Abstract
Description
Die Erfindung betrifft ein Ofensystem bestehend aus wenigstens zwei Öfen, wobei die Öfen jeweils einen Ofenraum mit wenigstens einer verschließbaren Zugangsöffnung umfassen.The The invention relates to a furnace system consisting of at least two furnaces, wherein the ovens each comprise a furnace chamber with at least one closable access opening.
Derartige
Ofensysteme sind in den unterschiedlichsten Ausführungen seit langem aus der Praxis
bekannt, vgl. z.B.
Während des Betriebes werden die einzelnen Öfen des Ofensystems zu unterschiedlichen Zeiten beladen und entladen, wobei jeweils Luft in den Ofenraum eintritt. Um während des Beladungsvorgangs die in anderen Öfen des Ofensystems ablaufende Wärmebehandlung nicht zu beeinträchtigen, ist es daher unerlässlich, die Ofenräume der einzelnen Öfen atmosphärisch strikt voneinander zu trennen. Dies erfolgt bei den aus dem Stand der Technik bekannten Systemen dadurch, dass jeder Ofen ein eigenes gasdicht verschließbares Gehäuse aufweist, welches nach erfolgter Ofenbeschickung mit Inertgas gefüllt werden kann.During the Operation will be the individual ovens loaded and unloaded at different times, wherein in each case air enters the furnace chamber. To during the Loading process occurring in other furnaces of the furnace system heat treatment not to affect is it is therefore essential the oven rooms the individual ovens atmospheric strictly separate from each other. This is done at the off The technology known systems in that each oven has its own gastight sealable casing which are filled with inert gas after the furnace has been charged can.
Ofensysteme dieser Bauart haben aufgrund der großen Gehäuseflächen jedoch den Nachteil, im Betrieb hohe Wärmeverluste zu erleiden. Diese können nur durch eine aufwendige Isolation der Gehäusewand gemindert werden, was wiederum mit hohen Investitionskosten verbunden ist. Ferner benötigen Ofensysteme dieser Art stets eine große Stellfläche.furnace systems This type, however, have the disadvantage in operation due to the large housing surfaces high heat losses to suffer. these can only be mitigated by a complex insulation of the housing wall, which again associated with high investment costs. Further, furnace systems require this kind always a big one Footprint.
Es ist daher Aufgabe der Erfindung, ein Ofensystem der eingangs genannten Art anzugeben, welches sich gegenüber den aus dem Stand der Technik bekannten Systemen durch verringerte Anlagenkosten auszeichnet.It is therefore an object of the invention, a furnace system of the aforementioned Specify type, which is compared to those of the prior art known systems characterized by reduced system costs.
Die Aufgabe wird erfindungsgemäß mit einem Ofensystem mit den Merkmalen des Kennzeichnungsteils des Patentanspruches 1 dadurch gelöst, dass die Öfen in einem gemeinsamen Gehäuse angeordnet sind, wobei jeweils benachbart angeordnete Ofenräume durch eine gasdichte Zwischenwand voneinander getrennt sind und dass die Zwischenwand Kompensatorfaltungen aufweist.The Task is according to the invention with a Furnace system with the features of the characterizing part of claim 1 solved by that the ovens in a common housing are arranged, each adjacent furnace chambers arranged through a gas-tight partition are separated from each other and that the Intermediate wall Kompensatorfaltungen.
Durch die Gasdichtigkeit der Zwischenwand können die einzelnen Öfen des Ofensystems wie bei den aus dem Stand der Technik bekannten Systemen voneinander unabhängig betrieben, insbesondere also beschickt und entladen werden.By the gas tightness of the intermediate wall, the individual stoves of the Furnace system as in the systems known from the prior art from each other independently operated, in particular so be charged and discharged.
Der besondere Vorteil des erfindungsgemäßen Ofensystems liegt darin, dass durch Integration der einzelnen Öfen in ein gemeinsames Gehäuse bei jeweils benachbart angeordneten Öfen die beiden einander zugewandten Außenflächen durch eine gemeinsame Zwischenwand ersetzt ist. Da diese im isolierten Gesamtgehäuse angeordnet ist, entfallen hier somit aufwendige Isolierungsmaßnahmen. Dabei werden desto größere Kostenvorteile erzielt, je mehr Öfen in ein gemeinsames Gehäuse in der erfindungsgemäßen Weise integriert werden. Aufgrund der im Vergleich zu konventionellen Ofensystemen mit gesonderten Gehäusen erheblich reduzierten Außenfläche, sind auch die Wärmeverluste im Betrieb reduziert, was zu einem besonders wirtschaftlichen Betrieb des Ofensystems beiträgt. Schließlich wird die durch das erfindungsgemäße Ofensystem beanspruchte Stellfläche optimal genutzt.Of the particular advantage of the furnace system according to the invention lies in that by integrating the individual ovens into a common housing at each adjacent stoves the two outer surfaces facing each other by a common Intermediate wall is replaced. Since these are arranged in the isolated overall housing is, thus eliminating costly isolation measures. In doing so, the greater the cost advantages scored, the more stoves in a common housing in the manner according to the invention to get integrated. Because of compared to conventional Furnace systems with separate housings considerably reduced outer surface, are also the heat losses reduced in operation, resulting in a particularly economical operation contributes to the furnace system. After all is the by the furnace system according to the invention claimed footprint optimally used.
Nach einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die Zwischenwand aus einem austhenitischen Stahl hergestellt ist. Diese Stähle zeichnen sich durch eine besonders hohe Temperaturbeständigkeit und Langlebigkeit aus und sind somit für einen Dauereinsatz in einem Ofen gut geeignet. Die üblichen Kompensatormaterialien wie zum Beispiel Gewebe mit Teflonbeschichtung o.ä. können aufgrund der hohen beidseitigen thermischen Belastung (max. 550°C) nicht verwendet werden.To an advantageous embodiment of the invention is provided that the intermediate wall is made of austenitic steel is. These steels are characterized by a particularly high temperature resistance and longevity and are thus for continuous use in one Oven well suited. The usual Compensator materials such as tissue with Teflon coating etc. can due the high double-sided thermal load (max 550 ° C) is not be used.
Dadurch, dass die Zwischenwand erfindungsgemäß Kompensatorfaltungen aufweist ist sichergestellt, dass die im Betrieb erfolgende thermische Ausdehnung der Zwischenwand derart kompensiert werden kann, dass es nicht zu einer Veränderung ihrer Außenabmessungen kommt, wodurch die gasdichte Verbindung zwischen der Zwischenwand und der kalten Gehäusewand zerstört werden würde.Thereby, that the intermediate wall according to the invention has Kompensatorfaltungen it is ensured that the thermal expansion occurring during operation the partition can be compensated so that it does not a change their external dimensions comes, creating the gas-tight connection between the intermediate wall and the cold housing wall destroyed would become.
Die Kompensatorfaltungen der Zwischenwand, die als V-Nuten ausgebildet sein können, sind dabei beispielsweise kreuzweise zueinander unter Ausbildung von Kreuzungsöffnungen angeordnet, wobei die Kreuzungsöffnungen durch flexible Dichtungselemente abgedichtet sind.The Compensator folds of the intermediate wall, which are formed as V-grooves could be, are, for example, crosswise to each other under training from intersection openings arranged, with the crossing openings sealed by flexible sealing elements.
