RCF Module

CCEWOOL® RCF Module is a modular refractory ceramic fiber lining system manufactured from spun refractory ceramic fiber blankets. The modules are mechanically pre-compressed and folded into block structures during production. Each module is compressed to a designed density and pre-installed with an anchoring system according to furnace lining requirements, allowing direct attachment to anchor studs welded on the furnace steel shell. Once installed, the modules form a continuous high-temperature insulation lining system.

During installation, the modules are further compressed against the furnace shell. When the external restraints are removed, the fibers expand and release stored compression energy, causing adjacent modules to press tightly against each other. This feature compensates for thermal shrinkage during high-temperature operation and significantly improves the overall sealing integrity and structural stability of the furnace lining system.

In addition, the modular design dramatically reduces installation time compared with traditional refractory linings and lowers long-term maintenance costs. As a result, CCEWOOL® RCF Modules are widely used in a variety of high-temperature industrial furnace lining systems.

To meet the requirements of different furnace structures and installation methods, CCEWOOL® RCF Modules are available in multiple structural configurations and also support Fabrication customization. Module dimensions, thickness, density, folding structure, and anchoring systems can all be customized based on furnace lining designs or engineering drawings, enabling optimal compatibility with different industrial furnace configurations and operating conditions.

Module Structure Types

S-Fold Modules
S-Fold modules are formed by continuous wave-like folding of fiber blankets, creating a dense and uniform fiber arrangement. This design provides strong rebound capability, allowing the lining to compensate for thermal shrinkage during furnace operation. It is commonly used in large-area furnace lining applications.
U-Fold Modules
U-Fold modules are formed through U-shaped folding, producing a balanced internal fiber arrangement that improves the structural stability of the module.
L-Shaped Modules
L-shaped modules are derived from U-Fold designs with modified fiber orientation, allowing better adaptation to furnace edges, corners, and structural transition areas.
Stack Modules
Stack modules are manufactured by stacking layers of fiber blankets to form the module structure, providing a more uniform fiber orientation and stable structural performance.
Monolithic Formed Modules
These modules are manufactured using automated forming processes in a single integrated structure without lamination or assembly joints. The continuous internal fiber structure provides high density, excellent structural strength, and long-term stability.
