Abstract (en)
Provided is a method for manufacturing sintered ore with which, even in the case where there is a variation in the component concentrations in iron ore and dust generated in a steel plant, it is possible to manufacture product sintered ore in which a deterioration in quality is inhibited by using a sintering raw material containing such iron ore and dust.A method for manufacturing sintered ore, in which a sintering raw material containing at least an iron-containing raw material, a CaO-containing raw material, and a bonding agent is granulated, and the granulated sintering raw material is sintered in a sintering machine, the method including a measuring process of continuously measuring a component concentration in at least one of the iron-containing raw material, the sintering raw material, and the granulated sintering raw material, and an adjusting process of adjusting at least one of an amount of the CaO-containing raw material added, an amount of the bonding agent added, an amount of water added, and a moving speed of a pallet carriage of the sintering machine in accordance with the component concentration measured in the measuring process.
