Description

Schiebeverschluss am Ausguss eines insbesondere Metallschmelz enthaltenden Gefasses sowie zugehörige feuerfeste VerschlusstSliding closure on the spout of a vessel, in particular containing metal melt, and associated fire-resistant closure
Die Erfindung betrifft einen Schiebeverschluss am Ausguss ein insbesondere Metallschmelze enthaltenden Gefasses, mit wenigstens zwei mit Durchflussöffnungen versehenen feuerfeste Verschlussteilen, die ins Gefässinnere ragen und darin Gleit¬ flächen aufweisen, an denen sie relativ gegeneinander abdicht verschiebbar angeordnet sind, sowie die zugehörigen feuerfest Verschlussteile.The invention relates to a sliding closure on the spout of a vessel containing, in particular, molten metal, with at least two refractory closure parts provided with throughflow openings, which protrude into the interior of the vessel and have sliding surfaces therein, on which they are arranged so as to be displaceable relative to one another, and the associated refractory closure parts.
Ein Zuflussstellglied der eingangs beschriebenen Gattung (DE-PS 35 40 202) besteht im wesentlichen aus zwei konzentris zueinander angeordneten, ins Gefäss hineinragender und darin gegeneinander bewegbaren Rohren mit Oeffnungen für den Schmel¬ zendurchtritt. Durch axiale Hubbewegung und/oder Drehbewegung lassen sich die Oeffnungen der Rohre mehr oder weniger zur Deckung bringen und damit die abfliessende Schmelze entsprechend mengenmässig regulieren. Die beiden feuerfesten Rohre sind in den sich gegenseitig berührenden Flächenbereichen zur Erzielung einer absoluten Dichtheit sehr genau zu bearbeiten. Die Bearbei¬ tung dieser Rotationsflächen ist daher relativ aufwendig. Zudem ist bei der Montage und auch im Betriebszustand dieses Zufluss¬ stellgliedes die Gefahr eines Abbrechens der Rohre aufgrund von möglichen auftretenden Querkräften relativ gross.An inflow actuator of the type described at the beginning (DE-PS 35 40 202) consists essentially of two concentrically arranged, protruding into the vessel and therein pipes movable against one another with openings for melt passage. By means of an axial stroke movement and / or a rotary movement, the openings of the tubes can more or less coincide and the quantity of the melt flowing away can be regulated accordingly. The two refractory pipes must be machined very precisely in the mutually contacting surface areas in order to achieve absolute tightness. The processing of these surfaces of rotation is therefore relatively complex. In addition, during the installation and also in the operating state of this inflow actuator, the risk of the pipes breaking off is relatively high due to possible transverse forces that may occur.
Aufgabe vorliegender Erfindung ist es, einen Schiebeverschluss der genannten Gattung derart weiterzubilden, dass dessen Ver¬ schlussteile einfacher und damit kostengünstiger herstellbar sind und mit ihnen überdies eine erhöhte Betriebssicherheit erzielt wird.The object of the present invention is to develop a slide closure of the type mentioned in such a way that its closure parts can be manufactured more easily and therefore more cost-effectively and moreover an increased operational reliability is achieved with them.
Die Aufgabe ist erfindungsgemäss dadurch gelöst, dass die Ver- schlussteile innerhalb des Gef sses mindestens je eine annähernd ebene Gleitfläche aufweisen, an denen sie zum Oeffnen resp. Schliessen der Durchflussöffnung gegeneinander abdichtend ver¬ schiebbar sind. Die ebenen Gleitflächen sind einfach herstellbar und gewährleisten eine optimale Betriebssicherheit.The object is achieved according to the invention in that the closure parts within the vessel each have at least one approximately flat sliding surface on which they can be opened or opened. Closing the flow opening are displaceable sealingly against each other. The flat sliding surfaces are easy to manufacture and ensure optimum operational reliability.
