Mbale Yopangira Alumina: Ntchito Zofunika Kwambiri Pakuteteza ndi Kugwira Ntchito Mwachangu Mafakitale

Mu mafakitale, kusweka, kutentha kwambiri, ndi dzimbiri la mankhwala nthawi zambiri zimafupikitsa nthawi ya moyo wa zida ndikulepheretsa magwiridwe antchito.alumina mkati mwa mbale—Yopangidwa ndi Al₂O₃ yoyera kwambiri ndipo imasungunuka pa kutentha kopitilira 1700°C—imathetsa mavuto awa. Ndi kuuma kwa Rockwell kwa 80-90 HRA komanso kukana kukalamba nthawi 266 kuposa chitsulo cha manganese, yakhala chinthu chofunikira kwambiri m'mafakitale ofunikira. Nazi ntchito zake zazikulu komanso chifukwa chake ndi ndalama zanzeru zomwe mabizinesi akufuna kuchepetsa ndalama ndikulimbitsa bata.

1. Ntchito Zapakati pa Mafakitale

Ma alumina lining plates amagwira ntchito bwino m'malo ovuta, zomwe zimapangitsa kuti akhale ofunikira kwambiri m'malo omwe zida zimapirira kukangana kosalekeza, kugwedezeka, kapena kutentha kwambiri. Nazi ntchito zawo zabwino kwambiri:

Makampani Opanga Mphamvu ndi Malasha

Ma conveyor a malasha, ma pulverizer, ndi mapaipi a phulusa louluka m'malo opangira magetsi ndi migodi amakumana ndi kusweka kwakukulu chifukwa cha tinthu ta malasha. Ma liners achitsulo akale amatha pakatha miyezi ingapo, zomwe zimapangitsa kuti nthawi yogwira ntchito ikhale yokwera mtengo. Ma liners a alumina amawonjezera moyo wa zinthu mpaka nthawi 10, zomwe zimapangitsa kuti agwire ntchito kwa zaka zambiri. Kukana kwawo kutentha kwambiri kwa 1700°C kumagwirizananso ndi machitidwe a boiler ndi njira zotulutsira phulusa.

Magawo a Zitsulo, Simenti ndi Migodi

Pakupanga zitsulo, ma alumina liners amateteza ma blast furnace tapholes, ma ladles, ndi mouth converter ku chitsulo chosungunuka ndi slag, zomwe zimapangitsa kuti ntchito ikhale yolimba ndi 50%. Pa mafakitale ndi migodi ya simenti, amamanga ma chutes, ma crushers, ndi ma grinding mills, kuteteza ku kugundana ndi miyala ndi clinker. Mapaipi a migodi okhala ndi alumina amachepetsa kuwonongeka kwambiri, kuteteza kutuluka kwa madzi ndikuwonjezera mphamvu ya ntchito.

Makampani a Mankhwala ndi Magalasi

Makampani opanga mankhwala amadalira alumina liners kuti apange mapampu, zombo zoyatsira, ndi mapaipi omwe amasamalira ma asidi owononga, maziko, ndi matope. Amalimbana ndi sulfuric acid yochuluka ndi zinthu zina zoopsa, kupewa kutuluka kwa madzi ndi kuipitsidwa kwa zinthuzo. Pakupanga magalasi, kukana kwawo kutentha kwa 1600°C kumawapangitsa kukhala abwino kwambiri pa zipilala za uvuni, kusunga zida ndikuwonetsetsa kuti galasi ndi labwino nthawi zonse.

Ntchito Zapadera

Kupatula mafakitale ofunikira, mbale za alumina zoyera kwambiri (99% Al₂O₃) zimagwiritsidwa ntchito mu ma vesti ankhondo osawombera zipolopolo (chitetezo cha Level 3-6) ndi magalimoto okhala ndi zida—kapangidwe kawo kopepuka kamawonjezera chitonthozo popanda kuwononga chitetezo. M'mafakitale opangira maziko, amaika ma chutes ndi ma crucibles, omwe amatha kupirira kusweka kwachitsulo chosungunuka komanso njira zokhazikitsira zinthu.
