Yakakwirira alumina zvidhinha yakanyungudika

High alumina zvidhinha imhando yezvidhinha zvinoramba. Zvinoenderana nealumina yemukati, yakakwira alumina zvidhinha yakakamurwa kuva yakakosha yakakwirira alumina zvidhinha, yepuraimari, yechipiri uye yepamusoro yepamusoro alumina zvidhinha. Iyo alumina yemukati yeatatu yakakwirira alumina zvidhinha zvakasiyana. Iyo yakakwira iyo aruminiyamu zvirimo, kushomeka kumwe kusvibiswa, kushoma kwemuviri wegirazi uri nyore kunyunguduka, uye tembiricha yekupfavisa yakasiyana pasi pemutoro.

1. Special high-alumina zvidhinha: iyo alumina yemukati yakakura kupfuura 80%, uye tembiricha yekupfavisa mutoro ingangoita 1550 ° C.

2. Chekutanga giredhi yakakwira alumina zvidhinha: Iyo alumina yemukati yakakura kupfuura 75%, uye tembiricha yekupfavisa mutoro ingangoita 1510 ℃.

3. Sekondari yakakwira alumina zvidhinha: Iyo alumina yemukati yakakura kupfuura 65%, uye tembiricha yekupfavisa mutoro ingangoita 1460 ℃.

4. Zvidhinha zvitatu zvepamusoro-aluminium: zvinyorwa zvealuminium zvinopfuura 55%, uye kunyorova kwekushisa pasi pemutoro kunosvika 1420 ℃.
