Abstract
Description
Die Erfindung bezieht sich auf eine Wärme- und Luftdichtung an den einander zugewandten Stoßfugen von Ofenwagen z. B. Tunnel öfen oder Herdwagenöfen.The invention relates to a heat and air seal on the mutually facing butt joints of kiln cars z. B. Tunnels ovens or bogie hearth ovens.
Nach dem Stand der Technik erfolgt die Abdichtung solcher Brennwagen untereinander an ihren Stoßstellen mittels Dicht schnüren. Diese werden in Stahlprofile eingelegt, welche stirn seitig an den Stahlrahmen der Brennwagen angebracht sind.According to the prior art, such is sealed Brennwagen with each other at their joints by means of sealing lace. These are inserted into steel profiles, which face are attached to the steel frame of the kiln car.
Verbesserungen wurden erzielt durch Anordnung von Federblechen oder z. B. eine Keilspaltdichtung nach DBGM 84 31 174.6. Der verbleibende Nachteil solcher Dichtungssysteme besteht im Eindringen von sehr heißen Gasen im darüberliegenden Spalt zwischen den Wagenaufmauerungen aus dem Ofenraum, besonders wenn derselbe mit Überdruck betrieben werden soll. Es wurden daher schon Wagenchassis zur Verzunderung oder Verbiegung ge bracht. Außerdem entsteht eine große Erwärmung der Brennwagen unterseiten, was zur Überhitzung von Brennwagenradlagerungen und Schmiermittel führt.Improvements have been achieved by arranging spring plates or z. B. a wedge gap seal according to DBGM 84 31 174.6. The remaining disadvantage of such sealing systems is Penetration of very hot gases in the gap above between the car walls from the furnace room, especially if the same is to be operated with overpressure. There were therefore already ge chassis for scaling or bending ge brings. In addition, the kiln cars become very hot underside, which leads to overheating of Brennwagen wheel bearings and lubricants.
Gelegentlich wird auch versucht, an die Stirnseiten der Aufmauerungen ein- oder beidseitig Streifen von Keramik fasermatten anzukleben, was sich aber nicht als haltbar erweist.Occasionally, attempts are also made to face the front of the Masonry strips of ceramic on one or both sides stick on fiber mats, but this is not durable turns out.
Aufgabe der Erfindung ist daher, eine Brennwagendichtung für die stirnseitige, möglicherweise auch für die seitliche Brennwagenabdichtung gegenüber der Ofenwand anzugeben, welche vorstehende Nachteile vermeidet. Daher soll diese leicht her zustellen und ebenso leicht bei Verschleiß auszuwechseln sein.The object of the invention is therefore a gasket for the front, possibly also for the side The kiln car seal opposite the furnace wall must be specified avoids the above disadvantages. Therefore, this should be easy deliver and replace just as easily when worn be.
Gemäß der Erfindung wird vorgeschlagen, an einer der Brenn wagenstirnseiten (1) eine keramische Fasermatte (2) oder ähn liches Material (gem. Fig. 1) über metallische Ständer (3), welche am Brennwagenchassis aufgestützt sind, umzustülpen, so daß ihre beiden Lappen (4) nach unten hängen.According to the invention it is proposed to turn over on one of the end faces of the kiln ( 1 ) a ceramic fiber mat ( 2 ) or similar material (according to FIG. 1) via metallic stands ( 3 ) which are supported on the kiln chassis so that their two Hang the rag ( 4 ) down.
Die Ständer (3) sind daher entsprechend dem stirnseitigen Labyrinth der Wagenaufmauerung gebogen oder können statt im Chassis auch in den Stirnseiten der Aufmauerung verankert werden. Die Ständer (3) können mehrteilig über die Brennwagen breite hergestellt und mit oberen Querleisten (5) versehen sein, um die welche die Fasermatte umgestülpt wird. Die Stulp stelle liegt in jedem Fall im Höhenbereich des feuerfesten Wagenbelages oder auch noch über diesem. Dann muß allerdings das Material der Querleisten sehr hitzebeständig ausgeführt werden.The uprights ( 3 ) are therefore bent in accordance with the labyrinth on the front of the car wall or can also be anchored in the front of the wall instead of in the chassis. The stand ( 3 ) can be made in several parts across the kiln width and can be provided with upper cross strips ( 5 ) around which the fiber mat is turned inside out. The faceplate is in any case in the height range of the refractory covering or even above this. Then, however, the material of the cross strips must be made very heat-resistant.
Nach Fig. 2 ist eine solche Ausführungsform dargestellt, wobei die Stulpstelle ihre ausgewulstete Form besonders gut beibehält, da sie nicht so stark gedrückt wird wie zwischen der Feuerfestaufmauerung gelegen.Such an embodiment is shown in FIG. 2, the forend maintaining its bulged shape particularly well, since it is not pressed as strongly as is located between the refractory brickwork.
In jedem Fall ist das Eindringen von heißen Ofengasen in den Spalt zwischen den einzelnen Brennwagen unterbunden, so daß dadurch hervorgerufene Wärmeverluste und Schädigungen am Brennwagen unterbunden werden.In any case, the penetration of hot furnace gases into the Gap between the individual kilns prevented, so that heat losses and damage to the Brennwagen be prevented.
