Description

Verfahren zum Entgasen von Schwermetallschmelzen, insbesondere von Zink oder Zinklegierungen Zusatz zum Patent i33%616 Bekanntlich nehmen Leichtmetalle, wie A'l-uminium oder Magnesium oder ihre Legierungen im Schmelzfluß, besonders im überhitzten Zustand, sehr leicht Wasserstoff auf und halten ihn mehr oder weniger fest. Zur Austreibung des Wasserstoffs aus diesen Leichtmetallschmelzen ist in dem Patent 733616 vorgeschlagen, die Schmelzen mit Mischungen zu behandeln, die neben einem oxydierenden Stoff, wie Nitrate, Nitrite, Sulfate, Persulfate, Schwermetalloxyde, Chlorate oder Perchlorate, noch ein festes Halogenid des Kohlenstoffs, z. B. Hexachloräthan oder Hexachlorbenzol, enthalten.Process for degassing heavy metal melts, in particular of Zinc or zinc alloys Addition to patent i33% 616 It is well known that light metals, like aluminum or magnesium or their alloys in the melt flow, especially in the overheated condition, hydrogen very easily and hold it more or less fixed. To expel the hydrogen from these light metal melts is in the Patent 733616 suggested treating the melts with mixtures that in addition to an oxidizing substance such as nitrates, nitrites, sulfates, persulfates, heavy metal oxides, Chlorates or perchlorates, nor a solid halide of carbon, e.g. B. hexachloroethane or hexachlorobenzene.

Es hat sich nun gezeigt, daß .die in dem Patent 733616 genannten Mittel auch zum Entgasen von Schwermetall.'schmelzen, insbesondere Zii#,I<schmelzen oder solchen aus Zinklegierungen, die ebenfalls sehr zur Wasserstoffaufnahme neigen, geeignet sind. Auch hierbei kann die Zugabe der sauerstoffabgebenden Stoffe und der Halogenide gemeinsam oder nacheinander vorgenommen werden, wobei in gleicher Weise wie in dem Patent 733616 die Oxydationsmittel den in der Schmelze vorhandenen Wasserstoff zu Wasserdampf oxydieren, .der dann durch die leichtverdampfenden Halogenide ausgespült wird.It has now been shown that the means mentioned in patent 733616 also for degassing heavy metal. 'melts, in particular Zii #, I <melt or those made of zinc alloys, which also have a strong tendency to absorb hydrogen, are suitable. Here too, the addition of the oxygen-releasing substances and the halides can be carried out together or in succession, with the same As in the 733616 patent, the oxidizing agents are those present in the melt Oxidize hydrogen to water vapor, then through the easily evaporating halides is rinsed out.
