　　跑偏是铝板带在强压变形下宽度方向逐渐失去横向对称性，中心线偏离并急剧扩大的横向失稳演变过程。跑偏会引起铝带拉断、卷取时不对中、工作辊损伤等，跑偏严重时还会引发安全事故，造成停产。在板带轧制过程中，轧件尾部由于缺少张力控制，容易产生跑偏。针对轧件跑偏，采用回归分析方法，建立轧制力差和跑偏量之间的线性回归模型，得到稳定轧制的轧制力差区间。对于偏离稳定轧制力差区间的轧制过程，给出调整轧机两侧辊缝差进行纠偏的调整模型。通过对工业现场工艺条件和运行数据分析，轧件尾部跑偏以F3，F4机架跑偏较为严重，利用MATLAB软件对F3，F4机架尾部进行仿真，验证跑偏模型的准确性。

Deviation of a strip is represented by the distance between the center of the strip and the center of a roll .For various asymmetrical factors in rolling process ,the transverse symmetry of the strip width direction under the extreme pressure gradually lost .Accompanied with rapid transverse instability evolution ,the center distance between the strip and roll will increase .Devi-ation of a strip in the hot rolling process is an important unsolved technical problem .It results in reduced productivity and in some extreme cases ,leads to strip tearing and work roll injury .Due to the lack of tension control in strip tail rolling process ,it is easy to produce deviation .For the strip deviation ,the linear regression model between rolling force differences and the amount of deviation was established ,so that the stable interval of rolling force difference was found .In the tail deviation process ,the adjustment model of controlling the roll gap differences was proposed . Through the analysis of process conditions and operating data on the industrial scene ,the tails of the rolling deviation F3 ,F4 rack deviation are more serious .Thus ,the simulation based on F3 ,F4 rack is conducted using MATLAB software to validate the accuracy of this deviation model .
