本发明公开了一种宽厚板两侧厚度偏差的控制方法，通过测量轧机两侧轧机标定的轧制力、辊缝数据和轧制过程实时记录的轧制力、辊缝等数据，利用轧机弹跳方程、轧机刚度和轧机塑性系数推导宽厚板两侧厚度偏差调整模型，可根据实时检测的轧制力进行辊缝调整量的计算，计算的辊缝调整量按照调整系数k补偿到轧机非传动侧液压辊缝，按照-( 1-k )补偿到轧机传动侧液压辊缝，通过轧机液压控制系统实现辊缝的动态调整，减少并消除各影响因素对轧件两侧厚度偏差的影响，提高钢板横向厚度精度，减少钢板同板厚度偏差，避免钢板横向楔形和钢板的侧弯。

The invention discloses a control method for the thickness deviation on both sides of the wide and thick plate. By measuring the rolling force and roll gap data calibrated on both sides of the rolling mill and the rolling force and roll gap data recorded in real time during the rolling process, the rolling mill bounce equation, rolling mill stiffness and rolling mill plasticity coefficient are used to deduce the adjustment model for the thickness deviation on both sides of the wide and thick plate. According to the real-time detection of rolling force calculation of the amount of roll gap adjustment calculation of roll gap adjustment quantity according to the compensation adjustment coefficient k to the rolling mill drive side hydraulic roll gap, according to the - (1 - k) compensation to the rolling mill drive side hydraulic roll gap, through the rolling mill hydraulic roll gap control system of dynamic adjustment, reduce and eliminate the influence factors on the effect of rolling piece thickness deviation on both sides, Improve the accuracy of the transverse thickness of the steel plate, reduce the deviation between the thickness of the steel plate and the thickness of the steel plate, avoid the transverse wedge of the steel plate and the lateral bending of the steel plate.