Bei einer vorteilhaften Ausbildung der Erfindung ist das eine Verschlussteil im Gefässausguss feststehend und das andere innerhalb des Gefasses verschiebbar angeordnet. Für die beiden Verschlussteile können jeweils eine oder aber zwei zueinander parallele Gleitflächen vorgesehen sein.In an advantageous embodiment of the invention, one closure part is fixed in the vessel spout and the other is arranged displaceably within the vessel. One or two mutually parallel sliding surfaces can be provided for the two closure parts.
Bei einer Variante enthält das im Gefässausguss feststehende Verschlussteil innerhalb des Gefasses eine Aussparung, in wel¬ cher eine Platte zum Oeffnen oder Schliessen der Ausgussöffnung bewegbar ist. Die Erfindung ist auch sehr gut geeignet für das Dünnbrammen- giessen, bei dem die Durchflussöffnungen schlitzförmig ausgebil det sind.In one variant, the closure part fixed in the vessel spout contains a recess in the vessel in which a plate for opening or closing the spout opening can be moved. The invention is also very well suited for thin slab casting, in which the flow openings are designed in the form of slots.
Ausführungsbeispiele sowie weitere Vorteile der Erfindung sind im folgenden anhand schematischer Zeichnungen näher erläutert.Exemplary embodiments and further advantages of the invention are explained in more detail below with the aid of schematic drawings.

In Fig.l ist ein Schiebeverschluss 10 gezeigt, der im Ausguss eines nur andeutungsweise gezeigten Metallschmelze enthaltende Gefasses 12, bspw. ein Verteiler bei Stranggiessanlagen, ange¬ ordnet ist. Der Verschluss 10 besteht im wesentlichen aus eine feststehenden feuerfesten Verschlussteil 11 und einem in diese längsgeführten beweglichen feuerfesten Verschlussteil 15. Ersteres ist mit seinem hülsenförmigen Teil 14 im feuerfesten Gefassboden eingebettet und weist eine ins Gefässinnere ragend plattenförmige Verlängerung 16 auf, die eine in Verschieberich tung des beweglichen Teiles 15 parallel verlaufende ebene Gleit¬ fläche 17 hat, die mit einer Gleitfläche 18 gebildet durch eine Segmentausschnitt im beweglichen Verschlussteil 15 in dichtender Berührung steht. Eine in der plattenförmigen Verlängerung 16 an¬ geordneten Durchflussöffnung 19 lässt sich durch Verschieben des Verschlussteiles 15 mehr oder weniger in Ueberdeckung mit einer Durchflussöffnung 19' des Teiles 15 bringen, welches von einem nicht dargestellten Antrieb höhenverstellbar geführt ist und ei AbfHessen der Metallschmelze aus dieser Oeffnung 19' beispiels¬ weise in eine Stranggiesskokille ermöglicht. Die ebenen Gleit¬ flächen 17, 18 der Verschlussteile 11, 15 sind nochmals aus der Fig.2 ersichtlich.FIG. 1 shows a slide closure 10 which is arranged in the pouring of a vessel 12, which is only hinted at, for example, a distributor in continuous casting plants. The closure 10 consists essentially of a fixed refractory closure part 11 and a longitudinally guided, movable refractory closure part 15. The former is embedded with its sleeve-shaped part 14 in the refractory bottom of the vessel and has a plate-shaped extension 16 projecting into the interior of the vessel, one of which is displaceable tion of the movable part 15 has a parallel plane sliding surface 17 which is in sealing contact with a sliding surface 18 formed by a segment cutout in the movable closure part 15. A flow opening 19 arranged in the plate-shaped extension 16 can be more or less overlapped by moving the closure part 15 with a flow opening 19 'of the part 15, which is adjustable in height by a drive (not shown) and the metal melt is removed from this opening 19 'made possible, for example, in a continuous casting mold. The flat sliding surfaces 17, 18 of the closure parts 11, 15 can be seen again from FIG.
