Description

Die Erfindung betrifft einen Gießpfannenschieber gemäß Patentanspruch 1. Spezifizierte Ausgestaltungen sind in den unterausprüchen 2-15 angegeben.The invention relates to a ladle slide according to Claim 1. Specified configurations are in the indicated under expressions 2-15.

Aus der FR-A-2 277 644 ist ein Gießpfannenschieber bekannt, der aus einem Gehäuse, einer ortsfest montierten Kopfplatte und einer relativ dazu verschiebbaren Schieberplatte, die zu diesem Zweck innerhalb eines relativ zum Gehäuse verschiebbaren Gleitrahmens gehalten ist, besteht.A ladle slide is known from FR-A-2 277 644, that of a housing, a stationary head plate and a slide plate that can be moved relative to it and that closes this purpose within a displaceable relative to the housing The sliding frame is held.

Ferner ist es bekannt, die Schieberplatte mittels Federelementen gegen die Kopfplatte zu drücken. Nur beispielhaft wird dazu auf die Broschüre der Anmelderin mit dem Titel "Sliding Gate Valve Systems for Ladles" mit Veröffentlichungsvermerk "Cat.-No. 401.1-05.89-P2000E" verwiesen.It is also known that the slide plate by means of spring elements to press against the headstock. Will only be exemplary on the applicant's brochure entitled "Sliding Gate Valve Systems for Ladles "with release note "Cat.-No. 401.1-05.89-P2000E".

Des weiteren wird diesbezüglich auf Fig. 5 hingewiesen, die einen Teil eines herkömmlichen Gießpfannenschiebers im Längsschnitt zeigt. Dieser Gießpfannenschieber ist gekennzeichnet durch eine an der Unterseite des nicht näher dargestellten Gießgefäßes befestigte Montageplatte 1, innerhalb der ein aus Feuerfest-Material bestehender Wechselring 34 plaziert ist, ein Schiebergehäuse 2, einen Gleitrahmen 5 sowie durch eine ortsfeste Kopfplatte K2 und eine relativ dazu verschiebbare Schieberplatte K1. Das Schiebergehäuse 2 ist aus seitlichen Begrenzungswänden 6 und einer Bodenplatte 3 zusammengesetzt. Der Gleitrahmen 5 umfaßt eine sich parallel zur Schieberplatte K1 erstreckende Platte 8 mit hülsenartigen Aufnahmetaschen 9 zur Aufnahme von thermodynamischen Federelementen 10, die sich an der Unterseite der Schieberplatte K1 einerseits und an der Bodenplatte 4 des Gleitrahmens 5 andererseits abstützen unter entsprechender Andrückung der Schieberplatte K1 gegen die Kopfplatte K2. An der schieberplattenseitigen Seite der Bodenplatte 4 des Gleitrahmens 5 sind den thermodynamischen Federelementen 10 topfartige Ausnehmungen 12 zugeordnet, in die sich ein axialer Fortsatz der thermodynamischen Federelemente 10 hineinerstrecken kann. Die Abstützung der thermodynamischen Federelemente 10 erfolgt am oberen Rand der Ausnehmungen 12 über eine Stützscheibe 13.In this regard, reference is also made to FIG. 5, which a part of a conventional ladle slide in longitudinal section shows. This ladle slide is marked by one at the bottom of the not shown Casting vessel attached mounting plate 1, inside of a Refractory material existing exchange ring 34 is placed, a slide housing 2, a slide frame 5 and by a stationary head plate K2 and a slidable relative to it Slider plate K1. The slide housing 2 is from the side Boundary walls 6 and a bottom plate 3 assembled. The sliding frame 5 comprises a parallel to the slide plate K1 extending plate 8 with sleeve-like receiving pockets 9 for receiving thermodynamic spring elements 10, located on the underside of the slide plate K1 on the one hand and on the bottom plate 4 of the slide frame 5 on the other hand support by pressing the slide plate accordingly K1 against the head plate K2. On the slide plate side Side of the bottom plate 4 of the slide frame 5 are the thermodynamic spring elements 10 pot-like recesses 12 associated with an axial extension of the thermodynamic Spring elements 10 can extend into it. The The thermodynamic spring elements 10 are supported on upper edge of the recesses 12 via a support disk 13.

