摘　　要：针对北冶公司四辊可逆热轧机带钢纵向厚度公差波动较大问题,本文从电气控制角度,提出了在该轧机液压控制系统加入AGC控制内环,通过编写PLC控制算法程序,调整PID控制参数等改进方法,运用iba数据采集软件监控该轧机现场运行数据,带钢纵向厚度公差过大问题得到明显改善。In order to solve the problem of strip longitudinal thickness tolerance fluctuation of Four-high reversing hot rolling mill in Beiye company.From the point of electrical control,this paper puts forward the way of adding AGC control inner loop in the hydraulic control system of the rolling mill,by programming PLC control algorithm and adjusting PID control parameters,etc.Iba data acquisition software was used to monitor the mill operation data and the problem of excessive longitudinal thickness tolerance of strip was obviously improved.
