Domestic spinning rotor technology need to be exploited both in the sense of melt treatment process itself and comparing with overseas advanced degassing equipments was pointed out in the end.
The effect of melt treatment method on degassing efficiency of ultrasonically refined pure aluminum ingots was investigated. Furthermore, the mechanism of ultrasonic degassing was analyzed.
研究了不同的熔体处理方法对纯铝铸锭超声波除气的影响，分析了影响超声波除气效果的原因。
