Cov cib rwb thaiv tsev uas muaj txhuas siab yog cov khoom siv hluav taws xob uas ua los ntawm bauxite ua cov khoom siv tseem ceeb nrog cov ntsiab lus Al2O3 tsawg kawg 48%. Nws cov txheej txheem tsim khoom yog txoj kev ua npuas ncauj, thiab kuj tseem tuaj yeem ua rau hlawv tawm txoj kev ntxiv. Cov cib rwb thaiv tsev uas muaj txhuas siab siv tau rau cov txheej rwb thaiv tsev thiab cov khoom seem uas tsis muaj kev yaig thiab kev yaig ntawm cov khoom siv kub siab. Thaum sib cuag ncaj qha nrog nplaim taws, feem ntau qhov kub ntawm cov cib rwb thaiv tsev uas muaj txhuas siab yuav tsum tsis pub siab tshaj 1350 ° C.
Cov yam ntxwv ntawm cov cib ua los ntawm cov khoom siv hluav taws xob siab
Nws muaj cov yam ntxwv ntawm kev tiv taus kub siab, lub zog siab, qhov ceev tsawg, porosity siab, thermal conductivity qis, tiv taus kub siab, thiab kev ua haujlwm zoo rwb thaiv tsev kub. Nws tuaj yeem txo qhov loj thiab qhov hnyav ntawm cov khoom siv thermal, luv lub sijhawm cua sov, xyuas kom meej tias lub cub tawg kub sib npaug, thiab txo qhov poob cua sov. Nws tuaj yeem txuag hluav taws xob, txuag cov khoom siv hauv tsev cub tawg thiab ua kom lub neej ua haujlwm ntawm lub cub tawg ntev dua.
Vim nws cov porosity siab, qhov ceev tsawg thiab kev ua haujlwm zoo thermal rwb thaiv tsev,Cov cib ua los ntawm txhuas siab thiab sib duaSiv dav ua cov khoom siv rwb thaiv tsev thermal hauv qhov chaw nruab nrab ntawm cov cib refractory thiab lub cub tawg hauv ntau lub cub tawg kev lag luam kom txo qhov kub ntawm lub cub tawg thiab tau txais kev siv hluav taws xob zoo. Lub ntsiab lus yaj ntawm anorthite yog 1550 ° C. Nws muaj cov yam ntxwv ntawm qhov ceev qis, cov coefficient nthuav dav thermal me me, cov thermal conductivity qis, thiab muaj nyob ruaj khov hauv kev txo cov huab cua. Nws tuaj yeem hloov ib feem ntawm av nplaum, silicon, thiab cov khoom siv refractory aluminium siab, thiab paub txog kev txuag hluav taws xob thiab txo qis kev tso pa tawm.
