Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, tib neeg qhov kev thov rau cov khoom siv refractory kuj tau nce siab thiab siab dua. Cov ntaub ntawv refractory, raws li lub npe qhia, xa mus rau cov ntaub ntawv uas muaj cov khoom xws li tsis-melting ntawm qhov kub thiab txias, tsis brittleness, thermal shock tsis kam, corrosion kuj thiab thermal rwb thaiv tsev. Nws yog dav siv hauv metallurgy, kev tsim kho, ceramics, tshuaj lom neeg kev lag luam thiab lwm yam kev lag luam.
Siv cov hlau ua piv txwv, ntau cov khoom siv refractory sib txawv yog siv rau hauv cov txheej txheem steel. Feem ntau ntawm cov no yog sintered cib, hluavtaws corundum, ferrochromium los yog magnesia bricks, pressurized aluminium bricks thiab ntau hom kev ncua thiab xim.
Hauv qee qhov kev tsim kho, cov khoom siv hluav taws xob kuj tseem xav tau, xws li cov ntaub ntawv rwb thaiv tsev hauv qab daus ntawm cov tsev siab siab, thiab ntau yam khoom siv hluav taws kub.
Hauv kev lag luam ceramic, cov ntaub ntawv refractory kuj tau siv dav. Kev tua hluav taws thiab sintering ceramic refractory cov ntaub ntawv tuaj yeem tsis tsuas yog txo cov roj noj, tab sis kuj txo cov pa phem.
Hais txog tshuaj tiv thaiv ib puag ncig, cov ntaub ntawv refractory kuj yuav tsum tau siv. Kev khaws cia thiab cov tshuaj tiv thaiv ntawm qee yam tshuaj xws li cov kua qaub siab thiab cov concentrated alkali yuav tsum tau siv cov khoom siv acid- thiab alkali-resistant kom muaj kev nyab xeeb ntawm cov tshuaj tiv thaiv.
Cov ntaub ntawv refractory muaj ntau yam kev siv thiab muaj feem xyuam nrog tib neeg lub neej. Nyob rau hauv lub neej yav tom ntej, nrog kev nce qib ntawm thev naus laus zis, tib neeg cov kev xav tau ntawm cov khoom siv refractory yuav dhau los ua siab dua. Nws vam tias kev lag luam cov khoom siv refractory tuaj yeem txuas ntxiv kom loj hlob thiab txhim kho thiab ua kom muaj txiaj ntsig zoo rau kev tsim kho kev lag luam.
