| 摘 要： | 低频电磁场作用下铸造铝合金过程中结晶器设计的好坏对保证铸坯质量起到很重要的作用,而在结晶器设计时数值模拟技术是一个重要有效的工具.优化的结晶器应该是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.基于这种思想,根据生产实际情况,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: | A well-designed mould is very important to secure good quality through providing enough magnetic density in the low-frequency electromagnetic casting process of aluminum alloys.Numerical simulation is a cost-effective tool in the design of mould.Optimization mould should be the one that enough density is got with same frequency and lower electric current.Based on this thought,according to practical situation,mould for the low-frequency electromagnetic casting process of aluminum alloys was designed.Three-dimensions FEM simulation of aluminum alloys electromagnetic casting was carried out with different materials of exterior part of mould,a series of analyses and discussions were done.Calculated results show that magnetic density in the aluminum melt is greatly improved when exterior part of mould is made of soft magnetic material. |
