Description

Verschlussplatte sowie ein Schiebeverschluss am Ausguss eines Metallschmelze enthaltenden Behälters  Closure plate and a sliding closure on the spout of a molten metal containing container
Die Erfindung betrifft eine Verschlussplatte für einen Schiebeverschluss am Ausguss eines Metallschmelze enthaltenden Behälters, bei der zwei äussere Längsseiten, eine auf einer mittigen Längsachse der Verschlussplatte angeordnete Durchflussöffnung und eine von letzterer ausgehende Schliessfläche vorgesehen sind; sowie ein Schiebeverschluss hiefür. The invention relates to a closure plate for a sliding closure at the spout of a molten metal containing container, in which two outer longitudinal sides, provided on a central longitudinal axis of the closure plate flow opening and provided by the latter closing surface are provided; and a sliding closure for this.
Gattungsmässige Verschlussplatten in einem Schiebeverschluss dienen für das öffnen und Schliessen des Durchlasses von Metallschmelze. Die Generic closure plates in a sliding closure serve to open and close the passage of molten metal. The
BESTÄTIGUNGSKOPIE jeweils mit einer Durchflussöffnung versehenen Verschlussplatten werden daher dichtend gegeneinander angepresst und durch einen Antrieb kann die eine Verschlussplatte über einen definierten Hub von der Offen- in eine Schliessstellung und umgekehrt bewegt werden. Somit bilden sich sowohl bei der oberen fixen wie auch bei der verschiebbaren Verschlussplatte Schliessflächen, deren Länge dem Verstellhub entspricht. Die Verschlussplatten werden entweder in die Mechanik des Schiebeverschlusses eingespannt, wie dies bei einem Schiebeverschluss gemäss der Druckschrift DE-A-35 22 134 vorgesehen ist, oder aber annähernd spielfrei in die Mechanik eingelegt, wie dies bei den in der Druckschrift EP-A-1 064 155 geoffenbarten Platten dargetan ist. CONFIRMATION COPY each provided with a flow opening closure plates are therefore sealingly pressed against each other and by a drive, the one closure plate over a defined stroke of the open in a closed position and vice versa are moved. Thus closing surfaces, the length of which corresponds to the adjustment stroke, form in both the upper fixed and the displaceable closure plate. The closure plates are either clamped in the mechanics of the sliding closure, as provided in a sliding closure according to the document DE-A-35 22 134, or inserted almost free of play in the mechanics, as in the in EP-A-1 064 155 disclosed plates.
Der vorliegenden Erfindung wurde die Aufgabe zugrundegelegt, eine Verschlussplatte nach der eingangs erwähnten Gattung zu schaffen, welche insbesondere bei einer aussenseitigen Verspannung mit einer minimalen Dimensionierung bzw. einer optimalen Verspannung versehen ist, so dass die Verschlussplatte eine hohe Sicherheit im Betrieb beim Verschliessen des Verschlusses bietet und dabei aber die äusseren Plattendimensionen im Verhältnis zum Durchmesser der Durchflussöffnung minimal gehalten werden. The present invention was based on the object to provide a closure plate according to the type mentioned, which is provided in particular at an external clamping with a minimum dimensioning or an optimal tension, so that the closure plate provides a high level of security in operation when closing the closure and while the outer plate dimensions are kept minimal in relation to the diameter of the flow opening.
Die Aufgabe ist erfindungsgemäss nach den Merkmalen des Anspruches 1 gelöst. The object is achieved according to the features of claim 1.
Diese Verschlusspiatte lässt sich mit ihrer erfindungsgemässen Ausbildung minimal dimensionieren, da sich durch diese an den beiden äusseren Längsseiten je mindestens zwei als Verspannflächen ausgebildeten Schulterflächen eine optimale Verspannung der Verschlussplatte errei- chen lässt. Dadurch, dass diese Schulterflächen eine Verjüngung der Platte bilden, kann die Verschlussplatte minimal dimensioniert werden. Dass diese bei den Verspannflächen auf der Seite der Schliessfläche anschliessenden, das Plattenende bildenden Aussenseiten zur Längsachse jeweils einen geringeren Winkel als die der Schulterflächen aufweisen, gewährleistet eine ausreichende Sicherheit auch bei einem mehrmaligen Einsatz der Verschlussplatten. This closure plate can be minimally dimensioned with its design according to the invention, since at least two shoulder surfaces, designed as clamping surfaces, on the two outer longitudinal sides thereof, achieve optimum clamping of the closure plate. leaves. The fact that these shoulder surfaces form a taper of the plate, the closure plate can be minimized. That these at the clamping surfaces on the side of the closing surface subsequent, the plate end forming outer sides to the longitudinal axis each have a smaller angle than that of the shoulder surfaces, ensures adequate security even with a repeated use of the closure plates.

