Abstract
The effect of high intensity ultrasonic vibration (UV) on degassing of pure copper has been studied in this paper. The methods of reduced pressure test (RPT) and direct hydrogen and oxygen measurements are used for the evaluation of degassing efficiency on hydrogen and oxygen concentrations. The results showed that high intensity UV had a significant degassing effect for the commercially pure copper (CP-Cu) melt. With UV, the density index Di was reduced from 11.94 to 1.13%, and the product of hydrogen-oxygen concentration ([%H]·[%O]) in the liquid Cu was decreased to 1.440×10−5 from 6.624×10−5. It was also found that electric power and ultrasonic treatment time could influence the degassing efficiency.
