Abstract

The invention relates to a method and an apparatus for handling slabs (2a, 2b), produced in particular by continuous casting, the surfaces of which are ground before they are rolled in a rolling train, wherein the slab, lying on a reversible grinding table (12a, 12b), is moved back and forth under a grinding unit, arranged in a machining cell, of a grinding machine unit (I, II), the grinding table is moved linearly out of the machining cell after the grinding operation has been performed on one surface, the slab is lifted off the grinding table and fed to a turning device, wherein, after turning, the slab is removed from the turning device and, with an unworked, other surface lying uppermost, is brought onto the grinding table, which is then introduced once again into the machining cell for the working of this surface. One aim of the invention is to provide a considerably simpler method and apparatus for handling continuously cast slabs during the grinding thereof, said apparatus having at the same time a much simpler construction. This is achieved by the slab being taken up by a slab manipulator (9), which has a rotatable slab clamping and lifting means (14; 14a, 14b) and with which the clamped slab can be both transported transversely and turned.

Description

Verfahren und Vorrichtung zum Handhaben von Brammen zum Schleifen der Brammen-Oberflächen  Method and device for handling slabs for grinding slab surfaces
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Handhaben von Brammen, insbesondere hergestellt durch Stranggießen, deren Oberflächen vor dem Walzen in einer Walzstraße geschliffen werden, wobei die Bramme auf einem reversierenden Schleiftisch liegend unter einem in einer Schleifkabine angeordneten Schleifaggregat einer Schleifmaschineneinheit hin und her bewegt wird, der Schleiftisch nach der Schleifbearbeitung einer Oberfläche linear aus der Schleifkabine herausgefahren, die Bramme von dem Schleiftisch abgehoben und einer Wendeeinrichtung zugeführt wird, wobei die Bramme nach dem Wenden aus der Wendeeinrichtung entnommen und mit der unbearbeiteten, anderen Oberfläche obenliegend auf den Schleiftisch verbracht wird, der dann zur Bearbeitung dieser Oberfläche erneut in die Schleifkabine einfährt. The invention relates to a method and an apparatus for handling slabs, in particular produced by continuous casting, the surfaces of which are ground in a rolling train before being rolled, the slab being reciprocated on a reversing grinding table under a grinding unit of a grinding machine unit arranged in a grinding booth is, the grinding table after grinding a surface linearly moved out of the grinding booth, the slab lifted from the grinding table and a turning device is fed, the slab is removed after turning from the turning device and spent with the unprocessed, other surface overhead on the grinding table , which then re-enters the grinding booth for processing this surface.
Es ist in der Praxis üblich, dass insbesondere die breitseitigen und optional auch die schmalseitigen Oberflächen von stranggegossenen, aus dem Strang auf eine gewünschte Länge herausgetrennten Brammen vor dem Walzen in einer Walzstraße gemäß den vorstehend aufgezeigten Verfahrensschritten geschliffen werden. It is common in practice that, in particular, the wide-side and optionally also the narrow-side surfaces of continuously cast sliced out of the strand to a desired length slabs are ground prior to rolling in a rolling mill in accordance with the method steps outlined above.
Die dazu in Betrieb eingesetzten Einrichtungen erfordern zum Transport und Wenden der Brammen zahlreiche mechanische Bauteile und einen großen Hydraulikaufwand, insbesondere zusätzlich zu den Wendeeinrichtungen noch Transportmittel, die das Stranggussprodukt aufnehmen und der nächstfolgenden Bearbeitungsstation zuführen bzw. die den Matehalfluss aufrechterhalten. Denn auf Schienen verfahrbare Quertransport- bzw. Unterfahrwagen müssen zunächst auf den Schleiftisch gefahren werden, wozu dieser ebenfalls mit Fahrschienen versehen werden muss, wodurch sich eine schwere Ausführung ergibt, um die mit Hydraulikstützen angehobene Bramme von dem Schleiftisch abnehmen zu können. Die mehreren, parallel nebeneinander jeweils auf gesonderten Fahrschienen laufenden Quertransportwagen transportieren die übernommene Bramme dann zu einer stationären Brammenwendevorrichtung, z.B. in der Bauweise eines Kippstuhls. Die dort gewendete Bramme wird auf eine stationäre Brammenablage positioniert, von dieser mittels der Quertransportwagen abgehoben und zurück auf den Schleiftisch transportiert. The facilities used for this purpose require for transporting and turning the slabs numerous mechanical components and a large hydraulic effort, in particular in addition to the turning devices still transport that receive the continuous casting product and feed the next processing station or maintain the Matehalfluss. Because on Rails movable transverse transport or undercarriage must first be driven onto the grinding table, for which purpose this must also be provided with rails, resulting in a heavy design, in order to remove the lifted with hydraulic supports slab of the grinding table can. The multiple, parallel next to each other on separate rails running cross transport car transport the acquired slab then to a stationary slab turning device, eg in the construction of a tilting chair. The slab turned there is positioned on a stationary slab deposit, lifted off the slab by means of the transverse transport carriage and transported back to the slab table.
