Abstract
Abstract
Hydrogen absorption of aluminum melt during melt treatment is one of the important factors that affect the hydrogen content of aluminum melt. In this paper, the effects of several factors (melt temperature, atmosphere humidity, and rotary speed in the rotary impellor degassing process) on hydrogen absorption are investigated quantitatively. It is found that, the higher the melt temperature, the higher the atmospheric humidity, and the higher the rotary speed in the rotary impellor degassing process, the more serious the hydrogen absorption of melt will become.
