PROCESS AND DEVICE FOR PRODUCING COKE

The process for producing coke, in particular furnace coke, uses considerable amounts of lean or relatively lean caking coal which is submitted to compaction so as to obtain pressed substances; these pressed substances are used on their own or mixed with additional material as charge in a coke furnace for the coking. The coal (A) is submitted during compaction to forces acting upon different directions (D, T) in order to create shearing and/or rotating stress. This causes the mutual fixing of the coal particles thus giving highly resistant pressed material with a high degree of conservation. During compaction, heat can be brought to the material. A device for application of this process comprises a matrix and an element which makes the material pass through the channels of the matrix. These channels have different diameters and can also have different lengths. Le procede pour la fabrication de coke, en particulier de coke metallurgique, utilise des quantites considerables de houille d'agglutination faible ou relativement faible, qui est soumise a un compactage afin d'obtenir des corps presses; ces corps presses sont utilises seuls ou melanges avec du materiau supplementaire comme charge dans un four a coke en vue de la cokefaction. La houille (A) est soumise pendant le compactage a des forces agissant selon differentes directions (D, T) pour la creation d'efforts de cisaillement et/ou d'efforts de torsion. Ceci provoque une fixation mutuelle des particules de charbon pour obtenir des corps presses de haute resistance et ayant un bon degre de conservation. Pendant le compactage on peut amener de la chaleur au materiau. Un dispositif pour la mise en oeuvre du procede comprend une matrice et un organe qui fait passer le materiau a travers les canaux de la matrice. Ces canaux ont des diametres differents et peuvent, en outre, avoir des longueurs differentes.