Der Erfindung liegt daher die Aufgabe zugrunde, ein erheblich vereinfachtes Verfahren und eine Vorrichtung zum Handhaben beim Schleifen von stranggegossenen Brammen mit gleichzeitig stark verringertem baulichen Aufwand zu schaffen. The invention is therefore an object of the invention to provide a significantly simplified method and apparatus for handling the grinding of continuously cast slabs with a simultaneously greatly reduced structural complexity.
Diese Aufgabe wird mit einem Verfahren erfindungsgemäß dadurch gelöst, dass die Bramme von einem ein drehbares Brammenklemm- und -hebemittel aufweisenden Brammenmanipulator aufgenommen wird, mit dem die eingespannte Bramme sowohl quer transportiert als auch gewendet werden kann. Es lassen sich damit alle relevanten Funktionen zum Transportieren, Heben, Senken, Klemmen und Wenden der Brammen in einem Aggregat vereinheitlichen, nämlich dem multifunktionalen Brammenmanipulator, der dazu von einer zentralen Stelle aus programmiert bzw. gesteuert wird. This object is achieved by a method according to the invention in that the slab is taken up by a slab manipulator having a rotatable slab clamping and lifting means with which the clamped slab can be transversely transported as well as turned over. It can thus unify all the relevant functions for transporting, lifting, lowering, clamping and turning of slabs in an aggregate, namely the multifunctional slab manipulator, which is programmed from a central point or controlled.
Eine bevorzugte Ausgestaltung der Erfindung sieht vor, dass die auf dem Schleiftisch positionierte, auf einer stationären Ablage zwischengespeicherte oder von einem Rollgang zugeführte Bramme von dem Brammenmanipulator überfahren werden kann, der aus einer eine seitlich beabstandete Parallellage zu der Bramme einnehmenden Ausgangsposition herangefahren wird und die Bramme mit geöffnetem Brammenklemm- und -hebemittel umgreift, worauf das Bram- menklemm- und -hebemittel geschlossen und der Brammenmanipulator mit der eingespannten Bramme in eine Wendeposition verfahren wird, in der die Bramme durch Drehen des Brammenklemm- und -hebemittels gewendet und anschließend der Brammenmanipulator über den Schleiftisch gefahren, dort das Brammenklemm- und -hebemittel bis zur Auflage der Bramme auf dem Schleiftisch abgesenkt sowie dann geöffnet wird und der Brammenmanipulator nach dem Ablegen der Bramme in seine Ausgangsposition mit seitlicher Parallellage zu einer anderen Bramme verfahren wird. An der Abfolge ändert sich nichts, wenn die Bramme statt sogleich auf den Schleiftisch zur Zwischenspeicherung auf eine stationäre Ablage abgelegt wird. A preferred embodiment of the invention provides that the slab positioned on the grinding table, temporarily stored on a stationary tray or fed by a roller table, can be run over by the slab manipulator, which is moved up from a starting position engaging the laterally spaced parallel position to the slab and the slab with an open slab clamping and lifting means, whereupon the slab closed menklemm- and -hebemittel and the slab manipulator is moved with the clamped slab in a turning position in which the slab turned by turning the slab clamping and lifting means and then driven the slab manipulator on the grinding table, there the slab clamping and lifting means to Edition of the slab is lowered on the grinding table and then opened and the slab manipulator is moved to the laying of the slab in its starting position with lateral parallel position to another slab. Nothing changes in the sequence if the slab is placed on a stationary rack instead of immediately on the grinding table for intermediate storage.
