Product Features

High Strength: Cold crushing strength ranges from 80 to 100 MPa, providing excellent load-bearing capacity in high-stress environments.
Wear Resistance: These bricks are resistant to abrasion, making them ideal for high-wear zones in cement kilns.
Thermal Shock Resistance: Designed to resist thermal cycling with minimal degradation (thermal shock resistance ≥10 for AZM-1550 and ≥20 for AZM-1680).
High Refractoriness: With refractoriness under load (RUL) reaching up to 1680°C, these bricks can withstand extreme temperatures without significant deformation.
Low Porosity: Apparent porosity is kept under 20%, ensuring better insulation and enhanced structural integrity.

Applications

Silica Mullite Bricks are primarily used in high-temperature zones where extreme conditions demand reliable and durable refractory materials. Common applications include:

Cement Kilns: Particularly effective in the transition zone, cooling zone, and rotary kiln outlets.
Rotary Kilns: Ideal for protecting the kiln from wear and thermal shock, especially in the calcining zone.
Smelting Furnaces: Suitable for use in metal smelting, including steel and non-ferrous metal industries.
Glass and Ceramic Industries: Provides superior performance in high-temperature operations.
Power Generation: Used in high-temperature combustion chambers and other critical furnace components.
