| 摘 要： | 通过向Al熔体中加入SiO2颗粒,成功制备了Al-10%Al2O3复合材料;并采用远大于集肤层厚度的直径30 mm陶瓷分离管和中空管进行了分离实验.结果表明大尺寸分离管同样能实现电磁净化,只是分离时间比中空管略长,可能是因电磁搅拌效应引起的流动造成的.对含有30～200 μm Al2O3颗粒的铝熔体的电磁连续净化实验结...

| Abstract: | Al-10%Al2O3 composite material is successfully fabricated by adding SiO2 into the pure aluminum melt,and used to engage in the electromagnetic separation experiment through the ceramic separation pipes of 30 mm diameter far bigger than the skin depth and hollow pipes.It is found that the Al2O3 particles accumulate in periphery of specimen by separation pipes with big diameter,which may be helped by the flow caused by electromagnetic stirring,although it takes more time to reach the periphery than that of ho... |
