A section straightening machine is operated by a method which involves passing the structural sections through the array of straightening tools. Section straightening forces are applied to adjustable shafts carrying the tools and adjusters at the service sides of the shaft applying forces acting counter to the section straightening forces.

Method of operating a section straightening machine

The invention relates to a roll stand comprising a crown-variable-control (CVC) roll pair, preferably a CVC working roll pair and a back-up roll pair, which comprise a contact area (B cont) in which a horizontally active torque (M) acts that leads to a twisting of the rolls and thus to axial forces in the roll bearings. In order to keep the axial forces in the roll bearings as small as possible, the torque (M) is minimized by an appropriate CVC grinding.

The invention relates to a method for tension levelling a cold-rolled strip, whereby the strip passes through a series of break rolls and a series of traction rolls and in the course of its extension is subjected to traction between the two series of rolls. The strip is bent under traction in a series of high-traction rolls, located between the brake roll and the traction roll series, in order to increase the degree of levelling. To achieve this, the series of high-traction rolls between the brake and the traction rolls has at least two traction rolls for generating the strip traction and bending operation.

In a surface processing method for removing surface flaws, surface contaminants, and the like from a continuously cast metal product in a hot state, at least a portion of at least one metal product surface is cooled for a defined temperature decrease of a surface to be treated and a surface treatment is then performed. The device therefor has a cooling device for cooling at least a portion of at least one metal product surface for a defined temperature decrease of a surface to be treated and a surface treatment device downstream of the cooling device in the product conveying direction. The production arrangement for this has a continuous slab casting device, a heating arrangement with at least one of a heating device and a temperature equilibration device arranged downstream of the casting device. A hot mill train is arranged downstream of the heating arrangement in the conveying direction. The surface processing device for removing surface flaws, has a device for cooling at least a portion of at least one metal product surface for a defined temperature decrease of a surface to be treated and a surface treatment device downstream of the cooling device in the product conveying direction. The surface processing device is arranged between the casting device and the hot mill train.

A roll for a roll stand including a roll shaft with at least one roll ring mounted on the roll shaft, wherein the roll shaft is axially displaceable. The roll stand for rolling a metal strip may be, for example, a two-high stand, a four-high stand or six-high stand. The surfaces of at least two of the inner roll components enclosed by an outer roll ring have contours which are curved in the axial direction, wherein the curved contours are turned relative to each other by 180&deg;.

Roll for a roll stand

A roll, particularly a back-up roll, for rolling flat material is composed of a rotating roll shell and a unit arranged within the roll shell for influencing the bending stiffness of the roll shell. The unit for influencing the bending stiffness of the roll shell is a friction bearing in the form of a body of rotation. The body of rotation can be adjusted by rotating the body. The body of rotation is shaped in such a way that the load application surface thereof corresponding to the zone of the roll shell to which load is applied is part of the circumferential surface of a rotation-symmetrical body and the edge of this circumferential surface is shaped in such a way that along the circumference of the body of rotation the width and/or position of the load application surface vary.

Roll for influencing flatness

A roll stand for rolling strip includes work rolls which rest against back-up rolls through intermediate rolls, wherein the work rolls and/or the back-up rolls and/or the intermediate rolls are arranged so as to be axially slidable relative to each other, and wherein at least the work rolls and/or the intermediate rolls have a curved or cylindrical contour extending over the entire roll length. The work rolls and the intermediate rolls have at one of their end faces an annular recess extending around the roll neck, wherein the annular recess is located between the roll neck and the outer surface of the roll.
