Abstract

A method for rolling plate or strip in a rolling stand with work rolls supported on backup rolls or on intermediate rolls with backup rolls, wherein the adjustment of the roll gap profile is carried out by axial shifting of pairs of rolls provided with curved contours. The adjustment of the roll gap profile is carried out by at least two pairs of rolls, which have differently curved contours and can be axially shifted independently of each other and whose different contours are calculated by splitting the resultant desired roll gap profiles that describe the roll gap profile into at least two different desired roll gap profiles and are transferred to the pairs of rolls.
