Andalusite Castableyog ib qho kev ua tau zoo Refractory Castable ua los ntawm ntuj thiab thiab cov khoom tseem ceeb. Andalusite yog cov khoom siv txhuas sixeric (al₂sioct
Andalusite castables yog tus cwj pwm los ntawm zoo slag tiv taus thiab thermal poob siab kuj. Tshwj xeeb tshaj yog thaum kub siab, tus nqi hloov pauv yog me dua. Castables nrog thiab Andalusite ntxiv muaj qhov ntim qis dua vim yog cov yam ntxwv ntawm cov khoom siv raw lawv tus kheej.
Kev sib xyaw ua ke ntawm cov me nyuam loj ntawm Andalusite sib sau ua ke hauv cov khoom siv raw ntawm Andalusite Castable tseem tuaj yeem hloov kho cov ntsuas hluav taws xob. Tom qab kev kho cua sov, lub ntim nthuav dav tsis muaj zog thiab cov kab hloov pauv tau txo qis. Lub thermal poob siab tsis kam ntawm qhov Castable no yog vim qhov kev txiav txim siab ntawm cov Andalusite ntawm cov qauv kub los ua tus qauv ntawm mullite thiab silicon-nplua nuj iav theem. Cov Silicon-nplua nuj iav theem tsim los ntawm Andalusite tuaj yeem sau cov pores thiab txhawb kev txhim kho ntawm Sintering degree. Ib qho ntxiv, cov Castable nrog Andalususite muaj cov qauv siv hluav taws xob maj mam maj mam qeeb thaum lub thermal poob siab, thiab lub thermal poob siab yuav tseem yuav txhim kho.
Cov Oxide txheej ntawm Andalusite aggregate yog qhov tsis yooj yim, thiab kev qhia ntawm Andalusite agregate tau txhim kho cov oxidation tsis kam ntawm cov Castable. Cov iav iav ua tom qab kev txiav txim siab ntawm Andalusite puv cov pores thiab tiv thaiv cov pa oxygen los ntawm kev nkag mus rau lub Castable. Raws li cov particle loj ntawm Andalusite ua ke tsawg dua thiab cov kev pab kub siab ntxiv, qhov ntau ntawm cov thawv silicon, qhov ntau ntawm cov silicity nce, thiab oxidation tiv taus nce.
Lub zog ntawm Andalusite kis yog vim kev qhia txog ntawm Andalusite aggregate, uas nce nws lub zog tom qab qhov kub. Andalusite tuaj yeem tsim cov mullite thib ob tom qab decomposition, uas tuaj yeem txhawb kev sib xyaw ua ke thiab lwm cov ntaub ntawv raw, yog li muaj zog txhim kho lub zog kub ntawm lub Castable. Ntxiv mus, nrog rau kev sib ntxiv ntawm cov Andalusite sib sau ua ke, lub Sio2 tsim tawm tom qab Andalusite Secomposition kuj nce ntxiv, thiab lub zog me me thiab kub siab dua.
Cov kev ua tau zoo ntawm Andalusite Castable yog zoo heev nyob rau hauv cov kub ua hauj thiab thermal poob siab kuj. Hauv cov cheeb tsam uas muaj kub kub loj erosion, Andalusite Casable yog qhov kev xaiv zoo.
