High Strength Light Yellow Corundum Mullite Refractory Castable
Description

Corundum mullite castable is a type of refractory castable that contains a combination of corundum (aluminum oxide, Al2O3) and mullite (aluminum silicate, Al6Si2O13) as its primary constituents. This castable is designed to exhibit excellent high-temperature properties, including high strength, thermal shock resistance, and abrasion resistance.

Corundum mullite castables are used for lining the walls, roofs, and floors of industrial furnaces, such as steelmaking furnaces, heat treatment furnaces, and ceramic kilns. They provide excellent thermal insulation and resistance to high temperatures.

Specifications

Features

1. High-temperature resistance: Corundum mullite castables are designed to withstand high temperatures, typically ranging from 1500°C to 1800°C (2732°F to 3272°F). They can maintain their structural integrity and mechanical properties under prolonged exposure to extreme heat.

2. Thermal shock resistance: These castables exhibit excellent resistance to thermal shock, meaning they can withstand rapid temperature changes without cracking or spalling. This property is particularly important in applications where temperature fluctuations are frequent.

3. High mechanical strength: Corundum mullite castables offer high mechanical strength, allowing them to withstand mechanical stresses, vibrations, and abrasion commonly encountered in high-temperature industrial processes.

4. Excellent abrasion resistance: The presence of corundum and mullite in the castable composition contributes to its superior abrasion resistance. It can withstand the erosive effects of solid particles, abrasive materials, and high-velocity gas flows, making it suitable for applications where wear is a concern.

5. Chemical stability: Corundum mullite castables exhibit good resistance to chemical attack from molten metals, slags, and corrosive gases encountered in various industrial processes. They can withstand the corrosive effects of alkalis, acids, and other chemical substances at high temperatures.
