Description

Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zum Umlegen von mit Zapfen in einem Gehänge schwenkbar gelagerten metallurgischen Gefäßen, insbesondere Gießpfannen.The present invention relates to a method and a device for transferring with pins in a hanger pivotally mounted metallurgical vessels, in particular ladles.

Derartige Vorrichtungen zum Umlegen von mit Zapfen in einem Gehänge schwenkbar gelagerten metallurgischen Gefäßen, insbesondere Gießpfannen, werden Kippstuhl oder Pfannenkippstuhl genannt und sind im Stand der Technik in zahlreichen Ausgestaltungen bekannt. Verwendung finden derartige Kippstühle insbesondere in Hüttenbetrieben im Rahmen der Stahlerzeugung bzw. Stahlherstellung.Such devices for transferring with spigots in a hanger pivotally mounted metallurgical vessels, especially ladles are called tilting chair or pan and tilting chair and are known in the art in numerous embodiments. Such tilting chairs are used especially in metallurgical plants in the context of steelmaking and steelmaking.

Bei der Stahlherstellung werden metallurgische Gefäße, insbesondere Gießpfannen, zum Transport von flüssigem Stahl benutzt. Bei den Gießpfannen handelt es sich um feuerfest zugestellte Gefäße, welche in ihrem oberen Teil zwei Gehängezapfen aufweisen, an denen je ein Gehänge drehbar gelagert befestigt ist. Bei den Gehängen kann es sich auch um den Haken oder dergleichen Lastaufnahmemittel eines Krans oder dergleichen Hebezeugs handeln, der bzw. welches an dem Zapfen des metallurgischen Gefäßes schwenkbar angreift. Transportiert werden Gießpfannen in der Regel mittels eines Krans oder dergleichen Hebezeugs. Beim Transport einer Gießpfanne mittels eines Kranes greifen über eine Traverse mit dem Hubantrieb des Kranes verbundene Kranhaken in die beiden Gehänge ein. Die Gehängezapfen der Gießpfanne sind in einem oberen Bereich derselben derart an dieser angeordnet, dass durch die Lage der Gehängezapfen an der Gießpfanne der Schwerpunkt der Gießpfanne immer unterhalb der Zapfen bzw. der Achse der Zapfen liegt, so dass eine im Kran an Gehängen hängende Gießpfanne immer vertikal, das heißt in einer vertikalen Lage hängt.In steelmaking, metallurgical vessels, especially ladles, are used to transport liquid steel. The ladles are fireproof containers, which have in their upper part two suspension pins, on each of which a hanger is mounted rotatably mounted. The hangers can also be the hook or the like load-carrying means of a crane or similar hoist, which engages pivotally on the pin of the metallurgical vessel. Ladles are usually transported by means of a crane or similar hoist. When transporting a ladle by means of a crane, crane hooks connected to the lifting drive of the crane engage in the two hangers via a cross-beam. The pegs of the ladle are arranged in an upper portion of the same at this, that the center of gravity of the ladle is always below the pin or the axis of the pin through the location of the hanger pin on the ladle, so that in the crane hanging on hangers ladle always vertically, that is, hanging in a vertical position.

Im Boden der Gießpfannen sind üblicherweise Absperrorgane für den flüssigen Stahl - sogenannte Pfannenschieber - sowie sogenannte, einer Einleitung von Inertgas zur Homogenisierung der Stahlschmelze dienende Spülsteine eingebaut. Die Pfannenschieber dienen zum Ausleeren der Schmelze in Kokillen oder Gießmaschinen. Pfannenschieber weisen in der Regel verschiedene keramische, insbesondere feuerfestkeramische Verschleißteile auf. Nach jeder Pfannenentleerung müssen die keramischen Verschleißteile des Pfannenschiebers gereinigt, kontrolliert oder gewechselt werden. Nach bestimmten Intervallen müssen längere Zeiten in Anspruch nehmende Wartungs- und/oder Reparaturarbeiten, wie beispielsweise ein Wechsel bzw. Austauschen des Pfannenschiebers oder ein Wechseln bzw. Austauschen der Spülsteine durchgeführt werden.In the bottom of the ladles usually shut-off devices for the liquid steel - so-called pan valves - and so-called, an introduction of inert gas for homogenizing the molten steel serving purge stones are installed. The pan valves are used to empty the melt in molds or casting machines. Pans slide usually have various ceramic, especially refractory ceramic wear parts. After each ladle emptying, the ceramic wear parts of the ladle slide must be cleaned, checked or replaced. After certain intervals longer periods of maintenance and / or repair work, such as a replacement or replacement of the pan slider or a change or replacement of the sinks must be performed.

