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.

Multipart roller

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.

Method for producing a support roll for a rolling mill

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

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.

Method of operating a flying shear

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.
