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 Krmns equation of equilibrium. Although applying strictly to the rolling of ideal plastic-rigid materials, these equations may be ...

The ratio a/Lp a/R.t is used to calculate the moment arm a 0.5 for hot rolling and 0.45 for cold rolling. The torque is equal to the product of total rolling load and the effective moment arm. Since there are two work rolls Torque Mt 2P.a Consider two high roll mill as shown in the figure.
Apr 01, 2012 However, the accurate roll torque and roll separating force for broadside rolling in a roughing sequence are the prerequisite for the automatic control of the rolling mill , . Motivated by the information above, the present paper proposes an analytical solution to the total power functional for broadside rolling.
