Dimensional control of the work-piece in steel industry is of important interest. The main aspects in overcoming the thickness control are variations in material strength due to variations in chemical composition, work-piece temperature, reduction and the strain rate applied to the work-piece. In this paper based on the main parameters affecting the rolling force an attempt been made to give a more accurate prediction for the flow stress in a steel rolling finishing mill. Predicted values of the model are compared with those of the experimental values which are shown to be in good agreements