Fig.1 zeigt ausschnittweise einen an einem Behälter montierten Schiebe- verschluss 10, wobei von dem Behälter nur der äussere Stahlmantel 11 mit einem Zentrierring 14, eine den Behälterauslass bildenden feuerfeste Einlaufhülse 13 und eine feuerfeste Auskleidung 12 angedeutet sind. Als Behälter ist normalerweise eine mit Stahlschmelze füllbare Pfanne einer Stranggiessanlage vorgesehen. Selbstverständlich kann es sich aber um einen beliebigen Metallschmelze aufnehmenden Behälter handeln. An diese Einlaufhülse 13 schliesst eine obere, im Gehäuse 14 des Schiebeverschlusses 10 befestigte feuerfeste Verschlussplatte 20 dicht an, welche mit einer verschiebbaren feuerfesten Verschlussplatte 22 in einer nicht näher gezeigten Schiebereinheit in Gleitkontakt steht, wobei die Schiebereinheit von einem Antrieb hin- und her bewegbar ist und zudem von nicht dargestellten Spannorganen am Gehäuse 14 befestigbar ist. Ferner schliesst an die verschiebbare Verschlussplatte 22 noch eine feuerfeste Ausgusshülse 16 an. 1 shows a detail of a sliding closure 10 mounted on a container, wherein only the outer steel jacket 11 with a centering ring 14, a refractory inlet sleeve 13 forming the container outlet, and a refractory lining 12 are indicated by the container. As a container usually fillable with molten steel pan of a continuous casting plant is provided. Of course, however, it may be a container receiving any molten metal. At this inlet sleeve 13 includes an upper, fixed in the housing 14 of the slide fastener 10 refractory closure plate 20 tightly, which is in sliding contact with a sliding refractory closure plate 22 in a slide unit not shown in detail, wherein the slide unit by a drive back and forth is movable and also by clamping members, not shown, on the housing 14 can be fastened. Furthermore, the refractable closure plate 22 is adjoined by a refractory spout 16.
In Fig. 2 ist die Verschlussplatte 20 gezeigt, welche aus einem Blechmantel 23 und aus einer in diesem eingemörtelten feuerfesten Platte 20' besteht. Sie weist zwei äussere Längsseiten, eine auf einer mittigen Längsachse A angeordnete Durchflussöffnung 21 sowie eine von letzterer ausgehende Schliessfläche S auf. Diese Schliessfläche S ist aus dem Durchmesser der Durchflussöffnung der gegenüberliegenden Verschlussplatte und aus dem Verstellhub der Schiebereinheit definiert. In Fig. 1 befindet sich der Schiebeverschluss 10 in Schliessposition, in der sich das Ende der Schliessfläche der unteren verschiebbaren Verschlussplatte 22 mit der Durchflussöffnung 21 der oberen Verschlussplatte 20 überdeckt. In Fig. 2, the closure plate 20 is shown, which consists of a metal jacket 23 and a mortared in this refractory plate 20 '. It has two outer longitudinal sides, a flow opening 21 arranged on a central longitudinal axis A and a closing surface S extending from the latter. This closing surface S is defined by the diameter of the flow opening of the opposite closure plate and by the adjustment stroke of the slide unit. In Fig. 1, the sliding closure 10 is in the closed position, in which the end of the closing surface of the lower sliding closure plate 22 with the flow opening 21 of the upper closure plate 20 overlaps.