Die ohnehin überaus personal- und betriebsmittelaufwendigen Arbeiten am Boden der Gießpfannen machen darüber hinaus umfangreiche Vorarbeiten zur Durchführung der Arbeiten, insbesondere Wartungs- und/oder Reparaturarbeiten an den Pfannenschiebern und Spülsteinen der Gießpfannen erforderlich. So sind die Gießpfannen im Hüttenbetrieb in der Regel über große Wege in von der eigentlichen Stahlerzeugung entfernte Nachbarhallen zu transportieren und dort zur Durchführung der Arbeiten am Boden der Gießpfannen von einer vertikalen Lage in eine horizontale Lage umzulegen. Für die Vorbereitungsarbeiten zum Arbeiten am Pfannenboden ist insofern ebenfalls ein hoher Personal- und Betriebsmittelaufwand, insbesondere für Krane, Flurfahrzeuge und dergleichen erforderlich. Diese Arbeiten sind derart zeitintensiv, dass die Temperatur (Steintemperatur) der Gießpfanne so weit absinkt, dass die Gießpfanne nach den Wartungs- und/oder Reparaturarbeiten erst wieder aufgeheizt werden muss, um bestimmungsgemäß verwendet werden zu können. Vor dem Hintergrund dieser in einem Hüttenbetrieb, insbesondere einem Stahlwerk, zu bewältigenden Logistik müssen in Hüttenbetrieben, insbesondere Stahlwerken, immer mehr auf bestimmungsgemäßer Betriebstemperatur aufgeheizte Gießpfannen bevorratet gehalten werden, als eigentlich notwendig.In addition, the extremely labor-intensive and resource-intensive work on the bottom of the ladles also requires extensive preparatory work to carry out the work, in particular maintenance and / or repair work on the ladles and pans of the ladles. Thus, the ladles in metallurgical operations are generally to be transported over long distances in the neighboring steel halls remote from the actual steelmaking and to transfer there from the vertical position to a horizontal position to carry out the work on the bottom of the ladles. As far as the preparatory work for working on the bottom of the pan is also a high personnel and equipment costs, especially for cranes, floor vehicles and the like required. This work is so time-consuming that the temperature (stone temperature) of the ladle drops so far that the ladle must first be reheated after maintenance and / or repair work to be able to be used properly. Against the background of this logistics to be mastered in a metallurgical plant, in particular a steelworks, in metallurgical plants, in particular steel mills, more and more ladles, heated to the intended operating temperature, must be kept stored, as actually necessary.

Es ist bekannt, Gießpfannen zur Durchführung der Arbeiten am Boden derselben mit Hilfe eines Kranes mit zwei Hubeinrichtungen bzw. Hüben von einer vertikalen Lage in eine horizontale Lage umzulegen. Dabei wird eine in einem Kran an ihren Gehängen in vertikaler Lage hängende Gießpfanne mittels eines zweiten Kranhubes, der im Bodenbereich der Gießpfanne angeschlagen wird, in der Luft um die Achse ihrer Gehängezapfen um 90° gedreht und so in eine horizontale Lage verbracht. Die sich in horizontaler Lage befindliche Gießpfanne wird dann in einem Bock abgelegt. Nachteilig und gefahrenträchtig ist dabei insbesondere das Hantieren mit der etwa 120 t und mehr schweren Gießpfanne in der Luft.It is known to transfer ladles for carrying out the work on the ground thereof by means of a crane with two lifting devices or strokes from a vertical position to a horizontal position. In this case, a ladle hanging in a crane on its hangers in a vertical position by means of a second crane stroke, which is struck in the bottom region of the ladle, in the air rotated about the axis of their pegs by 90 ° and so spent in a horizontal position. The ladle, which is in a horizontal position, is then placed in a box. Disadvantageous and risky is in particular the handling of about 120 t and more heavy ladle in the air.

