摘　　要：将电渣重熔过程分为初始阶段与稳定阶段,并对自耗电极从自初始阶段开始熔化到稳定阶段金属熔滴长成的过程进行了数值模拟分析,结果表明,渣池中的电流密度分布决定了渣池中温度的分布规律,在自耗电极形成金属熔滴时,将会使金属熔滴下方渣池产生高温区,从而有利于电渣过程中杂质的去除。The ESR process was divided into the initial stage and stable stage. Apply numerical simulation to analysis the consumable electrode from the beginning of melting in the initial stage to molten metal droplets grow up in stable stage. Results showed that the slag pool current density distribution determines the distribution of slag pool temperature. When the consumable electrode forms molten droplets, it will generate high temperature zone under the molten droplets in slag pool, and it is contributing to the removal of impurities during ESR.
