| Abstract |
| The Steel flow pattern in the mold is investigated in a wide slab caster with the bifurcated nozzle of downward 25 degrees that is equipped with Electro Magnetic Level Accelerator (ELMA) system. It applies a low frequency alternating magnetic field with the moving direction from the center of the mold to the narrow face. After solving the fluid dynamics numerically, inclusion particle trajectories are calculated using Lagrangian particle tracking method. The simulation results show that EMLA mode eliminates the negative impact of wide slabs by transforming the single roll pattern generated by argon into optimized double roll pattern. This paper presents the optimum electric current and demonstrates the relevance of flow control and inclusion behaviour. |
