Description

Verfahren und Einrichtung zur Herstellung von Graphit im elektrischen Ofen. Die wesentlichen Vorgänge bei der Herstellung künstlichen Graphites' oder bei der Reinigung natürlichen Graphites durch elektrische Erhitzung sind bekannt.Process and device for the production of graphite in the electrical Oven. The essential operations in the manufacture of artificial graphites' or in the purification of natural graphites by means of electrical heating are known.

Nicht bekannt aber war bis heute, daß die Umwandlung von Kohle, Koks, 'Anthracit o. dgl. Ausgangsmaterialien in Graphit bei einem gewissen Unterdruck wesentlich Teich= ter und schneller und vor allem bei wesentlich niederer Temperatur als bei Atmosphärendruck vor sich geht.. Die logische Folge ist eine ganz bedeutende Stromersparnis.But it was not known to this day that the conversion of coal, coke, 'Anthracite or similar starting materials in graphite at a certain negative pressure much pond = ter and faster and above all at a much lower temperature than what goes on at atmospheric pressure. The corollary is a very significant one Power saving.

Der Unterdruck wird- praktisch erreicht, indem man den ganzen Ofen mit einem aus starkem Eisenblech luftdicht abschließenden Kasten umbaut, der zur besseren Ausnützung und Konzentration der Wärme mit Asbest oder sonstigen wärmeisolierenden Materialien ausgefüttert sein-kann. Von Vorteil für den praktischen Betrieb ist es, den Kasten so zu konstruieren, daß man ihn nach jedem Brand leicht durch einen Kran abnehmen kann. Der Kasten steht durch Rohre; die an geeigneten Stellen angeschweißt sind, mit einer Luftpumpe in Verbindung, die den für die verschiedenartigen Verhältnisse am.besten geeigneten Unterdruck in dem Kasten stets gleichmäßig aufrecht erhält.The negative pressure is practically achieved by opening the entire furnace with an airtight box made of strong sheet iron, which leads to the Better utilization and concentration of the heat with asbestos or other heat-insulating Materials can be lined. Is beneficial for practical operation it is to construct the box in such a way that it can be easily pushed through after every fire Crane can take off. The box stands through pipes; which are welded in suitable places are connected to an air pump that is suitable for the various conditions the most suitable negative pressure in the box is always maintained evenly.

Durch die Saugwirkung der Pumpe werden. auch die im Innern des Ofens entstehenden Gase abgesaugt; sie müssen sich nicht wie bisher durch eine gewisse Spannung aus dem Ofeninnern ihren Weg mühsam nach außen bahnen.Be by the suction of the pump. also those inside the furnace evacuated gases; they don't have to go through a certain amount as before Tension from the inside of the furnace laboriously pave its way to the outside.

Gleichzeitig mit dem Absaugen der Gase wird auch die Wanderung der zur Graphit= Bildung unbedingt 'erforderlichen dampfförmigen Kontaktsubstanzen vom Kern .des . Ofens nach der Wandung sehr erleichtert, und die Graphitbiidung# erfährt dadurch eine weitere Beschleunigung.Simultaneously with the suction of the gases, the migration of the for graphite = formation of absolutely necessary vaporous contact substances from Core .des. Furnace after the wall very relieved, and the graphite formation # experiences thereby a further acceleration.

Nach dem bisher geübten Verfahren ver= flüchtigten sich die bei der Bildung des Graphites entstehenden Kohlenoxydgase bzw. wurden nutzlos abgebrannt. Das vorliegende Verfahren ermöglicht deren technische Verwertung, was bei der erheblichen Menge einen nicht zu unterschätzenden Vorteil bietet.According to the previously practiced procedure, those at the Carbon oxide gases formed during the formation of graphite or were uselessly burned off. The present process enables their technical recovery, which is the case with the considerable Quantity offers an advantage that should not be underestimated.
