Abstract

A sliding closure unit for controlling the discharge of molten metal from a metallurgical vessel includes a stationary refractory plate, a stationary housing assembly for mounting the stationary refractory plate on the metallurgical vessel, a movable refractory plate, the stationary and movable refractory plates having complementary, abutting relative sliding surfaces, and a movable frame mounting the movable refractory plate for movement with respect to the stationary refractory plate. The movable frame and movable refractory plate are urged toward the stationary refractory plate by levers mounted in the housing assembly for pivotal movement about axles fixed to the housing assembly and extending transverse to the direction of movement of the movable frame and movable refractory plate. Springs are mounted in the housing assembly to urge the levers to pivot about the respective axles toward the movable frame to thereby urge the movable frame and movable refractory plate toward the stationary refractory plate. Each lever and the respective spring are arranged in an elongated configuration extending in a direction substantially parallel to the direction of movement.

Description

Die Erfindung betrifft einen Schieberverschluß für den Ausguß metallurgischer Gefäße, vorzugsweise Stahlgießpfannen, mit einem Verschlußgehäuse und einem verstellbarem, eine Schieberplatte tragenden Gleitrahmen, der zwecks Anpreßung der Schieberplatte an eine ortsfeste Bodenplatte entlang seiner Führungsbahn von mit Federorganen belasteten und an einem Ende mit Auflagern besetzten Kipphebeln abgestützt ist, wobei die Kipphebel in Richtung der Führungsbahn bzw. in Verstellrichtung des Gleitrahmens mit dazu querliegenden Kippachsen gemeinsam mit den Federorganen im Verschlußgehäuse angeordnet sind.The invention relates to a slide closure for the pouring of metallurgical vessels, preferably steel ladles, with a closure housing and an adjustable slide frame which carries a slide plate and which, for the purpose of pressing the slide plate onto a stationary base plate along its guideway, is loaded with rocker arms loaded with spring elements and at one end with supports is supported, wherein the rocker arms are arranged in the direction of the guideway or in the direction of adjustment of the slide frame with transverse transverse axes together with the spring elements in the closure housing.

Ein Schiebeverschluß dieser Art ist aus den Veröffentlichungen SU-A-772715, auf welcher der oberbegriff des Anspruchs 1 basiert, SU-A-768556 und SU-A-1053961 vorbekannt. In allen drei Fällen ist der Schieberverschluß mit zwei beidseitig der Verschlußöffnung angeordneten Kipphebeln versehen, deren Auflager in Höhe der Verschlußöffnung gegen einen unverstellbaren Tragrahmen drücken, in dem der Gleitrahmen der Schieberplatte verstellbar ist. Hieraus ergibt sich eine lediglich linienförmige und somit instabile Anpreßung der Schieberplatte gegen die ortsfeste Bodenplatte. Darüberhinaus müssen die beiden Kipphebel sehr lang bemessen sein, weil sie allein die gesamte Anpreßkraft aufbringen müssen. Die Kipphebel sind außerdem seitlich am ortsfesten Tragrahmen und somit weit außerhalb der Schieberplatte angeordnet.A sliding closure of this type is previously known from the publications SU-A-772715, on which the preamble of claim 1 is based, SU-A-768556 and SU-A-1053961. In all three cases, the slide lock is provided with two rocker arms arranged on both sides of the lock opening, the supports of which press against an unadjustable support frame at the height of the lock opening, in which the slide frame of the slide plate is adjustable. This results in a merely linear and thus unstable pressing of the slide plate against the stationary base plate. In addition, the two rocker arms must be very long because they alone have to exert the entire contact pressure. The rocker arms are also arranged on the side of the stationary support frame and thus far outside the slide plate.

Der Erfindung liegt die Aufgabe zugrunde, die Nachteile des obigen Standes der Technik zu vermeiden und einen Schieberverschluß der eingangs genannten Art zu schaffen, der eine stets metalldichte Anpreßung der Schieberplatte an die Bodenplatte gewährleistet, und dies bei einfachem Aufbau und platzparenden Abmessungen.The invention has for its object to avoid the disadvantages of the above prior art and to provide a slide closure of the type mentioned, which ensures a metal-tight pressing of the slide plate to the base plate, and this with a simple structure and space-saving dimensions.

