Abstract

Bei einem Schiebeverschluss für den Ausguss metallurgischer Gefässe, insbesondere für Stahlgiesspfannen, mit Kipphebelanpressung der Schieberplatte an die Bodenplatte, soll durch Anordnung der Kipphebel (18,30) in Verstellrichtung des die Schieberplatte tragenden Gleitrahmens (12,32) die Anpresswirkung verbessert und ein kompakter Aufbau des Schiebeverschlusses erzielt werden.In the case of a slide closure for the pouring of metallurgical vessels, in particular for steel casting ladles, with rocker arm pressure of the slide plate against the base plate, the contact pressure is to be improved and a compact structure by arranging the rocker arms (18, 30) in the direction of adjustment of the slide frame (12, 32) carrying the slide plate of the slide lock can be achieved.

Description

Die Erfindung betrifft einen Schiebeverschluss für den Ausguss metallurgischer Gefässe, vorzugsweise Stahlgiesspfannen, mit einem Gehäuse und einem verstellbaren, eine Schieberplatte tragenden Gleitrahmen, der zwecks Anpressung der Schieberplatte an eine ortsfeste Bodenplatte entlang seiner Führungsbahnen von mit Federorganen belasteten und an einem Ende mit Auflagern besetzten Kipp-oder ähnlichen Hebeln abgestützt ist.The invention relates to a slide closure for the pouring of metallurgical vessels, preferably steel ladles, with a housing and an adjustable sliding frame carrying a slide plate, which, for the purpose of pressing the slide plate against a stationary base plate, is loaded along its guideways by spring elements and at one end with supports -or similar levers is supported.

Derartige Schiebeverschlüsse sind in Form eines Linearschiebeverschlusses beispielsweise aus der DE-AS 1 299 804 und in Form eines Drehschiebeverschlusses beispielsweise aus der DE-OS 22 12 312 bekannt. Beide Verschlüsse haben eine Anordnung mit quer zu der linearen bzw. bogenförmigen Verstellrichtung des Gleitrahmens gestellten Kipphebeln. Dadurch bedingt stehen die Hebel, die mit ihren Auflagerenden den die Schieberplatte tragenden Gleitrahmen an den Führungsbahnen untergreifen, mit ihren durch Federorgane belasteten Enden nach aussen weg, so dass sich infolge der aussenliegenden Hebellager und Federorgane eine sperrige Konstruktion mit relativ viel Platzbedarf ergibt, der am Einsatzort nur selten ausreichend zur Verfügung steht. Zudem weist die Kipphebelanordnung bezüglich der erforderlichen dichten, federnd nachgiebigen Anpressung der Schieberplatte an die Bodenplatte eine mangelhafte Stabilität auf.Such slide closures are known in the form of a linear slide lock, for example from DE-AS 1 299 804 and in the form of a rotary slide lock, for example from DE-OS 22 12 312. Both locks have an arrangement with rocker arms positioned transversely to the linear or arc-shaped adjustment direction of the slide frame. As a result, the levers, which engage with their support ends under the slide frame carrying the slide plate on the guideways, stand outwards with their ends loaded by spring elements, so that due to the external lever bearings and spring elements, a bulky construction with a relatively large amount of space is required, which on Location is rarely available. In addition, the rocker arm arrangement has inadequate stability with respect to the required tight, resilient pressure of the slide plate on the base plate.

Vorsorglich wird noch die nicht zum engeren Stand der Technik zählende AT-PS 359 664 angeführt, mit einem Linearschiebeverschluss, bei dem der Schieberplatten-Gleitrahmen auf Rollen zwischen zwei Wipprahmen geführt ist, die pendelbar je an einem abklappbaren Verschlusshebel gelagert sind. An den freien Enden der Verschlusshebel befinden sich Federpuffer und eine Querstrebe, wobei beim Spannen der Verschlusshebel gegen das Gehäuse mittels Schnellverschlüssen die Federpuffer eine Anpressung der Schieberplatte an die Bodenplatte bewirken. Auch hier ergeben die seitlich ausserhalb des Schieberplatten-Gleitrahmens vorgesehenen Wipprahmen eine relativ breite und hohe Bauweise des Schiebeverschlusses und ausserdem erfolgt die Anpressung, ausgehend von den an einer Stirnseite des Verschlusses untergebrachten Federpuffern, unsymmetrisch mittelbar über die Verschlusshebel, die starken Verwindungskräften ausgesetzt sind.As a precaution, AT-PS 359 664, which is not part of the narrower state of the art, is cited, with a linear sliding lock, in which the slide-plate sliding frame is guided on rollers between two rocker frames, each of which is pivotally mounted on a hinged locking lever. There are spring buffers and a cross strut on the free ends of the locking levers. When the locking levers are tensioned against the housing by means of quick-release fasteners, the spring buffers cause the slide plate to be pressed against the base plate. Here, too, the rocker frames provided on the side outside of the slide plate sliding frame result in a relatively wide and high construction of the slide lock and, in addition, the pressure is applied, starting from the spring buffers located on one end of the lock, asymmetrically indirectly via the lock levers, which are exposed to strong torsional forces.

