SINTERED PELLET MANUFACTURING METHOD, REDUCED IRON MANUFACTURING METHOD, AND SINTERED PELLET

摘要

A method for manufacturing sintered pellets, which are reduced to become reduced iron by being fed into a reducing furnace Y1, is provided with: a mixing and granulating step for generating pellet grains by mixing iron oxide- and aluminum oxide-containing iron ore with lime; and a firing step for generating sintered pellets by firing the pellet grains. The amount of lime is adjusted in the mixing and granulating step so that the CaO/Al₂O₃ weight ratio in the sintered pellets generated in the firing step is at least 0.5.
