>The Calculation of Roll Force and Torque in Hot Rolling Mills
Abstract. 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 ...

>Energy Management in Small and Medium sized Re-rolling mills
In the re-rolling mills, normally the 3-phase electric induction motor of high horse power is used due to the fact that the flywheel requires high torque to be driven initially. Once the flywheel stores sufficient torque which is required at the start up, the flywheel then requires less torque than what is required initially.
