METHOD FOR PRODUCING METALLIC IRON

摘要

The first purpose of the present invention is to provide a method for producing metallic iron, whereby, in the production of metallic iron by heating an agglomerate, which comprises an iron oxide-containing material and a carbonaceous reductant, in a movable hearth type heating furnace, metallic iron can be efficiently collected from a reduced product containing metallic iron and a slag, said reduced product being obtained by heating the agglomerate. The method for producing metallic iron according to the first embodiment of the present invention comprises: a step for forming an agglomerate of a mixture which comprises an iron oxide-containing material and a carbonaceous reductant; a step for introducing the obtained agglomerate into a movable hearth type heating furnace and reducing the same by heating; a step for crushing a reduced product containing metallic iron and a slag, said reduced product being discharged from the movable hearth type heating furnace, using an impact crusher; and a step for selecting and collecting the metallic iron using a separator.
