Description

Verfahren zur Herstellung von Bleilegierungen. Bei der Herstellung von Legierungen des Bleies mit leicht zerfallenden Metallen, wie Kalzium, Natrium, Barium, Strontium, können durch Oxydation Verluste an diesen Metallen entstehen. Auch können sich bei Erstarren und nach dem Erstarren Oxydschichten auf dem Metall bilden, so daß dieses ein unscheinbares Aussehen erhält.Process for the production of lead alloys. In the preparation of of alloys of lead with easily decomposing metals such as calcium, sodium, Barium and strontium can cause losses in these metals through oxidation. Oxide layers can also form on the metal during solidification and after solidification form, so that this gets an inconspicuous appearance.

Diese Übelstände werden gemäß vorliegender Erfindung dadurch vermieden, daß man bei der Herstellung der Legierung einen Zusatz von Aluminium gibt. Das Aluminium legiert sich nicht mit Blei und legiert sich in der Bleilegierung nur schwer mit den anwesenden anderen Metallen, mit denen es an sich Legierungen bildet. Infolgedessen steigt das Aluminium, sofern man einen genügend großen Zusatz gibt, an die Oberfläche des Schmelz-Bades, bildet dort eine dünne Haut und schützt so die in dem Barunterliegenden Schmelzbad befindlichen Metalle vor Oxydation. Bemißt man den Zusatz von Aluminium genügend groß, so wird ein entsprechender Teil sich auch mit den in dem Blei befindlichen anderen Metallen legieren. Diese legierte Aluminiummenge schützt dann in der erstarrten Legierung die leicht zerfallenden Metalle vor der Oxydation.According to the present invention, these inconveniences are avoided by that there is an addition of aluminum in the manufacture of the alloy. The aluminum does not alloy itself with lead and alloy itself with difficulty in the lead alloy the other metals present with which it forms alloys. Consequently the aluminum rises to the surface if a sufficiently large amount is added of the enamel bath, forms a thin skin there and thus protects those lying below in the bar Metals in the weld pool from oxidation. If you measure the addition of aluminum sufficiently large, a corresponding part will also be with those in the lead alloy with other metals. This amount of alloyed aluminum then protects the solidified Alloy the easily decomposing metals before oxidation.

Der Zusatz von Aluminium empfiehlt sich natürlich auch beim Umschmelzen von Bleilegierungen, welche leicht zerfallende Metalle enthalten.The addition of aluminum is of course also recommended for remelting of lead alloys, which contain easily decomposing metals.

Die gemäß vorliegender Erfindung zuzusetzende Aluminiummenge kann äußerst gering gehalten werden. Beispielsweise hat sich bei einem Zusatz von o,o5 Prozent bereits eine sehr günstige Wirkung feststellen lassen.The amount of aluminum to be added in the present invention can be can be kept extremely low. For example, when adding o, o5 Percent already show a very beneficial effect.
