Product Description
Aluminum Ash Slag Steelmaking Deoxygenation Ball
Aluminum ash balls serve as efficient deoxidizers, desulfurizers, and purifiers in steelmaking processes including converters, electric furnaces, and ladle refining. These cost-effective steelmaking auxiliary materials utilize industrial residue aluminum ash containing 10-40% metallic aluminum and 45-65% highly active aluminum dioxide.
Chemical Composition & Specifications
| Component | Content Range (%) |
|---|---|
| Aluminum (Al) | 10-40 |
| Aluminum Oxide (Al2O3) | 45-65 |
| Silicon Dioxide (SiO2) | 4-8 |
| Magnesium Oxide (MgO) | 1-10 |
| Particle Size | 5-50mm (customizable) |
Key Performance Characteristics
- Excellent desulfurization and deoxygenation capabilities with desulfurization rates exceeding 30% in steelmaking and over 70% in LF refining furnaces
- Rapid production of white slag for efficient refining
- Uniform composition ensures fast dissolution and shorter refining times
- Enhanced yield and improved production efficiency
Steelmaking Process Benefits
- Refines grain size and enhances molten steel fluidity
- Prevents casting defects including nodules, cold shuts, and shrinkage holes
- Effectively removes metal and non-metallic inclusions (oxides, sulfides, nitrides)
- Eliminates casting defects such as slag holes, inclusions, and cracks
Application & Usage
Direct addition to LF furnaces during converter steelmaking processes as refining slag at 5-7kg per ton of steel. Custom specifications and metallurgical furnace materials available upon request.
