Abstract (en)

[origin: WO2005035156A1] The invention relates to a method and a control device for operating a mill train for metal strip (1), which comprises at least one roll stand (3), the intrinsic flatness (ip) of the metal strip (1) being determined at the discharge point of the mill train. In order to ensure in a reliable and sufficiently accurate manner that a required visible flatness (vp) of the rolled metal strip (1) is kept within predefined limits, the bulging behavior of the metal strip (1) is measured at the discharge point of the mill train and is translated into the intrinsic flatness (ip) of the metal strip (1) by means of a bulging model (12). The visible flatness (vp) can thus be better regulated online along the entire mill train by using the bulging model (12).
