  Verfahren zur unmittelbaren Herstellung von desoxydierten Legierungen des Kupfers. 



   Im Gegensatz zu dem üblichen Verfahren, nach welchem sauerstoffhaltige Metalllegierungen, die man irgendwie erhalten hat, durch Zusatz eines leicht oxydierbaren Elements, wie Phosphorkupfer, Ferromangan, Ferrosilizium, Magnesium, Kohlenstoff, und zwar in der Regel in der Giesspfanne   desoxydiert   werden, soll nach der Erfindung die Desoxydation während der Entstehung der Legierungen oder während des Einschmelzens dauernd durch eine stark reduzierende Schlacke bewirkt werden, deren   Reduktionsvermögen   durch Zusätze wieder hergestellt werden kann. 



   Das Verfahren ist insbesondere anwendbar auf Legierungen des Kupfers und kommt hervorragend zur Geltung beim Arbeiten mit dem elektrischen Ofen. 



   Als Reduktionsmittel ist z. B. eine aus Alkalimanganosilikaten bestehende Schlacke geeignet, deren Mangangehalt je nach der verlangten Wirksamkeit bis zu   40"vlO   betragen kann. Das   Reduktionsvermögen   wird während des Einschmelzens oder in den Pausen durch Zusatz   von Metallspänen,   Kohle, Cyankalium, Wasserglas, Borax oder dgl. auf der erforderlichen Höhe erhalten. 



   Das Verfahren hat folgende Vorteile :
1. Die Legierungen können nicht durch einen schädlichen Überschuss des Des-   oxydationsmittel   verunreinigt werden. 



   2. Leicht   ontmischbare   Legierungen, z.   B.   eine hochprozentige Legierung von Kupfer und Blei, können fertig desoxydiert und völlig gleichmässig unmittelbar aus dem elektrischen Ofen gegossen worden. 



   3. Im elektrischen, besonders im Induktionsofen können die Reduktionsphasen aus- schliesslich in die wärmste und auch in die beweglichste Schmelzzone verlegt und kann die grössere Wirksamkeit der Zwischenreaktionen in statu nascendi ausgenützt werden. 



   4. Der Widerstand im Induktionsofen wird erhöht, der Abbrand auf ein Minimum verringert.

  Process for the direct production of deoxidized copper alloys.



   In contrast to the usual method, according to which oxygen-containing metal alloys, which one has somehow obtained, are deoxidized by adding an easily oxidizable element such as phosphorus copper, ferromanganese, ferrosilicon, magnesium, carbon, usually in the pouring ladle According to the invention, the deoxidation during the formation of the alloys or during the melting can be brought about continuously by a strongly reducing slag, the reducing power of which can be restored by additives.



   The process is particularly applicable to copper alloys and comes into its own when working with an electric furnace.



   As a reducing agent, for. B. a slag consisting of alkali manganese silicates is suitable, the manganese content of which can be up to 40 "vlO depending on the required effectiveness. The reducing power is increased during the melting or during the breaks by adding metal chips, coal, potassium cyanide, water glass, borax or the like the required amount.



   The procedure has the following advantages:
1. The alloys cannot be contaminated by a harmful excess of the deoxidizer.



   2. Easily mixable alloys, e.g. B. a high-percentage alloy of copper and lead, can be completely deoxidized and completely evenly poured directly from the electric furnace.



   3. In the electric, especially in the induction furnace, the reduction phases can only be shifted to the warmest and also the most flexible melting zone and the greater effectiveness of the intermediate reactions can be used in statu nascendi.



   4. The resistance in the induction furnace is increased and the burn-up is reduced to a minimum.



   PATENT CLAIMS:
1. A method for the direct production of deoxidized alloys of copper, characterized in that they melt in the electric furnace or in other furnaces
 EMI1.1
 glass, borax or similar acting substances is obtained reactive.
