FS-3898 Mullite Refractory Bricks Customized Special Shape 3.0g/cm3
Density
Product Description
High Alumina Bricks are alumina-silicate refractory with more than
48% Al2O3 content. High Alumina Bricks are manufactured with
alumina or other raw materials containing higher alumina content
through molding and firing. High Alumina Brick can resist acid slag
erosion resistance because of its neutral refractory property. High
Alumina Bricks have high thermal stability and refractoriness over
1770ºC.
According to different Al2O3 content, High Alumina Bricks can be
classified into Three Grades in China.
- Grade I High Alumina Bricks have more than 75% Al2O3 content.
- Grade II High Alumina Bricks have 60~75% Al2O3 content.
- Grade III High Alumina Bricks have 48~60% Al2O3 content.
Production Advantage
1. High refractoriness.
2. Good spalling resistance and wear resistance.
3. Good corrosion resistance.
4. Good thermal shock resistance.
5. High mechanical strength.
6. High-temperature creep rate is low.
Production Application
These bricks are widely used as the hot face linings on tunnel
kilns and shuttle kilns.
For most high temperature kilns, the kiln car platform is built
using bubble alumina bricks.
In most cases, the bricks are available in shapes such as
rectangular, arch, end arch, key and wedge.
Bricks with tongue and grooves are also available on request.
