| Calcium Oxide (CaO) | 10-15% |
| Magnesium Oxide (MgO) | ≤ 3.0% |
| Silicon Dioxide (SiO2) | ≤ 6.0% |
| Sulfur (S) | ≤ 0.50% |
| Phosphorus (P) | ≤ 0.50% |
| Particle Size | 15-50mm |
| Melting Point | Approximately 1365°C |
Key Features & Benefits
- Uniform chemical composition ensures consistent performance
- Low melting point (1365°C) enables fast melting and reduced smelting time
- Fluorine-free formulation prevents corrosion of furnace lining and ladle
- Dense structure provides excellent moisture resistance for easy storage and transport
- Stable phase composition and rapid slag formation reduce steel plant dust pollution
- Free from hydrogen, nitrogen, and carbon impurities for superior steel quality
- Can replace aluminum wire, calcium silicate, silicon aluminum, and calcium aluminate
Application Methods
Usage Guidelines
- Composition can be customized according to user requirements
- Optimal addition timing: after transfer to refining furnace or in batches
- Recommended consumption: 0.8-1.5 kilograms per ton of steel
Compatible Equipment
Suitable for electric furnaces, converters, medium frequency furnaces, and external smelting operations.
Packaging & Storage
Packaging materials and unit weights are customized based on user needs. Products require waterproof, rainproof, and moisture-proof measures during storage and transportation.
Environmental Advantages
Aluminum calcium spheres support green development initiatives by reducing smoke and dust emissions during steelmaking. Deoxidized products float easily and discharge efficiently, while the cost-effective pricing increases overall steelmaking efficiency.
