特点：具有适当大小的表面张力，熔剂与熔体能很好的分离，并且能从熔体中吸附和溶解大量的非金属夹杂物，能达到很好的净化效果。
用途：ZM3、ZM4、ZM6合金精炼。
Characteristic: With appropriate surface tension, flux and melt can be well separated, and can adsorb and dissolve a large number of non-metallic inclusions from the melt, which can achieve a good purification effect.
Purpose:It is used in the refining of ZM3、ZM4 and ZM6 alloy.
