| 摘 要： | 低频电磁场作用下铸造铝合金过程中,优化的结晶器应该在电源频率相同、较低的电流下在铝熔体内部能够获得所需要的磁场强度.结合生产实际情况,设计出工业上实用的低频电磁铸造铝合金结晶器.在结晶器外套材料的不同情况下,对低频电磁铸造铝合金过程的电磁场进行了三维有限元数值模拟.模拟结果表明,当结晶器外套为软磁材料时,铝熔体内部磁场强度得到明显加强. |

| Abstract: | The optimized crystallizer should ensure that the desirable magnetic flux density can be realized in Al melt with lower current under the same power-frequent.The industrial practical crystallizer for Al alloy in low-frequent electromagnetic casting was designed based on the above mentioned idea.A 3D FEM numerical simulation of electromagnetic field in the crystallizer with different outer sleeves materials for Al melt in low-frequent electromagnetic casting were conducted.The results showed that the magnetic flux density in the Al melt can be enhanced with outer sleeves of soft magnetic materials in crystallizer. |
| Keywords: | Numerical Simulation Crystallizer Electromagnetic Casting Al Alloy |
