Description

Schiebeverschluss für einen Metallschmelze enthaltenden Behälter Sliding closure for a container containing molten metal
Die Erfindung betrifft einen Schiebeverschluss nach dem Oberbegriff des Anspruches 1; sowie eine dazugehörige Schiebereinheit.The invention relates to a sliding closure according to the preamble of claim 1; and an associated slide unit.
Bei einem bekannten Schiebeverschluss nach der Druckschrift EP-A-0 277 146 ist eine längsverschiebbare, eine feuerfeste Verschlussplatte aufnehmende Schiebereinheit vorgesehen, welche als Schieberwagen ausgebildet ist und für ihre Längsführung daher beidseitig Rollen aufweist. Im montierten Zustand ist der Schieberwagen mit seinen Rollen auf Führungsbahnen eines Rahmens längsgeführt, der seinerseits mittels mehrerer Federorganen höhenverstellbar an einem Gehäuseoberteil gehalten ist. Der Gehäuseoberteil sei- nerseits ist am Ausguss des Metallschmelze enthaltenden Gefässes lösbar befestigt.In a known sliding closure according to the document EP-A-0 277 146, a longitudinally displaceable, fireproof closure plate receiving slide unit is provided, which is designed as a slide carriage and therefore has rollers on both sides for its longitudinal guidance. In the assembled state, the slide carriage is guided longitudinally with its rollers on guideways of a frame, which in turn is held on an upper part of the housing by means of a plurality of spring elements. The upper part of the housing on the other hand, is releasably attached to the spout of the vessel containing the molten metal.
Die Schiebereinheit kann insbesondere für einen Plattenwechsel vom Rahmen und vom Gehäuseoberteil gelöst werden, indem sie in eine ausserhalb einer Offen- und Schliessstellung liegende Position verschiebbar ist, bei der die Führungsbahnen um einen um eine die Federorgane entspannende Höhe abgesenkt sind. Der mit den Führungsbahnen versehene Rahmen ist durch seine gehäuseähnliche Ausgestaltung massiv und er ist somit relativ aufwendig und demzufolge teuer in der Herstellung gebaut.The slide unit can be detached from the frame and from the upper housing part in particular for a plate change, in that it can be moved into a position lying outside an open and closed position, in which the guideways are lowered by a height that relaxes the spring elements. The frame provided with the guideways is solid due to its housing-like design and it is therefore relatively complex and therefore expensive to manufacture.
Der vorliegenden Erfindung wurde demgegenüber die Aufgabe zugrundegelegt, einen Schiebeverschluss nach der eingangs erwähnten Gattung zu schaffen, welcher aus einer einfachen Konstruktion besteht und daher in der Fertigung kostengünstiger herstellbar ist.In contrast, the present invention was based on the object of creating a sliding closure according to the type mentioned at the outset, which consists of a simple construction and is therefore less expensive to manufacture.
Die Aufgabe ist erfindungsgemäss durch die Merkmale des Kennzeichens des Anspruches 1 gelöst.The object is achieved according to the invention by the features of the characterizing part of claim 1.
Dieser erfindungsgemässe Schiebeverschluss kann gegenüber dem oben erläuterten bekannten Verschluss bei gleichem Hub und gleichen Plattengrös- sen insbesondere in seiner Länge und Breite mit kleineren Dimensionen versehen werden. Darüberhinaus lässt sich dieser aufgrund der Tatsache, dass auf den Gehäuserahmen verzichtet werden kann, kostengünstiger herstellen.Compared to the known closure described above, this sliding closure according to the invention can be provided with smaller dimensions, in particular in terms of its length and width, with the same stroke and the same plate sizes. In addition, this can be manufactured more cost-effectively due to the fact that the housing frame can be dispensed with.
