Embodiment 1
[0031] A method for purifying an aluminum alloy melt, comprising the following steps:
[0032] S1: Heat the aluminum alloy raw material in the crucible furnace to 730°C to make a melt;
[0033] S2: Turn on the switch of the movable rotating arm, make the rotating arm rotate and stir at a uniform speed in the aluminum alloy melt, and at the same time, pass N 2 , Cl 2 The mixed gas and refining agent are uniformly sprayed into the aluminum alloy melt through the jet ball and jet pipe of the rotating arm respectively, and at the same time, the scum on the surface of the aluminum alloy melt is removed; the N 2 , Cl 2 The ratio of mixed gas is N 2 : Cl 2 =1:0.05; the rotating arm rotates around the central axis, the rotation angle is 15 degrees, the rotating speed of the jet pipe is 80r / min, and the rotating speed of the jetting ball is 400r / min;
