M'mafakitale omwe kutentha kwambiri kumakhala kovuta nthawi zonse, kusankha kwa zinthu zokanira kumatha kupanga kapena kusokoneza magwiridwe antchito, chitetezo, komanso kutsika mtengo. High alumina refractory matope zimadziwikiratu ngati mwala wapangodya, wopangidwa kuti uzitha kupirira kutentha kosalekeza, kukokoloka kwa mankhwala, komanso kuvala kwa makina. Kaya mukupanga zitsulo, zoumba, kupanga magalasi, kapena gawo lililonse lomwe limafuna kulumikizana kosagwira kutentha, matope apaderawa amapereka magwiridwe antchito osayerekezeka omwe njira zina zofananira sizingafanane. Tiyeni tiwone chifukwa chake matope apamwamba a alumina refractory ndiye chisankho chabwino kwambiri pakugwiritsa ntchito kutentha kwambiri padziko lonse lapansi.
Choyamba, matope apamwamba a alumina refractory amapambana muzitsulo zazitsulo, gawo lomwe kutentha kumakwera pamwamba pa 1500 ° C. M'mafakitale achitsulo, amagwiritsidwa ntchito kwambiri pomanga njerwa zomangira m'ng'anjo zophulika, ma ladles, tundishes, ndi ng'anjo zamagetsi zamagetsi. Kuchuluka kwa alumina (nthawi zambiri 70% mpaka 90%) kumapangitsa kuti chitsulocho chisasungunuke, chimalepheretsa kusungunuka kapena kupunduka ngakhale kutentha kwambiri kwachitsulo chosungunuka. Kuphatikiza apo, imalimbana ndi dzimbiri kuchokera ku slag wosungunuka, ma oxides achitsulo, ndi zinthu zina zaukali zomwe zimapezeka pakupanga zitsulo. Kukhazikika uku kumachepetsa nthawi yopumira chifukwa cha kulephera kwa refractory, kuonetsetsa kuti ntchito ikupitilira ndikuchepetsa mtengo wokonza kwa opanga zitsulo.
Mafakitale a ceramic ndi magalasi amadaliranso kwambiri matope apamwamba a alumina refractory. Mng'anjo za ceramic, zomwe zimagwiritsidwa ntchito kuwombera mbiya, matailosi, ndi zoumba zapamwamba, zimagwira ntchito pa kutentha kwapakati pa 1200 ° C ndi 1800 ° C. Tondo la aluminiyamu lalitali limapereka chomangira cholimba, chosasunthika cha kutentha kwa zomangira zomangira mu ng'anjozi, kusunga umphumphu ngakhale pakuwotcha mobwerezabwereza ndi kuzizira. Kwa ng'anjo zosungunula magalasi, komwe kutentha kumapitilira 1600 ° C, kukana kwa matope kutenthedwa ndi kutentha ndikofunikira. Imalepheretsa ming'alu ndi kuphulika komwe kumachitika chifukwa cha kusinthasintha kwa kutentha, kukulitsa moyo wa ng'anjo za ng'anjo ndikuwonetsetsa kuti magalasi ali abwino. Mosiyana ndi matope otsika a aluminiyamu, sichimayankhidwa ndi magalasi osungunuka, kupewa kuipitsidwa komwe kungawononge magulu agalasi.
Ntchito ina yofunika kwambiri ili mumafuta amafuta a petrochemical ndi matenthedwe. M'ma boilers, incinerators, and reformers, high alumina refractory mortar bonds refractory zigawo zomwe zimakumana ndi kutentha kwambiri, mpweya wa flue, ndi kuwukira kwamafuta kuchokera kumafuta ndi zinthu zina. M'mafakitale opangira malasha, imalimbana ndi phulusa la ntchentche komanso kuwononga kwa ma sulfur oxides. M'mafuta opangira mafuta a petrochemical ndi okonzanso, amakana kuwonongeka kwa ma hydrocarboni ndi nthunzi yotentha kwambiri, kuonetsetsa kuti magetsi apangidwa bwino komanso otetezeka. Makhalidwe ake abwino amamatira amapangitsanso kuti ikhale yabwino kukonzanso zomangira zowonongeka zowonongeka, kuchepetsa nthawi yopuma ndikuwonjezera moyo wautumiki wa zipangizo zofunika kwambiri.
Kupitilira mafakitale oyambira awa, matope apamwamba a alumina refractory amapezeka m'mafakitale otenthetsera zinyalala, momwe amawongolera kutentha kwambiri ndi mpweya wowononga wopangidwa ndi kuwotcha zinyalala zamatauni ndi mafakitale. Ndiwofunikanso m'mapangidwe opangira zisankho ndi ma crucible omwe amagwiritsidwa ntchito poponya zitsulo. Kusinthasintha kwake, kuphatikizidwa ndi kukana kutentha kwapamwamba komanso kulimba kwake, kumapangitsa kuti ikhale yankho lachilengedwe pakugwiritsa ntchito kulikonse komwe kumafunikira kulumikizana kodalirika m'malo otentha kwambiri.
Posankha matope apamwamba a alumina refractory, ndikofunikira kusankha chinthu chapamwamba kwambiri chomwe chimakwaniritsa miyezo yamakampani. Yang'anani matope omwe amagawika kachulukidwe kake, kumamatira mwamphamvu, komanso kukana kugwedezeka kwamphamvu kwamafuta. Mtondo wathu wapamwamba wa alumina refractory umapangidwa pogwiritsa ntchito zida zopangira zopangira zapamwamba komanso njira zapamwamba zowongolera, kuwonetsetsa kuti zimagwira ntchito mwapadera pazofunikira kwambiri. Kaya mukufunika kuyatsa ng'anjo yayikulu yachitsulo, kukonza ng'anjo ya ceramic, kapena kukonza chowotchera chamagetsi, matope athu amapereka kudalirika komanso moyo wautali zomwe mukufunikira kuti ntchito zanu ziziyenda bwino.
Osanyengerera pa magwiridwe antchito zikafika pazotentha kwambiri. Sankhani matope apamwamba a alumina okana kutentha kwambiri, kukana kwa dzimbiri, komanso kulimba. Lumikizanani nafe lero kuti mudziwe zambiri zazinthu zathu komanso momwe zingakuthandizireni kuti mugwiritse ntchito bwino komanso kuchepetsa ndalama zokonzera.
