Izitena zealuminium eziphakamileyo
Izitena zealuminium eziphakamileyo
Izibonelelo zemveliso: ukunyuka kobushushu obuphantsi, ukumelana nokuqina okunamandla, uzinzo olomeleleyo lokukhwankqiswa kobushushu
Ingcaciso yeMveliso
Izitena ze-aluminium eziphakamileyo zine-alumina ezinomxholo ongaphezulu kwe-48% zizinto ezingathathi hlangothi. Yenziwe kwaye yabalwa kwi-bauxite okanye ezinye izinto ezinomxholo ophezulu wealumumina. Izitena ze-aluminium eziphakamileyo zinokuqina okuphezulu kwe-thermal, kunye nokubuyiselwa kwazo ngaphezulu kwe-1770 ℃. Ukuxhathisa kwe-slag kungcono.
Inkqubo yokuveliswa kwezitena eziphezulu zealumni kunye nezitena zodongwe ezininzi ziyafana. Umahluko kukuba inani le-clinker kwizithako liphezulu, elinokuthi libe phezulu njenge-90-95%. I-clinker kufuneka ihlelwe kwaye isuswe ukuze isuse i-iron ngaphambi kokutyunyuzwa, kwaye iqondo lokudubula liphezulu, njenge-Ⅰ, Ⅱ izitena eziphezulu ze-alumina zihlala zi-1500 ～ 1600 ℃ xa zidutyulwa kwitonela yethonela.
