Title: Purification effects of glass flux on A356 melt
Abstract: In order to remove hydrogen and inclusions from A356 alloy melt,a low melting-point glass flux,JDN-Ⅱ,was developed.The results indicated that JDN-Ⅱ flux has distinct effect of purification and protection on A356 alloy melt.When the dosage of the flux was 3%,the content of hydrogen in A356 melt was only 2.6 mL/kg at 857 ℃ and 0.7 mL/kg even at 750 ℃.In the meantime,the mechanical properties of the alloy increase greatly with the covering of 3% JDN-Ⅱ flux.Compared with no flux,the tensile strength of A356 alloy increases by 9.42% and the elongation increases by 22%.The purification mechanism of JDN-Ⅱ glass flux was discussed too.
