The ceramic fiber module is a needle felt blanket folded and compressed. It is the most commonly used thermal insulation module for low and medium temperature industrial furnaces. The anchor system in the product can be connected to the furnace shell and squeezed tightly to form a seamless gap. Furnace lining as a whole. And the installation method is simple, which greatly speeds up the construction of the furnace lining. With the exception of hydrofluoric acid, and strong bases, the product is not attacked by most other chemicals.
Low volume density
Low volume density: ceramic fiber lining is more than 75% lighter than light insulation brick lining, and 90% to 95% lighter than light castable lining. If the fiber lining is used, the load of the steel structure of the kiln can be greatly reduced, and the service life of the furnace body can be prolonged.
Low heat capacity (heat storage): The heat capacity of ceramic fiber is only about 1/10 of the light-weight heat-resistant lining and light-weight castable lining, and the heat capacity of the lining material is proportional to the weight of the lining. Low heat capacity means that the kiln absorbs less heat during the reciprocating operation, and at the same time accelerates the temperature increase, which greatly reduces the energy consumption in the furnace temperature operation control, especially for the start and stop of the heating furnace. effect.
When the average temperature of the ceramic fiber lining is 400 ºC, the thermal conductivity is less than 0.1w / mk, when the average temperature is 600 ºC, it is less than 0.15 / w / mk, and when the average temperature is 1000 ºC, it is less than 0.25w / mk, about 1/8 of the light clay brick , 1/10 of the light weight heat-resistant lining, the heat insulation effect is remarkable.
Excellent resistance to thermal shock and mechanical vibration: fiber blankets and modules are flexible and elastic, and Liu's severe temperature fluctuations and mechanical vibration have particularly excellent resistance. Under the premise that the heated body can bear, the fiber folding module lining can be heated or cooled at any fast speed without
Simple construction: no expansion joints need to be left in the construction process, the construction personnel can go to work after basic training, and the construction technical factors have little influence on the insulation effect of the furnace lining.
