PATENTAMT.PATENT OFFICE.
Gegenstand der Erfindung ist eine weitere Ausbildung des Verfahrens zur Herstellung eines Systems von Blei-Zink-Legierungen mit Zinn-, Kupfer- und Antimonzusatz und beliebig wählbarem Bleigehalt von 17 Prozent und mehr.The invention relates to a further embodiment of the method for production a system of lead-zinc alloys with added tin, copper and antimony and any Selectable lead content of 17 percent and more.
Die Neuerung besteht zunächst darin, daß zur Herstellung nicht reines Zinn, sondern Zinn ausschließlich in gebundener Form zugegeben wird, d. h. in einer hochprozentigen Zinnlegierung aus 84 bis 80 Teilen Zinn, 11 bis 12 Teilen Antimon und 5 bis 8 Teilen Kupfer, ferner, daß einer mehrfachen Stoffgruppe F1 aus Blei und der genannten Zinnlegierung Teile einer anderen, höherschmelzenden, in sich gemischten Stoffgruppe F2 aus Zink, Kupfer und der erwähnten Zinnlegierung beigegeben werden, um durch diesen besonderen metallurgischen Vorgang den Erstarrungspunkt der ersteren absichtlich höher zu legen, als er ohne diesen Zusatz naturgemäß liegen kann, zum Zweck der Regelung der Erstarrung der fertigen Legierung aus den Hauptstoffen Blei und Zink neben den anderen Stoffen Antimon, Zinn und Kupfer, wodurch ein Abscheiden des Bleis infolge höheren spezifischen Gewichts unter allen Umständen vermieden bleibt.The innovation consists in the fact that for the production not pure tin, but tin is added exclusively in bound form, ie in a high-percentage tin alloy of 84 to 80 parts of tin, 11 to 12 parts of antimony and 5 to 8 parts of copper, furthermore that one multiple substance group F 1 made of lead and the tin alloy mentioned, parts of a different, higher melting, mixed substance group F 2 made of zinc, copper and the tin alloy mentioned are added in order to deliberately raise the solidification point of the former higher than it is through this special metallurgical process can naturally lie without this addition, for the purpose of regulating the solidification of the finished alloy from the main substances lead and zinc in addition to the other substances antimony, tin and copper, whereby a deposition of the lead due to the higher specific weight is avoided under all circumstances.
Die Vorlegierung F2 wird zusammengesetzt aus 80 bis 70 Teilen Zink, 18 bis 24 Teilen Zinnlegierung und 2 bis 6 Teilen Kupfer und die Vorlegierung F1 aus 65 bis 55 Teilen Blei, 7 bis 12 Teilen F2 und 23 bis 33 Teilen Zinnlegierung, je nach der Reinheit und Zusammensetzung der verwendeten Materialien. Die Herstellung der Endlegierung geschieht dann durch Zusammenschmelzen von Bruchteilen der Stoffgruppen F1 und F2 nach Maßgabe der zu erzielenden Kugeldruckhärte. In Betracht kommen als Gewichtsverhältnisse der beiden Vorlegierungen sämtliche in den Zusammensetzungen : 20 F1 + 80 F2 bis 80 F1 + F2 liegenden Werte.The master alloy F 2 is composed of 80 to 70 parts of zinc, 18 to 24 parts of tin alloy and 2 to 6 parts of copper and the master alloy F 1 of 65 to 55 parts of lead, 7 to 12 parts of F 2 and 23 to 33 parts of tin alloy, each according to the purity and composition of the materials used. The final alloy is then produced by melting together fractions of the substance groups F 1 and F 2 in accordance with the ball indentation hardness to be achieved. All values in the compositions: 20 F 1 + 80 F 2 to 80 F 1 + F 2 come into consideration as weight ratios of the two master alloys.
