Abstract

Method for influencing relevant quality parameters of a rolling strip, particularly the profile or flatness of the rolling strip, in a roll stand with rolls, by adjusting the crownings of the rolls, i.e., the surface geometry of the rolls in the longitudinal direction of the rolls, wherein the crowning of the rolls is adjusted by an adjustable cooling of the rolls or of their surfaces in longitudinal direction of the rolls. The cooling of the rolls is adjusted by a controller (1) as a function of the actual value (pactual) of the crowning and a predetermined setpoint value (psetpoint) of the crowning.
