Description
Verfahren zum Gewinnen von Nickel oder Ferronickel aus nickelbaltigem Walzensinter. Die Erfindung betrifft ein Verfahren zur Herstellung von nickelreichen Eisenlegierungen oder reinem Nickel aus nickelhaltigem Walzensinter.Process for obtaining nickel or ferronickel from nickel-containing Roller sintering. The invention relates to a method for the production of nickel-rich Iron alloys or pure nickel from nickel-containing roller sintering.
Es ist bekannt, Eisennickellegierungen unmittelbar aus den Rohstoffen, wie gerösteter Nickelstein oder Nickelspeise, sowie bei der Nickelstahlverarbeitung abfallenden Hammerschlag und Walzensinter, die vorwiegend aus Oxyden des Eisens und geringen Mengen Nickeloxyd bestehen oder bestehen sollen, durch reduzierendes Schmelzen herzustellen, indem die Nickel- und Eisenoxyd enthaltenden Rohstoffe mit der für die Reduktion des Nickeloxydes ausreichenden, für das neben dem Nickeloxyd vorhandene Eisenoxyd aber unzureichende Menge Kohlenstoff verschmolzen werden.It is known to produce iron-nickel alloys directly from the raw materials, such as roasted nickel stone or nickel food, as well as in nickel steel processing falling hammer blows and roller sintering, which are predominantly made up of oxides of iron and small amounts of nickel oxide consist or should consist of reducing Produce smelting by using raw materials containing nickel and iron oxide that which is sufficient for the reduction of the nickel oxide, for that in addition to the nickel oxide existing iron oxide but insufficient amount of carbon are fused.
Bei einem weiteren Verfahren, Nickelstahl mit den eben erwähnten Rohstoffen herzustellen, wird das erford7erliche Roheisen in einem gebräuchlichen Ofen mit basischer Auskleidung eingeschmolzen oder geschmolzen eingebracht und dann Walzensint#er zugesetzt. Dieser Rohstoff dient dann einmal als Frischmittel, indem er den zur Oxydation des im Roheisen enthaltenen Kohlenstoffes und Siliciums nötigen Sauerstoff liefert, und dann als Mittel zur Zuführung von -Nickel, dessen Oxyd bei basischer Reaktion der Schmelze noch vor den Oxyden des Eisens seinen Sauerstoff verliert.In another process, nickel steel with the raw materials just mentioned the required pig iron is put in a conventional furnace with basic lining melted or melted and then roller sintered added. This raw material then serves as a fresh agent by adding the Oxidation of the carbon and silicon contained in the pig iron, which is necessary for the oxygen supplies, and then as a means of supplying -Nickel, whose oxide is more basic Reaction of the melt before the oxides of iron lose their oxygen.
Diese 'bekannten Verfahren behandeln die Herstellung von Ferronickel und Nickelstahl unmittelbar aus Rohstoffen durch reduzierendes Schmelzen.These known processes deal with the manufacture of ferronickel and nickel steel directly from raw materials through reducing melting.
Gegenstand der Erfindung ist ein Verfahren zum Gewinnen von Nickel oder Ferronickel aus nickelhaltigem Walzensinter unter Verwendung von Eisen- oder Stahlspänen, besonders aber Nickelstahlspänen, ohne Zusatz von Roheisen.The subject of the invention is a process for the extraction of nickel or ferronickel from nickel-containing roll sintering using iron or Steel shavings, but especially nickel steel shavings, without the addition of pig iron.
Das Verfahren wird derart ausgeführt, daß nickelhaltiger Walzensinter mit Eisen- oder Stahlspänen, insbesondere mit Nickelstahlspänen, briketfiert und in einem beliebigen Ofen niedergeschmolzen wird. Das in dem Walzensinter enthaltene metallische Nickel oder Nickeloxyd wird dabei in flüssigem Zustande gewonnen und ohne Kohlenstoff durch metallisches Eisen zu Nickel reduziert und setzt sich mit dem überschüssigen Eisen, weil es spezifisch schwerer als das geschmolzene Eisenoxyd oder Oxydul ist, am Boden ab.The method is carried out in such a way that nickel-containing roll sintering with iron or steel shavings, especially with nickel steel shavings, briquetted and is melted down in any furnace. That contained in the roller sinter metallic nickel or nickel oxide is obtained in the liquid state and reduced to nickel by metallic iron without carbon and settles with the excess iron, because it is specifically heavier than the molten iron oxide or Oxydul is off at the bottom.
