What is the role of barium silicon inoculant

Inoculants have ferrosilicon inoculants, barium silicon inoculants, etc., each inoculant has different effects, Kangxin metallurgy takes you to understand the barium silicon inoculants:

1. Fine graphite, A-type graphite in gray iron castings, for ductile iron castings, it can make the graphite in ductile iron fine, round, and improve the nodularization grade;

2. It can reduce the subcooling degree of molten iron, the precipitation of graphite, significantly reduce the tendency of white mouth, reduce the relative hardness, and improve the cutting performance of castings;

3. Strong anti-regression ability, the anti-regression time is twice that of 75 silicon, and the amount of barium silicon inoculant is lower than half of that of 75 ferrosilicon inoculating agent, while preventing the associated spheroidization decline;

4. The wall thickness sensitivity is small, which improves the uniformity of the section and reduces the tendency of shrinkage;

5. Stable chemical composition, uniform processing particle size, small composition and quality deviation;

6. Low melting point (less than 1300°), easy to absorb melting during gestational treatment, and there is very little dross.