Aufgabe der Erfindung ist es, bei einem gattungsgemässen Schiebeverschluss die federnde Abstützung des Gleitrahmens und damit die abdichtende Anpressung der Schieberplatte an die Bodenplatte zu verbessern, dies bei vereinfachtem Aufbau und platzsparenden Abmessungen des Schiebeverschlusses.The object of the invention is to improve the resilient support of the slide frame and thus the sealing pressure of the slide plate on the base plate in a generic slide closure, this with a simplified structure and space-saving dimensions of the slide closure.

Die gestellte Aufgabe wird gemäss der Erfindung dadurch gelöst, dass die Kipphebel in Richtung der Führungsbahnen bzw. längs des Verstellweges des Schieberplatten-Gleitrahmens mit dazu quer liegenden Kippachsen gemeinsam mit den Federorganen im Schiebeverschluss angeordnet sind. Auf diese Weise können die Kipphebel eine Stellung gegenüber den Führungsbahnen einnehmen, die bei in Betriebsstellung gebrachtem Gehäuse und damit verspanntem Gleitrahmen eine gleichmässige, federnd nachgiebige, in jeder Schliess- bzw. Öffnungsposition des Gleitrahmens optimal abdichtende Anpressung der Schieberplatte an die Bodenplatte gewährleistet. Darüberhinaus ergibt sich im Bereich Kipphebel/Gleitrahmen eine einfache, wartungsfreundliche und wenig schmutzanfällige Konstruktion mit platzsparendem Aufbau, was. wiederum eine kompakte Bauweise des Schiebeverschlusses ermöglicht.The object is achieved according to the invention in that the rocker arms are arranged together with the spring elements in the slide closure in the direction of the guide tracks or along the adjustment path of the slide plate sliding frame with tilt axes lying transversely thereto. In this way, the rocker arms can assume a position with respect to the guideways, which, when the housing is in the operating position and the tensioned slide frame is ensured, ensures a uniform, resilient pressure of the slide plate on the base plate that optimally seals in each closing or opening position of the slide frame. In addition, there is a simple, maintenance-friendly and less dirt-prone design with space-saving structure in the rocker arm / slide frame area. in turn enables a compact design of the sliding lock.

Dies gilt besonders für Schiebeverschlüsse mit abnehmbarem oder abschwenkbarem Gehausedeckel, in dem gemäss einem weiteren Merkmal der Erfindung Kipphebel und Federn angeordnet sind und wenigstens die Kipphebel unterhalb der Führungsbahnen liegen.This applies in particular to sliding closures with a removable or swiveling housing cover in which, according to a further feature of the invention, rocker arms and springs are arranged and at least the rocker arms lie below the guideways.

Diesbezüglich gilt für Schiebeverschlüsse mit linearer Verstellung eine besonders vorteilhafte Ausführung, nach der gemäss der Erfindung jeder der an den Längsseiten des Schieberplatten-Gleitrahmens vorgesehenen Führungsbahnen zwei Kipphebel einschliesslich Federorganen zugeordnet sind, wobei die Hebelenden mit den Auflagern gegeneinander symmetrisch zur Bodeplattenöffnung des Verschlusses bzw. zur Ausgussachse des metallurgischen Gefässes stehen und die Federorgane vorzugsweise im Gehäusedeckel ausserhalb des vom Gleitrahmen bestrichenen Hubweges untergebracht werden. Diese Konstruktion ist, infolge der symmetrischen Anpressung unmittelbar um die Bodenplattenöffnung herum, in Aufbau und Wirksamkeit hervorragend effizient.In this regard, a particularly advantageous embodiment applies to sliding locks with linear adjustment, according to which, according to the invention, two rocker arms, including spring members, are assigned to each of the guideways provided on the long sides of the slide plate sliding frame, the lever ends with the supports being symmetrical to one another to the bottom plate opening of the lock or to Spout axis of the metallurgical vessel and the spring members are preferably housed in the housing cover outside the stroke path covered by the sliding frame. Due to the symmetrical pressure directly around the base plate opening, this construction is extremely efficient in structure and effectiveness.

