| Abstract: | Based on the loss efficacy analysis for mill roller booned, the relations of carbon conted, alloying constitued, heat-treatment technological process, mechanical properties, Ar%, CVF and Cr/C of Cr20 series high chromium cast iron and its wear resistance are studied by a MPS model all. The hot composition, hardness and microstructure are defined. The testing results show that the service life of all roller with this new material reaches advance world level. |
