Ceramic Fiber Product

Ceramic Fiber Product

Ceramic fiber product is used in the metallurgical industry, and its application scope is also expanding. The application of ceramic fiber lining in various industrial furnaces can save 20% to 40% energy, and reduce 90% industrial furnace weight and 70% steel structure weight.

At the same time, the application technology of ceramic fiber product has been greatly developed. It can be predicted that if the ceramic fiber product and their application technology are continuously improved and the performance of ceramic fiber lining is tried to be maintained before use, the energy consumption of high-temperature industrial furnace with ceramic fiber lining can be reduced to the right again.

In addition, due to the application of polycrystalline alumina fiber and polycrystalline mullite fiber, the maximum service temperature of ceramic fiber lining has reached 1500-1600 ℃. If the high temperature coating is applied on the ceramic fiber lining, not only the application range of the ceramic fiber lining can be expanded, but also the maximum service temperature of the ceramic fiber lining can be increased to 1800 ℃.

Ceramic Fiber Product

In a high temperature industrial furnace, ceramic fiber linings with different materials and structures will crystallize and sinter in different degrees under the dual effects of fuel combustion products and high temperature. Among these materials, aluminized ceramic fiber lining has the least change and the longest service life.

In terms of lining structure, ceramic fiber blanket or component lining and composite structure lining composed of ceramic fiber blanket and components are the best.

The method of coating high temperature coating on the surface of ceramic fiber lining or setting dense layer between ceramic fiber lining and each layer of fiber can prevent high temperature airflow from entering into the interior of ceramic fiber lining. Therefore, the heat insulation effect of furnace lining can be improved and the service life of furnace lining can be prolonged. The same effect can be achieved by sticking hard ceramic fiberboard or module on the high temperature side of ceramic fiber furnace lining.
