摘要
借助有限元分析软件ANSYS,在电流为600A,频率为2Hz条件下,对大方坯跨结晶器电磁搅拌进行了数值分析·实验结果和模拟结果对比表明,试验结果和数值模拟结果基本相符·重点分析了不同的电流和频率下,铸坯中心磁场强度和节点电磁力的变化规律,结果表明:铸坯中心磁场强度、节点电磁力随电流增大而增加,也随频率增加而增加,在8Hz时达到最大值·
A numerical simulation was conducted at 600 A/2 Hz for the M-EMS behavior of a bloom during continuous casting by virtue of the FEA software ANSYS. The comparison showed that the calculated results conform basically with the experimental data. Discusses emphatically the relationship between the magnetic filed induction or node magnetic force at the centre of bloom and the changing current/frequency. The results show both magnetic induction and node magnetic force at the centre of bloom increase with the current also the frequency, of which the maximum value is found at 8 Hz.
