Lub ntsiab cua sov hloov nruab nrab ntawm cov ceramic fiber module yog roj, thiab cov porosity ntawm cov ceramic fiber mus txog ntau tshaj 90 feem pua. Cov roj muaj pes tsawg leeg hauv qhov pores ncaj qha cuam tshuam rau thermal conductivity ntawm ceramic fiber. Lub tshav kub hloov ntawm ceramic fiber yog logarithmic nkhaus, thiab thermal conductivity nqi nce sai dua thaum kub siab tshaj 700 degrees.
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.
