Why Is CCEWOOL® Ceramic Fiber Board Ideal for Coke Oven Insulation?

Why Is CCEWOOL® Ceramic Fiber Board Ideal for Coke Oven Insulation?

In metallurgical coke oven systems, the coking chamber and regenerator operate continuously at extreme temperatures ranging from 950–1050°C, exposing the structure to sustained thermal loads and mechanical stress. CCEWOOL® refractory ceramic fiber board, known for its low thermal conductivity, high compressive strength, and excellent thermal shock resistance, has become a widely adopted insulation solution in key backing zones—particularly in the coke oven floor and regenerator wall linings.

Superior thermal insulation and load-bearing performance for coke oven floors
Located directly beneath red-hot coke, the oven floor is a highly heat-intensive zone and serves as a key structural base. While traditional composite bricks offer structural support, they often exhibit high thermal conductivity, resulting in increased heat storage losses and reduced thermal efficiency.

CCEWOOL® ceramic fibre board (50mm) delivers significantly lower thermal conductivity, enabling it to minimize heat transfer while reducing insulation thickness and thermal mass. With compressive strength exceeding 0.4 MPa, it reliably supports the upper oven structure without deformation or collapse. Its precision-manufactured dimensions ensure easy on-site installation, reducing construction deviations and alignment issues—making it an ideal material for coke oven floor insulation.

Outstanding thermal shock resistance and dimensional stability in regenerator linings
Regenerator chambers feature intricate structures subject to intense thermal cycling, including hot gas impact, cyclic expansion and contraction, and frequent operational shifts. Conventional lightweight bricks tend to crack, spall, or deform under such harsh conditions.

CCEWOOL® ceramic fiber insulation board is manufactured using high-purity alumina-silica fibers with advanced automated forming and controlled drying processes, creating a dense, uniform fiber matrix that significantly improves resistance to thermal shock. Even under sharp temperature fluctuations, the board maintains geometric stability, helping prevent stress concentrations and delaying crack formation. As a backing layer in regenerator wall systems, it helps preserve the integrity of the refractory lining, extends equipment lifespan, and reduces maintenance costs.

From oven floors to regenerator walls, CCEWOOL® refractory ceramic fiber board provides a lightweight, stable, and energy-efficient solution that enhances the overall performance and reliability of traditional coke oven insulation systems.
