The influence of oolitic hematite on the compressive strength and metallurgical properties of oxidized pellets was examined. The experimental results indicate that when the proportion of oolitic hematite does not exceed 8%, the compressive strength of the pellets can reach over 2500 N when roasted at 1250°C for 15 min. When the proportion is increased to 10%, the compressive strength remains above 2500 N after roasting at 1250°C for 20 min. As the proportion of oolitic hematite increases, the reduction expansion rate of the pellets decreases; however, the reducibility also diminishes, and the softening and dripping performance deteriorates. Take into account the characteristics of the comprehensive burden structure in blast furnace operations, the proportion of oolitic hematite in pellet production can be increased to 10.0%.
