Description

Vorrichtung zur Steuerung eines Stopfens eines metallurgischen Gefäßes Device for controlling a stopper of a metallurgical vessel
Die Erfindung bezieht sich auf eine Vorrichtung zur Steuerung eines Stopfens eines metallurgischen Gefäßes, insbesondere einer Verteilerrinne einer Stranggießanlage, mit einem heb- und senkbaren Stopfen, welcher in einem relativ zum metall- urgischen Gefäß beweglichen Tragrahmen abgestützt ist, welcher lösbar mit dem metallurgischen Gefäß verriegelbar ist.The invention relates to a device for controlling a stopper of a metallurgical vessel, in particular a distribution channel of a continuous casting installation, with a liftable and lowerable stopper, which is supported in a support frame which is movable relative to the metallurgical vessel and which can be releasably locked to the metallurgical vessel is.
Eine Einrichtung der eingangs genannten Art ist beispielsweise der EP-Al-439 681 zu entnehmen. Bei dieser bekannten Ein- richtung ist zur regelbaren Verstellung eines Stopfens einer Verteilerinne der Stopfen an einer über der Verteilerrinne oder dem metallurgischen Gefäß angeordneten Traverse ange¬ schlossen. Diese Traverse ist ihrerseits mit einer in einer Vertikalführung auf- und abbewegbaren Tragstange verbunden, wobei die Vertikalführung der Tragstange als Rollenführung ausgebildet ist. Die bekannte Ausbildung ist an der Außenseite der Verteilerrinne festgelegt, so daß die Bewegbarkeit relativ zum metallurgischen Gefäß bzw. zur Verteilerrinne nur inner¬ halb der Führung an der Außenseite der Verteilerrinne bzw. des metallurgischen Gefäßes gegeben ist.A device of the type mentioned in the introduction can be found, for example, in EP-Al-439 681. In this known device, in order to adjust a stopper of a distributor channel in a controllable manner, the stopper is connected to a crossbar arranged above the distributor channel or the metallurgical vessel. This traverse is in turn connected to a support rod that can be moved up and down in a vertical guide, the vertical guide of the support rod being designed as a roller guide. The known design is fixed on the outside of the distribution channel, so that the mobility relative to the metallurgical vessel or to the distribution channel is only given within the guide on the outside of the distribution channel or the metallurgical vessel.
Aus einer Reihe weiterer Literaturstellen, wie insbesondere der EP-A2-435 540 sowie der DE-A 2 021 211 sind übliche An¬ ordnungen bekannt, bei welchen die Stopfenmechanik zur Rege- lung des ausfließenden Flüssigmetalls aus der Verteilerrinne einzeln an der Verteilerwanne befestigt ist. Die Stopfen¬ mechanik verbleibt beim Wechseln des Verteilers in angebauter Stellung.From a number of further references, such as in particular EP-A2-435 540 and DE-A 2 021 211, customary arrangements are known in which the stopper mechanism for regulating the liquid metal flowing out of the distributor trough is attached individually to the distributor trough . The stopper mechanism remains in the attached position when the distributor is changed.
Diese feste und starre Verbindung zwischen der Stopfenmechanik und der Verteilerwanne führt dazu, daß die Steuerung bzw. die Stopfstangen auch während einer Ausmauerungserneuerung der Verteilerwanne in der Regel nicht ausgebaut werden, da die fixe Befestigung an der Verteilerwanne eine zu umfangreiche und komplizierte Ausbauarbeit erfordert.This fixed and rigid connection between the plug mechanism and the distributor trough means that the control or the stuffing rods also during a refurbishment of the lining Distribution troughs are usually not removed, since the fixed attachment to the distribution trough requires too extensive and complicated removal work.
