features
Fast Reaction Kinetics
Fine-tuned chemistry (68% Si, 18% C) promotes rapid interaction with oxygen, improving process efficiency and shortening refining time.
Low Impurity Control
Strict limits on phosphorus, sulfur, and aluminum help maintain steel cleanliness and consistency for downstream processing.
Improved Cost Efficiency
Dual-function alloy (Si + C) reduces overall alloy consumption and lowers production cost per ton of steel.
Flexible Particle Size
Available in customized sizes (lumps, granules, powder) to match different furnace types and feeding systems.
Stable Quality
Standardized composition and controlled production ensure batch-to-batch consistency for large-scale steel plants.
applications
- Deoxidizer in steelmaking (converter, electric furnace)
- Carbon additive for composition adjustment
- Auxiliary desulfurization and inclusion modification
