Stand der TechnikState of the art

Ein Schieberverschluss der gattungsbildenden Art ist beispielsweise aus der WO 03/080274 bereits bekannt. Dieser Schieberverschluss ist als Zweiplattenschieber ausgebildet, wobei eine bewegliche Verschlussplatte mit einem hydraulischen Stellglied zwischen einer "Offen-Position", die den Durchtritt von Metallschmelze ermöglicht, und einer "Geschlossen-Position", die den Durchfluss sperrt, verlagerbar ist.A slider closure of the generic type is for example from the WO 03/080274 already known. This slide closure is designed as a two-plate slide, wherein a movable closure plate with a hydraulic actuator between an "open position", which allows the passage of molten metal, and a "closed position", which blocks the flow, is displaced.

Eine kompakte Baugruppe bestehend aus einem Zweiplattenschieber und einem Gießrohr, welche durch eine Spanneinrichtung in der Betriebsposition verspannt wird und für einen gemeinsamen Ein- oder Ausbau freigegeben werden kann, ist aus der JP 5-318061 bekannt.A compact assembly consisting of a two-plate slide and a pouring tube, which is clamped by a clamping device in the operating position and can be released for a joint installation or removal, is from the JP 5-318061 known.

Schieberverschlüsse werden insbesondere bei Stranggießanlagen entweder an der Gießpfanne oder insbesondere am Verteilergefäß eingesetzt, um einen geregelten Zufluss von Metallschmelze in die Stranggießkokille und damit einen stabilen Gießvorgang zu gewährleisten. Feuerfeste Verschlussplatteneinsätze und die Gießrohre oder Schattenrohre sind Verschleißteile und müssen oft gewechselt werden. Vor Beginn des Gießvorganges sind die Ausgüsse der Schmelzenbehälter verschlossen und müssen mit besonderen Maßnahmen geöffnet werden. Dies erfordert eine leichte und gesicherte Manipulierbarkeit von beispielsweise einer Aufbrenneinrichtung in einem für das Betriebspersonal gefährlichen Umfeld.Slide closures are used in particular in continuous casting either on the ladle or in particular on the distribution vessel to ensure a controlled inflow of molten metal in the continuous casting mold and thus a stable casting process. Fireproof faceplate inserts and the casting tubes or shadow tubes are wearing parts and often need to be changed. Before starting the casting process, the spouts of the melt container are closed and must be opened with special measures. This requires a simple and secure manipulability of, for example, a firing device in a dangerous environment for the operating personnel.

Um ein Gießrohr oder Schattenrohr einerseits in seiner Betriebsposition am Schieberverschluss zu fixieren und mit einem bestimmten Anpressdruck an diesen anzupressen und andererseits einen Wechsel des Gießrohres durchführen zu können, sind bereits eine Reihe von Lösungen entwickelt geworden.In order to fix a pouring tube or shadow tube on the one hand in its operating position on the slide closure and to press with a certain contact pressure on this and on the other hand to perform a change of the pouring tube, a number of solutions have already been developed.

Beispielsweise ist in der EP 577 909 A1 ein Mechanismus zum Tragen und Andrücken eines Gießrohres an einem Auslass eines Zwischengefäßes bekannt, bei dem die Trageinrichtung einen um eine systemfremde Drehachse schwenkbaren zweiarmigen Hebel umfasst, an dessen einem Ende ein Aufnahmering für das Gießrohr und an seinem gegenüberliegenden Ende ein Gegengewicht zur Erzeugung eines Anpressdruckes auf das Gießrohr angeordnet ist. Eine genaue Positionierung der Gießdüse zur Austrittsöffnung für die Metallschmelze kann bei dieser Konstruktion jedoch nur durch eine selbstverschiebliche, damit jedoch verschmutzungsanfällige Hilfsdüse erreicht werden.For example, in the EP 577 909 A1 a mechanism for carrying and pressing a pouring tube at an outlet of an intermediate vessel known in which the support means comprises a pivotable about a system foreign axis two-armed lever, at one end a receiving ring for the pouring tube and at its opposite end a counterweight for generating a contact pressure the pouring tube is arranged. A precise positioning of the casting nozzle to the outlet for the molten metal can be achieved in this construction, however, only by a self-displaceable, but so prone to contamination auxiliary nozzle.

Aus der US 4,892,235 ist eine Trag- und Andrückvorrichtung für eine Gießdüse bekannt, mit der das Gießrohr an eine stationäre Verschlussplatte eines Dreiplattenschiebers angedrückt werden kann. Eine um eine vertikale Achse ein- und ausschwenkbare Gabelaufnahme für das Gießrohr umfasst als Federelemente ausgebildete Tragstäbe, mit denen nach dem Einschwenken eines Sicherungsanschlages eine im Wesentlichen vorbestimmte Andrückkraft erzeugt werden kann. Eine Reihe von Manipulationen ist hier händisch vorzunehmen, um einen Wechsel des Gießrohres durchführen zu können, wodurch die Sicherheit des Betriebspersonals wesentlich beeinträchtigt wird.From the US 4,892,235 a support and pressing device for a casting nozzle is known, with which the pouring tube can be pressed against a stationary closure plate of a three-plate pusher. A fork receptacle for the pouring tube, which can be pivoted in and out about a vertical axis, comprises support rods designed as spring elements, with which a substantially predetermined pressing force can be generated after the pivoting of a securing stop. A series of manipulations must be carried out manually in order to carry out a change of the pouring tube, whereby the safety of the operating personnel is significantly impaired.

