| Abstract Scope |
This study systematically investigated the consolidation mechanism of hematite pellets and its impact on pellet quality through experiments on producing basic pellets with varying proportions of hematite. The experimental results indicate that as the hematite ratio increases, the compressive strength of the pellets shows a decreasing trend, the reduction swelling index decreases initially and then increases, while the reducibility demonstrates an improving trend. When producing basic pellets with 100% hematite and a basicity of 1.1 under conventional roasting conditions, the compressive strength reached 1739 N, the reduction swelling index was 11.97%, and the reducibility was 84.4%. Based on microstructural and energy-dispersive spectroscopy (EDS) analysis, the consolidation of hematite pellets is primarily dominated by liquid-phase bonding. It is necessary to further increase the roasting temperature to enhance solid-state consolidation and thereby improve the compressive strength of the pellets. |
