CASTING MATERIALS FOR WORKING REGION OF INDEFINITE ROLLERS, METHOD FOR PRODUCING AND PROCESSING THE SAME, AND INDEFINITE TANDEM ROLLER

摘要

A method for the production and processing of alloyed casting material for a working part of an indefinite chill roll, a corresponding casting material and a composite indefinite chill roll incorporating the casting material. The method comprises providing a melt of a certain composition, casting the melt and subjecting the resultant body to a heat treatment. The composition of the melt is adjusted so as to afford a certain graphite and carbide distribution.