Weiterhin ist es bekannt, Gießpfannen von einer vertikalen Lage in eine horizontale Lage mittels der Eingangs genannten Kippvorrichtungen, - sogenannte Kippstühle - umzulegen. Dabei wird eine in einem Kran an ihren Gehängen in vertikaler Lage hängende Gießpfanne von dem Kran in vertikaler Lage in die Gehänge der Gießpfanne aufnehmende Aufnahmetaschen der Kippvorrichtung abgestellt und dann unabhängig vom Kran mittels hydraulischer und/oder elektromechanischer Antriebe in die horizontale Lage gedreht bzw. gekippt. Die Antriebe und die Gießpfannenhaltevorrichtungen der bisher bekannten Kippstühle sind raumbeanspruchend, technisch aufwendig und überaus kostenintensiv.It is also known to transfer ladles from a vertical position to a horizontal position by means of the tilting devices mentioned at the beginning, so-called tilting chairs. Here, a hanging in a crane on their hangers in a vertical position ladle is parked by the crane in a vertical position in the hanger of the ladle receiving pockets of the tilting device and then rotated or tilted independently of the crane by means of hydraulic and / or electromechanical drives in the horizontal position , The drives and the Gießpfannenhaltevorrichtungen previously known tilting chairs are space consuming, technically complex and extremely expensive.

Der Erfindung liegt in Anbetracht dieses Standes der Technik die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum Umlegen von mit Zapfen in einem Gehänge schwenkbar gelagerten metallurgischen Gefäßen, insbesondere Gießpfannen, bereitzustellen, welche unter Meidung der beschriebenen Nachteile auf kostengünstige Art und Weise ein einfaches, sicheres und schnelles Umlegen von Gießpfannen ermöglichen und insbesondere die Verwendung von Antrieben oder zweiten Kranhuben entbehrlich machen.The invention is in view of this prior art, the object to provide a method and apparatus for transferring pivotally mounted with pins in a hanger metallurgical vessels, in particular ladles, which, while avoiding the disadvantages described in a cost effective manner a simple, enable safe and fast transfer of ladles, and in particular make the use of drives or second crane maneuvers dispensable.

Die Aufgabe ist erfindungsgemäß dadurch gelöst, dass ein metallurgisches Gefäß durch die auf dieses wirkende Gravitationskraft um die Achse seiner Zapfen von einer vertikalen Lage in eine horizontale Lage umgelegt wird.The object is inventively achieved in that a metallurgical vessel is turned over by the force acting on this gravitational force about the axis of its pin from a vertical position to a horizontal position.

Der Erfindung liegt die Erkenntnis zugrunde, dass ein metallurgisches Gefäß ohne jegliche Antriebe einfach sicher und schnell mit Hilfe der auf das metallurgische Gefäß wirkenden Gravitationskraft um die Achse seiner Zapfen verschwenkt und von einer vertikalen Lage in eine horizontale Lage umgelegt werden kann.The invention is based on the finding that a metallurgical vessel without any drives can be simply safely and quickly pivoted about the axis of its pins with the aid of the gravitational force acting on the metallurgical vessel and transferred from a vertical position into a horizontal position.

Die Erfindung ermöglicht so insbesondere die für einen Gießprozess im Rahmen der Stahlerzeugung in einem Hüttenbetrieb erforderlichen Reparatur- und/oder Wartungsarbeiten an Gießpfannen mit den dazu gegebenenfalls notwendigen Nebenaggregaten in kürzester Zeit durchführen zu können. Die für diese Arbeiten am Boden und im Innern der Gießpfannen zum Einsatz kommenden Nebenaggregate, wie beispielsweise De- und/oder Montagevorrichtungen für Lochsteine seitens des Gießpfannenausgusses, Spülsteine, Pfannenschieber und Pfannenschieberkeramiken, Lasermesseinrichtungen mit oder ohne Spritzrobotern und Putzeinrichtungen für die feuerfeste Ausmauerung der Gießpfannen, können erfindungsgemäß schnellstmöglich genutzt werden. Ferner kann ein horizontal brennendes Pfannenfeuer erfindungsgemäß schnellstmöglich zum Einsatz kommen.The invention thus makes it possible in particular to be able to carry out the repair and / or maintenance work on ladles with the ancillary units necessary for a casting process within the framework of steel production in a metallurgical plant in the shortest possible time. The ones used for this work on the ground and inside the ladles Auxiliary devices, such as de- and / or mounting devices for perforated bricks on the part of the ladle nozzle, purging, pan and pan pusher ceramics, laser measuring devices with or without spray robots and plasters for fireproof lining of the ladles, can be used as quickly as possible according to the invention. Furthermore, according to the invention, a horizontally burning ladle fire can be used as quickly as possible.

