Continuous separation of non-metallic inclusions from aluminum melt using alternating magnetic field

摘要

Experiments to continuously separate inclusions from aluminum melt were conducted on a laboratory-scale apparatus by using high-frequency alternating magnetic field. It was found that the separating efficiency of 6-mu m alumina inclusions can exceed 95 percent. The separating efficiency for the square separator channels is significantly higher than that for the circular separator channels under the close processing conditions, which supports that the separating efficiency can be improved by disturbance in the melt.
