Abstract
A method of rolling strip in a strip rolling train having at least two roll stands, each roll stand having horizontally adjustable upper and lower work rolls, wherein the work rolls act alone as a two-high stand or each work roll is supported directly or through an intermediate roll by a back-up roll, or in a reversing stand in which at least two passes are rolled, wherein the strip is subjected in the roll stands to a constitutional change, and wherein adjusting elements act on the strip for imparting a profile and surface evenness to the strip. The method includes presupposing in at least one strip area an intended surface unevenness shape over a width of the strip, determining an actually achieved surface unevenness shape in the strip area and comparing the actually achieved surface unevenness shape to the presupposed unevenness shape, computing a difference between the unevenness shapes, and operating the adjusting elements such that the difference is minimized.
