Definitions

  • the present invention relates to a method and a system for winding a continuously produced metal strip.
  • ESP endless strip production
  • This process involves rolling a continuously cast metal strand to the desired thickness immediately downstream of a corresponding casting machine.
  • Strip produced in this way is typically cut for storage and transport, and the resulting strip sections are wound into metal bundles, so-called “coils,” using reels (often referred to as “down coilers”).
  • reels often referred to as “down coilers”
  • several reels are provided, to which the strip sections can be selectively fed.
  • a movable guide roller of a pair of guide rollers arranged directly in front of the currently active reel can be moved during operation in such a way that the new strip section is transported past this reel to the other reel.
  • KR 2015 0073016 A discloses a downward clamping roller provided between a material distributor and a reel.
  • a pressure roller and a lateral guide arranged downstream between the material distributor and the reel can be omitted.
  • DE 196 20 696 A1 concerns the allocation of individual batches of rolling stock to respective reels and proposes that a driver be arranged downstream of a flying shear, the rollers of which can be displaced in such a way that the plane defined by the two axes of the rollers can be pivoted from a substantially vertical position in such a way that a normal standing on this plane is pivoted in the direction of the first of the downstream reels.
  • KR 100 470 642 B1 relates to the guiding of the leading and trailing ends of a strip produced in a steel mill using a plurality of tensioning reels.
  • a strip guide roller and a bending roller are provided, which are movable above a deflection roller in the circumferential direction of the deflection roller.
  • a metal strip is guided over a guide roller of a guide roller pair positioned in a first roller position along a first transport path to a first reel and cut upstream of the guide roller pair. Furthermore, the guide roller of the guide roller pair is repositioned to a second roller position, in which the metal strip is guided over the guide roller along a second transport path to at least one second reel. According to the invention, the repositioning of the guide roller takes place either before or after the cutting of the metal strip, depending on the thickness of the metal strip and/or the transport speed of the metal strip.
  • Upstream in the sense of the present invention, is preferably understood as "before" with respect to a transport direction.
  • a cutting device is provided that is arranged upstream of the guide roller pair, a metal strip section first passes through the cutting device before reaching the guide roller pair.
  • One aspect of the invention is based on the approach of moving a repositionable guide roller of a pair of guide rollers at a time that depends on the thickness and/or transport speed of a metal strip to be wound.
  • the time is expediently coordinated with the time at which the metal strip is cut.
  • the time can be selected such that even with thick metal strips with a strip thickness of 6-13 mm or more, no undesirable impairment of the metal strip and/or a system component occurs, for example, due to contact of the metal strip with a component of the reel feed or a reel shaft.
  • the point in time at which the guide roller is moved can be before or after the point in time at which the metal strip is cut.
  • the pair of guide rollers does not fulfill any guiding function during the repositioning of the guide roller, and undesired contact of the metal strip running over the guide roller during normal operation (thick) metal strip with a component of the reeling device, in particular the guide shaft, can be prevented.
  • the size of the gap that can be created when cutting the metal strip preferably corresponds to the transport speed of the metal strip.
  • the transport speed usually depends on the thickness of the metal strip. Consequently, with a thick metal strip, the gap can be large enough to allow the guide roller to be repositioned in a "contact-free" state.
  • the guide roller is preferably repositioned at a time interval from the cutting of the metal strip.
  • a predetermined waiting time can be waited from the time the metal strip is cut before the guide roller is repositioned.
  • the time interval or the predetermined waiting time expediently depends on the thickness of the metal strip and/or the transport speed of the metal strip.
  • the time interval or the waiting time can then correspond exactly to the time required for the gap between the two metal strip ends created during cutting to reach the pair of guide rollers.
  • the decision as to whether the guide roller should be repositioned before or after the metal strip is cut should depend on whether the gap between the metal strip ends is sufficient for the guide roller to be repositioned. Therefore, it is preferable to check whether the travel time required to reposition the guide roller is greater than the time during which the guide roller pair does not guide any metal strip after the metal strip has been cut, i.e., is "contact-free.”
  • the guide roller is preferably positioned based on a The result of this test is repositioned either before or after the metal strip is cut.
  • the test can be reliably carried out as follows:
  • the travel time required to reposition the guide roller is compared with a difference between a first time period and a second time period.
  • the first time period is expediently defined by the cutting of the metal strip, on the one hand, and the arrival of a head end of the subsequent metal strip section at the guide roller pair, on the other.
  • the second time period is expediently defined by the cutting of the metal strip, on the one hand, and the exit of a foot end (also referred to as the "tail end") of the preceding metal strip section from the guide roller pair, on the other.
