摘要：
Refining and purification is a significant way to obtain pure and high-quality magnesium alloy melts. This paper summarizes the flux refining methods and non-flux purification methods (blowing purification, filtration purification, electromagnetic purification and ultrasonic purification). It also introduces the composite refining technologies that have been widely researched and applied in recent years, including low-voltage pulse electromagnetic technology, ultrasonic argon purification, self-purification technology and non-flux continuous purification technology. Among them, the non-flux continuous purification technology integrates a variety of purification methods, which can produce high-quality magnesium alloy continuously and steadily, realize environmental protection production, and achieve remarkable technical and economic benefits.
