Ceramic Fiber Module: Structure, Manufacturing Process, and Installation Guide

What Is a Ceramic Fiber Module?

A ceramic fiber module is a high-performance thermal insulation module designed to enhance the overall insulation efficiency of industrial furnace linings. Compared with traditional insulation materials, this type of insulation module offers superior thermal stability, easy installation, and long service life.

Thanks to its excellent chemical stability and resistance to high temperatures, ceramic fiber modules are widely used in industries such as petrochemical processing, metallurgy, power generation, and heat treatment furnaces.

Key Advantages of Ceramic Fiber Modules

Ceramic fiber modules have become the preferred thermal insulation module for high-temperature applications due to the following benefits:

• Excellent chemical stability in harsh environments

• Outstanding thermal insulation performance

• Low heat storage and energy-saving efficiency

• Strong resistance to thermal shock

• Quick and easy installation

• Reduced maintenance costs

These advantages make ceramic fiber modules an ideal solution for modern industrial furnace linings.

Manufacturing Process of Ceramic Fiber Module

There are various methods for producing ceramic fiber modules, but the most common and reliable process includes the following steps:

1. Folding of Ceramic Fiber Blanket

High-quality ceramic fiber needle blankets with a thickness of 20 mm or 25 mm are folded into module form.

• Only the high-temperature heating surface is folded

• This structure improves thermal resistance and durability

2. Pre-Pressing Process

During the manufacturing of the insulation module, the edges (hems) are pre-pressed but not completely compressed.

• This allows for controlled expansion during installation

• Ensures tight sealing between modules

• After shrinkage, the volume density of the ceramic fiber module reaches 190–230 kg/m³ (excluding metal anchorage), providing excellent insulation performance and structural integrity. 

3. Anchorage System Integration

MA and MB type ceramic fiber modules are equipped with embedded anchoring systems and accessories.

• Ensures secure attachment to furnace walls

• Enhances stability under high-temperature conditions

• Simplifies installation and replacement

Before installation:

• The ceramic fiber module should be temporarily fixed using a standard sizing tool or fixture

• This ensures the module maintains its correct shape and dimensions

• Keeps the module tightly aligned with adjacent units

During installation:

• Ensure close contact between modules

• Avoid gaps that could reduce insulation performance

• Follow proper anchoring procedures for long-term stability
