摘　　要：电渣熔铸 (ESC)是一种用电加热的方法进行金属冶炼和成型的铸造方法 ,熔铸过程中自耗电极与渣池的接触界面是渣池能量的入口 ,针对平底型电极和锥底型电极两种模型进行了渣池的热电场耦合模拟 ,分别获得了 2种模型的温度场和电场分布规律 。Electroslag casting is a casting method that makes the metal smelting and molding by electricity. The interface of the self-consumable electrode and slag is the energy’s entrance in the electroslag casting process. The slag’s thermoelectricity coupling simulation has been done on the plane end electrode model and cone-shape end electrode model. Each of the model’s temperature field and electric field has been got, and the essentiality of the electrode’s end shape to the electroslag casting process is also expatiated.
