Ferro Silicon Barium Inoculant 5-35mm For Steelmaking Additives
Si-Ba-Ca alloy is a kind of graphite can promote graphitization, reduce the tendency of white mouth, improve the morphology and distribution of graphite, increase the number of eutectic groups, refine the matrix structure, it has a good effect in a short time (about 5-8 minutes) after inoculation. Mainly suitable for various situations of general casting or late instantaneous inoculation.
Good inoculation has the following effects:
Eliminate or reduce the tendency of white mouth;
To avoid the occurrence of supercooled tissue;
Reduce the sensitivity of the wall thickness of cast iron, so that the difference of the microstructure of the thin and thick section of the casting is small, and the hardness difference is small.
It is beneficial to nucleation of eutectic group and increase the number of eutectic group.
Product Function
1.Improve steel quality, reduce the cost and save aluminum, it is especially applied in continuous casting steel of deoxidizing requirements.
2. It can not only meet the deoxidizing requirements of steelmaking, but also have the performance of desulphurization, in addition have advantages of big specific gravity and strong penetration.

Applications
Application:
Deoxidizer: Ferro silicon is used in the steelmaking industry as a precipitation deoxidizer and diffusion deoxidizer.
Reducing agent: high-silicon ferro silicon or siliceous alloys can be used as reducing agents for the production of low-carbon iron alloys in the ferroalloy industry.
Alloying agent: Ferro silicon can be used as alloying agent for low-alloy structural steel, composite steel, spring steel, bearing steel, heat-resistant steel and electric silicon steel smelting, to produce single crystal silicon or to prepare non-ferrous metal alloys.
