Verfahren zum Brennen von ohne Bindemittel hergestellten Erzbriketts.
Für die Brikettierung von feinen Eisenerzen hat sich bisher die Herstellung von Briketts ohne Bindemittel und nachheriges Brennen dieser Briketts um vorteilhaftesten erwiesen, weil einerseits auf diesem Wege heute allen Anforderungen für die spätere Verhüttung entsprechende Briketts hergestellt werden, andererseits keine den Eisengehalt herunterdrückende oder die nachherige Verhüttung erschwerende Bindemittel zugesetzt werden. Immerhin hat diese Art der Brikettierung sich bis jetzt nur für sehr reiche Konzentrate eingeführt, weil die Kosten derselben noch zu hoch scrod.
Vorliegende Erfindung bezweckt nun, die Kosten der Brikettierung von Feiner n, insbesondere Eisenerzen, herunterzudrücken, und kennzeichnet sich dieselbe im wesentlichen wie folgt :
Das zu brikettierende Feinerz wird in bekannter Weise ohne Anwendung eines Bindemittels auf geeigneten Pressen in Briketts geformt, die dann in einen Kanal eingesetzt werden, in welchem sie bis zur notwendigen Sinterung gebrannt werden.
Die zur Sinterung notwendige Wärme wird gemäss der Erfindung auf folgende Weise erreicht :

ein entsprechender Raum verbleibt, welcher mit Koksgrus oder einem anderen verwendbaren billigen Brennmaterial angefüllt wird. An dem einen Ende des Kanals wird dann nach beendoter Beschickung des Kanals eine geringe Menge glühender Kohle aufgegeben und danach Luft unter entsprechendem Druck durch diese glühende Kohle in den mit Briketts und Brennmaterial gefiillten Kanal ongcblasen. Durch Regulierung des Druckt's der Gebläseluft hat man es in der Hand. die Sinterung schneller oder langsamer verlaufen zu lassen.

Method of burning ore briquettes made without a binder.
For the briquetting of fine iron ores, the production of briquettes without binders and subsequent firing of these briquettes has proven to be the most advantageous, because on the one hand this is the way to produce briquettes that meet all requirements for later smelting, on the other hand, no briquettes that lower the iron content or subsequent smelting aggravating binders are added. After all, this type of briquetting has so far only been introduced for very rich concentrates because the costs of the same are still too high.
The present invention now aims to reduce the cost of briquetting of fines, in particular iron ores, and is essentially characterized as follows:
The fine ore to be briquetted is formed into briquettes in a known manner without the use of a binder on suitable presses, which are then inserted into a channel in which they are burned until the necessary sintering.
The heat required for sintering is achieved according to the invention in the following way:
EMI1.1
A corresponding space remains, which is filled with coke breeze or another cheap fuel that can be used. At one end of the canal, after the end of the loading of the canal, a small amount of glowing coal is applied and air is then blown under the appropriate pressure through this glowing coal into the canal filled with briquettes and fuel. By regulating the pressure of the fan air you have it in your hand. to let the sintering proceed faster or slower.
Likewise, the amount of the in the spaces between the briquettes is determined
EMI1.2
Sieve given. whereby the ascben residue of the fuel precipitates.