  • the difference between the first and second time periods therefore indicates the period of time during which no metal strip runs over the guide roller.
  • the guide roller is preferably repositioned before the metal strip is cut. However, if the test shows that the difference between the first and second time periods is greater than the process time, the guide roller can also be repositioned after the metal strip has been cut without interrupting system operation. Performing a test to determine whether the guide roller should be repositioned before or after the metal strip has been cut enables flexible system operation with a wide range of strip thicknesses.
  • the decision as to whether the guide roller should be repositioned before or after cutting the metal strip can also be made with minimal effort using a look-up table.
  • a look-up table can be used to determine at which strip thicknesses and/or transport speeds repositioning should occur before cutting and at which strip thicknesses and/or transport speeds repositioning should occur after cutting the metal strip.
  • the strip thickness and/or the transport speed can be calculated using an automation unit, for example, in so-called electrical and automation (EA) precalculations for the configuration of the system components.
  • EA electrical and automation
  • these parameters can also be measured using a sensor unit, for example, one or more sensors in a so-called measuring hut.
  • strip thickness and/or transport speed determined in this way can also be used as the basis for the test described above, in particular for determining the first and/or second time period.
  • the transport speed on the first transport path is preferably increased after the metal strip has been cut.
  • the gap created when the metal strip is cut between the preceding metal strip section and the following metal strip section can be created with a predetermined size, in particular a minimum size.
  • This increase in transport speed is therefore particularly advantageous if the guide roller is not repositioned until after the metal strip has been cut.
  • the increase in transport speed on the first transport path is accompanied by an increase in the winding speed of the first reel.
  • the transport speed on the first transport path can be achieved by increasing the winding speed of the first reel.
  • the preceding metal strip section can thus be accelerated compared to the following metal strip section and a gap created when the metal strip is cut can be enlarged, so that more time is available for repositioning the guide roller.
  • the winding method according to the invention can be advantageously used across a wide range of thicknesses.
  • metal strips with a thickness between 0.5 mm and 30 mm can be wound without any problems. Therefore, it is advantageous that, as part of the method, the metal strip is produced in a continuous process by a combined casting and rolling plant, i.e., within the framework of an ESP, so that the metal strip, upon reaching the pair of guide rollers, has a thickness of at least 0.5 mm, preferably at least 0.8 mm, and/or up to 25.4 mm or more, preferably up to 30 mm or more.
  • the guide roller can be repositioned before cutting. Up to a strip thickness of, for example, 6 mm, the conventional winding method or a conventional change of the winding means can therefore be used. However, if the metal strip has a thickness of, for example, 13 mm or more, it is preferred that the guide roller is not repositioned until after the metal strip has been cut. This ensures that mechanical impairment of the metal strip and/or a system component, in particular a reel feed or reel shaft, is avoided. In particular, from a strip thickness of, for example, 6 mm, it may be possible to move the roller after the strip has been cut. From a strip thickness of, for example, 10-13 mm, it may be necessary to move the roller after the strip has been cut.
  • the preferred time for repositioning the guide roller may depend on the plant design, particularly the coiler design, or the plant operation.
  • the limit value for a strip thickness at which a displacement of the guide roller is possible and/or necessary after the strip is cut may depend on the casting or transport speed, the travel distance of an actuator for repositioning the guide roller, and/or the travel speed of the actuator.
  • Such a winding system is universally applicable for continuously produced metal strips with a wide range of strip thicknesses and/or (associated) transport speeds.
  • it can be used to wind both very thin metal strips, for example, with a strip thickness of approximately 1 mm or less, and very thick metal strips, for example, with a strip thickness of approximately 20 mm or more, in continuous operation. Consequently, the winding of even thick metal strips can be continued on a second reel without interrupting plant operation once the metal coil on a first reel has reached its target size.
  • the control device can be implemented in hardware and/or software.
  • the control device can, in particular, comprise a processing unit, preferably connected to a memory and/or bus system for data or signals.
  • the control device can comprise a microprocessor unit (CPU) or a module thereof and/or one or more programs or program modules.
  • the control device can be configured to process commands implemented as a program stored in a memory system, to acquire input signals from a data bus, and/or to output signals to a data bus.
  • a memory system can comprise one or more, in particular different, storage media, in particular optical, magnetic, solid-state, and/or other non-volatile media.
  • the program can be designed in such a way that it embodies or is capable of executing the methods described here, so that the control device can execute the steps of such methods and thus reposition the guide roller in a targeted manner before or after the metal strip is cut.
  • the system 1 can be part of a combined casting and rolling plant designed for so-called “endless strip production” (ESP), i.e., for the continuous production of the metal strip 2.
