Definitions
- the invention relates to a method for producing a metallic strip in a continuous casting rolling process, in which first a slab is cast in a casting machine and fed to a downstream in the conveying direction of the strip finish rolling mill and rolled here. Furthermore, the invention relates to a device for carrying out the method.
- the present invention is accordingly used in cast-rolling plants which produce a finished strip from liquid metal in continuous operation.
- a strategy is proposed which can be used if an interruption of the rolling operation in the finishing mill takes place intentionally or unintentionally.
- Known casting mills convert liquid steel in a compact plant to hot strip. First, slabs of endless length are poured.
- slabs are cut by means of scissors, which correspond in their dimensions to a desired hot-rolled size.
- furnaces often designed as a roller hearth furnace, the slabs are conditioned in temperature. Subsequently, the slabs are individually fed to a rolling train and rolled. Subsequently, the strips are cooled in a cooling section and reeled. The leagues leave the rolling line for further processing.
- the slabs are cut so that two or more bundles can be produced from this slab.
- a flying scissors is additionally arranged, the cut the long hot strip so that the desired waist size is achieved. This process reduces the number of threading and unthreading processes that are critical to rolling, allowing thinner hot strips to be produced more safely.
- the helmsman or the automation system stops rolling in the event of a fault.
- the scaffolds are generally driven in the shortest possible time, all drives are stopped and the strand comes to a standstill. Since the slab is not divided up to the mold, there are cases where inevitably the casting machine comes to a standstill.
- This unit is particularly critical to see. If the standstill takes too long, the steel solidifies in the mold and can only be removed very expensive or only with damage to the mold. An uncontrolled raising of the mold and the strand guide would usually lead to a strand breakthrough, so that the liquid steel pours over the aggregate and causes considerable damage. In particular, the strand guide rollers are sensitive to thermal overload during prolonged standstill.
- EP 2 259 886 B1 proposes to introduce a cut into the strip, to bend the strip foot in the conveying direction upwards and to chop the following strip.
- this requires conceptually that the following strip material is still in motion.
- Further or similar solutions as well as special aspects of dividing the slab or strip are described in EP 0 625 383 B1, in DE 198 56 767 A1, in DE 42 20 424 A1, in JP 0122 4102 A, in US Pat JP 0527 7539 A, JP 6315 7750 A and JP 2001 276 910 A.
- the operation should not be interrupted as much as possible even during a planned roll change.
- the strand is separated, the severed band is rolled out. Subsequently, slices are cut from the strand and transported away by means of a discharge device as scrap.
- the scrap optionally stacked behind the shears can not necessarily be returned directly to the furnace.
- the scrap must then rather be divided in an intermediate step.
- the scissors can not chop backwards.
- no scrap chute is present.
- the invention is based on the object, the production line after the intended (for example due to a roll change) or unintentional occurrence of a production stoppage in the finishing mill safely, quickly and economically and preferably partially or fully automatically put back into the normal operating condition. From the mold and further from the casting machine escaping steel or the resulting slabs or cast from this tape should be as fast as possible be removed to minimize damage and downtime.
- the material removed from the plant ie the scrap
- the material removed from the plant ie the scrap
- the simplest possible further processing ie a melting
- the recycling of scrap is to be made possible in a simple manner.
- a compact design of the system is desired.
- the goal is also that in a simple way small pieces of scrap are generated, which can be remelted directly.
- the solution of this object by the invention is characterized in that in the case of a planned or unplanned production interruption in the finishing mill, the following steps are carried out: a) cutting the strip at a location between the casting machine and the finish rolling mill by means of a separating device; b) conveying the section of the strip following the cut in the conveying direction into a strip store by means of a driver, wherein the driver is arranged in the conveying direction behind the separating device; c) repeated cutting of the strip by means of the separating device and chopping the downstream part of the strip in the conveying direction by means of the separating device into parts, preferably with a defined longitudinal extent; d) chopping the stored strip section into parts, preferably with a defined longitudinal extent.
- step d) a return conveyance of the strip located in the strip accumulator counter to the conveying direction by means of the driver to the separator takes place where the Zerhherebyseln the stored band section takes place by means of the separator.
- the parts which are produced in steps c) and d) are preferably removed into a collecting space.
- step c) tape sections with a length in the conveying direction between 0.1 m and 5 m can be cut.
