Corundum-Zirconia Brick Al2O3 85% ZrO2 8%
Corundum-Zirconia Brick Al2O3 85% ZrO2 8% delivers exceptional resistance to molten steel erosion and slag penetration for steel ladle working linings, slide gate systems, and continuous casting tundish impact areas.
// Key Features
- Exceptional resistance to molten steel and oxidizing slag erosion
- ZrO2 phase toughening enhances fracture toughness and crack resistance
- Low apparent porosity (≤16%) preventing steel and slag infiltration
- High hot strength maintaining structural integrity at 1750°C under metallurgical load
