Description
Ofen zum Reduzieren von oxydischen Eisenerzen. Zum Reduzieren von oxvdischen Eisenerzen sind Öfen bekannt, bei denen die Erze über eine Reibe von Stufen einem Strom heißer reduzierender Gase entgegengeführt und dabei abwechselnd auf den einzelnen Stufen von der Ofenmitte nach der Ofenwandung und umgekehrt bewegt werden. Die. Eifindung besteht nun darin, daß die Stufen abwechselnd fest und drehbar sind, und daß die festen Stufen zweckmäLÜgerweise mit einem mittleren Kern und die drehbaren Stufen mit dem Außenmantel verbunden sind.Furnace for reducing oxidic iron ores. To reduce Oxvdischen iron ores are known furnaces, in which the ores over a grater from Steps counter to a stream of hot reducing gases and alternate moved on the individual steps from the middle of the furnace to the furnace wall and vice versa will. The. The idea now consists in the fact that the steps are alternately fixed and rotatable are, and that the fixed levels are expediently with a middle core and the rotatable steps are connected to the outer shell.
In der Abbildung ist der neue Ofen in einer Ausführungsform dargestellt.In the figure, the new furnace is shown in one embodiment.
a ist der drehbare Mantel des Ofens, an dem die Herdplatten b befestigt sind; c ist der feststehende Innenkern mit Platten d; e ist der Zufüllrungstrichter der Erze nebst Zuschlägen, gegebenenfalls Kohlen, die durch Öffnungen f in den Ofen geführt werden. Durch Drehung des Mantels und durch die Arbeitswirkung der Zinken g, welche an der Unterseite -jeder Platte befestigt sind, wird die Beschickung stetig von Stufe zu Stufe nach unten geschaufelt, in Gegenstrom zu dem aufsteigenden Reduktionsgas, das durch den Ringkanal !t und die öttnungen i in den Ofen gelangt, der durch die gasdichten Verschlüsse k und k' nach außen hin abgedichtet igt. l' ist der Kühlraum für den heißen Eisenschwamm, worin er zwecks Verhütung einer Reoxydation gekühlt, gegebenenfalls auch gekohlt oder mit Hilfe von Gebläseluft in bekannter Weise geschmolzen wird.a is the rotatable shell of the oven to which the hotplates b are attached; c is the fixed inner core with plates d; e is the feed hopper for the ores together with aggregates, possibly coals, which are fed into the furnace through openings f. G by rotation of the jacket and through the working action of the tines, which are attached to the bottom-each plate, the feed is continuously scooped from stage to stage downward, in counterflow to the rising reducing gas! T by the ring channel and the öttnungen i enters the furnace, which igt sealed to the outside by the gas-tight closures k and k '. l 'is the cooling space for the hot sponge iron, in which it is cooled in order to prevent reoxidation, optionally also carbonized or melted in a known manner with the aid of forced air.
