Abstract: Device (10) and method for winding/unwinding rolled products (20). The device (10) is interposed between a rolling unit located upstream (102) and a rolling unit located downstream (105). The device (10) comprises a heating furnace (11) and a support structure (16) disposed outside the heating furnace (11). On the support structure (16), substantially in a diametrically opposite position, two winding/unwinding drums (18a, 18b) are assembled, positioned inside the furnace (11). The support structure (16) is selectively rotating to alternatively dispose a first of the two drums (18a or 18b) in its winding position or in its unwinding position of a reel (29). A second of the two drums (18b or 18a) consequently assuming the opposite unwinding or winding position.

Abstract: A rolling stand with a bending and shifting device for rolling rolls with two lower blocks fixed to the housing and carrying a lower chock, two upper blocks connected to an upper chock, a shifting device for the upper roll connected to the upper chock via a sliding coupling, a shifting device for the lower working roll connected to the lower chock via a sliding coupling. The lower chock is coupled to the blocks via a sliding coupling which allows the chock to be moved in a vertical direction to generate a bending of the lower roll via actuators. The two upper blocks are vertically coupled with the housing to allow the upper roll to be bent. The shifting movement of the upper roll is achieved via a sliding coupling between the upper chock and the two upper blocks, and may be carried out under load when rolling operations occur.

Abstract: A rolling stand with a bending and shifting device for rolling rolls with two lower blocks (12, 13) integrally fixed to the housing (2) and carrying a lower chock (17), two upper blocks (14, 15) connected to an upper chock (16), a shifting device (30) for the upper roll (10) connected to the upper chock by means of a sliding coupling, a shifting device (31) for the lower working roll (11) connected to the lower chock by means of a sliding coupling. The lower chock is coupled to the blocks (12, 13) by means of a sliding coupling which allows the chock (17) to be moved in a vertical direction to generate a bending of the lower roll (10) by means of actuators (20, 21). The two upper blocks (14, 15) are vertically coupled with the housing (2) to allow the upper roll (10) to be bent. The shifting movement of the upper roll (10) is achieved by means of a sliding coupling between the upper chock and the two upper blocks, and may be carried out under load while the rolling operation occurs.

Abstract: An apparatus for the winding of striplike material, in particular steel strip, in each case on one of two spreadable winding mandrels which are arranged, overhung, horizontally and parallel to one another and which, driven in rotation independently of one another, are mounted, in a carrying structure rotatable about a common horizontal central axis, on a vertical carrying wall in the form of a circular disk. The carrying wall in the form of a circular disk is arranged coaxially at the end of a central carrying shaft mounted, at its end opposite the carrying wall, in a rotary bearing.

Abstract: A device for winding strip-type material, especially steel strip, alternately on each of two expandable coiler drums arranged horizontally and parallel to one another, which are mounted in free-floating fashion in a carrying frame arranged in rotary-drivable fashion around a shared horizontal central axis and are themselves rotary-drivable independently of one another. The rotary drives for the coiler drums together with the carrying frame are attached to the frame in rotatable fashion. The drum-type carrying frame consists of two vertical circular-disk-type carrying walls which are separated from and parallel to one another. Longitudinal traverses connect the carrying walls together. On the longitudinal traverses are mounted the coiler drums, which penetrate one carrying wall, and their expanding drives. Flanged onto the outside of the other carrying wall are the simultaneously drivable rotary drives, which are connected to the coiler drums through universal joint shafts in geared fashion.

Abstract: A drum-type shear for cutting high-speed strip, especially hot strip, includes a blade that is movable radially into and out of a rotating blade drum from which it is extendable into a strip-cutting position at a desired cutting time. In order to provide reliable and accurate cross-cutting of even broad and thick strips using nevertheless simple structural means, a linearly translatable push-pull rod that extends axially in the blade drum has wedge surfaces that abut with corresponding wedge surfaces of the blade or blade holder for extending and retracting the cutting blade. The push-pull rod rotates with the blade drum and is connected to a stationary linear drive via a thrust bearing for transmitting axial rod-translating forces to the push-pull rod as the rod rotates with the drum.

Abstract: The invention refers to an expandable mandrel reel to coil strip-like rolling material, particularly hot strip, with an inner mandrel shaft, as well as several expanding segments affixed to the latter. The segments are spread by activating a tie rod, and are supported on several wedge faces on the mandrel shaft and rising in the longitudinal direction of the shaft. Means are provided for keeping the expanding segments in place against centrifugal force.
