Abstract

A valve plate for a sliding gate valve has a refractory plate and a metal shell surrounding it. Associated with the plate is a centering device which is preferably constituted by two abutment surfaces, which are arranged at a defined spacing from one another and which rise up substantially and at least partially perpendicular towards a plate support constituted by a metal shell and have a thickness substantially equal to the metal shell thickness. These abutment surfaces are so arranged that, in an inserted and centered state of the plate, they engage correspondingly shaped abutment surfaces on a metal frame. The plate may, thus, be manufactured simply and economically.

With this type of centering, it is necessary that such an approach is available. From this, the shape of the plate can only be changed to a limited extent.

Bei einer bekannten Gleitdüsenplatte nach der Druckschrift DE-A-44 33 356 weist das die Platte unten und seitlich umgebende Metallgehäuse einen oder eine Mehrzahl von Vorsprüngen auf, welche in entsprechende Ausnehmungen des Metallrahmens passen. Im eingelegten Zustand der Platte sind deren Vorsprünge im Metallrahmen mit einem seitlichen Spiel im Bereich zwischen 0.1 und 1 Millimeter in Verschieberichtung der Platte gehalten. Diese Vorsprünge sind daher mit einer engen Toleranz zu versehen und dementsprechend sind sie jeweils aufwendig herzustellen.In a known sliding nozzle plate according to DE-A-44 33 356 the metal housing surrounding the plate below and on the side has one or a plurality of projections, which in corresponding recesses of the metal frame. When the plate is inserted, there are Projections in the metal frame with a lateral play in the area between 0.1 and 1 millimeter held in the direction of displacement of the plate. These ledges are therefore to be provided with a narrow tolerance and accordingly they are expensive to manufacture.

Der vorliegenden Erfindung wurde demgegenüber die Aufgabe zugrundegelegt, eine Verschlussplatte nach der eingangs erwähnten Gattung zu schaffen, welche bei genauer Zentrierung in einem Metallrahmen einfach und kostengünstig herstellbar ist. Ausserdem soll diese Verschlussplatte mit ihrer Dimensionierung derart ausgebildet sein, dass hierdurch der Platzbedarf bei einer Stapelung solcher Platten minimal gehalten werden kann.The present invention was based on the object to create a closure plate according to the type mentioned at the outset, which, with precise centering in a metal frame, is simple and inexpensive can be produced. In addition, this closure plate with its dimensions be designed such that the space required stacking of such plates was kept to a minimum can be.

Die Aufgabe ist erfindungsgemäss dadurch gelöst, dass das Zentriermittel durch mindestens zwei in einem definierten Abstand separat zueinander angeordneten Anschlagflächen gebildet ist, welche je quer zu der Platten-Längsachse verlaufen und annähernd eine Dicke wie die Blechmanteldicke aufweisen, wobei diese Anschlagflächen dazu dienen, dass sie für die Zentrierung der Platte an entsprechend ausgebildeten Anschlagflächen am Metallrahmen anliegen.According to the invention, the object is achieved in that the centering means by at least two arranged separately from each other at a defined distance Stop faces is formed, which ever transverse to the longitudinal axis of the plate and approximately a thickness like that Have sheet metal jacket thickness, these stop surfaces serve that they for centering the plate on appropriately trained stop surfaces rest on the metal frame.

Diese Verschlussplatte lässt sich mit ihrer erfindungsgemässen Ausbildung herstellungsmässig einfach fertigen und es ist mit ihr aber trotzdem eine solche Zentrierung in einem Metallrahmen des Schiebeverschlusses gewährleistet, dass mit diesem äusserst betriebssicher gearbeitet werden kann.