Vorteilhafterweise hängt das metallurgische Gefäß wenigstens beim Umlegen mit seinen Gehängen an einem Tragmittel oder an einem Lastaufnahmemittel eines Krans. Dadurch wird das Gewicht des metallurgischen Gefäßes von dem Kran gehalten, so dass entsprechende, das metallurgische Gefäß aufnehmende Aufnahmevorrichtungen am Boden lediglich entsprechend geringere Lasten aufnehmen und bewegen können und dementsprechend weniger aufwendig ausgestaltet sein müssen. Ferner ist dadurch die Sicherheit beim Hantieren des metallurgischen Gefäßes erhöht, insbesondere da dass metallurgische Gefäß wenigstens beim Umlegen von einer vertikalen Lage in eine horizontale Lage im Kran hängt.Advantageously, the metallurgical vessel hangs at least when moving with its hangers on a support means or on a load-carrying means of a crane. As a result, the weight of the metallurgical vessel is held by the crane so that corresponding receiving devices accommodating the metallurgical vessel can only absorb and move correspondingly lower loads on the ground and accordingly have to be made less expensive. Furthermore, this increases the safety when handling the metallurgical vessel, in particular because the metallurgical vessel hangs at least when moving from a vertical position to a horizontal position in the crane.

Fig. 1 und Fig. 2 zeigen eine im Stand der Technik bekannte Stahlgießpfanne 1. Das metallurgischen Gefäß 1 der Stahlgießpfanne ist mit im oberen Bereich an einander gegenüberliegenden Seiten des Gefäßes 1 angeordneten Zapfen 2 in Gehängen 3 schwenkbar gelagert. Im unteren Bereich des metallurgischen Gefäßes 1 sind an diesem an einander gegenüberliegenden Seiten Anschläge 4 angeordnet, welche zur Führung und/oder Positionierung des metallurgischen Gefäßes 1 dienen.Fig. 1 and Fig. 2 show a known in the prior art steel ladle 1. The metallurgical vessel 1 of the steel ladle is pivotally mounted in the upper region on opposite sides of the vessel 1 arranged pin 2 in hangers 3. In the lower region of the metallurgical vessel 1 stops 4 are arranged on this on opposite sides, which serve for guiding and / or positioning of the metallurgical vessel 1.

Fig. 3 und Fig. 4 zeigen eine Vorrichtung zum Umlegen einer Stahlgießpfanne 1 nach Fig. 1 und Fig. 2 von einer vertikalen Lage in eine horizontale Lage. Die Vorrichtung besteht aus zwei parallel zueinander und beabstandet voneinander angeordneten, drehbar um die Achse 10 in Böcken 5 gelagerten Schwingen 6. Die Schwingen 6 weisen vorliegend jeweils zwei im wesentlichen L-förmige Schwingenarme auf, welche im wesentlichen rechtwinklig zueinander angeordnet sind und jeweils ein freies Ende E1 bzw. E2 aufweisen. An dem freien Ende E1 der Schwingen 6 ist eine taschenartige Aufnahme 8 zur lagernden Aufnahme eines Gehänges 3 des metallurgischen Gefäßes 1 drehbar um die Achse 9 gelagert angeordnet. An dem anderen freien Ende E2 der Schwingen 6 ist ein Gewicht 15 angeordnet.FIG. 3 and FIG. 4 show a device for transferring a steel ladle 1 according to FIG. 1 and FIG. 2 from a vertical position to a horizontal position. The device consists of two mutually parallel and spaced apart, rotatably mounted about the axis 10 in girders 5 wings 6. The wings 6 each have two substantially L-shaped swing arms, which are arranged substantially at right angles to each other are and each have a free end E1 and E2. At the free end E1 of the rockers 6, a pocket-like receptacle 8 for supporting a hanger 3 of the metallurgical vessel 1 is mounted rotatably mounted about the axis 9. At the other free end E2 of the rockers 6, a weight 15 is arranged.