Die Schieberplatte ist samt Gehäuse 2 und Gleitrahmen 5 gegenüber der Kopfplatte K2 abschwenkbar. Die dieser Schwenkmechanik zugeordnete Schließvorrichtung ist in Fig. 4 mit der Bezugsziffer 11 gekennzeichnet.The slide plate is complete with housing 2 and slide frame 5 pivotable relative to the head plate K2. This swivel mechanism associated locking device is in Fig. 4 with the Reference number 11 marked.

Unterhalb des Gehäuses 2 erstreckt sich noch eine wärmedämmende Schutzplatte 7.Below the housing 2 there is also a heat-insulating one Protection plate 7.

Der Gleitrahmen 5 ist innerhalb des Gehäuses 2 längsverschieblich gelagert. Zu diesem Zweck umfaßt die Bodenplatte 3 des Gehäuses 2 innenseitig flachbandartige Gleitschienen 14, während die Bodenplatte 4 des Gleitrahmens 5 außenseitig bzw. an ihrer Unterseite zugeordnete ebenfalls flachbandartige Gleitschienen 15 aufweist. Diese beiden Gleitschienen 14, 15 definieren auch einen geringen Spalt 16 zwischen der Unterseite der Bodenplatte 4 des Gleitrahmens 5 und der Innen-bzw. Oberseite der Bodenplatte 3 des Gehäuses 2.The sliding frame 5 is longitudinally displaceable within the housing 2 stored. For this purpose, the base plate 3 of the housing 2 on the inside flat band-like slide rails 14, while the base plate 4 of the slide frame 5 on the outside or on the underside also assigned flat ribbon-like Has slide rails 15. These two slide rails 14, 15 also define a small gap 16 between the bottom the bottom plate 4 of the slide frame 5 and the inner or. Top of the base plate 3 of the housing 2.

In der Praxis hat sich gezeigt, daß aus dem Feuerfest-Material insbesondere der Schieberplatte während des Betriebes Teerbestandteile entweichen, die innerhalb des Gleitrahmens und Gehäuses nach unten abtropfen. Dabei werden die Taschen 9 für die Aufnahme der thermodynamischen Federelemente 10 zugesetzt. Auch die durch die Gleitschienen 14, 15 definierten Gleitflächen verschmutzen. In der Regel bestehen die Gleitschienen 14, 15 aus Bronze. Teer setzt sich dort ab mit der Folge, daß die Gleitflächen klebrig werden. Die weitere Folge ist, daß der Gleitrahmen 5 nicht mehr ruckfrei hin- und herbewegt werden kann. Die Präzision des Schiebers geht im Laufe des Betriebes dadurch verloren. In practice it has been shown that the refractory material especially the slide plate during operation Tar components escape inside the slide frame and drain the housing downwards. The pockets 9 added for receiving the thermodynamic spring elements 10. Also those defined by the slide rails 14, 15 Soiling sliding surfaces. As a rule, the slide rails exist 14, 15 made of bronze. Tar settles there with the Consequence that the sliding surfaces become sticky. The further episode is that the sliding frame 5 no longer moves back and forth smoothly can be. The precision of the slide goes in the course of the company lost.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die vorgenannten Verschmutzungsprobleme zu vermeiden und damit einen dauerhaft präzisen Betrieb des Schiebers zu gewährleisten.The present invention is based on the object to avoid the aforementioned pollution problems and thus to ensure permanent, precise operation of the slide.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst. Der Kern der vorliegenden Erfindung liegt also darin, daß die Gleitflächen außerhalb des verschmutzungskritischen Bereichs liegen. Dadurch ist ein dauerhaft präziser Betrieb gewährleistet.This task is characterized by the characteristics of the Claim 1 solved. The essence of the present invention is therefore that the sliding surfaces outside the contamination-critical area. This is a Guaranteed permanent, precise operation.

