In modern industrial operations, efficient thermal insulation is essential for energy savings, equipment protection, and long service life. Among various refractory insulation products, Ceramic Fiber Board stands out as one of the most advanced solutions. Manufactured from high-purity alumina-silica ceramic fiber through vacuum forming, Ceramic Fiber Board offers excellent thermal stability, low conductivity, and lightweight strength, making it ideal for demanding high-temperature applications.
Superior Thermal Insulation: The low thermal conductivity of Ceramic Fiber Board minimizes heat transfer, reducing fuel consumption and improving energy efficiency.
High-Temperature Resistance: Available in different grades with classification temperatures ranging from 1260°C to 1430°C, Ceramic Fiber Board maintains structural integrity even in continuous extreme heat.
Low Heat Storage: Unlike dense refractory bricks, Ceramic Fiber Board allows for rapid heating and cooling cycles, which improves productivity.
Excellent Mechanical Strength: Despite being lightweight, Ceramic Fiber Board resists thermal shock, erosion, and mechanical wear in harsh environments.
Chemical Stability: It is resistant to most acids, alkalis, and corrosive atmospheres, ensuring long-term durability.
Easy Machining: Ceramic Fiber Board can be cut and shaped with common tools, enabling flexible installation in complex furnace structures.
The versatility of Ceramic Fiber Board makes it a preferred insulation material across multiple industries:
Steel & Metallurgy: Used for back-up linings, furnace doors, ladle covers, and tundish insulation.
Petrochemical Processing: Applied in reformers, catalytic crackers, and high-temperature processing units.
Ceramics & Glass Industry: Provides stable insulation for kilns, shuttle furnaces, and glass-melting tanks.
Power Generation: Effective in boilers, turbines, and heat-treatment equipment to reduce heat loss.
Non-Ferrous Metals: Reliable insulation for aluminum, copper, and zinc furnaces.
Building & Fire Protection: Used in fireproof panels, walls, and doors for industrial and commercial structures.
Compared with fireclay bricks or castable materials, Ceramic Fiber Board offers significant advantages:
Lightweight structure reduces furnace load
Rapid installation and easy replacement
Shorter heat-up and cool-down times
Improved operational efficiency and energy savings
Extended equipment service life due to reduced thermal stress
