摘要： A multistage rolling mill 100 includes support bearings 10a, 10b, 10c, 10d, 10e, 10f, 10g, and 10h arranged on the entry side and/or the exit side of work rolls 2a and 2b, and supporting the work rolls 2a and 2b on an work side and a drive side. The offset positions in a pass direction of the pair of work rolls 2a and 2b for rolling a strip 1 are changed by moving in and out the support bearings 10a, 10b, 10c, 10d, 10e, 10f, 10g, and 10h to the entry side or the exit side with respect to the pass direction. A multistage rolling mill capable of rolling a hard material efficiently and suitable for obtaining a strip of high product quality is thereby provided.

摘要： The invention relates to a method for calibrating a rolling stand (3), wherein in order to determine the relative pivot position of the roller set for setting a symmetrical roll gap and/or for determining the extension of the rolling stand (3) before the actual rolling process, the roller set is pressed against each other under a radial preset force and the resulting deformation of the rolling stand is preferably measured on the piston-cylinder unit (6, 7). The pivot position of the roller set and/or the frame module (M) determined based thereon are mathematically used during the subsequent rolling of a rolling stock between the working rollers (1, 2) for adjusting the roller set. In order to attain a higher accuracy during rolling, the invention provides for the working rollers (1, 2) to be axially adjustable relative to each other starting from a zero position that is not axially displaced, wherein the determination of the pivot position for setting a symmetrical roll gap and/or the determination of the frame module (M) are carried out in a relative displacement position of the working rollers (1, 2) that is not equal to the zero position (calibration position), wherein the determined pivot position and/or the value for the frame module (M) are stored and mathematically used for further calculating the pivot position and/or the adjustment of the roller set during rolling of the rolling stock.

摘要： A bending device for two working rolls of a rolling stand. Guide blocks provided in lateral roll housings for guiding two pressure-transmission bodies vertically adjustable with respect to each other and, on which the working rolls are supported via chocks. Bending cylinders are arranged in pairs between the pressure-transmission bodies at each end of the rolls. Each cylinder has a piston rod acting on one pressure-transmission body and a cylinder at the respective other pressure-transmission body. Each pressure-transmission body is supported on a respective guide block in a sliding manner. So that loads acting on the pressure-transmission bodies can be introduced into the guide block free of edge pressure, the pressure-transmission bodies are supported on the respective guide blocks in a sliding manner by self-adjusting wearing plates which include surfaces that enable both sliding and pivoting of the bodies with respect to the guide blocks.

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.
