Hi Cr Steel Rolls are mainly used for rough stands (R1 & R2) of hot strip plate rolling mills and universal section rolling mills. We make this kind of roll by centrifugal cast, and the material of core is strength nodular iron. The working layer is Cr, Mo, Ni, V and other alloy element. The matrix structure is tempered martensite+carbide+ a little austenite. Becasue the microhardness of carbide is high, good wear resistance, and isolated block distribution of M7C3 type. By temperature-differential treatment, the rollers will be more wear resistance, thermal cracking resistance and high temperature performance.