Von wesentlicher Bedeutung für die Erfindung ist die Maßnahme, daß der Gleitrahmen einstückig ausgebildet ist, wobei der Boden eine Art Stegrost definiert. Dadurch wird eine gesonderte Bodenplatte sowohl für den Gleitrahmen als auch für das Gehäuse entbehrlich. Durch die durch den Stegrost gebildeten Bodenöffnungen kann der von der Schieberplatte stammende Teer nach unten abtropfen, ohne daß irgendwelche Schieberteile, insbesondere bewegten Teile verschmutzt werden. Gleiches gilt, wenn der Boden durch den Federelementen zugeordnete Stützstege oder -platten definiert, im übrigen aber ebenfalls offen ausgebildet ist.Essential for the invention is the measure that the slide frame is integrally formed, wherein the floor defines a kind of footbridge. This makes a separate one Base plate for both the sliding frame and for the housing can be dispensed with. By the formed by the web grate Bottom openings can be the one from the slide plate Drip tar down without any slider parts, especially moving parts become dirty. The same applies if the floor is assigned by the spring elements Support webs or plates defined, but otherwise is also open.

Des weiteren ist von besonderer Bedeutung die Lochplatten-Konstruktion für die thermodynamischen Federelemente, da diese Konstruktion einen einfachen Ein- und Ausbau der thermodynamischen Federelemente einerseits sowie insbesondere einen einfachen Austausch derselben als Baueinheit erlaubt. Vor allem kann dadurch auch das Positionsmuster der thermodynamischen Federelemente in einfacher Weise verändert werden, nämlich durch Verwendung von Lochplatten mit unterschiedlich angeordneter Lochung für die thermodynamischen Federelemente. Auch entfallen im Vergleich zum Stand der Technik die verschmutzungsintensiven Aufnahmetaschen für die thermodynamischen Federelemente sowie die Stützscheiben dür die Abstützung derselben an der Bodenplatte des Gleitrahmens. Die thermodynamischen Federelemente sind erfindungs gemäß so positioniert, daß sie sich an den Knoten- bzw. Kreuzungspunkten der den stegrostartigen Boden definierenden Stege des Gleitrahmens abstützen.The perforated plate construction is also of particular importance for the thermodynamic spring elements, because this construction makes it easy to install and remove the thermodynamic Spring elements on the one hand and in particular allows simple replacement of the same as a structural unit. Above all, this can also change the position pattern of the thermodynamic Spring elements can be changed in a simple manner, namely by using perforated plates with different arranged perforation for the thermodynamic Spring elements. Compared to the state of the Technology the pollution-intensive pockets for the thermodynamic spring elements and the supporting discs the support of the same on the base plate of the slide frame. The thermodynamic spring elements are fiction positioned in such a way that they adhere to the nodes or Crossing points of the floor that defines the stewed grate Support webs of the slide frame.

Wie den Fig. 1 und 2 sehr gut entnommen werden kann, ist der Gleitrahmen, innerhalb dem die Schieberplatte k1 positioniert ist, nach Art eines Troges ausgebildet, dessen obere Längsränder 17 seitlich nach außen vorstehen und an ihren Unterseiten Gleitflächen 18 aufweisen, die im Betrieb mit gehäuseseitigen Gleitflächen 19 korrespondieren. In den Fig. 1 und 2 ist der trogfärmige Gleitrahmen mit der Bezugsziffer 20 gekennzeichnet. Des weiteren begrenzen bei der dargestellten Ausführungsform die Gleitflächen 18 und 19 jeweils V-förmige Nuten, zwischen denen ein Gleitstab 21 angeordnet ist, der einen etwa quadratischen Querschnitt aufweist. Dieser Gleitstab besteht vorzugsweise aus hochgleitfähigem Material, z. B. Bronze oder dergleichen. 1 and 2 can be seen very well, is the Sliding frame within which the slide plate k1 is positioned is designed in the manner of a trough, the upper longitudinal edges 17 protrude laterally and on their undersides Have sliding surfaces 18 which are in operation with the housing Slide surfaces 19 correspond. 1 and 2 is the trough-shaped sliding frame with the reference number 20 characterized. Furthermore, limit the shown Embodiment, the sliding surfaces 18 and 19 each V-shaped Grooves, between which a slide rod 21 is arranged, the has an approximately square cross section. This slide bar preferably consists of highly slidable material, e.g. B. bronze or the like.

