Description

Hochfeuerfeste Masse. Die Erfindung bezieht sich auf eine Verbesserung an Ofenauskleidungen, Schmelztiegeln u. dgl. und besteht darin, daß die Auskleidungen oder andere Gegenstände, wie z. B. Schmelztiegel, die großer Hitze zu widerstehen haben, aus dein vulkanischen Produkt hergestellt «-erden, welches in Sandform in vulkanischer Asche in Java und in anderen Gegenden der Welt gefunden wird und welches hauptsächlich aus oxydiertem Titaneisen oder aus der Schlacke desselben besteht, welch letztere gewonnen wird bei Ausführung des Verfahrens zur unmittelbaren Erzeugung von raffiniertem Eisen oder Stahl aus oxydiertem Titaneisen, wie dieses Verfahren in dein Patent 338662 beschrieben ist. Die genannten Produkte werden behandelt und angewendet, wie im nachstehenden beschrieben.Highly refractory mass. The invention relates to an improvement in furnace linings, crucibles and the like. B. Crucibles, which have to withstand great heat, made of your volcanic product "earth", which is found in sand form in volcanic ash in Java and in other parts of the world and which consists mainly of oxidized titanium iron or the slag of the same, whichever the latter is obtained by carrying out the process for the direct production of refined iron or steel from oxidized titanium iron, as this process is described in patent 338662 . The products mentioned are treated and used as described below.

Die Erfindung ist anwendbar bei Ofen allgemein, ist aber vorzugsweise von Nutzen bei elektrischen Ofen, in welchen sehr hohe Temperaturen erzeugt werden. Sie erhöht die Leistungsfähigkeit und Wirksamkeit eines Ofens in sehr beträchtlichem Maße, da es nur erforderlich ist, eine äußere Bekleidung von etwa einem Viertel der sonst üblichen Dicke anzuwenden und eine innere Auskleidung, die so hergestellt ist, wie im nachstehenden be-;chrie@en, wodurch die Hitze bis zu einem beträchtlichen Graefe zusaniniengehalten wird. Um die Erfindung praktisch auszuführen, verwendet man das obengenannte vulkanische Produkt in einem trockenen, fein gekörnten "Zustande für alle Arten von außenseitigen Bekleidungen, wobei diese vorzugsweise in verschiedenen dünnen und begrenzten Lagen ausgeführt werden. Für innenseitige Bekleidungen oder zur Herstellung von Schmelztiegeln, Bodenplatten von Ofen, T'latten zum Auskleiden von Ofen o. dgl. in:ehr pulverisiert inan die obengenannte Schlacke, welche beinahe unschmelzbar und nicht oxvd;ierenc1 ist, mischt und durchfeuchtet sie reit einem sehr geringen Prozentsatz von geeigneten Bindemitteln, um eine Art Paste zu erhalten,worauf sie in eine gewünschte Form gebracht und gepreßt wird.The invention is applicable to ovens in general, but is preferred useful in electric ovens in which very high temperatures are generated. It increases the efficiency and effectiveness of a furnace to a very considerable extent Dimensions, as it is only necessary to have an outer clothing of about a quarter the usual thickness to apply and an inner lining made in this way is, as in the following be; chrie @ en, which brings the heat up to a considerable Graefe is held together. Used to practice the invention the above volcanic product is in a dry, finely grained "state for all types of exterior claddings, these preferably in different thin and limited layers are executed. For inside cladding or for the manufacture of crucibles, furnace base plates, T'latten for lining from furnace or the like in: or pulverizes inan the above-mentioned slag, which almost infusible and not oxvd; ierenc1 is, mixes and moisturizes it rides you very small percentage of suitable binders to obtain a kind of paste, whereupon it is brought into a desired shape and pressed.

Hochfeuerfeste Auskleidungen von elektri-:chen Ofen, Platten Lt. .dgl. aus Titanverbindungen, wie Titanoxyd, Titankarhid, sind hereits vorgeschlagen worden.Highly refractory linings of electrical furnaces, panels Lt. .like of titanium compounds such as titanium oxide, titanium carbide have been proposed here.
