摘　　要：为了提高AlSi12Fe铝熔体除气和晶粒细化的效果,通过优化超声波功率和对铝熔体处理效率的变量参数,对AlSi12Fe铝熔体进行超声波处理.实验结果:经1000 W超声波功率处理1 min后,40 kg的AlSi12Fe铝熔体的密度当量为1.28%,比处理前降低了45.06%;除气效果明显,晶粒级别由二级细化至一级.表明,利用超声波的空化作用,对铝熔体进行超声波处理,并选择合适的输入功率和处理效率,能实现有效提高铝合金熔体除气的效果和晶粒细化的效果.The aim is to improve the effect of dehydrogenation and grain refinement of AlSi12 Fe aluminum melt.By optimizing the parameters of ultrasonic power and treatment efficiency of aluminum melt,the aluminum melt of AlSi12 Fe is ultrasonically treated by optimizing the ultrasonic power and the variable parameters of the aluminum melt processing efficiency.The density equivalent of 40 Kg AlSi12 Fe aluminum melt is 1.28%after being treated with 1000 W ultrasonic power for 1 minute,which is 45.06%lower than that before treatment,the effect of dehydrogenation is obvious.At the same time,the grain grade is refined from the second level to the first level.By using the cavitation effect of ultrasonic wave,the aluminum melt can be treated by ultrasonic wave,and the effect of dehydrogenation and grain refinement can be effectively improved by selecting appropriate ultrasonic input power and processing efficiency.
