Bulk Ferro Silicon 72% 10-50mm For Steel Making
High Recovery Rate (92%+): Optimized lump density ensures the material sinks through the slag quickly, putting more silicon into your steel and less into the waste.
Ideal 10-50mm Size for Steelmaking: Precision-screened to provide the perfect surface area for rapid dissolution without the dust loss common in smaller grains.
Low Impurity "Clean" Steel: Strictly controlled Aluminum (<1.5%) and Phosphorus to ensure high-strength steel results with zero gas porosity.
3,000-Ton Monthly Bulk Capacity: We are a high-volume supplier. Our massive inventory ensures your production line never stops due to a shortage.
Real-Time Factory Price: Skip the traders. Get the best FOB Tianjin/Qingdao price per ton directly from our 30-year manufacturing facility.
Product Overview of Ferro Silicon 72% 10-50mm

FAQ
Q: What is the current bulk price of Ferro Silicon 72 per ton in 2026?
A: Prices fluctuate based on raw materials and energy. As a direct factory, we provide real-time quotes to our bulk buyers. Contact us for today's best FOB price.
Q: Why is the 10-50mm size preferred for ladle additions?
A: This size offers the perfect balance: it's heavy enough to sink through the slag but small enough to dissolve quickly (within seconds) in the ladle, ensuring a high silicon recovery rate.
Q: Does ZhenAn support third-party inspections for bulk orders?
A: Absolutely. We welcome SGS, BV, or CCIC inspections at the loading port to verify chemical content and sizing before your shipment sails.
