Abstract: A roll device for rolling metal strips comprises a first and a second work roll which define a roll gap therebetween, and a first and a second backup roll. In a common rolling mill stand, at least one work roll is mounted in work roll chocks and the backup rolls are mounted in backup roll chocks. The work roll chocks are designed such that the first and/or the second work roll can each be replaced by a roll arrangement having a work roll with a smaller diameter and at least one additional roll. The work roll with the smaller diameter is supported via the additional roll. The additional roll is mounted in additional roll chocks and the work roll with the smaller diameter is situated in work roll bearings of the additional roll chocks.

Abstract: The invention relates to an apparatus (1) for the applying of and removal by suction of operating fluids onto rolling stock (2) and off rolling stock (2) in the inlet (4) of cold rolling systems (6) and comprises at least one spray device (7) arranged above or below a rolling stock transport line (8), wherein at least one operating fluid can be placed by the spray device (7) onto a surface of the rolling stock (2) or onto a surface of a working roll (9) which makes contact with the rolling stock (2), and to at least one suction removal device (10) which can be arranged above or below the rolling stock transport line (8) and on the same side of the rolling stock transport line (8) as the spray device (7), wherein the suction removal device (10) acts in the vicinity of the surface of the rolling stock (2) or of the working roll (9). The spray device (7) and the suction removal device (10) are attached onto a common component frame (12) and therefore form a compact unit (14.1; 14.2).

Abstract: A guiding device for the chocks of work rolls of a rolling stand comprising guides arranged fixedly or horizontally movably on the inner sides of the windows of the rolling stand, wherein the upper and lower bending blocks of each side are respectively assigned two guides arranged parallel to each other. Each bending block is assigned one of the guides, while it has a recess for the parallel running guide that extends around said guide, wherein the upper bending block is guided on one of the parallel guides and the lower bending block is guided on the other guide.

Abstract: In a device for mounting and functional verification of roll fittings (4) in rolling mill stands (1), at least a partial number of the roll fittings (4) forms a respective module (5), and the modules (5) are arranged, for pre-assembly with functional verification, on a mounting plate outside of the roll stand (1), with the modules being adjusted and/or verified, and at least one adjusted and/or verified module (5) is operatively arranged between two rolling mill stands (1), primarily, in the stand gap (9) and is arranged on a base frame (8) at constructively fixable support points (10).

Abstract: The invention pertains to a roll arrangement (1, 101, 201), especially a roll arrangement of the work rolls (2, 3, 102, 103, 202, 203) of a rolling stand, which can be shifted in the axial direction by adjusting means (4, 104, 204), where the adjusting means (4, 104, 204) comprise at least one hydraulic cylinder (5, 6, 105, 106, 205), which controls the axial shiftability of the rolls, where the hydraulic cylinder is arranged in a frame, which is stationary or adjustable.

Abstract: The invention relates to a roller device (1) comprising a stand with support posts (2, 12, 33), wherein at least one roller (3, 13) of the roller stand is arranged in the space between the support posts and at least one adjuster device (5, 10, 30) is provided for adjusting the rollers (3), wherein the at least one adjuster device (5, 10, 30) is arranged between the rollers (3, 13) and the support posts (2, 2a, 2b, 2c, 2d, 12, 33) and comprises a pressure medium adjuster body (14, 23, 34).