Die gestellte Aufgabe wird gemäß der Erfindung dadurch gelöst, daß der Schieberverschluß mit vier Kipphebeln versehen ist, deren Auflager eine Stützebene für den Gleitrahmen der Schieberplatte bildet.The object is achieved according to the invention in that the slide closure is provided with four rocker arms, the support of which forms a support plane for the slide frame of the slide plate.

Ein solche Konstruktion hat den Vorteil einer flächenmäßigen und somit gleichmäßigen Anpreßung der Schieberplatte gegen die ortsfeste Bodenplatte, die insbesondere am vollen Umfang der Durchgangsbohrung des Verschlusses wirksam ist.Such a construction has the advantage of a flat and thus uniform pressing of the slide plate against the stationary base plate, which is particularly effective on the full circumference of the through hole of the closure.

Dadurch ist eine metalldichte Anpreßung der beiden Verschlußplatten in allen Arbeitsstellen des Verschlusses gewährleistet. Darüberhinaus können die Kipphebel wesentlich kleinere Abmessungen aufweisen. Sie sind außerdem direkt unter dem Gleitrahmen und dicht an den Längsseiten der Schieberplatte untergebracht. Beides ist im Sinne einer kompakten Bauweise sehr günstig.This ensures a metal-tight pressing of the two closure plates in all working positions of the closure. In addition, the rocker arms can have significantly smaller dimensions. They are also located directly under the slide frame and close to the long sides of the slide plate. Both are very cheap in terms of a compact design.

Alle diese Vorteile gelten insbesondere bei Schieberverschlüssen, deren Gleitrahmen linear verstellbar ist, wenn gemäß der Erfindung die Führungsbahn durch zwei beidseitig der Plattenöffnung am Gleitrahmen angebrachte Führungsleisten gebildet ist, wobei jeder der Führungsleisten zwei Kipphebel einschließlich der Federorgane zugeordnet sind, deren Hebelenden mit den Auflagern gegeneinander symmetrisch zur Plattenöffnung des Verschlusses stehen. Eine solche Konstruktion ist infolge der gleichmäßigen Anpreßung unmittelbar um die Plattenöffnung herum sowohl im Hinblick auf den einfachen Aufbau als aus auf die Dichtigkeit des Verschlusses sehr günstig.All of these advantages apply in particular to slide closures whose sliding frame is linearly adjustable if, according to the invention, the guideway is formed by two guide strips attached to the sliding frame on both sides of the slide opening, each of the guide strips being assigned two rocker arms including the spring elements, the lever ends of which bear with the supports against one another stand symmetrically to the plate opening of the closure. Such a construction is very favorable due to the uniform pressure directly around the plate opening both in terms of the simple structure and the tightness of the closure.

Es ist hierbei zweckmäßig, zwecks einer leichteren Zugänglichkeit der Federorgane diese im Verschlußgehäuse außerhalb des vom Gleitrahmen bestrichenen Verstellweges anzuordnen.It is expedient here, in order to make the spring elements more easily accessible, to arrange them in the closure housing outside the adjustment path covered by the sliding frame.

Für Schieberverschlüsse, deren Gleitrahmen dreh- oder schwenkverstellbar ist, sieht die Erfindung vor, daß die Kippachsen der Kipphebel und/ oder die Achsen ihre Auflager radial zur Dreh-oder Schwenkachse angeordnet sind. Damit sind konstruktive zweckmäßige und betriebssichere Anordnungen und Ausbildungen der Kipphebel entlang einer kreis- bzw. bogenförmigen Führungsbahn gegeben.For slide closures, the sliding frame of which is rotatable or pivotable, the invention provides that the tilting axes of the rocker arms and / or the axes of their supports are arranged radially to the pivoting or pivoting axis. This provides constructive, expedient and reliable arrangements and designs of the rocker arms along a circular or arcuate guideway.