Fig. 1 zeigt ausschnittweise einen Schiebeverschluss 10 am Ausguss eines Metallschmelze enthaltenden Behälters, wobei von letzterem nur gerade der äussere Stahlmantel 13 und ein feuerfester Lochstein 17 angedeutet sind. Bei diesem Behälter handelt es sich vorzugsweise um eine mit Stahlschmelze füllbare Pfanne für eine Stranggiessanlage. Eine feuerfeste Hülse 11 bildet die Ausgussöffnung 12 aus diesem Behälter. An diese Hülse 11 schliesst eine obere, im Metallrahmen 14 des Schiebeverschlusses 10 befestigte Verschlussplatte 20 dicht an, welche mit einer darunter angeordneten verschiebbaren Verschlussplatte 20 zusammenwirkt. Die untere Verschlussplatte 20 dient zum Öffnen bzw. Schliessen des Verschlusses 10 und sie ist zu diesem Zwecke in einer als Metallrahmen 15 ausgebildeten längsbeweglichen Schiebereinheit gehalten, in der überdies eine an die Platte 20 anschliessende feuerfeste Ausgusshülse 16 montiert ist. Dieser Schiebeverschluss 10 ist in an sich herkömmlicher Weise ausgestaltet und daher nachfolgend nicht mehr im Einzelnen dargetan.Fig. 1 shows a section of a sliding closure 10 on the spout Containers containing molten metal, only the latter of the latter outer steel jacket 13 and a refractory perforated brick 17 are indicated. at this container is preferably one with molten steel fillable pan for a continuous caster. A refractory sleeve 11 forms the pouring opening 12 from this container. This sleeve 11 closes one Upper closure plate fastened in the metal frame 14 of the sliding closure 10 20 close together, which with a slidable arranged below Closing plate 20 interacts. The lower closure plate 20 serves to open and close the closure 10 and it is to this Purposes in a longitudinally movable as a metal frame 15 Slider unit is held, in which, in addition, one adjoining the plate 20 refractory pouring sleeve 16 is mounted. This slide closure 10 is designed in a conventional manner and therefore not subsequently explained in more detail.

Die Verschlussplatten 20 weisen jeweils einen vorgefertigten, üblicherweise tiefgezogenen gestanzten Blechmantel 21 und eine in diesen eingemörtelten, aus einem feuerfesten keramischen Material bestehende Platte 22 auf. Der Mörtel 28 wird im plastischen Zustand in den Blechmantel 21 eingestrichen und nach dem Einlegen der Feuerfestplatte trocknet dieser und hält letztere darin fest. Diese als Einheit separat gefertigte Platte 20 wird dann als Ganzes lose in den Metallrahmen 14, 15 eingelegt und darin ist sie über ein Zentriermittel zumindest in Verschieberichtung gehalten.The closure plates 20 each have a prefabricated, usually deep-drawn stamped sheet metal jacket 21 and a mortar, plate 22 made of a refractory ceramic material. The Mortar 28 is brushed into the sheet metal jacket 21 in the plastic state and after inserting the refractory plate, it dries and holds the latter stuck in it. This plate 20, which is manufactured separately as a unit, is then produced as a whole loosely inserted into the metal frame 14, 15 and therein it is over a Centering means held at least in the direction of displacement.

Gemäss Fig.2 und Fig.3 ist der Verschlussplatte 20 ein Zentriermittel zugeordnet, welches erfindungsgemäss durch vorzugsweise zwei in einem definierten Abstand zueinander angeordnete Anschlagflächen 23, 24 gebildet ist. Diese Anschlagflächen 23, 24 erheben sich gemäss Fig.2 annähernd senkrecht zu der vom Blechmantel 21 gebildeten Plattenauflage 26 und sie sind jeweils annähernd mit einer Höhe wie die Blechmanteldicke 21' versehen. Diese Anschlagflächen 23, 24 liegen im eingelegten und zentrierten Zustand der Platte 20 an entsprechend ausgebildeten Anschlagflächen 18', 19' am Metallrahmen 14, 15 an, so dass die Platte 20 darin lose und in Verschieberichtung annähernd spielfrei gehalten ist. Der Metallrahmen 14, 15 weist hiefür je eine vorstehende Nase 18, 19 mit je einer Anschlagfläche 18', 19' auf. Diese zusammenwirkenden Anschlagflächen 18', 19' bzw. 23, 24 sind jeweils mit Bezug auf die Platten-Auflagefläche 26 als gerade senkrechte Flächen ausgebildet; sie könnten jeweils auch etwas bombiert oder für ein leichteres Hineinlegen der Platte in den Rahmen mit einer Anschrägung versehen sein. According to FIGS. 2 and 3, the closing plate 20 is assigned a centering means, which according to the invention is preferably defined by two in one Stop surfaces 23, 24 arranged at a distance from one another is formed. These stop surfaces 23, 24 rise approximately vertically according to FIG to the plate support 26 formed by the sheet metal jacket 21 and they are each provided approximately with a height like the sheet metal jacket thickness 21 '. These stop surfaces 23, 24 are in the inserted and centered state the plate 20 on appropriately designed stop surfaces 18 ', 19' on Metal frame 14, 15 on, so that the plate 20 is loose and in the direction of displacement is kept almost free of play. The metal frame 14, 15 has for each a protruding nose 18, 19 each with a stop surface 18 ', 19' on. These cooperating stop surfaces 18 ', 19' and 23, 24 are each with respect to the plate support surface 26 as a straight vertical Surfaces formed; they could also be somewhat bombshell or for one Make it easier to place the plate in the frame with a chamfer his.

