PURPOSE: A method for controlling the mixing ratio of pulverized coal injected into a blast furnace is provided to estimate the mixing ratio and grain size distribution of pulverized coal by sampling pulverized coal to be actually supplied, compare the estimated value with the preset optimum value, and compensate the difference. CONSTITUTION: A method for controlling the mixing ratio of pulverized coal injected into a blast furnace comprises the steps of: sampling pulverized coal(S10), measuring the volatile amount of the pulverized coal sample(S20), estimating the mixing ratio of the pulverized coal being supplied from the measured volatile amount(S30), comparing the estimated mixing ratio with a theoretical optimum value(S40), and compensating the calculated difference(S50). |
