通过数值模拟对两相和三相结晶器电磁搅拌器作用下钢液内部的磁场和流场进行耦合数值分析,得出了不同相位电磁搅拌时,钢液内部磁感应强度、电磁体积力及搅拌速度的分布规律。模拟结果表明:在相位差为90°的两相电磁搅拌器结晶器电磁搅拌时,钢液内部的磁感应强度、电磁体积力及钢液的搅拌速度要比相位差为120°三相电磁搅拌器的高。计算结果与文献中实验结果及宣钢等厂的生产实践结果一致。
Through the numerical simulation of the coupling of the magnetic field and the flow field in the molten steel under the action of two-phase and three-phase mold electromagnetic stirrer, the results show that the magnetic induction, the electromagnetic force and the stirring speed The distribution of law. The simulation results show that when the phase difference is 90 °, the magnetic induction intensity, the electromagnet volume force and the stirring speed of the molten steel in the two-phase electromagnetic stirrer mold are more than the phase difference of 120 ° in the electromagnetic stirring mold. Three-phase electromagnetic stirrer height of. The calculation results are consistent with the experimental results in the literature and the production practice of the plant such as Xuan Steel.
