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.
