Amatafari maremare ya alumina akorwa hamwe na chamotte ya bauxite nkibikoresho fatizo byingenzi, ikarasa kuri 1450-1470 ° C hakoreshejwe uburyo bunoze kandi bugenzura neza. Amatafari maremare ya Alumina yakozwe hamwe na alumina cyangwa ibindi bikoresho fatizo birimo alumina nyinshi binyuze mu kubumba no kurasa. kuberako itagira aho ibogamiye imitungo ya alumina irashobora kurwanya aside irwanya isuri.
Amatafari maremare ya Alumina
Genda Hitamo kandi ushungure chamotte ya deironing mbere yo kumeneka, bishobora kuzamura ubwiza bwamatafari ya alumina. Kuberako hari igipimo kinini cya grog mubikoresho bishobora kugera kuri 90 ~ 95%. Hitamo kandi werekane deironing mbere yuko grog ihonyora.
Ibyiciro bitatu bya Alumina Amatafari
Ukurikije ibintu bitandukanye bya Al2O3, amatafari maremare ya alumina arashobora gushyirwa mubyiciro bitatu mubushinwa.
Icyiciro cya I Amatafari ya Alumina Yisumbuye afite ibice birenga 75% bya Al2O3.
Icyiciro cya II Amatafari ya Alumina yo hejuru afite 60 ~ 75% ya Al2O3.
Icyiciro cya III Amatafari yo hejuru ya Alumina afite 48 ~ 60% ya Al2O3.
Ibiranga amatafari maremare ya Alumina
Amatafari maremare ya alumina afite ibintu byiza nkubushyuhe bwo hejuru, kwangirika gukomeye no kwambara, ubwinshi bwinshi, ibyuma bike, nibindi.
