Thermal conductivity refers to the heat transferred through an area of 1 square meter in 1 hour for a 1m thick material with a temperature difference of 1 degree (K/°C) on both sides of the material. The unit is watt/meter. Degree (W/(m·K), K can be replaced by ℃).
The thermal conductivity of ceramic fiber products is used to characterize its thermal conductivity.
There are many factors that affect the thermal conductivity of ceramic fiber, which mainly depends on factors such as the structure, bulk density, temperature, pressure, ambient atmosphere and humidity of ceramic fiber products. The relationship between the thermal conductivity between the
module and the blanket. The bulk density of the
ceramic fiber blanket and the ceramic fiber module is very different. The bulk density of the blanket is 96Kg/m³ and 128Kg/m², and the bulk density of the ceramic fiber module is 220Kg/m³. Both are lightweight refractory fiber products with low thermal conductivity and good heat insulation effect. From the technical indicators of ceramic fiber modules and blankets, it can be seen that there is not much difference in thermal conductivity between the two.
However, in the thermal calculation of industrial furnace applications, the thermal conductivity of the ceramic fiber module is calculated based on 1.3 times the thermal conductivity of the blanket. This is because when ceramic fiber modules are used as industrial furnace linings, they are fixed on the metal furnace shell with the help of high-temperature metal anchors. The thermal conductivity coefficient at different temperatures is calculated based on the data collected from the domestic application of ceramic fiber products for many years. Formulas and coefficients between thermal conductivity of ceramic fiber modules and blankets.