Erfindungsgemäss sind an diesen beiden äusseren Längsseiten der Verschlussplatte 20 je zwei als Verspannflächen bzw. als Zentrierflächen dienende Schulterflächen 20a, 20b ausgebildet, welche zur Längsachse A einen Winkel α, ß aufweisen und dabei eine Plattenverjüngung bilden. Darüberhinaus weisen die Aussenseiten 20c, welche an die auf der Seite der Schliessfläche S befindlichen Schulterflächen 20a anschliessen, zur Längsachse jeweils einen geringeren Winkel γ als die der Schulterflächen 20a auf. According to the invention, on each of these two outer longitudinal sides of the closure plate 20, two shoulder surfaces 20a, 20b serving as clamping surfaces or as centering surfaces are formed which have an angle α, β relative to the longitudinal axis A and form a plate taper. In addition, the outer sides 20c, which adjoin the shoulder surfaces 20a located on the side of the closing surface S, to the Longitudinal axis each have a smaller angle γ than that of the shoulder surfaces 20a.
Diese Winkel α, ß bei den Längsseiten der Verschlussplatte 20 sind im vorliegenden Ausführungsbeispiel gleich dimensioniert, nämlich ca. 20°. Indes der Winkel γ der jeweiligen Aussenseite 20c beträgt vorzugsweise zwischen 0 bis 20°, vorliegend ca. 5°. in Bezug auf die Längsachse A ist die Verschlussplatte 20 ferner symmetrisch ausgebildet, womit auf beiden Längsseiten gleiche Winkel und gleiche Abmessungen vorliegen. These angles α, ß in the longitudinal sides of the closure plate 20 are the same dimensioned in the present embodiment, namely about 20 °. However, the angle γ of the respective outside 20c is preferably between 0 and 20 °, in the present case about 5 °. with respect to the longitudinal axis A, the closure plate 20 is further formed symmetrically, so that there are equal angles and dimensions on both longitudinal sides.
Diese mit dem Winkel α, ß zur Längsachse A versehenen Schulterflächen 20a, 20b der Verschlussplatte 20 sind in einem Abstand 27a, 27b zur Querachse der Durchflussöffnung 21 angeordnet. Die auf die Schulterflächen 20a, 20b im betrieblichen Zustand wirkenden Spannelemente 17a, 17b, welche zum Schiebeverschluss 10 gehören und daher strichpunktiert angedeutet sind, erzeugen eine senkrecht zu der jeweiligen Schulterfläche 20a, 20b gegen die Plattenmitte hin verlaufende resultierende Spannkraftlinie 25a, 25b, welche die Längsachse A beim Schnittpunkt 26a, 26b schneidet. These shoulder surfaces 20a, 20b of the closure plate 20 provided with the angle α, β with respect to the longitudinal axis A are arranged at a distance 27a, 27b to the transverse axis of the throughflow opening 21. The tension elements 17a, 17b which act on the shoulder surfaces 20a, 20b and belong to the sliding closure 10 and are therefore indicated by dot-dash lines, produce a resultant tension line 25a, 25b which runs perpendicular to the respective shoulder surface 20a, 20b against the center of the plate Longitudinal axis A at the intersection 26a, 26b intersects.
Vorteilhaft liegt im Rahmen der Erfindung der von dieser jeweiligen Spannkraftlinie 25a, 25b und der Längsachse A gebildete Schnittpunkt 26a, 26b in einem bestimmten Abstand 27a, 27b zum Aussendurchmes- ser der Durchflussöffnung 21. Dieser Abstand entspricht in der Regel maximal zweimal dem Durchmesser der Durchflussöffnung 21 und ist auf der Seite der Schliessfläche S grösser als gegenüberliegend. In Fig. 2 ist dieser Abstand kleiner als dieser Durchmesser der Durchflussöffnung veranschaulicht. Mit diesem Abstand 27a, 27b der Schulterflächen 20a, 20b zur Querachse der Durchflussöffnung 21 entsteht ein erheblicher Vorteil insofern, als die im Bereich um die Durchflussöffnung herum wirkenden Verspan- nungskräfte die durch die Hitzebelastung entstehenden Risse im Feuerfestmaterial um die Durchflussöffnung herum nicht zum Ausbrechen des Feuerfestmateriales führen. Diese Rissbildung in der feuerfesten Platte 20' kann aber mit dieser erfindungsgemässen Verspannung gezielt be- einflusst werden, so dass sich die Haltbarkeit der Platte entscheidend verbessert. Advantageously, within the scope of the invention, the intersection point 26a, 26b formed by this respective clamping force line 25a, 25b and the longitudinal axis A lies at a specific distance 27a, 27b to the outside diameter of the flow opening 21. This distance generally corresponds at most twice to the diameter of the flow opening 21 and is larger on the side of the closing surface S than opposite. In Fig. 2, this distance is smaller than this diameter of the flow opening illustrated. With this distance 27a, 27b of the shoulder surfaces 20a, 20b to the transverse axis of the flow opening 21, a considerable advantage arises in that the forces acting in the area around the flow opening do not break the cracks in the refractory material around the flow opening caused by the heat load Refractory lead. However, this cracking in the refractory plate 20 'can be influenced in a targeted manner with this clamping according to the invention, so that the durability of the plate is decisively improved.