Es ist natürlich genausogut denkbar und herstellungstechnisch sogar bevorzugt, die Gleitflächen 18, 19 durch flachbandartige Gleitschienen entsprechend den Gleitschienen beim Stand der Technik zu definieren. In diesem Fall sind die gleitrahmenseitigen Gleitflächen 18 durch an den Unterseiten der seitlich vorstehenden Längsränder angeordnete Gleitschienen bestimmt, während die gehäuseseitigen Gleitflächen 19 durch an der zugekehrten Oberseite des Gehäuses 22 angeordnete Gleitschienen definiert sind. Das Gehäuse 22 ist bei der in Fig. 1 dargestellten Ausführungsform auf ein rechteckförmiges Hohlkastenprofil reduziert. Eine Gehäuse-Bodenplatte ist entbehrlich. Auch fehlt bei der konkreten Ausführungsform eine gesonderte Gleitrahmen-Bodenplatte, da der Gleitrahmen als einstückiges Stahlgußteil hergestellt ist. Wie insbesondere der Fig. 2 gut entnommen werden kann, ist der Boden 23 des trogförmigen Gleitrahmens 20 nach Art eines Stegrostes ausgebildet. Die auch hier vorhandenen thermodynamischen Federelemente 10, durch die im Betrieb die Schieberplatte K1 gegen die Kopfplatte K2 gedrückt wird, stützen sich gleitrahmenseitig an den Knoten- bzw. Kreuzungspunkten 24 der den stegrostartigen Boden 23 definierenden Stege 25 ab. Dadurch werden den Federelementen zugeordnete Stützscheiben entbehrlich, wie sie z. B. beim Stand der Technik nach Fig. 4 notwendig sind. Zwischen der Schieberplatte K1 und den diese gegen die Kopfplatte K2 drückenden thermodynamischen Federelementen 10 ist noch eine Druckplatte 26 angeordnet, an der sich die erwähnten Federelemente 10 schieberplattenseitig abstützen. Die thermodynamischen Federelemente 10 sind also zwischen der Druckplatte 26 und dem Boden 23 des trogförmigen Gleitrahmens 20 wirksam.Of course, it is just as conceivable and technically feasible even preferred, the sliding surfaces 18, 19 by flat ribbon-like Slide rails according to the slide rails when standing of technology. In this case, the sliding frame side Sliding surfaces 18 through on the undersides of the laterally projecting longitudinal edges arranged slide rails determined, while the housing-side sliding surfaces 19 through arranged on the facing top of the housing 22 Slide rails are defined. The housing 22 is in the Fig. 1 shown embodiment on a rectangular Hollow box profile reduced. A housing base plate is not necessary. There is also no one in the specific embodiment separate sliding frame base plate, as the sliding frame as one-piece steel casting is made. How in particular 2 can be seen well, the bottom 23 of the trough-shaped sliding frame 20 designed in the manner of a web grate. The thermodynamic spring elements also present here 10, against the slide plate K1 during operation the head plate K2 is pressed, support on the sliding frame side at the nodes or intersection points 24 of the web rust-like Bottom 23 defining webs 25. This will support discs associated with the spring elements can be dispensed with, such as they z. B. in the prior art of FIG. 4 are necessary. Between the slide plate K1 and this against the head plate K2 pressing thermodynamic spring elements 10 still arranged a pressure plate 26 on which the mentioned Support spring elements 10 on the slide plate side. The thermodynamic spring elements 10 are therefore between the Pressure plate 26 and the bottom 23 of the trough-shaped slide frame 20 effective.

Von besonderer Bedeutung ist noch, daß die thermodynamischen Federelemente 10 durch eine sich parallel zum Boden 23 des trogförmigen Gleitrahmens 20 bzw. parallel zur Schieberplatte K1 oder auch parallel zur Druckplatte 26 erstreckende Lochplatte 27 in Position gehalten sind. Die thermodynamischen Federelemente 10 können in den Löchern 28 der Lochplatte 27 klemmend gehalten sein, so daß die Federelemente 10 samt Lochplatte 27 als Baueinheit montierbar, demontierbar bzw. austauschbar sind, ohne daß die Gefahr besteht, daß sie aus der Lochplatte bzw. aus den Löchern 28 derselben herausfallen.Of particular importance is that the thermodynamic Spring elements 10 by a parallel to the bottom 23 of the trough-shaped slide frame 20 or parallel to the slide plate K1 or perforated plate extending parallel to the pressure plate 26 27 are held in position. The thermodynamic Spring elements 10 can be in the holes 28 of the perforated plate 27th be held clamped so that the spring elements 10 together Perforated plate 27 can be assembled, dismantled or are interchangeable without the risk of them being out the perforated plate or fall out of the holes 28 thereof.

