Abstract: A roller for a rolling mill with a casing, a left half pivot, and a right half pivot. The half pivots in the region surrounded by the casing are constructed as a truncated cone and form a left surface on the left half pivot and a right surface on the right half pivot. The left half pivot and the right half pivot have boreholes and corresponding grooves formed on the surfaces. The half pivots are inserted in the casing and are braced with one another by at least one tie rod. An hydraulic oil in boreholes and grooves is passed into or onto the left half pivot and the right half pivot. The hydraulic oil exerts a pressure on the casing to expand the casing. With the casing expanded, the stop surfaces and the face surfaces of the casing are pressed onto one another by the tie rod.

Abstract: Disclosed is a support roll for a rolling mill, such as a plate rolling mill, flat rolling mill, or similar, comprising a jacket and a roll shaft which is embodied in several parts. The invention also relates to a method for producing a support roll.

Abstract: The invention relates to a cooling device (100) for cooling a metal strip (200) after a forming in a cold rolling stand (200) having at least one nozzle (112) for spraying a cooling medium (400) onto the surface of the metal strip (200). In order to make such known cooling device more effective and efficient, it is proposed according to the invention to provide a plate (500), which in an operating position is arranged parallel to the surface of the metal strip (200) in the run-out of the cold rolling stand (300) and to arrange the nozzle in the operation position in such a manner that the cooling medium is sprayed at an acute spray angle ? into a cavity between the surface of the metal strip and the opposing plate, with a spray direction (R) opposite to the running direction (L) of the metal strip.

Abstract: Disclosed is a support roll (1) for a rolling mill, such as a plate rolling mill, flat rolling mill, or similar, comprising a jacket (2) and a roll shaft (3) which is embodied in several parts. The invention also relates to a method for producing a support roll (1).

Abstract: 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.

Abstract: The invention relates to a device for clamping a blade (10) of a pair of shears, used in the transversal cutting of strips, in particular a pair of shears for transversally cutting rolled strips and/or cropping shears. Said device comprises a piston (3), a piston rod (4), a compression spring (5), a cover (6), a fixing device (7) and a clamping bar (8), a second piston (16) being positioned at a distance from the first piston (3).

Abstract: In a rolling mill which consists of at least one horizontal stand (1) and at least one vertical stand (2), which are connected with each other, between both stands (1, 2), connection elements (7) are releasably arranged, wherein the connection elements (7) consist of a right flange (14), a left flange (12), and a web (13) arranged therebetween.

Abstract: A method of operating a flying shear for cutting a rolled strip, which includes at least one drum provided with a blade, includes synchronizing a peripheral speed of the blade with a feed rate of the rolled strip, and cutting the rolled strip by effecting a partial penetration of the blade in the rolled strip to produce a weakened location of the rolled strip, and by tearing the rolled strip at the weakened location by a tensile force.

Abstract: 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.

Abstract: A high-speed shear with a knife, particularly a chisel-type knife with a knife edge, arranged on at least one of two oppositely arranged drums, wherein the knife can be accelerated to the feeding speed of the rolled strip and the drums can be adjusted relative to each other for carrying out a cut. At least one drive unit provided for the drums serves to accelerate the drums to the speed of the rolled strip to be cut and at least one of the drums may be provided with a separately controllable adjusting device. The chisel-type knife of the knife drum is mounted so as to protrude from the cutting circle towards the anvil or the surface portion of the second drum acting as an anvil and to mount the chisel-type knife of the knife drum so as to be resiliently supported against a predetermined restoring force.

Abstract: A roll stand with work rolls supported by a back-up roll either directly or through an intermediate roll, particularly work rolls which are axially displaceable in opposite directions, wherein at least one of the rolls of the roll stand is constructed with varying resilience over the length thereof, particularly with a greater flattening behavior in at least a portion thereof. For this purpose, at least one of the rolls has in the area between the roll neck and the outer surface of the roll at least one notch extending concentrically about the axis.
