fused cam khwb cia zirconia corundum cibyog ua los ntawm cov khoom zoo purified raw khoom, siv lub tshuab hluav taws xob tshwj xeeb arc rauv thiab cov txheej txheem oxidation ntev. Cov txheej txheem no yuav luag tsis muaj kuab paug los ntawm electrode. Vim yog cov txheej txheem oxidation casting thiab kev siv cov khoom siv high-purity, cov khoom siv fused zirconium corundum peb tsim muaj kev tiv thaiv zoo heev rau kev yaig ntawm iav kua thiab muaj kuab paug tsawg rau cov kua iav.
Raws li cov ntsiab lus sib txawv ZrO2, fused cam khwb cia zirconia corundum cov khoom tau muab faib ua peb hom: 41 # zirconia corundum bricks, 36 # zirconium corundum cib thiab 33 # zirconium corundum cib. Tsis tas li ntawd, raws li cov txheej txheem tsim khoom ntawm AZS36 thiab AZS33, cov ntsiab lus ntawm cov khoom siv tshuaj sib xws ntawm Si02 thiab Na2O raug txo qis, thiab ob yam khoom, 36 # silicon low sodium zirconium corundum cib thiab 33 # silicon low sodium zirconium corundum cib. raug tsim. Cov tsib yam khoom no tau muab cais ntxiv raws li txoj kev sib txawv ntawm qhov sib txawv, uas tuaj yeem ua tau raws li kev siv sib txawv ntawm cov khoom siv melting thiab casting series cov khoom hauv iav furnaces.
Cov laj thawj tseem ceeb vim li cas fused zirconia corundum cib muaj qhov ua haujlwm zoo rau iav kua yaig:
① Lub ntsiab siv lead ua theem hauv zirconium corundum cib yog corundum thiab baddeleyite uas nyob sib ze. Ob leeg siv lead ua theem muaj qhov zoo corrosion kuj.
② Lub iav theem nyob rau hauv zirconium corundum cib yog ntim ntawm cov theem saum toj no siv lead ua. Cov iav theem no yog eroded los ntawm kub kub los ua albite iav nrog viscosity siab heev. Vim tias qee qhov nyiaj ntawm ZrO2 yog yaj hauv nws, viscosity siab dua. Cov txheej no yog siab. Cov iav viscous tseem nyob rau saum npoo ntawm lub cib thiab tsis yooj yim rau kev sib kis, yog li tiv thaiv lub cib lub cev.
Vim qhov zoo li saum toj no, fused cam khwb cia zirconia corundum cib tsis tsuas yog siv nyob rau hauv high-kub, hnyav corroded cheeb tsam nyob rau hauv kev sib cuag nrog iav kua, tab sis kuj lug siv nyob rau hauv lub superstructure ntawm iav melting furnaces.
1. Cam khwb cia 41# zirconia corundum cib;
AZS41 yog qib siab tshaj plaws oxidation txoj kev fused cam khwb cia zirconia corundum cib, uas muaj lub siab tshaj plaws tiv thaiv rau iav kua corrosion thiab zoo heev muaj kuab paug rau iav kua. Nws yog qhov tsim nyog rau qhov chaw ntawm cov iav furnaces uas yuav tsum tau tshwj xeeb tshaj yog corrosion kuj, xws li tag nrho cov hluav taws xob melting furnaces, kua tunnels, kiln sills, bubbling bricks, ces kaum cib ntawm qhov chaw nres nkoj noj, thiab lwm yam.
2. Cam khwb cia 36# zirconia corundum cib;
AZS36 yog tus qauv oxidation txoj kev fused-cam khwb cia zirconia corundum cib, uas muaj cov yam ntxwv ntawm tshwj xeeb siab tiv thaiv iav kua yaig thiab tsis muaj paug ntawm iav kua, thiab kev ua tau zoo ntawm ob yam no yog sib npaug. Nws yog qhov tsim nyog rau qhov chaw hauv iav qhov cub uas muaj kev sib cuag ncaj qha nrog cov kua iav, xws li cov vuas phab ntsa ntawm lub pas dej melting, pavement vuas thiab cov chaw noj mov.
3. Cast 33# zirconium corundum cib;
AZS33 muaj kev ua tau zoo tshwj xeeb hauv kev tiv thaiv kev sib kis ntawm cov kua iav. Nws muaj qhov me me heev ua rau pob zeb, npuas thiab matrix iav theem nag lossis daus hauv iav. Nws yog tsim rau cov qauv sab saud ntawm lub pas dej ua ke, cov vuas phab ntsa ntawm lub pas dej ua haujlwm, cov vuas pavement thiab forehearth, thiab lwm yam.
