Izitini ze-alumina eziphakeme zikhiqizwa nge-chamotte ye-bauxite ekhethiwe njengezinto eziyinhloko zokusetshenziswa, ezishiswa ku-1450-1470°C ngenqubo ethuthukisiwe enokulawulwa kwekhwalithi okuqinile. Izitini ze-Alumina Eziphezulu zoMlilo zenziwa nge-alumina noma ezinye izinto zokusetshenziswa eziqukethe okuqukethwe okuphezulu kwe-alumina ngokubumba nangokushisa. Ngenxa yesakhiwo sayo sokungaguquguquki, i-alumina engathathi hlangothi ingamelana nokumelana nokuguguleka kwe-asidi.
Inqubo Yezitini Eziphezulu Ze-Alumina
Vula i-Select bese uhlinza i-chamotte ukuze ikhishwe i-ayina ngaphambi kokuphuka, okungathuthukisa ikhwalithi ephezulu yezitini ze-alumina. Ngoba kunesilinganiso esiphezulu se-grog ezithakweni esingafinyelela ku-90-95%. Khetha bese uhlola i-deayina ngaphambi kokuba i-grog ichotshozwe.
Amabanga Amathathu E-High Alumina Brick
Ngokusho kokuqukethwe okuhlukile kwe-Al2O3, izitini ze-alumina eziphakeme zingahlukaniswa ngamaBanga amathathu eShayina.
Izitini ze-Alumina Eziphezulu Zebanga I zinokuqukethwe kwe-Al2O3 okungaphezu kuka-75%.
Izitini ze-Alumina Eziphezulu Zebanga II zinokuqukethwe kwe-Al2O3 okungu-60 ~ 75%.
Izitini ze-Alumina Eziphezulu Zebanga Lesithathu zinokuqukethwe okungu-48 ~ 60% kwe-Al2O3.
Izici Zezitini Eziphezulu Ze-Alumina
Isitini se-alumina esiphezulu sinezici ezinhle njengokusebenza kahle kwezinga lokushisa eliphezulu, ukugqwala okuhle kanye nokumelana nokuguguleka, ubuningi obukhulu, okuqukethwe kwensimbi okuphansi, njll.

Isicelo Sezitini Eziphezulu Ze-Alumina
Izitini ze-alumina eziphakeme zingasetshenziswa esithandweni somlilo, esitovini esishisayo, esithandweni sikagesi. kanye nezitini zomlilo ze-alumina eziphakeme ezisetshenziswa emikhakheni yensimbi nensimbi, engashisi, ingilazi, usimende, i-ceramics, i-petrochemical, umshini, i-boiler, imboni yokukhanya, amandla, kanye nemboni yezempi njll.
