APPARAUTS FOR MANUFACTURING IRON CARBIDE BEARING DRECT REDUCED IRON

摘要

PURPOSE: An apparatus for manufacturing iron carbide bearing drect reduced iron is provided to reduce fuel cost by increasing reduction and melting rate and to improve fusibility. CONSTITUTION: An apparatus for manufacturing iron carbide bearing drect reduced iron includes a heating furnace, one or more reduction furnace, and a carbonization kiln. The heating furnace preheats iron ores. One or more reduction furnace reduces the preheated fine ore. The carbonization furnace carbonizes the reduced iron ore to H2S containing reduction gas supplied from the outside.
