Dynamic Mesh-Based Approach for Simulation of an Electromagnetically Controlled Vibrating- Electrode Electroslag-Remelting Furnace
A transient fully coupled mathematical model using the magnetohydrodynamic multiphase method and based on a dynamic mesh-based approach has been developed to simulate the temperature field and molten pool shape in relation to the slag depth in an electromagnetically controlled vibrating-electrode electroslag-remelting furnace. The results show that changing the fill ratio significantly influences the velocity, temperature, and metal pool profile. When the slag depth is increased to 140 mm, the maximum velocity rises to 0.243 m/s, approximately 30% higher compared with the case of 100 mm slag depth ; the hottest zone area (T > 2150 K) dramatically enlarges towards the slag/air interface and covers over half of the slag layer ; the maximum and average temperature increment in the vertical vibration mode are 75 K and 47 K, respectively, being much higher compared with other modes ; the deepest distance of two-phase region decreases from 0.039 m to 0.019 m.
