SELF-FLUXING PELLETS FOR BLAST FURNACES AND METHOD FOR PRODUCTION THEREOF

摘要

Disclosed is a self-fluxing pellet for blast furnace, which is characterized by having a CaO/SiOmass ratio of not I less than 0.8 and an MgO/SiOmass ratio of not less than 0.4. This self-fluxing pellet for blast furnace is further characterized by I having such a particle size distribution wherein the average particle size is 10-13 mm, those having a particle size of not less than 4 mm but less than 8 mm are in an amount of 6 % by mass or less, and those having a particle size of not less than 15 mm but less than 20 mm are in an amount of 7 % by mass or less.
