    Abstract: The rolling mill stand comprises a bending device and a shifting device for the rolling rolls. The housing supports the upper backing and work rolls, and the lower backing and work roll and comprises the lower bending block, the upper bending block, the chock of the upper work roll, the chock of the lower work roll, the axial shifting device of the upper work roll, the axial shifting device of the lower work roll. The chock of the lower work roll is coupled with the lower bending block to transmit a bending load on the lower work roll. The upper bending block transmits a bending load on the upper work roll by means of the action of actuators. The bending block comprises a slide with a T-section which slides in the guide and a chock of the upper backing roll, whereby the upper bending block, instead of being a single piece, is formed by two different and separate structural components.

    Abstract: The invention relates to a roll bending device for the control of profile and flatness in the rolling of metal plates or strips. In particular the invention relates to the well known principle of roll bending by using hydraulic cylinders to modify the load distribution between rolls of a rolling mill stand and a rolled stock e.g. a metal plate or a strip in order to control the profile and flatness of the metal plate or strip. A special design to allow safe roll bending even at large roll gauges is presented. The new design allows safe operation even at large roll gauges and high side loads.

    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.

    Abstract: The object is to strictly eliminate the difference in offset of work rolls at the upper and lower and left and right of the rolling mill occurring in the kiss roll state before rolling or during rolling and eliminate the problem of warping of the flat products or meander or camber due to the thrust force acting between the work rolls and backup rolls.For this, there are provided a rolling mill for flat products having a pair of upper and lower work rolls driven by electric motors, a pair of upper and lower backup rolls, and devices for applying substantially horizontal direction external forces to barrels or shafts of the work rolls at positions of at least one location each at the work side and drive side, for the respective upper and lower work rolls, from the entrance side or exit side of the rolling mill, the external forces being supported through work roll chocks by project blocks of the rolling mill housing or work roll chock support members connected to backup roll chocks, and the value of the rolling direction offset of the work roll axial center position and backup roll axial center position divided by the sum of the work roll radius and backup roll radius being 0.0025 or less for both the upper and lower rolls, and a rolling method for flat products using the same.
