Umlotha we-aluminium yinkunkuma eqinileyo eyenziwa ngexesha lenkqubo yokuvelisa i-aluminium, equkethe inani elikhulu le-alumina kunye nezinye izinto ezixabisekileyo. Ukuze kusetyenziswe ngokupheleleyo ezi zixhobo kunye nokunciphisa ungcoliseko lokusingqongileyo, indlela yonyango eqhelekileyo kukunyibilikisa uthuthu lwe-aluminiyam kwi-calcium aluminate. Ukunyibilikisa uthuthu lwe-aluminiyam kwi-calcium aluminate kuneenzuzo ezininzi kunye nexabiso lesicelo. Okokuqala, ukunyibilikisa uthuthu lwe-aluminiyam kunokubuyisela ngokupheleleyo kwaye kusebenzise i-alumina kunye nezinye izinto ezixabisekileyo ezikuyo, ukuphumeza ukusetyenziswa kwakhona kunye nokugcinwa kwemithombo. Okwesibini, ngonyango lweekhemikhali, izinto ezinobuthi kunye neziyingozi kwi-aluminiyam ash zingatshintshwa zibe zizinto ezingenabungozi kunye nezingenabungozi ukukhusela okusingqongileyo kunye nempilo yabantu.
I-calcium aluminate, njengento ebalulekileyo, inoluhlu olubanzi lwezicelo, ngoko ke ukunyibilikisa uthuthu lwe-aluminiyam kwi-calcium aluminate kunokubaluleka kwezoqoqosho kunye nezoshishino. Unyango oluhambelanayo kunye nohlengahlengiso luyafuneka kwi-ash aluminiyam eyahlukeneyo ngexesha lenkqubo yokunyibilikisa. Okwesibini, ngexesha lenkqubo yokunyibilikisa, kuyimfuneko ukulawula iiparamitha ezifana nobushushu kunye neemeko zokusabela ukuze kuqinisekiswe inkqubela phambili egudileyo yokusabela kunye nokuzinza komgangatho wemveliso. Ukunyibilikisa uthuthu lwe-aluminiyam kwi-calcium aluminate yindlela esebenzayo yonyango lwe-aluminiyam yothuthu, enokufikelela ekubuyiseni ubuncwane kunye nokusetyenziswa kwakhona, kunye nokunciphisa ukungcoliseka kwendalo. Sikholelwa ukuba itekhnoloji yokunyibilikisa uthuthu lwe-aluminium kwi-calcium aluminate iya kuba nzima ngakumbi, yenza igalelo elikhulu kuphuhliso oluzinzileyo kunye nokukhuselwa kokusingqongileyo kwamashishini e-aluminium.
Inkqubo entsha yokunyibilikisa kunye nezixhobo eziphuhliswe ngu-Xiye zinokuphatha inkunkuma eqinileyo ye-aluminium ash ukusuka kwisityalo se-aluminium, ikhuphe i-aluminium element emlotheni, kwaye yonke into engcolileyo ibe yi-calcium aluminate, uhlobo lwe-steelmaking deoxidizer, emva kokunyibilika. Ukuguqula inkunkuma ibe bubutyebi, kulwa kakhulu nokungcoliseka kwendalo kwaye iphucula inzuzo yezoqoqosho.
