Metallurgical Function of Ca28Si60
Deoxidation
Silicon acts as a primary deoxidizer, reducing oxygen content in molten steel and improving steel quality.
Compared with high-calcium grades, Ca28Si60 provides:
- More stable reaction behavior
- Lower risk of overreaction
- Better process control
Desulfurization
Calcium reacts with sulfur to form CaS, helping reduce sulfur content.
Ca28Si60 is suitable for:
- Standard desulfurization
- Applications where moderate calcium activity is required
Inclusion Modification
Ca28Si60 is used in aluminum-killed steel to modify alumina inclusions into more stable forms.
This helps:
- Improve steel cleanliness
- Reduce nozzle clogging
- Enhance casting performance
Packaging and Handling
- Moisture-proof inner liner
- Strong export packaging
- Suitable for bulk shipment
Proper storage is recommended to prevent moisture and oxidation.
Quality Control and COA
Each batch is supplied with COA including:
- Chemical composition
- Impurity levels
- Size distribution
Ensuring stable and repeatable performance in steelmaking processes.
Delivery and Supply Capability
- Stable production capacity
- Lead time: 7–15 days
- Flexible delivery arrangements
- Support bulk orders and long-term contracts
We provide consistent supply for continuous steel production.
