<p>In the electroplating of strip steel (11) with zinc or zinc alloys in a strip electroplating line the steel strip (11) coated with zinc or zinc alloy exits the system via a metal conductor roll (20). Metal tends to deposit on the conductor roll. To remove such metal the conductor roll (20) is normally partially immersed in an acid bath (21) containing, for example, sulfuric acid. A problem is corrosion of the conductor roll (21) by the acid. This corrosion of the conductor roll (21) is considerably slowed by adding an oxidizing agent such as hydrogen peroxide, sodium peroxydisulfate or potassium peroxydisulfate to the acid bath in accord with the present invention.</p> |
