Abstract: (5919 Views)
In this paper, an analytical method based on Modified Slab Method of analysis is presented to study the asymmetrical rolling process due to difference in work rolls radii, rolls speeds and interface frictions. The shear force imposed on material along the contact region is considered to be a function of the frictional factor and the roll gap geometry. Elastic-plastic with linear work hardening constitutive law was assumed. Asymmetric factors considered are roll diameter ratio, roll speed mismatch and differential interface friction conditions. Neutral points’ location along the contact region in relation to the
variations on thickness reduction, roll speed ratios, roll diameters ratio and front and back tensions are investigated. Predicted values for rolling force and torque from the present analytical model are compared with those of other workers, which are shown to be in good agreement
