Description

Herstellung einer insbesondere für Lager geeigneten Legierung auf Bronzegrundlage mit hohem Bleigehalt. Ein hoher Bleigehalt ist für Legierungen für Lagerzwecke mit Bronzegrundlage von großem Vorteil. Da aber Blei leicht aussaigert, wenn es in größeren Mengen zugesetzt wird, so ist das Vergießen solcher Legierungen außerordentlich schwierig.Production of an alloy that is particularly suitable for bearings Bronze base with high lead content. A high lead content is for alloys for Storage purposes with a bronze base are of great advantage. But since lead is easily drained, when it is added in large quantities, such alloys are cast extremely difficult.

Es ist bereits bekannt, zur Herstellung antimonfreier Lagermetalle aus Zinn, Zink, Kupfer und mehr als i7 Prozent Blei Vorlegierungen aus Blei, Zinn und Kupfer sowie aus Zink,. Zinn und Kupfer zu verwenden und diese Vorlegierungen in bestimmten Verhältnissen zusammenzuschmelzen.It is already known for the production of antimony-free bearing metals made of tin, zinc, copper and more than 17 percent lead. Master alloys made of lead, tin and copper as well as zinc. Use tin and copper and these master alloys to melt together in certain proportions.

Vorliegende Erfindung betrifft nun ein Verfahren zur Herstellung einer bronzeartigen Legierung mit Bleigehalt bis etwa zu 5o Prozent. Das Verfahren bedeutet eine wesentliche Verbilligung und erleichterte Herstellung der Legierung. Diese läßt sich infolge ihrer Dünnflüssigkeit viel leichter vergießen- als sonstige Legierungen, die neben Kupfer auch viel Blei enthalten. Sie ist wesentlich zäher und hat einen Biegewinkel bis nahezu 9o°. Die Lösung der einzelnen Komponenten ineinander geht rascher vor sich. Neigung zur Bleiausscheidung ist nicht vorhanden, während bei Anwendung von Nickel in geringer Menge neben Blei und Kupfer ein Aussaigern von Blei sehr oft nicht zu verhindern ist.The present invention now relates to a method of making a bronze-like alloy with a lead content of up to about 5o percent. The procedure means a substantial cheaper and easier production of the alloy. These can be cast much easier than other alloys due to their thin liquid, which contain a lot of lead in addition to copper. She is much tougher and has one Bending angle up to almost 9o °. The solution of the individual components goes into each other faster in front of you. There is no tendency to excrete lead while at The use of nickel in small quantities in addition to lead and copper results in a sifting out of Very often lead cannot be prevented.

Das Verfahren besteht in der Anwendung einer Vorlegierung, die noch kein- Blei enthält und aus Phosphorkupfer, Zinn, Zink und Vanadin oder Chrom oder Molybdän oder Wolfram oder Uran bzw. mehreren derselben besteht.The process consists of applying a master alloy that is still does not contain lead and is made up of phosphorus copper, tin, zinc and vanadium or chromium or Molybdenum or tungsten or uranium or several of the same.

Die Hauptlegierung besteht aus einer Schmelze von Kupfer und Blei, in die die Vorlegierung eingeführt wird. Auf diese Weise können leicht gießbare Fertiglegierungen mit bis 50 Prozent Blei erhalten werden, während Zinn und Zink sich ir, Grenzen wie bei gewöhnlicher Bronze bewegen. Der Gehalt an Phosphor und den Metallen Vanadin, Chrom, Molybdän, Wolfram oder Uran soll zusammen nicht weniger als i und nicht mehr als io Prozent betragen.The main alloy consists of a melt of copper and lead into which the master alloy is introduced. In this way, easily cast ready-made alloys with up to 50 percent lead can be obtained, while tin and zinc are within the limits of normal bronze. The content of phosphorus and the metals vanadium, chromium, molybdenum, tungsten or uranium together should not be less than 1 and not more than 10 percent.

Insbesondere hat sich der Zusatz von Mangan sehr bewährt.In particular, the addition of manganese has proven very useful.
