Description
Legierung. Die Herstellung einer Legierung von Nickel oder Kobalt, oder von Nickel und Kobalt mit Blei oder mit Bleilegierungen begegnete bisher großen Schwierigkeiten, die in dem Unterschied der Schmelzpunkte von Nickel oder Kobalt oder von Nickel-Kobalt-Legierungen einerseits und von Blei oder Bleilegierungen anderseits begründet sind. Eine rasche und vor allem sichere Vereinigung der genannten Metalle erfolgt infolge des hohen Schmelzpunktes von Nickel bzw. Kobalt oder von Nickel-Kobalt-Legierungen erst bei sehr hohen Temperaturen, so daß wesentliche Bleiverluste infolge von Verdampfung und starker Krätzebildung eintreten. Hierbei wird die Legierung auch durch starke Krätzeeinschlüsse verunreinigt.Alloy. The manufacture of an alloy of nickel or cobalt, or of nickel and cobalt with lead or with lead alloys encountered so far great Difficulty arising in the difference in the melting points of nickel or cobalt or from nickel-cobalt alloys on the one hand and from lead or lead alloys on the other hand are justified. A quick and, above all, safe union of the above Metals occurs as a result of the high melting point of nickel or cobalt or of Nickel-cobalt alloys only at very high temperatures, so that significant lead losses occur as a result of evaporation and strong dross formation. This is where the alloy also contaminated by strong dross inclusions.
Nach vorliegender Erfindung, welche auf einfachem Wege rasch. und sicher zum Ziele führt, werden die geschilderten Übelstände vollkommen vermieden, da es möglich ist, bei verhältnismäßig niedriger Temperatur zu legieren, und zwar dadurch, daß man von einer Legierung bzw. Verbindung von Nickel oder Kobalt oder von beiden mit Phosphor ausgeht.According to the present invention, which quickly and easily. and leads safely to the goal, the evils described are completely avoided, because it is possible to alloy at a relatively low temperature, namely in that one of an alloy or compound of nickel or cobalt or both start with phosphorus.
Eine Legierung bzw. Verbindung von Nickel mit beispielsweise i i Prozent Phosphor schmilzt bereits bei etwa 88o° C, eine solche von Kobalt mit 16,6 Prozent Phosphor bei io22° C.An alloy or compound of nickel with, for example, i i percent Phosphorus melts at around 88o ° C, cobalt at 16.6 percent Phosphorus at 1022 ° C.
Soll nun eine Legierung von Nickel oder Kobalt oder von beiden mit Blei oder Bleilegierungen hergestellt werden, so genügt es, die Nickel- (Kobalt-)Phosphor-Legierung, die nach bekannter Methode erzeugt wird, zu schmelzen und in dünnem Strahl unter Umrühren in das wenig über den Schmelzpunkt erhitzte Blei bzw. die Bleilegierung einzugießen, wobei eine glatte Vereinigung erfolgt. Der in Form der genannten Phosphorlegierung angewandte Phosphor vereinigt sieh mit den in der geschmolzenen Legierung als Verunreinigung vorhandenen bzw. beim Einschmelzen gebildeten Metalloxyden und reduziert dieselben, während er selbst in flüchtiges Oxyd übergeht. Das Verfahren hat also vor den bisher angewandten den Vorzug, das Metallbad zu reinigen, also zu desoxydieren und daher ein besseres Endprodukt zu liefern, als es bisher erhalten wurde.Should now be an alloy of nickel or cobalt or both with Lead or lead alloys are produced, it is sufficient to use the nickel (cobalt) phosphorus alloy, which is produced according to a known method, to melt and in a thin stream under Stir in the lead or lead alloy, which has been heated a little above the melting point pour in, making a smooth union. The one in the form of the aforementioned phosphorus alloy applied phosphorus is combined with that in the molten alloy as an impurity existing or formed metal oxides during melting and reduces them, while it turns into volatile oxide itself. So the procedure has been ahead of so far applied the advantage of cleaning the metal bath, i.e. deoxidizing it and therefore to deliver a better end product than has previously been obtained.
