Description

Verfahren zum Herstellen von nickelreichen Eisenlegierungen. Die Erfindung betrifft ein Verfahren zum Herstellen von nickelreichen Eisenlegierungen aus Stahlschrott mit niedrigem Nickelgehalt. Große Mengen Nickelstahlschrott von Kriegsschiffen, Geschützen, Abfällen aus der Automobilfabrikation stehen zur Verfügung. Nickelstahlschrott ist aber wegen des niedrigen Nickelgehaltes nur schwer zu verwenden und infolgedessen kaum abzusetzen, auch wesentlich niedriger im Geldwert als gewöhnlicher Schrott. Durch das Verfahren nach der Erfindung soll auch dieser Abfall oder Schrott für die Wirtschaft wieder nutzbar gemacht werden, nachdem bereits Verfahren vorgeschlagen sind, Späne, Sinter, Hammerschlag , welche Nickel enthalten, auf nickelreiche Eisenlegierungen zu verarbeiten. Das metallische Eisen der Nickelstahlspäne hat man danach durch Zuführung von Luft oder reinem Sauerstoff ganz oder teilweise oxydiert, wobei die Oxydationswärme so hoch getrieben wird, daß die Masse geschmolzen wird. Hierbei verschlackt das oxydierte Eisen, während das Nickel als solches oder in Form einer Eisennickellegierung gewonnen wird.Process for making nickel-rich iron alloys. The invention relates to a method for producing nickel-rich iron alloys from steel scrap with low nickel content. Large quantities of nickel steel scrap from warships, Guns, waste from automobile production are available. Nickel steel scrap but is difficult to use because of the low nickel content and consequently Hard to sell, also significantly lower in monetary value than ordinary junk. By the method according to the invention, this waste or scrap for The economy will be made usable again after procedures have already been proposed are, chips, sinter, hammer blows, which contain nickel, on nickel-rich iron alloys to process. The metallic iron of the nickel steel shavings is then through Supply of air or pure oxygen completely or partially oxidized, the Oxidation heat is driven so high that the mass is melted. Here The oxidized iron is slagged, while the nickel as such or in the form of a Iron nickel alloy is obtained.

Auch ist das Verblasen von Rohnickel, welches Eisen enthält, im S.chmelzfiuß zwecks Abscheidens des Eisens bekannt. Um den Nickelstahlsc'hrott, der in Form von Panzerplatten, Kurbelwellen u. dgl. in großen Stücken vorhanden ist, zu verarbeiten, müssen diese zunächst in Späne zerlegt werden, um :nach dein angedeuteten Verfahren oxydiert zu werden.The fading of crude nickel, which contains iron, is also in the melt known for the purpose of separating the iron. To the nickel steel scrap that is in the form of Armor plates, crankshafts and the like are available in large pieces to process, these must first be broken down into chips, in order to: according to your indicated procedure to be oxidized.

Nach .der Erfindung wird aber dieser nikkelhaltig ;e Stahlschrott in einem beliebigen Ofen niedergeschmolzen. Das flüssige Bad wird dann in der Bessemerbirn.e einem Oxydationsvorgang unterworfen, wobei ein großer Teil des Eisens oxydiert wird, während das Nickel in den übrigbleibenden geringen Eisenmengen zurückbleibt.According to the invention, however, this becomes nickel-containing; e steel scrap melted down in any furnace. The liquid bath is then in the Bessemerbirn.e subjected to an oxidation process, whereby a large part of the iron is oxidized, while the nickel remains in the remaining small amounts of iron.

Das Neue besteht somit darin, daß der Stahlschrott -mit niedrigem Nickelgehalt im B,essemerverfahren verblasen wird, wobei das Eisen oxydiert und so eine Nickeleisenverbindung mit hohem Nickelgehalt .erzeugt wird.The novelty is that the steel scrap -with low Nickel content in the B, essemerverfahren is blown, with the iron being oxidized and thus producing a nickel-iron compound with a high nickel content.
