Njerwa Zapamwamba za Alumina (Checker Brick-19 holes)
Kufotokozera kwa Brick High Alumina Checker
Ngati zomwe zili mu Al2O3 ndizoposa 90%, zimatchedwa njerwa ya corundum. Chifukwa cha zinthu zosiyanasiyana, miyezo ya mayiko osiyanasiyana sikugwirizana kwathunthu. Mwachitsanzo, mayiko a ku Ulaya amanena kuti malire otsika a Al2O3 opangidwa ndi aluminiyamu apamwamba kwambiri ndi 42%. Ku China, njerwa zapamwamba za alumina nthawi zambiri zimatanthawuza njerwa zosakanizika zomwe zili ndi Al2O3 yoposa 48%. Amapangidwa makamaka ndi chilengedwe chapamwamba kwambiri cha bauxite, chomwe chili ndi mchere monga diaspore, bomerite, kaolinite, ndi zina zotero. Dongo lofewa kapena theka-lofewa limawonjezeredwa ku klinker yapamwamba ya alumina monga chomangira kuti ayambe kusakaniza ndi kusakaniza, kenako imapangidwa, yowumitsidwa, ndipo pamapeto pake imathamangitsidwa. The refractoriness wa njerwa mkulu aluminiyamu ndi pafupifupi 1770 ℃, ndi katundu kufewetsa kutentha ndi 1420 ℃-1550 ℃. Common mkulu alumina njerwa ndi LZ-80, LZ-75, LZ-65, LZ-55, LZ-48, etc. Iwo makamaka ntchito akalowa kuphulika ng'anjo, otentha kuphulika ng'anjo, ore-kutentha ng'anjo, magetsi ng'anjo denga, kuphulika. ng'anjo, ng'anjo yoyatsira moto ndi ng'anjo yozungulira. Kuphatikiza apo, njerwa zazikulu za alumina zimagwiritsidwanso ntchito kwambiri ngati njerwa zotsegula zosungira kutentha, mapulagi otsanulira, njerwa za nozzle, ndi zina zambiri.
High Alumina Njerwa Parameters
Ndemanga:
Deta iyi ndi yanu basi.
Ngati muli ndi zofunikira zapadera, chonde lemberani.
Kugwiritsa Ntchito Njerwa Yapamwamba ya Alumina Checker
Njerwa Zapamwamba za Alumina Checker zimagwiritsidwa ntchito makamaka mu ng'anjo yoyaka moto ndi ng'anjo zamoto.
Njerwa Zapamwamba za Alumina Checker zimagwiritsidwa ntchito makamaka popangiranso masitovu otentha. Njerwa Zapamwamba za Alumina Checker zokhala ndi mawonekedwe ena ndi mabowo a gridi amakonzedwa mwadongosolo. Kumtunda ndi kumunsi kudzera m'mabowo a njerwa zowunikira amatha kulola gasi kudutsa. Malingana ndi zofunikira zaumisiri zamitundu yosiyanasiyana ya kutentha, njerwa za siliceous cheke, njerwa zadongo, ndi zina zambiri zimagwiritsidwa ntchito. M'zitofu zina zotentha zotentha, njerwa zapamwamba za alumina, njerwa za mullite, njerwa za sillimanite, etc.
Ntchito ya chitofu chowotcha ndikuwotcha mpweya wozizira womwe umatumizidwa ndi wowuzira ku ng'anjo yamoto mu mpweya wotentha, ndiyeno kutumiza mpweya wotentha ku ng'anjo yophulika kudzera muzitsulo zotentha zotentha kuti ziwotche. Chitofu chowotcha ng'anjo yotentha chimakhala ndi nthawi yoyaka ndi nthawi yoperekera mpweya, ndipo nthawi ziwiri zogwirira ntchito zimayenda nthawi ndi nthawi. Panthawi yoyaka moto, mpweya wotentha wotentha kwambiri umadutsa m'mabowo a njerwa za ng'anjo yotentha yotentha ndikutumiza kutentha kwa njerwa zowunikira; pa nthawi yoperekera mpweya, mpweya wozizira wochokera ku mphepo umalowa m'ng'anjo yotentha yotentha ndipo umatenthedwa ndi njerwa za checker mu mpweya wotentha. Kutumizidwa ku ng'anjo yophulika kudzera munjira ya mpweya wotentha.
