摘　　要：工作辊弯辊控制技术是CVC轧机极其重要的一个环节,弯辊力响应的快速性和准确性直接影响板形控制系统的性能。为消除轧制力变化和中间辊窜辊位置变化对弯辊控制效果的影响,采用轧制力前馈控制技术和中间辊窜辊位置前馈控制技术,提高弯辊控制系统的可靠性和准确性。针对因轧制力前馈补偿值过大而容易造成起车过程中浪形伤辊、边浪勒辊等问题,对轧制力前馈系数进行优化,提高了控制系统的稳定性。Work roll bending control technology is a very important part of CVC mill.The rapidity and accuracy of the bending force response play a vital role in the performance of the shape control system.In order to eliminate the influence of the change of rolling force and the change of middle roll shifting position on the control effect of roll bending,the feedforward control technology of rolling force and the feedforward control technology of middle roll shifting position are adopted to improve reliability and accuracy of the roll bending control system.In order to solve the problem that the rolling force feedforward compensation value is too large to cause roll damage by wavy edges in the starting process,the rolling force feedforward coefficient is optimized to improve the stability of the control system.
