Verfahren besteht darin, dass Aie erwähnten. armen Heizgase, wie z. B. Generator-, Mischund Hochofengase komprimiert werden, so dass die Möglichkeit geboten ist, aus diesen Gasen eine Stichnamme zu erzeugendie o geleitet werden kann, dass sie in ihrer Gänze mit dem im Ofen befindlichen zu sinternden Material in Berührung kommt, so dass dasselbe sofort auf eine ausserordentlich hohe Temperatur gebracht werden kann, während die von der Stichssammo nicht berührten Teile des Ofens nur von den abziehenden Feuergasen erwärmt, also auf eine wesentlich geringere Temperatur gebracht werden.
Das weiter oben befindliche Material wird daher nur vorgewärmt, nicht aber bis zum Sintern gebracht, wodurch eine Bildung von festen Ansätzen im Ofen bei entsprechend grossem Querschnitt dos rotierenden Ofenrohres ganz ausgeschlossen erscheint und doch genügend Material durchgesetzt werden kann, um einen rentablen Grossbetrieb durchführen zu können.
Die Durchführung des Verfahrens erfolgt in einem rotierenden Ofen sonst bekannter Konstruktion, der jedoch mit oben erwähnter Feuerung ausgestattet ist. In beiliegender Zeichnung ist ein zur Ausführung des Verfahrens geeigneter. Ofen ersichtlich gemacht.

mit Ansicht dos Brenners.
Das zur Sinterung dienende komprimierte Heizgas wird durch die Leitung d, die Verbronnungsluft durch die Leitung c in den Brenner e gedrückt, in welchem die Mischung von Gas und Luft erfolgt und der so gerichtet werden kann, dass die aus demselben austretende Stichflammo auf eine bestimmte Zone des Ofenrohres b trifft und diese sofort so

Ofenrohres durch die abziehenden Fenergase vorgewärmte, noch staubförmige Material sofort zum Sintern gebracht wird, wobei infolge der durch die Drehung des Ofens hervorgerufenen Bewegung des Materials die Staubteile zu Klumpen agglomeriert werden, die am Ende des Ofenrohres bei f aus demselben herausfallen.

Procedure is that Aie mentioned. poor heating gases, such as B. generator, mixed and blast furnace gases are compressed, so that the possibility is offered to generate a cue name from these gases o can be directed so that it comes into contact in its entirety with the material to be sintered in the furnace, so the same thing immediately can be brought to an extraordinarily high temperature, while the parts of the furnace that are not touched by the stab sammo are only heated by the evacuating fire gases, i.e. brought to a significantly lower temperature.
The material above is therefore only preheated, but not brought to sintering, whereby the formation of solid deposits in the furnace with a correspondingly large cross-section of the rotating furnace tube appears to be completely excluded and yet enough material can be passed through to be able to carry out a profitable large-scale operation .
The process is carried out in a rotating furnace of otherwise known construction, which is, however, equipped with the above-mentioned furnace. In the accompanying drawing, a suitable one for carrying out the process is shown. Oven made visible.
EMI2.1
with view of the burner.
The compressed heating gas used for sintering is pressed through line d, and the combustion air through line c into burner e, in which the gas and air are mixed and which can be directed so that the flash flame emitted from the same is directed to a specific zone of the stovepipe b and this immediately so
EMI2.2
Stove pipe is immediately sintered by the extracting Fenergase, still powdery material, whereby due to the movement of the material caused by the rotation of the furnace, the dust particles are agglomerated into lumps, which fall out of the same at the end of the furnace pipe at f.