Die Stopfstange, die in der Regel an einem Ende mit einem Metallteil zwecks Befestigung an einem Haltegalgen und mit einem zur Kühlung dienenden Kanal ausgestattet ist, wird nach einer vorbestimmten Anzahl von Wannenentleerungen abge¬ schlagen, da sie einerseits verbraucht ist und andererseits eine zerstörungsfreie Abnahme mit relativ großem Aufwand ver¬ bunden wäre. In diesem Zusammenhang sind weiters bereits Schwenkmechanismen vorgeschlagen worden, welche sich aber gleichfalls nicht durchgesetzt haben.The stuffing rod, which is usually equipped at one end with a metal part for attachment to a holding boom and with a channel used for cooling, is knocked off after a predetermined number of trough empties, since on the one hand it is used up and on the other hand it is used for non-destructive removal would be connected with a relatively large outlay. In this context, swivel mechanisms have also already been proposed, but these have also not become established.
Die Erfindung zielt nun darauf ab, eine Vorrichtung der ein¬ gangs genannten Art zu schaffen, mit welcher eine Trennung der Stopfenmechanik vom metallurgischen Gefäß bzw. der Verteiler¬ rinne einer Stranggießanlage ohne hohen Bedienungsaufwand möglich ist und welche es ermöglicht, beispielsweise einen Verteilerwechsel vorzunehmen, ohne zu diesem Zweck die gesamte Stopfenmechanik abbauen zu müssen. Insbesondere für die Durch¬ führung von Ausmauerungsarbeiten zielt die erfindungsgemäße Ausbildung darauf ab, eine derartige Ausmauerungserneuerung ohne Beeinträchtigung durch die Stopfenmechanik zu ermög- liehen. Zur Lösung dieser Aufgabe ist die erfindungsgemäße Ausbildung im wesentlichen dadurch gekennzeichnet, daß der Tragrahmen für den heb- und senkbaren Stopfen quer zur Hubrichtung des Stopfens verschiebbar außerhalb des metallur¬ gischen Gefäßes abgestützt ist. Dadurch, daß ein gesonderter und gesondert vom metallurgischen Gefäß, insbesondere der Ver¬ teilerrinne, verschiebbarer Tragrahmen für den heb- und senkbaren Stopfen vorgesehen ist, wird es möglich, den Rahmen vom Verteiler zu trennen und auf diese Weise die Verteilerwanne beispielsweise mit einem Hebezeug frei wegzu- heben. Die einzelnen Stopfenführungen bzw. die Stopfenmechanik kann hiebei in einer jeweils die Bedienung nicht beein¬ trächtigenden verschobenen Position gehalten werden und steht unmittelbar nach Beendigung der Austauscharbeit mit vor¬ justierten Abständen für die einzelnen Stopfen wieder zur Verfügung. Dies ist insbesondere bei einer Ausbildung mit mehreren Stopfen von besonderer Bedeutung, da dadurch der War- tungsaufwand und der für den Wechsel einer Verteilerrinne er¬ forderliche Zeitaufwand wesentlich verringert werden kann. Dadurch, daß nun der Tragrahmen lösbar mit dem metallurgischen Gefäß verriegelbar ist, wird zum einen die Möglichkeit ge¬ schaffen für einen Verteilerwechsel den Rahmen vom metall- urgischen Gefäß bzw. Verteiler zu entriegeln und zum anderen in der Arbeitsstellung eine exakte und relativ toleranzfreie Betriebsweise sicherzustellen.The invention now aims to provide a device of the type mentioned at the outset with which the plug mechanism can be separated from the metallurgical vessel or the distributor trough of a continuous casting installation without high operating effort and which makes it possible, for example, to change the distributor, without having to dismantle the entire plug mechanism for this purpose. In particular for the implementation of brickwork, the design according to the invention aims to enable such a brickwork replacement without being affected by the plug mechanism. To achieve this object, the design according to the invention is essentially characterized in that the support frame for the liftable and lowerable stopper is slidably supported outside the metallurgical vessel transversely to the stroke direction of the stopper. The fact that a separate and separately movable from the metallurgical vessel, in particular the distribution channel, supporting frame for the lifting and lowering plug is provided, it is possible to separate the frame from the distributor and in this way free the distributor pan, for example with a hoist to lift away. The individual stopper guides or the stopper mechanism can be held and stand in a shifted position that does not affect the operation immediately after completion of the exchange work with pre-adjusted intervals for the individual plugs. This is particularly important in the case of a design with a plurality of plugs, since the maintenance effort and the time required for changing a distributor trough can thereby be significantly reduced. The fact that the support frame can now be releasably locked to the metallurgical vessel, on the one hand creates the possibility of unlocking the frame from the metallurgical vessel or distributor for a distributor change and, on the other hand, ensures an exact and relatively tolerance-free operating mode in the working position .
