Ceramic Fiber Modules | Furnace Lining Supplier

Name: Ceramic Fiber Module
Brand: ZOUYU

Ceramic Fiber Module - Pre-Engineered Furnace Lining

Product Overview

ZOUYU ceramic fiber modules are pre-engineered insulation units manufactured using the advanced ISOWOOL production process. Each module undergoes precise pre-folding, cutting, and professional compression to ensure consistent quality and optimal performance in high-temperature furnace linings.

The integrated internal metal fasteners and anchor systems allow rapid installation directly to furnace walls, significantly reducing construction time and labor costs compared to traditional brick or castable linings.

Key Features

Low density and low heat capacity for energy-efficient operation
Low thermal conductivity minimizes heat loss
Anti-thermal shock resistance for cycling applications
Excellent gas erosion resistance
Internal metal fasteners for secure, reliable anchoring
ISOWOOL process ensures uniform quality and dimensional accuracy
Quick installation reduces furnace downtime

Applications

Furnace Linings Kiln Insulation Industrial Heating Heat Treatment Furnaces Petrochemical Heaters Ceramic Kilns

FAQ

Frequently Asked Questions

Technical and commercial answers for this product. If your question is not here, our engineers will answer it directly.

What is a ceramic fiber module?

+

A module is a block of folded or stacked ceramic fiber blanket that has been pre-compressed and fitted with an internal metal anchor system. It is welded or bolted to the furnace shell; once the packaging straps are released the module expands to form a tight, joint-free hot-face lining.

Why use modules instead of layered blanket?

+

Modules install far faster because there is no layer-by-layer anchoring, the pre-compression keeps joints sealed as the lining heats, and the folded construction tolerates thermal cycling better than flat-stacked layers. Damaged modules can also be replaced individually.

What anchoring system do you use?

+

Modules use internal metal fasteners in stainless steel or Inconel, selected to match the furnace temperature and atmosphere. The anchor sits inside the module body so it stays cooler than the hot face.

What density and temperature grades are available?

+

Modules are supplied in COM, ST, HP, HA and HZ grades covering classification temperatures from 1100°C to 1430°C and continuous working temperatures from 1000°C to 1350°C. Density ranges from 60 to 250 kg/m³ depending on grade.

What thermal conductivity should I design to?

+

At 600°C mean temperature, thermal conductivity is typically 0.10-0.20 W/m·K depending on density and grade. Send us your hot-face and cold-face temperatures and we will return a thickness calculation.
