摘　　要：基于中厚板可逆轧制的特点,利用道次间隙时间,采用2种方法进行轧件厚度偏差的修正,一是利用自然刚度来消除送料厚度的偏差;二是修正变形抗力模型的计算精度来调整后续道次的辊缝设定值。该方法已成功用于首钢中厚板厂3340mm轧机。Based on the reversible feature of plate rolling process,the plate gauge deviation can be reduced at pass space time by two methods.One is to use the rolling mill stiffness to eliminate the gauge deviation by roughing mill.The other is to use pass recalculation program to correct the parameter of resistance force of deformation model and modify the gap setup value.These methods got good effect by online application at Shougang 3340mm plate mill.
