PREREDUCTION FURNACE OF A SMELTING REDUCTION FACILITY OF IRON ORE

摘要

A prereduction furnace of a smelting reduction facility of iron ore consisting of a fluidizing prereduction chamber installed at the upper part of the prereduction furnace wherein iron ores are fed and prereduced, a gas blowing chamber installed at the lower part of the prereduction furnace wherein a reducing gas is fed, a ceramic main body of a distributor installed between the fluidizing prereduction chamber and the gas blowing chamber, a metal box attached to the bottom side of the main body, wherein a cooling fluid flows, which prevent adhesion of dusts in the reducing gas, nozzles passing through the main body and the metal box for injecting the reducing gas in the blowing chamber into the prereduction chamber and a discharge pipe for discharging prerduced iron ores installed at a bottom center of the prereduction chamber extending through the ceramic main body, the metal box, and a bottom of the gas blowing chamber.
