Definitions
- the present invention relates to a method and a system for winding a continuously produced metal strip.
- ESP endless strip production
- a continuously cast metal strand is rolled to the desired strip thickness immediately behind a corresponding casting plant.
- a strip produced in this way is usually cut up 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 optionally fed.
- a movable guide roller of a pair of guide rollers arranged immediately 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 that is provided between a material distributor and a reel. A pressure roller and a side guide arranged subsequently between the material distributor and the reel can be dispensed with.
- DE 196 20 696 A1 concerns the allocation of individual lots of rolling stock to respective reels and proposes to arrange a driver downstream of a flying shear, the rollers of which can be displaced in such a way that the plane laid through 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 front and rear ends of a strip which is produced in a steelworks 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 is cut upstream of the guide roller pair.
- 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 two- ten reel.
- the repositioning of the guide roller takes place depending on a thickness of the metal strip and/or a transport speed of the metal strip either before or after the metal strip is cut.
- Upstream in the sense of the present invention is preferably to be understood as "before” with regard to a transport direction. If, for example, a cutting device is provided which is arranged upstream of the guide roller pair, a metal strip section first passes the cutting device before it reaches 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 a thickness and/or a transport speed of a metal strip to be wound.
- the time is expediently timed to coincide with a time at which the metal strip is cut.
- the time can be selected in such a way that even with thick metal strips with a strip thickness of 6-13mm 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.
- a gap can be created between the two metal strip ends created during cutting. If the gap is large enough, the guide roller can be repositioned while the gap passes the pair of guide rollers. In this case, the pair of guide rollers does not perform a guiding task while the guide roller is being repositioned, and unwanted contact of the (thick) metal strip running over the guide roller during normal operation with a system component of the reeling device, in particular the guide shaft, can be prevented.
- the size of the gap that can be created when the metal strip is cut preferably corresponds to the transport speed of the metal strip. Basically, the lower the transport speed, the larger the gap that can be created. Since the volume flow remains constant in a continuous casting process, the transport speed usually depends on the thickness of the metal strip. As a result, the gap can be large enough for a thick metal strip to enable the guide roller to be repositioned in a "contact-free" state.
- the guide roller is preferably repositioned at a certain time interval from the cutting of the metal strip. For example, from the time at which the metal strip is cut, a predetermined waiting time can be waited 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 period that the gap between the two metal strip ends created during cutting needs 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 ends of the metal strip is sufficient to reposition the guide roller. It is therefore preferable to check whether the travel time required to reposition the guide roller is longer than the time during which the pair of guide rollers does not guide any metal strip after the metal strip is cut, i.e. is "contact-free".
- the guide roller is expediently repositioned either before or after the metal strip is cut based on the result of this test.
- 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 hand.
- 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 on the other hand. also referred to as the "tail end") of the preceding metal strip section from the guide roller pair on the other hand.
- the difference between the first and second time periods therefore indicates the time period for which no metal strip runs over the guide roller.
- the guide roller is preferably repositioned before the metal strip is cut. If, however, 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 having to interrupt system operation. Carrying out a test to determine whether the guide roller should be repositioned before or after the metal strip has been cut enables flexible operation of the system with a wide range of strip thicknesses.
- the decision as to whether the guide roller should be repositioned before or after the metal strip is cut can also be made with little effort using a look-up table.
- a look-up table can be used to determine at which strip thicknesses and/or transport speeds the repositioning should take place before cutting and at which strip thicknesses and/or transport speeds the repositioning should take place after the metal strip is cut.
- the strip thickness and/or the transport speed can be calculated using an automation unit, for example in so-called electric and automation (EA) pre-calculations for the configuration of the system components.
- EA electric and automation
- these parameters can also be measured using a sensor unit, for example using 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 that arises 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 the transport speed is therefore particularly advantageous if the guide roller is only repositioned after the metal strip has been cut.
- the increase in the 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 used advantageously over a wide range of thicknesses.
- metal strips with a thickness between 0.5 mm and 30 mm can be wound without any problems. It is therefore 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 has a thickness of at least 0.5 mm, preferably at least 0.8 mm and/or up to 25.4 mm and more, preferably up to 30 mm and more, when it reaches the guide roller pair.
- 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 only repositioned 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 a 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 can depend on the system design, in particular the reel design, or the system operation.
