Abstract (en)

[origin: WO9749843A1] The invention discloses a method for the electrolytic coating with a metal layer of the casting surface of a cylinder for the continuous casting of thin metal strips between two cylinders or on a single cylinder. The said casting surface is immersed at least partially in an electrolyte solution containing a salt of the metal to be deposited, opposite at least one anode, the said surface is placed in cathode position and a relative motion is created between the said casting surface and the said electrolyte solution, characterised in that insulating masks are inserted between the said anode(s) and the edges of the said casting surface, thus avoiding a concentration of current lines on the said edges and in their vicinity. The invention also concerns an installation for the electrolytic coating with a metal layer of the casting surface (3) of a cylinder for the continuous casting of thin metal strips between two cylinders or on a single cylinder, comprising a vessel (1) containing an electrolyte (2) containing a salt of the metal to be deposited, means (5, 6) for immersing at least partially in the said vessel (1) the said casting surface (3) and for creating a relative motion between the said casting surface and the said electrolyte, at least one anode (4, 4') set in the vessel (1) opposite the said casting surface (3), and means for bringing the said casting surface to a cathodic potential, characterised in that it comprises masks (7, 7') made of an insulating material inserted between the edges (12) of the said casting surface (3) and the said anode(s) (4, 4'), the said masks (7, 7') preventing a concentration of current lines on the said edges (12).
