Die Erfindtuig bezieht sich, auf ein Verfahren, zur Herstelhtng ekier Metallegierung unter Verwendung einer Verbindung des Metalle, das mit dem Gruiradmetali zu legieret» ist, sowie eines Grundmetalls, das auf die vorerwähnte Verbindung reduzierend wirkt.The invention relates to a method of making a metal alloy using a compound of the metal that is to be alloyed with the Gruiradmetali, as well as a base metal that has a reducing effect on the aforementioned compound.
Im folgenden wird die Erfindung bed der Herstellung eimer Eisen-Niekel-Legiertuig unter Verwendung eines nickelhaitigen Eisenerzes erläutert. Es können, jedoch auch Erze, die VerbindOngen anderer Metalle, wie z. B. Kupfer und Molybdän, enthalten,' verwendet werden. Ebenso können auch Oxyde oder Salze von Metallen, wie z. B. von Nickel, Kupfer oder Molybdän, verwendet werden.In the following, the invention is used in the manufacture of iron-Niekel alloy a nickel-containing iron ore explained. The compounds can, however, also contain ores other metals, such as B. copper and molybdenum, 'can be used. Likewise can also Oxides or salts of metals, such as. B. of nickel, copper or molybdenum can be used.
Auf Kuba und anderswo werden Eieenexze gefunden, welche geringe Anteile an .Nickel, z. B. 1 bis 2*U oder auch ein weutg mehr, «nthaltetu Diese Erze werden in einen, geeigneten Ofen, wie 2. B. einen rotierenden. Schmelzofen, eingebracht und diarin geschmolzen. Das geschmolzene Erz befindet sich dann hn Zustande einer geschmolzenen Eisensilikatechtacke mit einem Gehalt an Tiickeloxyd. Die Scrilacke wird aus dem Ofen in einen Behälter abgezogen.In Cuba and elsewhere Eieenexze are found, which small amounts of .Nickel, z. B. 1 to 2 * U or even a little more. These ores are kept in a suitable furnace, such as a rotating furnace. Melting furnace, brought in and melted in it. The molten ore is then in the state of a molten iron-silicate bag with a content of titanium oxide. The scrilacke is withdrawn from the oven into a container.
Das Grundmetall, welches auf die Verbindung des Legierungsmetalls in> der Schlacke reduzierend wirkt, wird gesondert, geschmolzen. Beispielsweise kann, wenn die Schlacke Nickeloxyd enthält, als Grundmetall ein solches der Eisengruppe verwendet werden, und zwar geschmolzenes Roheisen oder ein sonstiges nichtgefeintes Eisen. Da» Grundiiietafl kann aber auch bis zn einen· gewissen Ausmaß gefeint werden, wie z. B. durch Frischen in einer Bessemer Birne oder in einem Siemens-Martin-Ofen oder auch ia einem elektrischen Ofen. . , The base metal, which has a reducing effect on the compound of the alloy metal in> the slag, is separately, melted. For example, if the slag contains nickel oxide, it can be used as the base metal one of the iron group can be used, namely molten pig iron or something else unfinished iron. The basic element can, however, also be refined to a certain extent, such as z. B. by freshening in a Bessemer pear or in a Siemens-Martin oven or in general an electric oven. . ,
Die geschmolzene Schlacke -und das geschmolzene Grundmetajl ,werden miteinander vermischt, und die beiderseitigen Temperaturen wenden so geregelt, daß bei der Zumischung des Grundmetalk das letztere aus dem geschmolzenen Zustand, in eine Masse feinster fester Teilchen übergeführt wird. Dieae Teilchen bieten der geschmolzenen Schlacke zur wirksamen Reduktion der Verbiiwlüng des Legierungsmetall« eine große Oberfläche dar; die Verbindung wird reduziert, and das Legierungsmetall lagert sich auf <ten> erwähnten ,Teilchen ab. Bandelt.es sich bei der Verbindung um Nickeloxyd und . ist das Grundmetall Eisen, dann wird das Nickeloxyd reduziert, und das Nickel lagert sich in. metoHrser^r^Form. auf den Eisenteiichen ab, Das Produkt ist das,, was. man .wohl als eine mehthomogepe Legierung ,bezeichnen könnte; sie-besteht in, der Sauptsacfae, aas. ^instep- Teilchen des. Grundmetalls, die mit dem Legiere^stfietall bedeckt'sind. , '.·'.. ..'it.'[.. ».'IVh.'·!^»-The molten slag and the molten base metal are mixed together, and the temperatures on both sides are regulated so that when the base metal is added, the latter is converted from the molten state into a mass of extremely fine solid particles. The particles present a large surface area to the molten slag for effective reduction of the deterioration of the alloying metal; the bond is reduced and the alloy metal is deposited on the <ten> mentioned particles. Bandelt.es in the connection to nickel oxide and. if the base metal is iron, the nickel oxide is reduced and the nickel is stored in a metal form. on the iron ponds, the product is that, what. one could call it a mehthomogepe alloy; it-consists in, the Sauptsacfae, aas. ^ instep- particles of the base metal, which are covered with the alloy ^ stfietall. , '. ·' .. ..

schmelzflüssiges Eisen in eine dünnftÜBsige Schlacke, die Oxyde der dem Grundimetall zuxulegierendcn Metalle, also z. B, Nickeloxyd, enthält, so einzumischen, d&ß infolge dear innigen Vermischung von flüssigem Metall und flüssiger Schlacke, schnelle I^gierungsbiIduog erfolgt (deutsche Patentschrift 676 778), und somit also auch eine Gmndmetalt-' schmelze mit einer Schlackeoschmelze zum Vermischen zu bringen. Bei dieser bekannten Verfahrungsweise bleiben jedoch die beiden Mischkomponenten während der Dauer des Mischvorganges flüssig, während bei dem erfindungsgemäßen Verfahren das zu legierende Grandmetall durch eine entsprechend gesteuerte Temperaturregelung während des Miechvorganges in feinster Zerteilung zu einer Vielzahl von Festkörperchen erstarrt. Durch dieses VerfahrenOTaerkmaI unterscheidet sich das erfutdutigsgemäße Verfahren wesentlich von dem obigen bekannten Verfahren, gegenüber weichem es überdies ausbeutemäßig überlegen ist und somit wirtschaftlicher arbeitet. Es ist also an sich nicht mehr neu, das Vermischen der geschmolzenen Schlacke, welche einen erheblichen Anteil ,einer Verbindung des Metalls, das mit dem Grundmetall- legiert werden soll, enthält, mit dem geschmolzenen' Grundmetall, das auf die Verbindungmolten iron into a thin slag, the oxides of which the base metal is alloyed Metals, e.g. B, nickel oxide, contains, to be mixed in, as a result of the intimate mixing of liquid metal and liquid slag, rapid I ^ gierungsbiIduog takes place (German patent specification 676 778), and thus also a basic metal melt with a slag melt for mixing bring to. In this known procedure, however, the two mixed components remain liquid for the duration of the mixing process, while in the method according to the invention the grand metal to be alloyed by a correspondingly controlled temperature control during of the Miech process solidified in the finest fragmentation to a multitude of solid bodies. Because of this MethodOTaerkmaI, the actual method differs significantly from the above known method Processes to which it is moreover superior in terms of yield and thus works more economically. So it is in itself no longer new, the mixing of the molten slag, which makes a significant difference Part of a compound of the metal that is to be alloyed with the base metal, with the molten 'base metal that is on the compound
