70 Iron Silicon Inoculant Description
Properties of 70 ferrosilicon inoculant:
1, with the reduction of white mouth, will not significantly increase the amount of eutectic masses, so it can reduce the increase in the degree of friability due to inoculation. Improves the pressure resistance of molding.
2, the surface of the inoculum is very uniform, the recession ability is also quite good.
3, the third point is the melting point is quite low. Due to good solubility, the need can be effectively controlled, it does not cause waste, the effect of inoculation is very significant.

Difference between ferrosilicon inoculant and barium-silicon inoculant
Ferrosilicon inoculant
Ferrosilicon inoculant has different value and market price due to different index content. The effect of 45FeSi inoculum is weak, and the use of 85FeSi is too expensive, so now 75FeSi and 72FeSi are commonly used in steel mills with inoculum. Ferrosilicon in the composition of Ca and Al has a great influence on the effect of inoculum, of which the effect of Ca greater than 0.5% has a strong graphite capacity. 0.5% has strong graphitization ability. The aluminum content of 75 FeSi is 1.5%, 72 FeSi is 2%. Ferrosilicon inoculants are typically 0.2-0.8-mm inoculants with particle sizes of 1-3 mm and 3-8 mm.
Barium-silicon inoculants
Barium-silicon inoculants are mainly used in the production of gray iron and ductile iron. Barium-silicon inoculum used in ductile iron can greatly increase the amount of graphite beads; used in gray iron, it can reduce the tendency of white mouth, refine the grain, promote graphitization, and improve graphite morphology. Silicon-barium inoculant, in addition to improving mechanical properties, has strong antidegeneration ability, silicon-barium for inoculant contains more than 2-4% barium. Generally, the silicon barium inoculant has a particle size of 0.2-0.8 mm, and when the inoculant flow is 1-3 mm and 3-8 mm.
