Cold Rolling of Steels – IspatGuru

Oct 08, 2014· Each mill stand has vertically stacked rolls that are powered by huge motors to impart high compressive stresses into the strip. Mill stands can be 2- high, 4-high or six-high. 4-high stands are more widely used since they give maximum advantage over other two types. Single or two stands cold rolling mills are normally reversing mills.
