Relations are presented to determine the rolling pressure and forward tension on strip during its asymmetric cold rolling. The relations account for the reduction and strain-hardening of the strip, unit frictional forces, the difference between the peripheral velocities of the work rolls, and the tension on the ends of the strip. Lowering the pressure of the strip metal on the rolls helps save energy, increases mill productivity, improves the quality of the rolled product, and reduces the metal content of the equipment.
