A PROCESS FOR PRODUCTION OF HIGHLY METALLIZED DRI (DRY REDUCED IRON) WITHOUT REMOVAL OF ZN FROM ZN- BEARING IRON ORES AND OTHER LOW BOILING POINT ELEMENTS

摘要

A process for producing good quality of DRI from iron ores containing higher contents of low boiling point elements like Na, K, Zn etc comprises flowing Co + H2 + N2 reducing gas from the bottom of the reactor equipment to upward direction wherein the downward moving bed of iron ore takes part in reaction in counter current of reduction gas flow and maximum degree of metallization takes place at a temperature between 750° - 800° C inside the reactor characterized in that said maximum degree of metallization of reduced iron ore is achieved without imparting reduction or vaporization of low boiling elements.