Weiters sind die beschriebenen Wechseleinrichtungen für Gieß- und Schattenrohre für eine Anwendung bei Zweiplattenschiebem nicht geeignet, bei denen das Gieß- oder Schattenrohr an der beweglichen Verschlussplatte befestigt werden soll.Furthermore, the described changing devices for casting and shadow tubes for use in Zweiplattenschiebem are not suitable in which the casting or shadow tube to be attached to the movable closure plate.

Die verschiebbare Verschlussplatte trägt einen Anschlussring für die zentrierte Aufnahme des Gießrohrs. Die Wechseleinrichtung besteht aus Zylinder und Tragarmen, die die Tragzapfen des Tragrahmens tragen, in dem sich das Gleßrohr befindet, wobei die Wechseleinrichtung ebenfalls am Rahmen der Verschlussplatte befestigt ist und sich somit synchron mit dieser bewegt. Der Zylinder fungiert als Spanneinrichtung zum Anpressen des Gießrohrs an die verschiebbare Verschlussplatte.The JP 07 016739 A shows a device for replacing and closing of pouring tubes to a spout of a melt container with a closure attached to the melt container slide closure, which consists of a fixed and relative to this sliding closure plate, which is held in a sliding frame, which is actuated by a displacement drive and the pouring tube wearing.

The changing device consists of cylinder and support arms which carry the support pins of the support frame, in which the Gleßrohr is, wherein the changing device is also attached to the frame of the closure plate and thus moves synchronously with this. The cylinder acts as a clamping device for pressing the pouring tube to the sliding closure plate.

Die verschiebbare Verschlussplatte kann sich sowohl in einer "Offen-Position", die den Durchtritt von Metallschmelze ermöglicht, als auch in einer "Geschlossen-Position", die den Durchtritt von Metallschmelze sperrt, befinden.The displaceable closure plate consists essentially of a closure plate frame, which receives in a recess a closure plate insert made of a refractory material with a passage opening for the liquid metal. The closure plate frame is guided horizontally movable in a support frame of the slide closure and coupled with a displacement drive which is fixed to the support frame of the slide closure. By attaching the changing device for the pouring tube and, depending on the embodiment, an arbitrarily designed clamping device for pressing the pouring tube on this closure plate, in particular on the closure plate frame of the closure plate, an accurate positioning of the pouring tube is guaranteed regardless of the current position of the sliding closure plate sure. The slidable closure plate can be in both an "open position" that allows the passage of molten metal and in a "closed position" that blocks the passage of molten metal.

Erfindungsgemäß umfasst die Wechseleinrichtung eine Schwenkwelle und einen mit der Schwenkwelle verbundenen Schwenkantrieb. Die Schenkwelle ist an der verschiebbaren Verschlussplatte abgestützt, die eine Schwenkbewegung um ihre Schwenkachse zulässt. Weiters ist eine Aufnahmegabel zur Aufnahme des Gießrohres fest mit der Schwenkwelle verbunden und die beiden Gabelarme der Aufnahmegabel sind in parallelen Normalebenen zur Schwenkachse angeordnet. Damit kann mit einer Drehbewegung bei kurzen Gabelarmen ein vollständiges Ausschwenken des Gießrohres aus dem Bereich des Verschlussplatteneinsatzes erreicht werden, wodurch der Verschlussplatteneinsatz zugänglich ist. Beispielsweise kann in dieser ausgeschwenkten Position des Gießrohres in einfacher Weise ein verstopfter Flüssigmetallkanal mit einer von einem Manipulator oder Roboter bewegten Sauerstofflanze freigeblasen werden.According to the invention, the changing device comprises a pivot shaft and a pivot drive connected to the pivot shaft. The rocker shaft is supported on the sliding closure plate, which allows a pivoting movement about its pivot axis. Furthermore, a recording fork for Recording of the pouring tube fixedly connected to the pivot shaft and the two fork arms of the receiving fork are arranged in parallel normal planes to the pivot axis. Thus, a complete pivoting of the pouring tube from the region of the closure plate insert can be achieved with a rotary movement with short fork arms, whereby the closure plate insert is accessible. For example, in this swung-out position of the pouring tube, a clogged liquid metal channel can be easily blown away with an oxygen lance moved by a manipulator or robot.

