in this paper, the rolling force and reduction ratio have been investigated in multilayer strip rolling. for this purpose, two different set of multilayers have been selected which are al/st/al and cu/al/cu layouts. at first, the validation of the numerical analysis was performed by using an experimental test. after validation of the numerical results, two set of multilayer layouts were simulat...

A new model for the asymmetrical rolling is proposed to calculate minimum rollable thickness simply and fast by slab method. The calculation formulas of pressure, force, critical roll speed ratio, front tension under different deformation zone configurations are proposed, configuration-rolling parameter relationship diagram given analyzed. results show that can be reached when parameters keep c...

Cold rolling of steel is one of the most important metal forming processes so an accurate control of its parameters during the process is necessary. In this paper, the friction coefficient has been proposed as a function of cold rolling parameters such as forward slip, forward and backward tensile stresses ,strip thickness, static deformation, resistance of strip before and after rolling ,strip...