Mit Vorteil ist die erfindungsgemäße Ausbildung so getroffen, daß der Tragrahmen an einem außerhalb des metallurgischen Gefäßes verfahrbaren Portalrahmen abgestützt bzw. aufgehängt ist. Ein derartiger Portalrahmen kann einen oder mehrere Trag¬ rahmen für heb- oder senkbare Stopfen aufnehmen um auf diese Weise den raschen Anbau einer oder mehrerer Stopfenführungen an eine Verteilerwanne zu ermöglichen. Prinzipiell kann hiebei der Portalrahmen entweder stationär auf der Gießbühne oder beispielsweise mit dem Verteilerwagen mitfahrend montiert sein, wobei im Fall einer stationären Anordnung des Portal¬ rahmens naturgemäß das metallurgische Gefäß bzw. die Verteilerrinne in entsprechender Weise verfahrbar bzw. ver¬ schiebbar gelagert sein muß.The design according to the invention is advantageously made such that the supporting frame is supported or suspended from a portal frame which can be moved outside the metallurgical vessel. Such a portal frame can accommodate one or more support frames for lifting or lowering plugs in order in this way to enable the rapid attachment of one or more plug guides to a distribution trough. In principle, the portal frame can be mounted either stationary on the casting platform or, for example, traveling with the distribution trolley, whereby in the case of a stationary arrangement of the portal frame, the metallurgical vessel or the distribution channel must naturally be movable or displaceably mounted in a corresponding manner.
in besonders vorteilhafter Weise ist die erfindungsgemäße Aus¬ bildung dahingehend weitergebildet, daß der heb- und senkbare Stopfen bzw. der Tragrahmen desselben quer zur Verschiebe¬ richtung des Portalrahmens verschiebbar geführt ist. Mit einer derartigen Ausbildung kann eine hohe Flexibilität und Ver¬ schiebbarkeit bei stationärer Verlegung der Laufschiene für den Portalwagen erzielt werden. Wenn der Portalrahmen nach Art eines Wagens an einer Laufschiene verfahren werden kann, gelingt es, durch die Verschiebung des Tragrahmens relativ zum Portalrahmen in einfacher Weise, die gewünschte Justierung relativ zum metallurgischen Gefäß bzw. zur Verteilerrinne vorzunehmen. Mit Vorteil ist hiebei der Tragrahmen heb- und senkbar geführt.In a particularly advantageous manner, the training according to the invention is further developed in such a way that the plug which can be raised and lowered or the supporting frame thereof is guided so as to be displaceable transversely to the direction of displacement of the portal frame. With such a design, a high degree of flexibility and displaceability can be achieved when the running rail is laid stationary for the portal trolley. If the portal frame can be moved on a running rail in the manner of a carriage, the desired adjustment can be achieved in a simple manner by displacing the supporting frame relative to the portal frame relative to the metallurgical vessel or to the distribution channel. The support frame is advantageously guided so that it can be raised and lowered.
Um in der Betriebslage eine spielfreie und damit betriebs¬ sichere Funktion zu gewährleisten, um die Toleranzen zu ver¬ ringern, ist mit Vorteil die lösbare Verriegelung relativ zum metallurgischen Gefäß so ausgebildet, daß der Tragrahmen mit einem Kopplungsglied, insbesondere einer Klaue, ausgebildet ist, welches mit einem komplementären ausgebildeten Kopplungs¬ glied an der Außenseite des metallurgischen Gefäßes in der Betriebsposition des Stopfens zusammenwirkt. Eine derartige Klaue erfordert nur geringen konstruktiven Aufwand und das auf diese Weise an der Verteilerrinne bzw. am metallurgischen Gefäß anzuordnende Verriegelungsglied für den Eingriff der Klaue stellt keine wie immer geartete Behinderung bei Aus¬ mauerungsarbeiten dar. Im Gegenteil kann eine derartige Gegenverriegelung für den Abtransport der Verteilerrinne bzw. des metallurgischen Gefäßes zum Zweck der Vornahme von Ausmauerungsarbeiten durchaus dienlich sein.In order to ensure a play-free and thus operationally reliable function in the operating position in order to reduce the tolerances, the releasable locking relative to the metallurgical vessel is advantageously designed such that the support frame is designed with a coupling member, in particular a claw. which cooperates with a complementary coupling member on the outside of the metallurgical vessel in the operating position of the stopper. Such a claw requires little design effort and the locking member to be arranged in this way on the distribution channel or on the metallurgical vessel for the engagement of the claw does not constitute a hindrance of any kind in masonry work. On the contrary, such a counter-locking mechanism can be used to remove the Distribution channel or the metallurgical vessel may be useful for the purpose of carrying out brickwork.
