| titleOfInvention | Fine direct reduced irons containing iron carbide and preparation apparatus thereof |
| abstract | Disclosed are fine direct reduced irons containing iron carbide and a preparation apparatus thereof. The fine direct reduced irons containing iron carbide of the present invention contains 20-30 wt% of iron carbide by reducing poorly reducible ultrafine ore in a reduction furnace and forming iron carbide on the surface by carbonization in a carbonization furnace. The apparatus for preparing fine direct reduced irons containing iron carbide of the present invention can effectively reduce and carbonize fine iron ore by selectively using hydrogen sulfide contained in a reducing gas in a carbonization furnace and a reduction furnace. The carbon content in fine direct reduced irons is increased by applying fine direct reduced irons containing iron carbide of the present invention, thereby improving melting properties, and it is possible to reduce fuel costs due to the increase of reduction and melting velocities. |
