Description
Verfahren zur Entfernung von Aluminium und Eisen aus Kupferlegierungen Gegenstand der Erfindung ist ein Verfahren zur Entfernung von Aluminium und Eisen aus Kupferlegierungen, insbesondere aus Kupfer-Zinn- und Kupfer-Zink-Legierungen, bei dem der Aluminium- und Eisengehalt der angewendeten Werkstoffe in einfacher und bequemer Weise beseitigt wird. Diese Metalle bewirken, daß die aus den Kupferlegierungen hergestellten Gußstücke porös und wenig haltbar sind.Process for removing aluminum and iron from copper alloys The invention relates to a method for removing aluminum and iron from copper alloys, in particular from copper-tin and copper-zinc alloys, in which the aluminum and iron content of the materials used in a simple and conveniently eliminated. These metals cause the copper alloys castings produced are porous and not very durable.
Zur Entfernung von Aluminium und Eisen wird nach der Erfindung der Schmelze Natriumpyrosulfat in Mischung mit anderen an sich bekannten Flußmitteln, und zwar Flußspat, Kieselsäure, Kupferoxyd und koh-' lensaurem Kalk, zugesetzt.To remove aluminum and iron, according to the invention, the Melt sodium pyrosulphate mixed with other known fluxes, fluorspar, silicic acid, copper oxide and carbonate of lime were added.
Als besonders gut geeignete Mischung wurde die folgende fertiggestellt:
Ausführungsbeispiel 5o kg Kupfer, 3 5 kg Zink und i 5 kg Altmessing werden in einem Tiegel eingeschmolzen. In das zum Gießen fertige Metallbad wird i kg der obenerwähnten Mischung eingerührt: Dadurch werden Aluminium und Eisen in de Schlacke übergeführt.Embodiment 50 kg copper, 35 kg zinc and 15 kg old brass are melted in a crucible. In the metal bath ready for casting i kg of the above-mentioned mixture stirred in: this causes aluminum and iron to be mixed in de slag transferred.
Dieses Reinigungsverfahren kann bei Metallgüssen, wie Rotguß, Bronze-, Neusilber und Kupferguß, angewandt werden.This cleaning process can be used for metal castings such as gunmetal, bronze, German silver and cast copper can be used.
