摘　　要：建立了感应线圈电流与磁通密度的关系,研究了不同工艺参数下铝合金熔体电磁净化的效果。结果表明,在稳恒磁场中,直流电流越大,杂质颗粒所受挤压力越大,较易从铝熔体中分离出去;保温时间对杂质颗粒分离净化的效果也有显著影响。The experiments of electromagnetic separation of inclusions from molten aluminum alloy were conducted by a separator. The relationship between t he coil current and the magnetic flux density has been established. The experime ntal results show that,the higher the current is,the higher the separation effic iency is;with the increasing of processing time, more efficient results of separ ation are obtained.
