Abstract

See full text

The reduced iron manufacturing method of the present invention includes preparing an agglomerate by agglomerating a mixture containing an iron oxide-containing substance and a carbonaceous reducing agent, and preparing reduced iron by heating the agglomerate to reduce iron oxide in the agglomerate, characterized in that Expression (I) as follows is satisfied:

description='In-line Formulae' end='lead'Cfix×Xunder105/OFeO≤51  (I)description='In-line Formulae' end='tail'

where OFeO is the mass percentage of oxygen contained in the iron oxide in the agglomerate, Cfix is the mass percentage of total fixed carbon contained in the agglomerate, and Xunder105 is the mass percentage of particles having a particle diameter of 105 μm or less with respect to the total mass of particles configuring the carbonaceous reducing agent.
