Makampani opanga zitsulo amayimira msana wa zomangamanga padziko lonse lapansi, komabe amagwira ntchito m'malo amodzi owopsa kwambiri padziko lapansi. Kuchokera pakutentha kwambiri kwachitsulo chosungunula mpaka kuponyedwa bwino kwachitsulo, zida zofunika kwambiri monga zosinthira, ng'anjo zamagetsi zamagetsi, ndi ng'anjo zophulika zimakumana ndi kupsinjika kosalekeza: ziyenera kupirira kutentha kosalekeza komwe nthawi zambiri kumadutsa 1,600 ° C, kuphatikizidwa ndi kukokoloka koopsa kuchokera ku slag yosungunuka ndi scalding zitsulo. Mikhalidwe yovutayi imapangitsa kuti pakhale zofunikira zosayerekezeka pazinthu zodzitchinjiriza - zigawo zoteteza zomwe zimateteza zida kuti zisawonongeke - komanso pakati pa zosankha zonse,njerwa za magnesium-chromiumtulukani ngati yankho lomaliza, lodalirika ...
Njerwa za Magnesium-chromium zili ndi udindo wawo wosayerekezeka m'makampani azitsulo kuzinthu zitatu zazikulu, zosagonjetseka zomwe zimathetsa ululu uliwonse waukulu wakupanga zitsulo zotentha kwambiri. Choyamba, kukana kwawo kwapadera kwa moto ndikusintha masewera kuti atetezeke ndi kuchita bwino: ndi chiwerengero cha refractoriness pamwamba pa 1,700 ° C, njerwazi zimasunga kukhulupirika kwawo ngakhale muzitsulo zotentha kwambiri za ng'anjo zazitsulo. Mosiyana ndi zida zomangira zocheperako zomwe zimatha kufewetsa kapena kusungunuka pakatentha kwambiri, njerwa za magnesium-chromium zimachotsa chiwopsezo cha kuwonongeka kwa zida mwadzidzidzi, zomwe zimatha kuyimitsa mizere yopangira ndikupangitsa kuti zichedwetsedwe. Chachiwiri, kukana kwawo kwakukulu kwa slag kumalimbana mwachindunji ndi chimodzi mwazovuta zazikulu zamakampani opanga zitsulo. Njerwazi zimapangidwa ndi magnesium oxide ndi chromium oxide, zomwe zimakhala zotchinga zowundana, zosatha kulowa mkati, zomwe zimathamangitsa ma slags amchere komanso acidic - zinthu zambiri zopangidwa ndi chitsulo zomwe zimadya zomangira wamba. Kukana kumeneku kumakulitsa kwambiri moyo wa ng'anjo ndi 30% kapena kupitilira apo poyerekeza ndi zokanira wamba, kuchepetsa ndalama zosinthira pafupipafupi ndikuchepetsa nthawi yosakonzekera. Chachitatu, kukhazikika kwawo kwamphamvu kwamatenthedwe kumatsimikizira kusasinthika panthawi yovuta kwambiri yogwira ntchito. Ng'anjo zikayamba kapena kuzimitsidwa, kutentha kumatha kutsika ndi madigiri mazanamazana m'kanthawi kochepa, zomwe zimapangitsa njerwa zambiri kung'ambika kapena kuphulika. Njerwa za Magnesium-chromium, komabe, zimayamwa kusinthasintha kumeneku mosavutikira, kumapangitsa kuti zitsulo zisamayende bwino ndi kupanga bwino popanda zosokoneza.
Zodziwika bwino izi zimapangitsa njerwa za magnesium-chromium kukhala zofunika kwambiri pagawo lililonse lopangira zitsulo, kuyambira pakukonza zinthu mpaka kuponya komaliza. M'malo osinthira ndi ng'anjo yamagetsi yamagetsi, pomwe zitsulo zimasungunuka ndikuyengedwa, njerwa zimayika makoma amkati, kupirira kukwapula kwachindunji kuchokera pakugwetsa chitsulo chosungunula ndi zowononga. Chitetezo ichi chimalola ng'anjo kugwira ntchito bwino kwambiri kwa nthawi yayitali, kukulitsa kutulutsa kwachitsulo tsiku lililonse. M'mayala—zotengera zazikulu zomwe zimanyamula zitsulo zosungunula kuchokera kung'anjo kupita nazo kumakina otayira—njerwa za magnesium-chromium zimakhala ngati chingwe cholimba. Amaletsa kutentha komwe kungasokoneze chitsulo komanso kutsekereza kutayikira, kuwonetsetsa kuti chitsulo chosungunula chikufika pagawo lake lotsatira m'malo abwino kwambiri opangira kutsika ngati kugudubuza kapena kufota. Ngakhale m'ng'anjo zophulika, mtima wa chitsulo, njerwazi zimateteza madera ovuta kwambiri komanso otsika kuti asawonongedwe ndi gasi wotentha kwambiri (mpaka 2,000 ° C) ndi slags wosungunuka, zomwe zimagwira ntchito kwa nthawi yaitali, yokhazikika yomwe ili yofunikira kuti zitsulo zikhale zokhazikika.
Kwa opanga zitsulo omwe amayesetsa kulimbikitsa zokolola, kuchepetsa ndalama zogwirira ntchito, ndikukhalabe ndi mpikisano, kusankha njerwa zamtundu wa magnesium-chromium si njira yokhayo - ndi kofunika. Njerwa zathu za magnesium-chromium zimapangidwa mokhazikika, pogwiritsa ntchito zida zapamwamba zomwe zimayesedwa mwamphamvu kuti zikwaniritse miyezo yapadziko lonse lapansi. Kudalirika ndi mafakitale otsogola azitsulo ku Asia, Europe, ndi North America, zogulitsa zathu zili ndi mbiri yotsimikizika yopereka magwiridwe antchito, ngakhale m'malo ovuta kwambiri opanga. Gwirizanani nafe lero, ndipo lolani njira yathu yolimbana ndi moto ilimbikitse ntchito yanu yopangira zitsulo, kuchepetsa nthawi yopumira, ndikukuthandizani kuti mukwaniritse kukula kosatha, kwanthawi yayitali.
