Ferroalloy Production
Submerged arc furnace operations demand reductants that maintain lump integrity through the burden column while delivering consistent carbon reactivity. We supply semi-coke and calcined anthracite sized specifically for SAF feeding — controlling fines generation, ash content, and volatile behavior to support stable furnace operation and predictable alloy quality.
業界の課題
- Maintaining furnace permeability as reductant degrades and generates fines in the burden column
- Controlling phosphorus and sulfur transfer from carbon reductant into the ferroalloy product
- Managing specific energy consumption (kWh/t) that increases with high-ash or high-moisture reductants
- Achieving consistent lump size distribution (10-30 mm, 20-60 mm) to prevent channeling and uneven gas flow
- Balancing reductant cost against carbon utilization efficiency and alloy recovery rates
当社のソリューション
- Semi-Coke with FC 82-88%, low S (<0.5%), and controlled VM for consistent SAF reduction of manganese and silicon ores
- CAC (10-30 mm, 20-60 mm lumps) as a high-FC supplementary reductant for FeSi and silicon metal furnaces
- FeSi 72-75% for downstream steelmaking deoxidation — produced with our own carbon materials
- SiMn 65/17 for combined manganese-silicon alloy applications in steel refining
