I-refractory fiber, eyaziwa ngokuba yi-ceramic fiber, okwangoku iyeyona nto inqabileyo ene-conductivity ye-thermal ephantsi kunye neyona nto ingcono yokugquma i-thermal kunye nefuthe lokonga amandla ukongeza kwi-nano-materials.Ineenzuzo ezininzi, ezinjengobunzima obulula, ukumelana nobushushu obuphezulu, isiphumo esihle sokufakelwa kwe-thermal, ukwakhiwa okufanelekileyo, njl.Xa kuthelekiswa nezitena zesiqhelo, izinto zokulahla kunye nezinye izinto, iibhloko zokugoqa ze-ceramic fiber zineenzuzo ezilandelayo zokusebenza:

a) Ubunzima bokukhanya (ukunciphisa umthwalo wesithando somlilo kunye nokwandisa ubomi besithando somlilo): i-fiber refractory luhlobo lwe-fibrous refractory material.Eyona ngubo yefiber ye-refractory esetyenziswa ngokuqhelekileyo inomthamo we-96 ~ 128kg / m3, ngelixa ubuninzi bomthamo wemodyuli ye-fiber refractory ehlanganiswe ngengubo yefiber iphakathi kwe-200 ~ 240kg / m3, kwaye ubunzima buyi-1/5 ~ 1/ I-10 yezitena ezikhanyelayo ezikhanyelayo okanye i-amorphous material, kunye ne-1/15 ~ 1/20 yezinto ezinzima eziphikisayo.Inokubonwa ukuba i-refractory fiber furnace imathiriyeli inokuqonda ukukhanya kunye nokusebenza kakuhle kwesithando somlilo, ukunciphisa umthwalo wesithando somlilo kunye nokwandisa ubomi beziko.

b) Umthamo wobushushu obuphantsi (ukufunxa ubushushu obuncinane kunye nokunyuka kobushushu ngokukhawuleza): Umthamo wobushushu besixhobo somlilo ngokuqhelekileyo ulungelelaniswa nobunzima bomgca wesithando somlilo.Umthamo wokushisa ophantsi kuthetha ukuba isithando somlilo sithatha ubushushu obuncinci ngexesha lokuphinda usebenze, kwaye isantya sokufudumeza sikhawuleza.Umthamo wobushushu wefiber ye-ceramic yi-1/10 kuphela yokukhanya okumelana nobushushu kunye nezitena ezikhanyelayo ezilula, ezinciphisa kakhulu ukusetyenziswa kwamandla kulawulo lomsebenzi wokushisa.Ngokukodwa ukufudumeza isithando somlilo kunye nokusebenza okungapheliyo, kunomphumela obaluleke kakhulu wokonga amandla

c) I-conductivity ephantsi ye-thermal (ilahleko ephantsi yobushushu): xa ubushushu obuphakathi be-ceramic fiber material yi-200C, i-thermal conductivity ingaphantsi kwe-0. 06W / mk, ngaphantsi kwe-0 kwi-400 ° ngokomyinge.I-10W / mk, malunga ne-1/8 ye-amorphous light-resistant material, kunye ne-1/10 yesitena esikhanyayo, ngelixa i-thermal conductivity ye-ceramic fiber material kunye nezinto ezinzima ezinokumelana nomlilo zingahoywa.Ke ngoko, impembelelo yokufakelwa kwe-thermal yezixhobo zefiber refractory ibaluleke kakhulu.

d) Ulwakhiwo olulula (akukho hlangano yokwandiswa efunekayo): abasebenzi bokwakha banokuthatha isithuba emva koqeqesho olusisiseko, kunye nefuthe lezinto zobugcisa bokwakha kwisiphumo sokufakelwa kwe-thermal ye-furnace lining.

e) Uluhlu olubanzi lwesicelo: Ngophuhliso lwemveliso kunye netekhnoloji yokusetyenziswa kwefiber ephikisayo, iimveliso zefiber zeceramic ezichasayo ziye zafumanisa uthotho kunye nokusebenza, kwaye imveliso inokuhlangabezana neemfuno zokusetyenziswa kwamaqondo obushushu ahlukeneyo ukusuka kwi-600 ° C ukuya kwi-1400 ° C. Ukusuka kwinkalo ye-morphology, iye ngokuthe ngcembe yenze iintlobo ngeentlobo zokusetyenzwa kwesibini okanye iimveliso ezinzulu zomqhaphu we-ceramic fiber, ingubo yefiber ye-ceramic, i-fiber fiber blanket, i-fiber fibre evakalelwa kwimodyuli ye-refractory, ibhodi ye-ceramic fiber, i-ceramic fiber profiled, iphepha le-ceramic fiber, i-fiber textiles kunye nezinye iifom.Inokuhlangabezana neemfuno zeziko lamashishini ahlukeneyo kumashishini ahlukeneyo emveliso yefibre ye-ceramic fiber.

f) Ukumelana nokothuka kwe-Thermal: imodyuli yokugoqa ifayibha inokumelana okugqwesileyo nokuguquguquka okukhulu kobushushu.Kwisiseko sokuba izinto ezishushu zinokuthwala, i-fiber folding modyuli ye-furnace lining inokufudunyezwa okanye ipholile nakwesiphi na isantya.

o) Ukuchasana nokunyakaza komatshini (ngokuguquguquka kunye nokuqina): i-fiber blanket okanye i-fiber blanket iguquguqukayo kwaye i-elastic, kwaye akulula ukuba yonakaliswe.I-furnace yonke emva kofakelo ayilula ukuba yonakaliswe xa ichaphazeleka okanye ishukunyiswa kuthutho lwendlela.

h) Akukho ukomisa kwe-oven: ngaphandle kweenkqubo zokomisa i-oven (ezifana nokunyanga, ukomisa, ukubhaka, inkqubo yokumisa i-oven eyinkimbinkimbi kunye namanyathelo okukhusela kwimozulu ebanda), isithando somlilo singasetyenziswa emva kokwakhiwa.

I-1) Ukusebenza kakuhle kokufakwa kwesandi (ukunciphisa ungcoliseko lwengxolo): ibhloko yokugoqa i-ceramic fiber inokunciphisa ingxolo ephezulu-frequency kunye ne-frequency engaphantsi kwe-1000 Hz.Kumaza esandi anezandi ezingaphantsi kwe-300 Hz, isakhono sokugquma isandi siphezulu kunemathiriyeli eqhelekileyo yokugquma isandi, kwaye inokunciphisa kakhulu ungcoliseko lwengxolo.

j) Ikhono elinamandla lokulawula oluzenzekelayo: uvakalelo oluphezulu lwe-thermal ye-ceramic fiber lining inokulungelelanisa ngakumbi kulawulo oluzenzekelayo lwesithando somlilo.

k) Ukuzinza kweekhemikhali: iimpawu zekhemikhali ze-ceramic fibre folding block zizinzile.Ngaphandle kwe-asidi ye-phosphoric, i-hydrofluoric acid kunye ne-alkali eyomeleleyo, ezinye i-acids, i-alkalis, amanzi, i-oyile kunye ne-steam ayichithwanga.
