Abstract

Method and apparatus for presetting process variables in at least one actuating element of a rolling train for rolling metal strips, in which guarantee values are predefined. The guarantee values specified, which cover the intended stipulations and the associated tolerance bands for the quality features of the metal strip, are, for example, strip flatness and/or strip contour and/or strip profile. The tolerance bands of the intended stipulations over a predefinable number of metal strips are taken into account in such a way that an optimum set point calculation of at least one process variable is carried out over the predefined number of metal strips.
