| Abstract: | Considering the requirement for cooling of primary gas from final reduction vessel and efficiency of prereduction in two-step smelting reduction iron-making process like Corex, the advantages of the hydrogen-enriching reform of primary gas and pre-reduction with hydrogen-enriched reduction gas are analyzed. The disadvantages and countermeasures are discussed. The hydrogen enriching reform of the primary gas for pre-reduction is feasible. |
