Great Bulk Density High Alumina Brick For Ceramic Tunnel Kiln And Steel Furnaces
Description:
Laurel high alumina bricks are produced with selected bauxite chamotte by advanced process and strict quality control. The main mineral components are corundum and mullite phases. It features excellent high temperature mechanics and chemical corrosion resistance.
Features
1.Resisting high temperature
2.Great bulk density
3.Low iron content
4.Good eroding resistance
Applications:
1. Steel furnaces
2. Iron making furnaces
3. Glass kiln
4. Ceramic tunnel kiln
5. Cement kiln
