| Abstract Scope |
In recent years, some steel companies have been reducing the proportion of agglomerates (sinter/pellets) in the blast furnace burden composition while increasing the proportion of natural lump ore, to achieve cost reduction and emission reduction. However, different lump ores entering the furnace will affect the production of the blast furnace to varying degrees, and it is essential to conduct a systematic study on the performance of lump ores. This study employed X-ray fluorescence (XRF) spectroscopy, volumetric method, and X-ray diffraction (XRD) to analyze the chemical composition of three types of lump ores. The thermal decomposition characteristics of the lump ores were investigated using thermogravimetric-differential scanning calorimetry (TG-DSC). Additionally, the thermal decrepitation behavior, reducibility, and softening-melting-dripping performance of these ores were evaluated. Through a systematic comparison of the three lump ores, this research provides insights for optimizing blast furnace burden composition and operational practices. |
