FeSi 72% and FeSi 75% – Mill Test Certificates and Steel Cleanliness Comparison
FeSi 72% and FeSi 75%, also called Ferro Silicon 72% and Ferro Silicon 75%, are essential ferroalloys widely used in steelmaking, foundry, and cast iron production. Their high silicon content and low impurities make them critical for steel deoxidation, alloying, and improving steel quality. This article focuses on Mill Test Certificates (MTCs) and compares FeSi 72% and FeSi 75% in terms of steel cleanliness, providing technical insight for industrial users and international buyers.
Can a Mill Test Certificate (MTC) Be Provided for FeSi 72% and FeSi 75%?
Yes, ZhenAn Ferro Silicon 72% and 75% are supplied with Mill Test Certificates (MTCs) for every batch, ensuring traceability, quality, and compliance with international standards.
Key Points About MTC for FeSi 72% and 75%:
Chemical Composition Verification
MTCs detail the silicon content, carbon, phosphorus, sulfur, and aluminum levels.
Guarantees that the supplied FeSi 72% or FeSi 75% meets the specifications required for steelmaking and foundry applications.
Standards Compliance
MTCs confirm conformity with ISO, GB, and ASTM standards, giving buyers confidence in material quality and performance.
Ensures suitability for high-quality steel, ductile iron, and alloy castings.
Traceability and Quality Assurance
Each certificate includes batch number, furnace number, and production date.
Facilitates quality audits and documentation for export compliance.
Customer-Specific Requirements
ZhenAn can provide customized MTCs for FeSi 72% and FeSi 75%, including additional test parameters requested by customers.
Having an MTC allows steelmakers and foundries to verify material quality before use, reducing the risk of impurities affecting steel properties or cast iron performance.
How Does FeSi 72% Compare with FeSi 75% in Terms of Steel Cleanliness?
The difference in steel cleanliness between FeSi 72% and FeSi 75% is primarily due to silicon content and impurity levels, which directly influence deoxidation efficiency and inclusion control.
1. Deoxidation Efficiency
FeSi 75% contains ≥75% silicon, allowing faster and more complete removal of dissolved oxygen in molten steel.
FeSi 72%, with ~72% silicon, is slightly less effective, resulting in moderate deoxidation efficiency.
2. Inclusion Control
Using FeSi 75% reduces non-metallic inclusions, improves steel homogeneity, and enhances mechanical properties.
FeSi 72% produces clean steel but may require slightly higher consumption to achieve comparable inclusion control.
3. Impurity Content
Both grades are produced with low carbon, phosphorus, and sulfur, but FeSi 75% generally has tighter impurity control, further enhancing steel cleanliness and quality.
High-purity FeSi 75% is recommended for alloy steels, stainless steels, and high-strength structural steels, where inclusion minimization is critical.
4. Practical Application
FeSi 75% is ideal for high-quality steelmaking processes, including electric arc furnace (EAF) and basic oxygen furnace (BOF) operations.
FeSi 72% is sufficient for standard carbon steels, mild steels, and general foundry applications, balancing performance and cost.
ZhenAn Ferro Silicon 72% and 75% ensure consistent chemical composition and batch-to-batch stability, allowing steelmakers to optimize deoxidation, inclusion control, and overall steel quality.
Additional Considerations for Steelmakers
Particle Size
Fine particles dissolve faster and improve deoxidation efficiency, which can slightly enhance steel cleanliness even for FeSi 72%.
Storage and Handling
Proper storage prevents moisture absorption and contamination, maintaining metallurgical performance.
