Definitions
- Coiler system for a combined casting and rolling plant and method for operating the coiler system
- the invention relates to a reel system according to claim 1 and a method for operating the reel system according to claim 10.
- An improved coiling system for a combined casting and rolling plant for coiling a thin-walled sheet can be provided in that the coiling system has at least a first mandrel, a first coil device, a first strip feed, a second strip feed, a strip storage and a drive device.
- the first mandrel extends along a winding axis.
- the drive device has a component carrier and a drive motor which is connected to the component carrier.
- the first coil device and the second strip feed are fastened to the component carrier and the drive motor is designed to rotate the component carrier, the first coil device and the second strip feed about the first winding axis.
- the strip storage is arranged radially outside the component carrier and the first coil device.
- the first strip feed is radially outside the strip storage. arranged.
- the finished rolled strip can be fed into the coiler system along a conveying direction of the finished rolled strip via the first strip feed.
- the first strip feed is designed to transport the finished rolled strip to the strip storage.
- the strip storage is designed to wind the finished rolled strip fed via the first strip feed into an intermediate ring.
- the second strip feed is designed to unwind the finished rolled strip wound into the intermediate ring radially on the inside of the intermediate ring and to feed it to the first coiling device.
- the first coiling device is designed to wind the finished rolled strip onto the first mandrel into a coil.
- This design has the advantage that a reel speed with which the first coil device reels the finished rolled strip into the coil is independent of a first strip speed of the finished rolled strip with which the finished rolled strip is transported in the first strip feed.
- This also has the advantage that the finished rolled strip can be designed to be particularly thin-walled and can be transported out of the finishing rolling mill at a high first strip speed.
- the reel system can also reel in a high-speed finished rolled strip, so that the combined casting-rolling plant has a particularly high throughput.
- the first strip feed can be pivoted about a second pivot axis between a start-up position and a conveying position.
- the second pivot axis is aligned parallel to the central axis.
- the first strip feed is designed to convey the finished rolled strip along a straight line.
- the second strip feed is designed to guide the finished rolled strip radially inwards along a second straight line in the direction of the first coiling device.
- the first strip feed and the second strip feed are aligned in alignment with one another so that the first straight line and the second straight line are arranged to overlap.
- the first strip feed is pivoted relative to the start-up position such that the first straight line is aligned tangentially to the winding axis.
- the first strip storage device has at least one first roller arrangement with several support rollers arranged offset in the circumferential direction around the winding axis.
- the support rollers are arranged on a first circular path around the winding axis.
- the support rollers roll on the finished rolled strip.
- the strip storage device is designed formed to wind the finished rolled strip on a second circular path around the winding axis to the intermediate ring while guiding it along the support rollers.
- the strip storage device has a carrier unit with at least a first carrier, a carrier joint and a second carrier.
- the carrier joint connects the first carrier to the second carrier.
- the second carrier can be pivoted relative to the first carrier between a first position and a second position.
- a first partial arrangement of the first roller arrangement is arranged on the first carrier and a second partial arrangement of the first roller arrangement is arranged on the second carrier.
- the first carrier and the second carrier delimit an annular gap on the outside in which the intermediate ring can be arranged.
- the second carrier is pivoted away from the first carrier.
- first carrier and/or the second carrier are partially ring-shaped.
- the first carrier and/or the second carrier are arranged in the first position on a common third circular path.
- the first carrier encloses an angle of approximately 160° to 180° inclusive.
- the second carrier encloses a second angle of approximately 160° to 180° inclusive.
- the strip storage device has a carrier unit with at least a first carrier and an adjusting device, wherein the adjusting device connects the support roller to the first carrier.
- the adjusting device is designed to move the support roller between a first radial position and a second radial position arranged radially outside of the first radial position. This ensures that the intermediate ring can be designed in multiple layers, wherein preferably in each layer that is on the intermediate ring is wound up from the outside, the adjusting device moves the support roller radially outwards in order to provide sufficient installation space for the increasing thickness of the intermediate ring.
- the reel system has at least one second separating device, in particular a shear.
- the separating device is arranged radially between the first coiling device and the second strip feed.
- the second separating device is attached to the component carrier.
