Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand vorliegender Erfindung ist ein Verfahren zum Zusammenbacken von Erzen mit Kohle und Zuschlägen unter Zuhilfenahme, des elektrischen Stromes, bei welchem gleichzeitig eine teilweise Reduktion der Erze eintritt.The present invention relates to a method for caking ores together with coal and surcharges with the aid of the electric current, with which at the same time a partial reduction of the ores occurs.
Es ist zwar bereits vorgeschlagen worden,While it has already been suggested
die Erze durch starke Erhitzung mittels des elektrischen Stromes zusammenzubacken, jedoch ohne sie zu reduzieren (vergl. z. B. die amerikanische Patentschrift 641552).to bake the ores together by strong heating by means of the electric current, however without reducing it (see, for example, American patent specification 641552).
Das bloße Zusammensintern der Erze ohne Reduktion nach diesem älteren Verfahren kann bei hoher Temperatur mit großer Schnelligkeit ausgeführt werden.The mere sintering of the ores without reduction according to this older process can be carried out at high temperature with great speed.
Das vorliegende Verfahren unterscheidet sich hiervon im wesentlichen dadurch, daß' die Endmasse bereits teilweise reduziert ist, und dieser Erfolg kann nur erreicht werden, wenn die Behandlung eine weniger schnelle ist, um den Erzteilchen Zeit zu geben, den Sauerstoff abzuspalten.-The present method differs from this essentially in that ' the final mass is already partially reduced, and this success can only be achieved if the treatment is a less rapid one, to give the ore particles time, the Split off oxygen.
Der Kernpunkt des vorliegenden Verfahrens besteht also darin, daß zerkleinerte Erze unter Anwendung eines starken elektrischen Stromes in teilweise reduzierte Stücke zusammengebacken werden, und zwar im ununterbrochenen Betrieb.The crux of the present process is that crushed ores under Application of a strong electric current in partially reduced pieces baked together in uninterrupted operation.
Die so erhaltenen Erzstücke können dann leicht und in beliebiger Weise auf Metall verarbeitet werden.The pieces of ore obtained in this way can then easily and in any desired manner on metal are processed.
Bei Ausführung des Verfahrens mischt man das Erz mit Flußmitteln und einem reduzierend wirkenden Stoff, wie z. B. Holzkohle, Koksstaub o. dgl., und zwar vorzugsweise in Verbindung mit einer Flüssigkeit, wie Melasse, Öl ο. dgl.In carrying out the process, the ore is mixed with fluxes and one reducing agent acting substance, such. B. charcoal, coke dust o. The like., Preferably in Connection with a liquid such as molasses, oil ο. like
Alsdann setzt man die gut durchgemischte Masse der Wirkung eines elektrischen Stromes aus, indem man sie in einen sich nach unten stark verjüngenden Schacht bringt, an dessen engster Stelle die Pole einer Stromquelle eingeführt werden, wie z. B. bei dem durch das Patent 138659 geschützten elektrischen Ofen.Then the well mixed mass is put to the effect of an electric current by bringing them into a shaft that tapers sharply downwards, at its The poles of a power source are introduced into the narrowest point, such as B. in the case of the Patent 138659 protected electric furnace.
Je nachdem nun die Stücke des mit den Zuschlägen gemischten Erzes größer oder kleiner sein sollen, macht man den Abstand der beiden Pole größer oder kleiner.Depending on whether the pieces of ore mixed with the aggregates are larger or larger should be smaller, the distance between the two poles is made larger or smaller.
Zwischen den Polen bilden die leitenden Bestandteile der Masse für den Strom eine Brücke und werden, wenn der Strom entsprechend stark ist, derart erhitzt, daß gleichzeitig eine Sinterung und eine teilweise Reduktion der Erze eintritt.The conductive components of the ground for the current form one between the poles Bridge and, if the current is sufficiently strong, heated in such a way that at the same time sintering and partial reduction of the ores occurs.
