Refractory Ceramic Fiber

Refractory Ceramic Fiber belongs to aluminosilicate fiber, and such fire-proof materials are also called ceramic fiber refractory products, which are featured with light weight, high temperature resistance, good thermal shock resistance, and low thermal conductivity, etc. Such material is commonly used as the ceramic fibre insulation product and the sealing material that is applied in the metallurgical, power, mechanical and chemical industries, and so on.

Refractory Ceramic Fiber Products

Refractory fiber materials are mainly made of ceramic fibre, which can be classified into monocrystalline and docrystalline. And the maximum service temperature of different refractory ceramic fibers varies in different atmosphere. Ceramic fibre, through special process, can be made into fiber board, fiber felt, fiber rope, and fiber blanket, etc.

Refractory Ceramic Fiber Properties

There are different refractory ceramic fibre products, such as the refractory fiber blanket and board, etc. Both of the products have features of the ordinary fiber, such as softness, plasticity, and tensile strength. In addition, they are featured with high temp and erosion resistance, light in weight, good thermal shock resistance, low thermal conductivity and thermal expansion coefficient, lower specific heat, and mechanical vibration resistance, etc. Besides the physical and thermal properties, refractory ceramic fibres are poison free, and durable with longer service lives.

Refractory Ceramic Fiber Uses

Refractory ceramic fiber can be used in the high temperature atmosphere, high pressure and abrading sections, and is taking the places of the insulation bricks, and refractory castable, becoming the preferred materials for the advantages of fire resistance, heat preservation, and sound proof. Applications in different fields are reflected in the following parts:

insulation ceramic fiber


  • The sealing materials used in the furnace door, and the oven curtain;
  • High temperature flue and air duct;
  • Insulation layer of the petrochemical equipment, etc.

Why do we use refractory ceramic fiber?

Energy issue has attracted more and more attentions with the development of industries. On one hand, energy consumption is increasing year by year, and on the other hand, energy efficiency is very low. Statistics show that only 33% of the energy are fully used. But with good thermal and insulation performance, refractory ceramic fiber has becoming the ideal material for energy saving and efficiency increasing. Production practice has proved that the application of refractory fiber in the continuous heating furnace saves energy more than 15%, and used in the intermittent industrial heating furnace saves more than 30%. At the same time, refractory fiber can increase productivity and improve product quality, making the furnace light, large, and good comprehensive performance, etc. So, it is necessary and even a must to use refractory ceramic fiber correctly, to save energy, enhance productivity, reduce cost and make profits.

Attentions For Refractory Ceramic Fiber

Though the advantages above, compared with refractory bricks and high strength castable, the strength of the refractory fiber is lower, so it is commonly used in the insulation layer that directly connect with furnace lining, and various industrial furnaces that are free from particle air flushing.