Die Vorteile des bekannten Schiebeverschlusses, wie zum Beispiel das selbsttätige Lösen und Verspannen der Schiebereinheit vom bzw. an den Gehäuseteil, sind aber mit diesem erfindungsgemässen Schiebeverschluss dennoch vollauf genutzt. Ein weiterer erheblicher Vorteil bei diesem erfindungsgemässen Schiebeverschluss besteht darin, dass die Schiebereinheit nach dem Lösen vom Gehäuseteil mit einem einfach ausgebildeten Scharnier um eine parallel zur Verschieberichtung verlaufenden Drehachse schwenkbar gelagert ist, welche auf der einen oder anderen Aussenseite des Gehäuseteils vorgesehen ist. Damit kann die Schiebereinheit bei den vielfach vorliegenden Anbauverhältnissen der Pfannen in horizontaler und nicht vertikaler Richtung geschwenkt werden.However, the advantages of the known slide lock, such as the automatic release and tensioning of the slide unit from or to the housing part, are fully utilized with this slide lock according to the invention. Another significant advantage of this slide closure according to the invention is that the slide unit, after being detached from the housing part, is pivotably mounted with a simple hinge about an axis of rotation running parallel to the direction of displacement, which is provided on one or the other outside of the housing part. This allows the slide unit to be pivoted in the horizontal and non-vertical direction given the mounting conditions of the pans.

Fig.l zeigt einen Schiebeverschluss 20 am Ausguss eines Metallschmelze enthaltenden Behälters. Von diesem Behälter, welcher mit Feuerfestmaterial ausgekleidet ist, sind nur gerade der äussere Stahlmantel 13 und ein feuerfester Lochstein 17 angedeutet. Bei diesem Behälter handelt es sich insbesondere um eine in einer Stranggiessanlage verwendete Pfanne, in die Stahlschmelze gefüllt wird. Eine feuerfeste Hülse 11 bildet die Ausgussöffnung 12 des Behälters, an die eine obere feuerfeste Verschlussplatte 22 dicht an- schliesst, welche in einem Gehäuseteil 14 des Schiebeverschlusses 20 befe- stigt ist. Eine in einer längsbeweglichen Schiebereinheit 30 gehaltene feuerfeste Verschlussplatte 23 ist mittels Federorganen 26 an die obere Platte 22 angepresst. An letztere schliesst ferner eine auswechselbare feuerfeste Ausgusshülse 16 an. Diese Platte 23 dient zum Öffnen bzw. Schliessen des Verschlusses 20, zu diesem Zwecke sie zusammen mit der sie haltenden Schiebereinheit 30 von einem Antriebsorgan verschiebbar angeordnet.Fig.l shows a slide closure 20 on the spout of a container containing molten metal. Of this container, which is lined with refractory material, only the outer steel jacket 13 and a refractory perforated brick 17 are indicated. This container is, in particular, a pan used in a continuous caster into which molten steel is poured. A fireproof sleeve 11 forms the pouring opening 12 of the container, to which an upper refractory closure plate 22 tightly connects, which is fixed in a housing part 14 of the slide closure 20. is increasing. A refractory closure plate 23 held in a longitudinally movable slide unit 30 is pressed against the upper plate 22 by means of spring members 26. An exchangeable refractory pouring sleeve 16 also connects to the latter. This plate 23 is used to open or close the closure 20, for this purpose it is displaceably arranged together with the slide unit 30 holding it by a drive element.
Erfindungsgemäss ist die Schiebereinheit 30 von mehreren senkrecht zu ihrer Längserstreckung verlaufenden Haltemitteln 40 längsverschiebbar am Gehäuseteil 14 gehalten, wobei diese Haltemittel 40 jeweils am Gehäuseteil 14 befestigt sind und gegenüberliegend ein Führungsmittel aufweisen, welches jeweils auf einer an der Schiebereinheit 30 ausgebildeten Führungsbahn 36 gleitet.According to the invention, the slide unit 30 is held in a longitudinally displaceable manner on the housing part 14 by a plurality of holding means 40 running perpendicular to its longitudinal extent, these holding means 40 each being fastened to the housing part 14 and having a guide means opposite each other, each of which slides on a guideway 36 formed on the slide unit 30.
