Introduction to Ferrosilicon Grain Inoculant

FeSi grain inoculant is produced by crushing ferrosilicon into small pieces and screening them through specific mesh sizes. Essentially, it consists of small grains obtained by crushing and sieving ferrosilicon natural blocks and standard blocks. This material is widely used not only as an effective deoxidizer and alloying agent in steelmaking but also as a crucial metallurgical material in the iron casting industry. Ferrosilicon grain is favored for its low cost and ease of melting, making it an essential component in cast iron production. It effectively promotes the formation and spheroidization of graphite, which is particularly important in the production of ductile iron.

Advantages of Ferrosilicon Grain Inoculant

Cost-effective: Ferrosilicon grain is more economical compared to other metallurgical materials, reducing production costs.
Promotes Graphitization: It helps form A-type graphite in gray castings, increases the number of eutectic clusters, and reduces segregation.
Improves Performance: It significantly enhances the strength and toughness of castings, reduces white mouth tendency, and improves machinability.

Usage Recommendations for FeSi Grain Inoculant

The amount of FeSi grain added should be adjusted based on the type of cast iron and actual production conditions. For gray iron, the recommended addition is 0.2% to 0.5%; for ductile iron, it is 0.5% to 1.1%. In horizontal continuous casting of ductile iron, the addition can be increased from 0.8% to 1.5%. Proper dosage is crucial for achieving optimal inoculation effects.

Specific Applications of Ferrosilicon Grain Inoculant

1. Steel Deoxidation: FeSi grain can effectively remove oxygen during steelmaking, shortening the deoxidation time and saving energy.
2. Iron Casting Production: As an inoculant and spheroidizing agent, ferrosilicon grain significantly improves the microstructure of cast iron, enhancing its mechanical properties.
3. Cost Control: Compared to expensive inoculants and spheroidizing agents, ferrosilicon grain can effectively reduce production costs and improve economic efficiency.

Special Specifications of FeSi Grain Inoculant

We offer various granularities of FeSi grain, including 0-1mm, 1-3mm, and 3-8mm, and can customize special specifications according to customer requirements. Additionally, we provide packaging options such as 25kg plastic-welded woven bags, with outer ton bags, ensuring convenient transportation and storage.

Quality Assurance for Ferrosilicon Grain Inoculant

Each batch of products undergoes strict quality testing. The packaging bags indicate the product name and quantity and come with detailed quality assurance certificates to ensure that customers receive products that meet standards.

Other Inoculants and Their Applications

In addition to FeSi grain inoculant, LSFerroalloy also provides specialized inoculants such as silicon barium, silicon calcium, and silicon barium calcium. These products perform exceptionally well in different types of iron casting, further optimizing the performance of castings. For example:
Silicon Strontium Inoculant: Highly effective in preventing shrinkage porosity.
Silicon Barium Calcium Inoculant: Strongly increases graphitization nuclei, refines graphite, and improves spheroidization grade, significantly reducing white mouth tendency and enhancing machinability.
