Advantages of Ceramic Fiber Modules for Tunnel Kiln

After several years of upgrading, most of the tunnel kilns of brick kiln manufacturers that produce red bricks, shale bricks, etc. now use lightweight ceramic fiber modules as furnace lining refractory insulation materials. So what are the benefits and advantages of using ceramic fiber modules as furnace linings in tunnel kilns? Today, Anchor-Tech will introduce to you:

1. Lightweight and energy-saving

Ceramic fiber modules (folding blocks) for tunnel kiln insulation are a relatively lightweight, energy-saving new type of thermal insulation refractory material. The weight is only 1/7 of heavy refractory materials and 1/3 of lightweight insulation bricks. This can not only reduce the load of insulation materials on the steel structure of the kiln, but also extend the service life of the furnace body.

2. Low thermal conductivity

The thermal conductivity of the ceramic fiber module (folded block) is only about 1/10 of that of the lightweight heat-resistant lining and lightweight castable lining, which can save energy by about 30%. It can not only reduce the energy loss of the kiln during operation, but also save more energy and create more profits.

3. Convenient construction

There is no need to reserve expansion joints during the construction process, and the ceramic fiber modules (folding blocks) can expand in all directions.

4. Stable chemical properties

Ceramic fiber modules are neutral and slightly acidic materials. Except for reacting with strong acids and alkalis, they will not be corroded by weak acids, alkalis, water, oil, and steam, and they are not wetted by lead, aluminum, and copper .

5. No need for oven

The furnace lining can be put into use after construction is completed, without the need for furnace baking. Generally, traditional refractory materials need to be baked, and the baking time is long. The tunnel kiln insulation project using ceramic fiber module (folding block) technology has a short baking time and low investment.

6. Good thermal insulation performance

The tunnel kiln using ceramic fiber modules (folding blocks) does not feel hot when touched from the outside. The temperature inside the furnace is generally 850-1400℃, but the temperature outside is only about 35 degrees. This shows how obvious the thermal insulation effect of ceramic fiber modules is.
