Cov Lus Qhia Yooj Yim Ua Ntej Cov Khoom Cuav Refractory Cib

Refractory cib raug xa mus ua hluav taws xob cib. Refractory ua los ntawm cov av nplaum refractory lossis lwm yam khoom siv refractory. Daj daj lossis xim av. Nws yog tsuas yog siv rau kev tsim cov txheej txheem smelting, thiab tuaj yeem tiv taus siab kub ntawm 1,580 ℃ -1,770 ℃. Kuj tseem hu ua firebrick. Khoom siv refractory nrog qee qhov qauv thiab qhov loj me. Raws li cov txheej txheem kev npaj, nws muaj peev xwm muab faib ua cov cib ua hluav taws kub, tsis kub hnyiab cib, cib fused (fused cam khwb cia), refractory thiab tshav kub insulating cib; raws li cov duab thiab qib loj, nws tuaj yeem muab faib ua cov cib txheem, cib zoo tib yam, thiab cov cib tshwj xeeb. Nws tuaj yeem siv los ua cov cuab yeej hluav taws xob kub thiab cov ntaub ntawv tsim kho rau lub tsev kub thiab ntau yam khoom siv thermal, thiab tuaj yeem tiv taus ntau yam kev hloov ntawm lub cev thiab tshuaj lom neeg thiab kev siv tshuab ntawm lub siab kub. Piv txwv, refractory av nplaum cib, siab alumina cib, silica cib, magnesia cib, thiab lwm yam.
