中文摘要:在旋转喷吹条件下,通过增加阻流板,研究了在ZL702A铝合金熔体中通入Ar后的除气效果,利用正交试验对ZL702A进行了除气效率的分析。结果表明,除气时间、气体流量和转子转速是影响除气效率的三个主要因素。
英文摘要: The effects of degassing with Ar in ZL702A aluminium melt under rotating impeller condition by adding spoiler were studied, the efficiency of degassing was analyzed by orthogonal experiments. The results show that the degassing time, the flow of the gas and the speed of the rotor are three main factors.
