Abstract

The method for regulating the exit thickness of a rolled strip after at least one roll stand, with the deviation from the strip target thickness used as a controller of an adjustment variable, is characterized by the fact that the coefficient of friction between the roll stand and the strip is used as an adjustment variable.
