Description

Schiebeverschluss am Ausguss eines Metallschmelze enthaltenden Gefasses. Sliding closure on the spout of a vessel containing molten metal.
Die Erfindung betrifft einen Schiebeverschluss am Ausguss eines Metallschmelze enthaltenden Gefasses, mit einem Schiebergehäuse, einer darin ortsfest angeordneten Bodenplatte und einer gegen diese mittels Federorgane dichtend anpressbaren Schieberplatte, die in einer auf Führungsbahnen des Schiebergehäuses in eine Offen- bzw. eine Schliessstellung verschiebbaren und bei entspannten Federorganen ausschwenkbaren Schiebereinheit gehalten ist.The invention relates to a slide closure on the spout of a metal-containing vessel, with a slide housing, a base plate arranged therein in a stationary manner and a slide plate which can be pressed against it by means of spring elements and which can be moved in an open or a closed position on guideways of the slide housing and in a relaxed position Spring organs swiveling slide unit is held.
Bei Schiebeverschlüssen der genannten Gattung ist im allgemeine die Schiebereinheit in einem an das Schiebergehäuse befestigten Deckel verschiebbar geführt. So ist z.B. bei einem in der Druckschrift DE-OS 21 61 368 beschriebenen Schiebeverschluss ein an das Schiebergehäuse ausschwenkbar angelenkter Deckel vorgesehen, in dem die Schiebereinheit verstellbar geführt ist und der in Betriebsposition vorzugsweise von vier Schrauben an das Schiebergehäuse befestigt ist. Bei einem weiteren Schiebeverschluss gemäss der Druckschrift DE-PS 32 08 101 ist die Schiebereinheit auf Führungsleisten geführt, die an die Seitenwand des Schiebergehäuses geschraubt sind. Nach dem Lösen der die Schieber- an die Bodenplatte anpressenden Spannorgane sowie dem Wegnehmen der Führungsleisten kann die Schiebereinheit aus dem Schiebergehäuse herausgenommen werden. In einer anderen Variante ist vorgesehen, das Gehäuse mit einer wegnehmbaren Stirnwand zu versehen, nach deren Wegnahme sowie nach dem Lösen der Spannorgane die Schiebereinheit herausgefahren werden kann.In the case of slide closures of the type mentioned, the slide unit is generally guided so that it can slide in a cover attached to the slide housing. For example, in a sliding closure described in the document DE-OS 21 61 368, a hinged cover is provided which is pivoted to the slide housing and in which the slide unit is guided in an adjustable manner and which is preferably fastened to the slide housing by four screws in the operating position. In a further slide closure according to the document DE-PS 32 08 101, the slide unit is guided on guide strips which are screwed to the side wall of the slide housing. After loosening the clamping elements pressing the slide against the base plate and removing the guide strips, the slide unit can be removed from the slide housing. Another variant provides for the housing to be provided with a removable end wall, after its removal and after the tensioning members have been released, the slide unit can be moved out.
Im Betrieb werden die Schiebeverschlüsse oft bereits nach einem oder zwei Pfannenabgüssen zu Wartungszwecken und zum Auswechseln der verschlissenen feuerfesten Platten demontiert. Bei den oben erwähnten Schiebeverschlüssen müssen daher die genannten Schrauben jedesmal gelöst und die Schiebereinheit von dem Schiebergehäuse herausgenommen und entsprechend wieder montiert werden. Da diese Schiebeverschlüsse bei den Wartungsarbeiten meisten sehr stark erhitzt und verschmutzt sind, ist die von Hand durchzuführende Demontage relativ umständlich. Auch die Montage muss mit entsprechender Sorgfalt durchgeführt werden, denn die üblicherweise mit einem Drehmomentschlüssel zu befestigenden Spannschrauben erfordern eine genaue Einstellung.In operation, the sliding closures are often dismantled after just one or two ladle castings for maintenance purposes and to replace the worn refractory plates. In the case of the slide closures mentioned above, the screws mentioned must therefore be loosened each time and the slide unit must be removed from the slide housing and re-installed accordingly. Since these slide fasteners are mostly very hot and dirty during maintenance work, manual disassembly is relatively cumbersome. The assembly must also be carried out with the appropriate care, because the clamping screws, which are usually fastened with a torque wrench, require precise adjustment.
