摘要

The fluxing processing, a traditional purification method for magnesium melt, not only bears the risk of flux inclusions but also is facing more and more environmental pressure today. Therefore, the effective substitutes for fluxing processing are paid more attention recently. The mechanical effect generated by ultrasonic field in the media also called as ultrasonic agglomeration in chemical industry could conglomerate solid particulates in suspending liquid and then realize their separation. In this research, it is used to treat magnesium alloy melt with aim to promote and accelerate the separation of oxidation inclusion from melt. The effects of ultrasonic power, ultrasonic processing temperature and the holding time after ultrasonic treatment on the inclusion distribution in the billet were investigated. The results indicate that the ultrasonic conglomeration produced at low power ultrasonic field could be used to promote and accelerate the separation of oxidation inclusions form magnesium melt.
