The hardness of high Chromium cast steel rollers can reach 65-80Hsc. Its matrix has good resistance and good resistance to fire cracking. The HCrS roller has a low carbon content range of approximately 10%. One characteristic of HCrS is that the mill does not require special water cooling conditions. During the rolling process, these rollers can form oxide films to improve the surface quality of the rolled products. These rolling mills are suitable for the early stages of b roughing and 4-roll finishing of hot-rolled strip mills.
