Description
Eisenpulver, Eisenmehl u.dgl., welches in der chemischen Industrie zu Reduktions- und anderen Zwecken Verwendung findet, wurde bisher entweder aus Eisenfeilspänen oder durch Zerkleinern von mehr oder . weniger hartem Eisen, Stahl oder Roheisen gewonnen. Diesem Herstellungsverfahren haften jedoch technische und wirtschaftliche Mängel an. Sie bestehen darin, daß die Erzeugung wenigIron powder, iron flour and the like. Which in the chemical industry for reduction and used for other purposes, was either made of iron filings or by crushing more or. less hard iron, steel or pig iron. However, technical and economic defects are inherent in this manufacturing process. They consist in generating little
ίο ergiebig und. daß, wenn die Herstellung des Pulvers oder Mehles durch Zerkleinerung erfolgt, die Arbeit mehr oder weniger schwierig ' ist, je nachdem Eisen, Stahl oder Roheisen gepulvert werden soll. Zudem enthält das zur Herstellung von Eisenpulver verwendete Eisen meistens größere Mengen Kohlenstoff, Silizium, Phosphor, Schwefel u. dgl., welche die Verwendung von Eisenpulver zu Reduktionszwecken in Frage stellen können. ίο productive and. that if the manufacture of the Powder or flour is made by grinding, the work more or less difficult 'is powdered iron, steel or pig iron, depending on the condition shall be. In addition, the iron used to produce iron powder usually contains large amounts of carbon, silicon, Phosphorus, sulfur and the like, which may question the use of iron powder for reduction purposes.
ao Gegenstand der Erfindung ist nun ein Verfahren zur Herstellung " von Eisenpulver, welches sich als vorteilhafter erweist als die bisherigen. ■ Das' neue Verfahren besteht darin, daß nicht Eisen im gewöhnlichen Sinne, sondern ein Übergangsprodukt vom Eisenerz zum Eisen, nämlich Eisenschwamm in Stückform, durch Mahlen, Stampfen u. dgl. und im Anschluß hieran durch magnetische Scheidung und Siebung in Pulverform übergeführt wird, oder daß die bei der Bearbeitung von Eisenschwamm abfallenden Rückstände einer wei-' teren Verarbeitung bis zum gewünschten Feinheits- und Reinheitsgrade unterworfen werden.The invention also relates to a process for the production of "iron powder, which proves to be more advantageous than the previous ones. ■ The 'new procedure exists in the fact that not iron in the ordinary sense, but a transitional product from iron ore to iron, namely sponge iron in lump form, by grinding, stamping and the like Connection to this is converted into powder form by magnetic separation and sieving, or that the residues that fall off when working with sponge iron Subsequent processing to the desired degree of fineness and purity will.
Eisenschwamm ist ein sehr reines Produkt. Der für seine Herstellung verwendete Rohstoff . ist praktisch reines Eisenoxyduloxyd (Fe3 O4), welcher durch Anreicherung von Magnesiteisen gewonnen und in Mischung mit Kohle in Topfen oder Retorten mittels Generatorgas reduziert wird. Die Verunreinigungen beschränken sich auf sehr geringe Mengen mechanisch eingeschlossener Kohleteilchen, Oxyde, Schlacken und Silikate. Gebundenen Kohlenstoff, Mangan, Silizium, Phosphor, Schwefel enthält Eisenschwamm weniger als andere Eisensorten, mit Ausnahme von Elektrolyteisen. Der Eisenschwamm besitzt auch besondere physikalische Eigenschaften, die ihn ,für die Zerkleinerung geeignet machen. Sein Gefüge besteht aus lose aneinanderhängenden, mit einem dünnen Oxydhäutchen überzogenen Eisenkörnern, die, trotzdem sie aus fast chemisch reinem · Eisen bestehen, ziemlich spröde sind und in kleinste Teilchen zerfallen. .Sponge iron is a very pure product. The raw material used for its manufacture. is practically pure iron oxide (Fe 3 O 4 ), which is obtained through the enrichment of magnesite iron and reduced in a mixture with coal in pots or retorts by means of generator gas. The impurities are limited to very small amounts of mechanically entrapped coal particles, oxides, slags and silicates. Sponge iron contains less bound carbon, manganese, silicon, phosphorus and sulfur than other types of iron, with the exception of electrolyte iron. The sponge iron also has special physical properties that make it suitable for grinding. His G e add consists of loosely hanging, covered with a thin Oxydhäutchen iron grains, although they consist of almost chemically pure · iron, are quite brittle and break down into tiny particles. .
Um den zerkleinerten Eisenschwamm von den ihm mechanisch beigemengten Körpern zu trennen, wird er einer magnetischen Scheidung unterworfen. Das Pulver wird dadurch von Schlacken, Silikaten, Oxyden, mechanisch beigemengten Kohleteilchen befreit, enthält aber noch alles nichtreduzierte Magneteisen, da dieses auch magnetisch ist.About the crushed sponge iron from the bodies mechanically added to it to separate, he will be subjected to a magnetic divorce. The powder will thereby freed from slag, silicates, oxides, mechanically admixed coal particles, but still contains all non-reduced magnetic iron, as this is also magnetic.

Zur Reduktion, welche in einer reduzierenden Gasatmosphäre vorgenommen wird, kann stückförmiger, aber auch pulverisierter Eisenschwamm genommen werden.
