In order to explore the feasibility of producing high-grade oxidized pellets for hydrogen-based shaft furnace from Chengchao iron concentrate, Chengchao ordinary iron concentrate with a grade of 66.14% and a high-grade iron concentrate with a grade of 69.51% are used as raw materials to study the effects of binder ratio, pelletizing moisture on fresh pellet indexes and the influence of preheating roasting system on the quality of finished pellets, and the hydrogen-based reduction characteristics of high-grade finished pellets are detected. The results show that the strength index of high-grade pellets is better than that of ordinary pellets, but the strength of ordinary finished pellets is generally better than that of high-grade finished pellets, and the roasting temperature and time of ordinary finished pellets are lower than those of high-grade pellets. The compressive strength of high-grade finished pellets is 3 186.8 N/P under the conditions of bentonite dosage of 1.1% , preheating temperature of 975 °C , preheating time of 9min , roasting temperature of 1250 °C and roasting time of 18min . At the same time, the expansion results show that when 0.8% Indian bentonite is added, the compressive strength of the finished pellets is 3458N/P , the iron grade is 67.56% , the mass fractions of SiO₂? and Al₂?O_3? are 1.82% and 1.03% , respectively, the reduction index is 8.44, the reduction expansion index is 14.7% at 950 °C , the reduction pulverization index of ＞6.3mm and ＜3.2mm are 83.5% and 9.4% , respectively, and the adhesion index is 0. It meets the requirements of oxidation pellet reduction performance for hydrogen-based shaft furnace reduction by HYL method, and provides a technical basis for the production of high-grade oxidation pellets for hydrogen-based direct reduction in Chengchao iron concentrate.
