Reasons for Industrial Preference
- •
Versatility Across Processes: It functions as a deoxidizer, alloying agent, and inoculant (promotes graphite in cast iron) in one material, eliminating the need for multiple additives. This streamlines workflows in steel mills, foundries, and welding facilities. - •
Scalability for Bulk Use: Available in bulk quantities (blocks up to 1 ton, granules for automated feeding), it integrates seamlessly with industrial batch systems, reducing handling time and labor costs. - •
Regulatory Compliance: Low impurity levels (P, S) ensure compliance with international standards (e.g., ASTM A1028 for steel deoxidizers), avoiding penalties and rework due to non-conforming materials.
Enhancements to Manufacturing Processes
- •
Steelmaking Efficiency: As a deoxidizer, it reduces oxygen-related defects (porosity, cracks) by 30–50% compared to low-Si alternatives. Faster deoxidation shortens furnace holding time, increasing daily output by ~15% in large mills. - •
Cast Iron Quality: In inoculation, adding FeSi 75% refines graphite flakes, boosting tensile strength by 20–30% and machinability by 40%. This cuts post-casting machining time, lowering per-part costs. - •
Welding Consistency: For electrodes, FeSi 75% stabilizes arc length and penetration depth, reducing weld defects (e.g., undercutting) by 25%. This minimizes rework, saving 10–15% in labor and material costs per project.