Zweckmässigerweise sind beidseitig zu den Verschlussplatten 22, 23 je zwei Haltemittel 40 vorgesehen, welche symmetrisch zur Ausgussöffnung 12 des Behälters angeordnet sind und jeweils ein senkrecht zur Längserstreckung des Gehäuseteils 14 bzw. der Schiebereinheit 30 verlaufendes bolzenförmi- ges Verbindungsglied 25 aufweisen. Diese Verbindungsglieder 25 sind jeweils in ihrer Achsrichtung verstellbar im Gehäuseteil 14 gehalten und an ihren jeweiligen oberen Kopfscheiben 25 ' von einem als Druckfeder ausgebildeten Federorgan 26 beaufschlagt, wobei letzteres in einer Büchse 28 eingekapselt ist. Am unteren Ende der Verbindungsglieder 25 sind paarweise je zwei als Führungsmittel vorgesehene Gleitrollen 27 drehgelagert, auf welchen die Schiebereinheit 30 längsgeführt ist. Letztere hat zu diesem Zwecke beidseitig zu der in ihr einsetzbaren Verschlussplatte 23 je eine in ihrer Verschieberichtung verlaufende T-nutenförmige Ausnehmung 33, in der je zwei Führungsbahnen 36 ausgebildet sind. Diese symmetrische Anordnung der Gleitrollenpaare zur Wirkungslinie der durch das Federorgan 26 erzeugten Federkraft ermöglicht eine optimale Kraftübertragung von den Haltemitteln 40 auf die Schiebereinheit 30 und nachfolgend auf die gegeneinander anzupressenden Platten 22, 23.Two holding means 40 are expediently provided on both sides of the closure plates 22, 23, which are arranged symmetrically to the pouring opening 12 of the container and each have a bolt-shaped connecting member 25 running perpendicular to the longitudinal extent of the housing part 14 or the slide unit 30. These connecting members 25 are each adjustable in their axial direction in the housing part 14 and acted on their respective upper head disks 25 'by a spring element 26 designed as a compression spring, the latter being encapsulated in a sleeve 28. At the lower end of the connecting links 25, two sliding rollers 27, which are provided as guide means, are rotatably mounted in pairs, on which the slide unit 30 is guided longitudinally. For this purpose, the latter has, on both sides of the closure plate 23 that can be inserted in it, a T-groove-shaped recess 33 running in its direction of displacement, in each of which two guideways 36 are formed. This symmetrical arrangement of the pairs of rollers to the line of action of those generated by the spring member 26 Spring force enables optimum force transmission from the holding means 40 to the slide unit 30 and subsequently to the plates 22, 23 to be pressed against one another.
Gemass Fig. 2 sind die seitlich in der Schiebereinheit 30 als Unsichtbare veranschaulichten T-nutenförmigen Ausnehmungen 33 je in der Mitte und endseitig mit einer erweiternden Öffnung 33' versehen, welche derart bemessen und zueinander ausgebildet sind, dass die Verbindungsglieder 25 zusammen mit den Gleitrollen 27 in diese einschiebbar sind bzw. aus diesen herausgenommen werden können.According to FIG. 2, the T-groove-shaped recesses 33, which are laterally illustrated as invisible in the slide unit 30, are provided in the middle and at the end with an expanding opening 33 ′, which are dimensioned and designed with respect to one another in such a way that the connecting members 25 together with the sliding rollers 27 can be inserted or removed from them.
Fig.3 zeigt die Führungsbahnen 36, die endseitig bei den Öffnungen 33' je eine Rampe 36' mit einer solchen Höhe aufweisen, dass sich die Federorgane 26 beim Auffahren auf den Betriebsdruck verspannen bzw. beim Lösen komplett entspannen. Für das Lösen wird die Schiebereinheit 30 in eine ausserhalb der Offen- und der Schliessstellung des Verschlusses 20 liegende Position verschoben, bei der sich die Schiebereinheit vom Federdruck löst, bis sie sich mit ihren Öffnungen 33' oberhalb der Gleitrollen 27 befindet und sie dann freigegeben ist. Hierbei gelangen seitlich an der Schiebereinheit 30 angeordnete Scharnierteile 37 mit ihren Bohrungen in entsprechende Scharnierbolzen 38 am Gehäuseteil 14, wodurch die Schiebereinheit 30 ausgeschwenkt werden kann. Sie ist hierbei mittels Klauen 41 oder dergleichen an einer Schubstange 42 eines als Hydraulik-Zylinder ausgebildeten An- triebsorganes 19 angekuppelt. Diese Klauenkupplung ermöglicht als weiterer Vorteil ein selbsttätiges Lösen der Schiebereinheit 30 von der Schubstange 42.3 shows the guideways 36, each of which has a ramp 36 'at the ends at the openings 33' with a height such that the spring members 26 tension when the operating pressure is raised or completely relax when they are released. For the release, the slide unit 30 is shifted into a position lying outside the open and the closed position of the closure 20, in which the slide unit releases from the spring pressure until its openings 33 ′ are above the slide rollers 27 and then it is released . Here, hinge parts 37 arranged laterally on the slide unit 30 pass through their bores in corresponding hinge bolts 38 on the housing part 14, as a result of which the slide unit 30 can be pivoted out. It is coupled here by means of claws 41 or the like to a push rod 42 of a drive element 19 designed as a hydraulic cylinder. As a further advantage, this claw coupling enables the slide unit 30 to be released automatically from the push rod 42.