Eine geometrisch zweckmäßige Anordnung der Wechseleinrichtung auf der verschiebbaren Verschlussplatte bzw. dem Verschlussplattenrahmen ist gegeben, wenn die Schwenkachse der Schwenkwelle in einem seitlichen Abstand von dem Anschlussring für das Gießrohr angeordnet ist und das an den Anschlussring andockende Gießrohr eine Anschlussposition am Schieberverschluss festlegt und dass in Bezug auf eine die Schwenkachse aufnehmende Vertikalebene die Anschlussposition des Gießrohres auf einer Seite der Vertikalebene und eine Wechselposition für das Gießrohr auf der gegenüber liegenden abgewandten Seite der Vertikalebene oder unmittelbar in dieser Vertikalebene festgelegt ist.A geometrically expedient arrangement of the changing device on the sliding closure plate or the closure plate frame is given if the pivot axis of the pivot shaft is arranged at a lateral distance from the connection ring for the pouring tube and the casting tube docking to the connection ring defines a connection position on the slide closure and that with respect is fixed to a pivot axis receiving the vertical plane, the connection position of the pouring tube on one side of the vertical plane and a change position for the pouring tube on the opposite opposite side of the vertical plane or directly in this vertical plane.

Eine Wechseleinrichtung der beschriebenen Bauart lässt eine Verlagerung des Gießrohres zwischen einer Anschlussposition an der verschiebbaren Verschlussplatte und einer Wechselposition des Gießrohres um eine Schwenkachse in einem Schwenkwinkelbereich zwischen 90° und 180° zu. Durch diese Ausschwenkbewegung wird die Gießdüse in einen für einen Manipulator leicht zugänglichen Bereich verbracht, sodass bei entsprechend günstiger Ausgestaltung des Aufnahmehakens an den Enden der Gabelarme sowohl der große Schwenkwinkel problemlos bewältigt werden kann als auch eine automatisierte Ent-und Beladung der Wechseleinrichtung durch einen Roboter leicht durchgeführt werden kann.A change device of the described type allows a displacement of the pouring tube between a connection position on the displaceable closure plate and a change position of the pouring tube about a pivot axis in a pivoting angle range between 90 ° and 180 °. By this Ausschwenkbewegung the casting nozzle is spent in a readily accessible to a manipulator area, so that with a correspondingly favorable design of the receiving hook at the ends of the fork arms both the large tilt angle can be easily handled as well as an automated unloading and loading of the changing device by a robot easily can be carried out.

Um einen automatisierten Wechsel des Gießrohres mit einem Roboter oder sonstigen Manipulator durchführen zu können, ist das Gießrohr mit einem Tragring ausgestattet und mit diesem in die Schwenkeinrichtung eingesetzt. Hierbei weist der Tragring ein auf den äußeren Gießrohrdurchmesser abgestimmtes Ringelement auf, in dem das Gießrohr steckt, an dem Ringelement schließen gegenüberliegende und voneinander weggerichtete Tragzapfen an, die in Aufnahmegabeln der beiden Gabelarme der Schwenkeinrichtung aufliegen und am Ringelement ist eine Kuppelvorrichtung für das Greifwerkzeug eines Roboters angeordnet. Zweckmäßig ist die Kuppelvorrichtung unter einem Winkel von 90° zu den Tragzapfen am Ringelement positioniert.In order to perform an automated change of the pouring tube with a robot or other manipulator, the pouring tube is equipped with a support ring and used with this in the pivoting device. Here, the support ring has a tuned to the outer shroud diameter ring element in which the shroud is inserted, on the ring member close opposite and directed away from each other support journals which rest in receiving forks of the two fork arms of the pivoting device and the ring member is a coupling device for the gripping tool Robot arranged. Suitably, the coupling device is positioned at an angle of 90 ° to the support pin on the ring member.

Nach dem Verschwenken des Gießrohres von der Anschlussposition in die Wechselposition kann der Roboter daher auf einfache Art ein zu wechselndes Gießrohr mit der ihm entgegen gerichteten Kuppelvorrichtung des Tragringes erfassen und daran andocken. Dann fädelt der Roboter das Gießrohr aus der Schwenkeinrichtung und stellt das Gießrohr in einem Werkzeugmagazin ab. Der Roboter ergreift ein für den nächsten Einsatz vorbereitetes Gießrohr aus dem Werkzeugmagazin mit seinem Greifwerkzeug an der Kuppelvorrichtung des Tragringes und hängt das Gierohr in die in der Wechselposition wartenden Aufnahmegabeln der Wechseleinrichtung. Anschließend wird das Gießrohr durch eine Schwenkbewegung wieder in die Anschlussposition verschwenkt und ist einsatzbereit.After pivoting the pouring tube from the connection position to the change position, the robot can therefore easily detect a pouring tube to be changed with the coupling device of the supporting ring directed against it and dock it thereto. Then the robot threads the pouring tube out of the swiveling device and places the pouring tube in a tool magazine. The robot takes a prepared for the next use pouring spout from the tool magazine with his gripping tool on the coupling device of the support ring and hangs the yaw tube in the waiting in the change position receiving forks the change device. Subsequently, the pouring tube is pivoted by a pivoting movement back into the connection position and is ready for use.

