✦ Synopsis

A continuous hydrogen-removal method for aluminum melt, spray degassing, is used to degass aluminum melt. The effects of various spray degassing parameters on hydrogen content and properties of aluminum are studied. The results show that, too high or too low melt temperature is unfavorable for hydrogen-removal. The high pressure of spraying gas is helpful for hydrogen-removal. The purge gas flow-rate has no effect on degassing efficiency of spray degassing. To gain a high degassing efficiency, bottom-blow purge gas should be combined with spraying process; otherwise, the degassing effect will be poor.
