Definitions
- the invention relates to a side guide for a rolling train and a rolling train with at least one side guide.
- rolling mills In rolling mills rolled goods, for example slabs, are rolled into material strips or sheets of a specific thickness in so-called rolling mills.
- rolling mills have rolling mills, in which the rolled goods are guided through nips between scaffold rollers.
- Rolling mills often also have side guides for laterally guiding the rolling stock along the rolling mills.
- the invention has for its object to provide an improved side guide for a rolling train and an improved rolling mill, in particular for processing asymmetric rolling stock.
- the object is achieved with respect to the side guide by the features of claim 1 and with respect to the rolling train by the features of claim 9.
- a lateral guide according to the invention for a rolling train comprises a band element and a transverse force device attached to the band element.
- the band element is designed for the at least partial lateral delimitation of a transport path of the rolling train along a longitudinal axis of the band element.
- the lateral force device has a force-generating unit for generating a transverse force orthogonal to the longitudinal axis of the band element and a force transmission unit coupled to the force-generating unit for transmitting the transverse force to a rolling stock passed through the rolling line.
- Such a lateral guide makes it possible to exert a transverse force on a rolling stock by means of the transverse force device at a defined location. As a result, it is possible to influence and set very precisely a moment exerted on the rolling stock by means of the transverse force and a resulting tension distribution in a roll gap of a roll stand. In particular, this makes it possible, by means of the lateral guide or its transverse force device, to process an asymmetrical rolling stock with regard to its thickness and / or width, so that the asymmetry is eliminated or reduced, as will be explained in more detail below with reference to an exemplary embodiment.
- a lateral guide according to the invention makes it possible to selectively generate and transfer a transverse force to a rolling stock, in particular to reduce asymmetry of the rolling stock.
- a lateral force device of a lateral guide according to the invention can be placed closer to a rolling nip of a rolling stand than a compression device and therefore exert a transverse force which acts on a greater proportion of a rolling stock than a compression device.
- the generation of a transverse force by means of an entire side guide has the disadvantage that the transverse force is transmitted only over a large area and not at a defined point, so that in contrast to the power transmission according to the invention by means of a lateral force device of a side guide the force exerted by the lateral force moment and the generated train distribution not are known exactly.
- the power transmission unit is a roller with a to the longitudinal axis of the band member and to the direction of the transverse force orthogonal longitudinal axis.
- the roller is also preferably rotatably mounted about its longitudinal axis.
- Such a role is particularly suitable as a power transmission unit, since it is a particularly simple, inexpensive and efficient means for transmitting a lateral force to a rolling stock.
- the force-generating unit is preferably a hydraulic or pneumatic cylinder acting on the power transmission unit or a mechanically-electrically driven screw acting on the power transmission unit.
- All of these force generating units advantageously enable a controlled and precise generation of a transverse force and its transmission to a power transmission unit.
- the lateral guide has a drive device for displacing the band element parallel to the transverse force.
- the transverse force device can be approached to the rolling stock by causing large movements of the transverse force device by moving the band element and the force transmission unit only has to be moved over a relatively short distance through the force generating unit to the rolling stock.
- This makes it possible to keep the dimensions of the transverse force device relatively small.
- this has the advantage that the transverse force device can be arranged relatively close to the nip of a roll stand.
- it advantageously reduces material, effort and costs for producing the transverse force device.
- the lateral guide preferably has a braking device by means of which a displacement of the band element parallel to the transverse force can be blocked.
- a rolling train according to the invention comprises a transport path for transporting a rolling stock, at least one rolling stand and at least one lateral guide according to the invention.
- each such lateral guide is arranged laterally on the transport path, so that the band element of the side guide limits the transport path at least partially laterally along a longitudinal axis of the band element and the transverse force device exerts a transverse force on the rolling stock.
- Such a rolling train allows the processing of a rolling stock by means of a side guide according to the invention with the advantages already mentioned above.
- Each lateral force device of a lateral guide is preferably arranged on an end section of the respective lateral guide, which faces an adjacent rolling stand.
- the distances of the transverse force devices are advantageously reduced to the roll nips of the rolling stands, so that the transverse forces generated by the transverse force devices can act on the largest possible areas of a rolling stock.
- a rolling train has at least two pairs of side guides, wherein the two side guides of each pair are arranged on different sides of the transport path and the two pairs are arranged on different sides of a rolling stand.
- Such an arrangement makes it possible to exert lateral forces on a rolling stock both before and behind a rolling stand and on each side of the rolling train, thus enabling a particularly flexible generation of transverse force.
- the rolling train on a compression device for reducing a width of the rolling stock and each side guide is arranged on a side facing away from the compression device side of a rolling stand.
- This embodiment of the invention takes into account that in rolling mills with compression devices an arrangement of a side guide according to the invention between a compression device and a rolling mill is impractical, since thereby the effect of the compression device and / or the side guide is reduced.
- a further embodiment of the invention provides to arrange all side guides on the same side of the transport path.
- This embodiment of the invention is advantageous if the rolling stock can be pre-sorted into the rolling train in such a way that a transverse force is required only on one side of the rolling train. As a result, in particular, the number of required lateral force devices can be reduced.
