摘　　要：通过对ZL101A合金旋转喷吹精炼工艺的正交试验,分析了影响旋转喷吹精炼技术的4个因素,包括喷头转速、氩气流量、精炼温度及除气时间,确定了影响旋转喷吹精炼效果的因素依次为喷头旋转速度、氩气流量、合金液温度及除气时间,得出了最佳工艺参数组合:喷头转速为300r·min-1,氩气流量为3.5L·min-1,合金液精炼温度为700℃,除气时间为15min。Through orthogonal experiment for ZL101A, four factors influencing the process of rotary impeller degassing,such as rotation speed, flux of argon, refining temperature and degassing time were examined, and the influencing sequence on rotary impeller degassing efficiency was presented as follows： rotation speed, flux of argon, refining temperature and degassing time. The optimized processing parameters were presented as follows： rotational speed of 300 r·min-1, the flux about 3.5 L·min-1, and degassing time of 15 minutes at 700 ℃.
