Izitena zealumini ephezulu Indawo yokunyibilika

Izitena eziphezulu ze-alumina luhlobo lwezitena eziphikisayo. Ngokomxholo we-alumina, izitena eziphezulu ze-alumina zahlulwe kwizitena ezikhethekileyo ze-alumina ephezulu, i-primary, i-sekondari kunye ne-tertiary high high alumina. Umxholo we-alumina wezitena ezintathu eziphezulu ze-alumina zihluke. Ukuphakama komxholo we-aluminiyam, kuncinci okunye ukungcola, ngaphantsi kweglasi yomzimba ekulula ukunyibilika, kunye nobushushu obuhlukeneyo bokuthambisa phantsi komthwalo.

1. Izitena ezikhethekileyo ze-alumina eziphezulu: umxholo we-alumina mkhulu kune-80%, kunye nobushushu bokunciphisa umthwalo malunga ne-1550 ° C.

2. Ibanga lokuqala isitena se-alumina ephezulu: Umxholo we-alumina mkhulu kune-75%, kunye nobushushu bokuthambisa umthwalo malunga ne-1510 ℃.

3. Isitena sesibini se-alumina ephezulu: Umxholo we-alumina mkhulu kune-65%, kunye nobushushu bokuthambisa umthwalo malunga ne-1460 ℃.

4. Izitena ezintathu ze-alumina eziphezulu: umxholo we-aluminium ungaphezulu kwe-55%, kwaye ukushisa okuthambileyo phantsi komthwalo malunga ne-1420 ℃.
