摘要
PROBLEM TO BE SOLVED: To provide a method for operating a blast furnace using a non-fired agglomerated ore, capable of realizing a stable operation of the blast furnace by preventing deterioration in permeability when using the non-fired agglomerated ore in the blast furnace.;SOLUTION: The method for operating the blast furnace using the non-fired agglomerated ore comprises a step of charging the non-fired agglomerated ore into a peripheral part of the furnace at a radius location corresponding to 0.7-1.0 by a non-dimensional radius when using the non-fired agglomerated ore 1 as a raw material for iron manufacture in the bell-less blast furnace, provided that the non-fired agglomerated ore 1 is obtained by agglomerating an iron oxide raw material with an inorganic binder such as cement 4.;COPYRIGHT: (C)2009,JPO&INPIT