Aufgabe vorliegender Erfindung besteht demgegenüber darin, eine Schiebeverschluss der eingangs beschriebenen Gattung derart weiterzubilden, dass dessen Schiebereinheit für das sehr häufige Auswechseln der Feuerfest-Platten und -Ausgüsse auf sehr einfache und zeitsparende Weise vom Gehäuse gelöst und nach erfolgtem Feuerfestwechsel wieder in Betriebszustand gesetzt werden kann.In contrast, the object of the present invention is to develop a slide closure of the type described in the introduction in such a way that its slide unit can be detached from the housing in a very simple and time-saving manner for the very frequent replacement of the refractory plates and spouts and can be put back into operating condition after the refractory has been replaced .
Erfindungsgemäss wird diese Aufgabe dadurch gelöst, dass die Schiebereinheit in eine ausser halb der Offen- und der Schliessstellung liegenden Position verschiebbar ist, in welcher die Schiebereinheit in einer Lagerung im Schiebergehäuse schwenkbar lagert und die Führungsbahnen gegenüber den Führungsbahnen auf der übrigen Bahnlänge um eine die Federorgane entspannende Höhe abgesenkt sind.According to the invention, this object is achieved in that the Slider unit is displaceable in a position lying outside the open and the closed position, in which the slider unit is pivotably supported in a bearing in the slider housing and the guideways are lowered relative to the guideways on the remaining path length by a height that relaxes the spring elements.
Mit dieser erfindungsgemassen Gestaltung des Schiebeverschluss wird die Schiebereinheit mit der darin angeordneten Schieberplatte allein durch Verschieben derselben in der o.g. Position von der Druckbeaufschlagung der Federorgane entlastet. Man kann daher den Schiebeverschluss auf absolut einfache Art demontieren, indem die Schiebereinheit in die o.g. Position gefahren wird und dann aus dem Schiebergehäuse ausgeschwenkt wird. Bei der Montage wird die Schiebereinheit umgekehrt ins Schiebergehäuse zurückgeschwenkt und anschliessend in die Schliessstellung gefahren. Dadurch wird selbsttätig die Druckbeaufschlagung der Federorgahe genau wieder hergestellt, ohne zuätzliche Bedienungen an dem Schiebeverschluss vorzunehmen.With this design of the slide closure according to the invention, the slide unit with the slide plate arranged therein is simply moved by moving it in the above-mentioned Relieved of the pressure from the spring elements. You can therefore dismantle the slide lock in an absolutely simple way by sliding the slide unit into the above. Position is driven and then swung out of the valve body. During assembly, the slide unit is swung back into the slide housing and then moved to the closed position. As a result, the pressurization of the spring organs is automatically restored without additional operations on the slide closure.

