Description

Verfahren zur unmittelbaren Herstellung von metallen, insbesondere Eisen Es hat sich herausgestellt, daß man bei dem Arbeiten nach dem Verfahren des Hauptpatents auch Legierungen herstellen kann, die ebenfalls, wie im Hauptpatent, die mehr oder weniger reinen Metalle in Pulverform, als Metallschwamm oder in Form kleiner Kügelchen anfallen.Process for the direct production of metals, in particular Iron It has been found that when working according to the method of Main patent can also produce alloys which, as in the main patent, the more or less pure metals in powder form, as a metal sponge or in the form small globules occur.

So erhält man z. B. durch Glühen einer Mischung von Eisenerz mit einem kieselsäurereichen Stoff, wie Quarzsand usw., sowie Reduktionskohle und geeigneten Zuschlagsstoffen einen lockeren Metallkern, der zum größten Teil aus Ferrosilicium besteht neben geringen Mengen der nicht umgesetzten Mischung.So you get z. B. by annealing a mixture of iron ore with a Silica-rich substance, such as quartz sand, etc., as well as reducing carbon and suitable Aggregates have a loose metal core, which for the most part consists of ferrosilicon consists of small amounts of the unreacted mixture.

Man kann solche und ähnliche Reaktionen unterstützen, indem man geringe Mengen von Stoffen zusetzt, die durch ihre Verbrennung mit dem Sauerstoff des Erzes örtlich hohe Temperaturen hervorrufen, die eine anregende Wirkung auf das übrige Reaktionsgemisch ausüben.You can support these and similar reactions by giving minor Quantities of substances are added by their combustion with the oxygen of the ore cause local high temperatures, which have a stimulating effect on the rest of the area Exercise reaction mixture.

Im oben beschriebenen Falle würde man z. B. mit Vorteil einen geringen Prozentsatz elementaren Siliciums anwenden, wobei gleichzeitig die Möglichkeit besteht, daß etwa nicht oxydiertes Silicium als wertvoller Legierungsbestandteil erhalten bleibt.In the case described above, one would e.g. B. with advantage a low Apply the percentage of elemental silicon, with the possibility of that about non-oxidized silicon obtained as a valuable alloy component remain.

Wenn die Formlinge auf ihrer Wanderung durch den im Gegenstrom beheizten Drehrohrofen in immer höhere Temperatur gelangen, so wird durch die vorhandene Reduktionskohle und das metallische Eisen die vorher durch Oxydation des Siliciums entstandene Si0, wiederum unter Bildung von Ferrosilicium reduziert.When the bricks move through the heated countercurrent Rotary kiln reach higher and higher temperatures, so the existing reducing coal and the metallic iron is Si0, which was previously formed by the oxidation of silicon, in turn reduced to form ferro-silicon.

Der nach dem erwähnten Beispiel hergestellte metallische Kern der Formlinge besteht aus einem leicht zusammengefritteten Pulver, das von sehr kleinen :Metallkügelchen gebildet wird.The metallic core of the manufactured according to the example mentioned Moldings consist of a powder that is lightly fritted together, which is made up of very small : Metal globule is formed.
