Description

Verfahren zur Verarbeitung feinkörniger Eisenerze. Die Erfindung betrifft ein Verfahren zur Verarbeitung feinkörniger Eisenerze, z. B. Magnetit o. dgl. Man hat zu diesem Behufe bereits Eisenkoksbrikette dadurch hergestellt, daß man das feine Erz mit gepulverter Kohle gemischt und entgast hat; aber das nach diesem Verfahren hergestellte Erzeugnis hat sich nicht als zur unmittelbaren Verarbeitung im Hochofen geeignet erwiesen, da es nicht die genügende Tragfähigkeit besaß.Process for processing fine-grain iron ores. The invention relates to a method of processing fine-grain iron ores, e.g. B. magnetite or the like. Man has already made iron coke briquette for this purpose by fine ore mixed with powdered coal and degassed; but that after this procedure The manufactured product has not proven to be suitable for immediate processing in the blast furnace proved suitable because it did not have sufficient load-bearing capacity.

Um diesen Zweck zu erreichen, bedient sich der Erfinder folgender Maßnahmen: Der Erzkoks wird gelöscht und aufgehäuft. Dann wird Schwefeldioxydgas oder Chlorgas durchgeleitet, oder es wird über den Kokshaufen eine kaustische Alkalilösung oder Seewasser gegossen, wobei das Eisen, das im Koks enthalten ist, in dem Maße löslich gemacht wird, daß die Poren des Kokses sich mit Eisensalz füllen; hierauf wird das Gut gelüftet, so daß Eisenoxyd in der Masse (als Bindemittel) entsteht.To achieve this purpose, the inventor makes use of the following Measures: The ore coke is extinguished and piled up. Then it becomes sulfur dioxide gas or chlorine gas passed through, or a caustic alkali solution is passed over the coke pile or sea water poured, with the iron, which is contained in the coke, in the measure solubilized so that the pores of the coke fill with iron salt; on this the material is ventilated so that iron oxide is formed in the mass (as a binding agent).

Die Einwirkung vom Schwefeldioxyd oder Chlorgas hat zur Folge,. daß das Eisen im Koks in Eisensulfat oder Eisenchlorid übergeführt wird, während die Alkali'auge oder das Seewasser zusammen mit dem Sauerstoffgehalt und der Feuchtigkeit und Kohlensäure der Luft eine teilweise Oxydation des vorher reduzierten Eisens bewirken. Eg entstehen z. B.: Fee 03, Fe (0H)2, Fe (OH) (HCO3) oder Fe (0H)2 Diese Verbindungen besitzen eine starke Bindekraft und verwandeln die Koksstücke in eine harte, zusammenhängende Masse, die in einem Schmelzofen unter Beigabe geeigneter Flußmittel, lediglich mit Hilfe der Kohle, die in dem Brikett enthalten ist, geschmolzen wird.The effect of sulfur dioxide or chlorine gas has the consequence. that the iron in the coke is converted into iron sulfate or ferric chloride, while the Alkali eye or the sea water together with the oxygen content and the humidity and carbonic acid in the air a partial oxidation of the previously reduced iron cause. Eg arise z. E.g .: Fee 03, Fe (0H) 2, Fe (OH) (HCO3) or Fe (0H) 2 These Compounds have a strong binding force and turn the coke pieces into one hard, coherent mass, which in a melting furnace with the addition of suitable Flux, melted only with the help of the charcoal contained in the briquette will.
