Mu mafakitale otentha kwambiri, magwiridwe antchito a zipangizo amatsimikizira mwachindunji kukhazikika ndi kugwira ntchito bwino kwa kupanga.Njerwa zopyapyala kwambiri za alumina, popeza zipangizo zapamwamba kwambiri zotsukira zomwe zimapangidwa makamaka ndi alumina bauxite yapamwamba, zakhala chisankho chabwino kwambiri cha mafakitale ambiri otentha kwambiri chifukwa cha magwiridwe antchito awo abwino kwambiri, kuteteza chitukuko cha zitsulo zapadziko lonse lapansi, zipangizo zomangira, mankhwala ndi mafakitale ena.
Ubwino waukulu wa njerwa zopyapyala zokhala ndi alumina wambiri umachokera ku kapangidwe kake kapadera komanso njira zopangira. Njerwa izi zimapangidwa ndi clinker yokhala ndi alumina yambiri ya bauxite yokhala ndi alumina yosachepera 48% ngati chophatikiza, kuphatikiza ndi zomangira mosiyanasiyana, kenako n’kupanga, kuumitsa, ndi kuyatsa pa kutentha kwakukulu. Njerwa zopyapyala zokhala ndi alumina wambiri zimakhala ndi kukana bwino kwambiri, zomwe zimatha kupirira kutentha kwakukulu kuyambira 1770°C mpaka 1790°C. Ngakhale m’malo otentha kwambiri, zimatha kusunga umphumphu wa kapangidwe kake, kukana kuwonongeka kwa kutentha kwakukulu pazida. Kutentha kwawo kofewa bwino kumatsimikizira kuti sizingasinthe ndi kugwa pansi pa kupanikizika kwina ndi kutentha kwakukulu, kupereka chitsimikizo chodalirika cha magwiridwe antchito okhazikika a zida zopyapyala. Kuphatikiza apo, njerwa zopyapyala zokhala ndi alumina zambiri zimakhala ndi kukana kwakukulu kwa kutentha, zomwe zimawalola kukhalabe ndi magwiridwe antchito okhazikika panthawi ya kusintha kwa kutentha pafupipafupi, kuchepetsa kusweka ndi kuphulika komwe kumachitika chifukwa cha kupsinjika kwa kutentha ndikuwonjezera moyo wawo wautumiki. Zimakhalanso ndi kukana kwakukulu ku mankhwala osiyanasiyana. Kaya ndi slag mu njira ya zitsulo kapena mpweya wowononga popanga mankhwala, n'zovuta kuwawononga kwambiri.
Njerwa zokhala ndi alumina yochuluka zimagwiritsidwa ntchito m'njira zosiyanasiyana. Mu makampani opanga zitsulo, ndi zinthu zofunika kwambiri pakupanga ng'anjo zopangira zitsulo, ng'anjo zopangira zitsulo, ndi ng'anjo zotenthetseranso. Zingathe kukana kuwonongeka kwa chitsulo chosungunuka ndi slag yotentha kwambiri, kuonetsetsa kuti njira yosungunulira ikuyenda bwino komanso kukonza moyo wa zida ndi ntchito yabwino yopangira. Mu makampani opanga zida zomangira, njerwa zokhala ndi alumina yochuluka zimagwiritsidwa ntchito kwambiri pazida monga ma uvuni ozungulira simenti ndi ng'anjo zosungunulira magalasi. M'malo okhala ndi kutentha kwambiri, kupukuta mpweya mwachangu, komanso kusweka kwa zinthu, zimathabe kugwira ntchito bwino, kuthandizira ntchito yokhazikika yopanga zida zomangira. Mu makampani opanga mankhwala, njerwa zokhala ndi alumina yochuluka zimagwira ntchito yofunika kwambiri mu ng'anjo zokhala ndi kutentha kwambiri komanso zotenthetsera mpweya. Ndi kukana kwawo kwabwino kwa mankhwala, zimaonetsetsa kuti njira yopangira mankhwala ndi yotetezeka komanso yogwira mtima.
Tili ndi zida zapamwamba zopangira komanso njira yowongolera bwino kwambiri. Chingwe chilichonse, kuyambira kugula zinthu zopangira mpaka kutumiza zinthu zomalizidwa, chimayang'aniridwa mosamala. Mwa kugwiritsa ntchito njira zotsogola zopangira padziko lonse lapansi, timaonetsetsa kuti mtundu wa njerwa zokhala ndi alumina wambiri ukugwirizana ndi miyezo yapadziko lonse lapansi. Nthawi yomweyo, timaperekanso chithandizo chaukadaulo chaukadaulo komanso ntchito zonse zogulitsa pambuyo pogulitsa. Malinga ndi zosowa zosiyanasiyana za makasitomala, timapereka mayankho opangidwa ndi anthu kuti tiwonetsetse kuti njerwa zokhala ndi alumina wambiri zitha kugwira ntchito bwino kwambiri pakugwiritsa ntchito.
Kusankha njerwa zathu zopyapyala za alumina kumatanthauza kusankha mtundu ndi kudalirika. Kaya mukufuna kugula kwakukulu kapena njira zaukadaulo zopyapyala, tikhoza kukwaniritsa zosowa zanu. Timalandira makasitomala ochokera padziko lonse lapansi kuti alumikizane nafe ndikugwira ntchito limodzi kuti apange tsogolo labwino la makampani otentha kwambiri!
