Title (EN) A METHOD FOR THE MANUFACTURE OF AN ADDITIVE MATERIAL FOR THE PRODUCTION OF CRUDE IRON
(FR) PROCEDE DE FABRICATION D"UN ADDITIF POUR LA PRODUCTION DE FER BRUT
Abstract:
(EN) A method for the manufacture an additive material for the production of crude iron which comprises charging an iron sulphidic material to a furnace space together with oxygen and a silicate-containing material in relative proportions such that it is possible to obtain an iron silicate melt containing 60-90% by weight iron, calculated as iron (11) oxide when melting. The melt is granulated or permitted to solidify and then crushed to pieces of a size suitable to charge to a furnace unit for the production of crude iron.
(FR) Procede de fabrication d"un additif pour la production de fer brut consistant a charger dans un four un materiau a base de sulfure de fer avec de l"oxygene et un materiau contenant un silicate dans des proportions telles qu"il est possible d"obtenir un produit de fusion fer-silicate contenant 60 a 90% en poids de fer, calcule sous forme d"oxyde de fer (II) a la fusion. On grenaille le produit de fusion ou on le laisse se solidifier et on le broye en particules d"une taille qui se prete au chargement d"un four pour la production de fer brut.
