Abstract
Description
INDUSTRIEOFE&WAND INDUSTRIAL FURNACE & WALL
Die Erfindung geht aus von einer Industrieofenwand, bestehend aus einem äußeren tragenden Stahlblechmantel und einer drain innenseitig mit eingebetteten Ankern aus warmfestem Stahl befestigten feuerfesten Zustellung.The invention is based on an industrial furnace wall, consisting of an outer load-bearing sheet steel jacket and a drain on the inside with embedded Anchors made of heat-resistant steel attached refractory lining.
Bei bekannten Industrieofenwänden sind die Ankerrücken auf den Stahlblechmantel geschweißt. Das bedingt Justierungsschwierigkeiten bei der Montage, und gefährliche Spannungsbeanspruchungen im Betrieb, infolge des unterschiedlichen Temperaturganges und der unterschiedlichen Erwärmung der genannten Teile. Vorjällem aber erzeugen derartige Industrieöfen sehr großen Lärm beim Beschicken mit Behandlungsgut, etwa mit Brammen, oder beim Umwälzen des Behandlungsgutes, beispielsweise in einem Drehrohrofen. Die dabei entstehenden Stöße auf die Zustellung werden nämlich durch die eingebetteten Anker als Körperschall auf den Stahlblechmantel übertragen, der dabei wie eine große Lautsprechermembram wirkt.In known industrial furnace walls, the anchor backs are on the sheet steel jacket welded. This causes adjustment difficulties during assembly, and dangerous Stress loads during operation as a result of the different temperature changes and the different heating of the parts mentioned. But generate previous events Such industrial furnaces make a lot of noise when loading items to be treated, for example with slabs, or when the material to be treated is circulated, for example in a rotary kiln. The resulting impacts on the infeed are namely caused by the embedded Anchors are transmitted as structure-borne sound to the sheet steel jacket, which acts like a large Speaker cone works.
Um die Montage einer solchen Industrieofenwand bei Zulassung großer Herstellungstoleranzen schnell und einfach zu gestalten und gefährliche Temperaturspannungen sowie lästige Geräuschübertragung im Betrieb des Ofens zu vermeiden, wird erfindungsgemäß die kennzeichnende Merkmalskombination des Hauptanspruches vorgeschlagen. Die geteilte Buchse ist leicht einsetzbar, und ihr Mineralfaserflies dämpft die Übertragung von Körperschall sehr wirksam und überbrückt auch große Herstellungstoleranzen und unterschiedliche betriebliche Temperaturgänge, besonders wenn in Weiterbildung der Erfindung das Buchsenmaterial ein Nadelfilz ist, worin die MineralfaserzrückSederungsfähig sind, für sich bekannt aus DAS 22 32 785.For the installation of such an industrial furnace wall with approval large Manufacturing tolerances can be designed quickly and easily and dangerous Avoid temperature stresses and annoying noise transmission when the furnace is in operation, is according to the invention the characterizing combination of features of the main claim suggested. The split socket is easy to use and its mineral fiber fleece dampens the transmission of structure-borne noise very effectively and also bridges large manufacturing tolerances and different operational temperature curves, especially when in further training According to the invention, the bushing material is a needle felt, in which the mineral fiber is resilient are known per se from DAS 22 32 785.
Auch verhindert dieses Buchsenmaterial weitgehend eine Wärmeübertragung von den Ankern auf den Stehlblechmantel, so daß letzterer aus weniger warmfestem und entsprechend preiswerterem Material bestehen kann als die Anker.This bushing material also largely prevents heat transfer from the anchors to the steel sheet casing, so that the latter is made of less heat-resistant and can consist of cheaper material than the anchors.
Alle diese Vorteile werden in Weiterbildung der Erfindung noch vergrößert durch eine zusätzliche Schicht aus vorzugsweise vernadeltem Mineralfaserflies zwischen der Zustellung und dem Stahlblechmantel, dessen Haltebohrungen aussparend.All these advantages are further increased in a further development of the invention by an additional layer of preferably needled mineral fiber fleece between the infeed and the sheet steel jacket, leaving out the retaining bores.
Die Erfindung möge anhand des in der Figur im Teilschnitt schematisch dargestellten Ausführungsbeispiels veranschaulicht werden.The invention should be based on the in the figure in partial section schematically illustrated embodiment are illustrated.
Diese Industrieofenwand besteht aus einem äußeren tragenden Stahlblechmantel 4 und einer daran innenseitig mit eingebetteten Ankern 1 aus warmfestem Stahl besfestigten feuerfesten Zustellung mit einer verschleißfesten feuerseitigen Schicht 2 und einer wärmeisolierenden SchichtR'.This industrial furnace wall consists of an outer, load-bearing sheet steel jacket 4 and one fastened to it on the inside with embedded anchors 1 made of heat-resistant steel refractory lining with a wear-resistant fire-side layer 2 and one heat insulating layer R '.
Die Anker 1 sind auf den Kopf je einer Schraube 3 geschweißt, deren Schaft je eine mit Übermaß ausgeführte Haltebohrung 10 im Stahlblechmantel 4 durchsetzt, wobei koaxial zwischen dieser Bohrung und dem Schaft eine radial geteilte Buchse 5, 8 sitzt, die axial zwischen dem Schraubenkopf und einer Beilegscheibe 7 unter einer Mutter 6 außen auf dem Schraubenschaft verspannt ist. Die Buchse 5, 8 besteht aus vernadeltem Mineralfaserflies, vorzugsweise einer Mischung aus Al 203 und SiO2 -Fasern.The armature 1 are welded to the head of a screw 3, whose Shank each penetrated by an oversized holding hole 10 in the sheet steel jacket 4, being coaxial between this Bore and the shaft one radially split bushing 5, 8 sits axially between the screw head and a washer 7 is clamped under a nut 6 on the outside of the screw shaft. The socket 5, 8 consists of needled mineral fiber fleece, preferably a mixture of Al 203 and SiO2 fibers.
Die zusätzliche Mineralfaserschicht ist mit 9 bezeichnet.The additional mineral fiber layer is denoted by 9.
Sie hält allein durch die Spannkraft der Verschraubungen 3, 6.It is held in place solely by the clamping force of the screw connections 3, 6.
