Definitions
- the present invention relates to a method and an apparatus for the rapid removal of metallic plate from heavy plate from a rolling mill.
- a plate made of heavy plate hereinafter referred to as a plate, is to be understood as meaning a metallic plate having a thickness between 8 and 250 mm, a width of> 900 mm and a length> 3 m (see Document 570, "Heavy plate production and Application ", Steel Information Center Düsseldorf, 1st edition 2001).
- the invention relates to a method for decorating metallic plates, preferably of steel, from a rolling mill, preferably a hot rolling mill or a cast-rolled composite plant.
- the invention relates to an apparatus for the rapid removal of steel plates from a hot rolling mill.
- a slab strand is produced continuously (ie endlessly) in a continuous casting plant of a cast-rolled composite plant.
- the endless slab strand itself or a slab cut therefrom is then subjected to high-reduction forming in at least one rolling stand of a rough rolling mill.
- the pre-rolled slab strand also called pre-strip
- the pre-rolled slab is heated in a reheating furnace and descaled in a descaling device.
- steel strips are subsequently cooled to the required temperature in a cooling zone and subsequently wound up alternately in at least two coiler devices to form steel coils (reels or coils). If necessary, the steel strip is divided into suitable lengths before winding.
- hot strip can be produced in thicknesses of 0.6 mm to 25 mm and in certain circumstances also up to 30 mm (in the case of narrow widths and materials of low strength).
- Plates (so-called thin sheets with thicknesses less than 3 mm or heavy plates with thicknesses of 3 mm to 25 mm, optionally up to 30 mm) are processed.
- EP 1909979 Bl is a casting-rolling composite system for
- the slab produced in the continuous casting process is subjected to liquid core reduction (LCR) in the continuous casting machine; Subsequently, a reduction of the slab takes place in one or more rolling mills of a rolling train. Thereafter, the cooling and the transverse distribution of the strand to the desired plate length.
- LCR liquid core reduction
- Plates can also be produced or further processed on a cutting device (cut-to-length line).
- the coils wound on the reel are unwound, straightened, transversely divided, processed into boards and stacked. In these devices, however, only plates with a thickness of up to about 16 mm can be produced.
- WO 2009/121678 AI a discharge device for a casting-rolling composite system is described, which allows in an emergency, the continuation of the continuous casting of the casting-rolling compound.
- cut pre-product sections with a length of 8 to 14 m are removed from the plant.
- By accelerating the cut precursor sections sufficiently long gaps can be formed between the individual sections, so that collisions between the sections are avoided.
- the speeds of these precursors are still relatively small in order to transport the precursor sections out of the plant.
- An object of this invention is to provide a method and apparatus for removing slabs from a cast-roll compound plant, wherein even relatively short slabs (eg, 3 to 8 meters in length) are safely removed from the plant at high speed and with low cycle times can be removed and stored.
- a further object of this invention is to broaden the product range of a cast-rolled composite plant by also producing plates of different thickness and length in addition to the above-described possibility of producing steel coils on the cast-rolled composite plant.
- the system parameters such as the number of rolling mills in operation and their reduction rates, can be adjusted so that inline (ie in the casting-rolling compound system itself) plates with thicknesses of at least 8 mm to 25 mm, preferably 40 mm, widths from 900 mm to 2100 mm, and lengths from 3 m to 18 m can be produced.
- inline ie in the casting-rolling compound system itself
- widths from 900 mm to 2100 mm preferably 3 mm to 18 m
- other grades should also be produced.
- the material produced for example, in continuous, continuous operation, should be able to be divided transversely at a suitable point. Subsequently, the plates are to be discharged from the system and stored with a predetermined length, so that the subsequent material can be freely produced further. It would be desirable if the Ausschleuse- and storage device could be easily and quickly changed to different plate lengths.
- the first plate After dividing a, e.g. endlessly produced strand of a hot strip, whereby a first plate is separated from the strand of indeterminate length, the first plate is transported on the roller table in the transport direction.
- the first plate is preferably accelerated in the transport direction, so that a gap between the strand and the first plate is formed.
- roller table has reached a predefined position, the first plate is placed on the roller table. Subsequently, a second plate is separated from the strand and the second plate is transported on the roller table in the transport direction. After the second plate has reached a predefined position on the roller table, the second plate is placed in the transport direction in front of the first plate on the roller table. As a result, at least two plates are placed in a row (in-line) on the roller table. Subsequently, the first and the second plate are discharged from the roller table in a tray, wherein the discharge preferably takes place transversely to the transport direction. Alternatively, however, the plates may also be conveyed in a vertical direction (e.g., above or below the roller table). The conveying transverse to the transport direction is also referred to as cross-conveying; the facility for this is called cross conveyor.
- a combination is also conceivable, e.g. that several cross conveyors in each case a plurality of plates (eg. 2 transverse conveyors each 2 plates) auschedn.
- Roller table is stored. Subsequently, the first, second and third plates are discharged simultaneously. This either further reduces the minimum plate length for a given cycle time or increases the cycle time for a given plate length.
- a cross conveyor When feeding out, it is expedient if a cross conveyor performs the following steps:
- the discharge can also be carried out by the following method steps:
- the stacking of several plates on a shelf is particularly simple when the shelf is lowered after laying down the at least one plate by at least the plate thickness.
- the plates are separated from a strip / strand by transverse cutting before being transported on the roller table in the transport direction.
- the object mentioned at the outset is likewise achieved by a device for rapid removal of steel plates from a hot rolling mill, comprising
- a roller table for transporting a plate in the transport direction wherein the roller table has a plurality of driven rollers for accelerating the plate in the transport direction;
- a cross conveyor for simultaneously discharging a plurality of plates from the roller table in a tray or more cross conveyor for synchronous Ausördern of at least one plate transversely to the transport direction of the roller table in a tray.
