1, hluav taws ua hauj
Cov hluav taws tsis kam ntawm cov cib no siab dua li ntawm cov av nplaum cib thiab semi-silica cib, ncav 1750 ~ 1790 ℃. Nws belongs rau cov khoom siv zoo zoo refractory. Qhov siab dua ntawm qhov hluav taws kub tsis kam, qhov ua tau zoo dua, thiab tus nqi yuav raug hnyav.
2, thauj khoom kub muag muag
Vim tias lub siab Al2O3 hauv cov khoom lag luam ntawm al-aluminium, qhov ntau ntawm qhov tsis zoo yog me thiab lub fusible iav yog tsim. Yog li ntawd, lub load softening kub yog siab dua li ntawm av nplaum cib.
3.Slag kuj
Cib muaj ntau Al2O3, uas yog ze rau nruab nrab ntawm cov ntaub ntawv refractory nruab nrab, thiab tuaj yeem tiv thaiv qhov yaig ntawm acidic thiab alkaline slag. Vim tias nws muaj SiO2, nws lub peev xwm los tiv thaiv alkaline slag tsis muaj zog dua li ntawm cov kua qaub slag.
Lub cib yog tsuas yog siv rau masonry moj tej tawg ua kom sov, lub pob hluav taws kub tawg, hluav taws xob lub tshuab ua kom sov sab saum toj, tshuab tawg ua kom sov, lub tsev rau hluav taws kub hnyiab thiab ua kom lub tsev roj mentsis. Tsis tas li ntawd, cov cib ntsa kuj tseem siv tau los ua qhib-hearth regenerative lattice cib, ntsaws rau lub tshuab tsis muaj txheej, thiab cov tsis muaj qhov ci ntsa iab. Txawm li cas los xij, tus nqi ntawm lub cib yog siab dua li ntawm cov av nplaum cib, yog li nws tsis tsim nyog siv qhov av uas qhov av nplaum av nplaum tuaj yeem ua tau raws li qhov yuav tsum tau ua.
Cov nyhuv ntawm loj ntawm tus nqi ntawm high-alumina refractory cib Qhov loj ntawm qib siab alumina cib feem ntau muab faib ua cov teb chaws tus qauv, cov duab tshwj xeeb thiab cov duab tshwj xeeb. Qhov loj ntawm lub teb chaws tus qauv yog tsau, thiab cov chaw tsim khoom lag luam tuaj yeem tsim ua ntau, yog li tus nqi kuj tseem qis; thiab qhov loj thiab cov duab ntawm cov duab tshwj xeeb thiab tshwj xeeb tsis tau ruaj khov. Tshwj tsis yog cov qauv ntaub thaiv dav dav, cov lag luam feem ntau yuav tsum kho cov kev tsim khoom. Qhov nyuaj kujnce raws li qhov tsim nyog ntawm cov duab, yog li tus nqi kuj siab.
