M'mafakitale komwe kutentha kwambiri kumakhala kovuta nthawi zonse, kusankha zinthu zotsutsana ndi kutentha kungapangitse kapena kusokoneza magwiridwe antchito, chitetezo, komanso kugwiritsa ntchito bwino ndalama. Chomera cholimba cha alumina chopanda mphamvu Imaonekera ngati mwala wapangodya, wopangidwa kuti upirire kutentha kwambiri, kukokoloka kwa mankhwala, komanso kuwonongeka kwa makina. Kaya mukupanga zitsulo, zoumba, magalasi, kapena gawo lililonse lofunika kulimba kosatha kutentha, matope apaderawa amapereka magwiridwe antchito osayerekezeka omwe njira zina zodziwika bwino sizingafanane nawo. Tiyeni tiwone chifukwa chake matope okhala ndi alumina refractory ambiri ndi chisankho chabwino kwambiri pakugwiritsa ntchito kutentha kwambiri padziko lonse lapansi.
Choyamba, matope opopera alumina okhala ndi alumina wambiri ndi abwino kwambiri pakugwiritsa ntchito zitsulo, gawo lomwe kutentha nthawi zambiri kumakwera pamwamba pa 1500°C. M'mafakitale achitsulo, amagwiritsidwa ntchito kwambiri pomangirira njerwa zopopera mu uvuni wophulika, ma ladle, ma tundishes, ndi ng'anjo zamagetsi. Kuchuluka kwa alumina (nthawi zambiri 70% mpaka 90%) kumapatsa kupopera kwapadera, kuteteza kusungunuka kapena kusinthika ngakhale kutentha kwambiri kwa chitsulo chosungunuka. Kuphatikiza apo, imalimbana ndi dzimbiri kuchokera ku slag yosungunuka, ma oxide achitsulo, ndi zinthu zina zamphamvu zomwe zimapezeka popanga chitsulo. Kulimba kumeneku kumachepetsa nthawi yogwira ntchito chifukwa cha kulephera kwa kupopera, kuonetsetsa kuti ntchito yopitilira ndikuchepetsa ndalama zokonzera opanga zitsulo.
Makampani opanga zinthu zoumba ndi magalasi amadaliranso kwambiri matope amphamvu oletsa alumina. Ma uvuni a ceramic, omwe amagwiritsidwa ntchito poyatsira miphika, matailosi, ndi ziwiya zapamwamba, amagwira ntchito kutentha pakati pa 1200°C ndi 1800°C. Madzi amphamvu oletsa alumina amapereka mgwirizano wolimba komanso wokhazikika pa kutentha kwa ziwiya zoletsa mu ziwiya izi, kusunga umphumphu wa kapangidwe kake ngakhale nthawi yotenthetsera ndi kuzizira mobwerezabwereza. Pa ziwiya zosungunuka ndi magalasi, komwe kutentha kumapitirira 1600°C, kukana kwa matope ku kutentha ndikofunikira kwambiri. Amaletsa ming'alu ndi kuphulika komwe kumachitika chifukwa cha kusinthasintha kwa kutentha mwachangu, kukulitsa nthawi ya moyo wa ziwiya zoumba ndikuwonetsetsa kuti galasi ndi labwino nthawi zonse. Mosiyana ndi ziwiya zochepa zoletsa alumina, sizimachita ndi kusungunuka kwa magalasi, kupewa kuipitsidwa komwe kungawononge magulu a zinthu zagalasi.
Ntchito ina yofunika kwambiri ili m'mafakitale opanga mphamvu zamagetsi ndi kutentha. Mu ma boiler, ma incinerator, ndi ma reformer, alumina wambiri wotsutsa matope amamangirira zinthu zotsutsa zomwe zimakumana ndi kutentha kwambiri, mpweya wotuluka m'madzi, ndi kuukiridwa ndi mankhwala kuchokera ku mafuta ndi zinthu zina. Mumafakitale opanga mphamvu zamagetsi pogwiritsa ntchito malasha, imapirira kuuma kwa phulusa la ntchentche komanso kuwonongeka kwa ma sulfure oxides. Mu ma crackers ndi ma reformer a petrochemical, imalimbana ndi kuwonongeka kwa ma hydrocarbon ndi nthunzi yotentha kwambiri, kuonetsetsa kuti mphamvu imapanga bwino komanso moyenera. Makhalidwe ake abwino ogwirira ntchito amathandizanso kukonza zolumikizira zowonongeka zotsutsa, kuchepetsa nthawi yogwira ntchito komanso kukulitsa moyo wa zida zofunika.
Kupatula mafakitale ofunikira awa, matope oletsa alumina okhala ndi alumina wambiri amagwiritsidwa ntchito m'mafakitale owotcha zinyalala, komwe amasamalira kutentha kwambiri ndi mpweya wowononga womwe umapangidwa chifukwa cha kutentha zinyalala za m'matauni ndi m'mafakitale. Ndiwofunikanso kwambiri m'mafakitale opangira nkhungu ndi zophimba zomwe zimagwiritsidwa ntchito popanga zitsulo. Kusinthasintha kwake, kuphatikiza ndi kukana kutentha kwambiri komanso kulimba, kumapangitsa kuti ikhale yankho lapadziko lonse lapansi pakugwiritsa ntchito kulikonse komwe kumafuna kulumikizana kodalirika m'malo otentha kwambiri.
Posankha matope okhala ndi alumina refractory wochuluka, ndikofunikira kusankha chinthu chapamwamba chomwe chikugwirizana ndi miyezo yamakampani. Yang'anani matope okhala ndi kukula kwa tinthu tosasinthasintha, kumamatira mwamphamvu, komanso kukana kutentha kwambiri. matope athu okhala ndi alumina refractory wochuluka amapangidwa pogwiritsa ntchito zipangizo zapamwamba komanso njira zamakono zopangira, zomwe zimaonetsetsa kuti zikugwira ntchito bwino kwambiri pa ntchito zovuta kwambiri. Kaya mukufuna kuyika ng'anjo yaikulu yachitsulo, kukonza uvuni wa ceramic, kapena kusamalira boiler yamagetsi, matope athu amapereka kudalirika komanso moyo wautali womwe mukufunikira kuti ntchito zanu ziyende bwino.
Musamachepetse mphamvu ya ntchito yanu pankhani ya kutentha kwambiri. Sankhani matope amphamvu oletsa kutentha, oletsa dzimbiri, komanso okhazikika. Lumikizanani nafe lero kuti mudziwe zambiri za zinthu zathu ndi momwe zingakulitsire magwiridwe antchito anu ndikuchepetsa ndalama zokonzera.
