An adjusting cylinder quick-action adjustment for a long, rapid stroke movement in an edging stand which includes an edger upright, adjustment system, balancing system and edging roll sets, comprises a piston which acts via edging roll chocks of at least one edging roll for adjustment against the rolling stock. The adjustment of the edging roll can be actuated on each side hydraulically by a fluid. The adjusting cylinder quick-action adjustment is mounted in the edger upright and exerts the force required for the edging process. The adjusting cylinder quick-action adjustment includes on each side of the edging upright at least one double cylinder which has two cylinders coupled to one another and is separately controllable and configured for rapid adjustment and for control adjustment of the edging roll.

Quick-action adjustment for adjusting cylinder in edging stands

The invention relates to a devicefor positioning an edging rollof an edging stand, comprising an edging frameto which at least one balancing cylinderis attached, a balancing crossbeamwith a drive sidepositioned opposite of the edging frame, and a working sidepositioned opposite of the drive side, wherein a bearing devicefor the edging rollcan be attached, in particular in an interlocking manner, to the balancing crossbeamon the working sidethereof and at least one linkageis provided on the drive sidethereof, by which linkage the balancing cylinderis in an operative connection with the balancing crossbeam, and at least one positioning cylinderattached to the edging framecan be brought into an operative connection with the bearing device () in the direction of a rolled material in order to position the edging rollagainst the rolled material, wherein the compressive force generated by the positioning cylinderacts on the bearing devicealong an operational axis, which either intersects with the at least one linkageby which the balancing cylinderis operatively connected with the balancing crossbeamor runs directly alongside this linkage

Device for adjusting an edging roll of an edging stand

The invention relates to a compression rolling mill for compressing a metal strand sideways, having a pair of mutually engaging rollers (), arranged perpendicular to the center axes, connected to a rotary drive () by means of articulated shafts (), characterized in that the two rollers () are connected to the rotary drive () by means of a gearbox () adjustable together with the rollers () and by means of articulated shafts () each connected to one of the two gearboxes (), wherein the articulated shafts () are inclined at an acute angle to the horizontal.

An adjusting cylinder for long, rapid lifting movements in rolling stands, including vertical edging stands, wherein each adjusting 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 the piston and the piston rod is smaller than the surface formed by the piston and the piston rod.

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.

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 (ST, ST) 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 (ST, ST).

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.

Multi-part roll stand for edgers in rolling mills

In a rolling mill which consists of at least one horizontal stand () and at least one vertical stand (), which are connected with each other, between both stands (), connection elements () are releasably arranged, wherein the connection elements () consist of a right flange (), a left flange (), and a web () arranged therebetween.

Rolling mill consisting of horizontal stands and vertical stands

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.

Rolling device

A guide device on a vertical roll rolling mill frame (WG) which has vertical guide plates (FP) for the rolled product on both sides of the vertical roll pair (VW) above the rollers (RR) of the roller conveyor for feeding the rolled productand removing the rolled product from the roll and on a carrier (TR) for each vertical guide plate (FP), shiftable transversely to the rolling direction, adjustable and lockable. The carrier (TR) of each guide plate (FP) is connected on its back side with the linear positioning member of a mechanically or hydraulically driven shifting device which is fixed on the bearing body (LK) of the vertical roll. The carrier (TR) is cantilevered slidably above the roller conveyer and parallel to its roller axed in a cantilevered kulisse (FK) which is fixedly connected with the rolling mill frame.
