Izitini Ezine-Alumina Ephakeme Ezivuselelayo
Izitini eziqinile ze-alumina ephezuluziwuhlobo lwezinto eziphikisayo ze-aluminosilicate ezine-alumina njengengxenye eyinhloko. Njengoba okuqukethwe kwe-alumina kungaphezu kuka-48%, zihlukaniswa njengezinto eziphikisayo ezingathathi hlangothi, ezenziwe nge-bauxite noma ezinye izinto zokusetshenziswa ezinokuqukethwe okuphezulu kwe-alumina ngokubumba kanye nokugaya.
Ukuhlukaniswa:
Ngokusekelwe kokuqukethwe kwe-alumina, zihlukaniswe ngamaqembu amathathu:
Ibanga 1: izitini ze-alumina ephezulu (okuqukethwe kwe-Al₂O₃ > 75%)
Ibanga lesi-2: izitini ze-alumina ephezulu (okuqukethwe kwe-Al₂O₃: 60%~75%)
Ibanga lesi-3: izitini ze-alumina ephezulu (okuqukethwe kwe-Al₂O₃: 48%~60%)
Inqubo Yokukhiqiza:
Inqubo yokukhiqiza izitini ze-alumina ephezulu ifana neyezitini zobumba ezisebenzisa ama-clinker amaningi. Ingxenye ye-clinker engxubeni ingaba phezulu njengo-90% ~ 95%. Ngaphambi kokuchoboza, i-clinker idinga ukuhlungwa, ihlungwe futhi ihlungwe ukuze isuswe insimbi. Izinga lokushisa lokudubula liphezulu kakhulu; Izitini ze-alumina eziphezulu zeBanga 1 neBanga 2 ngokuvamile zishiswa ku-1500℃ ~ 1600℃ ezitsheni zomlilo.
Izakhiwo ze-Physicochemical:
1. Ukungavuvukali
Ingakwazi ukumelana namazinga okushisa aphezulu ngaphezu kuka-1770℃, ngokuvamile kusukela ku-1750℃ kuya ku-1790℃. Ukungazweli kahle kuyanda ngokukhuphuka kokuqukethwe kwe-alumina.
2. Izinga Lokushisa Lokuthambisa Umthwalo
Ngokuvamile kungu-1420℃ ~ 1530℃. Ngenxa yokuqukethwe okuphezulu kwe-alumina, okuqukethwe okuphansi kokungcola kanye nokwakheka okuncane kwesigaba sengilazi esiguquguqukayo, izinga lokushisa layo lokuthambisa umthwalo liphakeme kunelezitini zobumba zomlilo.
3. Amandla Okucindezela Okubandayo
Amandla okucindezela abandayo ezitini ze-alumina eziphezulu zeBanga 1 (LZ-80) angama-≥ 70 MPa, kanti lawo ezitini ze-alumina eziphezulu zeBanga 3 (LZ-48) angama-≥ 40 MPa.
4. Ukumelana ne-Slag
Izitini ezine-alumina ephezulu ziseduze nezinto ezingathathi hlangothi ezimelana nokuguguleka, ezingamelana nokuguguleka kwama-slag ane-acidic kanye ne-alkaline, kodwa ukumelana kwazo nama-slag ane-alkaline kubuthakathaka kunokumelana nama-slag ane-acidic.
5. Ukuvuleka Okubonakalayo
Ubuningi obubonakalayo bezitini ze-alumina ephezulu zebanga loku-1 bungu-≤ 21%, kanti obezitini ze-alumina ephezulu zebanga lesi-3 bungu-≤ 22%.

Izitini ze-alumina eziphakemezisetshenziswa kakhulu kwi-VOD, i-AOD, ama-blast furnaces, ama-hot blast furnaces, i-EAF, ama-reverberatory furnaces, kanye nama-rotary kiln linings. Ngaphezu kwalokho, izitini ze-alumina eziphakeme nazo zisetshenziswa kabanzi njengezitini zokuhlola isitoreji sokushisa esivulekile, ama-plugs ezinhlelo zokuthela, izitini ze-nozzle, njll.
