Inoculant FeSiBa

The mechanical properties of gray cast iron largely depend on its microstructure. Gray cast iron without inoculation treatment has unstable microstructure, low mechanical properties, and white fractures easily appear in the thin wall of the casting. In order to ensure uniform and good casting quality, inoculation treatment is essential.

1. Increase the graphitized structure in the cast iron, refine the graphite, promote the A-type graphite in the gray cast iron, and improve the strength.
2. Effectively reduce the undercooling of the molten iron, promote the precipitation of graphite, significantly reduce the tendency of white fracture, reduce the relative hardness, and improve the cutting performance of castings.
3. The addition amount of ferrosilicon barium inoculant is less than half of the 75% ferrosilicon inoculant, at the same time, avoid the associated nodulation effect decline.
4. Ferro silicon Barium inoculant ensure the overall quality balance of iron castings and improve the uniformity of section.
5. The ferrosilicon barium inoculant has a low melting point (less than 1300°), is easy to blend into the molten iron and mix evenly, and there is very little scum.
