    摘要： 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.

    摘要： 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.

    摘要： A device to bend the rolls (10) in a rolling stand, wherein each roll to be bent (11) is rotatably mounted in two corresponding chocks (12) each associated to two series of two double-effect actuators (13), for a total of four actuators (13) for each chock. Each actuator (13) is disposed on opposite sides of the corresponding chock (12) with respect to the axis of rotation (Y) of the roll (11) to be bent.