Vorzugsweise ist der Schwenkantrieb von einem Schwenkmotor gebildet. Schwenkmotoren ermöglichen eine genaue Drehwinkeleinstellung der Schwenkwelle und damit ein präzises Ansteuern der Anschlussposition, der Wechselposition und gegebenenfalls notwendiger Zwischenpositionen des Gießrohres.Preferably, the pivot drive is formed by a pivot motor. Swivel motors allow accurate rotation angle adjustment of the pivot shaft and thus precise control of the connection position, the change position and possibly necessary intermediate positions of the pouring tube.

Bevorzugt wird ein hydraulischer Schwenkmotor eingesetzt. Aber auch Schwenkmotoren mit pneumatischem oder elektrischem Antrieb können gleichermaßen verwendet werden. Der vorzugsweise hydraulische Schwenkmotor umfasst einen Linearzylinder und ein Getriebe zur Erzeugung einer Schwenkbewegung der Wechseleinrichtung unter vorbestimmten Schwenkbedingungen.Preferably, a hydraulic swing motor is used. But also swivel motors with pneumatic or electric drive can be used equally. The preferably hydraulic swing motor comprises a linear cylinder and a gear for generating a pivoting movement of the changing device under predetermined pivoting conditions.

Zweckmäßig ist die Spannvorrichtung zum Anpressen des Gießrohres an den Anschlussring mit einem vorbestimmten Anpressdruck an der verschiebbaren Verschlussplatte befestigt.Suitably, the clamping device for pressing the pouring tube is attached to the connection ring with a predetermined contact pressure on the sliding closure plate.

Alternativ besteht auch die Möglichkeit, dass die Spannvorrichtung zum Anpressen des Gießrohres an den Anschlussring unmittelbar in die Wechseleinrichtung, insbesondere den Schwenkantrieb, integriert ist.Alternatively, there is also the possibility that the clamping device for pressing the pouring tube to the connecting ring is integrated directly into the changing device, in particular the pivot drive.

Vorzugsweise ist der Spanneinrichtung eine Regeleinrichtung zur geregelten Einstellung eines vorbestimmten Anpressdruckes zugeordnet.Preferably, the clamping device is associated with a control device for the controlled setting of a predetermined contact pressure.

Falls die Spanneinrichtung unmittelbar in den hydraulischen Schwenkmotor integriert ist, bzw. teil des hydraulischen Schwenkmotors ist, wird mit den hydraulischen Einrichtungen des Schwenkmotors der geregelte Anpressdruck eingestellt. In diesem Fall ist die Spannvorrichtung nur indirekt an der verschiebbaren Verschlussplatte bzw. dem Verschlussplattenrahmen angeordnet.If the clamping device is integrated directly into the hydraulic swing motor, or is part of the hydraulic swing motor, the regulated contact pressure is set with the hydraulic devices of the swing motor. In this case, the clamping device is arranged only indirectly on the sliding closure plate or the closure plate frame.

Die Spanneinrichtung kann auch von einer auf die Schwenkwelle der Schwenkeinrichtung einwirkenden vorgespannten Feder gebildet sein. Die vorgespannte Feder kann durch eine mechanische Feder beliebiger Bauart, z.B. eine Drehfeder, einem pneumatischen oder hydraulischen Federelement gebildet sein.The tensioning device can also be formed by a prestressed spring acting on the pivot shaft of the pivoting device. The prestressed spring may be replaced by a mechanical spring of any type, e.g. a torsion spring, a pneumatic or hydraulic spring element may be formed.

Der mit einem Schieberverschluss verschlossene und mit Metallschmelze gefüllte Schmelzenbehälter durchläuft, sofern es sich um eine Gießpfanne handelt, im metallurgischen Betrieb zumeist mehrere Behandlungsstufen in denen die Metallschmelze beispielsweise legiert oder einem metallurgischen Feinungsvorgang unterzogen wird. Hierbei sollen außer dem Schieberverschluss selbst keine weiteren Bauteile am Behälterboden befestigt sein, vor allem auch keine hydraulischen Stelleinrichtungen. Um dies auch bei der erfindungsgemäßen Wechseleinrichtung umsetzen zu können, umfasst die Wechseleinrichtung, in teilbare Baugruppen gliederbar, eine Schwenkwelle und einen an die Schwenkwelle während einer Einsetzbewegung selbsttätig ankuppelbaren Schwenkantrieb. An der verschiebbaren Verschlussplatte oder konkret am verschiebbaren Verschlussplattenrahmen ist zumindest eine Zentriernase für die Aufnahme und Lagepositionierung des Schwenkantriebes angeordnet. Das Einsetzen und Ankuppeln des Schwenkantriebes an die Schwenkwelle erfolgt zweckmäßig mit einem Roboter.The sealed with a slide valve closure and filled with molten metal melt container, if it is a ladle, in metallurgical operation usually several treatment stages in which the molten metal, for example, alloyed or subjected to a metallurgical refining process. In this case, no further components should be attached to the bottom of the container except the slide valve itself, above all, no hydraulic actuators. In order to be able to implement this also in the changing device according to the invention, the changing device comprises, articulated in divisible assemblies, a pivot shaft and an automatically engageable on the pivot shaft during an insertion pivot actuator. At least one centering lug for receiving and position positioning of the pivoting drive is arranged on the displaceable closure plate or concretely on the displaceable closure plate frame. The insertion and coupling of the pivot drive to the pivot shaft is advantageously carried out with a robot.

