FAQ
Q:1.What is the difference between Ferrosilicon 75 (FeSi75) and Ferrosilicon 72 (FeSi7
A:The main difference lies in the silicon content. FeSi75 contains approximately 75% silicon, while FeSi72 contains around 72% silicon. Due to its higher silicon content, FeSi75 offers stronger deoxidation performance, higher alloying efficiency, and is commonly used in steelmaking processes that require higher metallurgical quality.
Q:2.What industries commonly use Ferrosilicon 75?
A:Ferrosilicon 75 is widely used in:
Steelmaking Industry
Foundry and Casting Industry
Metallurgical Industry
Ferroalloy Production
Ductile Iron and Gray Iron Manufacturing
Special Steel and Stainless Steel Production
Q:3.Can you provide third-party inspection certificates?
A:Yes. Third-party inspection reports can be provided upon request. We support inspections from internationally recognized organizations such as SGS, BV, CCIC, and other approved testing agencies to ensure product quality and compliance.
Q:4.
What is the minimum order quantity (MOQ)?
A:The MOQ is flexible and can be adjusted according to customer requirements. We support both sample orders for testing and large-volume bulk orders for long-term cooperation.
Q:5.
What is the delivery time for FeSi75 orders?
A:For standard orders, delivery is typically arranged within 7–15 days after order confirmation. For large-volume orders or customized specifications, the delivery schedule can be arranged based on production planning and customer requirements.
Q:6.
How does Ferrosilicon 75 improve steel quality?
A:FeSi75 acts as an efficient deoxidizer during steelmaking. It reduces oxygen content in molten steel, minimizes harmful inclusions, improves steel cleanliness, and enhances the mechanical properties, strength, toughness, and overall performance of the final steel products.
