ABSTRACT:
A roll, comprising cemented carbide and cast iron. The roll may be used for hot or cold rolling. The barrel comprises one or several cemented carbide rings, cast by centrifugal casting method into a roll body of an iron alloy. The casting alloy comprises an essentially graphitic cast iron, which after the casting contains residual austenite. This residual austenite is transformed at subsequent heat treatment step (or steps) totally or partly to mainly bainite under volume increase, with the aim of reducing or totally eliminating the differential shrinkage between the cast iron and the cemented carbide as a result from cooling after the casting. The central part of the roll body may alternatively consist of another alloy.
