KLASSEGREAT
Das Verfahren bezweckt die Herstellung eines metallreinen Bronzepulvers durch Zerstäubung von flüssigem Metall mittels sauerstofffreier Gase in einer sauerstofffreien Kammer. The purpose of the process is to produce a metal-pure bronze powder by atomization of liquid metal by means of oxygen-free gases in an oxygen-free chamber.
Bekannt, ist das Verfahren, geschmolzenes Metall mittels gespannten Dampfes, gepreßter Luft oder unter Druck stehenden Gases zu zerstäuben. Die Zerstäubungsvorgänge nach diesem Verfahren gehen aber in einem gewöhnlichen Arbeitsraume, also in freier Luft vor sich, wobei das noch glühende Metallpulver durch die Einwirkung von Sauerstoff die ursprüngliche Metallfarbe und den Metallglanz verliert und daher als Bronzepulver nicht verwendet werden kann.The method is known, molten metal by means of compressed steam, compressed air or under pressure To atomize gas. The atomization processes according to this method go into an ordinary workspace, i.e. in the open air in front of you, although that still red-hot metal powder by the action of oxygen the original metal color and loses the metallic luster and therefore cannot be used as bronze powder.
Bekannt ist auch das Verfahren, mittels Wasser und Dampf das flüssige Metall in so einer gegen die Luft abgeschlossenen Kammer zu zerstäuben.Also known is the process by means of water and steam in the liquid metal to atomize such a chamber closed off from the air.
Die vorliegende Neuerung dagegen besteht in dem Verfahren, die Zerstäubung des flüssigen Metalles mittels Gase, welche keinen Sauerstoff enthalten, wie Wasserstoff- as gas oder Stickstoff, in einer Kammer vorzunehmen, welche mit einem gleichen sauerstofffreien Gas gefüllt ist, zu dem Zweck, eine Oxydierung des Zerstäubungsproduktes zu verhindern.The present innovation, however, consists in the process, the atomization of the liquid metal by means of gases that do not contain oxygen, such as hydrogen as gas or nitrogen in a chamber which is filled with an identical oxygen-free gas for the purpose of to prevent oxidation of the atomized product.
Das Metall fließt hierbei von einem höher liegenden Bade zu.The metal flows in from a bath located higher up.
Das unter Druck stehende Gas ,wird durch Röhren in die Kammer geführt und strömt durch Streudüsen gegen den Metallfluß.The pressurized gas is fed into the chamber through tubes and flows by sprinkling nozzles against the flow of metal.
JDie Zerstäubungskammer kann innerhalb eines Gasbehälters angeordnet sein, welcher auch als Druckbehälter dienen kann.JThe atomization chamber can be arranged within a gas container, which can also serve as a pressure vessel.
