FLUIDIZED PRE-REDUCTION FURNACE

摘要

The furnace optimizes reduction operation of iron ore by stabilizing flow of iron ore having a wide range particle distribution in a fluidized bed type prereducing furnace. The furnace comprises, a first prereducing furnace (10) for reducing powder iron and a 2nd prereducing furnace (20) for reducing large particle ore and a 3rd furnace (30) for reducing medium/small particles.
