1. The Science Behind Alumina Silica Bricks
Alumina silica bricks are the cornerstone of modern refractory technology, blending aluminum oxide (Al₂O₃) and silicon dioxide (SiO₂) to create materials that thrive in temperatures up to 1,750°C (3,182°F). Kerui’s engineered bricks deliver:
- Thermal Harmony: Optimal balance between heat resistance and thermal shock tolerance
- Chemical Versatility: Resist both acidic and basic environments
- Structural Integrity: Maintain strength under continuous thermal cycling
2. Types & Performance Showdown
2.1 The Alumina Silica Elite
| Typ | Al₂O₃ Inhalt | Superpower | Maximale Temperatur |
|---|---|---|---|
| Standard-Schamotte | 25-35% | Cost-effective thermal barrier | 1,300°C |
| Hochtonerde | 45-60% | Extreme heat warrior | 1,600°C |
| Super Duty | 60-72% | Heavy industry champion | 1,750°C |
| Isolierung | 30-40% | Energy-saving specialist | 1,200°C |
Keruis KR-AS65 Super Duty Brick rühmt sich 65% Al₂O₃ content with thermal shock resistance >25 cycles – outperforming competitors by 30%.
