Application of ultrasonic treating to degassing of commercially pure copper melt: A preliminary investigation

The effect of ultrasonic treatment (UST) on degassing of commercially pure copper (CP-Cu) has been studied by both reduced pressure test (RPT) and direct hydrogen, oxygen measurement, and the results show that UST has a significant degassing effect for the CP-Cu melt. The achieved results indicate that UST would be an alternative process for molten Cu degassing.
