Description
Verfahren zur Herstellung von Kohlenelektroden. Die gebräuchlichen Kohlenelektroden bestehen nicht aus einer einheitlichen homogenen Masse, sondern zu den kohlenstoffhaltigen Grunidbestandteilen werden für den Trocken- und Glühprozeß, um die Entgasung der in der Kohlenelektrode enthaltenen flüchtigen Teer- und Gasbestandteile zu erleichtern; solche Kohlenstoffverbindungen in verschiedenartigen Körnungen zugesetzt, welche vorher entgast worden- sind, z. B. entgaster Petrodkoks und' entgaster Anthrazit. Diese entgasten Stoffe weisen nun infolge ihrer verschiedenen Herkunft und Vorbehandlung auch verschiedene Porositäten auf. Sie haben aber auch in physikalischer und chemischer Beziehung verschiedene Eigenschaften in Bezug auf den Kohlenstoffgehalt, den Gehalt an Verunreinigungen, ihre Dichte und ihr Verhalten im Feuer und namentlich ihr Verhalten gegenüber der Einwirkung des elektrischen Stromes.Process for the production of carbon electrodes. The common ones Carbon electrodes do not consist of a uniform, homogeneous mass, but rather the carbonaceous base components are used for the drying and annealing process, around the degassing of the volatile tar and gas components contained in the carbon electrode to facilitate; such carbon compounds are added in various grain sizes, which have previously been degassed, e.g. B. degassed petrodcoke and degassed anthracite. These degassed substances are now due to their different origins and pretreatment also have different porosities. But they also have in physical and chemical Relationship various properties in terms of carbon content, the content of impurities, their density and their behavior in fire and especially their behavior against the action of the electric current.
Es ist bekannt, bei der Herstellung von Kohlenelektroden gewisse Bestandteile des Gemisches in feiest vermahlener Form, andere, insbesondere entgasten Anthrazit, in Körnungen zu verwenden.-- Der Zweck der vorliegenden Erfindung ist, .die verschiedenen chemischen und physikalischen Eigenschaften in den Bestandteilen der Kohlenelekfirode möglichst gleichmäßig zu gestalten.It is known that certain components are used in the manufacture of carbon electrodes of the mixture in finely ground form, others, especially degassed anthracite, to be used in grits - The purpose of the present invention is to identify the various chemical and physical properties in the components of the carbon electrode as evenly as possible.
Zu diesem Zweck wird vorgeschlagen., die für die Entgasung erforderlichen Beimengungen, z. B. Petrolkoks und-, Anthrazit, im rohen Zustande fein zu mahlen,- innig zu mischen und gegebenenfalls unter Hinzuführung von Graphit und Teer als Bindemittel in dieser innigen Mischung zu pressen. Die auf diese Weise gewonnenen Briketts werden dann in Entgas.ungsöfen bekannter Art entgast und hierauf in verschiedenen Körnungen den Grundbestandteilen der Masse für die Herstellung der Kohlenelektrode zugesetzt. Die Grundbestandteile werden auf dieselbe Weise zu einem einheitlichen Körper durch innige Mahlung und Vermischung vorher aufbereitet, und es werden auch diieselben Bestandteile verwendet, welche durch den Aufbereitungsprozeß sich ergeben.For this purpose it is suggested that the necessary for degassing Additions, e.g. B. petroleum coke and -, anthracite, to be finely ground in the raw state, to mix intimately and optionally with the addition of graphite and tar as To press binder in this intimate mixture. The ones obtained in this way Briquettes are then degassed in degassing ovens of a known type and then in different ones Grains are the basic components of the mass for the production of the carbon electrode added. The basic components become one unified in the same way Body prepared beforehand by intimate grinding and mixing, and there are also uses the same ingredients that result from the treatment process.
Auf diese Weise ist es möglich, sowohl die Grundbestandteile als auch; die für die Entgasung wichtigen körnigen Zusätze in einheitliche Zusammensetzung zu bringen und damit Elektroden herzustellen, welche in ihrer ganzen, der Einwirkung des elektrischen Stromes und der damit erzeugten Hitze wirksamen Fläche und Struktur homogen erscheinen. -In this way it is possible to use both the basic components as well as; the granular additives important for degassing in a uniform composition to bring and thus to produce electrodes, which in their whole, of the action of the electric current and the heat generated by it, effective surface and structure appear homogeneous. -
