Product Description
Low Thermal Conductivity Anti-Stripping Refractory Bricks
Engineered for superior performance in high-temperature industrial applications, these synthetic refractory bricks feature exceptional thermal and chemical resistance properties.
Product Overview
Manufactured using advanced synthetic low-conductivity and thermal-alkali-resistant raw materials including alumina fine powder, andalusite, and bound clay. The production process involves precise mixing, pressing, drying, and firing to achieve optimal performance characteristics.
Key Features
- Outstanding resistance to alkali attack with first-grade performance at 1100°C
- Excellent thermal shock resistance (16 cycles at 1100°C)
- Low thermal conductivity (≤1.5 W/m.K at 700°C)
- Reduces kiln shell load and mechanical stress on lining
- High cold crushing strength (≥45 MPa, typical 57 MPa)
- Superior refractoriness under load (≥1310°C, typical 1330°C)
Applications
- Tunnel kilns for brick production lines
- Cement kilns - safety zone and pre-heating/calcining zones in rotary kilns
- Clay brick plant red clay brick production lines
- Fired brick manufacturing facilities
