    摘要： The invention relates to a strip (4) comprising a strip head (10) and a strip leg (11). It is rolled, beginning at the strip head (10), in a roll stand (1) of a rolling device between an upper and a lower roller arrangement (2, 3) of the roll stand (1). It is monitored whether the strip foot (11) reaches a switching point (12) located, viewed in the rolling direction (x), in front of the roll stand (1). From the time the strip leg (11) reaches the switching point (12), the roller arrangements (2, 3) are subjected to a bending force (F) expanding the roller arrangements (2, 3) by means of an adjusting device (5), the force being at least as high as a minimal force. The minimal force is at least as high as a balancing force of the upper roller arrangement (2). The minimal force is determined as a function of the parameters of the strip (4) and/or the operating parameters of the rolling device.

    摘要： The invention relates to a roll stand, especially a duo or quarto roll stand, comprising bending and balancing devices (7) for axially displaceable rollers (4, 5). A fixed guide block (6) is secured on both sides in the window (1) of each roller stand (2) on the same level as the roller inserts (3). The force of the bending cylinders (8) is transmitted to the roller inserts (3) which are guided in the direction of the axis in a vertically displaceable manner. The length of the bending cylinders (8) on the upper and lower piston end is respectively greater than the width thereof and the longitudinal axis of the bending cylinders extends in the direction of axial displacement of the rollers (4,5).

    摘要： The present invention relates to a rolling mill, a gap-removing apparatus for roll bearing boxes, a rolling method, a modifying method for a rolling mill, and hot finish tandem rolling equipment, and is characterized in that there are provided roll bearing boxes for rotatably supporting work rolls in a housing, a first pushing device for applying a vertical balancing force or bender force to the work rolls through the roll bearing boxes, and a second pushing device for applying a pushing force in a direction orthogonal to the work roll axis in a horizontal plane to the roll bearing boxes, and the first pushing device and the second pushing device are disposed to be offset from each other in the work roll axis direction. Alternatively, the invention is characterized in that the second pushing device is disposed between a plurality of the first pushing device in the work roll axis direction. Gaps at the roll bearing boxes in the rolling mill can be removed without enlarging the equipment in size.

    摘要： Vibration damping apparatus (40) includes a body in the form of backup roll balance piston (42) positionable for sliding movement in an enclosure in the form of cavity (44) in the lower backup roll chock (30) of the mill stack (10). The body of the piston is a casing which performs the role of a conventional postion. A damping means is integral with the piston (42) for providing vibration damping of opposing backup roll chocks (24, 30). The damping means is a specially designed absorption system to provide tuned stiffness and damping elements which act in parallel and are located in compartment (46) at an uppermost end or cap of the piston (42). A second vibration absorbent compartment portion (56) of the piston (42) also includes vibration absorbing components. Portion (56) is an integral cap located at the end of the piston (42) in contact with the fluid (52).
