Abstract

PURPOSE:To control the dissimilar speed rates of arbitrary one or more rolling mills out of rolling mill trains with a speed control system and an independent system by correcting roll peripheral speeds on high speed side, low speed side, etc. so as to satisfy specific equations in accordance with roll peripheral speeds and roll gaps. CONSTITUTION:In the case of performing continuous rolling with rolling mill trains disposed with plural units in tandem, a high speed side roll peripheral speed Vhj, a low speed side roll peripheral speed Vlj, roll gaps and coeffts. of plasticity are corrected in such a way as to satisfy the equations in accordance with the roll peripheral speed Voj, roll gap Soj of the stand j outputted as command values from a system of performing tension control, plate thickness control and looper height control, whereby reference AGC load is changed to Poj-BjXj and the dissimilar peripheral speed rolling of a dissimilar speed rate Xj is accomplished in the arbitrary stand j. Here, Kj: the mill ridigity of the stand j, alphaj: the change rate of the high speed side advance rate at the dissimilar speed rate, betaj: the change rate of the rolling load of the stand j by the dissimilar speed rate, Xj: a dissimilar speed rate, Xj=VHj/Vlj-1, Poj: the reference AGC load when Xj=0, Moj: the coefft. of plasticity when Xj=0.
