Ferro Silicon Barium Inoculant is a high-performance additive widely used in the casting industry to improve the quality and mechanical properties of cast iron, especially gray iron and ductile iron. This inoculant combines the nucleating power of silicon with the refining effects of barium, promoting fine graphite formation and uniform microstructure.

Ferro Silicon Barium Key Features

• Enhances graphite nucleation and promotes even distribution of graphite flakes or nodules.

• Reduces chilling and carbide formation, ensuring smooth solidification.

• Improves mechanical properties such as tensile strength, impact toughness, and machinability.

• Provides a stable inoculation effect for consistent casting quality.

• Suitable for various grades of cast iron, including gray iron and ductile iron.

Uses of Ferro Silicon Barium

1. Inoculant for Gray and Ductile Iron

FeSiBa is especially effective as an inoculant for gray cast iron and ductile iron. It promotes the formation of fine and evenly distributed graphite flakes or nodules, improving mechanical properties such as strength and toughness.

2. Reducing Chill Tendency in Castings

Barium in the alloy reduces the formation of carbides and white iron, helping to minimize chilling effects and ensure a softer, more machinable structure.

3. Enhancing Graphite Nucleation

FeSiBa increases the number of graphite nucleation sites, leading to better control of microstructure and consistent quality in castings.

4. Steelmaking Deoxidizer

In steelmaking, FeSiBa serves as an efficient deoxidizing and desulfurizing agent, thanks to the strong affinity of barium and silicon with oxygen and sulfur.

5. Stabilizing Solidification Process

It helps to refine the grain structure and stabilize the solidification of molten metal, reducing casting defects such as porosity and shrinkage cavities.
