METHOD FOR PREDICTING OF GAS USING RATIO IN BLAST FURNACE

摘要

The present invention provides a method for predicting a gas utilization rate in a blast furnace which can improve work efficiency. According to an embodiment of the present invention, the method for predicting a gas utilization rate in a blast furnace comprises: a step of alternately supplying a steel making material and fuel into a reactive simulation device of a blast furnace, and allowing the steel making material and the fuel to react by preset temperature, carbon monoxide (CO), and hydrogen (H_2) gas partial pressure conditions and time; a step of analyzing exhaust gas produced during the reaction to derive the carbon monoxide and the hydrogen gas utilization rate to acquire data; a step of using the carbon monoxide and the hydrogen gas partial pressure, and the acquired monoxide and hydrogen gas utilization rate data to write a regression linear equation; and a step of deriving a correlation between the hydrogen gas partial pressure (pH_2/pCO) and the monoxide and the hydrogen gas utilization rate for the carbon monoxide partial pressure from the regression line equation to derive the monoxide and a hydrogen gas utilization rate prediction formula.
