Abstract

PURPOSE: To prevent the occurence of troubles such as bridging due to fusion of iron oxide pellets to each other in manufacture of sponge iron by reduction of the raw pellets with a hot reducing gas, by charging iron oxide solid granules of a specific diameter into a furnace together with the pellets.
CONSTITUTION: In manufacture of sponge iron with a hot reducing gas by charging usual iron oxide pellets as raw material regulated to 10 W 13 mm into a shaft furnace or a fixed bed retort, the pellets are mixed with iron oxide solid granules with an average diameter of 2 W 5 mm and charged into the furnace. The mixing ratio of the granules is pref. 2 W 50%. Thus, clustering of the raw pellets is effectively prevented, and smooth stable operation can be ensured without increasing press. loss in the furnace.
