Abstract (en)
[origin: WO2011038964A1] The invention relates to a design for the model-based determination of actuator nominal values for the symmetric and asymmetric actuators of the roll stands of a hot wide strip mill, by which means the application of the actuator nominal values enables the adjustment of a desired target contour of the roll gaps of the stands. In a first method step, a nominal speed distribution at the outlet of each stand is defined. In a second step, strip thickness contours at the outlets of the stands are determined by means of strip flatness models. In a third step, roll separating force distributions to be applied for each stand are distributed by means of material flow models. In a fourth step, the target contour for the symmetric actuators and a target contour for the asymmetric actuators is determined. In a fifth step, the nominal values for the symmetric and asymmetric actuators are calculated for each stand, from the determined target contours, by means of optimisation methods.
