HYL Process for Direct Reduction of Iron Ore – IspatGuru

Apr 22, 2017· Energiron direct reduction process (HYL process) uses a shaft reduction furnace to produce DRI. It is designed to convert iron pellet/lump ore into metallic iron by the use of reducing gases in a solid-gas moving bed shaft furnace. O2 is removed from the iron ore by chemical reactions based on H2 and CO, for the production of highly metallized DRI.