Bei einer sehr vorteilhaften Ausführung ist der Blechmantel 21 zur Bildung der jeweiligen Anschlagfläche 23, 24 mit je einer Trennstelle und bei dieser je einer nach innen abgebogenen Rippe 21" versehen. Die mit dieser Trennstelle im Blechmantel 21 erzeugte Stirnkante bildet demgemäss die entsprechende Anschlagfläche 23, 24, welche durch die Rippe 21" freigegeben ist. Die Rippe 21" ist hierbei derart nach innen abgebogen, dass sie mit ihrer unteren Kante bei der endseitigen Trennstelle ohne Zwischenraum an die obere des die Fortsetzung bildenden Blechmantels angrenzt. Dies bietet den Vorteil, dass kein Mörtel 28 zwischen der Rippe und der Blechmantel-Fortsetzung durchdringen kann und diese Anschlagfläche 24 demnach nicht verschmutzt wird.In a very advantageous embodiment, the sheet metal jacket 21 is for formation the respective stop surface 23, 24, each with a separation point and at this each provided with a rib 21 "bent inwards. The one with this separation point The end edge produced in the sheet metal jacket 21 accordingly forms the corresponding one Stop surface 23, 24, which is released by the rib 21 ". The rib 21 "here is bent inwards in such a way that it fits with her lower edge at the end separation point without space to the upper of the sheet metal jacket forming the continuation. This offers the Advantage that there is no mortar 28 between the rib and the sheet metal jacket continuation can penetrate and therefore not stop surface 24 is polluted.

Diese Rippe 21" mit der entsprechenden Trennstelle lässt sich aufgrund des durch Tiefziehen hergestellten Blechmantels 21 in einem Arbeitsgang fertigen. Die den Blechmantel aufnehmende Werkzeugform sowie der Stempel sind derart ausgebildet, dass während dem Hineindrücken des Stempels in die Werkzeugform der Blechmantel wannenförmig tiefgezogen und an der besagten Stelle getrennt wird. Die mit diesem Tiefziehverfahren erzeugte Anschlagfläche 23, 24 kann ohne spezielle Nachbearbeitung mit einer genauen Masstoleranz im Zehntelmillimeterbereich versehen werden. Eine solche Verschlussplatte lässt sich somit auf einfachste Weise mit diesem oben erläuterten Zentriermittel ausstatten.This rib 21 "with the corresponding separation point can be due to the Manufacture by deep drawing manufactured sheet metal jacket 21 in one operation. The tool shape that receives the metal jacket and the stamp are designed such that while the stamp is pushed in the tool shape of the sheet metal jacket deep-drawn and on the said point is separated. The one produced with this deep drawing process Stop surface 23, 24 can be processed with a precise without special post-processing Dimensional tolerance in the tenths of a millimeter range. Such Closing plate can thus be easily with this above Equip the centering device described.

Gemäss Fig.3 erstrecken sich diese beiden geradlinigen länglichen Anschlagflächen 23, 24 auf der Rückseite der Platte im rechten Winkel zur Platten-Längsachse 21A. Hierbei sind sie in gleichem Abstand zur Ausgussöffnung 12 angeordnet und mit einer Länge annähernd der halben Plattenbreite versehen, die derart bemessen sind, dass die im Betriebszustand auf die jeweilige Anschlagfläche 23, 24 des Blechmantels 21 entstehenden Druckkräfte ohne Deformation aufgenommen werden.According to Figure 3, these two straight elongate stop surfaces extend 23, 24 on the back of the plate at right angles to the longitudinal axis of the plate 21A. Here they are at the same distance from the pouring spout 12 arranged and provided with a length of approximately half the plate width, which are dimensioned in such a way that they correspond to the respective operating conditions Stop surface 23, 24 of the sheet metal jacket 21 resulting pressure forces can be recorded without deformation.

