  • Patent number: 5078787
    Abstract: A method and apparatus for the gaseous reduction of particulate iron ores, wherein the ore or is fed to a vertical moving bed direct reduction reactor, reduced therein, and discharged as hot sponge iron. The ore is charged to the top portion of the reduction zone of the furnace wherein the bed of particles which descend by gravity is reduced by a hot reducing gas largely composed by carbon monoxide and hydrogen. The hot reducing gas is divided in two portions, a first portion which flows upwardly through the reduction zone to reduce the ores therein, and a second portion which flows downwardly through a lower discharge zone to maintain the bed at a suitable temperature level. Finally, the product sponge iron is discharged from the bottom portion of the discharge zone of the furnace and conveyed, for example, to be melted in an electric arc furnace or to be briquetted in a briquetting machine coupled to the reduction reactor.
