Abstract：In order to improve the metallurgical properties of sintering ore， experiments of oxygen enriched sintering process of iron ore powder were carried out with different oxygen circulation of 0 m3/h， 6 m3/h， 7 m3/h and 8 m3/h， respectively. Based on the technical parameters， such as exhaust gas temperature， shrinkage percentage and sintering speed， and phase analysis results of sintering ore， the effects of oxygen enrichment on the sinter yield， utilization coefficient， drum strength and particle size distribution of sintering ore were studied. The results show that the overall performance of sintering ore is best when oxygen enrichment is 7 m3/h. Compared with the reference sample， the proportion of needle-like calcium ferrite in the sintering ore is significantly increased， and the sinter yield， drum strength， abrasion resistance index are increased by 12.03%， 0.66 MPa and 1.2%， respectively. In addition， compared with the reference sample， the FeO content in the sintering ore is decreased and there is no obvious influence on the other chemical composition. The oxygen enriched sintering can improve the strength of sintering ore and reduce the coke rate of blast furnace smelting. The experimental study on oxygen enriched sintering of iron ore powder has significance on improving the smelting efficiency and reducing the production costs.
