Method of producing agglomerates |
摘要 |
A method of producing agglomerates from a fine iron ore or the like having a wide particle size distribution. A solid fuel is added to the fine ore and the material is formed into pellets or briquettes of a two-layer structure comprising a core portion and a shell portion having different solid fuel contents, and the pellets or briquettes are charged onto a grate of a travelling grate-type furnace including an updraft drying zone, a downdraft drying zone, an ignition zone and a suction burning zone in such a manner that the charge having a higher solid fuel content forms a grate upper layer portion and the charge having a lower solid fuel content forms a grate lower layer portion, thereby firing the pellets or briquettes by the furnace.
