摘要 利用镁合金快速定量测氢仪研究了通Ar除气对AZ91镁合金熔体除气处理的效果,以及通Ar流量、通Ar时间及精炼温度三因子对精炼效果的影响.运用正交试验方法找到了通Ar除气工艺的最佳工艺参数匹配,即通Ar流量为1~1.5L/min,通Ar时间为20~25min,镁液温度为725~750℃.揭示了主要工艺参数对镁合金熔体净化的影响规律.

Abstract:Purging effects of Ar fluxing were investigated with an instrument for measuring hydrogen content in magnesium alloy melt,and the influence of three factors of Ar flow rate,degassing time and temperature of magnesium melt on purging effect were studied.The optimal parameters were obtained by experiment under conduction of orthogonal test design that Ar flow rate was 1-1.5L/min,degassing time 20-25min and temperature of magnesium melt 725-750℃.In addition,a series of parametric studies were conducted to demonstrate the influence of several key parameters on the effectiveness of purifying magnesium alloy melt.
