The Calculation of Roll Force and Torque in

Equations are derived for the normal roll pressure specific roll load and torque in hot rolling mills using the condition for plastic deformation in rolling derived by Orowan together with von Kármán s equation of equilibrium Although applying strictly to the rolling of ideal plastic rigid materials these equations may be applied to the rolling of materials which strain harden by using
