Low Grade Ferro Silicon Lumps Si 50-65
Product Description
In steelmaking and casting, not all processes require high-purity Ferro Silicon. Our Low Grade Ferro Silicon Lumps (Si 50-65%) serve as the perfect "Economical Deoxidizer". It retains sufficient silicon activity to effectively remove oxygen from molten steel while drastically reducing your alloying costs. Our products are strictly compacted with high density, resistant to powdering, ideal for budget-conscious buyers seeking stability.
Chemical Composition
Si: 50% - 65% (Customizable to specific grades like 55%, 60%)
Al: ≤ 2.0% (Depending on Si grade)
C: ≤ 2.0%
P: ≤ 0.05%
S: ≤ 0.03%
Fe: Balance
Size Specifications
Standard Size: 10-50mm (Lump shape, suitable for direct charging into furnace)
Customizable: Available in 20-80mm or smaller granules upon request.
Low Dust: Optimized compaction process ensures dust rate < 3%, reducing slag cleaning efforts.
Products Description
1.Cost Efficiency: More competitive pricing compared to 75% FeSi, directly reducing per-ton steel cost.
2.Instant Stock & Supply: [See Image: Warehouse Scene] As shown in the photo, our warehouse maintains a large stock of FIBC bags ready for immediate shipment, meeting urgent orders without delay.
3.Ready-to-Use Packaging: Packed in 1-ton FIBC jumbo bags, wear-resistant and waterproof, allowing direct crane loading into the furnace, saving labor costs.
4.Flexible Composition: Customizable Si content (50%-65%) tailored to your specific furnace conditions for optimal metallurgical results.
Applications & Cases
App 1: Ordinary Casting Deoxidation. Used in common carbon steel and low-alloy steel production as an economical deoxidizer.
Case:A Vietnamese foundry replaced part of their 75% FeSi with our 60% Si lumps, reducing per-ton steel cost by approx. $15 without affecting molten steel fluidity.
App 2: FeMnSi Production. Ideal raw material for producing Ferromanganese Silicon, lowering raw material costs.
App 3: EAF Slagging. Adjusting slag basicity to extend furnace lining life.
