Cold rolling is a metalworking process that involves reducing the thickness of metal sheets or strips through mechanical means at room temperature. Unlike hot rolling, which occurs at high temperatures, cold rolling allows for enhanced mechanical properties and better surface finish. The 20% Hi Cold Rolling Mill employs a specific configuration where the rolls are positioned at a 20% angle to the horizontal plane. This design is instrumental in achieving greater reduction ratios and improved material characteristics.
