Abstract
Le procédé de réduction de minerais de fer en vue de fabriquer de l'éponge de fer consiste à déposer une charge de minerai de fer sur une grille et à déplacer ladite grille afin de faire passer ladite charge dans au moins 3 zones de traitement distinctes. Dans une ou plusieurs zones, d'une part on amène des gaz, appelés gaz entrants, incluant un agent réducteur carboné gazeux chaud, et on force lesdits gaz entrants à passer au travers du minerai sis sur la grille, et d'autre part on capte les gaz résultant dudit passage forcé précité, appelés gaz sortants. Le passage des gaz entrants a pour effet qu'on porte ledit minerai à une température comprise entre 850 ·C et 1300 ·C; on garde alors ladite charge à cette température jusqu'à obtenir un taux de métallisation du minerai de fer présent compris entre 60 % et 100 %. La charge déposée sur la grille est composée soit de minerai de fer calibré entre 5 mm et 40 mm, soit de boulettes de minerai de fer d'un diamètre compris entre 5 mm et 20 mm, soit de granules de minerai de fer de calibre compris entre 2 mm à 10 mm, et l'épaisseur de la couche déposée est comprise entre 150 mm et 600 mm. Le flux des gaz entrants, au travers de la charge déposée sur la grille, est dirigé de haut en bas et en général obtenu par la création en dessous de la grille d'une dépression comprise entre 500 et 2000 mm de CE (CE = Colonne d'Eau). Le flux des gaz entrants forcé au travers de la charge dans au moins une zone de traitement est constitué au moins partiellement par du gaz sortant capté sous la grille, ledit gaz sortant capté sous la grille ayant subi au moins un traitement tel qu'un lavage, une désulfuration, un séchage, un dépoussiérage, un réchauffage ou une décarbonatation.
