Verfahren zur Vorbereitung von Eisen- und Metallspänen für die Heissbrikettierung.
Wenn man Eisen-, Stahl- oder sonstige Metallspäne zum Zwecke der Heissbriketticrung auf die hiebei zweckmässige hohe Temperatur bringen will, welche bei Eisen und Stahl etwa zwischen 750 und 10000 C liegt, dann besteht die Gefahr, dass die Späne bei der Überführung aus dem Ofen in die Pressform begierig Sauerstoff aufnehmen und dass dadurch sowohl ein erheblicher Verlust an Metall eintritt, als auch die Festigkeit der Briketts leidet, wodurch deren Wert herabgesetzt wird.
Vorliegende Erfindung bezweckt, diese Schwierigkeiten bei der Heissbrikettierung von Spänen zu überwinden, und erreicht den Zweck dadurch, dass die der Brikcttierung zn unterwerfenden Späne während ihrer Erhitzung auf Brikettierungstemperatur durch die besondere-Art der Ausführung dieser Erhitzung so stark mit einer fest an ihnen haftenden reduzierenden Gasschicht umhüllt werden, dass ihnen die Hindurchbewegung durch die Luft bei der Überführung in die Pressform nicht schadet. Diese Einhüllung der Späne in eine Hülle von reduzierendem Gas lässt sich in einfacher Weise erreichen, indem man die Späne in reduzierendem Feuer durch einen Drohrohrofen im Gegenstrom zu den Feuer-

Process for preparing iron and metal shavings for hot briquetting.
If you want to bring iron, steel or other metal chips for the purpose of hot briquetting to the appropriate high temperature, which is between 750 and 10,000 C for iron and steel, then there is a risk that the chips will be transferred from the furnace greedily absorb oxygen into the mold and that both a considerable loss of metal occurs and the strength of the briquettes suffers, which reduces their value.
The present invention aims to overcome these difficulties in the hot briquetting of chips, and achieves the purpose in that the chips which are subjected to briquetting during their heating to the briquetting temperature, due to the special way in which this heating is carried out, so strongly with a reducing which adheres firmly to them Gas layer are encased so that the movement through the air does not damage them when transferring them into the mold. This wrapping of the chips in a shell of reducing gas can be achieved in a simple manner by placing the chips in a reducing fire through a tube furnace in countercurrent to the fire.
EMI1.1
('ase come from the briquette.
A rotary kiln suitable for carrying out the process with a fixed kiln head at the outlet end of the kiln is shown schematically in the drawing.
The stovepipe is labeled A. The fixed, closed furnace head upstream of the furnace outlet end bears the designation B. In the lower wall of the furnace head there is the outlet opening C for the piles in the furnace head
EMI1.2
The chips removed from the furnace are transported by the feeding trolley E to the location of the compacting device, where they are transferred into the mold for the chip briquettes to be produced.
