Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung von Metallpulver aus dergleichen Schmelzen.The invention relates to a method and an apparatus for producing Metal powder from the same melts.

Um einen hohen Anteil an Pulverteilchen mit geringem Komdurchmesser und eine hohe Schüttdichte des Metallpulvers zu erstellen, ist erfindungsgemäß vorgesehen, daß der aus dem Schmelzendüsenkörper (D) im wesentlichen vertikal austretende Schmelzenstrom (S) durch mindestens drei Gasstrahlen (1,2,3) mit jeweils verschiedenen Richtungen beaufschlagt wird, wobei die Gasstrahlen in der Wirkfolge jeweils auf den eingebrachten Schmelzenstrom S auf den durch den jeweils vorgeordneten Gasstrahl in der Richtung eingestellten und geformten Schmelzenstrom (FS) mit einem Winkel zwischen 5° und 170° ausgerichtet sind.

Figure 00000001
In order to create a high proportion of powder particles with a small grain diameter and a high bulk density of the metal powder, the invention provides that the melt stream (S) emerging essentially vertically from the melt nozzle body (D) by at least three gas jets (1,2,3) In each case, different directions are applied, the gas jets being aligned in the sequence of action in each case to the melt stream S introduced to the melt stream (FS) set and shaped by the respective upstream gas jet at an angle between 5 ° and 170 °.
