Aluminum Silicate Fiber Modules

Ceramic fiber modules (also known as aluminum silicate fiber modules) are composed of silicon dioxide and aluminum oxide. It does not contain asbestos and uses natural fiber as the main raw material. According to different specifications, the temperature resistance can reach 850℃-1350℃/24 hours. It is a high-refractory thermal insulation material. It is widely used in various industrial kilns and high-temperature environments; especially furnaces, kilns, boilers, and heaters.

What is a ceramic fiber module?

Ceramic fiber modules are pre-formed, rigid insulation components made from high-quality ceramic fibers. These modules are engineered to provide superior thermal insulation and withstand extreme temperatures, making them ideal for various industrial applications. The manufacturing process involves needle-punching the ceramic fibers and bonding them with a high-temperature adhesive, ensuring a strong and durable structure.

Features of aluminum silicate fiber modules

1. Elastic fiber blanket can resist mechanical external forces
2. The elasticity of the fiber blanket can compensate for the deformation of the furnace shell so that there is no gap between the components
3. Due to its lightweight, it absorbs little heat when used as an insulation material.
4. Low thermal conductivity brings a high energy-saving effect.
5. It has the ability to resist any thermal shock.
6. The lining does not need to be dried and cured, so it can be put into use immediately after installation.
7. The anchoring system is away from the hot surface of the component so that the metal anchor is at a relatively low temperature

Installation method of aluminum silicate fiber module

Derust the furnace plate → Weld the module bolts onto the plate → Take out the module → Screw the module guide rod onto the small head of the screw → Put the module through the guide along the center hole and lean it against the furnace plate → Use a special wrench to tighten the nut onto the screw → Unscrew the guide rod → Install other modules in turn → Pull out the central plastic tube of the module → Remove the module strapping belt → Install the next row of folding modules

Installation requirements of aluminum silicate fiber modules

1. The welding and placement of anchor nails should be accurate and the error should be strictly controlled:
2. Install the backing layer first, then construct the fiber module:
3. Install the furnace roof module first and then install the furnace wall:
4. The furnace wall module should be installed from the bottom to the top:
5. The modules are mostly arranged in the same direction, the “soldier row” arrangement. After installing a row of modules, the compensation blanket should be compressed and laid as required:
6. The joints between the roof and the wall and between the walls should be compressed and laid with compensation blankets.
