Description
Es ist bekannt, elektrische Öfen in der Weise zu betreiben, daß in einen Mantel aus Metall rohe Elektrodenmasse eingestampft wird, die dann in der Hitze des Ofens gebrannt und leitend wird. Die Elektrode wird in der Nähe des Brennendes mit Tragevorrichtungen und Stromzuführungseinrichtungen versehen.It is known to operate electric ovens in such a way that in a jacket Metal raw electrode mass is pulped, which is then burned in the heat of the furnace and becomes leading. The electrode is placed near the burning end with carrying devices and power supply devices are provided.
Dies Verfahren hat eine Reihe von Nach-This process has a number of disadvantages
to teilen, die sich einesteils daraus ergeben, daß die eigentliche Elektrodenmasse erst in der Nähe des Brennendes leitend wird und daß ferner in der Nähe des Brennendes erhebliche Mengen von Gasen und Dämpfen entstehen, die zu Störungen Anlaß geben. Außerdem ist die Festigkeit der Elektrode ziemlich gering. Erfindungsgemäß wird nun der Betrieb derart geführt, daß die Elektrode aus einzelnen Stücken aus gebrannter Elektrodenmasse nachto share, which result partly from the fact that the actual electrode mass is only in the Near the burning end is conductive and that further in the vicinity of the burning end significant Amounts of gases and vapors are produced which give rise to malfunctions. Also is the strength of the electrode is quite low. According to the invention, the operation now becomes such led that the electrode from individual pieces of burnt electrode mass after
ao Bedarf aufgebaut wird und daß die einzelnen Stücke durch ein geeignetes Bindemittel, z. B. durch rohe Elektrodenmasse, miteinander verkittet werden.ao need is built up and that the individual pieces by a suitable binder, e.g. B. by means of raw electrode mass, cemented together.
Es ist an und für sich bekannt, Elektroden für elektrische Öfen aus einzelnen Stücken zusammenzusetzen, insbesondere aus Reststücken gebrauchter Elektroden, wobei diese Reststücke mit Kitt und besonderen Verbindungsgliedern aus Metall oder Kohle zusammengehalten werden. Dies geschah aber ganz unabhängig vom Betrieb des Ofens. Die aus Reststücken zusammengesetzten einzelnen Stäbe wurden dann zu mehreren, z. B. zu vieren, zu einem Elektrodensatz vereinigt und dann in den Ofen eingesetzt. Bei vorliegender Erfindung aber handelt es sich um die Ermöglichung eines kontinuierlichen Ofenbetriebes, bei dem die an ihrem unteren Ende gefaßte Elektrode fortlaufend, nach Maßgabe des Abbrandes, aufgebaut wird. Die einzelnen Stücke -haben den Querschnitt der Elektrode und nur geringe axiale Längenerstreckung. Es sind vorgeformte und besonders gebrannte und in Vorrat gehaltene Scheiben, die nach Bedarf am oberen Ende der Elektrode unter Zwischenfügung des Kittes aufgesetzt werden.It is known in and of itself to make electrodes for electric ovens from individual pieces assemble, in particular from remnants of used electrodes, these Remnants held together with putty and special connecting links made of metal or carbon will. However, this happened completely independently of the operation of the furnace. The individual pieces assembled from leftover pieces Rods then became several, e.g. B. to four, combined into a set of electrodes and then put in the oven. In the present invention, however, it is the Enabling continuous furnace operation in which the at their lower end Mounted electrode is continuously built up in accordance with the burn-up. The single ones Pieces -have the cross-section of the electrode and only a small axial length extension. There are preformed and specially fired and kept in stock discs that after If required, it can be placed on the upper end of the electrode with the putty in between.
Die einzelnen Scheiben werden zweckmäßig so gestaltet, daß sie mit Zapfen und Aussparungen versehen sind, die einander entsprechen, so daß der Zapfen der einen Scheibe in die Aussparung der anderen beim Aufbau der Elektrode eingreift. Es können aber auch besondere Verbindungsstücke verwendet werden. Besonders vorteilhaft ist die Verbindung durch Stäbe, die durch Längsbohrungen der einzelnen Stücke hindurchgesteckt werden und die eine größere Länge haben als die axiale Länge des Baustückes. Sie werden unter Z Ischenfügung roher Elektrodenmasse durch die Bohrungen hindurchgesteckt und dienen nicht nur zur Erhöhung der Festigkeit, sondern auch der Leitfähigkeit.The individual disks are expediently designed so that they are provided with pegs and recesses are provided, which correspond to each other, so that the pin of one disc in the recess of the other during construction the electrode engages. However, special connectors can also be used will. The connection by rods through longitudinal bores is particularly advantageous of the individual pieces are pushed through and which have a greater length than the axial length of the component. They are made using raw electrode material inserted through the holes and not only serve to increase the strength, but also the conductivity.
Der Aufbau der Elektrode gestaltet sich hierbei äußerst einfach. Die einzelnen Scheiben können leicht gehandhabt und aufgesetzt werden. Die Leitfähigkeit der Elektrode ist,The structure of the electrode is extremely simple. The individual discs can be easily handled and put on. The conductivity of the electrode is
besonders wenn man längere, durchlaufende Stäbe verwendet, sehr viel höher als die einer ganz aus roher Elektrodenmasse bestehenden sogenannten selbstbrennenden Elektrode. Aus diesem Grunde und wegen der großen Festigkeit der ganzen Elektrode ist ein Metallmantel für die Elektrode nicht mehr unbedingt erforderlich. Störungen durch Gase und Dämpfe beim Heißwerden der Elektrode sind so gutespecially if one uses longer, continuous rods, much higher than one So-called self-burning electrode made entirely of raw electrode material. the end For this reason and because of the great strength of the entire electrode, there is a metal jacket no longer absolutely necessary for the electrode. Gas and vapor interference when the electrode gets hot is so good
ίο wie gar nicht mehr vorhanden. Der ganze Betrieb der Dauerbrandelektrode gestaltet sich äußerst einfach, und reinlich. Auch der Transport und die Aufbewahrung der einzelnen Baustücke ist einfacher als der der rohen Elektrodenmasse, die zum Aufbau der Elektrode am Ofen selbst sonst verwendet wird. In Fig. ι ist ein Bauelement für die Elektrode beispielsweise dargestellt. Fig. 2 zeigt den Zusammenbau eines ähnlichen Elements mit einer Elektrode. Darin bedeutet a die Elektrode, b das Bauelement, c das Bindemittel, d einen Kohlestab, der die Bauelemente durchdringt.ίο like no longer available. The whole operation of the permanent burn electrode is extremely simple and clean. The transport and storage of the individual components is also easier than that of the raw electrode mass, which is otherwise used to assemble the electrode on the furnace itself. In Fig. Ι a component for the electrode is shown, for example. Fig. 2 shows the assembly of a similar element with an electrode. A therein the electrode, b represents the component, the binder c, d a carbon rod, which penetrates the elements.
