摘　　要：根据国内某1220冷连轧机组生产实际情况,采用逆流直接求解非线性方程组的方法建立起变断面、变张力冷连轧机组动态变规格控制系统,得到变规格过程中各个过渡段各个机架的辊缝、辊速变化值及变规格轧机调整时间·生产实践表明,带钢在变规格过程中的厚度偏差及偏差长度优于设计要求,在变规格过程中各种轧制参数具有较高的稳定性·?The Flying Gauge Change (FGC) control system of different cross sections size and different tension for tandem cold mill was developed. According to actual production condition of tandem cold mill, reversed flow control and nonlinear system of equations were adopted to the setup FGC system and then, the roll gap,roll speed, and mill regulation time of transit stage were calculated for every stand. An application of the system on actual production line showed that the strip thickness deviation and the strip length with deviation are better than design requirement during FGC. The rolling parameters are also stable during FGC.
