O piliki maualuga-alumina mo ogaumu o loʻo faia i luga o le bauxite maualuga e avea ma mea autu autu, lea e faʻapipiʻiina, faʻapipiʻi, faʻagogo ma susunuina i le vevela maualuga. O mea ia e le mafai ona fa'aaogaina mo le fa'apipi'iina o ogaumu.
1. Fa'ailoga fa'aletino ma kemisi o piliki alumina maualuga
FA'asinomaga | SK-35 | SK-36 | SK-37 | SK-38 | SK-39 | SK-40 |
Refractoriness(℃) ≥ | 1770 | 1790 | 1820 | 1850 | 1880 | 1920 |
Fa'atele (g/cm3) ≥ | 2.25 | 2.30 | 2.35 | 2.40 | 2.45 | 2.55 |
Fa'aaliga manino(%) ≤ | 23 | 23 | 22 | 22 | 21 | 20 |
Malosi Tu'imomomo Malili(MPa) ≥ | 40 | 45 | 50 | 55 | 60 | 70 |
Suiga Tumau Linear@1400°×2h(%) | ±0.3 | ±0.3 | ±0.3 | ±0.3 | ±0.2 | ±0.2 |
Refractoriness I lalo o uta @ 0.2MPa(℃) ≥ | 1420 | 1450 | 1480 | 1520 | 1550 | 1600 |
Al2O3(%) ≥ | 48 | 55 | 62 | 70 | 75 | 80 |
Fe2O3(%) ≤ | 2.0 | 2.0 | 2.0 | 2.0 | 2.0 | 1.8 |
2. O fea o loʻo faʻaogaina ai piliki alumina maualuga i totonu o ogaumu?
O piliki maualuga-alumini e fausia i luga o le ogaumu ogaumu o le ogaumu sasa. O le ogaumu ogaumu e tu i le pito i luga o le ogaumu sausau. O lona lautele e faasolosolo malie ona faʻalauteleina mai luga i lalo e faʻafetaui i le faʻalauteleina o le vevela o le tau ma faʻaitiitia ai le feteʻenaʻi o le puipui o le ogaumu i luga o le moliaga. O le tino o le ogaumu o lo'o nofoia le ogaumu sausau. 50% -60% o le maualuga aoga. I totonu o lenei siosiomaga, e manaʻomia e le ogaumu le faʻamalieina o ia manaʻoga, ma o uiga o piliki alumina maualuga o le maualuga o le refractoriness, maualuga le faʻamaluluina o le vevela i lalo o le avega, faʻamaʻi faʻamaʻi, tetee alkali, malosi malosi i le pala, ma le lelei o le ofuina. E mafai ona faʻamalieina, o lea e fetaui lelei mo le tino o le ogaumu e faʻapipiʻiina i piliki alumina maualuga.
O loʻo i luga o se folasaga i piliki alumina maualuga mo ogaumu faʻafefe. O le siosiomaga faʻapipiʻi o le ogaumu faʻalavelave e lavelave ma e tele ituaiga o mea e faʻaaogaina. O piliki alumina maualuga o se tasi oi latou. E i ai 3-5 faʻamatalaga o piliki alumina maualuga faʻaaogaina. O piliki alumina maualuga a Robert e mafai ona faʻaaogaina i le tele o umu. Afai e mana'omia, fa'amolemole fa'afeso'ota'i mai matou.
