Description

Die Erfindung betrifft ein Verfahren zum Ausbessern von Wänden eines Industrieofens, insbesondere der Heizwände einer Verkokungsbatterie nach dem Oberbegriff des Hauptanspruches.The invention relates to a method for repairing walls of an industrial furnace, in particular the heating walls of a coking battery according to the preamble of the main claim.

Durch die DE-A-3425851 ist ein Verfahren zur teilweisen oder vollständigen Erneuerung von Heizwänden einer Verkokungsofenbatterie bekannt. Hierbei werden benachbarte Mauerwerksteile im wesentlichen auf Betriebstemperatur gehalten; das Aufmauern des neu zu erstellenden Mauerwerks erfolgt in der Weise, daß die Binderwände entsprechend den Warmmaßen angeordnet werden und daß die erforderlichen Dehnfugen der Läuferwände im Bereich der Binderköpfe vorgesehen und mit einem feuerfesten Fasermaterial ausgefüllt werden.DE-A-3425851 discloses a method for the partial or complete renewal of heating walls of a coking furnace battery. Here, adjacent masonry parts are kept essentially at operating temperature; the masonry to be newly built is done in such a way that the truss walls are arranged according to the warm dimensions and that the necessary expansion joints of the runner walls are provided in the area of the binder heads and filled with a refractory fiber material.

Diesen bekannten Verfahren gegenüber besteht die Aufgabe der Erfindung darin, die Ausbesserung so zu gestalten, daß die Ofenwand über den gesamten ausgebesserten Wandbereich wieder völlig gasdicht wird, die Arbeiten hierzu problemlos, die Vorbereitungen einfach und die anzuwendenden Mittel preisgünstig sind.Compared to these known methods, the object of the invention is to design the repair in such a way that the furnace wall becomes completely gas-tight again over the entire repaired wall area, the work for this is easy, the preparations are simple and the means to be used are inexpensive.

Zur Lösung dieser Aufgabe sieht die Erfindung die Merkmale der kennzeichnenden Teils des Hauptanspruches vor. Die Merkmale der Unteransprüche dienen der Verbesserung und Weiterentwicklung der Merkmale des Hauptanspruches.To achieve this object, the invention provides the features of the characterizing part of the main claim. The features of the subclaims serve to improve and further develop the features of the main claim.

Der Vorteil des erfindungsgemäßen Verfahrens ist darin zu sehen, daß die Dehnung des Mauerwerks bei seiner Erwärmung nur in einem Maße zu berücksichtigen ist, daß lediglich ein Zwischenraum zwischen dem alten und dem neuen Mauerwerk zu bilden ist, der etwas größer als die Dehnung des erwärmten Mauerwerks ist. Es kommt somit nicht mehr auf eine genaue Berechnung und Ausführung einer Fuge zwischen dem alten und dem neuen Mauerwerk, die dem Warmmaß oder der Dehnung entspricht an bzw. darauf an, daß in dem Zwischenraum zwischen dem alten und dem neuen Mauerwerk keramisches Fasermaterial eingebracht wird, das mögliche noch verbliebene Fugen zwischen dem erwärmten alten und dem neuen Mauerwerk schließt. - Die Erfingung bietet die Möglichkeit, daß das gasdichte Abschließen der Läuferwand, in Sonderheit durch keramisches Schweißen, das z.B. in der DE-A-2053420 beschrieben ist, unmittelbar nach dem Aufheizen der benachbarten Wandabschnitte, d. h. durch Verschweißen des Zwischenraumes zwischen dem alten und dem neuen Mauerwerk erfolgen kann. - Das erfindungsgemäße Verfahren bietet die Möglichkeit, auf eine exakte und geradlinige oder geradflächige Begrenzung der Randkante zumindestens des alten Mauerwerks verzichten zu können. Diese Arbeiten können mit Hammer und Meißel ausgeführt werden; ggf. kann nach dem Erwärmen die unregelmäßig bearbeitete Randkante scharriert werden. - Es zeigt sich ferner der Vorteil, daß für das neue Mauerwerk typunabhängige Steine verwendet werden können, die entweder stets verfügbar oder kurzzeitig beschaffbar sind.The advantage of the method according to the invention can be seen in the fact that the expansion of the masonry when it is heated is to be taken into account only to an extent that only an intermediate space between the old and the new masonry is to be formed, which is somewhat larger than the expansion of the heated masonry is. This means that there is no longer any precise calculation and execution of a joint between the old and the new masonry that corresponds to the warm dimension or the expansion or to the fact that in the space between the old and the new masonry ceramic fiber material is introduced, which closes any remaining joints between the heated old and new masonry. - The invention offers the possibility that the gas-tight sealing of the rotor wall, in particular by ceramic welding, which is described, for example, in DE-A-2053420, immediately after the heating of the adjacent wall sections, ie by welding the space between the old and the new masonry can be done. - The method according to the invention offers the possibility of being able to dispense with an exact and rectilinear or rectilinear limitation of the edge at least of the old masonry. This work can be done with a hammer and chisel; if necessary, the irregularly machined edge can be scratched after heating. - There is also the advantage that type-independent stones can be used for the new masonry, which are either always available or can be procured for a short time.

