    摘要： The invention relates to a method for rolling strips in the roll stand of a rolling mill, wherein said roll stand consists of two axially displaceable working rollers which are provided with a CVC-grinding or a similar contour and whose curved profile is expressed in a third or higher-order polynom and, simultaneously with simple handling of working rollers with large possibilities of adjusting the profile and flatness, the aim of said invention is to homogenize the working rollers wear. For this purpose, the increased cyclic shifting of the working rollers is induced or forced by a cyclic variation of the setting values of the curve of the working cylinders from one strip to another in a predetermined part of the adjustment range thereof, wherein the combined the action of the two adjustment systems (the curve of the working cylinders and the shift thereof) enables the parabolic effects of said two adjustment systems to supplement each other with a high approximation, thereby ensuring the flatness and, in addition, optimally homogenizing the working roller wear.

    摘要： The invention relates to a method for providing at least one work roll (1, 2) for rolling strip-shaped rolling stock (3), wherein the work roll (1, 2) is provided to interact with a second roll (4, 5), particularly with an intermediate or backup roller and be supported by said second roll, wherein the second roll (4, 5) has a background area (6) in the axial end regions thereof. In order to improve the quality of a rolled strip, the method according to the invention provides the following steps: a) calculating the roll nip profile resulting between two interacting work rolls (1, 2), wherein a defined width of the rolling stock (3) is assumed, which extends at least partially into the region of the background area (6) of the second roll (4, 5); b) defining a desired rolling stock contour that is to be created by the rolling process when passing the work rolls (1, 2); c) calculating a compensation cut for the work roll (1, 2) by subtracting the defined rolling stock contour according to step b) from the roll nip profile according to step a) and multiplying the calculated difference with a damping factor (K); d) at least partially applying the compensation cut calculated according to step c) to at least one work roll (1, 2).
