Summary:A rolling mill stand has two working rolls forming a roll gap in which a rolled product transported in a conveying direction can be formed. The positioning of at least one working roll is variable in a plane perpendicular to the conveying direction. The rolling mill is used in a method which comprises: conveying the rolled product through the roll gap in the conveying direction and at the same time opening or closing the rolling mill stand by correspondingly increasing or decreasing the roll gap; during opening or closing of the roll stand, detecting a position of the rolled product in front of and/or behind the roll gap in the direction transverse to the conveying direction; and changing the positioning of the corresponding working roll depending on the detected position, so that the rolled product is stabilized at a target position during opening or closing of the roll stand.