Ferner sind die Enden der Verschlussplatte 20 in herkömmlicherweise jeweils durch zwei Radien gebildet, welche je von der Aussenseite 20c bzw. von der Schulterfläche 20b ausgehen. Zudem sind die äusseren Längsseiten im Bereich 28 zwischen den Schulterflächen parallel zur Längsachse angeordnet. Im Prinzip könnten diese auch eine ovale oder ähnliche Form haben. Furthermore, the ends of the closure plate 20 are conventionally formed in each case by two radii, which respectively emanate from the outer side 20c and from the shoulder surface 20b. In addition, the outer longitudinal sides are arranged in the region 28 between the shoulder surfaces parallel to the longitudinal axis. In principle, these could also have an oval or similar shape.
Fig. 3 zeigt eine aus einer Platte und einem Blechmantel bestehenden Verschlussplatte 30, welche ähnlich wie diejenige nach Fig. 2 ausgebildet ist und daher nachfolgend nurmehr die Unterschiede erläutert sind. Es sind wiederum beiden äusseren Längsseiten je zwei Schulterflächen 30a, 30b symmetrisch zur Längsachse A zugeordnet. Anschliessend an die beiden Schulterflächen 30b auf der von der Schliessfläche S abgekehrten Seite sind Aussenseiten 30d vorgesehen, welche zur Längsachse A jeweils einen geringeren Winkel als die der Schulterflächen 30b aufweisen. Diese Aussenseiten 30d verlaufen wie die gegenüberliegend an die Schulterflächen 30a anschliessenden Aussenseiten 30c annä- hernd parallel zur Längsachse A. Diese Aussenseiten 30c, 30d beidseitig zu den Schulterflächen bilden eine gleiche Plattenbreite. Die beiden Enden bei der Verschlussplatte sind je halbkreisförmig ausgebildet. Fig. 3 shows a consisting of a plate and a metal jacket closure plate 30 which is similar to that of FIG. 2 is formed and therefore only the differences are explained below. In turn, two outer longitudinal sides each have two shoulder surfaces 30a, 30b assigned symmetrically to the longitudinal axis A. Subsequently to the two shoulder surfaces 30b on the side facing away from the closing surface S side outer sides 30d are provided, which each have a smaller angle to the longitudinal axis A than that of the shoulder surfaces 30b. These outer sides 30d run like the outer sides 30c which adjoin the shoulder surfaces 30a on the opposite side. Hernd parallel to the longitudinal axis A. These outer sides 30c, 30d on both sides of the shoulder surfaces form a same plate width. The two ends in the closure plate are each formed semicircular.
Die Verschlussplatte 40 nach Fig. 4 ist wiederum ähnlich wie diejenige nach Fig. 2 ausgebildet ist und es sind nachfolgend die Unterschiede dargetan. Die Schulterflächen 40a sind nicht als gerade Flächen, sondern als runde Flächen ausgebildet. Der Radius 40r ist dabei so gewählt, dass er gleichsam den Radius des Plattenendes 40e bildet. Damit könnte die Verschlussplatte 40 in ein kreisförmige Ausnehmung bei der Mechanik des Schiebeverschlusses eingelegt sein, ohne dass eine Verspan- nung erfolgt. The closure plate 40 of FIG. 4 is again similar to that of FIG. 2 is formed and there are shown below the differences. The shoulder surfaces 40a are not formed as straight surfaces but as round surfaces. The radius 40r is chosen so that it forms the radius of the plate end 40e as it were. Thus, the closure plate 40 could be inserted into a circular recess in the mechanism of the slide fastener, without any distortion occurs.
