摘　　要：通过对某钢厂40 t偏心电弧炉底吹工艺建立数学模型,利用流体计算软件Fluent数值模拟了不同底吹条件下电弧炉熔池内的流体流动特征,分析了不同底吹流量对流体流动的作用规律。结果表明:随吹气量的增大,熔池表面平均速度不断增大,得出最优的吹气量为30~40 m^(3)/h。同时结合工业生产数据发现,采用底吹搅拌技术后能加速电弧炉熔池的传热和传质速度,缩短冶炼时间,降低生产成本。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 m^(3)/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.