  • ESP endless strip production
  • a combined casting and rolling plant expediently also includes one or more rolling stands (not shown) in which the cast metal strand is rolled into the metal strip 2.
  • These transport means may, for example, comprise driven transport rollers.
  • the reels 20, 30 may also be at least part of these transport means, with the metal strip 2 being pulled along by winding on the corresponding reel 20, 30.
  • the transport means are expediently configured to transport the metal strip 2 along a transport direction 3.
  • this transport direction 3 runs at least substantially horizontally.
  • the first reel 20 is arranged downstream of the guide roller pair 10 and the second reel 30 is arranged downstream of the first reel 20, so that the guide roller pair 10 can guide the metal strip 2 optionally to the first reel 20 or to the second reel 30. If necessary, at least one further reel can also be provided downstream of the second reel 30.
  • the cutting device 40 is arranged upstream of the guide roller pair 10.
  • the first reel 20 is arranged below the pair of guide rollers 10, so that the metal strip 2 runs downwards over the guide roller 11 arranged below the metal strip 2 into a guide shaft 21 leading to the first reel 20.
  • the course of the metal strip 2 between the guide roller 11 and the first reel 20 defines a first transport path 22, which in FIG 1 indicated as a dotted oval.
  • first reel 20 could also be arranged above the guide roller pair 10.
  • metal strip 2 would be guided over the guide rollers arranged above the metal strip 2.
  • Guide roller 11 runs along the first transport path 22 upwards to the first reel 20.
  • the guide shaft 21 is formed by a first guide element 23, for example a chute or a guide table, and a second guide element 24, which may optionally also be designed to be movable, for example as a switch.
  • the pair of guide rollers 10 can also guide the metal strip 2 past the first reel 20 to the second reel 30.
  • the metal strip 2 is transported via the second guide element 24, which expediently has several transport rollers 25 on its upper side.
  • the second guide element 24 supports the metal strip 2 during transport to the second reel 30.
  • the path of the metal strip 2 over the second guide element 24 is shown in Figure 1 shown in dashed lines and defines a second transport path 32.
  • the position of the guide roller 11, in particular relative to the support roller 12, can be changed by actuating the actuator 70.
  • the guide roller 11 can be moved by means of the actuator 70 from a first roller position, in which the guide roller 11 is positioned upstream of the support roller 12 with respect to the transport direction 3, to a second roller position, in which the guide roller 11 and the support roller 12 are preferably at the same height with respect to the transport direction 3, or the guide roller 11 is even positioned downstream of the support roller 12.
  • the control device 50 can be configured to send a corresponding actuation signal to the actuator 70.
  • control device 50 is expediently designed to change the position of the guide roller 11 depending on the thickness of the metal strip 2 and/or the transport speed of the metal strip 2 before or after cutting the metal strip 2 by means of the cutting device 40.
  • Continuous winding of the metal strip 2 is understood to mean a change of the winding means, in particular from the first reel 20 to the second reel 30, which is carried out without interrupting the production process of the metal strip 2.
  • Information regarding the thickness and/or transport speed of the metal strip 2 can be received by the control device 50 from the sensor unit 60.
  • the sensor unit 60 is configured to measure the thickness and/or transport speed of the metal strip 2.
  • these parameters can also be determined, in particular calculated, by the control device 50 itself, for example, if the control device 50 is at least part of an automation unit.
  • FIG 2 shows a first roller position P1 and a second roller position P2 of a guide roller 11.
  • the guide roller 11 is positioned upstream of a support roller 12, with which the guide roller 11 forms a guide roller pair, with respect to a transport direction 3 of a metal strip 2 guided by the guide roller pair.
  • the guide roller 11 is preferably arranged at the same height as the support roller 12 with respect to the transport direction 3 or is positioned downstream of the support roller 12. This is indicated by the vertically drawn dashed line, which runs perpendicular to the transport direction 3.
  • the guide roller 11 is advantageously moved parallel to the transport direction 3.
  • the travel distance d covered is preferably quite large compared to a thickness of the metal strip 2 of a few millimeters, so that the guide roller pair can reliably guide a head end 4 of the metal strip 2 into a guide shaft 21 to a first reel (not shown) when the guide roller 11 is in the first roller position P1.
  • the travel distance d can, for example, be approximately ten to one hundred times the strip thickness.
  • a typical travel distance d is approximately 200 mm to 350 mm.
  • the metal strip 2 runs through the guide shaft 21 on a first transport path 22 indicated by a dashed line.
  • the guide shaft 21 is delimited on one side by a second guide element 24.
