Corundum Cib yog dab tsi

Corundum cib hais txog cov khoom siv refractory nrog alumina cov ntsiab lus ntau dua 90% thiab corundum ua lub ntsiab siv lead ua theem. Chav tsev kub compressive zog (txog 340MPa). Qhov pib kub rau siab load softening (ntau tshaj 1700 degree). Zoo tshuaj stability, muaj zog tiv taus acidic los yog alkaline slag, hlau, thiab iav kua. Lub thermal shock stability yog cuam tshuam nrog nws lub koom haum qauv. Cov khoom ntom ntom muaj qhov zoo corrosion kuj, tab sis tsis zoo thermal shock stability.
Corundum bricks tau dav siv los ua cov ntaub ntawv hauv ob sab hauv petrochemical thermal units nrog kev kub siab, siab siab, tshuaj yaig, thiab kev siv tshuab hnyav. Nrog rau kev nce qib ntawm kev tsim cov thev naus laus zis hauv kev lag luam petrochemical, ntau cov txheej txheem tshiab thiab thev naus laus zis tau raug coj los siv hauv kev tsim khoom. Txhawm rau ua tiav cov hom phiaj ntawm kev thauj khoom siab, lub voj voog ntev, kev siv hluav taws xob tsawg, thiab cov khoom siv qis, ntxiv rau kev kho dua tshiab ntau yam khoom siv thermal, cov kev xav tau siab dua tau muab tso rau pem hauv ntej rau cov ntaub ntawv hauv ob sab phlu ntawm ntau yam khoom siv thermal. Yog li ntawd, ib tug series ntawm chromium corundum cov khoom uas zoo dua kub tsis kam thiab corrosion kuj tau tsim kom tau raws li cov kev xav tau ntawm petrochemical kev lag luam.
