Method of producing metallic iron and raw material feed device |
| abstract |
Method of producing granular metallic iron, including: solid-state reducing a formed raw material comprising a cardonaceous reductant and a substance containing iron oxide; and carburizing reduced iron resulting from the solid-state reduction with carbon contained in the carbonaceous reductant to cause the reduced iron to melt, while separating off gangue components and causing resulting molten metallic iron to coalesce into the granular metallic iron, wherein an atmospheric gas present in proximity to the formed raw material in the carburizing and melting step has a reduction degree of not less than 0.5. Method of producing metallic iron, including forming a deposit layer containing slag produced in the reduction melting process on hearth refractories. Device for supplying an auxiliary raw material to a hearth of a moving hearth type iron reduction melting furnace including a supply duct vertically with a ceiling portion of the furnace. |
