Estimating the term…
In a method for the online determination of at least one rolling parameter when rolling a rolling material rolled along a rolling line in a rolling mill including at least two rolls on a roll stand, the rolling material is guided past or through at least one measuring device during the rolling, which interacts with a rolling material variable of the rolling material, the rolling material variable being changeable along the length of the rolling material, and outputs a measurement signal, wherein: (i) the measurement signal is transferred into the frequency space, and the rolling parameter is determined from the measurement signal transferred into the frequency space, and/or (ii) a frequency inherent in the change of the rolling material variable is determined from the measurement signal, and the rolling parameter is determined on the basis of the determined frequency.

A method for the online detection of at least one rolling parameter when rolling a rolled material (20) rolled along a rolling line (13) in a rolling mill (10) comprising at least two rollers (12) on a rolling stand (11) where the rolled material (20) is a rod or a pipe and where rolled material (20) is passed by or passed through at least one measurement device (31) during rolling, which interacts with a varying rolled material parameter of the rolled material (20) along the longitudinal extension (21) of the rolled material (20) and outputs a measurement signal (40), wherein the measurement device (31) measures perpendicular to the rolling line (13) across the circumference of the rolled material (20) in an integrating and/or averaging manner and
A rolling mill (10) comprising at least two rollers (12) arranged on a rolling stand (11) for rolling rolled material (20) along a rolling line (13) and a device (30) for online detection of at least one rolling parameter, wherein the rolled material (20) is a rod or a pipe and wherein the detection device (30) comprises at least one measurement device (31) which is arranged on the rolling line (13) and that can interact with a varying rolled material parameter of the rolled material (20) along the longitudinal extension (21) of the rolled material and can output a measurement signal (40), wherein the measurement device (31) measures perpendicular to the rolling line (13) across the circumference of the rolled material (20) in an integrating and/or averaging manner and the detection device (30) comprises means (32) for frequency analysis.
The rolling mill (10) according to claim 8, wherein the rolled material (20) is metallic.
