Njerwa zamoto za ku China zopangidwa ndi akatswiri odziwa bwino ntchito, zozimitsira moto ...
Potsatira mfundo yoyambira ya "ubwino, thandizo, kuchita bwino ndi kukula", tapeza chidaliro ndi kutamandidwa kuchokera kwa makasitomala am'deralo komanso apadziko lonse lapansi chifukwa chaNjerwa Yaikulu ya Alumina ndi Njerwa Yoyaka Moto ya Andalusite, Timayang'ana kwambiri pakupereka chithandizo kwa makasitomala athu ngati chinthu chofunikira kwambiri pakulimbitsa ubale wathu wa nthawi yayitali. Kupezeka kwathu kosalekeza kwa zinthu zapamwamba komanso mayankho ogwirizana ndi ntchito yathu yabwino kwambiri yogulitsa zinthu zisanagulitsidwe komanso zitagulitsidwa kumatsimikizira mpikisano wamphamvu pamsika wapadziko lonse lapansi.
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.