Diese Rollen 36 sind auf Führungen 21 des Verschlussgehäuses gestützt. Die Führungen 21 ihrerseits sind an einem den Schieberwagen umgebenden Gehäuserahmen 24 befestigt, der von Federorganen 50 am Gehäuseoberteil 26 gehalten ist. Anstelle der Rollen 36 könnten beispielsweise auch Gleitschuhe verwendet werden. Erfindungsgemäss kann der Schieberwagen 30 vom Antrieb in einen ausserhalb der Schliessstellung liegenden Bereich verschoben werden, in dem die mit den Rollen 36 in Berührung stehenden Führungsbahnen 21b gegenüber der Bahn im Bereich des Betriebszustandes um eine die Federn entspannende Höhe h abgesenkt sind. Bei diesen Führungsbahnen 21b handelt es sich um Schrägflächen, die beim Verspannen ein kontinuierliches Ansteigen und beim Entspannen ein kontinuierliches Reduzieren der Federspannkraft bewirken. Nach den Schrägflächen 21b sind die Führungen 21 durch Ausnehmungen 21c mit einer Länge grösser als der Rollendurchmesser unterbrochen. Dadurch kann der Schieberwagen 30 vom Gehäuse ausgeschwenkt werden und das regelmässig erforderliche Auswechseln der verschlissenen Platten 22, 32 sowie des Wechselausgusses 34 durchgeführt werden.In the operating state, the slide carriage 30 can move from an open position into a closed position S, which is shown in FIG. 1 is indicated by dash-dotted lines, and vice versa can be shifted by means of a drive. The drive, which is not shown. it is usually a hydraulic cylinder with a push rod 28. The slide carriage 30 is held at one end by an articulated connection 29 on the push rod 28, this push rod 28 being additionally mounted in the upper housing part 26. The slide carriage 30 has on its two longitudinal sides two rotatably mounted rollers 36 with axes of rotation extending transversely to the direction of displacement. These rollers 36 are supported on guides 21 of the closure housing. The guides 21 are in turn attached to a housing frame 24 surrounding the slide carriage, which is held by spring members 50 on the upper housing part 26. Instead of the rollers 36, sliding shoes could also be used, for example. According to the invention, the slide carriage 30 can be moved by the drive into an area lying outside the closed position, in which the guide tracks 21b in contact with the rollers 36 are lowered by a height h which relaxes the springs compared to the track in the operating state. These guideways 21b are inclined surfaces which cause a continuous increase in tensioning and a continuous reduction in spring tension when relaxing. After the inclined surfaces 21b, the guides 21 are interrupted by recesses 21c with a length greater than the roller diameter. As a result, the slide carriage 30 can be pivoted out of the housing and the regularly required replacement of the worn plates 22, 32 and of the interchangeable spout 34 can be carried out.
Die Federorgane 50 bestehen gemäss Fig. 2 aus einem zweiteiligen Bolzen 52 und einer im Gehäuseoberteil 26 angeordneten Feder 54 Der Bolzen 52 hat eine untere Anschlagfläche 52'. auf der der Gehäuserahmen 24 aufliegt, und eine obere Anschlagfläche 52' gegen die die Feder 54 drückt. Aus Montagezwecken ist er zweigeteilt und dabei ineinanderverschraubt. Beidseits des Gehäuserahmens 24 sind deren zwei Federorgane 50 symmetrisch und achsparallel zur Ausgussöffnung 15 und ein Bolzen 60 vorgesehen, der sich auf der Höhe der Ausgussöffnung befindet, in den Gehäuseoberteil 26 geschraubt ist und den Gehäuserahmen 24 zentriert, ihn mit seiner balligen Oberfläche jedoch allseitig gelenkig lässt. Die Federn sollen so bemessen sein, dass die Schieberplatte 32 mit einer vorgegebenen Spannkraft an die Bodenplatte 22 gepresst wird. An den Gehäuseoberteil 26 befestigte Abdeckbleche 58 schützen die Federorgane vor Verschmutzung. Die Schieberplatte 32 sowie die Bodenplatte 22 sind durch Spannmittel 38 bzw. 27 auf bekannte Art in der Schiebereinheit 30 bzw. im Gehäuseoberteil 26 gehalten.2, the spring members 50 consist of a two-part bolt 52 and a spring 54 arranged in the upper housing part 26. The bolt 52 has a lower stop surface 52 '. on which the housing frame 24 rests, and an upper stop surface 52 'against which the spring 54 presses. For assembly purposes, it is divided into two and screwed together. On both sides of the housing frame 24, the two spring members 50 are provided symmetrically and axially parallel to the pouring opening 15 and a bolt 60, which is located at the height of the pouring opening, is screwed into the upper housing part 26 and centers the housing frame 24, but with its spherical surface articulates it on all sides leaves. The springs should be dimensioned such that the slide plate 32 is pressed against the base plate 22 with a predetermined clamping force. Cover plates 58 fastened to the upper housing part 26 protect the spring elements against contamination. The slide plate 32 and the base plate 22 are held in a known manner in the slide unit 30 or in the upper housing part 26 by means of clamping means 38 or 27.
