| Main uses |
Iron ore reduction, alloying in pig iron production |
Key Features
- Strong structure: Withstands harsh furnace environments without excessive fines generation
- Balanced Si level: Effective for both chemical reduction of iron oxides and subsequent alloy adjustment
- Metallic grey appearance: Indicates proper reduction and low oxide surface contamination
Benefits in Ironmaking
- Acts as a reducing agent in direct reduction processes, aiding conversion of Fe₂O₃ to metallic iron
- Supplies silicon during pig iron alloying, modifying fluidity and castability
- Supports consistent chemistry in large-scale blast furnace or rotary hearth furnace operations
Applications
- Direct reduction iron (DRI) processes
- Alloying in foundry pig iron for machinability control
- Pre-alloying step in specialty iron production
