Pụrụ iche nke elu alumina brik na -agbanwe agbanwe

N’etiti aluminosilicate refractory ihe, elu alumina refractory brik nwere elu refractoriness. Dị ka ọdịnaya nke Al2O3 na ngwaahịa na-abawanye, na refractoriness na-abawanye, n’ozuzu bụghị ala karịa 1750 ℃ ​​~ 1790 ℃. Mgbe alumina ọdịnaya bụ ukwuu karịa 95%, refractoriness nwere ike ịdị elu dị ka 1900 ℃ ~ 2000 ℃.

Na mgbakwunye na nke SiO2 na metal oxides, ibu dị nro okpomọkụ nke elu alumina refractory brik na-ebelata. The ibu nro okpomọkụ nke nkịtị elu alumina brik bụ 1420 ℃～ 1530 ℃. Ọnọdụ okpomọkụ dị nro nke ngwaahịa corundum nwere ọdịnaya Al2O3 karịa 95% dị n’elu 1600 ℃.

Brick ndị na-atụgharị alumina dị elu nwere ọrụ nke iguzogide slags dị iche iche. N’ihi nnukwu ọdịnaya nke Al2O3 na ngwaahịa na nnọpụiche ya, ọ nwere nguzogide corrosion siri ike na acid na alkali slag.

Brick alumina dị elu nwere nguzogide ujo. Corundum na kristal mullite na-ebikọ ọnụ, na ọnụọgụ mgbasawanye nke corundum dị ukwuu karịa nke mullite. Ya mere, mgbe okpomọkụ na-ebili, ọdịiche mgbasawanye nke ngwaahịa ga-eme ka nrụgide nrụgide. Ya mere, nguzogide okpomọkụ nke brik alumina dị elu adịghị mma, ọnụ ọgụgụ nke mmiri jụrụ oyi bụ naanị 3 ruo 5 ugboro.
