轧件宽度对热轧带钢轧机弹跳的影响

 轧机的弹跳方程是AGC控制系统不可缺少的模型，但轧制过程中轧机的实际弹跳与轧件的宽度有关，当轧件宽度显著偏离全辊面宽度时，轧机的弹跳也会严重偏离预压靠方法得到的结果。采用影响函数法分析了轧件宽度对轧机弹跳的影响，计算结果表明随着轧件宽度的减小，轧机弹跳宽度补偿量增加；随着轧制力的增加，轧机弹跳宽度补偿量增加。根据影响函数法计算结果，建立便于工程应用的轧机弹跳宽度补偿回归模型。

Influence of Workpiece Width on Hot Strip Mill Stretch

Mill stretch equation is an indispensable model for AGC system. The mill stretch is changed with strip width during rolling process. The actual mill stretch deviates from that measured with “mill kiss” method, when the strip width deviates from work roll face width. The influence of strip width on mill stretch was analyzed with influence function method, and the results show that mill stretch width compensation increased with strip width decreasing or rolling force increasing. A mill stretch width compensation regression model was developed for on line application.
