Brief Introduction to Low-Cement High-Aluminum Castables

Low-cement high-aluminum castables are a type of refractory material, which is mainly composed of high-aluminum bauxite clinker, corundum, mullite, and other aggregates, as well as binders such as silicate cement and alumina cement. This castable has a low cement content and a high aluminum content, so it has high refractory performance and good fluidity.

Low-cement high-aluminum castables are mainly used for the lining of high-temperature kilns, such as cement kilns, glass kilns, etc., and other places where high-temperature refractory materials are required, such as steel, non-ferrous metals, and other industries. Its advantages include:

1. High refractory performance: Because it contains high-aluminum refractory materials such as high-aluminum bauxite clinker, it has high refractory performance and can withstand the erosion of high-temperature furnace gas.

2. Good fluidity: Due to the addition of an appropriate amount of cement and other binders, the castable has good fluidity and is convenient for construction.

3. Good wear resistance: Because the aggregate particles are coarse, it has good wear resistance and can resist the wear of materials such as slag during use.

4. Good anti-stripping performance: Since the aggregate particles are coarse and uniform, it has good anti-stripping performance and can maintain the stability of the structure during use.

5. Environmentally friendly and pollution-free: Low-cement high-aluminum castables do not contain substances harmful to the human body and the environment and meet environmental protection requirements.

In short, low-cement high-aluminum castables are high-performance, environmentally friendly refractory materials, suitable for various high-temperature furnace linings and other high-temperature environments that require refractory materials.