In Fig. 5 ist eine Verschlussplatte 50 dargestellt, bei welcher als Besonderheit die Schulterflächen 50a, 50b bei den äusseren Längsseiten rechtwinklig zur Längsachse A angeordnet sind, so dass diese Winkel a, ß 90° betragen. Diese Schulterflächen 50a, 50b sind vorzugsweise mit einer kurzen Länge von nur einigen Millimetern dimensioniert, während bei den obigen Varianten die Schulterflächen jeweils eine Länge von vorzugsweise 30 bis 100 mm aufweisen. Diese Verschlussplatte 50 eignet sich speziell dafür, annähernd spielfrei ohne Verspannung in die Mechanik des Schiebeverschlusses eingelegt zu werden. Bei der Mechanik müssten entsprechende Ausnehmungen vorgesehen sein, in welche diese Zentrierschultern 51 mit den an diesen ausgebildeten Schulterflächen 50a, 50b annähernd spielfrei aufgenommen würden. Die Zentrierschultern 51 mit ihren Schulterflächen 50a, 50b sind durch den die feuerfeste Platte 50' umgebenden Blechmantel 52 gebildet. Diese vorzugsweise mit einer kurzen Länge von nur einigen Millimetern dimensionierten Schulterflächen 50a, 50b könnten aber auch mit weniger als 90° zur Längsachse A ausgebildet sein. In Fig. 5, a closure plate 50 is shown in which as a special feature the shoulder surfaces 50a, 50b are arranged at the outer longitudinal sides perpendicular to the longitudinal axis A, so that these angles a, ß amount to 90 °. These shoulder surfaces 50a, 50b are preferably dimensioned with a short length of only a few millimeters, while in the above variants, the shoulder surfaces each have a length of preferably 30 to 100 mm. This closure plate 50 is particularly suitable for being inserted into the mechanics of the slide fastener almost without play, without any tension. In the case of mechanics, corresponding recesses would have to be provided, in which these centering shoulders 51 would be received approximately free of play with the shoulder surfaces 50a, 50b formed on them. The centering shoulders 51 with their shoulder surfaces 50a, 50b are formed by the sheet-metal jacket 52 surrounding the refractory plate 50 '. These preferably with a short length of only a few millimeters dimensioned shoulder surfaces 50a, 50b could also be formed with less than 90 ° to the longitudinal axis A.
Die Erfindung ist mit den obigen Ausführungsbeispielen ausreichend dargetan. Es könnten aber noch weitere Varianten vorgesehen sein. So könnte beispielsweise statt ein Blechmantel auch nur ein die Platte umgebender Blechreif, oder die Platte könnte auch unmittelbar in die Mechanik des Schiebeverschlusses eingelegt und ggf. darin verspannt werden. The invention is sufficiently demonstrated with the above embodiments. But it could be provided even more variants. Thus, for example, instead of a metal jacket even a sheet metal surrounding the plate, or the plate could also be inserted directly into the mechanics of the sliding closure and possibly clamped therein.
Theoretisch könnte zumindest die eine der Schulterflächen auf der einen Längsseite zu der korrespondierenden auf der andern Längsseite verschieden lang oder mit einem unterschiedlichen Winkel versehen sein. Dies könnte den Vorteil bieten, dass wenn die Verschlussplatten nach einer bestimmten Anzahl von Entleerungen des Behälters gewendet und damit die hintere Seite zur Gleitfläche wird, dass diese zuerst als Schieberplatte und nach dem Wenden nur als Bodenplatte verwendet werden kann. Theoretically, at least one of the shoulder surfaces could be provided on the one longitudinal side to the corresponding on the other longitudinal side of different lengths or with a different angle. This could offer the advantage that when the closure plates are turned after a certain number of emptying of the container and thus the rear side becomes the sliding surface, that it can be used first as a slide plate and after turning only as a base plate.