Nach dem Entleeren einer Pfanne 10 wird diese im Normalfall zwecks Wartung und Auswechslung der Verschleissteile zu einem Pfannenplatz gefahren. Dort wird sie so auf die Seite gelegt, dass die Schiebereinheit horizontal ausschwenkbar ist. Die nach dem Abgiessen in Schliessstellung gefahrene Schiebereinheit wird von einem am Pfannenplatz befindlichen Zylinder in die gemäss Fig. 3 gezeigte Stellung gefahren und bis zur strichpunktierten Position ausgeschwenkt, um die Verschlussplatten 22 und 32 ohne weiteres austauschen zu können. Sobald der Verschluss gewartet ist, wird er betriebsfertig gemacht und die Schiebereinheit wieder in Schliessstellung gebracht. Der auf der Giessbuhne zum Steuern des Verschlusses befindliche Hydraulikzylinder soll im Unterschied zu dem am Ptannenplatz nur eine Hublänge aufweisen, die die Schiebereinheit zwar von der Schliess- in die Offenstellung und umgekehrt bewegen kann, nicht aber in die ausserhalb der Schliessstellung liegende Position A. Falls auf der Giessbuhne und am Pfannenplatz derselbe Zylinder verwendet werden müsste, könnte ein am Gehäuse wegnehmbar befestigter Anschlag 25 vorgesehen sein, durch den die Schiebereinheit nicht in eine ausserhalb der Schliessstellung liegende Position A bewegbar wäre. Ein solcher Anschlag 25 ist andeutungsweise in Fig. 1 gezeigt. Dieser ist als Achse 25 ausgebildet und im Gehäuserahmen 24 herausziehbar gehalten.After a pan 10 has been emptied, it is normally moved to a pan location for the purpose of maintenance and replacement of the wearing parts. There it is placed on its side so that the slide unit can be swung out horizontally. The slide unit moved after the pouring into the closed position is moved into the position shown in FIG. 3 by a cylinder located at the pan position and swung out to the dot-dash position in order to be able to easily replace the closure plates 22 and 32. As soon as the lock has been serviced, it is made ready for operation and the slide unit is brought back into the closed position. In contrast to the hydraulic cylinder on the casting platform for controlling the breech, it should only have a stroke length that can move the slide unit from the closed to the open position and vice versa, but not to the position A. Outside the same cylinder would have to be used on the casting platform and at the ladle, a stop 25 which could be removably attached to the housing could be provided, by means of which the slide unit could not be moved into a position A lying outside the closed position. Such a stop 25 is indicated in Fig. 1. This is designed as an axis 25 and held extractable in the housing frame 24.
Bei einer in Fig. 4 gezeigten Variante einer Anlenkung der Schiebereinheit 80 weist diese beidseitig zwei Rollen 86, 86' auf. Die auf der Seite des Antriebsorganes gleichachsig angeordneten Rollen 86 sind in der ausserhalb der Schliessstellung S der Schiebereinheit 80 liegenden Position A durch in den Führungen 21 vorgesehenen Ausnehmungen 21' schiebbar. während die beiden gleichachsigen Rollen 86' gegenüberliegend in der genannten Position A von einer Nut 81' umgeben und zentriert sind. Dadurch, dass die Schiebereinheit 80 durch einen Gelenkhaken 89 an der Schubstange 28 des Antriebsorganes angelenkt ist. kann sie in der Position A um die Drehachse der Rollen 86' ausgeschwenkt werden.In a variant of a linkage of the slide unit 80 shown in FIG. 4, it has two rollers 86, 86 'on both sides. The rollers 86 arranged coaxially on the side of the drive element are in the outside of the The closed position S of the slide unit 80, position A, can be pushed through recesses 21 ′ provided in the guides 21. while the two coaxial rollers 86 'are surrounded and centered opposite one another in said position A by a groove 81'. Characterized in that the slide unit 80 is articulated by an articulated hook 89 on the push rod 28 of the drive element. it can be pivoted out in position A about the axis of rotation of the rollers 86 '.