Durch diese Anordnung, dass die eine Anschlagfläche 23 auf der einen und die andere Anschlagfläche 24 auf der anderen Seite der Ausgussöffnung 12 angeordnet ist und hieraus zwischen diesen ein Abstand von mehr als die halbe Plattenlänge entsteht, und dass die Anschlagflächen 23, 24 der Platten nach auswärts gerichtet sind, ergibt sich bei der Montage der Platte 20 im jeweiligen Metallrahmen 14, 15 ein weiterer Vorteil im Rahmen der Erfindung. Die Platten 20 sind vor dem Einsetzen im kalten Zustand mit Raumtemperatur, indessen die Metallrahmen 14, 15 des Schiebeverschlusses 10 an der Pfanne in der Regel vom vorherigen Einsatz noch eine Temperatur von ca. 200° bis 300° Celsius aufweisen. Durch diese Temperaturdifferenz kann die Platte leichter in den jeweiligen Metallrahmen eingelegt werden, da der Abstand zwischen den Anschlagflächen 23, 24 der Platten zu denjenigen der Metallrahmen um einige Zehntelmillimeter kleiner ist, als wenn keine Temperaturdifferenz bestehen würde. Nach der Inbetriebsetzung des Schiebeverschlusses an der Pfanne und dem Auffüllen von letzterer mit flüssigem Stahl erhitzen sich die Platten 20 als auch die Metallrahmen 14, 15 zumindest bei den Anschlagflächen 23, 24 auf die gleiche Temperatur von bspw. ca. 300 - 400° C. Dadurch dehnt sich die Platte gegenüber dem Metallrahmen verhältnismässig stärker aus und sie verspannt sich in einem gewissen Grade im Metallrahmen.By this arrangement that the one stop surface 23 on one and the other stop surface 24 on the other side of the pouring opening 12 is arranged and between them a distance of more than that half plate length arises, and that the stop surfaces 23, 24 of the plates are directed outwards, results in the assembly of the plate 20 in respective metal frame 14, 15 another advantage within the scope of the invention. The plates 20 are in the cold state at room temperature before insertion, meanwhile, the metal frame 14, 15 of the slide closure 10 the pan usually still has a temperature of from previous use about 200 ° to 300 ° Celsius. This temperature difference can the plate can be inserted more easily into the respective metal frame since the Distance between the stop surfaces 23, 24 of the plates to those of the Metal frame is a few tenths of a millimeter smaller than if there was no temperature difference would exist. After putting the sliding lock into operation on the pan and filling the latter with liquid steel the plates 20 and the metal frames 14, 15 at least heat up the stop surfaces 23, 24 to the same temperature, for example approx. 300 - 400 ° C. This causes the plate to expand relatively in relation to the metal frame stronger and she tensions to a certain extent in Metal frame.

Fig.3A zeigt einen teilweisen Querschnitt der Zentrierung der Platte 20 im metallischen Rahmen 15 quer zur Platten-Längsachse 21A. Hieraus ist ersichtlich, dass die Rippe 21" in gleichmässigem Abstand zur Plattenauflage 26 ausgebildet ist und die Feuerfestplatte 22 vorzugsweise innenseitig an dieser Rippe 21" anliegt. Dies ermöglicht nebst einer parallelen Ausrichtung eine definierte Distanz zwischen der Feuerfestplatte 22 und der Auflage 26. Ausserdem sind die Nase 19 des Metallrahmens und die Rippe 21" je mit einer solchen Länge versehen, dass die Rippe 21" beidseitig mit ihren Enden 27 mit wenig Spiel zu der Aussenseite 28' der Nase 19 im eingelegten Zustand der Platte angeordnet ist, so dass die Platte 20 auch quer zur Platten-Längsachse 21A gewissermassen zentriert ist.3A shows a partial cross section of the centering of the plate 20 in metallic frame 15 transverse to the longitudinal axis 21A of the plate. From this it can be seen that the rib 21 "at a uniform distance from the plate support 26 is formed and the refractory plate 22 preferably on the inside this rib 21 "abuts. This enables, in addition to a parallel alignment a defined distance between the refractory plate 22 and the support 26. In addition, the nose 19 of the metal frame and the rib 21 "are each with provided such a length that the ends of the rib 21 "on both sides 27 with little play to the outside 28 'of the nose 19 in the inserted Condition of the plate is arranged so that the plate 20 is also transverse to the longitudinal axis of the plate 21A is somewhat centered.

