Abstract：In order to reasonably use fuels and reduce production cost, the effects of coke and coal powders on chemical composition, mineral structure and component, and metallurgical properties of sinter were studied in laboratory. In all tests, the iron ore blends were selected as the iron-contained materials for sintering experiments. When the coke powder was used as the solid fuel in sintering process, the reducibility of sinter at 900℃ was slightly improved while the low temperature reduction degradation index of sinter was worsened. However, with the coal powders as the sintering solid fuel, the mechanical strength and low temperature reduction degradation index of sinter were improved because more interweaving corroded structure formed in sintering process.
