    • In a previous process, the influence of roll eccentricities on the output thickness of the rolled material in a roll stand is suppressed by simulating the output signal of an oscillator and supplying this value to a position or thickness control for the roll stand, where the frequency of the output signal is set according to the roll rotation speed. In the process according to the invention, the amplitude and phase of the output signal are set so that the exit thickness of the rolled material is measured with a measuring delay in relation to the thickness reduction in the roll gap. A difference signal is generated from the delayed roll screw-down signal and a measured thickness signal multiplied by the sum of one and the quotient of the rigidity of the rolled material and the roll stand. The output signal of the oscillator is corrected according to the difference between the output signal and the difference signal. The output signal is phase shifted by the amount of measurement delay for a forward slip.
    • 在之前的处理中,通过模拟振荡器的输出信号并将该值提供给辊架的位置或厚度控制来抑制辊偏心度对辊架中轧制材料的输出厚度的影响,其中频率 的输出信号根据滚动转速设定。 在根据本发明的方法中,输出信号的振幅和相位被设定为使得轧制材料的出口厚度以相对于辊间隙的厚度减小的测量延迟来测量。 从延迟的卷筒旋转信号和测量的厚度信号乘以轧制材料和轧辊机架的刚度的乘积乘以1的乘积产生差分信号。 振荡器的输出信号根据输出信号与差分信号的差异进行校正。 输出信号相移到前进滑差的测量延迟量。

    • A device is provided for regulating the thickness of rolling stock in a roller stand. The device includes a control device that controls the roller adjustment of the roller stand as a function of the deviation between a reference thickness value (h*) and an estimated value (h') for the thickness of the rolling stock exiting from the roller stand; a model simulating the rolling process in the roller stand, the model calculating the estimated value (h') on the basis of roller technology parameters and measured values; a thickness measurement device that measures the thickness of the rolling stock after its exit from the roller stand with a measurement delay (T.sub.L) providing a measured thickness value (h.sub.L); a delay device for delaying the estimated value (h') determined by the model by at least approximately the amount of the measurement delay (T.sub.L); a correction device generating a correction value (k) as a function of a deviation (.DELTA.h.sub.L) between the measured thickness value (h.sub.L) and a delayed estimated value (h'.sub.L), the correction value (k) correcting the estimated value (h') provided by the model; a controllable switching device enabling the generation of the correction value (k) to be stopped in time periods during which the thickness measurement device provides no measured thickness values (h.sub.L) or no usable measured thickness values; and a holding device making available during the time periods the correction value (k) last generated for correction of the estimated value (h') provided by the model prior to the generation of the correction value (k) being stopped.
