田口设计优化的铝合金旋转叶轮除气技术

Optimal Design of Degassing Technology for Aluminum Alloy Rotating Impeller Based on Taguchi Methods

利用田口实验优化法配合水模拟实验法设计了铝合金旋转叶轮除气技术。选用L9田口正交表分析旋转叶轮除气技术的3个控制因子,包括转速、气体流量及叶轮设计。研究结果显示,使用水模拟实验法配合田口实验法,可有效的减少设计优化旋转叶轮除气技术的实验数。通过田口实验法,得出旋转叶轮除气技术的最佳参数组合,其中最重要的控制因子为转头的叶轮数目、转速和气体流量,最佳参数分别为6个叶轮片、转速500rpm及除气气体流量2L/min。

Using the Taguchi methods an optimal degassing technology for aluminum alloy rotating impeller was designed via water simulation. The L9 Taguchi orthogonal table was used to analyze the three controlling factors. Results show that applying this water simulation process combined with the Taguchi method can greatly shorten the experiment time. The optimal structural parameters including the rotating speed, gas flow and number of the impellers for rotating impeller degassing were gained at last, which are 6-piece impellers, 500 rpm and 2 L/min, respectively.
