Product Description
Calcium Aluminate Refining Slag for Steel Production
Refining slag is an essential additive for deoxidation and desulfurization in steel manufacturing processes. Available in pre-melting, sintering, composite, and electric melting forms, this product offers comprehensive steel purification capabilities while optimizing production costs.
Core Functions
This refining slag provides triple functionality: desulfurization, deoxidation, and submerged arc welding protection for molten steel. It prevents sulfur recovery, stabilizes steel structure, and enhances overall steel quality without generating residual impurities.
Key Advantages
- Optimized chemical composition enables rapid slag formation and reduced smelting time
- Significant power consumption reduction during refining operations
- Extended service life of steel ladle refractory materials
- Superior desulfurization and deoxygenation performance
- Low melting point ensures effective impurity adsorption during argon blowing
- Customizable production and packaging to meet specific user requirements
Technical Specifications
| Component | Percentage |
|---|---|
| CaO (Calcium Oxide) | 45-50% |
| Al2O3 (Aluminum Oxide) | 35-40% |
| MgO (Magnesium Oxide) | ≤ 5% |
| SiO2 (Silicon Dioxide) | ≤ 5% |
| F (Fluorine) | < 1% |
| Particle Size | 0-30mm block shape |
Application Process
Before steelmaking, place the refining slag in the ladle. As molten steel flows into the ladle, intense stirring occurs between the steel and slag. The refining slag rapidly melts into the molten steel, then aggregates and floats. Its strong reducibility provides powerful deoxygenation and desulfurization capabilities, removing oxygen and sulfur impurities with over 85% desulfurization efficiency.
Quality Assurance
Our refining slag contains no impurities such as fluorine, hydrogen, nitrogen, or carbon, ensuring superior steel quality. The product is non-hygroscopic, preventing furnace lining and ladle erosion. Its dense structure facilitates easy transportation and storage, while stable physical phase ensures rapid slag formation and reduced dust pollution in steel mills.
Custom Manufacturing
We offer custom production of metallurgical furnace materials in various specifications and technical indicators to meet specific customer requirements and production conditions.