In besonders einfacher Weise ist die Ausbildung so getroffen, daß an dem verfahrbaren Portalrahmen eine Mehrzahl von Trag¬ rahmen, insbesondere drei Tragrahmen, für heb- und senkbare Stopfen abgestützt sind, wobei durch den gemeinsamen Portal¬ rahmen der konstruktive Aufwand relativ gering gehalten werden kann.In a particularly simple manner, the design is such that a plurality of supporting frames, in particular three supporting frames, for lifting and lowering plugs are supported on the movable portal frame, the constructional effort being able to be kept relatively low by the common portal frame .
In besonders einfacher Weise können hiebei die Tragrahmen über einen gemeinsamen Antrieb, insbesondere Kettentrieb, relativ zum Portalrahmen heb- und senkbar sein.In a particularly simple manner, the supporting frames can be raised and lowered relative to the portal frame by means of a common drive, in particular a chain drive.
Die Erfindung wird nachfolgend an Hand von in der Zeichnung schematisch dargestellten Ausführungsbeispielen näher erläu- tert. In dieser zeigen Fig.l eine Ansicht einer ersten Aus¬ führungsform einer erfindungsgemäßen Vorrichtung zur Steuerung eines Stopfens eines metallurgischen Gefäßes in der Betriebs- bzw. Gießposition; Fig.2 in einer zu Fig.l ähnlichen Dar¬ stellung die Ausführungsform gemäß Fig.l in der Außer¬ betriebsstellung, in welcher eine Manipulation des metallurgischen Gefäßes bzw. der Verteilerwanne möglich ist; Fig.3 in vergrößertem Maßstab in einer zu Fig.l analogen Darstellung eine abgewandelte Ausführungsform einer erfin¬ dungsgemäßen Vorrichtung zur Steuerung eines Stopfens eines metallurgischen Gefäßes, wobei die Vorrichtung einen ver¬ fahrbaren Portalrahmen umfaßt; Fig.4 in einer zu Fig.2 analogen Darstellung die Außerbetriebsstellung der Vorrichtung gemäß Fig.3; und Fig.5 eine Rückansicht auf die Ausführungs¬ form gemäß den Fig.3 und 4.The invention is explained in more detail below on the basis of exemplary embodiments schematically illustrated in the drawing. 1 shows a view of a first embodiment of a device according to the invention for controlling a stopper of a metallurgical vessel in the operating or casting position; 2 shows, in a representation similar to FIG. 1, the embodiment according to FIG. 1 in the inoperative position, in which manipulation of the metallurgical vessel or the distributor trough is possible; 3 shows, on an enlarged scale, in a representation analogous to FIG. 1, a modified embodiment of a device according to the invention for controlling a stopper of a metallurgical vessel, the device comprising a movable portal frame; 4 shows, in a representation analogous to FIG. 2, the inoperative position of the device according to FIG. 3; and FIG. 5 shows a rear view of the embodiment according to FIGS. 3 and 4.
