Analysis of Rolling Process for Clad Sheet Using the Modified Slab Method
Author
Abstract
In this paper, an analytical model based on Modified Slab Method is presented for rolling of clad sheet or double-layers in which the two layers are bounded prior to rolling. 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 as pressure distribution along the arc of contact of the rolls and the clad sheet, rolling force, and torque with respect to reduction in thickness can be easily calculated. The analytical rolling force and torque computed by the proposed model were compared with the analytical results of other researchers and were shown to be in good agreement. The proposed model is very suitable for online control application due to its completeness and its capability of predicting the rolling parameters