Auf der beigefügten Zeichnung sind verschiedene Arbeitsweisen nach dem erfindungsgemäßen Verfahren dargestellt und zwar zeigt.

Fig. 1 bis 4
die beiden Läuferwände einer Verkokungsbatterie sowie das Einsetzen des neuen Mauerwerks in einem Abschnitt der Wände,
Fig. 5 und 6
zeigen ein weitere Möglichkeit der Anordnung und Ausbildung des neuen, in die Läuferwände einzusetzenden Mauerwerks und
Fig. 7 und 8
die Möglichkeit, den Zwischenraum zwischen dem alten und dem neuen Mauerwerk im inneren Wandabschnitt mit keramischem Fasermaterial zu verfüllen, um das spätere Ausfüllen der Zwischenräume durch keramische Schweißmasse zu erleichtern. Die im inneren Wandabschnitt eingestopfte keramische Fasermasse verhindert den Durchtritt von Schweißmasse durch die Zwischenräume in die Heizzüge.
On the accompanying drawing, different ways of working according to the inventive method are shown and that shows.
1 to 4
the two runner walls of a coking battery and the insertion of the new masonry in a section of the walls,
5 and 6
show another way of arranging and training the new masonry and to be inserted into the runner walls
7 and 8
the possibility of filling the space between the old and new masonry in the inner wall section with ceramic fiber material in order to make it easier for the spaces to be filled later with ceramic welding compound. The ceramic fiber mass stuffed in the inner wall section prevents sweat mass from passing through the gaps in the heating cables.

Mit dem erfindungsgemäßen Verfahren gilt, es, die beiden parallelen Läuferwände 1, 2 einer Verkokungsbatterie auszubessern. Zwischen den beiden Wänden erstrecken sich die Binderwände 3, zwischen denen einerseits und den Läuferwänden andererseits die Heizzüge 4 gebildet sind. Der Bereich 5 zwischen den alten Mauerwerksabschnitten 6 und 7 ist in üblicher Weise von dem schadhaften Mauerwerk befreit worden, so daß der Bereich 5 seitlich von den Randkanten 8, 9 der alten Mauerwerksabschnitte 6, 7 begrenzt wird. Diese Mauerwerksabschnitte erhalten gegenüber der Längsmittelebene E der Läuferwände 1, 2 eine Neigung mit einem Winkel α derart, daß der Abstand der äußeren Kanten 10 des Bereiches 5 voneinander größer als der Abstand der inneren Kanten 11 ist.With the method according to the invention it is important to repair the two parallel rotor walls 1, 2 of a coking battery. The truss walls 3 extend between the two walls, between which the heating cables 4 are formed on the one hand and the runner walls on the other. The area 5 between the old masonry sections 6 and 7 has been freed from the defective masonry in the usual way, so that the area 5 laterally from the Edge edges 8, 9 of the old masonry sections 6, 7 is limited. These masonry sections are inclined relative to the longitudinal center plane E of the rotor walls 1, 2 at an angle α such that the distance between the outer edges 10 of the area 5 is greater than the distance between the inner edges 11.

Das Erstellen der Randkanten 8, 9 erfolgt in einfacher Weise durch Hammer und/oder Meißel, ohne eine bestimmte Konfiguration des Bereiches 5 zu erlangen.The edge edges 8, 9 are created in a simple manner by means of a hammer and / or chisel, without attaining a specific configuration of the area 5.

