Distribution rule of rare earth in aluminum melt under electromagnetic stirring

The movement and distribution of rare earth La on the A356-1.2 % La aluminum alloy melt were studied under the condition of single low frequency rotation electromagnetic field by applying the electromagnetic field stimulation module of Ansoft and flow field stimulation module of Fluent software among Ansys software. The distribution of La in A356-1.2 %La melt with rotation electromagnetic field was studied. The modeling and stimulation of A356-1.2 % La melt was made by electromagnetic stirring with single low frequency and transient time, and the distribution of rare earth La was specifically analyzed at the electromagnetic stirring frequency of 5 Hz, 15 Hz and 30 Hz. The results show that the distribution of rare earth La in A356-1.2 % La melt is more uniform when electromagnetic stirring frequency is 30 Hz. With the increased time and frequency under certain circumstances, the distribution of rare earth La in A356-1.2 % La melt become more homogeneous. It is verified that the analysis of rare earth movement in aluminum-rare earth multiple phase melt can stimulated through the rotation electromagnetic field module in Ansys software and the flow field module in Fluent software.
