摘要

Solid fuel combustion provides the necessary heat for an iron ore sintering bed. However, with an increase in low-grade iron ores (Alumina > 3%), the solid fuel requirement increases, as it increases the viscosity of the sinter melt, making it more difficult for the iron ore particles to fuse together. This results in a longer sintering time and higher solid fuel rate to achieve the desired sinter quality, thereby affecting the subsequent CO2 emissions. Reducing the coke consumption is a key factor not only affecting the issue of global warming but also the iron-making processes. This study has demonstrated various possible methods for improving the granulation process and permeability by controlling the coke second-stage addition ratio (CSAR). Optical microstructural analysis revealed that as CSAR increases, the high Fe-low Si Phase SFCA-I (needle-shaped morphology) generally appears at the sinter top bed. This process is a promising solution to reduce the solid fuel consumption in the sintering process at the same levels of sinter quality and yield.
