Usimende we-alumina ephezulu ukhiqizwa ngokuhlanganisa impahla eluhlaza ekhethiwe esithandweni somlilo esikhethekile. Ngemuva kokupholisa, i-clinker iyagaywa kusetshenziswa izigayo zebhola. Izinto ezisetshenziswayo zikasimende we-alumina we-refractory we-CA-70 ophezulu yizinto ze-calcium ehlanzekile ne-alumina ehlanzekile ephezulu. Izinto zokusetshenziswa kufanele zixutshwe ngokwesilinganiso esifanele. Impahla eluhlaza kufanele ishiswe ukuze ihlanganise ingxenye. Okuqukethwe kwe-Al2O3 kuvame ukulawulwa ngaphakathi kwe-68% kuya ku-72%. Izinhlanganisela zayo eziyinhloko yi-CA ne-CA2.
1.Ukusebenza kahle kokushaqeka okushisayo, ukugqwala, ukuguguleka kanye nokumelana nemihuzuko,
2.I-refractoriness ephezulu kanye namandla amahle kakhulu emishini,
3.Kokubili imodi yokusebenza ngezikhathi ezithile nangokuqhubekayo yamukelekile, inciphisa ukuqhekeka kolayini,
4.Umjikelezo wempilo omude futhi ozinzile ukuze ufinyelele ukusebenza kahle okuphezulu,
I-5.Suit yazo zonke izinhlobo zensimbi, ukunciphisa izinsalela kanye ne-porosity yemikhiqizo,
6.Umsebenzi nokonga izindleko ngokufaka nokulungisa izinto ngendlela efanele.

I-alumina Cement isetshenziswa ikakhulukazi ezidingweni ezikhethekile zokwakha izimo eziphuthumayo, ukulungiswa okuphuthumayo, ukumelana ne-sulfate kanye nokwakhiwa kwasebusika. Futhi usimende ophezulu we-alumina refractory usetshenziswa ikakhulukazi ezinhlelweni zephrojekthi eziphuthumayo, njengokuvikela ingcindezi, umgwaqo kanye namaphrojekthi okukhanda akhethekile. Futhi usimende womlilo we-alumina ophezulu osetshenziswa kule ndawo elandelayo:
Ifektri ye-RS refractory ingumphakeli ochwepheshile kasimende we-alumina refractory owasungulwa ekuqaleni kwawo-90s wekhulu lamashumi amabili. Ifektri ye-RS refractory ikhethekile kusimende we-alumina ephezulu iminyaka engaphezu kwengu-20. uma unesidingo esithile sikasimende ophezulu we-alumina refractory, noma unemibuzo ngezinkomba zomzimba nezamakhemikhali ze-zircon mulite refractory bricabout, sicela usithinte mahhala. kanye nefekthri ye-Rs refractory njengomkhiqizi wezitini ze-zircon mulite refractory e-china, inezinzuzo ezithile zokuncintisana ngale ndlela elandelayo:
