特點：具有適當大小的表面張力，熔劑與熔體能很好的分離，並且能從熔體中吸附和溶解大量的非金屬夾雜物，能達到很好的凈化效果。
用途：ZM3、ZM4、ZM6合金精煉。
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.
