Zotayidwa chrome njerwa mtengo

Mtengo wa njerwa za aluminium chrome umasiyanasiyana malinga ndi malo opangira mpaka mitengo yosiyanasiyana. Aluminiyamu njerwa za chrome ndi njerwa za alumina zapamwamba ndi Al2O3 monga gawo lalikulu komanso Cr2O3 yaying’ono. Njerwa zotsekemera zogwiritsa ntchito zotayidwa chromium slag monga zopangira zilinso zotayidwa chromium njerwa, zotchedwanso zotayidwa chromium slag njerwa. Aluminiyamu-chrome njerwa ndizolimba kwambiri poyerekeza ndi njerwa za alumina, ndipo njerwa za aluminium-chrome zimakhalanso ndimakhalidwe abwino otenthetsera makina….

Aluminiyamu chromium njerwa zimapangidwa ndi high alumina bauxite, ndipo ufa wabwino umawonjezeredwa ndi chromite kapena chochokera ku ferroalloy zomera-aluminium chromium slag. Pambuyo poyika kukula kwa tinthu tating’onoting’ono, madzi ndi zamkati zamadzimadzi zimasakanikirana ndi makina amphero, kenako zimapangidwa pamakina osindikizira njerwa, zouma ndikuwotcha kutentha pamwamba pa 1400 ° C. Aluminiyamu chromium slag njerwa zimapangidwa ndi aluminium chromium slag ndikuphwanyidwa mpaka ochepera 3mm. Zomwezo zimagwiritsidwa ntchito pokonzekera ufa wabwino ndikupanga kukula kwa tinthu. Onjezerani mafakitale a phosphoric acid kapena mapepala amkati amadzimadzi amadzimangirira osakaniza. Gwiritsani ntchito njerwa yopangira njerwa, kenako muziwotche pamoto kutentha kwa 1500 ° C mpaka 1600 ° C mutayanika.

Njerwa za Aluminium chrome zitha kugwiritsidwa ntchito ngati njerwa zachitsulo zoumba njerwa, ndipo zimakhala ndi moyo wautali kuposa ma njerwa apamwamba omwe mulibe Cr2O3. Njerwa za Aluminium-chromium slag zimagwiritsidwa ntchito m’malo a tuyere amiyala yazitsulo yamkuwa ndipo imagonjetsedwa ndi dzimbiri kuposa njerwa za magnesia-chromium. Chifukwa cha mphamvu yake yotentha kwambiri, itha kugwiritsidwanso ntchito m’malo otentha kwambiri amoto, monga khoma ndi chowotchera uvuni. Chosavuta cha aluminiyumu chromium slag njerwa ndichabwino kutenthetsa kukana. Pogwiritsidwa ntchito m’malo omwe amasinthasintha kutentha, nthawi zambiri amakhala ndi khungu komanso losweka.
