Ceramic fiber modules in heat treatment kilns

In order to simplify and speed up the construction of the kiln and improve the integrity of the furnace lining, the new refractory furnace lining products are introduced. The ceramic fiber module is white in color and regular in size, and can be directly fixed on the anchor nail of the steel plate of the industrial kiln shell, which has a good refractory and thermal insulation effect, and improves the integrity of the refractory insulation of the kiln, so it has been widely used in the kiln.

At present, the integral module made of aluminum silicate ceramic fiber blanket compressed is gradually becoming the first refractory material for thermal insulation of modern industrial kiln lining due to its many advantages such as high temperature resistance and easy construction. The wide application of ceramic fiberboard in heat treatment furnaces is mainly due to its following advantages.

1. During the installation process, the folding blanket after unbundling will produce huge stress, and it will be crowded and closed without leaving any gaps;

2. The high elasticity of the fiber blanket can make up for the deformation of the furnace shell and reduce the construction cost. At the same time, it can make up for the gaps caused by different components inside the furnace body due to different thermal changes;

3. Due to the light weight and low heat capacity (only 1/10 of the lightweight heat-resistant lining and lightweight refractory bricks), the energy consumption in the operation and control of furnace temperature can be significantly reduced;

4. The elastic fiber blanket can resist mechanical external force and the ability to resist any thermal shock;

5. Stable chemical properties. Except for phosphoric acid, hydrofluoric acid and strong alkali, other acids, alkalis, water, oil and steam are not eroded.

With the development of refractory fiber production and application technology, refractory ceramic fiber products have been serialized and functionalized, and the products can meet the requirements of different temperature grades from 600 °C to 1400 °C in terms of use temperature. It can also meet the needs of different industrial furnaces in various industries for the use of refractory ceramic fiber products.

Therefore, in terms of form, it has gradually formed a variety of secondary processing or deep processing products from traditional ceramic fiber cotton, ceramic fiber blanket, fiber felt products to refractory fiber modules, ceramic fiber boards, ceramic fiber special-shaped products, ceramic fiber paper, fiber textiles and other forms.
