Isitini somlilo se-Alumina silica uhlobo lwezinto zokuphikisa ze-alumina silica, isitini sokuphikisa se-alumina silicate sinezici zokuphikisa okuphezulu, ukumelana nokuguguleka okuhle kanye namandla aphezulu. Isitini sokuphikisa se-aluminium silicate sihlanganisa izinhlobo eziningi zezitini zomlilo ezifana nesitini se-silica, isitini sobumba, isitini se-alumina esiphezulu, isitini se-mullite kanye nesitini se-corundum. Isitini somlilo se-alumina silica singasetshenziswa kuzo zonke izinhlobo zemishini yokushisa.
Ukuhlukaniswa Kwezitini Zomlilo ze-Alumina Silica
Ngokuya ngokulandelana kokuqukethwe okwandayo kusuka ku-SiO2 kuya ku-Al2O3, izitini zomlilo ze-aluminium silicon zihlukaniswa ngezigaba ezilandelayo
Isitini se-silica: okuqukethwe kwe-SiO2 kungaphezu kwama-93%,
Isitini sobumba: okuqukethwe yi-Al2O3 kungu-30%-48%,
Isitini se-alumina esiphezulu: okuqukethwe kwe-Al2O3 kungaphezu kuka-48%,
Izitini eziningi: okuqukethwe kwe-Al2O3 kukhulu noma kulingana no-72%, kanti okuqukethwe kwe-SiO2 kukhulu noma kulingana no-28%,
Isitini se-Corundum: okuqukethwe kwe-Al2O3 kungaphezu kuka-90%.
Ukusetshenziswa Kwezitini Zomlilo ze-Alumina Silica
Izitini ze-silica zisetshenziswa kakhulu ukwakha i-oven ye-coke, i-oven yengilazi, i-oven ye-ceramic, i-carbon calcinations furnace futhi azifanele ukusetshenziswa emishinini yokushisa enokushintshashintsha kwezinga lokushisa okungaphansi kuka-600 ℃.
Izitini zobumba zihlala zisetshenziswa ku-blast furnace, i-hot blast heater, i-heating furnace, i-power boiler, i-lime kiln, i-rotary kiln, i-ceramic kiln kanye ne-calcining furnace.
Izitini ze-alumina eziphakeme zisetshenziswa kakhulu ekukhiqizweni kwensimbi, embonini yezinsimbi ezingezona insimbi kanye neminye imboni.
Izitini ze-Mullite zisetshenziswa kuzo zonke izinhlobo ze-furnace ezifakwe ubuso obushisayo kanye ne-backing lining embonini ye-metallurgical, embonini ye-petrochemical, embonini yezinto zokwakha, embonini ye-ceramic, kanye nasembonini yemishini.
Isitini se-Corundum singasetshenziswa ku-blast furnace, isitofu esishisayo, i-glass furnace nokunye.

Umkhiqizi Wezitini Zomlilo ze-Alumina Silica
Umkhiqizi wezitini ezimelana ne-RS njengomunye wabakhiqizi bezitini ezimelana ne-oven abahamba phambili, ugxile ekusikeni nasekubumbeni izitini ezimelana ne-oven ngokwezidingo zamakhasimende, ezingakukhiqizela izitini zomlilo ze-alumina silica ezisezingeni eliphezulu.