In den Fig.l und 2 ist mit 1 ein metallurgisches Gefäß, wie beispielsweise eine Verteilerrinne, bezeichnet, welches auf einer Gießbühne 2 gelagert ist. Die Gießbühne 2 kann dabei verfahrbar sein, wie dies schematisch durch Räder 3 angedeutet ist. Die Verteilerwanne weist in regelmäßigen Abständen Aus¬ gußöffnungen 4 auf, welche bei der in Fig.l dargestellten Gießposition durch einen Stopfen 5 verschlossen sind. Der Stopfen bzw. die Stopfenstange 5 weist in bekannter Weise einen im wesentlichen in Längssrichtung verlaufenden Kanal zur Kühlung auf, wie dies schematisch mit 6 angedeutet ist, und ist über einen Metallteil 7 an einem Haltegalgen 8 festlegbar. Dieser Haltegalgen 8 ist Teil einer allgemein mit 9 be¬ zeichneten Stopfenführung, welche in einem mit 10 bezeichneten Tragrahmen gelagert ist. Die Stopfenführung 9 mit dem Halte¬ galgen 8 ist für eine Auf- und Abwärtsbewegung der Stopfen¬ stange 5 im Sinne des Doppelpfeiles 11 in an sich bekannter Weise bewegbar.1 and 2, 1 denotes a metallurgical vessel, such as a distribution channel, which is mounted on a casting platform 2. The casting platform 2 can be moved, as is indicated schematically by wheels 3. The distributor trough has pouring openings 4 at regular intervals, which are closed by a stopper 5 in the pouring position shown in FIG. The stopper or stopper rod 5 has, in a known manner, an essentially longitudinal channel for cooling, as indicated schematically by 6, and can be fixed to a holding boom 8 via a metal part 7. This holding boom 8 is part of a stopper guide, generally designated 9, which is mounted in a support frame designated 10. The stopper guide 9 with the holding gallows 8 can be moved in a manner known per se for an upward and downward movement of the stopper rod 5 in the sense of the double arrow 11.
Wie aus den Fig.l und 2 ersichtlich, ist der Tragrahmen 10 für den Stopfen bzw. die Stopfenführung 9 an einer Führung 12 über eine entsprechende Halterung 13 gelagert, wobei über ein bei- spielsweise elektromechnisches Hebezeug 14 einerseits ein An¬ heben und Absenken des gesamten Tragrahmens 10 ebenfalls im Sinne des Doppelpfeiles 11 erfolgen kann und zusätzlich der gesamte Support bzw. das Hebezeug 14 im Sinne des Doppel¬ pfeiles 15 längs der Führung 12 verfahrbar ist. Derart gelingt es, wie dies insbesondere aus Fig.2 ersichtlich ist, die gesamte Stopfensteuerung sowie den Tragrahmen 10 für den Stopfen in einen Position zu bringen, in welcher das metal¬ lurgische Gefäß bzw. die Verteilerwanne 1 von der Position auf der Gießbühne ohne weiteres abgehoben werden kann, um bei¬ spielsweise Ausmauerungsarbeiten durchzuführen.As can be seen from FIGS. 1 and 2, the support frame 10 for the stopper or stopper guide 9 is supported on a guide 12 by means of a corresponding holder 13, with an elevating and lowering of the entire support frame 10 can also take place in the sense of the double arrow 11 and in addition the Entire support or the hoist 14 can be moved along the guide 12 in the sense of the double arrow 15. In this way, as can be seen in particular in FIG. 2, the entire stopper control and the support frame 10 for the stopper can be brought into a position in which the metallurgical vessel or the distributor trough 1 can easily be moved from the position on the casting platform can be lifted off, for example to carry out brickwork.
Im Gegensatz zu bekannten Ausführungen, bei welchen die Stopfensteuerung unmittelbar an der Verteilerrinne festgelegt war, ist somit bei der gezeigten Ausführungsform lediglich die Rinne zu entfernen, so daß durchzuführende Arbeiten an der Rinne bzw. am metallurgischen Gefäß ohne Behinderung und ohne Rücksichtnahme auf eine etwaige Stopfenführung bzw. Stopfenmechanik vorgenommen werden können.In contrast to known designs, in which the stopper control was fixed directly on the distributor trough, only the trough is to be removed in the embodiment shown, so that work to be carried out on the trough or on the metallurgical vessel without hindrance and without consideration of any stopper guidance or plug mechanism can be made.
