Aluminate refractory cement: a solid barrier in high temperature environments

Aluminate refractory cement, also known as high-alumina cement, is a hydraulic cementitious material with excellent performance in high-temperature environments. It is mainly made of high-quality bauxite and lime as raw materials, sintered and ground, with calcium aluminate as the main component. The refractoriness of aluminate refractory cement is not less than 1580 degrees Celsius, and it is usually used for linings of various high-temperature industrial kilns.

Classification of aluminate refractory cement

According to its composition and use, aluminate refractory cement is mainly divided into the following types:

1. Aluminate refractory cement

Aluminate refractory cement, also known as high-alumina cement, is the most commonly used high-temperature refractory cement. It is mainly made of bauxite and limestone through calcination and grinding, and contains calcium aluminate (CaO·Al2O3) and other aluminates. This cement is widely used in the lining of industrial kilns, especially for the masonry of special-shaped furnace bodies.

2. Low calcium aluminate refractory cement

Low calcium aluminate refractory cement is made from high quality bauxite and limestone through sintering and fine grinding. Compared with high alumina cement, it has lower calcium oxide content and higher refractoriness. Its main use is to prepare refractory concrete for lining of high temperature industrial kilns.

3. Calcium magnesium aluminate cement

Calcium magnesium aluminate cement is made by mixing bauxite and dolomite in proportion, sintering and grinding. This cement has the advantages of resistance to chemical corrosion of slag and molten metal, low porosity and small calcination shrinkage, and is widely used as lining material for cement rotary kilns and other industrial kilns.

Application of aluminate refractory cement

Aluminate refractory cement is widely used in the following fields due to its superior performance and stability:

• Power industry: high temperature boiler and waste incinerator lining.
• Metallurgical industry: high temperature furnace and steelmaking furnace lining.
• Petrochemical industry: cracking furnace and gasifier lining.
• Building materials industry: cement kiln lining.

Summarize

Aluminate refractory cement plays a vital role in high-temperature industrial kilns due to its excellent high-temperature refractory performance and wide range of applications. Its diverse product types and superior properties make it the only choice in high-temperature environments.
