High aluminium lub teeb yuag rwb thaiv tsev cib yog cov khoom siv hluav taws kub-insulating refractory ua los ntawm bauxite ua cov khoom siv tseem ceeb nrog Al2O3 cov ntsiab lus tsis tsawg dua 48%. Nws cov txheej txheem ntau lawm yog txoj kev ua npuas ncauj, thiab tseem tuaj yeem hlawv tawm ntxiv. High aluminium lub teeb yuag rwb thaiv tsev cib yuav siv tau rau masonry rwb thaiv tsev txheej thiab qhov chaw uas tsis muaj zog erosion thiab yaig ntawm high-temperature molten cov ntaub ntawv. Thaum ncaj qha nyob rau hauv kev sib cuag nrog cov nplaim taws, feem ntau qhov kub thiab txias ntawm aluminium lub teeb yuag rwb thaiv tsev cib yuav tsum tsis txhob siab tshaj 1350 ° C.
Cov yam ntxwv ntawm siab aluminium lub teeb yuag rwb thaiv tsev cib
Nws muaj cov yam ntxwv ntawm qhov kub thiab txias tsis kam, siab zog, tsis tshua muaj qhov ntom ntom, siab porosity, tsis tshua muaj thermal conductivity, kub tsis kam, thiab zoo thermal rwb thaiv tsev kev ua tau zoo. Nws tuaj yeem txo qhov loj thiab qhov hnyav ntawm cov khoom siv thermal, txo lub sij hawm cua sov, ua kom lub qhov cub zoo sib xws, thiab txo cov cua sov. Nws tuaj yeem txuag hluav taws xob, txuag cov khoom siv hluav taws xob hauv tsev thiab ua kom lub cub tawg ua haujlwm ntev.
Vim nws cov porosity siab, tsis tshua muaj qhov ntom ntom thiab zoo thermal rwb thaiv tsev kev ua haujlwm,high aluminium lightweight rwb thaiv tsev bricksyog dav siv raws li thermal rwb thaiv tsev sau cov ntaub ntawv nyob rau hauv qhov chaw ntawm refractory cib thiab lub cub tawg nyob rau hauv ntau yam industrial kilns kom txo tau tshav kub dissipation ntawm lub cub tawg thiab tau txais high zog efficiency. Lub melting point ntawm anorthite yog 1550 ° C. Nws muaj cov yam ntxwv ntawm qhov ntom ntom, me me thermal expansion coefficient, tsis tshua muaj thermal conductivity, thiab ruaj khov nyob hauv kev txo cov cua. Nws tuaj yeem hloov cov av nplaum, silicon, thiab cov ntaub ntawv siab aluminium refractory, thiab paub txog lub zog txuag thiab emission txo.
