Abstract: The invention relates to a roller device (50) having a stand and two roller sets having at least two rollers (52, 53, 54, 55) disposed in a stand (51) of the roller device, wherein a roll material (56) can be fed between two rollers (53, 54) of the two roller sets for rolling, wherein at least the rollers (52, 53) of a roller set can be displaced in the rolling direction relative to the stand (51), wherein adjustment means are provided between a roller bearing for receiving the rollers and the stand, each on both sides of the roller bearing. It is thereby particularly advantageous if the circumferential speeds of the rollers, such as the working rollers, are different.

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: A device for clamping a blade of shears for traverse cutting of strips includes a clamping bar for the clamping the blade, and a device for displacing the clamping bar in its release position, with the device having a first piston having a piston rod connected at its end remote from the piston with the clamping bar, and a second piston spaced from the first piston and having a piston rod section acting on the first piston, a first connection-bore connects the space in the front of the first piston with the space in the front of the second piston, and a second connection bores connects the space behind the second piston with the space behind the first piston, wherein the first and second connection bores are formed in the rod section of the second piston.

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: 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: 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: 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.