Die Schwingenarme der Schwingen 6, insbesondere der Abstand a zwischen der Schwingenachse 10 und der Achse 9 der taschenartigen, im wesentlichen U-förmigen Aufnahme 8 zur lagernden Aufnahme eines Gehänges 3 des metallurgischen Gefäßes 1 und der Abstand b zwischen der Schwingenachse 10 und dem Gewicht 15, sind derart bemessen und ausgestaltet, dass das an dem die taschenartige Aufnahme 8 zur lagernden Aufnahme eines Gehänges 3 des metallurgischen Gefäßes 1 aufweisenden freien Ende E1 der Schwinge 6 erzeugte Moment bei nicht aufgenommenem metallurgischen Gefäß 1 geringer und bei aufgenommenem metallurgischen Gefäß 1 größer ist als das an dem anderen freien Ende E2 der Schwinge 6 durch das Gewicht 15 erzeugte Moment.The swing arms of the rockers 6, in particular the distance a between the rocker axis 10 and the axis 9 of the pocket-like, substantially U-shaped receptacle 8 for supporting a hanger 3 of the metallurgical vessel 1 and the distance b between the rocker axis 10 and the weight 15th , Are dimensioned and designed so that the generated at the pocket-like receptacle 8 for supporting a hanger 3 of the metallurgical vessel 1 having free end E1 of the rocker 6 generated momentum is lower when not received metallurgical vessel 1 and metallurgical vessel 1 is greater than the torque generated at the other free end E2 of the rocker 6 by the weight 15.

Die Schwingen 6 weisen im Bereich des anderen freien Endes E2 am entsprechenden Schwingenarm mit den an dem metallurgischen Gefäß 1 angeordneten Anschlägen 4 zusammenwirkende Mitnehmer 7 auf. Weiter weisen die Schwingen im Bereich des freien Endes E1 am entsprechenden Schwingenarm einen die Bewegung der taschenartigen Aufnahme 8 zur lagernden Aufnahme eines Gehänges 3 des metallurgischen Gefäßes 1 begrenzenden Anschlag 11 auf, durch welchen die drehbar um die Achse 9 gelagert angeordnete taschenartigen Aufnahme 8 am freien Ende E1 der Schwinge 6 in einer zur lagernden Aufnahme eines Gehänges 3 des metallurgischen Gefäßes 1 geeigneten Position gehalten wird.The rockers 6 have in the region of the other free end E2 on the corresponding rocker arm with the arranged on the metallurgical vessel 1 stops 4 driver 7 on. Next, the wings in the region of the free end E1 on the corresponding swing arm on a movement of the pocket-like receptacle 8 for supporting receiving a hanger 3 of the metallurgical vessel 1 limiting stop 11, through which the rotatably mounted about the axis 9 arranged pocket-like receptacle 8 at the free End E1 of the rocker 6 is held in a suitable storage for receiving a hanger 3 of the metallurgical vessel 1 position.

Die Böcke 5 sind aus Stahl gefertigt und fest mit einer Bodenplatte 14 aus Stahl verschweißt und/oder verschraubt. Der Abstand zwischen den Böcken 5 ist derart ausgebildet, dass zwischen diesen das metallurgische Gefäß 1 aufgenommen werden kann. Die Böcke 5 weisen einen mit dem die taschenartige Aufnahme 8 zur lagernden Aufnahme eines Gehänges 3 des metallurgischen Gefäßes 1 aufweisenden freien Ende E1 der Schwingen 6 zusammenwirkenden Anschlag 13 und einen mit dem am anderen freien Ende E2 der Schwingen 6 mit dem Gewicht 15 zusammenwirkender Anschlag 12 auf. Die Anschläge 12 und 13 dienen der Begrenzung der Bewegung der Schwingen 6.The blocks 5 are made of steel and firmly welded to a bottom plate 14 made of steel and / or screwed. The distance between the blocks 5 is formed such that between them the metallurgical vessel 1 can be accommodated. The blocks 5 have a with the pocket-like receptacle 8 for supporting receiving a hanger 3 of the metallurgical vessel 1 having free end E1 of the wings 6 cooperating stop 13 and with the other at the other free end E2 of the wings 6 with the weight 15 cooperating stop 12th on. The stops 12 and 13 serve to limit the movement of the rockers. 6

