Calcium aluminiyamu, monga chinthu chofunikira, imakhala ndi ntchito zosiyanasiyana, kotero kusungunula phulusa la aluminiyamu mu calcium aluminate kulinso ndi tanthauzo pazachuma komanso mafakitale. Chithandizo chofananira ndikusintha ndikofunikira paphulusa losiyanasiyana la aluminiyamu panthawi yosungunula. Kachiwiri, pa smelting ndondomeko, m`pofunika kulamulira magawo monga kutentha ndi zinthu anachita kuonetsetsa bwino patsogolo anachita ndi bata la mankhwala khalidwe. Kusungunula phulusa la aluminiyamu mu calcium aluminate ndi njira yabwino yothetsera phulusa la aluminiyamu, yomwe ingathe kukwaniritsa kuchira ndikugwiritsanso ntchito, ndikuchepetsa kuwononga chilengedwe. Tikukhulupirira kuti ukadaulo wosungunula phulusa la aluminiyamu mu aluminiyamu ya calcium ukhala wotsogola kwambiri, zomwe zimathandizira kwambiri chitukuko chokhazikika komanso kuteteza chilengedwe cha mabizinesi a aluminiyamu.
Njira yatsopano yosungunulira ndi zida zopangidwa ndi Xiye zimatha kuthana ndi zinyalala zolimba za phulusa la aluminiyamu kuchokera ku chomera cha aluminiyamu, kuchotsa chinthu cha aluminiyamu muphulusa, ndipo zonyansa zonsezo zimakhala aluminiyamu ya calcium, mtundu wa deoxidizer wopangira zitsulo, pambuyo posungunula. Kusandutsa zinyalala kukhala chuma, kumalimbana kwambiri ndi kuipitsidwa kwa chilengedwe komanso kumapindulitsa pazachuma.
