Description
Die vorliegende Erfindung betrifft eine Wandkonstruktion zur Verwendung in einem Ofen zur Kalzinierung von Kohlenstoffblöcken, wie im Oberbegriff von Anspruch 1 erwähnt. Solch eine Wandkonstruktion ist aus WO 92/227780 A1 bekannt.The The present invention relates to a wall construction for use in an oven for the calcination of carbon blocks, as in the preamble of Claim 1 mentioned. Such a wall construction is known from WO 92/227780 A1.
Öfen zur Kalzinierung von Kohlenstoffblöcken, welche bei der Herstellung von Aluminium in Übereinstimmung mit dem Hall-Hérault-Verfahren verwendet werden sollen, können mit mehreren Kammern ausgestaltet werden, die in zwei parallelen Reihen angeordnet sind. Derartige Öfen weisen einen Verbrennungszyklus auf, welcher im Verhältnis zu den Kammern in dem Maße bewegt wird, wie das Kohlenstoffmaterial kalziniert wird. Die Kammern sind wechselseitig und aufeinander folgend durch Kanäle verbunden, welche heißes Verbrennungsgas oder Rauchgas durch die Ofenkonstruktion führen. Jede Kammer kann durch Abzugswände oder Kassettenwände in mehrere kleinere Gruben unterteilt werden. Diese Abzugswände sind mit mehreren Rauchgaskanälen ausgestattet, durch welche heißes Gas geführt wird, damit Wärme auf wirkungsvolle Weise auf die Gegenstände übertragen wird, welche in den Kammern angeordnet sind, damit der Kalzinierungsvorgang möglichst homogen abläuft.Ovens for Calcination of carbon blocks, which is used in the production of aluminum in accordance with the Hall-Hérault process to be able to be designed with several chambers, in two parallel rows are arranged. Such ovens have a combustion cycle which is proportional to the chambers to the extent is moved as the carbon material is calcined. The chambers are mutually and sequentially connected by channels, which hot combustion gas or Run flue gas through the furnace construction. Each chamber can through deduction walls or cassette walls divided into several smaller pits. These deduction walls are with several flue gas channels equipped by which hot gas guided will, with it heat is effectively transferred to the objects which are in the Chambers are arranged so that the calcination process as possible runs homogeneously.
Ein Problem, das bei diesen Öfen auftritt, bei welchen die Abzugswände sich über mehrere Meter sowohl vertikal als auch horizontal erstrecken, besteht darin, dass diese Wände im Verlauf der Zeit aufgrund von Erhitzung-/Abkühlungszyklen mit großen Temperaturunterschieden ihre parallele Ausrichtung verlieren. In den schlimmsten Fällen kann es durch Wölbung und Rissbildung problematisch werden, den Ofen auf zufrieden stellende Weise zu betreiben. Dies passiert aufgrund von Leckagen und Abbrennen oder aufgrund von Problemen beim Einführen/Entfernen von Gegenständen, als Folge von großen geometrischen Abweichungen in den Gruben.One Problem with these ovens occurs in which the deduction walls over several meters both vertically as well as extending horizontally, is that these walls in the course time due to heating / cooling cycles with large temperature differences lose their parallel alignment. In the worst cases can it by vaulting and cracking become problematic, the oven to satisfactory Way to operate. This happens due to leaks and burning off or due to insertion / removal problems of objects, as a result of big ones geometric deviations in the pits.
Die Aufgabe der vorliegenden Erfindung besteht darin, eine Wandkonstruktion zur Verfügung zu stellen, bei welcher das Ausdehnen oder das Zusammenziehen der Wandkonstruktion in ihrer länglichen Ausdehnung als eine Folge von thermalen Zyklen ausgeglichen wird, indem Ziegelsteine wechselseitig einrasten, wobei eine Wandkonstruktionen zur Verfügung gestellt wird, die im Verlauf von wiederholten Temperaturzyklen sehr stabil bleibt und mit der die Kosten, welche mit der Instandsetzung von Mauerwerk verbunden sind, und mögliche Betriebsunterbrechungen des Ofens infolgedessen beträchtlich reduziert werden können.The Object of the present invention is a wall construction to disposal to ask, in which the expansion or contraction of the Wall construction in its elongated extension as a result of thermal cycles is compensated by bricks Snap mutually, using a wall structures provided which becomes very stable in the course of repeated temperature cycles and with the costs associated with the repair of Masonry are connected, and possible Operating interruptions of the furnace as a result considerably can be reduced.
Diese Aufgabe wird mit einer Wandkonstruktion, wie sie in Anspruch 1 definiert ist, erfüllt.These Task is with a wall construction, as defined in claim 1 is satisfied.
Spezifische Ausführungsformen der Wandkonstruktion nach der vorliegenden Erfindung sind Gegenstand der Ansprüche 2 bis 7.specific embodiments the wall construction according to the present invention are the subject the claims 2 to 7.
Nachfolgend wird die vorliegende Erfindung im Detail anhand von Beispielen und Zeichnungen beschrieben, wobei:following the present invention will be described in detail by way of examples and Drawings are described, wherein:

Die
Figur zeigt, dass das Muster für
die Ziegelsteinschicht der Trennwand
Obwohl die Beispiele Trennwände mit Rauchgaskanälen zeigen, können gleichwertige Vorteile und Prinzipien der vorliegenden Erfindung genauso gut für Wandkonstruktionen ausgenutzt werden, durch welche keine Kanäle verlaufen, bei denen die Konstruktion auf andere Art enormen Wärmebelastungen unterliegt. Dies kann beispielsweise der Fall bei Wandkonstruktionen sein, die innerhalb einer Ofenkammer installiert sind, um die Kammer zu unterteilen.Even though the examples partitions with flue gas channels be able to show equivalent advantages and principles of the present invention as well for Wall constructions are exploited through which no channels pass, where the construction in other ways enormous heat loads subject. This can be the case with wall constructions, for example be installed inside a furnace chamber to the chamber to divide.
Bei den gezeigten Ausführungsformen sind die Kontaktelemente dergestalt ausgestaltet, dass Vorsprünge an der Oberseite der Ziegelsteine angeordnet sind, wohingegen Vertiefungen an der Unterseite der Ziegelsteine angeordnet sind. Allerdings würde es genauso gut im Rahmen der vorliegenden Erfindung liegen, wenn die Vorsprünge an dem Boden und die Vertiefungen an der Oberseite angeordnet wären oder wenn möglicherweise eine Kombination von diesen beiden verwendet würde.at the embodiments shown the contact elements are designed such that projections on the Top of the bricks are arranged, whereas depressions are arranged at the bottom of the bricks. However, it would be the same are well within the scope of the present invention, when the projections on the Floor and the recesses were arranged at the top or if possible a combination of these two would be used.
In Übereinstimmung mit der vorliegenden Erfindung können die Bewegungen, welche in der Wandkonstruktion auftreten, überwiegend zumindest an einem Ende absorbiert werden, welches an weiterem Mauerwerk in einem Ofen befestigt sein kann. Eine gewisse relative Bewegung muss außerdem zwischen der Wandkonstruktion und ihrer darunter liegenden Konstruktion ermöglicht werden, beispielsweise gegenüber einer festen Bodenkonstruktion.In accordance with the present invention the movements that occur in the wall construction, predominantly be absorbed at least at one end, which on further masonry can be mounted in an oven. A certain relative movement must also between the wall construction and its underlying construction are made possible for example, opposite a solid floor construction.