- the second separating device is designed to separate the finished rolled strip. This design has the advantage that the finished rolled strip is separated shortly before coiling when the coil is full.
- the strip storage device has a first input roller, wherein the finished rolled strip can be introduced into the strip storage device from the first strip feed at the first input roller.
- the first input roller is designed to deflect the finished rolled strip in its conveying direction.
- the first input roller has a first magnetic device which is designed to hold the finished rolled strip at the first input roller by means of a first magnetic connection.
- This design has the advantage that an annular design of the intermediate ring in the strip storage device is ensured. Furthermore, an unwanted lifting of the finished rolled strip on the input side of the strip storage device is avoided by the first magnetic connection.
- the second strip feed has a second input roller, wherein the second input roller is arranged on the input side in relation to the conveying direction of the finished rolled strip on the second strip guide.
- the second input roller is designed to deflect the finished rolled strip in its conveying direction from the strip storage in the direction of the first coil device.
- the second input roller has a second magnetic device, wherein the second magnetic device is designed to hold the finished rolled strip on the second input roller by means of a second magnetic connection.
- an improved method preferably for operating a coiling system described above, can be provided by feeding a finished rolled strip into the coiling system via a first strip feed of the coiling system, the first strip feed transporting the finished rolled strip to a strip storage device of the coiling system, the strip storage device winding the finished rolled strip into an intermediate ring which extends about a winding axis, a second strip feed unwinding the finished rolled strip from the intermediate ring on a side opposite the first strip feed in the radial direction and guiding it towards a first coiling device of the coiling system, the first coiling device winding the finished rolled strip into a coil.
- This design has the advantage that the winding speed at which the finished rolled strip is wound onto the first mandrel by the strip storage is essentially independent of the first strip speed at which the finished rolled strip is fed into the coiler system. This means that the fully wound coil can also be removed from the coiler system and the finished rolled strip can continue to be stored in the strip storage without interrupting production or the delivery of the finished rolled strip from the combined casting and rolling plant.
- the finished rolled strip is guided from the first strip feeder to the intermediate ring from the radial outside and the strip storage winds the finished rolled strip onto the intermediate ring from the radial outside, relative to the winding axis.
- This design has the advantage that the intermediate ring can be arranged in the radial direction between the first strip feeder and the second strip feeder and the installation space required for the strip storage is therefore particularly small.
- the first coil device and the first strip feed are rotated around the winding axis when the finished rolled strip is being coiled on the first mandrel.
- This design has the advantage that the coiling system can also be designed with high masses and the coiling process does not have to be interrupted while the component carrier is accelerated by the drive motor together with the first coil device of the second strip feed to a first circumferential speed of the intermediate ring.
- the finished coil is removed from the first mandrel while at the same time the finished rolled strip is wound up into the intermediate ring
- the finished rolled strip wound into the intermediate ring rotates around the winding axis in the strip storage at a first circumferential speed.
- a second circumferential speed of the component carrier of the first coil device and the second strip guide around the winding axis is different from the first circumferential speed in order to wind up the finished rolled strip. It is particularly advantageous here if the first circumferential speed runs in an opposite direction to the second circumferential speed, whereby the finished rolled strip can be wound up at a particularly high strip speed and at the same time the intermediate ring can be reduced in size so that there is sufficient storage capacity when the intermediate ring grows again due to the finished rolled strip while the finished rolled coil is to be removed.
- the first strip feed is pivoted into the start position, the second strip feed and the first strip feed being aligned with one another in such a way that the first straight line and the second straight line are arranged so as to overlap.
- the finished rolled strip is guided via the first strip feed and the second strip feed to the first coil device and a start of the coil is wound.
- the first strip feed is pivoted into the conveying position and the drive motor is activated so that the second strip feed and the first strip feed and the first coil device rotate about the winding axis.

- the finished rolled strip 80 is conveyed tangentially into the strip storage 110, for example at a first strip speed v1 via the roller conveyor 130 and the first strip feed along the first straight line 285.
- the finished rolled strip 80 is guided through the first input roller 215 into the annular gap 250.
- the finished rolled strip 80 preferably comprises steel and has been cooled by the cooling line 40 to below a Curie temperature, the finished rolled strip 80 has ferromagnetic properties.
