    Cold rolling differs from hot rolling in that the rolling loads are usually much higher. Factors like dimensional control, mechanical properties, and surface finish gain in importance. Cold rolling mills also operate at considerably higher rolling speeds of sometimes above 2,000 m/min, and entry and exit tensions are applied to the strip to assist the deformation. In the cold rolling operation Rolling can be classified as Hot Rolling or Cold Rolling. Hot rolling is carried out above RCT and cold rolling is carried out below RCT.