Die drehbar gelagerten Schwingen 6 werden mittels der Gewichte 15 auf die Anschläge 12 gedrückt. In dieser Stellung fixieren die Anschläge 11 für die drehbar gelagerten taschenartigen Aufnahmen 8 in Aufnahmeposition für die vertikal hängenden Gehänge 3 der Stahlgießpfanne 1. In Aufnahmeposition steht die Schwinge 6 - wie in Fig. 3 und Fig. 5 dargestellt - bedingt dadurch, dass das Moment Gewicht 15 mal Abstand b größer ist als das Moment des Gewichtes der Aufnahmetasche 8 mal Abstand a. Durch eine Stahlgießpfanne 1, die mit ihrer Masse vertikal von oben nach unten in die taschenartigen Aufnahmen 8 mit der Kraft F drückt und ein größeres Moment erzeugt als das Moment aus Gewicht 15 mal Abstand b drehen sich die Schwingen 6 um die Schwingenachse 10 in einem Kreisbogen bzw. Kreisbodenabschnitt, wobei die taschenartigen Aufnahmen 8, bedingt durch ihre drehbare Lagerung um die Achse 9 mit den in diesen liegend aufgenommenen bzw. fixierten Pfannengehängen 3 immer in vertikaler Lage verbleiben.The rotatably mounted rockers 6 are pressed by means of the weights 15 on the stops 12. In this position, fix the stops 11 for the rotatably mounted pocket-like receptacles 8 in the receiving position for the vertically hanging hanger 3 of the steel ladle 1. In receiving position the rocker 6 - as shown in Fig. 3 and Fig. 5 - due to the fact that the moment Weight 15 times distance b is greater than the moment of the weight of the receiving pocket 8 times distance a. Through a steel ladle 1, which presses vertically with their mass from top to bottom in the pocket-like receptacles 8 with the force F and generates a larger moment than the moment of weight 15 times distance b, the wings rotate 6 about the swing arm 10 in a circular arc or circular bottom portion, wherein the pocket-like receptacles 8, due to their rotatable mounting about the axis 9 with the lying in these lying or fixed pan hangers 3 always remain in a vertical position.

Die in Kranhaken hängende Stahlgießpfanne 1 wird von dem Kran abgesenkt und mit ihren Gehängen 3 in die taschenartigen Aufnahmen 8 abgelegt. Die Schwingen 6 bzw. taschenartigen Aufnahmen 8 geben dem Gewicht nach und beschreiben einen Kreisbogen bzw. Kreisbogenabschnitt nach unten, vorliegend - wie anhand von Fig. 5 und Fig. 6 zu erkennen - entgegen dem Uhrzeigersinn. Diesem Kreisbogen bzw. Kreisbogenabschnitt nach unten folgt während der Absenkfahrt der Kran mit seiner Katzfahrt. Die Pfannenmitnehmer 7 beschreiben dementsprechend mit dem unteren Teil der Stahlgießpfanne 1 einen Kreisbogen nach oben, wie anhand von Fig. 5 und Fig. 6 zu erkennen - entgegen dem Uhrzeigersinn. Nachdem die Pfanne um ca. 90° gedreht wurde und horizontal liegt, legen sich bei Gewichtsentlastung des Kranes die taschenartigen Aufnahmen 8 auf die Aufnahmetaschenablager 13 und die Gehänge 3 fest in den taschenartigen Aufnahmen 8 ab und die Stahlgießpfanne 1 liegt horizontal. Der Kran kann seine Haken aus den Gehängen 3 ausfahren bzw. ausfädeln.The hanging in crane hooks steel ladle 1 is lowered by the crane and stored with their hangers 3 in the pocket-like receptacles 8. The rockers 6 and pocket-like receptacles 8 give the weight and describe a circular arc or circular arc portion down, present - as can be seen from Fig. 5 and Fig. 6 - counterclockwise. This circular arc or circular arc section downwards follows the crane during its descent with its cat travel. The Pfannenmitnehmer 7 describe accordingly with the lower part of the Stahlgießpfanne 1 a circular arc upwards, as can be seen with reference to FIG. 5 and FIG. 6 - in the counterclockwise direction. After the pan has been rotated by approximately 90 ° and is horizontal, the pocket-like receptacles 8 are placed on the receiving pocket depositors 13 and the hangers 3 firmly in the pocket-like receptacles 8 and the casting ladle 1 is horizontal when weight is relieved of the crane. The crane can extend or unthread its hooks from the hangers 3.

