| 摘 要： | 由于对冷轧薄板质量要求的提高,液压AGC已经成为提高冷轧带钢成品精度必不可少的手段。然而对于支撑辊采用油膜轴承的冷连轧机来说,其轴承油膜厚度随着轧制力和轧制速度的变化而变化,这将影响轧件的轧出厚度,造成厚差。尤其对冷连轧机,各机架的累积误差会使成品带的超差更加严重。以某五机架冷连轧机为研究对象,由生产现场实测数据回归出适合于实际控制的油膜补偿模型,提出适合于分布式计算机控制的控制策略,并将其应用于实际轧制过程中对油膜厚度变化进行补偿。实验结果表明:加入油膜补偿控制后,成品带钢厚差带头带尾超差段有较为显著的减少,且超差值也有所降低。

| Abstract: | Since the request to the quality of cold rolling sheet strips is higher,the hydraulic AGC(Automatic Gauge Control) has become the indispensable means which improves the product precision of cold rolling strips.However,to the tandem cold rolling mill which backup roll adopts the oil film bearing,the thickness of oil film changes with different rolling force and rolling velocity,which influences the exit thickness of strips and brings the thickness deviation.Especially for the tandem cold rolling mill,the acc... |