Das Scharnier 37, 38 könnte auch auf der anderen Seite der Schiebereinheit 30 oder an der kürzeren, dem Antrieb abgewandten Seite angeordnet sein. Demnach kann die Schiebereinheit je nach Plazierung des Verschlusses am Pfannenausguss auf eine der drei Seiten ausgeschwenkt werden. Da bei vielen Anwendungsfällen die Verschieberichtung der Schiebereinheit am Montageplatz in vertikaler Richtung verläuft, kann die Schiebereinheit in der dargestellten Anordnung horizontal geschwenkt werden, was mit wenig Kraftaufwand verbunden ist.The hinge 37, 38 could also be arranged on the other side of the slide unit 30 or on the shorter side facing away from the drive. Accordingly, the slide unit can be swiveled out on one of the three sides depending on the placement of the closure on the pan spout. Since in many applications the direction of displacement of the slide unit at the assembly site runs in the vertical direction, the slide unit can be pivoted horizontally in the arrangement shown, which is associated with little effort.
Die beiden jeweils auf einer Seite der Verschlussplatten 22, 23 befindlichen Haltemittel 40 sind zur Stabilisierung gegen die auftretenden Biegekräfte durch wenigstens eine Verbindungsstange 31, 32 versteift und sie bilden dadurch eine Wagenform. Die vorliegend vorgesehenen beiden Verbindungsstangen 31, 32 befinden sich zentrisch in der Ausnehmung 33. Sie weisen eine Breite auf, die annähernd derjenigen der Verbindungsglieder 25 entsprechen, so dass dieselben in bzw. aus der Ausnehmung 33 ein- bzw. herausgeführt werden können. Die Verbindungsglieder 25 sind ferner zweigeteilt und durch eine Feder Nut- Verbindung 25" oder dergleichen zusammengefügt. Auf diese Verbindungsstangen 31, 32 könnte im Prinzip auch verzichtet werden. Anstelle der Gleitrollen 27 könnten Gleitsteine benutzt werden.The two holding means 40, each located on one side of the closure plates 22, 23, are stiffened by at least one connecting rod 31, 32 for stabilization against the bending forces that occur, and thereby form a car shape. The two connecting rods 31, 32 provided in the present case are located centrally in the recess 33. They have a width which approximately corresponds to that of the connecting members 25, so that the same can be introduced into and out of the recess 33. The connecting links 25 are further divided into two and joined together by a tongue and groove connection 25 "or the like. In principle, these connecting rods 31, 32 could also be dispensed with. Instead of the sliding rollers 27, sliding blocks could be used.
Als weiterer Vorteil können diese Haltemittel 40 im Rahmen der Erfindung bei ausgeschwenkter Schiebereinheit 30 seitlich vom Gehäusteil 14 paketweise weggenommen werden. Im Gehäuseteil 14 sind zu diesem Zwecke entsprechende Aussparungen 15 vorhanden, in welche die Haltemittel passend eingeschoben werden können. Hieraus lassen sich die Federorgane 26 für die öfters notwendigen Überprüfungen ihrer Spannkraft schnell wegnehmen und wieder einsetzen. Gemäss Fig.4 sind der Schiebereinheit 30 in ihrer Mittelpartie Quer- und Längsrippen 30' zugeordnet, welche zur Verstärkung derselben gegen Ver- biegung und Torsionskräfte dienen. Der Schiebeverschluss 20 ist im übrigen in der geschlossenen Position veranschaulicht.As a further advantage, these holding means 40 can be removed laterally from the housing part 14 in packs when the slide unit 30 is pivoted out. For this purpose, corresponding recesses 15 are provided in the housing part 14, into which the holding means can be inserted in a suitable manner. From this, the spring members 26 can be quickly removed and reinserted for the often necessary checks of their clamping force. According to FIG. 4, transverse and longitudinal ribs 30 'are assigned to the slide unit 30 in their central part, which serve to reinforce them against bending and torsional forces. The sliding closure 20 is otherwise illustrated in the closed position.