Der Schiebeverschluss 20 gemäss Fig.3 hat ein in einem nur teil¬ weise dargestellten Pfannenboden 22 einge örteltes feuerfestes Verschlussteil 23, das rechteckförmig und mit zwei zueinander parallelen Gleitflächen 25 und 26 ausgebildet ist. Diese Gleit¬ flächen 25, 26 stehen in dichtender Berührung mit Gleitflächen 27 und 28 eines in Höhenrichtung 29 verstellbaren U-förmigen feuerfesten Verschlussteiles 24, welches in seinen Schenkeln je eine quer durchgehende Oeffnung 32 hat, die sich - wie gezeigt bei geöffnetem Verschluss 20 mit der Durchflussöffnung 33 des feststehenden Verschlussteiles 24 überdecken.The sliding closure 20 according to FIG. 3 has a fireproof closure part 23 which is located in a pan bottom 22 which is only partially shown and which is rectangular and is designed with two mutually parallel sliding surfaces 25 and 26. These sliding surfaces 25, 26 are in sealing contact with sliding surfaces 27 and 28 of a U-shaped refractory closure part 24 which can be adjusted in the height direction 29 and which each have a transverse opening 32 in its legs, which - as shown with the closure 20 open - also cover the flow opening 33 of the fixed closure part 24.
Fig.4 zeigt den Schiebeverschluss 20 an der Pfanne 22 sowie die dazugehörige Antriebseinrichtung 35, 36. Der höhenverstellbare Verschlussteil 24 ist über ein Gestänge 36 von einem seitlich a der Pfanne 22 gehaltenen, eine Kolben-Zylinder-Einheit bildende Antrieb 35 verschiebbar gehalten. Der Antrieb 35 ist über ein Scharniergelenk 37 an der Pfanne 22 gehalten und über Verstell- schr'auben 38 zwecks achsparalleler Einstellung zum Verschluss¬ teil 24 positioniert. Eine feuerfeste Verlängerungsstange 31 de Verschlussteiles 24 ist mittels eines Bolzens 43 am Gestänge 36 so gehalten, dass es senkrecht zu den Gleitflächen 27, 28 mit ausreichendem Spiel, hingegen in Richtung der Gleitflächen 27, 28 fixiert ist, wie in Fig.5 dargestellt ist. Dadurch ist dies Verschlussteil 24 einerseits vor einem Abbrechen gesichert und andererseits in bezug auf das feststehende Verschlussteil 23 positioniert. Zu dieser Positionierung weist die Stange 31 an seinem oberen Ende zwei Anschlagflächen 41 und 42 auf, die ein spielfreie Zentrierung dieser Stange 31 in einer Aussparung 39 des Gestänges 36 ermöglicht. Das Verschlussteil 24 könnte zum Regulieren des Verschlusses 20 ebensogut horizontal oder in einer Schwenkbewegung verschoben werden.4 shows the sliding closure 20 on the pan 22 and the associated drive device 35, 36. The height-adjustable closure part 24 is held in a displaceable manner via a linkage 36 by a drive 35 which is held laterally on the pan 22 and forms a piston-cylinder unit. The actuator 35 is held via a hinge 37 to the pan 22, and obliquely on VG 'AUBEN 38 for the purpose of axially parallel attitude to Verschluss¬ part 24 is positioned. A fireproof extension rod 31 de closure part 24 is held by a bolt 43 on the linkage 36 so that it is perpendicular to the sliding surfaces 27, 28 with sufficient play, however, is fixed in the direction of the sliding surfaces 27, 28, as shown in Fig.5. As a result, this closure part 24 is on the one hand secured against breaking off and on the other hand positioned in relation to the fixed closure part 23. For this positioning, the rod 31 has two stop surfaces 41 and 42 at its upper end, which enables this rod 31 to be centered in a recess 39 of the linkage 36 without play. The closure part 24 could just as well be moved horizontally or in a pivoting movement to regulate the closure 20.