Für Schiebeverschlüsse mit Dreh- oder Schwenkverstellung empfiehlt es sich gemäss einem weiteren Vorschlag der Erfindung, die Kippachsen der Kipphebel und/oder die Achsen ihrer Auflager radial zur Dreh- oder Schwenkachse des die Schieberplatte aufweisenden Gleit- rahmens anzuordnen. Damit sind zweckmässige und betriebssichere Anordnungen und Ausbildungen der Kipphebel an bogenförmigen Führungsbahnen gegeben.For sliding locks with rotary or pivotal adjustment it is recommended according to a further proposal of the invention, the tilting axes of the rocker arms and / or the axes of their bearing radially guiding frame to arrange for the rotational or pivot axis of the slide plate having G. This provides practical and reliable arrangements and designs of the rocker arms on curved guideways.

Im Ausführungsbeispiel nach Fig.l bis 3 bedeutet 1 den Stahlmantel eines im Bodenbereich dargestellten metallurgischen Gefässes der innenseitig, in der nicht gezeigten feuerfesten Auskleidung, einen Lochstein 2 aufweist, in den eine zweiteilige Ausgusshülse 3 eingesetzt ist, deren Durchflussöffnung 4 aen Einlauf in den linear verstellbaren Schiebeverschluss 5 bildet. Dessen lösbar am Stahlmantel 1 befestigtes Gehäuse 6 trägt unterhalb der Ausgusshülse 3 die ortsfeste Bodenplatte 7, die mit einer mit der Durchflussöffnung 4 der Hülse 3 fluchtender Durchflussöffnung 8 versehen ist. An der Bodenplatte 7 liegt die ebenfalls eine Durchflussöffnung. 9 aufweisende feuerfeste Schieberplatte 10 und daran die feuerfeste Auslaufhülse 11 an. Beide lagern in einem Gleitrahmen 12, der seinerseits in einem durch Gelenke 13 und Gelenkhebel 14 am Gehäuse 6 gehaltenen Gehäusedeckel 15 angeordnet ist. Der Gleitrahmen 12 ist dabei mittels eines andeutungsweise dargestellten Kraftgebers 16 zum Öffnen und Schliessen des Schiebeverschlusses 5 linear verstellbar unter gleichzeitiger abdichtender Anpressung der Schieberplatte 10 an die Bodenplatte 7 mit Hilfe von durch Federorgane 17 belasteten, zwischen Gehäusedeckel 15 und Gleitrahmen 12 wirkenden zweiarmigen Kipphebeln 18.In the exemplary embodiment according to FIGS. 1 to 3, 1 means the steel jacket of a metallurgical vessel shown in the base area, which has a perforated brick 2 on the inside, in the refractory lining, not shown, into which a two-part pouring sleeve 3 is inserted, the flow opening 4 of which is an inlet into the linear adjustable slide closure 5 forms. The housing 6, which is detachably fastened to the steel jacket 1, bears below the pouring sleeve 3 the stationary base plate 7, which is provided with a flow opening 8 aligned with the flow opening 4 of the sleeve 3. There is also a flow opening on the base plate 7. 9 having refractory slide plate 10 and the refractory outlet sleeve 11. Both are mounted in a sliding frame 12, which in turn is arranged in a housing cover 15 held on the housing 6 by joints 13 and articulated levers 14. The sliding frame 12 can be adjusted linearly by means of a force transducer 16, which is indicated, for opening and closing the slide closure 5, while at the same time sealingly pressing the slide plate 10 onto the base plate 7 with the aid of two-armed rocker arms 18 loaded by spring elements 17 and acting between the housing cover 15 and the sliding frame 12.

