Definitions

  • the invention relates to a method for selectively influencing the geometry of a rolling stock, wherein the rolling stock is transferred from an initial state by rolling by means of a roll stand by means of at least one processing unit in an intermediate or final state.
  • the invention further relates to a control and / or regulating device, a machine-readable program code and a data carrier.
  • hot rolling mills In a rolling mill all the equipment needed for the production of rolled products can be combined. Depending on the type of forming hot and cold rolling mills are differentiated.
  • slabs or ingots, usually called slabs for short, are processed to hot strip.
  • This hot forming is one of the methods that follows the original forming (ingot casting, continuous casting).
  • the rolling stock is heated to temperatures up to 1350 ° C and preferably reduced above its recrystallization temperature in a rolling nip of the rolling mill by pressure to a predetermined thickness.
  • the rolling stock to be rolled in a roughing train has a thickness progression across its width.
  • the aim is usually to produce by means of rolling bands, on the one hand at the end of the finishing line have a substantially symmetrical to the band center thickness across the width, ie are free of wedges, and on the other hand have the least possible bending over the length of the rolling stock, ie are saber-free.
  • a rolling stock is to be rolled, which is already wedge-shaped in the first rolling within the hot rolling line.
  • the wedging of the rolling stock usually results from the casting process and the subsequent cooling and further processing, in particular halving, of the cast slabs.
  • a wedge-shaped rolling stock is to be rolled out into a slab having a substantially rectangular cross-section, the volume flow on the "thicker" side of the slab results in a greater flow of material, in particular longitudinal flow, than on the "thin" side of the slab.
  • the consequence of this different material flow in the longitudinal direction of the rolling stock is the formation of a saber shape or a saber.
  • a saber-shaped rolling stock can lead to difficulties in subsequent processing of the rolling stock.
  • the formation of the saber can be so strong that further processing of the rolling stock is impossible.
  • position-controlled processing units for applying a transverse force are known, for example side guides as in the W02006 / 119984 described or vertical frameworks (so-called Edger) for width control.
  • the invention has for its object to provide an improvement in the geometry of a rolling stock, in particular when processing asymmetric rolling stock.
  • the object is achieved by a method for selectively influencing the geometry of a rolled stock, in particular a Vorbands, wherein the rolling stock is transferred from an initial state by rolling by means of a rolling mill, in particular a roughing stand, by means of at least one processing unit in an intermediate or final state and wherein the at least one processing unit is operated under power control based on a desired force.
  • the invention is based on the recognition that an asymmetrical course of the rolling stock can be counteracted particularly successfully by means of a suitably chosen force with which the processing unit acts on the rolling stock.
  • This force is defined by the desired force, while the desired force is a constant force or alternatively a variable over time force curve.
  • the previously applied position control of the at least one processing unit is unsuitable for the operation of the processing unit. Instead, the processing unit exerts a defined transverse force on the rolling stock through the power regulation, which influences the curvature of the material. This makes it possible that by means of the force control of the at least one processing unit is processed in terms of its thickness and / or width asymmetric rolling, so that the asymmetry is eliminated or at least largely reduced.
  • the force control can also be done with subordinate position control, ie the position is in a second, superimposed Control circuit used to regulate the setpoint force.
  • Such cascade controls are known in the art.
  • one processing unit is force-controlled and the other processing unit is operated position-controlled.
  • the position-controlled processing unit is tracked in such a way the power-controlled processing unit, that a midpoint between the two processing units always remains in a predetermined position. If the desired force to be applied is overestimated, a pure force control can lead to an unwanted distortion of the material of the rolling stock, in which the saber changes its direction. To avoid this, the position-controlled processing unit is moved closer to the rolling stock and absorbs the excessive force of the power-controlled processing unit.
  • the tracking of the position-controlled processing unit is implemented by control technology, by the center between the two processing units is not moved, but in particular always remains in the same place.