Der Schiebeverschluss 50 nach Fig.6 und Fig.7 hat wiederum ein im Gef ssboden 52 feststehendes feuerfestes Verschlussteil 53, dessen Durchflussöffnung 55 sich im Gefässinnern quer und davo ausgehend vertikal durch eine zusätzliche Hülse 56 oder ein Giessrohr vertikal aus dem Gefäss erstreckt. Das feststehende Verschlussteil 53 hat eine die quere Oeffnung 55 durchbrechend Aussparung 57, in der eine feuerfeste Platte 54 abdichtend ver schiebbar geführt ist. 'Durch Längs- und/oder Schwenkbewegung dieser Platte 54 mit seiner queren Oeffnung 55' lässt sich die Metallschmelze reguliert abgiessen. Die Platte 54 hat überdies eine feuerfeste Verlängerung 58 und kann ähnlich dem Verschlus nach Fig.4 verschoben werden. Die Stange 58 könnte auch seitli oder nach unten aus der Pfanne 52 geführt sein.The slide closure 50 according to FIGS. 6 and 7 in turn has a refractory closure part 53 fixed in the bottom 52 of the vessel, the flow opening 55 of which extends transversely and vertically from the inside of the vessel through an additional sleeve 56 or a pouring tube vertically from the vessel. The fixed closure member 53 has a transverse opening 55 through recess 57 in which a refractory plate 54 is sealingly guided ver. By longitudinal and / or pivoting movement of this plate 54 with its transverse opening 55 ', the molten metal can be poured off in a regulated manner. The plate 54 also has a refractory extension 58 and can be moved similar to the closure shown in Figure 4. The rod 58 could also be led laterally or downwards from the pan 52.
Der Schiebeverschluss 60 gemäss Fig.8 unterscheidet sich von demjenigen aus Fig.3 nur insofern, als seine feuerfesten Ver¬ schlussteile 63 und 64 länglich und deren Durchflussöffnungen und 66 schlitzförmig ausgebildet sind. Insbesondere beim Dünn- brammengiessen besteht das Erfordernis, zum Vergiessen eines Bandes die Ausgussöffnung 66 aus dem Behälter 62 schlitzförmi zu versehen. Die sich in horizontaler Richtung erstreckenden Durchflussöffnungen 65 des beweglichen Verschlussteiles 64 üb decken sich in Offenstellung wiederum mit quer einlaufenden u von diesen in vertikale Richtung übergehende Durchflussöffnun 66. Durch Höhenverstellung 67 des Teiles 64 kann eine genau do¬ sierte Menge von Schmelze bandförmig aus dem Behälter abgegossen werden.The sliding closure 60 according to FIG. 8 differs from that from FIG. 3 only in that its refractory closure parts 63 and 64 are elongated and their flow openings and 66 are slit-shaped. In particular in the case of thin slab casting, there is a need to provide the pouring opening 66 from the container 62 in the form of a slot for casting a strip. The flow openings 65 of the movable closure part 64, which extend in the horizontal direction, overlap in the open position with flow openings running transversely and passing from them in the vertical direction 66. By adjusting the height 67 of the part 64, a precisely metered amount of melt can be poured out of the container in the form of a band.
Insbesondere der Schiebeverschluss 60 nach Fig.8 Hesse sich, bspw. zum Abgiessen von Leichtmetallschmelzen, mit einer an¬ nähernd horizontal aus der Pfanne führenden Oeffnung 66 des Ver¬ schlussteiles 63 einbauen. Damit kämen auch die Gleitflächen der beiden Verschlussteile 63 und 64 annähernd horizontal ins Gefäss zu liegen.In particular, the sliding closure 60 according to FIG. 8 Hesse is installed, for example for pouring light metal melts, with an opening 66 of the closure part 63 which leads approximately horizontally out of the pan. This would also result in the sliding surfaces of the two closure parts 63 and 64 lying approximately horizontally in the vessel.
Als weitere nicht dargestellte Variante der Erfindung wäre denk¬ bar, wenn beispielsweise beim Schiebeverschluss nach Fig.3 der obere Verschlussteil feststehend, während der untere längsbeweg¬ lich im Gefassboden geführt wäre. A further variant of the invention, not shown, would be conceivable if, for example in the sliding closure according to FIG.
