Es ist bekannt, Metalle nach dem Ausglühen in einer Wassergasatmosphäre abkühlen zu lassen und dabei freiwerdendes Kohlenoxyd mit Luft gemischt zum Erhitzen der Ausglühgefäße zu verwenden. Die Behandlung der glühenden Metalle mit Wassergas soll die beim Glühen entstandene Oxydschicht wieder zu Metall reduzieren.It is known to cool metals after annealing in a water gas atmosphere and using the released carbon dioxide mixed with air to heat the annealing vessels. The treatment of glowing metals with water gas is said to be the oxide layer created during the glowing process reduce back to metal.
Es ist ferner bekannt geworden, beim GlühenIt has also become known when glowing
ίο von Metallen die Retorte mit einem brennbaren Gase zu füllen und an einer Öffnung der Retorte eine Kontrollflamme zu unterhalten, welche die Füllung der Retorte mit Gas anzeigt und durch die Verbrennung eine geringfügige Gasströmung in derselben unterhält. ίο from metals the retort with a flammable To fill gases and to maintain a control flame at an opening of the retort, which indicates the filling of the retort with gas and through the combustion maintains a slight gas flow in the same.
Gemäß der Erfindung wird bei dem Verfahren des Glühens von Metallgegenständen in mit Gas gefüllten Retorten das als Brennstoff für das Glühen benutzte Gas vor seiner Verbrennung durch die Retorte geführt. Dadurch wird zum Füllen der Retorte kein besonderes, sondern das für die Erhitzung benötigte Gasquantum benutzt, und es befindet sich das Gas innerhalb der Retorte in ständiger Strömung. Weiter ergibt sich für das zur Erhitzung verwendete Gas der Vorteil, daß dasselbe der Brennstelle in stark vorgewärmtem Zustande zugeführt wird.According to the invention, in the method of annealing metal objects in retorts filled with gas, the gas used as fuel for the glow before his Burn passed through the retort. This means that there is nothing special about filling the retort, Instead, the gas quantum required for heating is used, and the gas is constantly within the retort Flow. Furthermore, there is the advantage for the gas used for heating that the same of the burning point is strongly preheated States is supplied.
Eine zur Ausführung des Verfahrens geeignete Vorrichtung ist in einer beispielsweisen Ausführungsform auf der Zeichnung dargestellt. An apparatus suitable for carrying out the method is shown in one example Embodiment shown on the drawing.
Das zur Beheizung der Retorte b erforderliche Gas gelangt unter Luftabschluß durch den Kanal α in die Retorte b, die das zu glühende Material enthält. Das Gas tritt von der Retorte durch den Querkanal c in die Kanäle dd', um hinter den kleinen Verbindungskanälen e e' in die Räume f f zu gelangen und von dort mit der durch die Düsen g g' eintretenden Luft in Berührung zu treten und brennend um die Retorte herumzustreichen. Die Abgase entweichen durch die Schornsteinkanäle hh'. The gas required for heating the retort b passes through the channel α in the absence of air into the retort b, which contains the material to be glowed. The gas passes from the retort through the transverse channel c into the channels dd 'to get behind the small connecting channels ee' into the rooms ff and from there comes into contact with the air entering through the nozzles gg 'and burns around the retort prowling around. The exhaust gases escape through the chimney ducts hh '.
Während des Anheizens strömt das Brenngas durch die Retorte und entfernt mit Sicherheit jegliche Luft, so daß die Retorte völlig sauerstoffrei wird. Ohne Schwierigkeiten läßt sich auch beim Erkalten durch andauerndes Durchleiten des Gases durch die Retorte jegliche Oxydation vermeiden.During the preheating process, the fuel gas will flow through the retort and will certainly be removed any air so that the retort is completely free of oxygen. Leaves without difficulty even when cooling down by continuously passing the gas through the retort Avoid oxidation.