Die Montageeinheit "Lochplatte 27/Federelemente 10" ist hinsichtlich der Handhabung höchst bedienerfreundlich. Es können Lochplatten mit nach unterschiedlichen Muster angeordneten Löchern bereitgestellt werden, die bei Bedarf nach entsprechender Bestückung mit Federelementen lediglich ausgetauscht zu werden brauchen. Natürlich sind die Löcher 28 der Lochplatte 27 stets Kreuzungspunkten 24 im Boden 23 des Gleitrahmens 20 zugeordnet.The assembly unit "perforated plate 27 / spring elements 10" is regarding handling extremely user-friendly. It can Perforated plates with different patterns Holes will be provided, if necessary after appropriate Equipped with spring elements only exchanged need to be. Of course, the holes 28 of the perforated plate 27 always crossing points 24 in the bottom 23 of the slide frame 20 assigned.

Die Lochplatte 27 erstreckt sich bei der dargestellten Ausführungsform in nur geringem Abstand von der Druckplatte 26 parallel zu dieser.The perforated plate 27 extends in the illustrated embodiment at a short distance from the pressure plate 26 parallel to this.

Um auch nur die geringste Gefahr einer Verschmutzung der Gleitflächen 18 und 19 zwischen Gleitrahmen 20 und Gehäuse 22 durch Teer oder dergleichen zu vermeiden, liegen die erwähnten Gleitflächen etwa auf Höhe der Schieberplatte K1, und zwar - wie bereits erwähnt - außerhalb des Gleitrahmehs 20. Der unvermeidliche Teer, der im Betrieb vom Feuerfest-Material der Kopf- und/oder Schieberplatte abgeschieden wird, kann durch die Öffnungen 28 im Boden 23 des Gleitrahmens 20 hindurch nach außen entweichen bzw. abtropfen. 'Die Bodenöffnungen 28 werden zwischen den Bodenstegen 25 definiert.To even the slightest risk of pollution Slide surfaces 18 and 19 between slide frame 20 and housing 22 to avoid by tar or the like, are the mentioned Sliding surfaces approximately at the level of the slide plate K1, and although - as already mentioned - outside of the sliding frame 20. The inevitable tar that is in operation from the refractory material the top and / or slide plate is separated, can through the openings 28 in the bottom 23 of the slide frame 20th escape or drip out through it. 'The floor openings 28 are defined between the webs 25.

