Ceramic Fiber Board / RCF Board
Product Description
Ceramic fiber board raw material is ceramic fiber bulk fiber, adding small quantity organic and inorganic binders, the production line is full automatic, continuous and highly advanced. Ceramic fiber board has good flatness, precise size, good bending strength, easy cutting, even distribution and excellent insulation effect. Ceramic fiber board is ideal insulation and refractory material for various industrial furnaces.
Typical Features
Low heat capacity, low thermal conductivity
Good bending strength, high rigidity, easy to process and install
Precise size, good flatness
Excellent thermal stability and thermal shock resistance
Typical Application
Metallurgical: Backup insulation, mold insulation.
Non-Ferrous: Tundish and electric tank back up lining.
Ceramics: Furnace hot face lining, fireproof plate
Glass: Bath back up lining
Petrochemical: Furnace hot face lining.
