The application effect of ceramic fiber module has been tested by the market. Its advantages are mainly reflected in the following aspects:
1. Light weight.
The density is only 220kg / m3. Taking the heating cover of the bell type furnace as an example, the ceramic fiber furnace lining can reduce the crane tonnage and reduce the plant structure, so as to achieve greater economic benefits.
2. Resistance to mechanical and thermal vibration.
Ceramic fiber lining has certain flexibility and elasticity, and the influence of thermal stress can be ignored in use.
3. Good sound insulation.
The microporous structure inside the ceramic fiber has good sound absorption. This feature is undoubtedly popular in a large number of noise sources such as burners and fans.
4. In addition, ceramic fiber also has a series of characteristics, such as low heat storage, low thermal conductivity, high thermal sensitivity, simple construction, no oven drying, energy saving and consumption reduction, easy temperature regulation and so on.
However, there are also several points to pay attention to in the use of ceramic fiber module. The most important is the corrosive furnace atmosphere. Although ceramic fiber is a stable material in chemical composition, it is easy to be eroded because of its large porosity and large specific surface area. Alkali and vanadium are usually contained in furnaces burning heavy oil; In the furnace of steel smelting, there is a large amount of calcium oxide, which can produce low melting point compounds, which can erode the refractory fiber and promote its shrinkage. Iron, nickel, copper and other metal substances can significantly promote the crystallization rate of refractory fiber and accelerate the pulverization of refractory fiber; Moreover, excessive wind speed will erode the fiber surface and even lead to delamination; In addition, the support of all fiber furnace lining should be steel plate or steel structure, and the castable part is not applicable.
