Abstract

Results of theoretical investigation of rolling process parameters when using one-roll drive are presented. Effect of reduction, roughness of rolls and rolling rate on the friction coefficient, forward slip and average normal contact stress at symmetric and asymmetrical rolling (with one power-driven roll) is shown. The possibility to use one-roll drive on the sections of unsteady-state processes for improvement of strip quality and reduction of metal waste is shown.
