ABSTRACT:
A cooling roll for producing quenched thin metal tape from molten metal by the twin-roll method. The roll is made of copper or copper alloy, and the roll surface is covered with a first layer of nickel plating 0.2 to 0.6 mm thick and a second layer of chromium plating 0.02 to 0.05 mm thick. The roll has the surface which does not suffer from deformation, seizure, winding, roughening, wear, and cracking. Thus the roll can produce quenched thin metal tape with a smooth surface in a stable manner for a long time.
