Abstract:
A process for electrolytically coating the casting surface of a roll for the twin-roll or single-roll continuous casting of thin metal strip with a metal layer, comprising the steps of at least partially immersing said casting surface in an electrolyte solution containing a salt of the metal to be deposited, said surface being placed at a cathode so as to face at least one anode, providing an electrical current between said cathode and anode, and providing a relative movement between said casting surface and said electrolyte solution, wherein insulating masks are interposed between said anode or anodes and arrises of said casting surface to prevent a concentration of lines of current on said arrises and in their vicinity, said masks being interposed such that no substantial overlap occurs between a surface of said masks and a surface of said roll.
