摘　　要：通过将直流条件下的Ｍａｘｗｅｌｌ方程和Ｎａｖｉｅｒ－Ｓｔｏｋｅｓ方程相结合，研究了熔池参数变化对炉内熔体搅拌产生的影响。直流电弧炉的熔地参数对熔体搅拌影响较大。高径比较大的熔池，对熔体的搅拌效果优于高径比较小的；炉底电极直径较大的熔池的搅拌效果优于炉底电极直径较小的。Stirring characteristic of metal bath in the DC arc furnace with different bath parameters was studied by combining Maxwell’s equations with Navier-Stokes equations.The results showed that the bath parameter of the DC arc furnace had great effect on stirring of metal bath.The DC arc furnace with great H/D and large bottom electrode had good stirring effect than that with small H/D and small bottom electrode.
