ABSTRACT:
A process and apparatus are provided for producing an electrolytically coated, hot-rolled steel strip without any intervening strips. The apparatus includes a chemical pickling section being combined in one line with an electrolytic coating section containing electrolytic cells so that the pickled steel strip is fed directly to the electrolytic coating section without any intermediate steps. The spent electrolyte solution from the electrocoating section to the pickling section to pickle the steel. The spent pickling acid can also be used to generate the electrolyte solution that is fed to the electrocoating section.
