In this paper based on Modified Slab Method of analysis for rolling of clad sheet or double- layers sheets where the two layers are bounded prior to rolling is given. This model considers the general case of asymmetrical rolling due to unequal surface speed, different contact friction, roll diameters, flow stress and thickness ratios of the two layers. Using this model rolling parameters such rolling force, torque and the developed curvature of bimetallic plate with respect to reduction in thickness can easily be calculated. The analytical rolling force and curvature from the proposed model were compared with the analytical result of other investigators which are shown to be in good agreements.
