Ceramic Fiber Modules

Industrial furnace designers face severe heat loss and anchor failure when using standard loose insulation blankets under continuous high-temperature airflow. Ceramic fiber modules solve this operational challenge. Manufactured by mechanically folding and compressing needle-punched ceramic fiber blankets into dense, monolithic blocks, our modules are pre-assembled with built-in internal anchoring hardware.

With classification temperatures spanning 1260°C to 1600°C and compression densities of 160 to 240 kg/m³, our folded modules provide a seamless, joint-free refractory lining. Because metallic anchors remain on the cold face near the furnace casing shell, they are shielded from direct flame exposure, drastically extending mechanical service life in petrochemical cracking heaters, steel ladle preheaters, and ceramic tunnel kilns.

Standard Module Formats:
- 300 × 300 × (200 / 250 / 300) mm
- 600 × 300 × (200 / 250 / 300) mm
- Custom cut blocks and corner angle L-shapes manufactured per furnace blueprints.
Anchor Configurations:
- Central through-pipe anchor system with rapid stud-welding pins.
- Corner-fixed channel anchors in SS304 (≤ 900°C), SS310 (≤ 1150°C), or Inconel 601 (for sulfur/high-temp atmospheres).

Elimination of Lining Joints: Modules are bound under high lateral compression. Once temporary binding bands are cut during installation, the fiber blankets expand, creating an airtight, joint-free continuous lining.
Cold-Face Anchor Protection: Anchoring clips sit buried within the blanket folds near the cold casing plate, protecting alloy anchors from hot flue gases.
Fast Installation Speed: Stud-welded modular installation installs 3 to 4 times faster than multiple loose blanket layers, shortening plant maintenance shutdowns.
Low Thermal Mass & Energy Savings: Stores minimal sensible heat, enabling fast furnace heat-up and cool-down cycles.
Honest Operating Limitation: Ceramic fiber modules cannot resist direct mechanical abrasion or high-velocity liquid slag washing. In zones with flue gas velocities exceeding 30 m/s or abrasive particulates, coat hot faces with colloidal silica rigidizer or use dense low cement castable.

1. Petrochemical & Refining: Atmospheric/vacuum distillation heaters, ethylene cracking furnace sidewalls, and reformer ceilings.
