Description
Abdichtungseinrichtung an einem Durchlauf-Glühofen. Gegenstand vorliegender .Erfindung ist eine Abdichtungseinrichtung an einem Durch- lauf-C".lühofen mir Abdichtung des Raumes über den Plattformen für das Glühgut gegen über dem Raum unter diesen Plattformen. Es ist bekannt, solche Abdichtungen mittels Sand tassen vorzunehmen. Aus konstruktiven Grün den müssen solche Sandtassen verhältnismässig tief unter die Plattformebene gelegt werden.
Dadurch werden sowohl die Seitenteile der Plattform und der Wagengestelle wie auch ein zusätzlicher Teil des Ofenmauerwerkes den heissen Ofengasen ausgesetzt. In den lang- gestreckt.en Räumen zwischen Sandtasse und Plattformebene ist. ein unerwünschtes Abflie ssen der Wärme aus Zonen höherer Tempera tur in Zonen niedrigerer Temperatur festzu stellen. Es ist ferner bekannt, röhrenförmige Abdichtungskörper über die Spalten von Glühwagen zu legen.
Für sich allein. verwen det, genügen diese Röhren bei hohen Tempe- raturen nicht, um eine Gasströmung ganz zu verhindern. Die vorliegende Erfindung unterscheidet sich von bekannten Abdichtun gen darin, da13 die Ränder der Plattformen gegen aussen abwärtsgeneig-te Flächen auf weisen und über den Spalten zur Abdichtung Röhren aus feuerfestem Material angeordnet sind sowie vom Rauni über den Plattformen weiter entfernt eine doppelte Abdichtung durch Sandtassen vorgesehen ist.
Die Zeichnungen zeigen ein Ausführungs- beispiel der Erfindung; es stellt dar: Fig.l eine Darstellung einer doppelten Abdichtung gegen die Ofenwand und Fig.2 eine Darstellung einer doppelten Abdichtung zwischen zwei Glühwagen.
In Fig.l ist. ein Stück der Ofenmauer 1 eines Durchlauf-Glühofens im Schnitt ge zeichnet. Der nur andeutungsweise dargestellte Glühwagen 2 mit seiner Plattform 3 ist auf seiner obern Seite mit einer nach aussen ab- wärtsgeneig-ten Fläche 4 versehen, in welche Körper 5 aus feuerfestem, keramischem Mate rial aneinandergereiht werden.
Die Fig. 1 zeigt weiter ein am Gestell des Glühwagens 2 befestigtes Blech 6, welches in eine Sand tasse 7 eintailcht. Durch diese Anordnung ent steht. eine doppelte Abdichtung mit verstärk ter Wirkung, indem zwischen dem Raum 8 über der Plattform 3 und dem Raum 9 unter der Plattform 3 ein Zwischenraum 10 gebildet wird. Dass Wärmegefälle zwischen den Räu men 8 und 9 verteilt sich auf die erste Ab dichtung durch die Körper 5, den Zwischen raum 10 und die Abdichtung durch die Sand- tassen 6, 7.
Fig.2 zeigt eine doppelte Abdichtung an den quer zur Ofenlängsachse verlaufenden Spalten zwischen den einzelnen nur andeu tungsweise dargestellten Glühwagen 2. Die Flächen 4 für die Körper 5 sind dieselben wie bei Fig.1. Zusätzlich zu dieser obern Ab dichtung ist am Gestell des Glühwagens 2 eine Sandtasse, bestehend aus einer Nase 11 und der Tasse 12 angeordnet.
Die @Tirkung der doppelten Abdichtung gemäss Fig.2 ist die selbe wie die Wirkung der Abdichtung von Fig.1. In Fig. 2 ist ein Stab 13 eingezeichnet, welcher durch die röhrenförmigen Körper 5 hindurchgesteckt ist. Durch eine solche An ordnung kann der Spalt 14 zwischen zwei Glühwagen 2 mit einer einzigen Operation ab gedichtet werden, wodurch Zeit und Mühe erspart wird.
Die Wirkung der doppelten Abdichtung von röhrenförmigen Körpern und Sandtassen ist vergleichbar mit der abdichtenden Wir kung bei sogenannten Vorfenstern oder Win terfenstern an Häusern. Die zwischen den bei den Dichtungen stehende Luftschicht unter stützt die Abdichtung wirksam. Durch Auswahl geeigneter Materialien kann neben der abdichtenden noch eine wärmeisolierende Wirkung erzielt werden.
Sealing device on a continuous annealing furnace. The subject of the present invention is a sealing device on a continuous C "annealing furnace with sealing of the space above the platforms for the annealing material from the space below these platforms. It is known to make such seals by means of sand cups. For structural reasons such sand cups must be placed relatively deep under the platform level.
As a result, both the side parts of the platform and the carriage frames as well as an additional part of the furnace masonry are exposed to the hot furnace gases. In the elongated spaces between the sand cup and platform level is. an undesirable flow of heat from zones of higher temperature to zones of lower temperature can be determined. It is also known to place tubular sealing bodies over the crevices of annealing cars.
To yourself. are used, these tubes are not sufficient at high temperatures to completely prevent gas flow. The present invention differs from known seals in that the edges of the platforms have surfaces sloping downwards towards the outside and pipes made of refractory material are arranged above the gaps for sealing, and a double seal is provided by sand cups further away from the space above the platforms is.
The drawings show an exemplary embodiment of the invention; It shows: Fig.l a representation of a double seal against the furnace wall and Fig.2 a representation of a double seal between two annealing cars.
In Fig.l is. a piece of the furnace wall 1 of a continuous annealing furnace in section ge draws. The annealing trolley 2 with its platform 3, shown only hinted at, is provided on its upper side with an outwardly downward-sloping surface 4 in which bodies 5 made of refractory, ceramic material are lined up.
Fig. 1 also shows a sheet metal 6 attached to the frame of the annealing car 2, which cup 7 eintailcht in a sand. This arrangement ent stands. a double seal with a reinforced effect by forming a space 10 between the space 8 above the platform 3 and the space 9 below the platform 3. The heat gradient between the spaces 8 and 9 is distributed over the first seal through the body 5, the intermediate space 10 and the seal through the sand cups 6, 7.
FIG. 2 shows a double seal on the gaps running transversely to the longitudinal axis of the furnace between the individual annealing cars 2, which are only hinted at. The surfaces 4 for the bodies 5 are the same as in FIG. In addition to this upper seal from above, a sand cup consisting of a nose 11 and the cup 12 is arranged on the frame of the glow car 2.
The effect of the double seal according to Fig.2 is the same as the effect of the seal from Fig.1. In FIG. 2, a rod 13 is shown which is pushed through the tubular body 5. By such an arrangement, the gap 14 between two annealing cars 2 can be sealed with a single operation, which saves time and effort.
The effect of the double sealing of tubular bodies and sand cups is comparable to the sealing effect on so-called front windows or winter windows on houses. The layer of air between the gaskets supports the seal effectively. By selecting suitable materials, a heat-insulating effect can be achieved in addition to the sealing effect.
