SELF-FLUXING PELLETS FOR BLAST FURNACE AND METHOD FOR MANUFACTURING THE SAME |
摘要 |
Provided are self-fluxing pellets for a blast furnace, characterized in that a CaO/SiO2 mass ratio C/S is 0.8 or more and a MgO/SiO2 mass ratio M/S is 0.4 or more; when an iron content (mass %) in the entire pellet is represented by % TFe, % TFe is 65 or less; and a temperature Ts (unit: ° C.) at which the pressure loss starts to increase sharply in a loaded high-temperature reduction test and which is calculated by the equation below is 1290° C. or higher: Ts=110×C/S+100×M/S+25×% TFe−480   Equation:
