Njerwa Yopanda Aluminiyamu Yaikulu ya H22, Njerwa Yotentha Kwambiri ya Moto ya Ng'anjo Yamakampani
Bizinesi yathu ikulonjeza ogwiritsa ntchito onse zinthu zapamwamba komanso kampani yokhutiritsa kwambiri yogulitsa pambuyo pogulitsa. Tikulandira ndi manja awiri makasitomala athu atsopano komanso okhazikika kuti adzakhale nafe.Njerwa Yopanda Aluminiyamu YaikuluGulu lathu lodziwa bwino ntchito za uinjiniya nthawi zambiri limakhala lokonzeka kukuthandizani kuti mukambirane ndikupereka mayankho. Takwanitsanso kukubweretserani zitsanzo zaulere kuti zikwaniritse zosowa zanu. Tingachite bwino kwambiri kuti tikupatseni ntchito yabwino kwambiri, zinthu ndi mayankho. Kwa aliyense amene ali ndi chidwi ndi kampani yathu, muyenera kulumikizana nafe potitumizira maimelo kapena kutilankhulana nafe nthawi yomweyo. Kuti mudziwe mayankho ndi kayendetsedwe kathu, mutha kubwera ku fakitale yathu kuti mudziwe. Nthawi zambiri timalandira alendo ochokera padziko lonse lapansi ku kampani yathu. Pangani ubale wamalonda ang'onoang'ono ndi ife. Simuyenera kuda nkhawa kuti mulankhule nafe za bizinesi. Ndipo tikukhulupirira kuti titha kugawana chidziwitso chabwino kwambiri chamalonda ndi amalonda athu onse.
Njerwa zofewa kwambiri za aluminaNdi mtundu wa zinthu zotsutsana ndi aluminiyamu zomwe zili ndi alumina ngati gawo lalikulu. Ndi kuchuluka kwa alumina kopitilira 48%, zimagawidwa ngati zinthu zotsutsana ndi utsi, zopangidwa kuchokera ku bauxite kapena zinthu zina zopangira zomwe zili ndi alumina yambiri kudzera mu umba ndi calcination.
Gulu:
Kutengera ndi kuchuluka kwa alumina, amagawidwa m'magulu atatu:
Giredi 1: njerwa zokhala ndi aluminiyamu yambiri (Al₂O₃ yokwanira > 75%)
Giredi 2: njerwa zokhala ndi aluminiyamu yambiri (Al₂O₃ zili: 60%~75%)
Giredi 3: njerwa zokhala ndi aluminiyamu wambiri (Al₂O₃ zili: 48%~60%)
Mawonekedwe a Njerwa ndi Zosankha Zapadera:
Njerwa zokhazikika, njerwa za wedge, njerwa zoyang'ana, njerwa zokhotakhota, njerwa zokhazikika, njerwa za arch, njerwa za octagonal, njerwa zoponyera, ndi mawonekedwe apadera malinga ndi zojambula/zitsanzo za kasitomala.
Katundu wa Fizikiki:
1. Kusaya kuyamwa kwa mpweya
Imatha kupirira kutentha kwambiri kuposa 1770℃, nthawi zambiri kuyambira 1750℃ mpaka 1790℃. Kukana kwa alumina kumawonjezeka pamene kuchuluka kwa alumina kumawonjezeka.
2. Kutentha Kofewetsa Katundu
Kawirikawiri imakhala 1420℃ ~ 1530℃. Chifukwa cha kuchuluka kwa alumina, kuchuluka kochepa kwa zinthu zodetsedwa komanso kapangidwe kochepa ka galasi losungunuka, kutentha kwake kofewetsa katundu kumakhala kokwera kuposa kwa njerwa zadothi.
3. Mphamvu Yozizira Yopondereza
Mphamvu yozizira yopondereza ya njerwa za alumina zapamwamba za Giredi 1 (LZ-80) ndi ≥ 70 MPa, pomwe ya njerwa za alumina zapamwamba za Giredi 3 (LZ-48) ndi ≥ 40 MPa.
4. Kukana Kutaya Madzi
Njerwa zokhala ndi aluminiyamu yambiri zimakhala ngati zinthu zosalimba, zomwe zimatha kupirira kuwonongeka kwa zinthu zokhala ndi asidi komanso zamchere, koma kukana kwawo zinthu zokhala ndi asidi n'kofooka kuposa zinthu zokhala ndi asidi.
5. Kuoneka ngati Porosity
Kuchuluka kwa ma porosity a njerwa za alumina zapamwamba za Giredi 1 ndi ≤ 21%, ndipo kwa njerwa za alumina zapamwamba za Giredi 3 ndi ≤ 22%.

Njerwa zapamwamba za aluminaamagwiritsidwa ntchito makamaka pa VOD, AOD, ng'anjo zophulika, ng'anjo zotentha zophulika, EAF, ng'anjo zozungulira, ndi zipilala za uvuni wozungulira. Kuphatikiza apo, njerwa zazitali za alumina zimagwiritsidwanso ntchito kwambiri ngati njerwa zosungiramo kutentha zotseguka, mapulagi ogwiritsira ntchito makina othira, njerwa zolumikizira, ndi zina zotero.
Mafunso Ofunsidwa Kawirikawiri
Mukufuna thandizo? Onetsetsani kuti mwapita ku malo athu othandizira kuti mupeze mayankho a mafunso anu!
Ndife opanga enieni, fakitale yathu yakhala ikupanga zinthu zotsutsa kwa zaka zoposa 30. Tikulonjeza kupereka mtengo wabwino kwambiri, ntchito yabwino kwambiri yogulitsa zinthu zisanagulitsidwe komanso zitagulitsidwa.
Pa njira iliyonse yopangira, RBT ili ndi dongosolo lathunthu la QC la kapangidwe ka mankhwala ndi mawonekedwe ake. Ndipo tidzayesa katunduyo, ndipo satifiketi yaubwino idzatumizidwa ndi katunduyo. Ngati muli ndi zofunikira zapadera, tidzayesetsa momwe tingathere kuti zigwirizane nazo.
Kutengera kuchuluka kwa katundu, nthawi yathu yotumizira ndi yosiyana. Koma tikulonjeza kutumiza mwachangu momwe tingathere ndi mtundu wotsimikizika.
Inde, timapereka zitsanzo zaulere.
Inde, ndithudi, mwalandiridwa kupita ku kampani ya RBT ndi zinthu zathu.
Palibe malire, titha kupereka malingaliro abwino kwambiri komanso yankho malinga ndi momwe zinthu zilili.
Takhala tikupanga zinthu zopinga kwa zaka zoposa 30, tili ndi chithandizo champhamvu chaukadaulo komanso chidziwitso chambiri, titha kuthandiza makasitomala kupanga ma uvuni osiyanasiyana ndikupereka chithandizo chimodzi chokha.