Die gleiche Möglichkeit besteht auch für Die Schwenkwelle, die mit ihren Lagern in Aufnahmetaschen an der verschiebbaren Verschlussplatte oder dem verschiebbaren Verschlussplattenrahmen eingesetzt, lagepositioniert und verriegelt werden kann. Auch hier erfolgt das Einsetzen zweckmäßig mit einem Roboter.The same possibility also exists for the pivot shaft, which can be positioned, locked and positioned with its bearings in receiving pockets on the sliding closure plate or the sliding closure plate frame. Again, the insertion is done appropriately with a robot.

Zur Erleichterung dieser automatisierten Montagearbeiten sind der Schwenkantrieb und gegebenenfalls auch die Schwenkwelle mit einer Kuppelvorrichtung für ein Greifwerkzeug eines Roboters ausgerüstet. Damit wird die Aufnahme oder Ablage dieser Baugruppen von oder auf einer vorbereiteten Tragkonsole einfach durchzuführen. Damit wird es auch ohne Personaleinsatz in einem potentiellen Gefahrenbereich möglich, dass der Schwenkantrieb und/oder die Schwenkwelle während einzelner Vorbehandlungsschritte und während des Transportes des Schmelzenbehälters im metallurgischen Betrieb von der verschiebbaren Verschlussplatte oder dem verschiebbaren Verschlussplattenrahmen getrennt auf einem die Gießposition bestimmenden Traggerüst auf einer Tragkonsole abgelegt sind und der Schwenkantrieb und/oder die Schwenkwelle erst nach dem Absetzen des Schmelzenbehälters auf dem Traggerüst mit einem Roboter oder einem sonstigen Manipulator an der verschiebbaren Verschlussplatte oder dem verschiebbaren Verschlussplattenrahmen eingesetzt wird.To facilitate this automated assembly work, the pivot drive and possibly also the pivot shaft are equipped with a coupling device for a gripping tool of a robot. Thus, the recording or filing of these modules from or on a prepared support bracket is easy to perform. Thus, it is possible even without staff in a potential danger area that the pivot drive and / or the pivot shaft during individual pretreatment steps and during the Transportation of the melt container in metallurgical operation of the sliding closure plate or the sliding shutter plate frame are stored separately on a support frame determining the casting position on a support bracket and the pivot drive and / or the pivot shaft only after settling of the melt container on the support frame with a robot or other manipulator is used on the sliding closure plate or the sliding closure plate frame.

Für den konkreten Anwendungsfall bei einer Stranggießanlage bildet der Schmelzenbehälter eine Gießpfanne, mit der aus dem Stahlwerk vorbehandelte Stahlschmelze an die Stranggießanlage gebracht wird. Das Traggerüst zur Aufnahme der Gießpfanne bildet der Pfannendrehturm mit seinen Gabelarmen. Auf dem Pfannendrehturm befindet sich auch die Tragkonsole, auf der der Schwenkantrieb und die Schwenkwelle für die robotergestützte Montage am Schieberverschluss vorbereitet sind.For the specific application in a continuous casting plant, the melt container forms a ladle, with the steel melt pretreated from the steel mill is brought to the continuous casting. The support frame for receiving the ladle forms the Pfannendrehurm with his fork arms. On the ladle turret is also the support bracket on which the rotary actuator and the pivot shaft for the robot-mounted mounting on slide gate valve are prepared.

Ausführung der ErfindungEmbodiment of the invention

Die erfindungsgemäße Vorrichtung zum auswechselbaren Anschließen eines Gießrohres an einen Ausguss eines Schmelzenbehälters ist in den Figuren 1 bis 4 in mehreren Ansichten schematisch dargestellt und nachfolgend anhand dieses Ausführungsbeispiels im Detail erläutert.The inventive device for interchangeable connection of a pouring tube to a spout of a melt container is in the FIGS. 1 to 4 schematically illustrated in several views and explained below with reference to this embodiment in detail.

Bei Verteilergefäßen in Stranggießanlagen wird ausgussseitig üblicherweise von Gießrohren oder Tauchgießrohren; bei Gießpfannen von Schattenrohren gesprochen. Die erfindungsgemäße Lösung umfasst beide Anwendungen und ist für beide Anwendungen gleichermaßen geeignet.In distribution vessels in continuous casting is usually on the spout of pouring pipes or Tauchgießrohren; spoken by ladles of shadow tubes. The solution according to the invention comprises both applications and is equally suitable for both applications.