- the limit value for a strip thickness from which a displacement of the guide roller is possible and/or necessary after the strip has been cut can depend on the casting or transport speed, the travel path of an actuator for repositioning the guide roller and/or the travel speed of the actuator.
- a system for winding a continuously produced metal strip comprises: (i) a guide roller pair with a repositionable guide roller; (ii) a first reel arranged downstream of the guide roller pair; (iii) at least one second reel arranged downstream of the first reel; (iv) at least one cutting device arranged upstream of the guide roller pair for cutting the metal strip; and (v) a control device which is designed to reposition the guide roller from a first roller position to a second roller position in accordance with Depending on a thickness of the metal strip and/or a transport speed of the metal strip, the cutting can be carried out either before or after the metal strip is cut by means of the cutting device.
- the metal strip In the first roller position, the metal strip can be guided along a first transport path to the first reel.
- the metal strip In the second roller position, the metal strip can be guided along a second transport path to at least one second reel.
- Such a winding system can be used universally for continuously produced metal strips with a wide range of strip thicknesses and/or (associated) transport speeds.
- both very thin metal strips for example with a strip thickness of around 1 mm or less
- very thick metal strips for example with a strip thickness of around 20 mm or more
- the winding of even thick metal strips can be continued on a second reel without interrupting system operation when the metal coil on a first reel has reached its specified size.
- the system preferably has an actuator for repositioning the guide roller, the actuation of which allows the guide roller to be moved from the first to the second roller position and/or from the second to the first roller position.
- the control device can therefore be set up to send a corresponding actuation signal to the actuator.
- the control device preferably decides, for example by means of a corresponding control logic, on the basis of the strip thickness and/or the transport speed, whether the actuation signal is sent before or after the metal strip is cut.
- the control device can determine the strip thickness and/or the transport speed itself, for example if the control device is at least part of an automation unit.
- the control device can access sensor data which characterize the strip thickness and/or the transport speed and which can be provided by a sensor unit.
- the control device can be designed in terms of hardware and/or software.
- the control device can in particular have a processing unit, preferably data- or signal-connected to a memory and/or bus system.
- the control device can have a microprocessor unit (CPU) or a module of such and/or one or more programs or program modules.
- the control device can be designed to process commands that are implemented as a program stored in a memory system, to detect input signals from a data bus and/or to output signals to a data bus.
- a memory system can have 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 carrying out the methods described here, so that the control device can carry out the steps of such methods and thus with which the guide roller can be repositioned at a specific time before or after the metal strip is cut.
- FIG 1 shows an example of a system for winding a continuously produced metal strip
- FIG 2 shows a first roller position and a second roller position of a guide roller
- FIG 3 shows an example of a divided metal strip with a gap formed by increasing a winding speed of a preceding metal strip section
- FIG 4 shows an example of a method for winding a metal strip.
- FIG 1 shows an example of a system 1 for winding a continuously produced metal strip 2 with a pair of guide rollers 10 with a repositionable guide roller 11 and a support roller 12, a first reel 20, a second reel 30, a cutting device 40 for cutting the metal strip 2, a control device 50, a sensor unit 60 and an actuator 70 for repositioning the guide roller 11.
- the control device 50 is expediently connected to the cutting device 40, the sensor unit 60 and the actuator 70 by data or signals.
- the system 1 can be part of a combined casting and rolling plant which is set up for so-called “endless strip production” (ESP), ie for the continuous production of the metal strip 2.
- ESP endless strip production
- a combined casting and rolling plant expediently also comprises one or more rolling stands (not shown) in which the cast metal strand is rolled into the metal strip 2.
- the system 1, and possibly also the combined casting-rolling plant expediently has means (not shown) for transporting the metal strip 2.
- These transport means can, for example, comprise driven transport rollers.
- the reels 20, 30 can 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 designed 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 guide roller pair 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 is indicated in FIG 1 as a dotted oval.
- the first reel 20 could also be arranged above the guide roller pair 10.
- the metal strip 2 would run over the guide roller 11 arranged above the metal strip 2 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 dashed lines in Figure 1 and defines a second transport path 32.
