| Research Abstract |
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.
