Among many other applications across multiple industries, coal dust is used in the manufacturing of refractory bricks. Refractory bricks also have many uses around the world, including open hearth furnaces, electric arc furnaces, metallurgy furnaces, cement rotary kilns, and glass kilns. Coal dust provides the thermal insulation necessary for the refractory bricks to perform as needed.
- Lowers thermal conductivity of final product
- Improves crushing strength and porosity of final product
- Provides thermal shock resistance
- Improves corrosion and heat strength
The coal dust is mixed with water and clay and applied to bricks before firing. The mixture dries for a few hours and is then placed into the kiln for final firing.
