Abstract

Die Erfindung betrifft ein Verfahren zum Recycling von Abfällen, die in einem Stahlwerk anfallen. Erfindungsgemäß werden aus mehreren Abfallstoffen Briketts erstellt, wobei ein Anteil an Eisenoxid in den Briketts zumindest 35 Gewichtsprozent beträgt, wonach die Briketts erwärmt und das Eisenoxid zumindest teilweise reduziert wird. Des Weiteren umfasst die Erfindung eine Vorrichtung zur Durchführung eines solchen Verfahrens.The invention relates to a method for recycling waste that occurs in a steelworks. According to the invention, briquettes are created from several waste materials, a proportion of iron oxide in the briquettes being at least 35 percent by weight, after which the briquettes are heated and the iron oxide is at least partially reduced. The invention also comprises a device for carrying out such a method.