Die Entnahme der Pfanne erfolgt in umgekehrter Reihenfolge. Der Kran fädelt seine Haken in die Gehänge 3 ein und hebt die Stahlgießpfanne an. Während der Hebefahrt folgt der Kran dem Kreisbogen bzw. Kreisbogenbahn der Gehänge 3 mit der Katzfahrt.The removal of the pan is done in reverse order. The crane threads its hooks into the hangers 3 and raises the steel ladle. During the lifting, the crane follows the circular arc of the hangers 3 with the trolley.

Ohne Zwischenstopp kann der Kran die Stahlgießpfanne aus der Vorrichtung heben. Dies kann beispielsweise in der Hauptproduktionshalle eines Hüttenbetriebes im Rahmen der Stahlerzeugung mit kurzen Wegen so gewährleistet werden, dass die Umlegevorrichtung so weit die Katzfahrt des Kranes es erlaubt am Rande einer Halle aufgestellt sein kann. Die zu reparierende bzw. wartende Stahlgießpfanne 1 ist während der Absenkfahrt des Kranes ohne jegliche Zeitverluste so umlegbar, dass der Pfannenboden unterhalb der Kranbahn gelangt. Außerhalb des Krananfahrbereiches unter der Kranbahn und angrenzend zu einer Nachbarhalle sind Wartung und/oder Reparatur am Pfannenboden ohne jegliche zusätzlichen Transporte und Aktionen umgehend mit den notwendigen Nebenaggregaten ermöglicht.Without stopping, the crane can lift the ladle out of the device. This can be done, for example, in the main production hall of a Hüttenbetriebes in the context of steel production with short distances are guaranteed so that the transfer device as far as the trolley of the crane allows it may be placed on the edge of a hall. The steel ladle 1 to be repaired or serviced during the descent of the crane without any loss of time so umweigbar that the pan bottom passes below the crane runway. Outside the crane approach area under the crane runway and adjacent to a neighboring hall, maintenance and / or repair on the ladle floor are made possible without any additional transports and actions immediately with the necessary ancillary units.

Während beispielsweise ein Wechsel des Pfannenschiebers bei konventioneller Vorgehensweise etwa zwei Stunden Bearbeitungszeit und etwa zwei Stunden Aufheizzeit benötigt, ist mit der Umlegevorrichtung die Arbeit innerhalb kürzester Zeit, in etwa fünf bis zehn Minuten durchführbar, so dass die Verfügbarkeit der Stahlgießpfanne um etwa nahezu vier Stunden steigerbar ist. Dementsprechend ist die Vorhaltung zum Transport der Stahlgießpfanne, von Flurfahrzeugen, Kranen, Pfannenfeuern, Personal und dergleichen entbehrlich.For example, while a change of the pan slider with conventional approach about two hours of processing time and about two hours of heating time is required, the work within a very short time in about five to ten minutes feasible, so that the availability of the steel ladle can be increased by about four hours is. Accordingly, the provision for the transport of the steel ladle, corridors, cranes, ladles, personnel and the like is unnecessary.

Bei dem in Fig. 7 mit aufgenommener und umgelegter Stahlgießpfanne 1 dargestellten Ausführungsbeispiel einer Vorrichtung zum Umlegen einer Stahlgießpfanne 1 nach Fig. 1 und Fig. 2 von einer vertikalen Lage in eine horizontale Lage ist der die Bewegung der Schwingen 6 bzw. der taschenartigen Aufnahmen 8 begrenzende Anschlag 13 mittels Plungerzylindern 16 als Kurzhubeinrichtungen höhenverstellbar ausgebildet, insbesondere um den Boden 17 der Stahlgießpfanne 1 in eine senkrecht zur Bodenplatte 14 bzw. zum Erdboden verlaufende Lage ausrichten zu können.In the exemplary embodiment of a device for transferring a steel ladle 1 according to FIG. 1 and FIG. 2 from a vertical position to a horizontal position shown in FIG. 7, the movement of the rockers 6 or the pocket-like receptacles 8 is shown limiting stop 13 by means of Plungerzylinders 16 designed as short-stroke height adjustable, in particular to align the bottom 17 of the ladle 1 in a direction perpendicular to the bottom plate 14 and the ground extending position.
