Stable blast furnace operation is necessary to reduce energy consumption and CO2 emission in iron and steelmaking industry. In this work, the effects of various in-furnace conditions on drainage behavior were examined with a three-dimensional mathematical model. The results indicate that the void fraction change has the largest effect on the gas - slag interfaces height as in-furnace conditions. The taphole conditions dominate the total drainage rate under the terms of the assumed blast furnace conditions. More than 2mass% FeO in dripping slag will cause deterioration of slag drainage ability due to high slag viscosity around tapholes.
