High-alumina bricks muaj ntau yam kev siv, tab sis nyob rau hauv cov txiv qaub kiln, lawv tsuas yog siv rau masonry high-temperature aav thiab firing aav.
High alumina bricks use bauxite clinker as the main raw material, which is Al2O3>55 feem pua, ntau theem particle ratio, ntxiv los ntawm tshwj xeeb additives, siab molding, kub kub firing, yog ib tug refractory khoom siv rau masonry moj tej tawg rauv hauv ob sab phlu.
Lawv muab faib ua plaub qib raws li cov ntsiab lus ntawm Al2O3: super cib muaj cov ntsiab lus Al2O3 ntau dua 80 feem pua; thawj qib cib muaj Al2O3 cov ntsiab lus ntawm 75 feem pua -80 feem pua ; ob-qib bricks muaj Al2O3 cov ntsiab lus ntawm 65 feem pua -75 feem pua ; cov cib qib peb yog Al2O3 cov ntsiab lus ntawm 55 feem pua -60 feem pua ;
1. Refractoriness
Lub refractoriness ntawm high-alumina cib yog siab dua li cov av nplaum cib thiab semi-silica cib, ncav cuag 1750 ~ 1790 degree, uas belongs rau cov ntaub ntawv siab heev refractory.
2. Load softening kub
Vim tias Al2O3 siab nyob rau hauv cov khoom siv alumina siab, tsawg impurities thiab tsawg fusible iav lub cev, lub softening kub nyob rau hauv load yog siab dua li cov av nplaum cib, tab sis vim mullite crystals tsis tsim ib tug network qauv, softening kub nyob rau hauv load yog tseem qis dua. tshaj li ntawm silica bricks.
3. Slag tsis kam
Muaj ntau Al2O3 nyob rau hauv siab alumina cib, uas nyob ze rau nruab nrab cov ntaub ntawv refractory, thiab muaj peev xwm tiv taus qhov yaig ntawm acidic slag thiab alkaline slag.
High-alumina thermal rwb thaiv tsev bricks yog siv rau thermal rwb thaiv tsev txheej los yog txheej feem ntau siv nyob rau hauv industrial kilns, thiab tsis nyob rau hauv kev sib cuag nrog slag thiab molten khoom. Lub teeb yuag mullite cib muaj kev ua tau zoo heev thiab tuaj yeem siv rau thermal rwb thaiv tsev txheej ntawm cov chaw tsim khoom hauv metallurgy, petrochemical, cov ntaub ntawv hauv tsev, ceramics thiab lwm yam lag luam, nrog rau cov txheej txheem ua haujlwm hauv kev sib cuag nrog cov nplaim taws, thiab qhov kub yuav tsum tsis txhob muaj. siab tshaj 1450 degree. Lub teeb yuag high-alumina cib feem ntau yog siv rau cov txheej txheem thermal rwb thaiv tsev thiab qhov chaw uas tsis muaj qhov kub thiab txias yaj yaig thiab yaig. Piv txwv li, qhov kub yuav tsum tsis txhob siab tshaj 1350 degree thaum sib cuag nrog cov yaj.
Muaj ntau qhov tshwj xeeb thiab qhov ntau thiab tsawg ntawm lub teeb yuag high-alumina cib, xws li cov qauv sib txawv loj T-3, cov nplais zoo li cov cib, cov cib cib, cov cib cib, thiab lwm yam, nrog rau qee yam khoom tshwj xeeb zoo li . Thaum ua lub teeb yuag high-alumina cib ntawm ntau qhov sib txawv Kev xaiv ntawm nias lub pob zeb pwm txawv, xws li cov khoom tshwj xeeb tsis zoo li lub teeb yuag high-aluminium cov khoom, nws yog ib qho tsim nyog yuav tsum tau rov tsim kho cov nias cib pwm rau kev tsim tawm.