Fig.5 zeigt eine Variante eines Schiebeverschlusses 50, welcher an sich ähnlich wie derjenige nach Fig.l aufgebaut ist. Es sind daher nachfolgend nur gerade die Unterschiede näher erläutert. Dieser Schiebeverschluss 50 hat wiederum einen am Behälter befestigten Gehäuseteil 54, in welchem eine stationäre feuerfeste Verschlussplatte 22 enthalten ist. Die Haltemittel 65 sind als wesentlicher Unterschied gegenüber dem Verschluss 20 nicht im Gehäuseteil 54, sondern an der Schiebereinheit 60 befestigt. Die axial bewegbaren Verbindungsglieder 55 sind zusammen mit den aus mehreren Tellerfedern gebildeten Federorganen 66 in einer Aussparung 61 der Schiebereinheit 60 gehalten. Als Führungsmittel sind den vorteilhaft wiederum vier Verbindungsgliedern 55 jeweils eine an einer horizontalen Achse 69 drehbare Gleitrolle 68 zugeordnet, welche auf einer analog zu derjenigen nach Fig.3 ausgebildeten Führungsbahn 71 am Gehäuseteil 54 gleitet. Die beiden seitlich am Gehäuseteil vorgesehenen Führungsbahnen 71 erstrecken sich in Verschieberichtung der Schiebereinheit und sie sind mit nicht näher gezeigten Rampen versehen, welche zum Be- bzw. Entlasten der Federorgane 66 dienen.FIG. 5 shows a variant of a sliding closure 50, which is constructed in a manner similar to that according to FIG. 1. Therefore, only the differences are explained in more detail below. This sliding closure 50 in turn has a housing part 54 fastened to the container, in which a stationary refractory closure plate 22 is contained. As a significant difference compared to the closure 20, the holding means 65 are not fastened in the housing part 54, but rather on the slide unit 60. The axially movable connecting members 55 are held in a recess 61 of the slide unit 60 together with the spring members 66 formed from a plurality of plate springs. As a guiding means, the four connecting members 55 are in turn each assigned a rotatable roller 68 on a horizontal axis 69, which slides on a guide track 71 designed analogously to that according to FIG. 3 on the housing part 54. The two guide tracks 71 provided on the side of the housing part extend in the direction of displacement of the slide unit and they are provided with ramps (not shown in more detail) which serve to load and unload the spring members 66.
Bei den oben erläuterten erfindungsgemässen Schiebeverschlüssen 20, 50 weisen jeweils sowohl der Gehäuseteil 14, 54 als auch die Schiebereinheit 30, 60 je eine plattenähnliche Ausbildung auf und sie sind im Betriebszustand parallel und in geringem Abstand zueinander angeordnet. Diese Schiebeverschlüsse 20, 50 können somit aufgrund dieser erfindungsgemässen Ausbildung in ihren Dimensionen kleinstmöglich gehalten werden, sei es mit Bezug auf die Bauhöhe wie auch auf dessen Länge und Breite. Hieraus ergibt sich auch eine kostengünstigere Herstellung desselben. Dieser Verschluss kann sowohl in kleineren Dimensionen für kleinere Pfannen mit bis zu 100 Tonnen Fassungvermögen als auch in grösseren Dimensionen für 300 Tonnen-Pfannen hergestellt werden.In the slide closures 20, 50 according to the invention explained above, both the housing part 14, 54 and the slide unit 30, 60 each have a plate-like design and are arranged parallel and at a short distance from one another in the operating state. The dimensions of these sliding closures 20, 50 can thus be kept as small as possible due to the inventive design, be it with Regarding the overall height as well as its length and width. This also results in a cheaper production of the same. This closure can be produced both in smaller dimensions for smaller pans with a capacity of up to 100 tons and in larger dimensions for 300 ton pans.
Im Prinzip könnte das erforderliche Federpaket für das Verspannen der feuerfesten Platten gegeneinander in an sich bekannter Weise zwischen der Schieberplatte und der Schiebereinheit vorgesehen sein. Die Haltemittel könnten dementsprechend nicht verschiebbar im Gehäuseteil oder in der Schiebereinheit angeordnet sein. In principle, the spring assembly required for bracing the refractory plates against one another could be provided between the slide plate and the slide unit in a manner known per se. Accordingly, the holding means could not be arranged displaceably in the housing part or in the slide unit.