- the delivery device with a plurality of transverse conveyors for the synchronous discharge of at least one plate each comprises a synchronization device (eg an operative connection between the control devices (see “electric wave") of the transverse conveyors, or a mechanical connection between the cross conveyors) for synchronizing the Cross conveyor.
- a synchronization device eg an operative connection between the control devices (see “electric wave") of the transverse conveyors, or a mechanical connection between the cross conveyors
- the means for depositing the plate on the roller table comprises a stop and preferably an actuator (for example a hydraulic, pneumatic or electric actuator) for driving in and out of the stop in the transport path of the plate on the roller table ,
- the means for depositing is as a braked
- Roller table roller formed.
- roller table comprises several - arranged in the transport direction one behind the other - means for storing.
- a simple transverse conveyor has a lifting rail, a lifting actuator for lifting the lifting rail, a traveling carriage for moving the plate transversely to the transport direction, and a moving actuator for moving the traveling carriage on the lifting rail.
- the lifting rail has a plurality of arms, wherein in the starting position between two arms at least one roller table roller is arranged.
- the starting position is understood to be any position which the transverse conveyor assumes transversely to the transport direction immediately before the plates are conveyed out.
- Another simple transverse conveyor has a gripper for clamping a plate and a pivoting unit for pivoting the plate about an axis of rotation aligned in the direction of transport.
- a simple shelf is formed by a height-adjustable storage table with an actuator for height adjustment of the storage table. Since the plate is preferably cut into the cooler after the last stand of the finishing train and before the plate enters the plate, and the plate is accelerated after being cut on the roller table to create a gap between the continuously produced hot strip and the plate the plates have a variable transport speed depending on the time course of the acceleration. However, in order to achieve a uniform cooling of the plate even in this case, it is advantageous if, during the cooling of a plate in the cooling section, the cooling section
- At least one detector for determining the speed of the plate in the cooling section
- the corresponding cooling section comprises
- At least one detector for determining the speed of the plate in the cooling section
- An adjusting device for adjusting the amount of coolant through the cooling nozzle An adjusting device for adjusting the amount of coolant through the cooling nozzle.
- the adjusting device can be designed, for example, as a control or regulating device.
- the target amount of coolant is calculated as a function of the speed and controlled the actual amount of coolant set such that the difference between the desired and the actual coolant amount is minimized.
- the speed is detected several times during the passage of the plate through the cooling section and the cooling section has a plurality of cooling zones (with at least one cooling nozzle each).
- the cooling of the plate can be set very accurately even with transient speed or acceleration curves.
- the determination of the speed in a section may e.g. be done by position detectors that determine the transit time of the plate between two positions and thus the speed can be easily determined by the knowledge of the distance between two detectors.
- the speed may be determined differently, e.g. by measuring the speed of the roller table rollers, by laser Doppler anemometry etc.

- the still endless finished strip 18 is transversely divided by a pair of scissors 8 in plate lengths of 3 m to 18 m.
- the scissors 8 are arranged directly behind the last stand 7 d of the finishing train 7.
- the scissors 8 could also be arranged upstream of the finishing train 7 or even behind the cooling section 10.
- An arrangement of the scissors 8 immediately after the finishing train 7, however, is advantageous because, compared to the arrangement of the scissors 8 in front of the finishing train 7, the head of the cut hot strip does not have to be threaded into the rolling stands 7a... 7d of the finishing train 7 after each cut ,
- the arrangement shown is also advantageous over an arrangement of the scissors 8 after the cooling section 10, since the cutting forces due to the higher temperature of the hot strip after the finishing train 7 are substantially lower.
- the plate is accelerated on the roller table 9 by a plurality of driven roller table rollers 9a in the transporting direction T in order to produce the largest possible gap between the finished strip 18 and the plate.
- This gap is determined by the length of the plate, the acceleration of the plate and the acceleration time.
- the sequence time tsequ also called cycle time
- the cross conveyor if at the same time n plates are discharged.
- the plate After cutting, the plate is cooled in a cooling section 10.
- the variable speed of the plate is taken into account due to the dynamic control of the cooling rates.
- To the position of the head of the plate within the cooling path is tracked. This ensures, on the one hand, a uniform surface temperature of the plate (including the plate head and foot).
- the tracking of the plate within the cooling section can, for example, by several inductive detectors below or above the roller table, which register the passage of a plate.
- the several, arranged in the transport direction and independently adjustable cooling nozzles adjusted so that all longitudinal sections of the plate are charged with the same amount of water.
- the plates produced are transported to the discharge device 14 by means of the roller table 13 and via the reels IIa, IIb.
- the tape catcher - in Fig lb is a so-called.
- Fang basket 12 is shown, which can be opened by an electric or hydraulic actuator (the unfolded position is shown in broken lines) - unfolded, raised or twisted. As a result, the transport path of the plates on the roller table 13 to the discharge device 14 is released.
- Bunden on the ESP system prevents the tape catcher 12 that the finished strip 18 reaches the discharge device 14.
- Discharge device 14 transported. In this area, for presetting the plate position transversely to the transport direction T, it is possible to provide so-called adjustable side guides, which can be adapted hydraulically or electromechanically to the plate width. In addition, a leveler can be arranged in this area to compensate for possible bends or bends of the plates.
- the discharge device 14 is designed in such a way that the strand continuously cast continuously by the continuous casting machine 1 or the finish strip 18 continuously hot-rolled in the finishing train 7 can be delivered unhindered, discharged from the hot rolling mill and stacked without the continuous operation of the casting rolling mill. Compound system disturbed or the production speed is affected.