Es lässt sich dadurch in bevorzugter Weise erreichen, dass der Brammenmanipulator beliebig zwischen mindestens einem vorhandenen Schleiftisch, einer oder mehreren stationären Brammenablagen sowie der Wendeposition und optional einem Rollgang zur Aufnahme einer zu schleifenden Bramme oder zum Abtransport der fertig geschliffenen Brammen quer verfahren werden kann. Der multifunktionale Brammenmanipulator, dessen Unterkonstruktion für die Fahrbahn bzw. - schienen des Quertransports sich aus Beton ausführen lässt, erfüllt somit alle logistischen Aufgaben. It can thereby be achieved in a preferred manner that the slab manipulator can be moved transversely between at least one existing grinding table, one or more stationary slab trays and the turning position and optionally a roller table for receiving a slab to be ground or for transporting the finished ground slabs. The multifunctional slab manipulator, whose substructure for the carriageway or rails of the transverse transport can be made of concrete, thus fulfills all logistical tasks.
Beim Betrieb von bevorzugt zwei im Abstand nebeneinander liegenden Schleifmaschinen lässt sich unter Zwischenspeicherung auf stationären Ablagen ein stetiger Schleifbetrieb und die kontinuierliche Belegung der gerade nicht schleifenden Schleifmaschineneinheit mit einer zu bearbeitenden Bramme gewährleisten. In der Ausgangsstellung des Transport- und Wendezyklus befindet sich die Bramme somit entweder auf einem Schleiftisch oder auf einer stationären Brammenablage. In der Wendeposition zwischen beispielsweise zwei stationären Brammenablagen und/oder den Schleifmaschineneinheiten findet der Brammenmanipulator ausreichend Freiraum, um die Bramme zum Schleifen der breitseitigen Oberflächen um 180° zu wenden. Eine erfindungsgemäße Vorrichtung, insbesondere zur Durchführung des Verfahrens, sieht vor, dass im Auslaufbereich mindestens einer Schleifmaschineeinheit, in den der Schleiftisch mit der aufliegenden Bramme linear verfahren wird, ein dazu quer verfahrbarer Brammenmanipulator angeordnet ist, der einen die Länge des Schleiftisches überbückenden Fahrwerksrahmen mit darin an jeder Stirnseite innenliegenden, synchron angetriebenen Drehwerksrahmen aufweist, wobei die Drehwerksrahmen über jeweils eine untere und eine obere, in den Drehwerksrahmen heb- und senkbar angeordneten Hebetraverse miteinander verbunden sind und wobei die eine Hebetraverse mit eine Brammenoberfläche untergreifenden und die andere Hebetraverse mit die gegenüberliegende Brammenoberfläche übergreifenden Stützelementen versehen ist. Nach der Aufnahme der Bramme zwischen den beiden Hebetraversen trägt das eine Stützelement die Bramme, während sie durch Verstellen des anderen Stützelementes positioniert geklemmt bzw. eingespannt wird. In the operation of preferably two spaced adjacent grinders can be under caching on stationary shelves a steady grinding operation and ensure the continuous occupancy of the just not grinding grinding unit with a slab to be processed. In the initial position of the transport and turning cycle, the slab is thus either on a grinding table or on a stationary slab rest. In the turning position between, for example, two stationary slab trays and / or the grinding machine units, the slab manipulator finds enough clearance to turn the slab by 180 ° for grinding the broadside surfaces. A device according to the invention, in particular for carrying out the method, provides that in the outlet region of at least one grinding machine unit, in which the grinding table is moved linearly with the resting slab, a slab manipulator movable transversely thereto is arranged, which has a running gear frame overhanging the length of the grinding table having on each end inside, synchronously driven slewing frame, wherein the slewing frames are connected to each other via a lower and an upper, raised and lowered in the slewing frame lifting beam and wherein the one lifting beam with a slab surface under cross and the other lifting beam with the opposite slab surface is provided overarching support elements. After receiving the slab between the two lifting trusses that carries a support element, the slab, while it is positioned clamped by adjusting the other support member or clamped.
