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.
