To further decrease the fuel consumption of blast furnace in Tangshan Guofeng Iron and Steel Co Ltd, measures of improving the quality of sinter and pellet and the performances of raw materials were put forward through phase analysis and physical and chemical performance testing. The measures of increasing the grade of sinter, decreasing the sinter reduction degradation index at low temperature, and increasing the sinter soft melt performance at elevated temperature, as well as the reasonable process parameters of sintering were described in detail.