Zur Hubverstellung der die Bramme über- und untergreifenden Hebetraversen sind diese vorzugsweise über Hydraulikzylinder an die Drehwerksrahmen angelenkt sowie vorteilhaft in Führungen der Drehwerksrahmen angeordnet. For stroke adjustment of the slab over and under cross-lifting jacks these are preferably articulated via hydraulic cylinders to the slewing frame and advantageously arranged in guides the slewing frame.
Ein bevorzugter Vorschlag der Erfindung sieht vor, dass die Hebetraversen unabhängig voneinander heb- und senkbar sind. In der Aufnahmeposition braucht somit nur eine der Hebetraversen abgesenkt und dann von der Seite her unter die Bramme gefahren zu werden, bis sich diese mit ihrer Schmalseite an einen an den Hebetraversen vorteilhaft ausgebildeten Anschlag anlegt. Die untere Hebetraverse wird anschließend angehoben, während die obere Hebetraverse erst später zum Klemmen bzw. Einspannen der Bramme abgesenkt wird. Nach dem Wendevorgang übernimmt die untere Hebetraverse die Funktion der oberen Hebetraverse, und anschließend wieder umgekehrt. Das Wenden der Bramme lässt sich vorteilhaft dadurch erreichen, dass die Drehwerksrahmen mit einer von einem Drehantrieb betätigten Drehlagerung zu dem Fahrwerksrahmen ausgebildet sind. Als Drehantrieb kommt vorzugsweise ein Getriebemotor zum Einsatz. A preferred proposal of the invention provides that the lifting traverses are independently raised and lowered. In the receiving position thus needs only one of the lifting beams lowered and then driven from the side under the slab until it rests with its narrow side to an advantageously formed on the lifting traverse stop. The lower lifting beam is then raised while the upper lifting beam is lowered later to clamp or clamp the slab. After the turning process, the lower lifting beam takes over the function of the upper lifting beam, and then vice versa. The turning of the slab can be advantageously achieved in that the slewing frame are formed with a rotary bearing actuated by a rotary bearing to the chassis frame. As a rotary drive is preferably a geared motor used.
Nach einem weiteren Vorschlag der Erfindung ist vorgesehen, dass die Hebetraversen mit in Traversenlängsrichtung gesehen zueinander versetzten, zinkenartigen Tragstäben als Stützelemente versehen sind. Das Aufnehmen sowie Klemmen bzw. Einspannen der Bramme erfolgt hierbei mit linienförmigen Kontaktflächen und über die Länge der Bramme oben und unten versetzten Stützelementen. According to a further proposal of the invention it is provided that the lifting traverses are provided with offset in traverse longitudinal direction to each other, zinc-like support bars are provided as support elements. The recording and clamping or clamping of the slab takes place here with linear contact surfaces and over the length of the slab up and down offset support elements.
Hierzu sieht die Erfindung weiterhin vor, dass die Tragstäbe sich einander überlappend bis über die Hälfte der maximalen Brammenbreite und über die minimale Brammenbreite hinausgehend ausgebildet sind. Die Breite einer solchen zu handhabenden Bramme kann beispielsweise 800 mm bis 1.700 mm bei einer Länge von 5.000 mm bis 12.000 mm und Dicken von 150 mm bis 240 mm betragen. For this purpose, the invention further provides that the support rods are overlapping each other to over half of the maximum width of the slab and beyond the minimum slab width outgoing. The width of such a slab to be handled may be, for example, 800 mm to 1,700 mm with a length of 5,000 mm to 12,000 mm and thicknesses of 150 mm to 240 mm.
Die zinkenartigen Tragstäbe der unteren und oberen Hebetraverse weisen folglich von vornherein eine solche Länge auf, dass auf jeden Fall eine in dem beabsichtigten Breitenspektrum vorkommende Bramme sicher aufgenommen, geklemmt und gewendet werden kann. The tine-like support rods of the lower and upper lifting traverse thus have from the outset on such a length that in any case a occurring in the intended width spectrum slab can be safely picked up, clamped and turned.

