An adjusting cylinder for long, rapid lifting movements in rolling stands, includes vertical edging stands, wherein each cylinder has at least one piston, which acts through the bearing chocks of at least one work roll or of an interposed roll to adjust a work roll on both sides, wherein each adjusting cylinder has a piston that is equipped with two oppositely directed piston rods, and each piston is inserted in a recess in the cylinder base or cylinder cover, such that the base and cover have coaxially arranged bores through which the piston rods pass. The surface formed by one piston and the piston rod is smaller than the surface formed by another piston and the piston rod.

A roll stand for edgers in rolling mills. The roll stand is formed of several pieces, including two crossheads and four longitudinal bars as main components, as well as one respective common cruciform junction point for the crosshead and the longitudinal bars, which is located at the ends of the longitudinal bars. Pretensioned through bolts that act as a joint are used at least at the top ends of the longitudinal bars.

Rolling device with two work rolls supported in a rolling stand by a chock and with at least two additional rolls supported in the rolling stand by an additional chock. At least one of the work rolls and at least one of the additional rolls is adjustable for adjusting a desired roll gap relative to the other work roll or relative to the other additional roll. The work rolls have axial shifting devices for axial shifting and holding the work rolls into a desired axial position relative to the rolling stand. The work rolls are operatively connected with bending devices, by which a bending moment can act on the work rolls. The axial shifting devices are arranged and act between the rolling stand and the work roll locking mechanism. The bending devices are arranged or act between the work roll chock and the chock of the additional roll.

The invention relates to a rolling device (1) comprising two working rollers (2) which are respectively mounted in a roll stand (4) by means of working roller inserts (3). The working roller inserts (3) in the roll stand (4) can be locked and unlocked by means of at least one working roller locking device (5). At least two other rollers (6), especially two support rollers are respectively mounted in the roll stand by means of other inserts (7); the position of at least one of the working rollers (2) and at least one of the other rollers (6) in the roll stand (4) can be adjusted, especially in a vertical direction, in relation to the other working roller (2) or other roller (6) in order to adjust the desired rolling gap. The working rollers (2) are provided with means (8) for axial displacement, enabling the working rollers (2) to placed in a desired axial position in relation to the roll frame (4) and maintained in said position. The working rollers (2) are actively connected to blocking means (9) so that they can be impinged upon by a bending moment. In order to improve the adjustability of the rolling device to achieve a high rise, the axial displacement means (8) are arranged or operate between the roll stand (4) and the working roller locking device (5) and the bending means (9) are disposed or operate between the working roller insert (3) and the other working roller insert (7).

Disclosed is a roll stand for edgers in rolling mills. Said roll stand is embodied in several pieces, comprising two crossheads (1a, 1b) and four longitudinal bars (4a, 4b) as main components (1) as well as one respective common cruciform (7) junction point (3) for the crosshead (1a, 1b) and the longitudinal bars (4a, 4b), which is located at the ends (6) of the longitudinal bars. Pretensioned through bolts (5) that act as a joint are used at least at the top ends (6) of the longitudinal bars.

The invention relates to an adjusting roll for the rapid adjustment of rolls in rolling frames, among others vertical upset forging frames, comprising at least one respective piston, which acts on both sides of a working roll to adjust the latter, by means of assembled parts of at least one working roll or an interposed support roll. The inventive adjusting roll has been improved by the provision of a piston (KO), which is equipped with two piston rods (ST1, ST2) that point in opposite directions and the piston or pistons (KO) are inserted into a respective cavity in the roll base (ZB) or roll cover (ZD), said base and cover comprising coaxial bores for conducting the piston rods (ST1, ST2).
