Abstract
Procedure for detecting and analyzing in operation the fluctuations of the rolling force caused by eccentricities of the cylinders in a rolling stand, equipped with a device for regulating the thickness of a rolling product leaving the rolling stand, depending on the rolling force determined by means of manometric capsules, characterized in that the amplitudes of the rolling force fluctuations caused by the roundness of the cylinders are detected by several limit value warnings adjusted to different reaction values, and a variable resistance, arranged in the feedback channel of the input amplifier of an analog-digital converter connected to the manometric capsules, it is varied depending on the magnitude of the amplitudes of the fluctuations of rolling force detected by the limit value warnings, in such a way that for regulation of the thickness, only the variations in lamination force, caused by the lamination product, which exceed the respective amplitudes of the lamination force fluctuations, are free.
