Compared to ordinary high Cr cast iron rolls, the enhanced ones add modification treatment and applied to work rolls for roughing/finishing stands of 4-high medium, wide plate mill, work rolls for roughing/finishing stands of 4- high hot wide strip mill, work rolls/back-up rolls for tempering stands of 4-high cold and hot strip mill. The modification treatment limits oxidation of the roll surface, concurrent occurrence with the banding and spalling in adverse thermal.
environment. The improved surface in the rolling cycle cause less scale spalls off the roll and is less sticky onto the rolled strip. less mill scale and less potential damage lead to smaller quantity of grinding that prolongs the service period. Therefore, the roll life is prolonged and longer roll campaign and less number of roll-change are achieved.