Figur 3 zeigt in einem Teilschnitt einen Schmelzenbehälter 1, mit einem Stahlmantel 1a und einer innen anliegenden feuerfesten Auskleidung 1b. Der Schmelzenbehälter kann beispielsweise als Gießpfanne oder als Zwischengefäß an einer Stranggießanlage ausgebildet sein. Im Boden des Schmelzenbehälters ist ein aus feuerfestem Material gemauerter Ausguss 2 mit einer Austrittsöffnung 2a zum kontinuierlichen Ausströmen von Metallschmelze (z.B. flüssiger Stahl) angeordnet. An der Außenseite des Schmelzenbehälters ist ein als Schieberverschluss 3 ausgebildetes Verschlussorgan angeordnet, mit dem die Austrittsöffnung 2a geschlossen oder geöffnet oder die Menge der durchströmenden Metallschmelze geregelt werden kann. FIG. 3 shows in a partial section a melt container 1, with a steel shell 1a and an inner refractory lining 1b. The melt container may be formed, for example, as a ladle or as an intermediate vessel on a continuous casting. In the bottom of the melting container, a spout 2 made of refractory material is arranged with an outlet opening 2a for the continuous outflow of molten metal (eg liquid steel). On the outside of the melt container, a closure member designed as a slide closure 3 is arranged, with which the outlet opening 2a can be closed or opened or the amount of molten metal flowing through can be regulated.

Der Schieberverschluss 3 ist in Figur 2 als Zweiplattenschieber ausgebildet. Der Schieberverschluss umfasst - funktional betrachtet - eine festliegende Verschlussplatte 4 und eine verschiebbare Verschlussplatte 5. Im Rahmen der Erfindung kann sowohl die festliegende Verschlussplatte als auch die verschiebbare Verschlussplatte aus mehreren Teilen bestehen, z.B. jeweils mehrere aufeinander liegende Verschlussplatten umfassen.The slide closure 3 is in FIG. 2 designed as a two-plate slide. The slide closure comprises - seen functionally - a fixed closure plate 4 and a sliding closure plate 5. In the invention, both the fixed closure plate and the sliding closure plate consist of several parts, for example, each comprise a plurality of superimposed closure plates.

Die festliegende Verschlussplatte 4 umfasst einen Verschlussplattenrahmen 6, der unmittelbar am Stahlmantel 1a des Schmelzenbehälters 1 durch eine Schraubverbindung befestigt ist. Ein feuerfester Verschlussplatteneinsatz 7 ist in den Verschlussplattenrahmen 6 eingesetzt und weist eine Durchtrittsöffnung 8 auf, die mit der Austrittsöffnung 2a im Schmelzenbehälter 1 fluchtet. An der festliegenden Verschlussplatte 4 anliegend ist die verschiebbare Verschlussplatte 5 angeordnet, die ebenfalls ein Verschlussplattenrahmen 9 umfasst, der an nicht näher dargestellten Horizontalführungen der festliegenden Verschlussplatte 4 zwischen zwei Stellpositionen verlagerbar angeordnet ist. In den bewegbaren Verschlussplattenrahmen 9 ist ein Verschlussplatteneinsatz 10 eingesetzt und abgestützt, der in einer der beiden Stellposition eine mit der Durchtrittsöffnung 8 im Verschlussplatteneinsatz 7 fluchtende Durchtrittsöffnung 11 aufweist und der in der weiteren Stellposition die Durchtrittsöffnung 11 sperrt. Die verschiebbare Verschlussplatte 5 ist mit einem hydraulischen Stellglied 12, beispielsweise einem ansteuerbaren Druckmittelzylinder, gelenkig verbunden, wobei das Stellglied 12 am festliegenden Verschlussplattenrahmen 6 abgestützt ist und die verschiebbare Verschlussplatte 5 zwischen den beiden Stellpositionen verschiebt.The fixed closure plate 4 comprises a closure plate frame 6, which is fastened directly to the steel jacket 1a of the melt container 1 by a screw connection. A refractory closure plate insert 7 is inserted into the closure plate frame 6 and has a passage opening 8, which is aligned with the outlet opening 2a in the melt container 1. Adjacent to the fixed closure plate 4, the displaceable closure plate 5 is arranged, which also comprises a closure plate frame 9, which is not shown on horizontal guides of the fixed Closing plate 4 is arranged displaceable between two parking positions. In the movable closure plate frame 9, a closure plate insert 10 is inserted and supported, which in one of the two actuating position has an aligned with the passage opening 8 in the closure plate insert 7 through opening 11 and which blocks the passage opening 11 in the other setting position. The displaceable closure plate 5 is pivotally connected to a hydraulic actuator 12, for example a controllable pressure cylinder, wherein the actuator 12 is supported on the fixed closure plate frame 6 and shifts the sliding closure plate 5 between the two setting positions.

Der Verschlussplatteneinsatz 10 der verschiebbaren Verschlussplatte 5 weist einen Anschlussring 13 auf, der ein Teil des Verschlussplatteneinsatzes 10 sein kann oder aber auch als getrennter gießdüsenartige Bauteil 13a, wie in Figur 2 dargestellt, der verschiebbaren Verschlussplatte 5 zugeordnet ist. Dieser Anschlussring 13 oder der gießdüsenartige Bauteil 13a dient der Aufnahme des Gießrohres 14 und dessen Zentrierung in einem konischen Aufnahmesitz.The closure plate insert 10 of the displaceable closure plate 5 has a connection ring 13 which may be part of the closure plate insert 10 or else as a separate pouring nozzle-like component 13a, as in FIG FIG. 2 represented, the sliding closure plate 5 is assigned. This connection ring 13 or the pouring nozzle-like component 13a serves to receive the pouring tube 14 and its centering in a conical receiving seat.