  • a gap 26 between the guide roller 11 in the second roller position P2 and the second guide element 24 must be very narrow, for example 10 mm or less, so that a head end 4 of a very thin metal strip 2 can be guided from the guide roller 11 over the gap 26 onto a second transport path 32, also indicated by a dashed line, to a second reel (not shown). If the width of the gap 26 is chosen to be too large, there is a risk that the very thin metal strip 2 will bend too much due to its own weight and that its head end 4 will strike the second guide element 24 laterally instead of running along its surface.
  • the guide roller 11 can therefore only be positioned in the second roller position P2 when no more metal strip 2 passes through the guide shaft 21 or at least no more metal strip 2 is arranged between the guide roller 11 and the second guide element 24.
  • the exact strip thickness at which the guide roller 11 can be moved after cutting the metal strip 2 depends on the casting speed and thus also the transport speed. At low speeds, the strip can be thinner; at high casting speeds, this is only possible with thicker strip thicknesses.
  • FIG 3 shows an example of a metal strip divided into a preceding metal strip section 2a and a following metal strip section 2b.
  • the preceding metal strip section 2a runs over a guide roller 11 of a guide roller pair 10 on a first transport path 22 to a first reel 20.
  • the guide roller 11 is positioned in a first roller position. In this first roller position, the guide roller 11 is positioned upstream of a support roller 12 of the guide roller pair 10 with respect to a transport direction 3.
  • Gap L is formed.
  • the gap L can be further increased after cutting, for example by increasing the winding speed of the first reel 20.
  • the guide roller 11 By forming the gap L, sufficient time can be gained to position the guide roller 11 in a second roller position, in which the guide roller 11 is preferably at the same height as the support roller 12 with respect to the transport direction 3 or is even located downstream of the support roller 12, before the head end 4 of the subsequent metal strip section 2b reaches the guide roller pair 10. It is expedient to start repositioning the guide roller 11 only after the foot end 5 of the preceding metal strip section 2a has left the guide roller pair 10. If the metal strip is a thick metal strip with a strip thickness of more than 6-13 mm, for example, this can prevent the preceding metal strip section 2a from becoming clamped between the guide roller 11 and a second guide element 24 arranged downstream of the guide roller pair 10.
  • FIG 4 shows an example of a method 100 for winding a metal strip 2.
  • a process step S1 the metal strip 2 is guided to a first reel 20 by means of a pair of guide rollers 10.
  • the metal strip 2 runs over a guide roller 11 of the pair of guide rollers 10, which is located in a first roller position, on a first transport path 22 to the first reel 20.
  • step S3a the winding speed of the first reel 20 and thus the transport speed on the first transport path 22 are expediently increased simultaneously or at least immediately after the metal strip 2 has been cut.

  • the end of this time window is defined by the arrival of the head end 4 of the subsequent metal strip section 2b at the guide roller pair 10.
  • the guide roller 11 is already in the second roller position. Accordingly, in a further process step S5a, the guide roller pair 10 guides the subsequent metal strip section 2b along a second transport path 32 to a second reel (not shown). The preceding metal strip section 2a wound using the first reel 20 can be removed, thus preparing the first reel 20 for reuse.
  • the guide roller 11 is first moved to the second roller position in a further process step S3b. This is indicated by the arrow.
  • the metal strip 2 can be cut using the cutting device 40. This takes place in the further process step S4b.
  • the subsequent metal strip section 2b is guided onto the second transport path 32.

  • Whether the time window in which the guide roller pair 10 is not guiding a metal strip 2 is sufficient to reposition the guide roller 11 depends largely on the transport speed at which the preceding metal strip section 2a is transported and the transport speed at which the subsequent metal strip section 2b (on the first transport path 22) is transported.
  • the transport speed of the subsequent metal strip section 2b is usually constant and corresponds to the thickness of the metal strip 2, since the mass flow is constant in a continuously produced metal strip 2.
  • the transport speed of the preceding metal strip section 2a can - since the metal strip 2 is divided - be adjusted independently, for example via the winding speed of the first reel 20. However, this is usually limited.
  • the transport speed of the preceding metal strip section 2a can only be slightly higher than the speed determined by the manufacturing process of the metal strip 2
  • the predetermined transport speed of the subsequent metal strip section 2b can be increased.
  • test in process step S2 can be based on the thickness of the metal strip 2 and/or the transport speed.
  • decision in process step S2 as to whether the guide roller 11 should be moved before or after the metal strip 2 is cut can also be made by consulting a lookup table containing instructions regarding the time of repositioning the guide roller 11 depending on the strip thickness and/or the transport speed.
