Abstract

A control method for a blast furnace according to the present invention includes a temperature distribution estimation step of estimating a temperature distribution at a bottom of a blast furnace by performing heat transfer analysis by using a numerical model of the blast furnace, a determination step of determining a risk of generating a region of poor hot metal flow at the bottom of the blast furnace based on a difference value between the temperature distribution estimated in the temperature distribution estimation step and an actual measurement value of temperature at the bottom of the blast furnace, and a control step of controlling an operating condition of the blast furnace so that the region of poor hot metal flow is not generated, based on a result of the determination in the determination step.
