SUMMARY:The melting progression of H-DRI and the effect of reduction degree on P and V partition
DESCRIPTION:The melting progression of hydrogen direct reduced iron pellets containing metallic iron and residual oxides (flux, gangue and unreduced iron oxide) was studied experimentally at 1773-1873 K. It was found that the autogenous slag formed inside the pellet prior to the iron melting. The autogenous slag formation was initiated by the melting of FeO. The liquid FeO dissolved the remaining residual oxides, forming the autogenous slag inside the pellet pores. After the iron melted, the autogenous slag was released from the pores coalescing into droplets. Phase separation occurred as the slag droplets floated up to the liquid iron surface. The melting speed was found to increase with decreased degree of reduction. The reduction degree also affected the partitions of phosphorus and vanadium between slag and metal.
