Problems solved by technology

[0004] In addition, the high content of inclusions and gases in magnesium alloys limits the potential of magnesium alloy materials.
The traditional flux refining process is easy to produce flux inclusions, which is easy to corrode equipment and pollute the environment at high temperature, and the magnesium chloride in the flux can react with rare earth elements, resulting in the loss of expensive rare earths, weakening the impurity removal and purification of rare earth elements, and the ability to refine grains effect, affecting the quality of rare earth magnesium alloys
