摘　　要：宽厚板轧机在轧钢过程中,因两侧压下螺母压缩变形量不同,导致两侧压下装置垂直方向出现位置偏差。通过研究压下螺母受载后正常弹性变形与异常变形的区别,可以判断压下螺母变形是否正常,发现异常时在轧机操作画面发出报警并及时处理,防止因压下螺母异常变形造成位置偏差,提高两侧压下装置位置精度,保持轧机的稳定性,改善钢板质量,达到提高成材率的目的。In the process of rolling steel in wide and heavy plate mill,due to the different compression deformation of the screwdown nuts on both sides,the vertical position deviation of the screwdown devices on both sides occurs.By studying the difference between normal elastic deformation and abnormal deformation of the nut under load,we can judge whether the deformation of the nut is normal,the system can display an alarm on mill operator HMI and take actions at any abnormal deformation to prevent the position deviation caused by abnormal deformation of the nut,increase the position accuracy of both sides,maintain the stability of the rolling mill,improve the quality of the steel plate,and achieve the purpose of higher yield rate.
