Process of producing molten metals |
摘要 |
A molten bath-based direct smelting process for producing metals from metal oxides (including partially reduced metal oxides) is disclosed. The process includes causing upward movement of splashes, droplets, and streams of molten material from a metal layer (15) of the molten bath which: (i) promotes strong mixing of metal in a slag layer (16) of the molten bath so that the slag layer (16) is maintained in a strongly reducing condition leading to FeO levels below 8 wt % based on the total weight of the slag in the slag layer (16); and (ii) extends into a space above a nominal quiescent surface of the molten bath to form a transition zone (23).
