Ƙananan creep high alumina tubalin don murhun wuta mai zafi

Low creep da manyan tubalin alumina sune manyan kayan ƙyalli masu ƙyalli waɗanda aka yi da alumina, fused corundum, da fused mullite a matsayin manyan albarkatun ƙasa.

Features

1. Refractoriness

Ƙaƙƙarfan ƙanƙara mai ƙanƙanta da babban tubalin alumina ya fi na yumɓu na yumɓu da tubalin siliki, ya kai 1750 ~ 1790 ℃, wanda shine babban abin ƙyama.

2. Load softening zazzabi

Saboda samfuran manyan alumina suna da babban Al2O3, ƙarancin ƙazanta, da ƙarancin gilashin gilashi, zazzabi mai laushi yana da girma fiye da na tubalin yumbu. Koyaya, saboda lu’ulu’u na mullite ba su samar da tsarin cibiyar sadarwa ba, har yanzu zafin zafin da ke ɗaukar nauyi bai kai na tubalin silica ba.

3. Tsayayyar slag

Ƙananan creep da manyan tubalin alumina sun ƙunshi ƙarin Al2O3, wanda ke kusa da kayan ƙin tsaka tsaki, kuma yana iya tsayayya da lalacewar ɓarna na acidic slag da alkaline slag. Saboda yana ƙunshe da SiO2, ikon yin tsayayya da slag na alkaline yana da rauni fiye da na slag acidic.

amfani

An fi amfani da shi don rufin murhun wuta, murhun wuta mai zafi, saman murhun wutar lantarki, murhun murɗawa, murhu mai jujjuyawa, da murhun wuta.
