Iron Silicon Alloy Lumps Durable Raw Material for Ferroalloy Production and Steel Refining
Iron Silicon alloy lumps are robust raw materials serving as the backbone of ferroalloy production and steel refining, thanks to their durability and balanced composition. Comprising iron and silicon (typically 50-70% Si), these lumps withstand harsh processing conditions--high temperatures, mechanical stress--during smelting or refining, ensuring minimal breakdown.
In ferroalloy production, they act as feedstock for manufacturing higher-grade alloys (e.g., FeSi 75), leveraging their silicon content to adjust final alloy ratios efficiently. For steel refining, they function as deoxidizers and alloying agents: added to ladles or furnaces, they remove oxygen and sulfur, refining steel's cleanliness and mechanical properties.
Their durability reduces fines generation during handling, lowering material loss and dust pollution. Compatible with blast furnaces, electric arcs, and ladle furnaces, they support both primary steelmaking and secondary refining. As a cost-effective alternative to pure silicon metal, they balance performance and affordability for producers.
