  • The Calculation of Roll Force and Torque in Hot

    2017-11-1  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 ...

    2010-1-5  Most of the deformation source in hot strip rolling is in the adhesion zone, where the contact stress depends on the resistance to pure shear. If this finding is taken into account, the rolling force and power may be calculated with much greater accuracy. On that basis, effective operating conditions for broad-strip mills may be developed.