On this grinding tables 12a, 12b are moved, which convey a machined or sanded slab in the grinding machine unit I or Il or convey out to turn the slab for grinding the other surface.
Der Brammenmanipulator besteht aus einem die Unterkonstruktion 6 mit den beiden Schienen 7a, 7b überspannenden, umfangsgeschlossenen Fahrwerksrahmen 13 (vgl. die Fig. 1 und 3). In diesem sind Brammenklemm- und -hebemittel 14, ausgebildet als untere Hebetraverse 14a und obere Hebetraverse 14b, vorgesehen, die mittels Hydraulikzylinder 15 in Führungen 16 (vgl. Fig. 4) unabhängig voneinander heb- und senkbar sind. Die Brammenklemm- und -hebemittel 14 sind zum Wenden einer aufgenommenen und eingespannten Bramme 2a bzw. 2b außerdem drehbar ausgebildet, wozu die untere sowie die obere Hebetraverse 14a bzw. 14b an ihren beiden Stirnenden in jeweils einem von dem Fahrwerksrahmen 13 getragenen Drehwerksrahmen 17a, 17b gelagert sind (vgl. Fig. 3). Die Drehwerksrahmen 17a, 17b sind mit einer von einem Drehantrieb 18, insbesondere Getriebemotor, betätigbaren Kugeldrehverbindung 19, wie in Fig. 5 schematisch angedeutet, zu dem Fahrwerksrahmen 13 ausgebildet. Der Drehbereich des Brammenmanipulators 9 ist in den Fig.2 und 5 als strichpunktierter Kreis 20 angedeutet (vgl. auch Fig. 4). Die untere und die obere Hebetraverse 14a, 14b ist mit zinkenartigen Tragstäben 21a bzw. 21 b als Stütz- und Übernahmeelemente versehen. Die Tragstäbe 21a der unteren Hebetraverse 14a sind in Traversenlängsrichtung gesehen gegenüber den Tragstäben 21 b der oberen Hebetraverse 14b versetzt angeordnet (vgl. Fig. 1 ). The slab manipulator consists of a subframe 6 with the two rails 7a, 7b spanning, circumferentially closed chassis frame 13 (see Figures 1 and 3). In this are slab clamping and lifting means 14, designed as lower lifting cross member 14a and upper lifting cross member 14b, are provided which can be raised and lowered independently of one another by means of hydraulic cylinders 15 in guides 16 (compare FIG. The slab clamping and lifting means 14 are also rotatably formed for turning a picked and clamped slab 2a and 2b, including the lower and upper lifting traverse 14a and 14b at their two front ends in each one carried by the chassis frame 13 slewing frame 17a, 17b are stored (see Fig. 3). The slewing gear frame 17a, 17b are formed with a rotatable drive 18, in particular gear motor, operable ball slewing connection 19, as indicated schematically in Fig. 5, to the chassis frame 13. The range of rotation of the slab manipulator 9 is indicated in FIGS. 2 and 5 as a dot-dashed circle 20 (see also FIG. 4). The lower and upper lifting traverse 14a, 14b is provided with tine-like support rods 21a and 21b as support and takeover elements. The support rods 21a of the lower lifting cross-member 14a are arranged offset in the traverse longitudinal direction relative to the support rods 21b of the upper lifting cross-member 14b arranged (see Fig. 1).
