This paper is concerned with investigations into the effect of tension between the stands of the finishing mill on width control in a hot rolling process. An analysis is given to predict satisfactorily the variation in width due to spreading and also due to strip tension between the stands. Wusatowski's model which is developed to give an account of spreading is specified and a similar model to give an account of width reduction due to strip tension between the stands is developed. It is shown that the theoretical values of the model are in good agreement with the experimental results obtained from a hot rolling line of steel strip.
