able to regulate a very small distance between anode and cathode, these is thereby achieved low voltage losses in the electrolyte and a correspondingly lesser development of heat, while inducing a very rapid exchange of the electrolyte in the space between anode and cathode. There is obtained a high current density. Finally, not to adversely affect the industrial qualities of the strip by a very low friction of the strip to be coated, it is disclosed that the metal strip as cathode be passed along a rotating cylindrical anode and that fresh electrolytic solution be constantly introduced into the space formed between anode and cathode.