- the first magnet arrangement 220 forms a first magnetic connection with the finished rolled strip 80, so that the finished rolled strip 80 reliably rests against the first input rolling surface of the first input roller 215.
- the first strip speed v1 of the finished rolled strip 80 is preferably 10 m/s up to and including 50 m/s. It is particularly advantageous if the first strip speed v1 of the finished rolled strip 80 is at least 20 m/s up to and including 50 m/s.
- the second magnet arrangement of the second input roller 230 creates a second magnetic connection with the ferromagnetic material of the finished rolled strip 80 (see FIG. 11).
- the finished rolled strip 80 lies well against the second input rolling surface 245.
- the second input roller 235 deflects the finished rolled strip 80 by approximately 90°.
- the finished rolled strip 80 lying in the annular gap 250 is guided radially inwards through the second strip feed 105 in the direction of the first mandrel 90.

- the finished rolled strip 80 is introduced into the strip storage 110 via the first strip feed 100 tangentially to the winding axis 140 and to the first roller arrangement 155. Due to the small second thickness d2 of the finished rolled strip 80, the finished rolled strip 80 is also particularly flexible and bendable.
- the high first strip speed v1 of the finished The centrifugal force FZ acting on the finished rolled strip 80 causes the finished rolled strip 80 to be pressed radially outwards in the strip storage 110 due to a centrifugal force FZ acting on the finished rolled strip 80 (cf. FIG. 10A).
- the finished rolled strip 80 is guided along the first roller arrangement 155 at a first circumferential speed co 1.
- the finished rolled strip 80 rests on the support rollers 210 of the first roller arrangement 155.

- the first mandrel 90 winds the finished rolled strip 80 into a coil 85.
- the first mandrel 90 is driven for this purpose.
- a second strip speed v2 at which the finished rolled strip 80 is wound up essentially corresponds to the first strip speed v1.
- a first graph 320 is shown in FIG 10B and a second graph 325 is shown in FIG 10C. It can be clearly seen (see FIG 10B) that with increasing time t, the maximum possible second strip speed v2MAX, with which the finished rolled strip 80 can be wound through the first mandrel 90 and the first coil device 95, increases due to the increasing coil diameter.
- the maximum possible second strip speed v2MAX depends on the coil diameter, the second thickness d2 of the thin finished rolled strip 80 and a maximum possible rotational speed of the first mandrel 90.
- the second graph 325 in FIG. 10C is divided into a first to seventh graph section 330 to 360, which correlate with individual method steps described below.
- the first method step 505 the second belt speed v2 is essentially constant (cf. first graph section 330).
- a second method step 510 a coil thickness of the already wound coil is monitored. If the coil 95 reaches a predefined coil thickness, the process continues with a third method step 515.
- the drive motor 145 is started and the component carrier 150 is accelerated in the circumferential direction about the rotation axis 140 to the second circumferential speed co2.
- the first circumferential speed co 1 and the second circumferential speed c 2 have the same direction of rotation.
- the drive motor 145 accelerates the component carrier 150 to such an extent that the first circumferential speed co 1 and the second circumferential speed co2 are essentially identical.
- This third method step 515 is started when a coil thickness of the coil 95 has reached a predefined coil thickness and the coil 95 must be pulled off the mandrel 90.
- the finished rolled strip 80 is wound into an intermediate ring 305 in the strip storage 110 by the second input roller 235 and the first roller arrangement 155.
- the finished rolled strip 80 is wound onto the intermediate ring 305 via the first input roller 215 on a rolling surface 240, which is formed from the inner generatrices of all support rollers 210, so that an outer diameter of the intermediate ring 305 increases with each layer of the finished rolled strip 80 on the intermediate ring 305.
- the intermediate ring 305 rotates in the strip storage 110 at the first circumferential speed co 1 around the winding axis 140.
- the second strip speed v2 with which the finished rolled strip 80 is coiled decreases (cf. second graph section 335, FIG 10C).

- the strip speed v1 of the finished rolled strip 80 with which the finished rolled strip 80 is fed into the coiler system 45 is essentially constant.
