Abstract

The present invention. discloses a roll ring for hot and/or cold rolling. The rolling track comprises one or several cemented carbide rings which are cast into a casing made by an iron alloy.
the cast alloy comprises a materially graphitic cast iron, which contains residual austenite after the casting. This residual austenite is at subsequent heat treatment or treatments partly or totally transformed under volume increase to mainly bainite 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.
