Abstract

Provided is a method for producing a reduced iron agglomerate, which comprises introducing an agglomerate comprising an iron-oxide-containing substance, a carbonaceous reducing agent, a melting point adjuster and an aid for the melting point adjuster onto a furnace bed of a moving-bed-type heating furnace and then heating the agglomerate on the furnace bed to reduce iron oxide in the agglomerate; and melting the resultant product by additional heating to cause the coalescence of an iron component, thereby producing the reduced iron agglomerate, wherein an agglomerate containing the melting point adjuster that has an average particle diameter of 0.3 mm or less and in which the content of a particle diameter of 0.5 mm or less in an amount of 55 mass % or more is used. Thus, provided is a method which can improve the yield of a reduced iron agglomerate having a large particle diameter and can also reduce the amount of time required for the production of the reduced iron agglomerate to improve the productivity of the reduced iron agglomerate.