- the first circumferential speed co 1 and the second circumferential speed c 2 are essentially identical at the end of the fourth method step 520, so that the intermediate ring 305 is no longer unwound by the second input roller 235 and the second strip speed v2 of the finished rolled strip 80 is reduced to zero at the separating device 161 (see third graph section 340, FIG 10C).
- the drive motor 145 is controlled in such a way that the second circumferential speed c 2 is equal to the first circumferential speed co 1 when the coil 95 is completely wound and full.
- a fourth method step 520 which is carried out at the same time as the third method step, the adjusting device 225 is activated while the intermediate ring 305 is being wound up. While the intermediate ring 305 is being wound up, an outer diameter of the intermediate ring 305 increases with each layer of the finished rolled strip 80 wound onto the intermediate ring 305.
- the adjusting device 225 and the adjusting unit 230 provided for each support roller 210 and the input roller 215 move the respectively assigned support roller 210 and the first input roller 215 from the first radial position radially outwards in the direction of the second radial position. This process is carried out as long as finished rolled strip 80 is being wound onto the intermediate ring 205.
- the second separating device 161 is actuated, while the finished rolled strip 80 is at the second separating device 161.
- the first mandrel 90 can be driven further in order to be able to wind up the severed finished rolled strip 80.
- One strip end of the finished rolled strip 80 is held by the second strip feed 105.

- the component carrier 150 and the second strip guide 105 arranged on the component carrier 150, the separating device 161 and the first coil device 95 continue to rotate at the second peripheral speed. speed o2, which is identical to the first circumferential speed co 1.
- the finished rolled strip 80 which continues to come from the cooling line 55, is wound onto the outside of the intermediate ring 305.
- a seventh process step 535 following the sixth process step 530 the separating device 161 is opened.
- the drive motor 145 is controlled in such a way that the second circumferential speed c 2 is reduced compared to the first circumferential speed co 1.
- This causes the finished rolled strip 80 to be slowly unwound from the inside from the intermediate ring 305.
- the unwound finished rolled strip 80 is introduced into the first coiling device 95 by the separating device 161 and wound onto the first mandrel 90 to form the other coil 85.
- the first mandrel 90 is set in motion again.
- the winding of a new coil 80 begins (see fourth graph section 345, FIG 10C).
- the component carrier 150 is not only braked, as in the seventh method step 535, but the direction of rotation of the component carrier 155 is changed in a direction opposite to the direction of rotation of the intermediate ring 305 (see FIG. 15).
- the individual layers of the intermediate ring can be unwound from the inside.
- the unwound layers are transported via the second strip feed 105 to the first coil device 95 and wound onto the further coil 85.
- the strip speed v2 in the first coil device can be increased to 50 m/s, which is significantly greater than the first strip speed v1 of the finished rolled strip 80 at the first strip feed 100 (see fourth and fifth graph sections 345, 350, FIG. 10C).
- the eighth method step 535 is carried out until the layers of the intermediate ring 305 have been unwound and the intermediate ring 305 is only present in one layer in the strip storage 110.
- the component carrier 150 is braked to a standstill.
- the second strip speed v2 is also reduced to the first strip speed v1 (see sixth graph section 355, FIG 10C).
- the drive motor 145 is controlled such that the component carrier 150 assumes the coil position.
- the finished rolled strip is coiled at the second strip speed v2, which corresponds to the first strip speed v1 (see seventh graph section 360).
- the process continues with a ninth method step 545.
- the actuating device 225 is activated such that the actuating units 230, the support rollers 210 and the first input roller 215 are moved from the second radial position radially outward in the direction of the first radial position, radially inward in the direction of the winding axis 140.
- the first method step 505 can be continued.
- the method described in FIG. 9 can be carried out until sufficient finished rolled strip 80 with the second thickness d2 has been produced and there is no further need for thin-walled finished rolled strip 80.
- no further coiling with the second coiling device 125 or third coiling device 126 is necessary.
- FIG 18 shows a flow chart of a changeover process for changing from the thin finished rolled strip with the second thickness d2 to the finished rolled strip 80 with the first thickness d1.
- a first changeover step 605 the component carrier 150 is moved into the coil position (see FIGS. 10A, 17) so that, for example, the second strip feed 105 is arranged between the first mandrel 90 and the first carrier 165. This ensures that an overhead run of the finished rolled strip 80 on the underside of the second carrier 170 is avoided.
