摘　　要：研究了除气剂和超声波对Al-1.65%Si铸锭除气的影响,如:没有添加除气剂和超声波处理、只添加除气剂不进行超声波处理、即添加除气剂又进行超声波处理的情况。分析了超声波除气效果的原因。研究结果表明,采用超声波振动处理的方法,可显著地降低铸锭内的含气量。In this study, the effect of degasser and ultrasonic on degassing efficiency of Al- 1.65 % Si ingots was investigated, e.g. without degasser and ultrasonic, with degasser only, with degasser and ultrasonic. Furthermore, the mechanism of ultrasonic degassing was analyzed. The results were attained in the experiments： by using the method of ultrasonic vibration treatment, the value of porosity volume is decrease obviously.
