Dynamic electromagnetic separation of iron-rich phase inclusions from Al alloy

Electromagnetic separation of the iron-rich phase inclusions from Al alloy was investigated. The influencing parameters including magnetic induction density, the section shape of the separating channel and the length of influential loop of the metal melt on the separation efficiency of iron-rich phase inclusions were studied. The results show that when the proper magnetic induction density (B=0.3T) is applied, rectangle separating channel is used, and the influential loop of the metal melt is long, high separating efficiency of the iron-rich phase inclusions can be obtained.
