PURPOSE: A method for estimating reduction degradation in a blast furnace based on reduction time is provided to estimate the degradation property of sintered ores according to the residence time of the sintered ores in the blast furnace. CONSTITUTION: A method for estimating reduction degradation in a blast furnace based on reduction time is as follows; a step for inputting the reduction time and initial particle size; a step for setting a reduction time range corresponding to the reduction time; a step for calculating the decreased rate of the particle size due to the reduction with a linear interpolation method; and a step for estimating the particle size after the reduction by decreasing the initial particle size to the calculated particle size.
