摘要
研究了超声波熔体处理方法对纯铝铸锭凝固组织的影响,分析了没有添加除气剂不进行超声波处理、只添加除气剂不进行超声波处理、既添加除气剂又进行超声波处理的情况,以及超声波对纯铝凝固组织影响的原因。研究结果表明,采用合适的超声波振动处理时间,可以提高铸锭晶粒的细化率。
In this study, the effect of ultrasonically melt treatment method on solidification structure of pure aluminum ingot was investigated, e.g. without degasser and ultrasonic, with degasser only, with degasser and ultrasonic. Furthermore, the mechanism of ultrasonically treatment on solidification structure of pure aluminum ingot was analyzed. The results were attained in the experiments： by using the method of ultrasonic with optimum ultrasonic vibration time, the grain-refinement efficiency of pure aluminum ingot is increase obviously.
