Roll stand for producing plane roll strips having a desired strip profile superelevation

Rolling mill for producing plane rolled strips (6) having a desired strip profile superelevation, with work rolls (1, 2) supported on at least one backup roll (3, 4), such that the work rolls (1, 2) have different diameters, and the thicker work roll (2) is connected with a drive (5), while the thinner work roll (1) follows as an “idle roll,” wherein

• the backup rolls (3, 4) and the work rolls (1, 2) are arranged in the rolling stand (10, 11) in such a way that they can be axially displaced,
• at least one of the work rolls (1, 2) can be adjusted in the discharge direction (7) of the rolled strip (6), and
• the backup rolls (3, 4) and the work rolls (1, 2) are provided with a curved contour over essentially the entire length of the body (CVC grind (continuously variable crown), which is determined by a polynomial of at least second order), such that these contours are staggered by 180° relative to each other and are each configured so that the two body contours of the work rolls (1, 2) complement each other to form a symmetrical contour of the roll gap, wherein the backup rolls are lengthened relative to the work rolls, and wherein different work roll bending forces can be adjusted for each of the work rolls (1, 2) and for each of their sides as a function of their sliding position.
