Fundamental concept of metal rolling - mtixtl.com

plastically during rolling. 4) The volume of metal is constant before and after rolling. In practical the volume might decrease a little bit due to close-up of pores. 5) The velocity of the rolls is assumed to be constant. 6) The metal only extends in the rolling direction and no extension in the width of the material.

The Calculation of Roll Force and Torque in Hot Rolling

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
