摘要： The invention relates to a roll stand comprising a crown-variable-control (CVC) roll pair, preferably a CVC working roll pair and a back-up roll pair, which comprise a contact area (bcont) in which a horizontally active torque (M) acts that leads to a twisting of the rolls and thus to axial forces in the roll bearings. In order to keep the axial forces in the roll bearings as small as possible, the torque (M) is minimized by an appropriate CVC grinding.

摘要： When rolling steel sheet and other rolled stock, rattling occurs in certain operating states. This results in reduced quality of the rolled stock and rejects as well as damage to the rolling mill. No improvement was achieved by placing brakes on the cylinders. Electronic monitoring is not a satisfying solution. Given that rattling is a self-starting oscillation, resistance sensors are coupled to the cylinders and/or the rolled stock in order to stabilize the self-starting oscillation modes, modes with negative damping, by means of additional damping. In the example illustrated in FIG. 4, cylinder-shaped, rotating dampers are coupled to the working cylinders. Concentric or disc-shaped layers made of steel and plastic such as those found in layered oscillation absorbers are most effective and adaptable. The arrangement of the working cylinder and the damper illustrated in FIG. 4 makes it possible to suppress vertical (nullx1 direction) oscillations and the self-starting rattling oscillations in x2 and null5 direction responsible for the thickness and form waves caused by rattling in the rolled stock.

摘要： A roller assembly for processing a substantially planar workpiece includes a first pinch rod and a second pinch rod mounted in opposition to the first pinch rod, the workpiece passing between the first pinch rod and the second pinch rod during operation. A radius rod is also mounted adjacent to the first pinch rod and the second pinch rod, the radius rod being selectively displaceable with respect to the first and second pinch rods to contact the workpiece after the workpiece has passed between the first and second pinch rods, the radius rod conferring a predetermined radius of curvature to the workpiece. The roller assembly further includes a roller mounted onto one of said first pinch rod, the second pinch rod or the radius rod, the roller being selectively positionable along one of the first pinch rod, the second pinch rod and the radius rod.
