Abstract

The backup rolls are used with work rolls and their service period is much longer than work rolls. The backup roll affects the control ability of the mill for profile and flatness of products and roll contact pressure. If the backup roll contour is not appropriate, there will be a non-uniform roll contact pressure and the peak value of roll contact pressure may be large. According to the actual situation of a 1800mm CVC mill, combined with the typical wear condition of backup roll, A 3D finite element model of roll system was established. The roll contact pressure is analyzed with the model, and the improvement method of backup roll contour is proposed. With the improved backup roll contour, the non-uniform level of roll contact pressure drops by 18.2% and the peak value of roll contact pressure descends by 19.1%. All these can reduce the consumption of backup roll and the risk of backup roll spalling effectively.
