Dab tsi yog qhov txawv ntawm siab alumina cib thiab av nplaum cib

ib. Lub refractoriness ntawm high-refractory alumina cib yog siab dua li cov av nplaum cib thiab semi-silica cib, ncav cuag 1750 ~ 1790 ℃, uas yog qib high-qib refractory khoom.

b. Load softening kub Vim tias cov khoom siv aluminium siab muaj Al2O3 siab, tsawg impurities, thiab tsawg fusible iav, load softening kub yog siab tshaj li cov av nplaum cib, tab sis vim mullite crystals tsis tsim ib tug network qauv, lub load softening kub yog tseem tsis raws li. siab li silica cib.

c. Lub slag kuj siab alumina cib muaj ntau dua Al2O3, uas yog ze rau nruab nrab cov ntaub ntawv refractory, thiab tuaj yeem tiv taus cov kua qaub slag thiab alkaline slag. Vim tias nws muaj SiO2, lub peev xwm los tiv thaiv alkaline slag tsis muaj zog dua li cov kua qaub slag. qee. Feem ntau yog siv rau hauv ob sab phlu ntawm blast furnaces, kub moj tej tawg qhov cub, hluav taws xob rauv saum, blast furnaces, reverberatory furnaces, thiab teb kilns. Tsis tas li ntawd, siab alumina cib kuj tau dav siv los ua qhib hearth regenerative checker cib, plugs rau pouring systems, nozzle cib, thiab lwm yam.

Txawm li cas los xij, tus nqi siab ntawm alumina cib yog siab dua li cov av nplaum cib, yog li nws tsis tsim nyog siv cov alumina cib siab uas cov av nplaum cib tuaj yeem ua tau raws li qhov yuav tsum tau ua. Tus nqi ntawm high-alumina bricks feem ntau txawv heev raws li cov ntsiab lus ntawm aluminium, thiab cov nyhuv ntawm kev siv kuj txawv heev.
