Embodiment 1
[0017] Weigh a certain weight of primary aluminum, heat it to melt, raise the temperature to above 720°C, and keep it warm for 0.5 hours. Sprinkle or blow the melt composite treatment agent of 1% by weight of the aluminum melt into the molten aluminum, and stir while adding to make the flux fully contact with the molten aluminum. After smelting and settling for 30 minutes, the contents of Ti, Ga, V, etc. in the aluminum melt changed significantly, among which the content of Ti decreased from 0.0179% to 0.0070%, the content of Ga decreased from 0.0168% to 0.0138%, and the content of V decreased from 0.0073 % down to 0.0001%.
Embodiment 2
[0019] Weigh a certain weight of primary aluminum, heat it to melt, raise the temperature to above 720°C, and keep it warm for 0.5 hours. Put or blow the melt composite treatment agent of 1.8% by weight of the aluminum melt into the molten aluminum, and stir while adding, so that the flux is in full contact with the molten aluminum. After smelting and settling for 30 minutes, the contents of Ti, Ga, V, etc. in the aluminum melt changed significantly, among which the content of Ti decreased from 0.0173% to 0.0084%, the content of Ga decreased from 0.0171% to 0.0123%, and the content of V decreased from 0.0071% % down to 0.0002%.
Embodiment 3
[0021] Weigh a certain amount of primary aluminum, heat and melt it, raise the temperature to above 720°C, and keep it warm for 0.5 hours. Put or blow the melt composite treatment agent of 2.7% by weight of the aluminum melt into the molten aluminum, and stir while adding to make the flux fully contact with the molten aluminum. After smelting and settling for 30 minutes, the content of Ti, Ga, V, etc. in the aluminum melt changed significantly, among which the content of Ti decreased from 0.0176% to 0.0071%, the content of Ga decreased from 0.0166% to 0.0142%, and the content of V decreased from 0.0078% down to 0.0001%.
