This paper systematically describes the successful development and industrial application of a technology that produces high-quality fluxed pelets using a straight grate at Ansteel. This technology establishes the optimized scheme that the iron concentrate produced by Ansteel is used as the primary iron-bearing material to mix with composite fluxes,to achieve stable production of fluxed pellet of 4 million tonnes per year. The fluxed pellets produced exhibit stable basicity of 1.0,total iron(TFe)grade of approximately 64.0%,compressive strength>2 865 N/P,reducibility index of 78.5%,and low-temperature reduction-disintegrationindex of 11. 19%.Their overallperformance reaches internationally leading standards. Industrial application inblast furnaceshows that ater such pellets are added,the proportion of pelet in the blast furnace burden increases from about 25%（with traditional acid pellets) to a maximum of 36.5%.This resulted in an increaseintheburdenirongradebyover0.97percentagepoints,a reductioninthefuel rateby1.5kg/thot metal,and a decrease in CO, emissions by 24.46 kg per tonne of hot metal. This technology realizes the successful smooth and direct transition from acid pellets to fluxed pellets in blast furnace operation for the first time in China,and provides a complete technicaldemonsrationforproducinghigh-qualityfluxedpeletsfromsimilardomesticironoreresourceslokingforward to the future,this technical route holds broad potential for further innovation in areas such as raw material diversification, productserializationdevelopment,andsmelting technologywith highproportionofpelletinblastfurnace.
