Abstract

Abstract

This paper establishes a mathematical model of bottom gas blowing for a 40 t eccentric electric arc furnace in a steel plant. The fluid flow characteristics in the bath of an electric arc furnace under different bottom blowing conditions were numerically simulated using Fluent software. The effect of different bottom blowing rates on fluid flow is analyzed. The results show that the blowing gas increases the average velocity of the molten pool surface. The optimum blowing rate is 30 ~ 40 m³/h. At the same time, combined with the industrial production data, it is found that the bottom-blown stirring technology can speed up the heat and mass transfer of the melting pool, shorten the smelting time, and reduce the production cost.