Bei der in Fig.l und 2 gezeigten Ausführungsform ist somit der Tragrahmen 10 für die Stopfenführung 9 in einer auf die Bewe- gungsrichtung des Stopfens sowie der Stopfenmechanik im wesentlichen normale Richtung bewegbar, wobei die Justierung in der auf die Bewegungsrichtung, wie sie durch den Doppel¬ pfeil 15 angedeutet ist, normale Richtung, im Sinne der Längs¬ richtung der Verteilerrinne 1 durch eine Justierung der Ver- teilerrinne 1 auf der Gießbühne vorgenommen wird.In the embodiment shown in FIGS. 1 and 2, the support frame 10 for the stopper guide 9 can thus be moved in a direction which is essentially normal to the direction of movement of the stopper and the stopper mechanism, with the adjustment in the direction of movement as determined by the Double arrow 15 is indicated, normal direction, in the sense of the longitudinal direction of the distributor trough 1, is carried out by adjusting the distributor trough 1 on the casting platform.
Um eine korrekte Positionierung der Stopfenmechanik relativ zum metallurgischen Gefäß 1 im Gießbetrieb sicherzustellen, ist der Tragrahmen mit einer allgemein mit 16 bzeichneten Klemmvorrichtung ausgebildet, wobei die Klemmvorrichtung eine Klaue 17 umfaßt, welche mit einem entsprechend komplementär ausgebildeten Kopplungsglied 18 an der Außenseite des metal¬ lurgischen Gefäßes zusammenwirkt, um während des Betriebes eine korrekte und stabile Positionierung der Stopfenführung relativ zum metallurgischen Gefäß sicherzustellen. Es ist un¬ mittelbar ersichtlich, daß diese gegenseitige Kopplung leicht lösbar ist. Zusätzlich ist ein Handhebel 19 angedeutet, welcher eine hän¬ dische Betätigung des Galgens 8 der Stopfenführung ermöglicht.In order to ensure correct positioning of the stopper mechanism relative to the metallurgical vessel 1 in the casting operation, the supporting frame is designed with a clamping device, generally designated 16, the clamping device comprising a claw 17 which has a correspondingly complementary coupling member 18 on the outside of the metallurgical Vessel interacts to ensure correct and stable positioning of the stopper guide relative to the metallurgical vessel during operation. It is immediately apparent that this mutual coupling can be easily released. In addition, a hand lever 19 is indicated, which enables manual actuation of the gallows 8 of the stopper guide.
Bei der in den Fig.3 bis 5 dargestellten abgewandelten Aus- führungsform sind für gleiche Bauteile die Bezugszeichen der vorangehenden Ausführungsform beibehalten worden. Dabei ist ein metallurgisches Gefäß bzw. eine Verteilerwanne 1 im wesentlichen stationär auf einer wiederum mit 2 bezeichneten Gießbühne angeordnet und es ist in Fig.3 wiederum die Gie߬ bzw. Betriebsposition dargestellt, während in Fig.4 die Position der Stopfenführung bzw. des Tragrahmens desselben dargestellt ist, in welcher ein einfaches Entfernen der Verteilerrinne 1 ohne Behinderungen möglich ist. Die Öffnung 4 bei der Verteilerrinne 1 mündet in eine Kokille 20.In the modified embodiment shown in FIGS. 3 to 5, the reference numerals of the previous embodiment have been retained for the same components. In this case, a metallurgical vessel or a distribution trough 1 is arranged essentially stationary on a casting platform, again designated 2, and the casting or operating position is again shown in FIG. 3, while the position of the stopper guide or the support frame is shown in FIG the same is shown, in which a simple removal of the distribution channel 1 is possible without hindrance. The opening 4 at the distribution channel 1 opens into a mold 20.
