Tshwj xeeb zoo li High alumina cib (Qib I)

Yog tias Al2O3 cov ntsiab lus siab dua 90%, nws hu ua corundum cib. Vim muaj kev sib txawv, cov qauv ntawm ntau lub teb chaws tsis zoo ib yam. Piv txwv li, cov teb chaws Europe tau teev tseg tias qhov qis dua ntawm Al2O3 cov ntsiab lus rau high-alumina refractories yog 42%. Nyob rau hauv Suav teb, siab alumina cib feem ntau yog xa mus rau refractory cib nrog cov ntsiab lus Al2O3 ntau dua 48%. Lawv feem ntau yog ua los ntawm ntuj qib high-qib bauxite, uas muaj cov minerals xws li diaspore, bomerite, kaolinite, thiab lwm yam. Mos los yog semi-mos av nplaum yog ntxiv rau high-alumina clinker raws li ib tug binder pib batching thiab sib tov, thiab ces nws. yog tsim, qhuav, thiab thaum kawg raug rho tawm haujlwm. Lub refractoriness ntawm siab alumina cib yog hais txog 1770 ℃, thiab lub load softening kub yog 1420 ℃ -1550 ℃. Feem ntau cov alumina bricks yog LZ-80, LZ-75, LZ-65, LZ-55, LZ-48, thiab lwm yam. Nws yog siv rau hauv ob sab phlu blast furnace, kub moj tej tawg rauv, ore-kub rauv, hluav taws xob rauv ru tsev, moj tej tawg. rauv, reverberatory rauv thiab rotary kiln. Tsis tas li ntawd, lub siab alumina cib kuj tau siv dav hauv qhov qhib-hearth heat storage checker bricks, plugs for pouring systems, nozzle bricks, etc.