- a second changeover step 610 the tape storage device 110 is opened by moving the second carrier 170 from the first position to the second position (see FIG 6).
- the first tape feed 100 is pivoted from the conveying position into the starting position about the second pivot axis 280. Furthermore, the component carrier 150 is rotated by the drive motor 145 about the winding axis in such a way that the first tape feed 100 and the second tape feed 105 are aligned (see FIG. 7).
- the second thickness d2 of the finished rolled strip 80 is increased from the second thickness d2 to the first thickness d1 in the finishing rolling train 35.
- the first separating device 41 separates the finished rolled strip 80 before the finished rolled strip 80 with the first thickness passes through the first separating device 41.
- the separated finished rolled strip 80 is wound onto a residual coil (not shown) by the first mandrel 90 and the first coiling device 95. After the remaining finished rolled strip 80 has been wound, the winding by means of the first mandrel 90 and the first coiling device 95 is completed.
- a sixth changeover step 630 the discharge device 130 is set such that the finished rolled strip 80 with the first thickness d1 is conveyed in the direction of the second coiling device 125 or the third coiling device 126, so that either the second coiling device 125 or the third coiling device 126 can alternately coil the finished rolled strip 80 with the first thickness d1.
- the first thickness d1 can be approximately 1 mm to 25 mm.
- the coils wound on the second coil device 125 or third coil device 126 are removed.
- FIG 19 shows a detail of a perspective view of a reel system 45 according to a second embodiment.
- the reel system 45 is essentially identical to the reel system 45 according to the first embodiment shown in FIGS. 1 to 4, 6 to 8, 10 to 17. In the following, only the differences between the reel system 45 according to the second embodiment shown in FIG. 19 and the reel system 45 according to the first embodiment will be discussed.
- the second carrier 170 as used in the reel system 45 according to the first embodiment is dispensed with. Furthermore, the carrier joint 175 for coupling the second carrier 170 to the first carrier 165 is dispensed with.
- the methods for operating the reel system of the first embodiment shown in Figures 1 to 4, 6 to 8, 10 to 17, 19 can also be applied to the reel system 45 according to the second embodiment shown in Figure 19.
- the finished rolled strip 80 when it is wound into the intermediate ring 305, rests exclusively on the first roller arrangement 145, which is arranged on the first carrier 165.
- the finished rolled strip 80 or the intermediate ring 305 is guided freely and without support. This is possible because the finished rolled strip 80 is formed by the first carrier 165 and the first roller arrangement 155 arranged on the first carrier 165.
- the further rotation of the intermediate ring 305 at the first peripheral speed co1 further forms the preform, so that essentially a circular ring-shaped intermediate ring is formed even without support from the second carrier 170 and the first roller arrangement arranged on the second carrier 170.
- FIG. 19 thus has the advantage that the method described in FIG. 5 is simplified in that the second preparation step 410 and the eighth preparation step 440 can be dispensed with. Likewise, the third changeover step 615 can be dispensed with in the method described in FIG. 18.
- the coiler system 45 described in FIG. 19 is simpler and more cost-effective than the coiler system 45 according to the first embodiment. Furthermore, the operating methods according to FIGS. 5 and 18 for changing from the finished rolled strip to the finished rolled strip with the first thickness are simpler and easier to control.
- the designs of the coiler system 45 shown in the figures are particularly suitable for the production of the finished rolled strip 80 in the form of a continuous strand. This ensures that the thin-walled finished rolled strip can be safely coiled at a high first strip speed v1.
- the finished rolled strip 80 with the second thickness d2 can be particularly thin.
- a carousel coiler system can be dispensed with, which is far more complicated than the structure of the coiler system 45 shown in the figures.
- the finishing rolling mill 35 is completely independent of the coiler system 45 in terms of control.
- a particularly high coil speed for winding up the coil 85 can be achieved with the coiler system 45 shown in the figures. This means that the continuous casting machine can be fed with a particularly large amount of metallic melt and a large amount of thin finished rolled strip 80 can be produced without the casting speed in the continuous casting machine 15 having to be reduced.