Zur Manipulation des Gießrohres 14, vorzugsweise seines Wechsels infolge Verschleißes, ist eine Wechseleinrichtung 16 vorgesehen mit der das Gießrohr 14 von einer Wechselposition A in eine Anschlussposition B und zurück transportiert werden kann. Die Wechseleinrichtung 16 ist zur Gänze ortsfest auf dem Verschlussplattenrahmen 9 der verschiebbaren Verschlussplatte 5 befestigt und daher synchron mit dieser Verschlussplatte verlagerbar. Daraus ergibt sich ein wesentlicher Vorteil einer solcherart auf der beweglichen Verschlussplatte 5 positionierten Wechseleinrichtung 16. Der relative Transportweg für die Gießrohrmanipulation bleibt unabhängig von der augenblicklichen Position der verschiebbaren Verschlussplatte (offene oder geschlossene Position) stets gleich und das zentrische Aufsetzen des Gierohres auf dem Anschlussring 13 ist stets sicher gewährleistet und einfach durchführbar (Figuren 1, 2).For manipulation of the pouring tube 14, preferably its change due to wear, a changing device 16 is provided with the pouring tube 14 can be transported from a change position A in a connection position B and back. The changing device 16 is completely fixedly mounted on the closure plate frame 9 of the sliding closure plate 5 and therefore displaced synchronously with this closure plate. This results in a significant advantage of such a kind on the movable closure plate 5 positioned change device 16. The relative transport for the Gießrohrmanipulation remains regardless of the instantaneous position of the sliding closure plate (open or closed position) always the same and the centric placement of the yaw tube on the connecting ring thirteenth is always safe and easy to carry out ( FIGS. 1 . 2 ).

Wie sich aus den Figuren 1, 3 und 4 ergibt, umfasst die Wechseleinrichtung 16 einen Schenkantrieb 17 und eine Schwenkwelle 18. Die Schwenkwelle 18 ist - eine Schwenkbewegung um ihre Schwenkachse 19 zulassend - direkt mit dem motorischen Schwenkantrieb 17 gekuppelt und über Lager 20 drehbar auf der verschiebbaren Verschlussplatte 5 abgestützt. Das freie Ende der Schwenkwelle 18 mündet in eine Aufnahmegabel 21 mit zwei Gabelarmen 22a, 22b zur Aufnahme des Gießrohres 14, wobei die Gabelarme in einem Abstand zueinander in parallelen Normalebenen zur Schwenkachse 19 angeordnet sind. Der Abstand der Gabelarme 22a, 22b orientiert sich am äußeren Durchmesser des Gießrohres 14. Die Gabelarme 22a, 22b verlaufen hakenförmig und bilden Aufnahmetaschen 23 zur Aufnahme des Gießrohres 14. Die Aufnahmetaschen 23 sind hierbei so ausgebildet, dass das Gießrohr 14 während der gesamten Schwenkbewegung zwischen der Anstellposition B und der Wechselposition A und zurück nicht aus den Aufnahmetaschen rutschen kann und dass speziell in der Anstellposition A die Übertragung eines Anpressdruckes vom Gießrohr 14 auf den Anschlussring 13 sicher gewährleistet ist.As is clear from the FIGS. 1 . 3 and 4 results, the changing device 16 comprises a Schenk drive 17 and a pivot shaft 18. The pivot shaft 18 - a pivoting movement about its pivot axis 19 permitting - directly coupled to the motorized pivot drive 17 and rotatably supported by bearings 20 on the sliding closure plate 5. The free end of the pivot shaft 18 opens into a receiving fork 21 with two fork arms 22 a, 22 b for receiving the pouring tube 14, wherein the fork arms at a distance from each other in parallel normal planes to Pivot axis 19 are arranged. The distance between the fork arms 22a, 22b is based on the outer diameter of the pouring tube 14. The fork arms 22a, 22b are hook-shaped and form receiving pockets 23 for receiving the pouring tube 14. The receiving pockets 23 are here designed so that the pouring tube 14 during the entire pivoting movement between the Anstellposition B and the change position A and back can not slip out of the receiving pockets and that especially in the setting position A, the transmission of a contact pressure from the pouring tube 14 is securely ensured on the connecting ring 13.

