Product Description
Aluminum Slag Metal Deoxygenation Balls
Aluminum slag balls serve as efficient deoxidizers, desulfurizers, and purifiers in steel production processes including converters, electric furnaces, and LF furnace refining. These cost-effective steelmaking auxiliary materials utilize industrial aluminum ash residue, containing 10-40% metallic aluminum and highly active Al2O3 that readily forms calcium aluminate slag systems for superior purification.
Chemical Composition
| Component | Content Range (%) |
|---|---|
| Al (Metallic Aluminum) | 10-40 |
| Al2O3 (Aluminum Oxide) | 45-65 |
| SiO2 (Silicon Dioxide) | 4-8 |
| MgO (Magnesium Oxide) | 1-10 |
Particle Size: 5-50mm (customizable according to customer requirements)
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, reducing refining time and improving yield
- Enhances grain refinement and molten steel fluidity
- Effectively removes harmful inclusions including oxides, sulfides, and nitrides
Steelmaking Applications
Aluminum slag balls prevent casting defects such as nodules, cold shuts, shrinkage holes, and inclusions. They improve casting surface quality while eliminating slag holes, inclusions, and cracks that typically occur when harmful substances remain in molten steel.
Usage Guidelines
Application: Direct addition to LF furnace during converter steelmaking process
Dosage: 5-7kg per ton of steel as refining slag
Customization: Available in various specifications and chemical indicators based on customer requirements
