1, kutentha kugonjetsedwa ndi nsalu mu madigiri 360 Celsius pansi pa kopitilira muyeso-mkulu kutentha si kuwotcha, si kukalamba;Nsalu zotchingira moto zimatha kupsa ndi moto wotentha kwambiri.
2, nsalu yotchinga moto ikachoka, lawi lamoto limatha kuzimitsidwa lokha;Nsalu yolimbana ndi kutentha kwambiri sidzazimitsa yokha gwero lamoto litachoka pamoto.
3, nsalu yotchinga moto imapangidwa ndi thonje, poliyesitala ndi zida zina;Nsalu yolimbana ndi kutentha kwambiri imapangidwa ndi ulusi wagalasi wapamwamba kwambiri wotumizidwa kunja.
4, kutentha kugonjetsedwa ndi nsalu akhoza kukana dzimbiri pafupifupi zinthu zonse mankhwala, mu asidi amphamvu ndi zinthu zamchere musamakalamba ndi mapindikidwe;Nsalu yotchinga moto ilibe ntchito yotere.
Kutenthetsa kusungunula refractory kumatanthauza porosity yayikulu,Insulating nsaluotsika kachulukidwe voliyumu, otsika matenthedwe madutsidwe wa refractory.Kutenthetsa kusungunula refractory kumatchedwanso light refractories.Zimaphatikizanso zinthu zoletsa kutentha, zopangira ma refractory fiber ndi zinthu za refractory fiber.Insulating nsalu
Kutentha kutchinjiriza refractory amakhala ndi porosity mkulu, zambiri 40% ~ 85%;Kuchuluka kwa voliyumu yotsika, nthawi zambiri zosakwana 1.5g/cm3;Low matenthedwe madutsidwe, kawirikawiri zosakwana 1.0W(m· K).Amagwiritsidwa ntchito ngati zida zotenthetsera zamafakitale, zimatha kuchepetsa kutentha kwa ng'anjo, kupulumutsa mphamvu, komanso kuchepetsa kulemera kwa zida zotentha.Matenthedwe kutchinjiriza refractory mawotchi mphamvu, kuvala kukana ndi kukana kukokoloka slag ndi osauka, sayenera kugwiritsidwa ntchito ponyamula dongosolo ng'anjo ndi kukhudzana mwachindunji ndi slag, mlandu, chitsulo chosungunuka ndi mbali zina.

Kutentha kwapang'onopang'ono zinthu zodzitchinjiriza kumatanthawuza zinthu zotsutsana ndi porosity zosachepera 45%.Pali mitundu yambiri yazinthu zopangira mafuta otsekemera.Njira zazikuluzikulu zamagulu ndi izi:
(1) Malinga ndi kutentha kwautumiki amagawidwa kukhala otsika kutentha kutchinjiriza refractory (utumiki kutentha ndi 600 ~ 900 ° C), sing'anga kutentha kutchinjiriza refractory (utumiki kutentha ndi 900 ~ 1200 ° C) ndi mkulu kutentha kutchinjiriza refractory (utumiki kutentha kwambiri kuposa 1200 ° C).
(2) Malingana ndi kachulukidwe ka voliyumu amagawidwa m'magulu owonetsera kuwala (kuchuluka kwa voliyumu ya 0.4 ~ 1.0g / cm3) ndi zowunikira zotsika kwambiri (kuchuluka kwa voliyumu zosakwana 0.4g / cm3).
(3) Malinga ndi zopangira anawagawa dongo, zotayidwa mkulu, pakachitsulo ndi magnesium kutentha kutchinjiriza zipangizo refractory.
(4) Malinga ndi njira yopangira, imagawidwa kukhala njira yowonjezeramo kutenthedwa, njira ya thovu, njira yamankhwala ndi njira zopangira porous ndi zida zina zopangira matenthedwe.
(5) malinga ndi mawonekedwe a mankhwala lagawidwa zoumbika kutentha kutchinjiriza mankhwala refractory ndi amorphous kutentha kutchinjiriza mankhwala refractory.
Kutentha kwamafuta opangira mafuta opangira matenthedwe ndi zinthu zowuma zowuma ndizosiyana, njira zazikuluzikulu ndikuwonjezera njira, njira ya thovu, njira yama mankhwala ndi njira zopangira porous:
