Abstract：Considering the requirement for cooling of primary gas from final reduction vessel and efficiency of prereduction in twostep smelting reduction ironmaking process like Corex, the advantages of the hydrogenenriching reform of primary gas and prereduction with hydrogenenriched reduction gas are analyzed. The disadvantages and countermeasures are discussed.The hydrogen enriching reform of the primary gas for prereduction is feasible.