Zweckmäßigerweise sind die Kipphebel und die Federorgane in einem abnehmbaren oder abschwenkbaren Gehäusedeckel angeordnet, was den Vorteil einer leichten Zugänglichkeit zu den beiden verschlußplatten mit sich bringt.The rocker arms and the spring members are expediently arranged in a removable or swiveling housing cover, which has the advantage of easy access to the two closure plates.

Im Ausführungsbeispiel nach Fig. 1 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 den Einlauf in den linear verstellbaren Schieberverschluß 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 fluchtenden 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 Schieberverschlusses 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 bottom region, 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 extends linearly into the inlet 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. The refractory slide plate 10, which also has a flow opening 9, and the refractory outlet sleeve 11 lie against the base plate 7. Both are supported in a sliding frame 12, which in turn is mounted on the housing 6 in a joint 13 and articulated lever 14 held housing cover 15 is arranged. 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 against the base plate 7 with the aid of two-armed rocker arms 18 which are loaded by spring elements 17 and act between the housing cover 15 and the sliding frame 12.

Dementsprechend ist der Gleitrahmen 12 an jeder Längsseite mit einer Führungsleiste 19 ausgestattet, die sowohl zur seitlichen Führung am Gehäusedeckel 15 als auch zur Auflage auf als Rollen 20 mit Achsen 21 ausgebildeten Auflagern der unter jeder Führungsleiste 19 paarweise vorgesehenen Kipphebel 18 dienen. Diese Kipphebel 18 sind in Längsrichtung der durch die Führungsleisten 19 gebildeten Führungsbahn 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 Durchflußöffnungen 4 und 8 von Ausgußhülse 3 und Bodenplatte 7, also speziell an dem für die Abdichtung de Bodenplatte 7 und der Schieberplatte 10 maßgeblichen Plattenbereich. Dort wirken der ferrostatische Druck und der fließende Gießstrahl unmittelbar.Accordingly, the sliding frame 12 is equipped on each longitudinal side with a guide bar 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 under each guide bar 19. These rocker arms 18 are aligned in the longitudinal direction of the guideway of the sliding frame 12 formed by the guide strips 19 or with tilting 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 members 17 to the sliding frame 12 when the housing cover 15 is closed, are grouped symmetrically about 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 on that for sealing the bottom plate 7 and the slide plate 10 relevant plate area. 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 schmutzunempflindlich 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 Führungsleisten 19 Bestandteile des Gleitrahmens 12 sein.As an alternative to the rollers 20, as can be seen in FIG. 4, on the rocker arms 18, the tension ratio of which to the spring members 17 can be adjusted by means of screws 24, sliding shoes 25, for example, which are largely insensitive to dirt, can also be used. Furthermore, it is possible to form 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 guide strips 19 can be components of the slide frame 12.

Bei der aus Fig. 5 ersichtlichen Kipphebelanordnung für einen Drehschieberverschluß sind die Kipphebel 30 der kreisförmigen Führungsbahn 31 eines strichpunktiert angedeuteten, die nicht gezeigte feuerfeste Schieberplatte tragenden, als Drehkorb ausgebildeten Gleitrahmens angepaßt. Dieser wird den mit ihren zur Führungsbahn 31 quer gerichteten Kippachsen 33 im Gehäusedekkel 34 gelagerten und von den Federorganen 35 beauschlagten Kipphebeln 30 über deren Gleitrollen 36 elastisch abgestützt, um die erforderliche dichte Anpressung der Schieberplatte an die Bodenplatte 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 a rotary slide valve closure, the rocker arms 30 are adapted to the circular guideway 31 of a sliding frame, indicated by dash-dotted lines and carrying the refractory slide plate, not shown, designed as a rotating basket. This is elastically supported with its tilting axles 33, which are oriented transversely to the guideway 31 in the housing cover 34 and acted upon by the spring members 35, via their sliding rollers 36 in order to achieve the required tight pressure of the slide plate on the base 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.
