Aluminum has high recyclability and promising future,so aluminum recycling is important for the future society.However aluminum recycling has some problems;one problem is inclusions remaining in final aluminum products.In this study,we have proposed a new separation process of inclusion particles from molten aluminum;it is the electromagnetic cyclone separator,which consists of the liquid cyclone and the electromagnetic separator.We carried out water model experiments,in which the magnetic separation was used instead of the electromagnetic separation.A theoretical model to estimate the separation efficiency was developed and the results agreed with the water model experiments.The theoretical model was used to estimate the separation performance of the electromagnetic cyclone separator for molten aluminum,and it was predicted that the separator was effective clarification process for aluminum recycling.
Aluminum has high recyclability and promising future, so aluminum recycling is important for the future society. Host aluminum recycling has some problems; one problem is inclusions remaining in final aluminum products. In this study, we have proposed a new separation process of inclusion particles from molten aluminum; it is the electromagnetic cyclone separator, which consists of the liquid cyclone and the electromagnetic separator. A carried out water model experiments, where the magnetic separation was used instead of the electromagnetic separation. A theoretical model to estimate the separation efficiency was developed and the results agreed with the water model experiments. The theoretical model was used to estimate the separation performance of the electromagnetic cyclone separator for molten aluminum, and it was predicted that the separator was effective clarification process for aluminum recycling.
