| Abstract: | Alloy design,solidification structure,solidification sequence,phase diagram,phase transformation behavior and heat treatment characteristics of multicomponent white irons used for hot rolling mill roll are discussed here. It is showed that type and morphology of eutectic carbides can be controlled by combining alloyed elements. Phase transformation behavior obtained from CCT curves provides useful instructions for the heat treatment process. Wear-resistance of multicomponent white irons used for hot rolling mill roll is good than that of common rolls in practical use. |
