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+ alittle austenite. Because the microhardness of the 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.
