Il-mezz ewlieni tat-trasferiment tas-sħana tal-modulu tal-fibra taċ-ċeramika huwa l-gass, u l-porożità tal-fibra taċ-ċeramika tilħaq aktar minn 90 fil-mija. Il-kompożizzjoni tal-gass fil-pori taffettwa direttament il-konduttività termali tal-fibra taċ-ċeramika. It-trasferiment tas-sħana tal-fibra taċ-ċeramika huwa kurva logaritmika, u l-valur tal-konduttività termali jogħla aktar malajr meta t-temperatura tkun ogħla minn 700 grad.
The steady-state heat transfer of ceramic fiber lining is mainly based on the heat insulation of the furnace wall or heat insulation. The thermal conductivity of refractory fiber is small, and the heat resistance through such a furnace lining is relatively large, and the heat dissipation loss can be significantly reduced. The non-steady state heat transfer of refractory fiber lining is mainly based on reducing the heat storage of the lining. The intermittent heating furnace frequently raises and lowers the temperature, most of the time in the heating furnace wall. Due to the low heat storage of the ceramic fiber lining, the heating and cooling time of the furnace is greatly shortened, and a large part of the heat is saved.
