Problems solved by technology

The two mentioned solutions have the disadvantage that it is generally only possible to increase the chatter limit speed, that is to say the rolling speed at which the stability limit for self-excited third-octave chatter is reached, by a relatively small amount. , such as 50m / min to 200m / min
The maximum possible device speed cannot be achieved in most cases with these solutions

Embodiment Construction

[0043] figure 1 A schematic perspective view of an embodiment of a rolling installation 1 for rolling, in particular cold rolling, metal objects according to the invention is shown. The rolling installation 1 comprises a rolling stand 2 and a system 3 for actively damping vibrations in the rolling stand 2 .

[0044] The rolling mill stand 2 comprises an upper work roll 4 and a lower work roll 5 cooperating therewith, forming a roll gap 6 between the upper work roll and the lower work roll. The work rolls 4 and 5 are respectively guided at the end sides via a bearing unit 7 on each column 8 of the rolling stand 2 . In addition, the rolling mill stand 2 includes an upper back-up roll 9 supporting the upper work roll 4 and a lower back-up roll 10 supporting the lower work roll 5 . The back-up rolls 9 and 10 are respectively guided at the end sides via a bearing unit 11 on each column 8 of the rolling stand 2 . In addition, the rolling stand 2 also includes two adjusting units ...

Abstract

The invention relates to a roll stand (2) for rolling, in particular cold-rolling metal products, comprising at least one actuator (16) which can be actuated for actively damping vibrations in the roll stand (2), and at least one support roll (10), which is non-adjustable or can be adjusted exclusively via an adjuster for pass line adjustment (13) of the roll stand (2), for supporting a working roll (5) and / or intermediate roll of the roll stand (2), wherein the support roll (10) is guided at the ends via a respective bearing unit (11) on a rack (8) of the roll stand (2). According to the invention, in order to permit an optimal active damping of vibrations in a roll stand (2) of this type with low constructive effort, the support roll (10) is supported on the actuator (16) via at least one bearing unit (11), and the actuator (16) is supported on a section (17) of the rack (8) either directly or indirectly via at least one component (14) of the adjuster (13).

Description

technical field [0001] The invention relates to a rolling stand for rolling, preferably cold-rolling, metal products, said rolling stand having at least one actuator which can be actuated for actively damping vibrations in the rolling stand and which The rolling stand has at least one roll set which is not adjustable or can only be adjusted by means of a readjustment device for the pass line adjustment of the rolling stand, which roll set is used to support the intermediate rolls and / or of the rolling stand Work rolls, wherein all rolls are guided at the end sides by a bearing unit in each case on the columns of the rolling stand. [0002] The invention furthermore relates to a rolling installation for rolling, preferably cold rolling, metal objects, having at least one rolling stand and at least one system for actively damping vibrations in the rolling stand. [0003] Furthermore, the invention relates to a method for actively damping vibrations in a rolling stand for rollin...
