ABSTRACT:
A roller for the continuous electrolytic processing of metallic or metallized strip materials which is a good electrical conductor is provided with a circuit for cooling fluid. It has two forged flanges each defining a hollow half shaft along a common longitudinal axis. The two flanges are made fast to the respective ends of a hollow cylindrical body. Proceding from the outer cylindrical surface of the assembly of the flanges and of the body there are provided successively radially outwards from said surface: a continuous layer of uniform thickness of a corrosion-resistant metal, a continuous layer of a metal which is a good conductor of electricity with constant cross-section for the passage of electric current, the zone of the face of the roller being also provided with an outer coating of a hard metal. The flanges may have an internal cup shape. A cooling liquid can flow through the hollow shafts.