Die Wechseleinrichtung 16 ist mit seiner Schwenkwelle 18 bzw. Schwenkachse 19 seitlich neben dem Schieberverschluss 3 und dem Anschlussring 13 angeordnet. In Bezug auf eine die Schenkachse 19 aufnehmende Vertikalebene C ist die Anschlussposition B des Gießrohres auf einer Seite der Vertikalebene und eine Wechselposition A für das Gießrohr auf der gegenüber liegenden abgewandten Seite der Vertikalebene C oder unmittelbar in dieser Vertikalebene festgelegt. Die Schwenkachse 19 ist parallel zur Verschieberichtung der verschiebbaren Verschlussplatte 5 ausgerichtet. Mit relativ kurzen Gabelarmen 22a, 22b kann das Gießrohr 14 von der Anschlussposition B in die relativ leicht zugängliche Wechselposition A verbracht werden, in der mit einem hier nicht dargestellten Manipulator oder einem Roboter das Gießrohr aus den Aufnahmetaschen 23 der Gabelarme leicht entnommen und eine Austauschgießrohr wieder eingesetzt werden kann. Weiters ist der Ausgießbereich für Reinigungsarbeiten, z.B. einem Aufbrennen der Austrittsöffnung mit einer ebenfalls von einem Roboter oder sonstigem Manipulator bewegten Sauerstoffblaslanze oder einer anderen Einrichtung zum Öffnen oder Reinigen der Austrittsöffnung leicht zugänglich gemacht. Der Schwenkwinkelbereich α zwischen der Aufnahmeposition B und der Wechselposition A liegt bei etwa 180°.The changing device 16 is arranged with its pivot shaft 18 or pivot axis 19 laterally next to the slide closure 3 and the connecting ring 13. With regard to a vertical plane C receiving the pivot axis 19, the connection position B of the pouring tube on one side of the vertical plane and a change position A for the pouring tube are defined on the opposite, opposite side of the vertical plane C or directly in this vertical plane. The pivot axis 19 is aligned parallel to the displacement direction of the sliding closure plate 5. With relatively short fork arms 22a, 22b, the pouring tube 14 can be moved from the connection position B in the relatively easily accessible change position A, in which removed easily with a manipulator or a robot, not shown here, the pouring tube 23 and the Ausschgetehre a Austauschgießrohr again can be used. Furthermore, the pouring area is for cleaning work, e.g. a burning of the outlet opening with an also moved by a robot or other manipulator oxygen blowing lance or other means for opening or cleaning the outlet opening made easily accessible. The pivot angle range α between the receiving position B and the change position A is about 180 °.

Das Gießrohr 14 ist in einen Tragring 25 eingesteckt und mit diesem in die beiden Aufnahmetaschen 23 der Gabelarme 22a, 22b eingesetzt. Es umfasst eine Ringelement 25a mit einem konischen Aufnahmesitz, der mit einem konischen Ringteil im oberen Bereich des Gießrohres 14 korrespondiert. An das Ringelement 25a schließen einander gegenüberliegende und voneinander weggerichtete Tragzapfen 25b an, die in den Aufnahmetaschen 23 der Wechseleinrichtung 16 aufliegen. Weiters umfasst das Ringelement eine Kuppelvorrichtung 25c, mit der eine Greifverbindung mit einem Roboter oder Manipulator hergestellt werden kann.The pouring tube 14 is inserted into a support ring 25 and used with this in the two receiving pockets 23 of the fork arms 22a, 22b. It comprises a ring element 25a with a conical receiving seat which corresponds to a conical ring part in the upper region of the pouring tube 14. The ring element 25a is adjoined by support journals 25b lying opposite one another and pointing away from one another and resting in the receiving pockets 23 of the exchange device 16. Furthermore, the ring element comprises a coupling device 25c, with which a gripping connection can be made with a robot or manipulator.

Der Schwenkantrieb 17 ist von einem Schwenkmotor 26 gebildet, der vorzugsweise hydraulisch betrieben ist. Dieser ermöglicht die direkte Umsetzung einer hydraulisch erzeugten Bewegung eines Linearzylinders mittels eines Getriebes in eine dosierte Drehbewegung der Schwenkwelle 18. Der hydraulische Schwenkmotor ermöglicht auch die Einstellung eines geregelten Anpressdruckes und das Halten dieses Anpressdruckes über einen Gießzyklus durch eine in ihn integrierte Spannvorrichtung 27.The pivot drive 17 is formed by a pivoting motor 26, which is preferably operated hydraulically. This allows the direct implementation of a hydraulically generated movement of a linear cylinder by means of a gear in a metered rotational movement of the pivot shaft 18. The hydraulic swing motor also allows the setting of a regulated contact pressure and maintaining this contact pressure over a casting cycle by a built-in clamping device 27th

Eine Spanneinrichtung 27 zum gezielten Anpressen des Gießrohres an die verschiebbare Verschlussplatte kann beispielsweise auch durch Einwirkung einer vorgespannten Feder 27a erreicht werden, die unmittelbar auf die Schenkwelle einwirkt. Diese vorspannbare Feder ist in Figur 4 als Drehfeder ausgebildet, umgreift die Schwenkwelle 18, ist an dieser und an der verschiebbaren Verschlussplatte 5, bzw. am Verschlussplattenrahmen 9 fixiert und baut während der Schwenkbewegung in die Anschlussposition b einen entsprechenden Anpressdruck auf.A tensioning device 27 for selectively pressing the pouring tube onto the displaceable closing plate can also be achieved, for example, by the action of a prestressed spring 27a, which acts directly on the feeding shaft.
