Refractory fiberka mokgwa wa ho fetisa mocheso ka hoo e ka bang arotsoe ka likarolo tse 'maloa, mahlaseli mocheso phetiso ea silo porous, moea ka hare porous silo mocheso conductivity le mogote conductivity ea faeba tiileng, moo convective mocheso phetiso ea moea e hlokomolohuoa. Bongata ba bongata le mocheso li na le kamano e itšetlehileng ka tse ling, ha mocheso o phahame, ho theola boima ba 'mele, tekanyo ea mocheso oa mahlaseli a kotsi ea eketseha. Bakeng sa lihlahisoa tsa fiber ea refractory, bongata ba bongata hangata bo ka tlase ho 0.25g / cm ', porosity e ka holimo ho 90%, karolo ea khase e ka bonoa e tsoela pele, karolo e tiileng e ka bonoa e le e sa khaotseng, kahoo mocheso o tiileng oa mocheso oa fiber ke e nyane haholo.
Haeba feela ho tloha khopolong ea hore bongata bo bongata bo nyane, conductivity ea mocheso e kholo, bongata bo bongata bo boholo ba mocheso oa mocheso o monyenyane; sena se boetse ha se lumellane le boemo ba sebele, joalo ka litaba tsa bolo ea slag li fapane, le haeba boima ba bongata bo lekana, palo ea likhoele ka palo ea yuniti e fapane, e le hore porosity ka unit volume ha e tšoane, kahoo ho tla ba le phapang ho conductivity ea mocheso. Leha ho le joalo, liqeto tsa boleng li ka akaretsoa ka tsela e latelang.
1. The mogote conductivity ealikhoele tse refractorye fokotseha ka ho eketseha ha sekhahla, 'me ho fokotseha ho fokotseha butle-butle, empa ha boima bo fihla moeling o itseng, mocheso oa mocheso ha o sa fokotseha' me o na le tšekamelo ea ho eketseha butle-butle.
2. Ka lithempereichara tse fapaneng, ho na le conductivity e fokolang ea mocheso le tekanyo e fokolang e lumellanang. Boima bo tsamaisanang le bonyane ba mocheso oa mocheso bo eketseha ka mocheso o ntseng o eketseha.
3. Bakeng sa boima bo tšoanang, conductivity ea mocheso e fapana le boholo ba li-pores.
(1) Pore boholo 0.1mm.

(2) Sekoti sa 2mm.
Ho 0C = 0.0314W/(m, K) λ = 0. 0512W/(m. K) ho 100C. K)
Pore ​​bophara ba 1mm, mocheso o phahama ho tloha ho 0C ho ea ho 500C, boleng ba eona ba mocheso oa mocheso bo eketseha ka makhetlo a 5.3; pore bophara ba 5mm, mocheso tsoha ho tloha 0C ho 500C, mogote conductivity boleng lona eketseha ka makhetlo a 11,7. Ka hona, li-pores tse ka har'a fiber ea refractory li kholoanyane, ho fokotseha ha bongata ba bongata bo lekanang, 'me mocheso oa mocheso oa eketseha.