- FIG. 1 schematically shows a section of a rolling train 1 with a rolling stand 2, a compression device 3 and side guides 4, 5, 6, 7. Also shown is a rolling stock 8, which in a rolling direction shown by an arrow over a transport path of the rolling mill 1 by the rolling mill 1 is guided while being rolled.
- the rolling direction defines an X-direction of a Cartesian coordinate system with Cartesian coordinates X, Y, Z.
- the Y-direction of this coordinate system runs in the plane of the drawing FIG. 1 orthogonal to the X direction, the Z direction is perpendicular to this plane.
- the compression device 3 comprises two compression rollers 3.1, which are arranged opposite each other on different sides of the transport path, each having a longitudinal axis extending in the Z direction and are rotatably mounted about this longitudinal axis. At least one of the compression rollers 3.1 is displaceable in the Y direction, so that its outer surface can be moved up to the rolling stock 8.
- a width of the rolled material 8, i. an expansion of the rolling stock 8 in the Y direction can be reduced.
- the rolling stock 8 can be aligned and guided by means of the compression device 3 in the Y direction.
- the roll stand 2 comprises at least two stacking rollers 2.1 arranged one above the other, each having a longitudinal axis extending in the Y direction and being rotatably mounted about this longitudinal axis.
- the stand rollers 2.1 are spaced apart by an adjustable roll gap, through which the rolling stock 8 is passed to reduce its thickness, wherein the thickness of the rolling stock 8 is its extension in the Z direction.
- the roll stand 2 is located behind the compression device 3, wherein the position information "before” and “behind” here and hereinafter refer to the arrangement along the rolling direction.
- the side guides 4, 5, 6, 7 each have a band element 4.1, 5.1, 6.1, 7.1 for the partial lateral boundary the transport path along a longitudinal axis extending in the X direction of the respective band element 4.1, 5.1, 6.1, 7.1.
- a first side guide 4 and a second side guide 5 are arranged in front of the compression device 3 opposite to each other on different sides of the transport path.
- a third side guide 6 and a fourth side guide 7 are arranged behind the rolling stand 2 opposite to each other on different sides of the transport path.
- the fourth side guide 7 has a mounted on its band element 7.1 transverse force device 9 with a force generating unit 9.1 and a power transmission unit 9.2.
- the force generating unit 9.1 is designed as a hydraulic cylinder.
- the power transmission unit 9.2 is designed as a roller with a Z-direction extending longitudinal axis about which the roller is rotatably mounted.
- the fourth side guide 7 also has a drive device, not shown, for displacing its band element 7.1 parallel to the transverse force.
- the transverse force device 9 can be approached to the rolling stock 8 by large movements of the transverse force device 9 are caused by moving the belt element 7.1 and the role only over a relatively short distance through the hydraulic cylinder to the rolling stock 8 must be moved, so that advantageously a hydraulic cylinder can be used with a relatively small stroke.
- the lateral force device 9 is mounted on a rolling stand 2 facing the end portion of the fourth side guide 7 at a defined distance close behind the nip of the roll stand 2.
- the transverse force generated by the transverse force device 9 can advantageously be applied very precisely and over large areas of the rolling stock 8, since only sections of the rolling stock 8 at its beginning and end whose extent in the X direction corresponds to the distance of the roll gap from the transverse force device 9, can not be influenced by the lateral force.
- the transverse force device 9 can be arranged closer to the roll gap of the roll stand 2 than the compression device 3.
- FIG. 2 shows a cross section of an asymmetric rolling stock 8 before its processing in the rolling mill 1.
- the thickness of the rolled material 8 decreases in the Y direction, so that the cross section is wedge-shaped.
- Such a rolling stock 8 can be advantageous in the in FIG. 1 Walz No 1 are processed.
- the rolling stock 8 is inserted into the rolling train 1 such that its thinner side is oriented to that side of the rolling train 1 on which the fourth side guide 7 with the transverse force device 9 is arranged. If the stand rollers 2.1 are not pivoted against each other in the X direction, the thicker areas of the rolling stock 8 in the rolling stand 2 result in a greater elongation than originally thinner areas due to the inhomogeneous thickness of the rolling stock. As a result, the rolling stock 8 would be behind the rolling stand without the use of a transverse force 2 to the side of the rolling mill 1 to bend down, where the fourth side guide 7 is arranged. This curvature can be prevented or at least reduced by the transmission of a transverse force to the rolling stock 8 by means of the transverse force device 9.
- the rolled goods 8 are pre-sorted prior to insertion into the rolling train 1, so that their thinner sides are respectively oriented to the same side of the rolling train 1, on which the fourth side guide 7 is arranged with the transverse force device 9.
- the embodiment described above can be modified in that the force-generating unit 9.1 is designed as a pneumatic cylinder or a mechanically-electrically driven screw. Furthermore, several or all lateral guides 4, 5, 6, 7 can also be equipped with a transverse force device 9, in particular if a rolling train 1 does not comprise a compression device 3.