Die Verschlussplatten der nachfolgend erläuterten Ausführungsbeispiele gemäss Fig.4 bis Fig. 10 sind an sich ähnlich wie die oben bereits im Detail beschriebene Platte 20 aufgebaut. Es sind daher nachfolgend nur noch die Unterschiede bzw. deren spezifische Ausbildungen erläutert. Die feuerfesten Platten 22 sind vorzugsweise jeweils in den Blechmantel eingemörtelt.The closure plates of the exemplary embodiments explained below 4 to 10 are in themselves similar to those in detail above described plate 20 built. It is therefore only the following Differences and their specific training explained. The fireproof Plates 22 are preferably each mortared in the sheet metal jacket.

Fig.4 zeigt eine Verschlussplatte 40 mit einem erfindungsgemässen Zentriermittel, bei welchem die beiden Anschlagflächen 43, 44 nebeneinander durch eine streifenförmige nach innen gebogene Rippe 41' des Blechmantels 41 gebildet sind. Diese Rippe 41' ist seitlich durch zwei Trennstellen zum Blechmantel 41 begrenzt und auf der einen Seite der Platten-Auflagefläche angeordnet. Der Metallrahmen 15 seinerseits hat eine entsprechend ausgebildete rechteckförmige Nase 36, an welcher seitlich je eine Anschlagfläche vorhanden ist, welche mit denjenigen der Platte 40 korrespondieren.4 shows a closure plate 40 with a centering means according to the invention, in which the two stop surfaces 43, 44 side by side by a strip-shaped rib 41 'of the sheet metal jacket which is bent inwards 41 are formed. This rib 41 'is laterally through two separation points Sheet metal jacket 41 limited and on one side of the plate support surface arranged. The metal frame 15 in turn has an appropriately trained rectangular nose 36, on each side of which a stop surface is present, which correspond to those of the plate 40.

Die Verschlussplatte 50 gemäss Fig. 5 unterscheidet sich zu der Platte 20, welche in Fig.2 und Fig.3 im Detail dargestellt ist, nur gerade darin, dass bei den Rippen 51" zur Bildung der Anschlagflächen 53, 54 nicht Trennstellen vorgesehen sind, sondern dass dieselben nutenförmig in den Blechmantel 51 eingedrückt sind. 5 differs from plate 20, which is shown in detail in Fig.2 and Fig.3, just in that at the ribs 51 "to form the stop surfaces 53, 54 not separating points are provided, but rather that they are groove-shaped in the sheet metal jacket 51 are indented.

Fig.6 zeigt eine Verschlussplatte 60 mit einem Blechmantel 61, bei welchem zur Bildung von Anschlagflächen 63, 64 zwei Rippen 61" analog zu denjenigen gemäss Fig.2 vorgesehen sind, jedoch mit dem Unterschied, dass beide Rippen 61" auf der längeren Seite der Auflagefläche parallel zueinander angeordnet sind.6 shows a closure plate 60 with a sheet metal jacket 61, in which to form stop surfaces 63, 64 two ribs 61 "analogous to those are provided according to Figure 2, but with the difference that both Ribs 61 "on the longer side of the support surface parallel to each other are arranged.

Fig.7 zeigt eine Verschlussplatte 70, bei welcher die erfindungsgemässen Zentriermittel wiederum als im Blechmantel 71 vorgesehene Rippen 71" - wie in Fig.3 dargestellt ist - ausgeführt sind, wobei diese Rippen 71" jedoch von der Platte 22 wegragen. Die Anschlagflächen 73, 74 sind dementsprechend durch die Stirnflächen an den Rippen 71" gebildet, indessen die Anschlagflächen des Metallrahmens von in diesem ausgebildete Längsnuten 79 bewerkstelligt sind.7 shows a closure plate 70, in which the inventive Centering means in turn as ribs 71 ″ provided in the sheet metal jacket 71. as shown in Figure 3 - are executed, but these ribs 71 " protrude from the plate 22. The stop surfaces 73, 74 are accordingly formed by the end faces on the ribs 71 ", but the stop faces of the metal frame of longitudinal grooves 79 formed therein are accomplished.

