Ceramic Fiber Board: A Full-Spectrum Application Guide for High-Performance Thermal Insulation Materials

I. Thermal Insulation & Lining for High-Temperature Industrial Equipment

1. Metallurgical Industry

• Ladle/teeming ladle back lining: Serves as permanent insulation layers to cut heat loss and extend the service life of shell structures.

• Heating furnace/annealing furnace walls: A substitute for traditional refractory bricks, reducing furnace weight and accelerating temperature rise.

• Continuous casting tundish cover: Resists splashing molten steel at 1300~1500°C and prevents structural deformation.
  
  

2. Petrochemical & Power Industries

• Cracking/reformer furnace lining: Withstands erosion from high-temperature gas flow and allows convenient modular installation.

• Boiler hot-face insulation: Attaches to boiler walls to lower shell surface temperature, with thermal conductivity ranging from only 0.08 to 0.19 W/m·K.

• Flue/stack lining: Features acid corrosion resistance, ideal for SCR denitrification flues.

3. Glass & Ceramic Kilns

• Kiln car surface: Supports fired products and cuts energy consumption from heat storage.

• Kiln observation port baffle: Balances thermal insulation and light transmission; custom cutouts are available on demand.

II. Fire Prevention & Safety Protection

• Fire door core material: Class A1 non-combustible, with zero combustion under flame exposure.

• Cable fire wrapping: Fire barrier partitions for cable trays in data centers and chemical plants.

• Substrate for structural steel fireproof coating: Bonded to steel columns and beams to upgrade fire resistance ratings
  
  

III. Special Industrial Scenarios

Aerospace

• Heat insulation baffles for engine test stands to endure transient high-temperature gas flow.

• Lining for rocket tail flame deflectors.

Electronics Industry

• Heat shields for semiconductor diffusion furnaces and PECVD equipment.

• Carrier plates for lithium battery sintering furnaces to avoid metallic contamination.

IV. Energy Saving & Construction Sectors

• Building fire separation belts: Fire barriers for shafts and elevator hoistways in high-rise buildings.

• Household appliances: Thermal insulation back pads for gas stoves and fireplaces.

V. Other Functional Applications

• High-temperature sealing gaskets: For flange and valve sealing, with pressure resistance ≥1 MPa.

• Laboratory equipment: Lining for muffle furnaces and countertops for high-temperature testing.
  
  

Core Advantages

2. Efficient thermal insulation: Low thermal conductivity drastically reduces heat loss and improves energy efficiency.

3. Lightweight design: Low bulk density eases equipment load and simplifies installation & maintenance.

4. Chemical inertness: Resistant to acid and alkali corrosion (excluding hydrofluoric acid and strong caustic soda), suitable for complex industrial environments.

5. Fire safety compliance: Class A non-combustible material that delivers reliable fire protection.

6. High mechanical strength: Rigid structure with excellent thermal shock resistance, resisting deformation and cracking.

7. Easy machining: Can be cut, drilled and turned into complex custom shapes.
   
   

With technological advancement, its application scope will expand into new energy, intelligent manufacturing and other emerging sectors. Future innovations in material composition and production processes will drive the upgrading of refractory materials and facilitate the development of green industry. Material selection should match working conditions (operating temperature, chemical atmosphere, etc.) to balance performance and cost-effectiveness. Amid growing demand for high-temperature energy conservation, ceramic fiber board has become an indispensable key industrial material.
