The Effect of Electromagnetic Vibration on the Continuous Elimination of Inclusions in Molten Aluminum Alloy by Electromagnetic Force

Abstract:

The separation system including a DC electric field with steady magnetic field was adopted for removal of inclusion in molten Al alloy. But, very small inclusions, which less than 10 ㎛ are not eliminated. So, firstly, small inclusions are agglomerated by low frequency electromagnetic vibration. And then, we adopting the previously used electromagnetically inclusion removal process. Experiments were carried out on commercial die casting aluminum alloy A380 (JIS: ADC 10). Inclusion was separated continuously. XRF was used for compositional test and PoDFA for cleanliness test. Chemical composition of specimen was not changed and UTS, elongation and cleanliness were increased.
