以变截面、变张力逆流求解非线性方程组动态变规格控制方式为基础 ,通过轧辊速度及带钢出口速度的实测值来动态修正变规格过程轧辊速度的设定值。实际应用表明 ,轧辊速度的动态设定可以保证变规格过程中冷连轧机组各机架速度的稳定和使机架间张力稳定 ,从而保证变规格过程带钢厚度精度
On the basis of the control method of dynamic variation of non-linear equation system with variable section and variable strain countercurrent, the set values of roll speed in variable specification process are dynamically corrected by the measured values of roll speed and strip exit speed. The practical application shows that the dynamic setting of the roll speed can ensure the stability of each rack speed and the tension between the racks in variable tandem mill during variable specification so as to ensure the strip thickness accuracy
