Improvement in Setting Accuracy of Rolling Force Model During Process Control of Cold Rolling

The Bland-Ford-Hill model was used for rolling force calculation of process control of cold rolling.The plastic deformation in bite zone and elastic deformation at the entry and exit of bite zone were considered for the model calculation.The factors affecting the calculated rolling force were analyzed.Two kinds of adaptive learning way for improving setting accuracy of rolling force model were discussed.The practical application verifies that the ways can improve the setting accuracy of rolling force model obviously and the stability of the algorithm can also meet the requirement of on-line process control.