Bei dieser Ausführungsform ist der Tragrahmen 10 für die Stopfenführung 9 bzw. den über den Haltegalgen 8 damit ver¬ bundenen Stopfen 5 in einem Portalwagen 21 gelagert, wobei dieser Portalwagen 21 über schematisch angedeutete Räder 22 auf einer Laufschiene 23 verfahrbar ist und somit im wesentlichen längs der Längserstreckung der Verteilerrinne 1 verschiebbar ist. Der Portalwagen 21 weist einer der orts¬ festen Führung 12 der vorangehenden Ausführungsform ent- sprechende Führung 24 auf, längs welcher wiederum über ein Hebezeug bzw. einen Support 14 der Tragrahmen 10 im Sinne des Doppelpfeiles 15 quer zur mit 11 angedeuteten Bewegungs¬ richtung des Stopfens bzw. der Stopfenführung verschiebbar ist. In der in Fig.3 dargestellten Betriebsposition ist der Tragrahmen 10 über die allgemein mit 16 bezeichnete Klemm¬ vorrichtung über die Klaue 17 an einem entsprechenden Kupp¬ lungsstück 18 an der Außenseite der Verteilerrinne 1 stabil festgelegt.In this embodiment, the support frame 10 for the plug guide 9 or the plug 5 connected thereto via the holding gallows 8 is mounted in a portal carriage 21, this portal carriage 21 being movable on a running rail 23 by means of schematically indicated wheels 22 and thus essentially longitudinally the longitudinal extent of the distribution channel 1 is displaceable. The portal trolley 21 has a guide 24 corresponding to the fixed guide 12 of the previous embodiment, along which, in turn, the lifting frame 10 in the sense of the double arrow 15 transversely to the direction of movement of the stopper indicated by 11 via a hoist or a support 14 or the plug guide is displaceable. In the operating position shown in FIG. 3, the support frame 10 is fixed in a stable manner by means of the clamping device, generally designated 16, via the claw 17 on a corresponding coupling piece 18 on the outside of the distributor channel 1.
Es ist weiters eine im oberen Bereich des Portalwagens 21 angedeutete Führung 25 dargestellt. Steuerketten für die Bewegung des Tragrahmens 10 im Portalrahmen sowie das Hebe und Senken der Stopfenführung sind mit 26 angedeutet.A guide 25 indicated in the upper area of the portal carriage 21 is also shown. Timing chains for the Movement of the support frame 10 in the portal frame and the lifting and lowering of the plug guide are indicated by 26.
Aus der Rückansicht gemäß Fig.5 ist ersichtlich, daß in de Portalwagen 21 drei an einem gemeinsamen Tragrahmen 10 ge lagerte Stopfenführungen 9 angeordnet sind, wobei der Trag rahmen 10 über einen schematisch angedeuteten Hebe- und Senk antrieb 27 angehoben und abgesenkt werden kann. Weiters sin die Führungen 24 am Portalwagen ersichtlich, wobei die Lage rung bzw. der Support an diesen wiederum allgemein mit 14 be zeichnet ist. Es können somit im Portalwagen 21 eine Mehrzah von Stopfenführungen exakt relativ zueinander positionier werden, so daß bei entsprechender Positionierung des Portal wagens durch ein Verfahren längs der Schiene 23 relativ z einem Verteilergef ß durch ein gleichzeitiges Absenken de Tragrahmens mehrere Stopfenführungen exakt justiert sind.From the rear view according to Figure 5 it can be seen that in the portal trolley 21 three ge on a common support frame 10 mounted plug guides 9 are arranged, the support frame 10 via a schematically indicated lifting and lowering drive 27 can be raised and lowered. Furthermore, the guides 24 on the gantry car can be seen, the position or the support on this in turn being generally designated with 14 be. A plurality of plug guides can thus be positioned exactly in relation to one another in the portal carriage 21, so that with appropriate positioning of the portal carriage by a method along the rail 23 relatively z a distributor vessel by a simultaneous lowering of the supporting frame, several plug guides are precisely adjusted.
Mit 28 sind Führungsrollen angedeutet, welche mit der Führun 25 im Bereich der Oberseite des Portalrahmens zusammenwirken.With 28 guide rollers are indicated, which cooperate with the guide 25 in the area of the top of the portal frame.
Es ist bei dieser Ausführungsform somit eine Bewegung de Stopfenführung 9 bzw. eines Stopfens 5 in im wesentlichen drei normal aufeinanderstehenden Richtungen ermöglicht, so daß eine exakte Positionierung relativ zu einem metallurgischen Gefäß 1 ohne weiteres möglich ist. In this embodiment, movement of the plug guide 9 or of a plug 5 in essentially three directions that are normal to one another is thus made possible, so that an exact positioning relative to a metallurgical vessel 1 is readily possible.