Dementsprechend ist der Gleitrahmen 12 an jeder Längsseite mit einer Führungsbahn 19 ausgestattet, die sowohl zur seitlichen Führung am Gehäusedeckel 15 als auch zur Auflage auf als Rollen 20 mit Achsen 21 ausgebildeten Auflager der an jeder Führungsbahn 19 paarweise vorgesehenen Kipphebel 18 dienen. Diese Kipphebel 18 sind in Längsrichtung der Führungsbahnen 19 des Gleitrahmens 12 bzw. mit dazu quer liegenden Kippachsen 22 im Gehäusedeckel 15 ausgerichtet. Ferner wirken sie zusammen mit den Federorganen 17, die ausserhalb des von dem Gleitrahmen 12 bestrichenen Hubweges im Gehäusedeckel 15 positioniert sind. Mithin gruppieren sich die Kipphebel-Rollen 20, welche bei geschlossenem Gehäusedeckel 15 die Kraft der Federorgane 17 auf den Gleitrahmen 12 übertragen, symmetrisch um die Ausgussachse 23 bzw. um die koaxialen Durchfluss- öffnungen 4 und 8 von Ausgusshülse 3 und Bodenplatte 7, also speziell an dem für die Abdichtung der Bodenplatte 7 und der Schieberplatte 10 massgeblichen Plattenbereich. Dort wirken der ferrostatische Druck und der fliessende Giesstrahl unmittelbar.Accordingly, the sliding frame 12 is equipped on each longitudinal side with a guide track 19, which are used both for lateral guidance on the housing cover 15 and for bearing on rollers 20 with axles 21 designed as supports of the rocker arms 18 provided in pairs on each guide track 19. These rocker arms 18 are aligned in the longitudinal direction of the guide tracks 19 of the slide frame 12 or with tilt axes 22 lying transversely thereto in the housing cover 15. Furthermore, they act together with the spring elements 17, which are positioned outside the stroke path covered by the sliding frame 12 in the housing cover 15. The rocker arm rollers 20, which transmit the force of the spring elements 17 to the slide frame 12 when the housing cover 15 is closed, are therefore grouped symmetrically around the pouring spout 23 or around the coaxial flow openings 4 and 8 of the pouring sleeve 3 and base plate 7, that is to say specifically latte area on the relevant for the sealing of the bottom plate 7 and the slide plate 10 P. The ferrostatic pressure and the flowing pouring jet have a direct effect there.

Alternativ zu den Rollen 20 lassen sich, wie aus Fig.4 ersichtlich, an den Kipphebeln 18, deren Spannungsverhältnis zu den Federorganen 17 an Schrauben 24 einstellbar ist, beispielsweise auch Gleitschuhe 25 verwenden, die weitgehend schmutzunempfindlich sind. Des weiteren ist es möglich, die Kipphebel einarmig auszubilden, d.h. deren Kippachsen 22 an dem auflagefreien Ende der Kipphebel 18 vorzusehen und die Federorgane 17 zwischen den als Auflager verwendeten Rollen 20 oder Gleitschuhen 25 einzusetzen. Obendrein können die gesonderten Führungsbahnen 19 Bestandteile des Gleitrahmens 12 sein.As an alternative to the rollers 20, as can be seen from FIG. 4, slide rockers 25, which are largely insensitive to dirt, can also be used on the rocker arms 18, the tension ratio of which can be adjusted with screws 24 to the spring members 17. Furthermore, it is possible to design the rocker arms with one arm, i.e. to provide their tilting axes 22 at the end of the rocker arm 18 which is free of support and to insert the spring members 17 between the rollers 20 or sliding blocks 25 used as supports. In addition, the separate guideways 19 can be components of the slide frame 12.

Bei der aus Fig. 5 ersichtlichen Kipphebelanordnung für Drehschiebeverschlüsse sind die Kipphebel 30 der kreisförmigen Führungsbahn 31 eines strichpunktiert angedeuteten, die nicht gezeigte feuerfeste Schieberplatte tragenden, als Drehkorb ausgebildeten Gleitrahmens angepasst. Dieser wird von den mit ihren zur Führungsbahn 31 quer gerichteten Kippachsen 33 im Gehäusedeckel 34 gelagerten und von den Federorganen 35 beaufschlagten Kipphebeln 30 über deren Gleitrollen 36 elastisch abgestützt, um die erforderliche dichte Anpressung der Schieberplatte an die Bodeplatte zu erreichen. Aus funktionellen Gründen verlaufen entsprechend den Kippachsen 33 auch die Achsen 37 der Rollen 36 radial, was bei der Anwendung von unbeweglichen Gleitschuhen an den Kipphebeln 30 nicht erforderlich ist, die dann auch eine gestreckte, der bogenförmigen Führungsbahn 31 nicht angeglichene Form haben können.In the rocker arm arrangement shown in FIG. 5 for rotary slide closures, the rocker arms 30 of the circular guideway 31 are adapted to a sliding frame which is indicated by dash-dotted lines and carries the refractory slide plate (not shown) and is designed as a rotating basket. This is supported in the housing cover 34 by the tilting axes 33 which are oriented transversely to the guide track 31 and elastically supported by the spring members 35 rocker arms 30 via their sliding rollers 36 in order to achieve the required tight pressure of the slide plate on the floor plate. For functional reasons, the axes 37 of the rollers 36 also run radially in accordance with the tilt axes 33, which is not necessary when using immovable sliding shoes on the rocker arms 30, which can then also have an elongated shape which is not matched to the arcuate guideway 31.
