PROCESS FOR PRODUCING SPONGE IRON |
摘要 |
<p>A process is disclosed for producing sponge iron by direct reduction of particulate, iron oxide-containing materials. A reduction gas formed in a melting-gasification zone from carbon-yielding materials and oxygen-containing gas is introduced into a reduction zone in which the iron oxide-containing materials are located. The process has the following characteristics: a reduction gas which contains from 20 to 100 g dust per Nm3 with a carbon content from 30 to 70 % by mass is introduced into the reduction zone; and the iron oxide-containing materials are exposed to the reduction gas for a period of time longer than that required to finish reduction. This process is suitable for producing sponge iron with an increased carbon content.</p> |
