We all know that ceramic fiber is a light and efficient insulation and insulation material. It has great advantages compared to traditional thermal insulation materials. Therefore, it is often used as a furnace lining material in the kiln industry. In addition to the performance of the product itself, there are several main reasons for being selected as ceramic fiber as a furnace lining material:
1. Low volume density: The ceramic fiber lining is more than 75%lined with light insulation brick furnace, and 90%to 95%lighter than the light pouring furnace lining. If the ceramic fiber module furnace lines can greatly reduce the steel structure load of the kiln and extend the life of the furnace body.
2. Low thermal capacity (heat storage capacity): The thermal capacity of ceramic fibers is only about 1/10 of the light heat heat -resistant lining and light pouring lining, and the thermal capacity of the furnace lining material is proportional to the weight of the furnace lining. Low thermal capacity means that the kiln has less calories absorbed in the reciprocating operation, and at the same time, the heating speed is accelerated, which greatly reduces the energy consumption in the furnace temperature operation control. energy saving effect.
3. Low thermal conductivity: When the average temperature of ceramic fiber is 400 ° C, the thermal conductivity coefficient is less than 0.1W/mk, the average 600 ° C is 0.15W/mk, and the average of 1000 ° C is less than 0.25W/mK, which is about lightweight clay bricks. The 1/8 is 1/10 in the light heat -resistant lining, and the insulation effect is significant.
4. Simple construction: There is no need to leave the swelling seam of the construction process. The construction personnel can be on the job after basic training. The construction technical factors have a small impact on the heat of the furnace lining.
5. Excellent resistance to heat shock and mechanical vibration: Fiber blankets and modules are flexible and elastic, and have particularly excellent resistance to severe temperature fluctuations and mechanical vibrations. Under the premise of being able to withstand the heating body, the fiber folding module lining can be heated or cooled at any fast speed and is not easy to damage.