  • the midpoint between the two processing units expediently deviates from a center line of the roll stand, but it can also lie on the center line of the roll stand.
  • the center between the processing units and a distance between the processing units are used for the control of the processing units.
  • the center between the processing units is specified and the force control of one of the processing units via the adjustment of the distance between the processing units.
  • This type of force control in which the center and the distance between the two processing units are the control variables, is particularly easy to implement. In particular, since the center remains constant, only the distance between the changed both processing units. If this shifts the force-controlled processing unit, the position-controlled processing unit is tracked to compensate for a possibly much higher target force.
  • the at least one processing unit is initially moved to the rolling stock in a position-controlled manner, and when the desired force is reached by the reaction force acting on the processing unit, the system is switched over to the force control. In the case of two parallel processing units positioned on both sides of the rolling stock, this means that initially the distance between the processing units is reduced in a position-controlled manner. As the processing units move toward one another, the reaction force exerted by the rolling stock on the processing units also increases. If the reaction force acting on the processing unit on the "thin" side of the rolling stock or on the side with the lower material flow, has reached the desired force, then the position control of this processing unit is switched to force control, so that the operations described above are performed ,
  • the wedging and / or saberiness of the rolling stock, in particular in the initial state is measured and on this basis the setpoint force is determined for the force regulation. If the desired force is determined and the center is known, the distance between the processing units is calculated and fed as a control variable to the processing units.
  • the geometry of the rolling stock may change such that the wedge or saber change their side or direction.
  • a change in the position of the wedging and / or the direction of the saberiness of the rolling stock is a change between the force-controlled and the position-controlled Processing unit. This means that when the saber shape changes its direction during the rolling process, the previously force-controlled processing unit is operated position-controlled from the point of inflection and the previously position-controlled processing unit is now operated with force control.
  • control and / or regulating device for selectively influencing the geometry of a rolling stock, with a machine-readable program code containing control commands and / or control commands, the control and / or regulating device for performing the method according to one of cause the above.
  • a machine-readable program code for a control and / or regulating device for selectively influencing the geometry of a rolling stock which contains control commands and / or control commands, the control and / or regulating device for performing the method according to one of cause the above.
  • a horizontal rolling stand 2 in particular a roughing stand, shown, by means of which a rolling stock 4, in particular a pre-strip, is rolled, so that the rolling stock 4 is transferred from an initial state to an intermediate or final state.

  • S the distance between the processing units 6, 8.
  • a center line 10 of the roll stand 2 a center line 12 between the processing units 6, 8, and a center 14 between the processing units 6, 8, which lies on the center line 12 shown.
  • ⁇ s also denotes an offset between the two center lines 10 and 12.
  • the rolling stand 2 is operated in the embodiment shown in particular reversible, so that the rolling stock 4 changes its rolling direction 16 several times during operation.
  • the processing units 6, 8 in the rolling direction 16 downstream of the rolling mill 2.
  • the function of the processing units 6, 8 is to suppress an asymmetrical geometry of the rolled rolled stock 4.
  • one of the processing units 6, 8 in the embodiment of FIG. 2 the processing unit 6) is operated with force control, which is indicated by the desired force signal F.
  • the second processing unit 8 is operated position-controlled, indicated by the position signal P. the control of both processing units 6, 8 assumes a control device 18, the in FIG. 2 is shown symbolically.
  • the force-controlled machining unit 6 counteracts the wedge or the saber shape with a desired force F, which is determined on the basis of the geometry of the rolling stock 4.
  • a desired force F which is determined on the basis of the geometry of the rolling stock 4.
  • FIG. 2 merely contacts the processing unit 6, the rolling stock 4, the second processing unit 8 is moved at a distance from the rolling stock 4.
  • the two processing units 6, 8 are adjusted so that the position-controlled processing unit 8 is tracked to the power-controlled processing unit 6, wherein the offset ⁇ s remains constant.
