Patent

CA 2410021

The invention is a method of making metallized iron agglomerates by combining iron/steel particles and a reductant material with a cellulose fiber binder material, compacting the combination to form a solid agglomerate, and reducing the iron portions of the agglomerate in a direct reduction furnace (22). The cellulose fiber binder material provides an agglomerate having improved strength and lower overall cost than comparable agglomerates using binders known in the art.

L'invention concerne un procédé de fabrication d'agglomérats de fer métallisés par la combinaison de particules de fer/acier et d'un matériau réducteur avec un matériau liant de fibre de cellulose. Ensuite, il faut compacter la combinaison en vue de former un agglomérat solide et de réduire les parties de fer présentes dans l'agglomérat dans un four à réduction directe (22). Le matériau liant de fibre de cellulose fournit un agglomérat dont la résistance est renforcée et le coût global réduit, par rapport aux autres agglomérats employant des liants, déjà connus dans l'art antérieur.
