PROCESS AND EQUIPMENT FOR BLAST FURNACE CONVERSION TO THE SELF-REDUCTION MODE
The invention converts existing blast furnaces (1) from gas/solid reduction to self-reduction (2), reducing the process time from 8 hours to 30 minutes. Sinter, pellets or mineral (17) are replaced by self-reducing agglomerates (30), and coke (16) by mineral-coal agglomerates and/or biomass agglomer...

| description | The invention converts existing blast furnaces (1) from gas/solid reduction to self-reduction (2), reducing the process time from 8 hours to 30 minutes. Sinter, pellets or mineral (17) are replaced by self-reducing agglomerates (30), and coke (16) by mineral-coal agglomerates and/or biomass agglomerates (29). Inserting two concentric cylindrical or polyhedral elements (25) and (26) into the blast furnaces forms two isolated columns for loading the agglomerates (29) and (30), which are positioned just above the plane of the tuyères (12). The reduction and fusion zone (32) formed by the flame (20), which is regulated to generate high power, makes it possible to reduce the height of the active column of the blast furnaces (1) and the charge residence time. The agglomerates (29) are loaded between the casing (11) and the element (25), and the agglomerates (30) are loaded between the element (25) and the element (26).
L'invention permet de convertir les hauts fourneaux actuels (1) de la réduction gaz/solide en auto-réduction (2), réduisant ainsi le temps de traitement de 8 heures à 30 minutes. On remplace les produits frittés, les pellets ou le minerai (17) par des agglomérés auto-réducteurs (30) et le coke (16) par des agglomérés de charbon minéral et/ou de biomasse (29). L'introduction, à l'intérieur des hauts fourneaux de deux éléments concentriques de forme cylindrique ou polyèdre (25) et (26) permet la formation de deux colonnes isolées de charge des agglomérés (29) et (30) qui se trouvent légèrement au-dessus du plan des tuyères (12), dans la zone de réduction et de fusion (32) formée par la flamme (20), régulée pour produire une haute énergie, permettant de réduire la hauteur de la colonne active des hauts fourneaux (1) et le temps de séjour de la charge. Les agglomérés (29) sont chargés entre l'enveloppe (11) et l'élément (25), les agglomérés (30) étant chargés entre l'élément (25) et l'élément (26).
