摘要
A fluidized bed reduction method in which powder raw material, including powder ore or partially pre-reduced powder ore, forms a fluidized bed with, and is sequentially reduced by reducing gas while being moved between a plurality of fluidized bed chambers; and to a fluidized bed reduction reactor which can be used in the same method. The movement of the powder ore between the fluidized bed chambers is carried out giving priority to relatively larger powder particles with the aim of improving the stability of the fluidized bed in the fluidized bed chambers. The adjustment of the reducing power of each fluidized bed chamber is made possible by introducing the reducing gas into the fluidized bed chambers in parallel, whereby an increase in the degree of reduction of the raw material can be realised.
