摘　　要：分析了中厚板轧制过程中两侧辊缝差、轧件入口横向楔形、轧件两侧温度差和轧机两侧刚度差对中厚板两侧厚度偏差的影响。根据实时检测的轧制力、辊缝等数据,利用轧机刚度和轧件塑性系数推导了消除侧弯的两侧辊缝在线自动调整模型。该模型在国内某3500 mm轧机上进行在线应用,40 mm以下成品钢板两侧厚度偏差控制在0.12 mm以内,消除薄宽规格钢板的刮框事故,轧后钢板的侧弯得到有效控制。The effects of bilateral gap deviation,entry transverse taper of plate,bilateral temperature deviation of plate and bilateral mill stiffness deviation on the bilateral thickness deviation of plate in rolling process was analyzed.According to the data of real-time measurement of rolling force and roll gap,online automatic adjustment model of bilateral gap for eliminating camber was derived by using the stiffness of rolling mill and the plasticity coefficient of rolling piece.The model was applied on a 3500 mm rolling mill,the thickness deviation on both side of plate was controlled within 0.12 mm for less than 40 mm plate.The frame scratching accident of the thin and width specification plate was eliminated,and the camber was effectively controlled.
