Corundum cib yog ib lo lus dav dav rau refractory cib. Corundum bricks tau muab faib ua ntau qib thiab sib txawv corundum cov ntaub ntawv.
Feem ntau, refractory bricks nrog txhuas cov ntsiab lus ntau dua 85 feem pua yog hu ua corundum bricks, thiab corundum tuaj yeem muab faib ua xim av corundum, dawb corundum, thiab tabular corundum. Yog li ntawd, muaj ntau hom corundum cib, qee qhov muab faib raws li cov ntsiab lus txhuas, qee qhov muab faib raws li qhov sib txawv ntawm qhov sib txawv; muaj cov refractory cib sib xyaw, muaj corundum cib nrog ntau txoj kev sib txawv; muaj hnyav thiab lub teeb corundum cib.
Corundum bricks nrog sib txawv substrates yog tsim raws li kev siv ib puag ncig ntawm qhov sib txawv ntawm qhov kub thiab txias, thiab feem ntau, cov qib sib txawv ntawm corundum bricks yog ua raws li cov ntsuas ntawm cov chaw tsim khoom. Composite corundum bricks muaj xws li xim av corundum thiab silicon carbide composite cib, corundum thiab silicon nitride composite cib, nrog rau dawb corundum, tabular corundum thiab mullite puas corundum mullite cib, corundum mullite cib kuj. Muaj lub teeb yuag, muaj qhov sib txawv loj ntawm qhov ntom ntom, muaj corundum cib nrog qhov sib txawv ntawm 1.5, 2.8-3.4; tseem muaj corundum refractory bricks compounded nrog chrome, chrome corundum refractory cib feem ntau yog siv nyob rau hauv khib nyiab incinerators hauv ob sab phlu.
Corundum bricks muaj cov ntsiab lus txhuas sib txawv, thiab cov ntsiab lus txhuas nyob nruab nrab ntawm 85-98 feem pua. Corundum bricks nrog cov ntsiab lus ntawm ntau tshaj 95 feem pua yog cam khwb cia thiab tsim. Lawv feem ntau yog siv rau hauv iav kiln linings thiab yog kim heev. Lawv tsuas yog siv nyob rau hauv qab ntawm iav kiln yog resistant rau acid corrosion. Muaj AZS corundum cib, corundum mullite cib thiab lwm yam.
Yog hais tias corundum mullite cib yog lub teeb yuag, nws tau tsim thiab txiav rau hauv cov duab uas yuav tsum tau ua, thiab qhov ntom ntom feem ntau yog nyob ib ncig ntawm 1.5. Nws tuaj yeem siv rau hauv cov txheej txheem kub kub rwb thaiv tsev lossis ncaj qha rau hauv cov txheej txheem ua haujlwm, feem ntau yog nyob rau hauv ob sab ntawm lub teeb kilns. Xws li shuttle kiln hauv ob sab phlu thiab qee lub teeb qhov cub.
Qhov hnyav corundum cib yog siv dav heev, tab sis nws nyob ntawm qhov kub thiab yaig ntawm qhov sib txawv kiln linings. Cov khoom uas muaj qhov kub thiab txias heev thiab ib puag ncig hnyav yuav siv cov cib dawb corundum uas muaj qhov ntom ntom saum 3. 0, lossis corundum mullite composite cib. Cov cib sib xyaw ua ke nrog corundum thiab silicon nitride feem ntau yog siv rau lub qhov rooj rauv. Cov cib zoo li no yuav tsum muaj lub pas dej nitriding, thiab cov txheej txheem ntau lawm txawv ntawm cov txheej txheem ntawm corundum composite xim av corundum cib.
Corundum bricks, corundum composite silicon carbide cib, thiab corundum mullite cib yog tag nrho cov sintered ntawm kub.
Yog li ntawd, corundum bricks tsuas yog ib lo lus dav dav, thiab muaj ntau yam corundum cib ntawm cov khoom sib txawv; tus nqi kuj txiav txim siab los ntawm cov ntsiab lus txhuas sib txawv, ntau qhov sib txawv thiab ntau txoj kev tsim khoom.
