Chromium-plated roll has better surface hardness and wear resistance, and has longer service life than ordinary work roll. Although the surface roughness of chrome-plated roller and ordinary roller will have a great decline in the early stage of use, the chrome-plated roller can still maintain a large roughness. Compared with ordinary rolls, the quality of products produced by the mill using chrome plated rolls will be better. The coating will also improve the adhesion resistance and reduce the probability of replacing the roller due to the presence of foreign matters on the surface of the roller.
