Adamite roll is one kind of rolling materials whose performance is between steel roll and iron roll. It contains Ni, Cr and Mo elements, its matrix contains certain quantity of carbide which is processed with special thermal treatment technique with high abrasive resistance, strong toughness and good thermal resistance, its special characteristics is that there no hardness difference in working layer, applicable to rough milling and initial section of finishing mill for Tandem mill with steel; rough and medium milling of rod and wire milling machine, pre-finishing rack, universal mill, roll collar and roll jacket of cantilever mill.