- the guide roller 11 is positioned upstream relative to the support roller 12 in relation to the transport direction 3, ie the axis 11a of the guide roller 11 is arranged upstream of the axis 12a of the support roller 12, the incoming head end of the metal strip 2 is directed onto the first transport path 22. If the guide roller 11 and the support roller 12 are at the same height with respect to the transport direction 3 or if the guide roller 11 is downstream of the support roller 12, ie if the axis Ha of the guide roller 11 is downstream of the axis 12a of the support roller 12, the incoming head end of the metal strip 2 is directed onto the 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 relative to the support roller 12 in relation 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 in relation 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 set up to send a corresponding actuation signal to the actuator 70.
- control device 50 is expediently designed to cause a change in the position of the guide roller 11 depending on a thickness of the metal strip 2 and/or a transport speed of the metal strip 2 before or after the metal strip 2 is cut by means of the cutting device 40.
- Continuous winding of the metal strip 2 is to be understood as 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.
- the circumstances under which the guide roller 11 is repositioned before or after the metal strip 2 is cut are explained in more detail below in connection with FIG. 2.
- the control device 50 can precisely coordinate the time at which the guide roller 11 is repositioned with the time at which the metal strip 2 is cut.
- the cutting device 40 can provide a signal or data that characterize the time of cutting.
- the control device 50 can also be set up to cause the cutting device 40 to cut the metal strip 2 at a predetermined time.
- the control device 50 can receive information about the thickness and/or transport speed of the metal strip 2 from the sensor unit 60.
- the sensor unit 60 is designed to measure the thickness and/or transport speed of the metal strip 2. Alternatively or additionally, 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 relative to a support roller 12, with which the guide roller 11 forms a guide roller pair, in relation 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 or downstream of the support roller 12 in relation to the transport direction 3. This is indicated by the vertical dashed line that runs perpendicular to the transport direction 3.
- the travel path d covered is preferably quite large compared to a thickness of the metal strip 2 of a few millimeters, so that the pair of guide rollers 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 path d can, for example, be approximately ten to one hundred times the strip thickness.
- a typical travel path 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 to 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 hit the side of the second guide element 24 instead of running along its surface.
- While a thin metal strip 2 with a thickness of less than 6-13 mm can thus be fed to the first reel via the first transport path 22 without any impairments, in particular without colliding with the guide shaft 21 or the second guide element 24, can be guided when the guide roller 11 is in the second roller position P2, this is not possible for thick metal strips 2 with a thickness of 6-13 mm or more. Such thick metal strips 2 can only be safely fed to the first reel via the first transport path 22 if the guide roller 11 is in the first roller position P1.
- the guide roller 11 can therefore only be positioned in the second roller position P2 when no more metal strip 2 is running 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 from which the guide roller 11 can be moved after the metal strip 2 has been cut 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 relative to a support roller 12 of the guide roller pair 10 in relation to a transport direction 3.
- a gap L is formed between a head end 4 of the subsequent metal strip section 2b and a foot end 5 of the preceding metal strip section 2a.
- the gap L can be further enlarged after the division, 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 in relation 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 only start repositioning the guide roller 11 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 being 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 method step S1 the metal strip 2 is guided to a first reel 20 using a guide roller pair 10.
- the metal strip 2 runs over a guide roller 11 of the guide roller pair 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 increased simultaneously or at least immediately after the metal strip 2 has been cut.
- a time window opens for the repositioning of the guide roller 11. Accordingly, in a further method step S4a, the guide roller 11 is moved into the second roller position - as indicated by the arrow.
- 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 on 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 and the first reel 20 can be prepared 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. After the guide roller 11 is positioned in the second roller position, the metal strip 2 can be divided 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.
- the subsequent metal strip section 2b is consequently fed to the second reel via the guide roller 11 on the second transport path 32.
- Whether the time window in which the guide roller pair 10 does not guide 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 following metal strip section 2b (on the first transport path 22) is transported.
- the transport speed of the following 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 set 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 increased slightly above the transport speed of the subsequent metal strip section 2b specified by the manufacturing process of the metal strip 2.
- the head end 4 of the subsequent metal strip section 2b consequently reaches the guide roller pair 10 before the guide roller 11 can be positioned in the second roller position.
- the test in method step S2 can be based on the thickness of the metal strip 2 and/or the transport speed.
- the decision in method 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 using a look-up table in which instructions are stored about the time of repositioning the guide roller 11 depending on the strip thickness and/or the transport speed.
