Direct smelting apparatus and process |
摘要 |
A vessel which produces metal from a feed material by direct smelting is disclosed. The vessel contains a molten bath having a metal layer (15) and a slag layer (16) on the metal layer and a gas continuous space (31) above the slag layer. The vessel includes one or more lances/tuyeres (13) extending downwardly into the vessel and injecting an oxygen-containing gas into the vessel and injecting an oxygen-containing bas into the vessel above the metal and slag layer. The vessel includes a plurality of pairs of lances/tuyeres (11) extending downwardly and inwardly into the vessel and injecting feed material with a carrier gas into the molten bath so as to penetrate the metal layer and generate a bath-derived gas flow which carries molten material upwardly. The pairs of lances/tuyeres are spaced around the circumference of the vessel with one lance/tuyere of each pair injecting metalliferous feed material, at a temperature of at least 200° C. and the other lance/tuyere of each pair injecting carbonaceous material, at a temperature less than 200° C.
