Product Description
Product Overview
High-performance alumina red fire bricks designed specifically for tunnel kiln applications in clay brick manufacturing plants. These refractory materials provide exceptional thermal stability and durability in demanding industrial environments.
Key Features & Benefits
- Outstanding resistance to alkali attack for extended service life
- Excellent thermal-shock resistance with 16+ cycles at 1100°C
- Low thermal conductivity (1.5 W/m.K) for improved energy efficiency
- Reduces kiln shell load and mechanical stress on lining
- High cold crushing strength of 57 MPa for structural integrity
Primary Applications
Specifically engineered for use in:
- Tunnel kilns in clay brick manufacturing plants
- Cement kilns and industrial furnace applications
- Safety zones and pre-heating/calcining zones
- Red clay brick production lines and fired brick operations
