High Alumina Refractory Fire Bricks For Ceramic Tunnel Kiln , Iron Making Furnaces Firebrick
Description:
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.
The most competitive price,good quality,safty packing,prompt delivery time,and excellent after-sales services.
Lower ferric Oxide,lower porosity,higher refractoriness,higher density,higher CCS and exact tolerance.
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
