Abstract：

The　3003　aluminum　alloy　melt　was　treated　with　three　types　of　melt　purification,　and　the　effect　of　melt　purification　on　the　microstructure　and　mechanical　properties　of　the　alloy　was　investigated.　The　results　show　that　the　impurity　content　of　3003　aluminum　alloy　with　untreated　(UT)　reached　0.6801%.　After　the　process　of　conventional　purification　treatment　(CPT)　and　efficient　purification　treatment　(EPT),　the　impurity　content　of　the　alloy　decreased　significantly,　and　the　fluidity　of　aluminum　melt　was　improved.　Finely　dispersed　inclusions　particles　can　promote　nucleation,　refine　the　size　of　the　cast　crystal.　Alloy　strength　and　plasticity　have　increased　using　the　process　of　CPT　and　EPT,　in　particular,　EPT　is　the　most　obvious.　It　shows　that　the　purity　of　aluminum　melt　plays　a　key　role　in　the　mechanical　properties　of　the　alloy.　©　2018　Trans　Tech　Publications,　Switzerland.
