Fundamental and applied researches have been made of inclusion behaviors in molten aluminum and their elimination by electromagnetic cyclone to realize the advanced aluminum recycling. In the fundamental studies, electromagnetic separation of harmful inclusion, Al3Fe, structural analysis of SiC cluster by the synchrotron radiation, and fluid-dynamic behavior of solid particle in a turbulent shear flow have been made to obtain academic knowledge of inclusion particle behaviors in molten aluminum. In the development study of the electromagnetic cyclone, numerical simulation and water model study have been performed to make clear the fluid-flow characteristics and particle transfer toward the wall by centrifugal and magnetic forces. Based on these results, a test equipment has been fabricated and utilized for separating oxide inclusions from molten aluminum. High separation efficiencies have been verified by the test.

为实现铝液的深度回收，对铝液中夹杂物的行为及电磁旋流器去除夹杂物进行了基础和应用研究。在基础研究方面，通过对铝液中有害夹杂物Al_3Fe的电磁分离、同步辐射SiC团簇结构分析以及固体颗粒在湍流剪切流中的流体动力学行为的研究，获得了铝液中夹杂物颗粒行为的理论认识。在电磁旋流器的开发研究中，通过数值模拟和水模型研究，对离心力和磁力作用下的流体流动特性和颗粒向壁面的转移进行了研究。在此基础上，研制了分离铝液中氧化物夹杂的试验装置。试验表明，该分离器具有较高的分离效率。