Fig.8 zeigt eine mit Anschlagflächen 83, 84 versehene Verschlussplatte 80, die sich gegenüber derjenigen nach Fig.7 einzig darin unterscheidet, als ihre Feuerfestplatte 82 mit zahnförmigen Verstärkungen 82' versehen ist, welche in die durch das Wegbiegen der Rippen gebildeten Ausnehmungen des Blechmantels 81 ragen.8 shows a closure plate 80 provided with stop surfaces 83, 84, which differs from that according to Fig. 7 only in its Refractory plate 82 is provided with tooth-shaped reinforcements 82 ', which in the recesses of the formed by the bending of the ribs Protruding sheet metal casing 81.

Bei einer Verschlussplatte 90 nach Fig.9 sind die Anschlagflächen 93, 94 von einem auf der Unterseite des Blechmantels 91 befestigten, insbesondere punktgeschweissten Blechstreifen 95 gebildet. Dieser Blechstreifen 95 ist vorzugsweise rechteckig ausgebildet und die seitlich an ihm als Anschlagflächen 93, 94 dienenden Stirnkanten sind rechtwinklig zur Längsachse der Platte 90 angeordnet.9, the stop surfaces 93, 94 from one attached to the underside of the sheet metal jacket 91, in particular spot-welded sheet metal strips 95 are formed. This sheet metal strip is 95 preferably rectangular and the side of it as stop surfaces 93, 94 serving end edges are perpendicular to the longitudinal axis of the Plate 90 arranged.

Fig. 10 und Fig. 10A zeigen eine weitere Ausführung einer Verschlussplatte 100, bei welcher die Anschlagflächen 103, 104 nach unten abgebogene Rippen 101', 103' aufweisen. Diese Anschlagflächen 103, 104 zeichnen sich durch deren kreisförmige Ausbildung aus, wobei der von diesen gebildete Kreis konzentrisch zur Ausgussöffnung der Platte angeordnet ist, hierdurch gewährleistet ist, dass diese Öffnung im Metallrahmen des Schiebeverschlusses genau zentriert ist und damit die Öffnungen der beiden Verschlussplatten zueinander konzentrisch angeordnet sind. Auf der Plattenseite mit der kleineren Auflagefläche sind zwei symmetrisch zur Platten-Längsachse angeordnete Rippen 103', derweil auf der gegenüberliegenden Seite eine Rippe 101' im Blechmantel 101 enthalten ist. Diese Anschlagflächen könnten selbstverständlich auch statt geradlinig oder kreisförmig auch mit einer anderen Form versehen sein.10 and 10A show a further embodiment of a closure plate 100, in which the stop surfaces 103, 104 ribs bent downwards 101 ', 103'. These stop surfaces 103, 104 stand out by their circular design, the one formed by them Circle is arranged concentrically to the pouring spout of the plate, thereby It is guaranteed that this opening in the metal frame of the sliding lock is exactly centered and thus the openings of the two closing plates are arranged concentrically to each other. On the record side with the smaller contact surface, two are symmetrical to the longitudinal axis of the plate arranged ribs 103 ', meanwhile on the opposite Side a rib 101 'is contained in the sheet metal jacket 101. These stop faces could of course also instead of straight or circular be given a different shape.

Vortheilhaft sind diese auf der Unterseite der Platte versehenen Anschlagflächen zwecks einfacher Herstellung direkt am Blechmantel ausgebildet. Im Prinzip könnten sie aber auch unmittelbar an der Feuerfestplatte 22 vorgesehen sein, insbesondere dann, wenn die Feuerfestplatte 22 in an sich bekannter Weise unmittelbar auf dem Metallrahmen 15 aufliegen würde und dazwischen kein Blechmantel, sondern nur ein die Platte seitlich umfassender Bandagering vorgesehen wäre. Die Anschlagflächen wären dann direkt in der Feuerfestplatte 22 enthalten, insbesondere durch eine oder zwei Ausnehmungen auf der Unterseite der Feuerfestplatte 22.These stop surfaces provided on the underside of the plate are advantageous Formed directly on the sheet metal jacket for the purpose of simple production. in the In principle, however, they could also be provided directly on the refractory plate 22 be, especially if the refractory plate 22 in a known per se Way would rest directly on the metal frame 15 and in between not a sheet metal jacket, but only one that encompasses the side of the plate Bandage ring would be provided. The stop surfaces would then be directly in contain the refractory plate 22, in particular through one or two recesses on the underside of the refractory plate 22.
