对于带钢热连轧机的厚度控制,常规的监控AGC在头部厚度设定出现较大偏差时,为迅速纠正偏差,缩短超差长度,通常会在出口机架进行快速大幅调整,这对于轧制过程的稳定性、板形控制等都是不利的。基于保持负荷分配比例不变的思想,提出了快速监控AGC方法,并给出了具体的计算模型和计算方法。应用情况表明,该方法可以显著提高厚度精度、平衡轧机各机架负荷,达到了预期效果。 For the strip thickness control of hot strip mill, conventional monitoring AGC in the head thickness setting a larger deviation, in order to quickly correct the deviation, shorten the length of tolerance, usually in the export rack for rapid substantial adjustment, which is rolling The stability of the system process, shape control, etc. are adverse. Based on the idea of ​​keeping the proportion of load distribution unchanged, a fast monitoring AGC method is proposed and a specific calculation model and calculation method are given. The application shows that this method can significantly improve the thickness accuracy and balance the load of each rolling mill and achieve the expected result.
