Silicon Mullite Andalusite Brick

Silicon Mullite Andalusite Brick is designed specifically for the transition zone of cement rotary kilns. It is made from high - purity raw materials such as high - alumina bauxite, SiC, andalusite through high - pressure molding and high - temperature firing. Its unique mullite crystal structure significantly improves erosion resistance, and the addition of andalusite optimizes thermal stability.

Features and Performance

1. High-temperature Resistance: The load - softening temperature is as high as 1650℃, adapting to extreme high - temperature environments.
2. Mechanical Strength: Cold compressive strength≥95MPa, wear - resistant and resistant to spalling.
3. Thermal Insulation and Energy - saving: Low thermal conductivity can reduce the kiln body temperature and energy consumption.
4. Environmental Safety: Chromium - ion free, meeting the requirements of sustainable development.
5. Long - lasting Durability: Low porosity, forming a protective layer during use, with a lifespan of up to 3 years and 2 major overhauls.
