into the blast furnace from tuyers located in the lower part of the furnace and hot air burns coke. If a fine iron ore pow-der is loaded in blast furnace, it flies away with hot air and prevents hot gas from flowing through blast furnace. Be-cause of these reasons fine iron ore powders have not been used in blast furnace.
