Main introduction of Magnesia-Alumina Spinel Brick:

The Magnesia-Alumina Spinel Brick is made from high purity magnesia sand or fused magnesite and calcined bauxite according to different applications, and then made into different size bricks. The Magnesia-alumina spinel bricks as the chrome free products are specially developed for the transition zone of large scale dry-method cement kiln. They are characterized by high strength, corrosion resistance, high resistance to thermal shock, etc.

Main characters of Manesia-Alumina Spinel Brick:

Low thermal conductivity
High flexibility
Coating friendly
High chemical attack resistance
Low porosity
