Description

Verfahren zur Beheizung eines Drehofens zwecks Herstellung von Schmelzen. Gegenstand vorliegender Erfindung betrifft ein besonderes Verfahren zum Beheizen von Drehöfen zwecks Herstellung von Schmelzen aller Art. Das Wesen der Erfindung soll darin bestehen, daß die Beheizung des Drehofens außer mit Kohlenstaub oder einem ähnlichen Brennstoff mit Hilfe des elektrischen Stromes erfolgt, wobei die Zuführungsdüse für das Brennmittel und die Elektroden von der Stirnseite der am Ende des Ofens angeordneten Schmelzzone eingeführt wird. Das Wesentliche dieses kombieierten Heizverfahrens ist darin zu erblicken, daß die Staubfeuerung in kontinuierlicher Weise das betreffende Material zum Schmelzen bringt. Daß jedoch dieses Material in dem Zustand der Schmelze erhalten bleibt, wird lediglich durch den elektrischen Strom bedingt, und zwar durch kurze entsprechende Stromstöße. Die Staubfeuerung und die elektrische Beheizung haben also zwei ganz verschiedene Aufgaben zu lösen. Von der Staubflamme wird auf die Schmelze selbst Wärme nicht abgegeben. Vielmehr wird mit Hilfe der Staubflamme lediglich eine Schmelze erzielt und mit Hilfe des ..lektrischen Stromes die Schmelze erhalten. Abgesehen davon kann mit Hilfe des elektrischen Stromes äuch eine Überheizung der Schmelze herbeigeführt werden. Gemäß der Erfindung sollen bei dem elektrischen Schmelzverfahren nur diejenigen Elektroden unter Strom stehen, die in die Masse eintauchen, was in einfachster Weise und durch der Technik geläufige Arbeitsmittel, wie entsprechende Schaltsegmente o. dgl., erreicht werden kann.Process for heating a rotary furnace for the production of melts. The present invention relates to a particular method of heating of rotary kilns for the production of all kinds of melts. The essence of the invention should be that the heating of the rotary kiln except with coal dust or a similar fuel takes place with the help of electric current, the Feed nozzle for the fuel and the electrodes from the face of the am The melting zone located at the end of the furnace is introduced. The essence of this combed The heating process can be seen in the fact that the dust firing melts the material in question in a continuous manner. But that this material is retained in the state of the melt is only due to the electric current caused by short corresponding current surges. the Dust firing and electrical heating therefore have two completely different tasks to solve. The dust flame does not give off any heat to the melt itself. Rather, only a melt is achieved with the help of the dust flame and with With the help of the ... electrical current, the melt can be maintained. Apart from that, you can use The electric current also causes the melt to overheat will. According to the invention, in the electric melting process, only those Electrodes are live, which are immersed in the mass, what in the simplest way and working equipment familiar from the technology, such as corresponding switching segments o. The like. Can be achieved.

Zur Ausübung des Verfahrens kommt erfahrungsgemäß ein Drehofen in Betracht, an dessen Auslaufseite die eigentliche Schmelzzone angeordnet ist. Diese Schmelzzone kann kugelartig ausgebildet oder auch kugelartig erweitert sein. An der tiefsten Stelle dieser kugelartigen Erweiterung kann ein Stichloch zum Ablauf der Schmelze angeordnet werden. Dieses Verfahren kann mit besonderem Vorteil dort angewendet werden, wo es sich darum handelt, die Schmelze einem Reduktionsprozeß zu unterwerfen, da die elektrische Heizung eine Reduktion der Schmelze bewirkt.Experience has shown that a rotary kiln is used to carry out the process Consider on the outlet side of which the actual melting zone is arranged. These Melting zone can be designed spherically or expanded spherically. At The deepest point of this spherical extension can be a needle hole to drain the melt are arranged. This procedure can be of particular advantage there be used where it is a matter of the melt in a reduction process to subject, as the electrical heating causes a reduction in the melt.
