Effect of M-EMS Parameters on Quality of 82B High Carbon Steel
In this paper,the rule of M-EMS on Φ250mm 82B high carbon steel during the casting process was investigated by numerical simulation and experiments.The influence of M-EMS current and frequency on distribution of flow field was researched.The simulation results show that: At the same current,velocity increases with the frequency increase.With the increase of frequency,the velocity first decreases and then increases as the frequency increase along the casting direction.At the same frequency,velocity increases with the current increase.The turbulence zone also become more strenuous,especially in free surface,the suitable turbulence is benefit to uniform steel temperature.Experiment results show that the quality defects of 82B high carbon steel can be significantly improved with M-EMS.The zone of central pipe decreases.With the increase of current,equiaxed zone ratio increases.Considered the results of numerical simulation and experiments,the optimized EMS parameters of Φ250mm high carbon steel are the stirring current of 480A and the stirring frequency of 3Hz,which can improve strand quality greatly.
