Our low thermal conductivity anti-stripping bricks are produced using synthetic low-conductivity thermal-alkali-resistant raw materials, alumina fine powder, andalusite, and bound clay. The mixed powder undergoes precise formulation, binding agent addition, pressing, drying, and firing to achieve optimal performance characteristics.
- ISO9001 certified manufacturing with strict quality control throughout production
- Regular third-party inspections of raw materials and finished products
- Comprehensive technical support and after-sales service
- Free samples available for evaluation and testing
Ideal for large and medium-sized hot blast stoves, electric furnace insulation layers, blast furnace gas risers, and cooling fireplace linings in various industrial settings.
