Product Introduction
Product Features
1. High Calcium Absorption Rate
The cored wire feeding method enables calcium to react within the molten steel, reducing oxidation and burn-off while ensuring stable utilization.
2. Excellent Deoxidation and Desulfurization
Highly reactive calcium simultaneously reduces oxygen and sulfur content in molten steel, delivering significant refining effects.
3. Noticeable Inclusion Modification
Facilitates conversion of dendritic and angular inclusions into spherical inclusions, enhancing molten steel cleanliness.
4. Stable Reaction and Easy Control
Adjustable feeding speed minimizes impact on furnace conditions, ensuring safer and more reliable on-site operation.
5. Suitable for Late Refining Stages
Feeding during LF, RH, and prior to continuous casting stabilizes molten steel quality.
6. User-Friendly Operation and Cleaner Environment
Reduces dust and spatter, ideal for automated feeding and continuous production.
Primary Applications
- Deoxidation and desulfurization in secondary refining (LF, RH, etc.)
- Modification of molten steel inclusions prior to continuous casting
- Production of steel grades requiring high cleanliness
- Bearing steel, structural steel, and certain alloy steels
Usage Recommendations
- Generally fed during late refining or prior to continuous casting for more stable results.
- Control feeding speed to prevent incomplete calcium reaction from excessive initial feed rates.
- Determine feeding dosage rationally based on steel grade requirements and inclusion control targets.
- Protect from moisture prior to use to prevent degradation of calcium-based materials.