Entsprechend Fig. 3 kann die Lochplatte 27 in Position relativ zur Druckplatte 26 durch eine Keilverriegelung 29 gehalten sein. Diese ist durch eine an der Unterseite der Druckplatte 26 angeordnete Lasche 30 mit Queröffnung 31 einerseits und einen in die Queröffnung 31 einführbaren Keil 32 andererseits definiert. Die Lasche 30 erstreckt sich im montierten Zustand durch eine entsprechende Öffnung 33 in der Lochplatte 27 hindurch. Der Keil 32 ist als Flachkeil ausgebildet und dient zur klemmenden Verriegelung der Lochplatte 27 relativ zur Druckplatte 26. Der Abstand zwischen Lochplatte 27 und Druckplatte 26 wird durch einen radial vorstehenden Umfangsrand 34 an der der Schieberplatte K1 zugewandten Seite der thermodynamischen Federelemente 10 definiert. Dieser Umfangsrand 34 weist einen Durchmesser auf, der größer ist als der Innendurchmesser der den Federelementen 10 zugeordneten Löcher 28 in der Lochplatte 27. Im montierten Zustand erstreckt sich der Umfangsrand 34 zwischen der Lochplatte 27 und der Druckplatte 26 so wie dies in Fig. 1 dargestellt ist. Mittels des Flachkeils 33 wird die Lochplatte 27 gegen die Umfangsränder 34 der thermodynamischen Federelemente 10 gepreßt, und damit in einem durch die Höhe der Umfangsränder 34 bestimmten Abstand von der Druckplatte 26 gehalten. Vorzugsweise sind zwei Keilverriegelungen 29 der beschriebenen Art vorgesehen, und zwar jeweils an zwei gegenüberliegenden Enden der Lochplatte 27.3, the perforated plate 27 can be relatively in position held to the pressure plate 26 by a wedge lock 29 his. This is through one on the bottom of the pressure plate 26 arranged tab 30 with transverse opening 31 on the one hand and a wedge 32 that can be inserted into the transverse opening 31 Are defined. The tab 30 extends in the assembled Condition through a corresponding opening 33 in the perforated plate 27 through. The wedge 32 is designed as a flat wedge and serves to clamp the perforated plate 27 relatively to the pressure plate 26. The distance between perforated plate 27 and Pressure plate 26 is by a radially protruding peripheral edge 34 on the side of the slide plate K1 facing the thermodynamic spring elements 10 defined. This peripheral edge 34 has a diameter that is larger than that Inner diameter of the spring elements 10 assigned Holes 28 in the perforated plate 27. In the assembled state extends the peripheral edge 34 between the perforated plate 27 and the pressure plate 26 as shown in FIG. 1. By means of the flat wedge 33, the perforated plate 27 is against the Circumferential edges 34 of the thermodynamic spring elements 10 pressed, and thus in one by the height of the peripheral edges 34 held certain distance from the pressure plate 26. Preferably are two wedge locks 29 of the described Art provided, each on two opposite Ends of perforated plate 27.

Statt der beschriebenen Keilverriegelung ist auch eine Schraubverbindung der Lochplatte 27 mit der Druckplatte 26 möglich. Des weiteren sind statt der beschriebenen thermodynamischen Federelemente auch reine Stahlfederpakete, wie Schrauben- oder Tellerfedern, denkbar.Instead of the wedge lock described is also Screw connection of the perforated plate 27 with the pressure plate 26 possible. Furthermore, instead of the thermodynamic described Spring elements also pure steel spring packages, such as Coil or disc springs, conceivable.

In Fig. 4 ist ein Schieber in Unteransicht dargestellt, wobei Teile, die bereits anhand der vorangehenden Figuren beschrieben sind, in Fig. 4 mit denselben Bezugsziffern versehen sind. Diese Ausführungsform unterscheidet sich von der vorbeschriebenen Konstruktion zum einen dadurch, daß der Gleitrahmen 20 eine Stahlplatten-Schweißkonstruktion ist, und zu anderen dadurch, daß der Boden 23 des Gleitrahmens durch die Bodenfläche nur im Wirkbereich der Federelemente 10 zur gleitrahmenseitigen Abstützung derselben bedeckende Stützstege bzw. Stegplatte 35 definiert ist. Diese Platte umfaßt ein zentrales Fenster 36, in dessen Bereich keine Federelemente 10 angeordnet sind. Auch die übrigen Bereiche 37, 38 des Bodens, in dem keine Federelemente 10 wirksam sind, ist offen, so daß Teer oder dgl. ungehindert nach unten abtropfen kann.In Fig. 4, a slide is shown in bottom view, wherein Parts already described with reference to the previous figures are provided with the same reference numerals in FIG. 4 are. This embodiment differs from the one described above Construction on the one hand in that the sliding frame 20 is a steel plate welded construction, and too other in that the bottom 23 of the sliding frame through the Floor area only in the effective area of the spring elements 10 Support webs covering the sliding frame side of the same or web plate 35 is defined. This plate includes a central window 36, in the area of which no spring elements 10 are arranged. The other areas 37, 38 of the floor, in which no spring elements 10 are effective open so that tar or the like drips down unhindered can.

Sämtliche in den Anmeldungsunterlagen offenbarten Merkmale werden als erfindungswesentlich beansprucht, soweit sie einzeln oder in Kombination gegenüber dem Stand der Technik neu sind.All features disclosed in the registration documents are claimed as essential to the invention, insofar as they are individually or new in combination with the prior art are.