In dem Bereich 5 wird ein neues Mauerwerk 12 aufgemauert, das, wie bei der Ausführungsform nach Fig. 3 und 4 widergegeben ist, eine ebenfalls gegenüber der Ebene E der Läuferwände 6 und 7 gerichtete Neigung besitzen kann und zwar derart, daß zwischen den Randkanten 8, 9 der alten Mauerwerksabschnitte 6, 7 und 13, 14 des neuen Mauerwerks 12 ein V- oder keilförmiger Zwischenraum 15, 16 gebildet wird. Hierbei haben die Zwischenräume 15, 16 eine mittlere Breite a bzw. b, die etwas größer ist, als die beim Erwärmen der Mauerwerksteile zu erwartende Dehnung derselben ist. Der mittlere Abstand der Randkanten 8, 9 und 13, 14 voneinander beträgt vorzugsweise ca. 50 bis 100 Millimeter.In the area 5, a new masonry 12 is bricked up, which, as shown in the embodiment according to FIGS. 3 and 4, may also have an inclination directed towards the plane E of the runner walls 6 and 7, in such a way that between the edge edges 8 , 9 of the old masonry sections 6, 7 and 13, 14 of the new masonry 12 a V or wedge-shaped space 15, 16 is formed. Here, the spaces 15, 16 have an average width a and b, respectively, which is somewhat larger than the expansion of the masonry parts to be expected when they are heated. The average distance between the edge edges 8, 9 and 13, 14 from one another is preferably approximately 50 to 100 millimeters.

Diese bis hier durchgeführten Arbeiten sind in kaltem Zustand der neuen Mauerwerksteile 12 ausgeführt worden.-Im Anschluß hieran werden die V-förmigen Zwischenräume 15, 16 durch Verfahren keramisches Schweißen, vorzugsweise unter Anwendung einer Masse nach dem DE-Patent 20 53 420, gasdicht verschlossen, nachdem die Wände oder die Wandabschnitte 6, 7 und 12 ihre größte Ausdehnung nach einer bestimmten Erwärmungszeit erlangt haben.This work carried out up to here has been carried out in the cold state of the new masonry parts 12. Subsequently, the V-shaped spaces 15, 16 are sealed gas-tight by ceramic welding methods, preferably using a composition according to DE patent 20 53 420 after the walls or the wall sections 6, 7 and 12 have reached their greatest expansion after a certain heating time.

In Fig. 5 und 6 ist dargestellt, daß das neue Mauerwerk 12 mit ebenflächigen Stirnkanten ausgeführt sein kann, wobei die einzelnen Lagen des neuen Mauerwerks 12 stufenartig gestaltet sein können. So können senkrechte Stufen 22, 23, 24 gebildet sein, wobei die benachbarte Randkante 8 des alten Mauerwerksabschnitte 6 einen senkrechten oder annähernd senkrechten Verlauf zeigt. - Das Mauerwerk 12 kann jedoch gegenüber dem alten Mauerwerksabschnitt 7, wie in Fig. 5 und 6 dargestellt, nicht nur vor- und zurückspringende Abschnitte 25, 26, 27 aufweisen, sondern auch treppenartig angeordnete Abschnitte 28, 29, 30, denen rückspringende Abschnitte 31, 32, 33 der Randkante 9 entsprechen.5 and 6 show that the new masonry 12 can be designed with flat end edges, the individual layers of the new masonry 12 can be designed in steps. In this way, vertical steps 22, 23, 24 can be formed, the adjacent edge 8 of the old masonry sections 6 showing a vertical or approximately vertical course. - The masonry 12, however, compared to the old masonry section 7, as shown in FIGS. 5 and 6, not only have protruding and recessed sections 25, 26, 27, but also sections 28, 29, 30 arranged like steps, the recessed sections 31 , 32, 33 correspond to the edge 9.

Als Mauerwerksöffnung sind auch Öffnungen am Anfang und Ende einer Läuferwand zu verstehen. Hier wird am Wandanfang oder -ende der Eckbereich aus schadhaftem, altem Mauerwerk abgerissen und durch neues Mauerwerk unter Bildung eines Zwischenraumes, wie er vorstehend beschrieben ist, ersetzt, wonach das alte und das neue Mauerwerk, wie ausgeführt, behandelt und der Zwischenraum geschlossen wird.Masonry openings are also openings at the beginning and end of a runner wall. Here, at the beginning or end of the wall, the corner area is made of damaged, old masonry demolished and replaced by new masonry to form a space as described above, after which the old and new masonry are treated as described and the space is closed.

Ein Vorteil des Verfahrens liegt darin, daß die für das Aufmauern des neuen Mauerwerksteils zur Verwendung kommenden Steine unabhängig von den Steinprofilen des alten Mauerwerks gewählt werden können. Da die Zwischenräume zwischen altem und neuem Mauerwerk unregelmäßig sein können, spielt die Lage der Stoß-und Lagerfugen des neuen Mauerwerks 35 und 36 keine Rolle.An advantage of the method is that the stones used for bricking up the new masonry part can be selected independently of the stone profiles of the old masonry. Since the spaces between the old and new masonry can be irregular, the position of the butt joints and bed joints of the new masonry 35 and 36 is irrelevant.
