SELF-FLUXING PELLETS FOR USE IN A BLAST FURNACE AND PROCESS FOR THE PRODUCTION OF THE SAME

摘要

Provided are self-fluxing pellets for a blast furnace, characterized in that a CaO/SiO 2 weight ratio C/S is 0.8 or more and a MgO/SiO 2 weight ratio M/S is 0.4 or more; when the iron content (weight %) in the entire pellet is represented by %TFe, %TFe is 65% or less; and the 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: Equation : Ts = 110 × C / S + 100 × M / S + 25 × % TFe - 480
