Abstract:
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.
