Rolling mill with method for online detection of at least one rolling parameter and device for online detection of at least one rolling parameter

摘要

The present invention relates to a rolling mill (10) comprising at least two rollers (12) on a rolling stand (11) for rolling a rolling stock (20) along a rolling line (13). It relates to a method for online detection of rolling parameters. The rolled stock (20), during rolling, passes or passes through at least one measuring device (31), which along the longitudinal extension (21) of the rolled stock (20): It acts on the varying rolling stock parameters of the rolling stock (20) and outputs a measurement signal (40). (i) the measurement signal (40) is transmitted in frequency space and the rolling parameter is detected from the measurement signal (40) transmitted in frequency space; It is characterized in that the frequency (41) is detected from the measurement signal (40) and the rolling parameter is detected on the basis of the predetermined frequency (41).