Der in Fig. 5 gezeigte Schiebeverschluss 70 funktioniert im wesentlichen ähnlich wie der in Fig. 1 gezeigte. Es werden deshalb im folgenden nur die unterschiedlichen Merkmale dieses Verschlusses 70 gegenüber dem Verschluss 20 erläutert. Der ebenfalls an seinem einen Ende durch eine Gelenkverbindung 79 an der Schubstange 78 eines nicht dargestellten Antriebes verschwenkbar angelenkte Schieberwagen 50 mit beidseitig je zwei drehbar gelagerten Rollen 86 ist in einen am Gehäuse 76 ausschwenkbar angelenkten Deckel 74 verschiebbar gehalten.The slide closure 70 shown in FIG. 5 functions essentially similar to that shown in FIG. 1. Therefore, only the different features of this closure 70 compared to the closure 20 are explained below. The slide carriage 50, which is also pivotally articulated at one end by a joint 79 on the push rod 78 of a drive, not shown, with two rotatably mounted rollers 86 on each side, is slidably held in a cover 74 which is articulated on the housing 76 and can be swung out.
Der Schieberwagen 80 kann wiederum erfindungsgemäss vom Antrieb in einen ausserhalb der Schliessstellung S liegenden Bereich verschoben werden, in dem die mit den Rollen 86 in Berührung stehenden Führungsbahnen 71c gegenüber den im Betriebszustand befindlichen Bereich der Bahnen 71a um eine die Federn entspannende Höhe h abgesenkt sind. Die Führungsbahnen 71c verlaufen dabei parallel zu den Bahnen 71a und auch parallel zur Verschieberichtung des Schieberwagens 80. Schrägflächen 71b sorgen wiederum dafür, dass der Schieberwagen kontinuierlich ent- bzw. verspannt wird.According to the invention, the slide carriage 80 can in turn be moved by the drive into an area lying outside the closed position S, in which the guide tracks 71c in contact with the rollers 86 are lowered by a height h which relaxes the springs compared to the area of the tracks 71a which is in the operating state. The guide tracks 71c run parallel to the tracks 71a and also parallel to the direction of displacement of the slide carriage 80. Inclined surfaces 71b in turn ensure that the slide carriage is continuously relaxed or tensioned.
Der Deckel 74 ist auf bekannte Art mittels nicht näher gezeigten Spannorganen 75 an das Gehäuse 76 befestigt. Wie aus Fig. 6 ersichtlich ist, sind die Federorgane 90 im Schieberwagen 80 abgestützt und pressen im Betriebszustand des Verschlusses unmittelbar auf die Schieberplatte 82. Bei der Demontage des Verschlusses 70 wird der Schieberwagen zuerst in die entspannte Stellung gefahren, sodann kann der Deckel 74 vom Gehäuse 76 abgeschraubt und wie auch der Schieberwagen ausgeschwenkt, und es könn en dann die bereits genannten Wartungsarbeiten durchgeführt werden. Bei der Montage wird nach der Befestigung des Deckels 74 am Gehäuse 76 der Schieberwagen 80 durch eine Bewegung in Richtung der Offenstellung verspannt und in die Schliessstellung S gefahren. The cover 74 is fastened to the housing 76 in a known manner by means of tensioning elements 75 (not shown in more detail). As from Fig. 6 can be seen, the spring members 90 are supported in the slide carriage 80 and press directly on the slide plate 82 in the operating state of the closure. When the closure 70 is removed, the slide carriage is first moved into the relaxed position, then the cover 74 can be unscrewed from the housing 76 and how the slide carriage is also swung out, and the maintenance work already mentioned can then be carried out. During assembly, after the cover 74 is fastened to the housing 76, the slide carriage 80 is clamped by a movement in the direction of the open position and moved into the closed position S.
