Abstract

Provided is a method for manufacturing sintered ore with which product sintered ore wherein reductions in quality are suppressed can be manufactured using sintered feedstock that includes iron ore and dust generated within a steel mill even when the component concentrations thereof vary. The manufacturing method for sintered ore, which is for manufacturing sintered ore by granulating sintered feedstock wherein at least feedstock including iron, feedstock including CaO, and an aggregating material are mixed and sintering the sintered feedstock in a sintering machine, has a measurement step for continuous measurement of at least one component concentration among the feedstock containing iron, sintered feedstock, and granulated sintered feedstock. Using the component concentration measured in the measurement step, at least one of the amount of feedstock containing CaO mixed in, the amount of aggregating material mixed in, the amount of water added, and the rate of progress of a pallet truck for the sintering machine is adjusted.
