Aim\ To study the optimal technical parameter of refining with the rotating and puffing method for aluminium alloys. Methods\ According to orthogonal table experimentize theory; the experiment data were treated with difference analytical method to obtain the optimal technical parameters. Results\ The optimal technical parameters: the rotating rate is 600 r/min
flow rate is 0.4 m\+3/h
refine time is 6 min and static time is 5 min. Conclusion\ The rotating and puffing argon method is an effective way to decrease hydrogen content of aluminium alloys.
