  • the present invention is further based on a control device for a finishing train, wherein the control device is programmed with such a computer program, so that the control device operates the finishing train according to such a method.
  • a hot rolling mill for rolling metal strip usually consists of a roughing train, a finishing train and a coiler.

  • - usually at least in hot strip mills for rolling steel strip - is still a cooling line available.
  • the cooling section if it is present, downstream of the finishing train and upstream of the reel device.
  • the width of the metal strip is influenced both in the roughing mill and in the finishing mill as well as on the way to the coiler. In some cases, this influence is active.
  • width influences in the nip such as a relative band profile change, a roll bending, a pressed length and the inlet side and the outlet side train are taken into account.
  • width influences in the area between two rolling stands such as the temperature, the tension prevailing in the metal strip, the yield strength, the strip temperature and the duration are taken into account.
  • a simplified width model is derived based on a finite element based width model.
  • the simplified width model is supplemented with a neural network. It models the width of the finishing line as a function of the entry-side tension in the metal strip, the current width, the thickness reduction, the pressed length and the deformation resistance.

  • the actual widths and actual temperatures assigned to the sections are identical to the detected actual widths and actual temperatures.
  • at least the detected actual widths, preferably also the detected actual temperatures, are filtered, in particular low-pass filtered.
  • the filtering can in particular be such that no phase offset is induced by the filtering in the filtered variable (actual width or actual temperature) compared to the unfiltered variable. So filters should be done in zero phase filters. For this purpose, it is possible, for example, to provide a correspondingly symmetrical filter. Alternatively, it is possible for the detected actual widths to be subjected to a first filtering and thus provisionally filtered actual widths to be determined, and then the preliminarily filtered actual widths to be subjected to a second filtering and thus the filtered actual widths to be determined. Alternatively, the detected actual widths can be subjected to both the first filtering and the second filtering in parallel, and the mean value of the two filters can be used as the filtered actual width.
  • the two filters can be phase-locked. It is only necessary that the two filters are inversely phase-locked relative to one another, so that the phase offset caused by one filtering is compensated or compensated by the other filtering.

Alternatively, it is possible to determine the respective speed by detecting the circumferential speed of rolls of an upstream roll stand, based on the location for which the speed of the metal strip is to be detected, and determining the speed of the metal strip taking into account the lead , In an analogous manner, conversely, it is possible to determine the respective speed by detecting the peripheral speed of rollers of a downstream roll stand and determining the speed of the metal strip taking into account the lag.
