Description
<Desc/Clms Page number 1>
Verfahren zur Herstellung von Neusilber oder anderen Kupfer und Nickel enthaltenden
Legierungen aus einer eisenhaltigen Metallmischung.
In dem Stammpatent Nr. 42361 ist vorgesehen, das in der Metallegierung enthaltene Eisen durch Luft oder andere oxydierende Gase zn oxydieren. Unter gewissen Voraussetzungen,
EMI1.1
folgender Weise herbeigeführt worden :
Die eingeschmolzene oder flüssig in den Ofen gebrachte oder endlich eine nach dem
EMI1.2
Eisenoxydul umandeln und gleichzeitig eine Reduzierung der Metalloxyde des Kupfers und Nickels und damit eine Anreicherung der Legierung eintreten. Bekanntlich wird in der Eisenindustrie, z. B. hoi dem Puddel-und Martinverfahren, eine Verbrennung der dem schmiedbaren Eisen schädlichen Beimengungen des Rohmetalles durch Zusatz von Eisen- oxyden bewirkt.
Hier sollen die beigemengten Metalloide (C, Si, P, S) entfernt werden, während es sich bei der Erfindung um die Entfernung der letzten Reste eines Metalles Handelt - Es ist ferner die Einführung von Oxyden der zu behandelnden Metalle in die Schmelze bekannt, um die Oxydationswirkung der Luft zu steigern. Das Einblasen von Luft usw. bewirkt nun eine zu starke Oxydation der Metalle, welche rein gewonnen werden sollen, und führt nach dem Gesetz der Massenwirkungen zu MetaDverIusten, be- sonders wenn nur geringe Mengen des verunrein@@@nder Metalles vorhanden sind.
Dadurch, dass durch das Mitoinblasen der Oxyde in den bekannten FäDen die Oxydationswirkung der Luft gesteigert wird, soll gerade das bewirkt werden, was bei der Erfindung verhütet werden soll.

Process for the production of nickel silver or other copper and nickel containing
Alloys made from a ferrous metal mixture.
The parent patent no. 42361 provides for the iron contained in the metal alloy to be oxidized by air or other oxidizing gases. Under certain conditions,
EMI1.1
in the following way:
The melted or liquid brought into the oven or finally one after the
EMI1.2
Convert iron oxide and at the same time a reduction in the metal oxides of copper and nickel and thus an enrichment of the alloy occur. It is known that in the iron industry, e.g. B. hoi the puddle and Martin process, a combustion of the additions of the raw metal harmful to the malleable iron caused by the addition of iron oxides.
Here the added metalloids (C, Si, P, S) are to be removed, while the invention concerns the removal of the last remnants of a metal. The introduction of oxides of the metals to be treated into the melt is also known to to increase the oxidizing effect of the air. The blowing in of air etc. now causes too strong an oxidation of the metals which are to be extracted in pure form and, according to the law of mass effects, leads to metal losses, especially if only small amounts of the contaminated metal are present.
The fact that the oxidizing effect of the air is increased by the mitoin blowing of the oxides in the known threads is intended to bring about exactly what is to be prevented in the invention.
