Aluminiyamu yopanda ndodo imatha kuponyedwa
Zambiri za aluminiyamu yopanda ndodo zotayidwa
Mndandanda wa zipangizozi ndi mtundu watsopano wa zinthu zomwe zimakhala ndi simenti yochepa komanso ufa wa ultrafine ufa wopangidwa ndi high-purity mullite, andalusite ndi sillimanite.Chifukwa cha kuphatikiza kwa zinthu zoyera kwambiri komanso ufa wapamwamba kwambiri, mndandanda wazinthuzi uli ndi kachulukidwe kambiri, mphamvu zambiri, komanso kukhazikika kwamphamvu kwamafuta.Mchere, etc.), akhoza kuchepetsa wettability wa zotayidwa ndi kasakaniza wazitsulo ndi slag kuti zipangizo refractory, ndi kusintha kukana dzimbiri, kukana kukokoloka, ndi sanali kumamatira a aluminiyamu refractory zipangizo kuti zotayidwa madzi okhala ndi zigawo zikuluzikulu monga mchere ndi flux.Ntchito ya slag ndi slag imalepheretsa aluminium ndi ma alloys ndi slag kuti asalowe muzinthu zokanira, kukulitsa moyo wa ng'anjo yamoto.Zoyenera kusungunula ng'anjo, ng'anjo zosasunthika, zochapira, zomangira za aluminiyamu.
