Brik Alumina jeneralman refere a brik silikat Alumina, ak kontni Al2O3 ak SiO2 kòm sa ki prensipal, ak Fe2O3, Na2O, K2O, TiO2 kòm enpurte.
Avèk diferan kontni Al2O3, brik alumina gen ladan brik ajil refractory (kontni Al2O3 nan 48% ak Kaolin kòm matyè premyè), brik alumina segondè (kontni Al2O3 48% -85%, ak boksit kòm matyè premyè), brik mullite dans, brik silimanite, brik korundum ak kontni korundum (Al90O3% 3).
Done teknik nan brik alumina jeneralman gen ladan konpozisyon chimik (kontni Al2O3 ak Fe2O3), dansite esansyèl, porosite aparan, fòs kraze frèt, chanjman revètman pèmanan ak refractoriness anba chaj 0.2 MPa.
Avèk pi wo kontni Al2O3, brik yo ak
Mwens enpurte
pi bon rezistans tèmik
Pi wo fòs kraze
Pi bon rezistans korozyon
Mwens chanjman pèmanan revètman
Pèfòmans ki pi estab
Men, rezistans chòk tèmik nan brik corumdum yo pi fèb pase brik alumina segondè ak brik mullite, se konsa brik ki gen pi wo kontni Al2O3 yo jeneralman itilize kòm pawa k ap travay nan gwo founo dife, au ak chodyè ak tanperati ki estab.
Pwosesis pwodwi: Manje matyè premyè--Batching--Fòm ak laprès idwolik-- tire nan fou tinèl--- enspeksyon ak anbalaj nan depo