- the apparatus for producing a metallic strip in a continuous casting roll process comprising a casting machine and a finished rolling mill downstream in the conveying direction of the strip, is characterized according to the invention in that a separating device is arranged between the casting machine and the finish rolling mill and that following in the conveying direction of the separating device a tape storage is arranged for receiving a tape portion, wherein in the conveying direction behind the separating device and in front of the tape storage, a driver is arranged, which is designed for conveying the tape in the tape storage.
- the driver is also designed to convey the tape back to the separator.
- the separating device is preferably a drum shears. But it is also possible to use a pendulum scissors or a movable scissors.
- a collecting space for strip parts is preferably arranged below the separating device.
- a scrap chute may be arranged between the separating device and the collecting space.
- a further driver may be arranged in the conveying direction in front of the separating device. In the conveying direction in front of the separating device may continue to be arranged a furnace.
- the concept can be applied to all plant concepts with any combination of caster, roughing mill, furnace, intermediate mill and finishing mill.
- the invention provides that, in particular, a chopper scissors in combination with a tape storage is used.
- the strip arriving from the casting machine is temporarily stored in the strip store.
- a drum shears severed the tape.
- a driver behind the separator promotes the tape in the tape storage. This creates a short gap.
- the separating device divides the incoming strip into scrap pieces, which preferably slide over a scrap chute into a scrap disposal area.
- a separator behind the caster separates the strand.
- the remaining belt is accelerated and the separator (drum shears) parts it.
- the strand which is now being poured, is cut into plates with the separating device behind the casting machine and pushed off by means of a discharge device.
- the jam in the finishing train is removed, for example, it is disposed of manually.
- the strip between the finishing train and the separating device drum shears
- the strip between the finishing train and the separating device can then be moved backwards (ie against the conveying direction) from the tape storage by the separator and chopped by this.
- the scrap pieces can be remelted directly.
- the area between the drum shears and the finishing line can be cleared backwards.
- the proposed construction is compact and can save energy.
- the tape storage can also be used as Zugreglung.
- a drum shears can dispose of the scrap quickly and efficiently.
- Fig. 1 shows schematically a casting-rolling plant for the production of a steel strip and an enlarged view of a separator in the form of a pair of scissors, which is arranged between the casters and the finishing mill of the plant.
- FIG. 1 an example of a casting-rolling plant is outlined, which is designed as a full-Konti- system and which includes a casting machine 2 and a finish rolling mill 3 as central elements.
- a roughing mill 12 is provided, to which - depending on the system concept - an oven 1 1 (connecting roller table with heating function) is connected.
- Behind the furnace 1 1 follows the finish rolling mill 3.
- Behind the finish rolling mill 3 is a cooling section 13 and a separator in the form of a flying shears 14.
- At least one reel 15 and 16 follows.
- a separator in the form of a pair of scissors 17 for the band 1 is arranged.
- FIG. 1 Another pair of scissors 5 (separator) is located between the furnace 1 1 and the finished mill 3 at a point 4. Finally, the other scissors (separator) 14 behind the cooling section 13 and in front of the reels 15, 16 is arranged. In Fig. 1 is still a pair of scissors (separator) 17 can be seen, which is located behind the casting machine 2 and the furnace 1 1.
- a tape storage 6 is arranged, which is indicated only schematically.
- the tape 1, which comes out of the oven 1 1, is funded by a driver 10.
- the band 1 can be cut or cut through.
- a further driver 7 the separated tape 1 can then be conveyed into the tape storage 6.
- the strip 1 is cut through at the point 4 by the separating device 5. There is then a conveying of the part of the belt 1, which is located in the conveying direction F behind the separating device 5, in the tape storage 6, for which the driver 7 is used. After again cutting through or cutting through the strip 1 by means of the separating device 5, a chopping of the strip section can then be carried out, which follows from the casting machine 2.
- the strip is cut into parts, preferably of a defined length, in a manner known per se (see EP 2 259 886 B1 for this purpose) and removed via a scrap chute 9 into a collecting space 8.
- the band 1 located in the band memory 6 is counter to the conveying direction F by means of the driver 7 to the separator 5 fed back, hacked by the separator 5 and equally discharged into the plenum 8.
- the proposed method can also be used in a deviating plant concept of a casting-rolling plant.
