Abstract
Provided is a reduced iron production method that can efficiently produce reduced iron without preheating raw materials. The reduced iron production method includes charging an agglomerate, which is a raw material of reduced iron, into a reducing furnace while introducing a reducing gas, which contains hydrogen as a main component, into the reducing furnace, and reducing iron oxide contained in the agglomerate by the reducing gas to obtain reduced iron, where the agglomerate to be charged into the reducing furnace is an agglomerate that retains heat obtained during its production, and the heat is used in a reduction reaction of the iron oxide.
