In high-temperature industrial furnaces and heat treatment equipment, linings must not only withstand continuous thermal radiation but also resist furnace pressure fluctuations and hot gas erosion. If compressive strength is insufficient, boards may collapse, crack, or fail during long-term operation, directly compromising insulation performance and operational safety. Therefore, compressive strength has become a key indicator in evaluating whether ceramic fiber boards can ensure long-term stability.
CCEWOOL® ceramic fiber board maintains a compressive strength of 0.3 MPa even at high temperatures, thanks to continuous optimization of its manufacturing processes:
High-purity raw materials: Selected alumina and silica with impurity levels below 1% reduce the risk of brittle fracture and enhance fiber toughness and strength.
Vacuum forming process: Ensures more uniform fiber distribution and controlled porosity, allowing the board to retain a stable structure under high-temperature compression.
High-temperature sintering reinforcement: Precisely controlled sintering strengthens bonding between fibers, improving overall load-bearing capacity.
Intelligent process optimization: The self-developed “Big Data-Driven Refractory Fiber Process Parameter Optimization System V1.0 ” enables real-time parameter control, ensuring uniform fiber distribution and layer bonding. This further enhances product consistency and compressive performance under extreme conditions.
Thanks to these advanced processes, CCEWOOL® ceramic fiber board maintains long-term structural stability under high temperatures:
Prevents collapse in furnace walls and roofs, extending lining lifespan.
Resists furnace pressure impact in backup layers, preventing structural loosening.
Maintains precise fit in complex equipment areas, reducing maintenance frequency and lowering repair costs.

In industrial furnace lining systems, dimensional accuracy directly determines sealing performance and structural stability. Especially in demanding environments such as steel, aluminum, and heat-treatment furnaces, even a deviation greater than ±1 mm can lead to misalignment, uneven expansion joints, thermal leakage, or even furnace deformation. Therefore, whether an Insulating Fire Brick can maintain high dimensional […]

In high-temperature industrial operations, thermal stability is the most critical indicator to evaluate whether an insulation material can operate safely over the long term. When furnace temperatures fluctuate from several hundred degrees to over 1200°C, any material that shrinks, powderizes, or collapses will cause heat leakage, lining damage, and unplanned shutdown risks. Therefore, only a […]
