The research and application of the rolling force model for 4-stand tandem cold strip mill

The traditional rolling force model of 4-stand tandem cold strip mill at Anshan Iron and Steel Corporation was analyzed, and some defects were found out. On the basis of theoretic analysis and experiment, the new rolling force model has been developed. Comparing results of the measured rolling force with the calculated value from the traditional model and also with the calculated value from the new model show that the calculating precision of the new model is better than that of the traditional model. The new rolling force model has been applied to optimal desigh of back up roll shape scheme and the development of new rolling scheme, and good results have been got.
