依据正交表,用极差分析法对试验数据进行处理来确定旋转喷吹法的最佳工艺参数,其最佳工艺参数组合:旋转速度为600r/min,流量为0.4m3/h,精炼时间为6min,静置时间为5min。
The rotating and puffing argon method is an effect way to decrease hydrogen for aluminum alloys. According to orthogonal table experiment theory, the experiment data were treated with using difference analytical method to obtain the optimal techniques parameters. The optimal techniques parameters: the rotate rate is 600 r/min, flux is 0.4 m3/h, refine time is 6 min and static time is 5 min.