In der Ausgangsstellung des Transport- und Wendezyklus befindet sich die Bramme 2a bzw. 2b entweder auf einem Schleiftisch 12a, 12b oder auf einer stationären Ablage 10a, b, c oder d. Der Brammenmanipulator 9 kann auf der Unterkonstruktion 6 die stationären Brammenablagen 10a bis 10d und die Schleiftische 12a, 12b beliebig überfahren und somit eine gewünschte Verteilung der Brammen durchführen. Zur Übernahme einer Bramme wird der Brammenmanipulator 9 mit geöffneten Hebetraversen 14a, 14b in eine Parallellage zu entweder einer stationären Ablage 10a bis 10d oder zu einem Schleiftisch 12a, 12b verfahren, wie in Fig. 1 in der Position zu dem Schleiftisch 12b dargestellt. In the starting position of the transport and turning cycle, the slab 2a or 2b is either on a grinding table 12a, 12b or on a stationary tray 10a, b, c or d. The slab manipulator 9 can run over the stationary slab shelves 10a to 10d and the grinding tables 12a, 12b as desired on the substructure 6 and thus perform a desired distribution of the slabs. To take over a slab, the slab manipulator 9 is moved with opened lifting traverses 14a, 14b into a parallel position to either a stationary tray 10a to 10d or to a grinding table 12a, 12b, as shown in FIG. 1 in position to the grinding table 12b.
Sobald der Brammenmanipulator 9 einen Schleiftisch oder eine stationäre Brammenanlage überfahren hat und sich in einer seitlichen Parallellage dazu befindet, wird, wie am Beispiel der Fig. 6 und 6a bzw. 6b zu entnehmen, die untere Hebetraverse 14a aus der gestrichelten, angehobenen Position abgesenkt, der Brammenmanipulator dann unter die auf der im Ausführungsbeispiel der Fig. 6 auf der stationären Ablage 10c angehobene Bramme 2a bzw. 2b gefahren, wie mit durchgezogenen Linien verdeutlicht. Die Querfahrt des Brammenmanipulators 9 zum Untergreifen der Bramme wird beendet, sobald die Bramme 2a bzw. 2b auf einen Anschlag 22 der Hebetraverse 14a trifft. As soon as the slab manipulator 9 has crossed over a grinding table or a stationary slab system and is in a lateral parallel position, as can be seen from the example of FIGS. 6 and 6a or 6b, the lower lifting cross member 14a is lowered from the dashed, raised position, the slab manipulator then moved under the on the in the embodiment of Fig. 6 on the stationary tray 10c raised slab 2a and 2b, as illustrated by solid lines. The transverse travel of the slab manipulator 9 for reaching under the slab is stopped as soon as the slab 2a or 2b hits a stop 22 of the lifting traverse 14a.
Die untere Hebetraverse 14a mit der aufliegenden Bramme wird dann angehoben und anschließend die obere Hebetraverse 14b zum Einspannen der Bramme nach unten abgesenkt, wie in Fig. 6a für eine Bramme 2a mit maximalen Abmessungen und in Fig. 6b für eine Bramme 2b mit minimalen Abmessungen dargestellt. Zum Wenden wird der Brammenmanipulator 9 in eine einen ausreichenden Freiraum bietende Wendeposition (W) verfahren, wie in Fig. 2 zwischen den beiden stationären Brammenablagen 10b und 10c (vgl. auch Fig. 5) angedeutet. Nach dem Wenden übernimmt die untere Hebetraverse 14a die Funktion der oberen Hebetraverse 14b und umgekehrt. Die solchermaßen gewendete Bramme 2a bzw. 2b kann von dem Brammenmanipulator durch Querfahrt auf den stationären Brammenablagen 10a bis 10d zur Zwischenspeicherung abgelegt oder sogleich auf einen Schleiftisch 12a oder 12b positioniert werden, der die Bramme mit der zur Schleifbearbeitung oben liegenden Fläche in die Schleifmaschineneinheit I oder Il einfährt. The lower lifting beam 14a with the resting slab is then lifted and then the upper lifting beam 14b is lowered for clamping the slab, as in Fig. 6a for a slab 2a of maximum dimensions and in Fig. 6b for a slab 2b having minimal dimensions. For turning, the slab manipulator 9 is moved into a turning position (W) offering sufficient clearance, as indicated in FIG. 2 between the two stationary slab trays 10b and 10c (see also FIG. After turning, the lower lifting beam 14a assumes the function of the upper lifting beam 14b and vice versa. The thus turned slab 2a or 2b can be stored by the slab manipulator by transversely on the stationary slab trays 10a to 10d for temporary storage or positioned immediately on a grinding table 12a or 12b, the slab with the surface for grinding machining in the grinding machine unit I or Il enters.
