Tsawg-qib silicon carbide yog dav siv los txo qhov kev yaig ntawm cov ntaub ntawv refractory, tshwj xeeb tshaj yog nyob rau hauv siab - coj ib puag ncig xws li hlau khiav, slag kab, thiab teb kilns.
Nyob rau hauv cov ntaub ntawv no, refractory linings yog tas li raug rau molten theem, abrasive hais, thiab tshuaj tua kab mob, uas ua rau kom cov ntaub ntawv poob thiab shorten lub neej kev pab cuam. Los ntawm kev txhim kho kev puas tsuaj thiab kev ruaj ntseg ntawm cov qauv, qis- qib silicon carbide muab cov tswv yim thiab tus nqi- siv tau zoo rau cov teeb meem yaig no.
Dab tsi yog Qib -Qib Silicon Carbide?
Tsawg-qib silicon carbidefeem ntau yog hais txog silicon carbide nrog qis SiC cov ntsiab lus thiab siab dua ntawm impurities xws li cov pa roj carbon monoxide dawb, silica, hlau oxide, alumina, los yog lwm yam ntxhia cov khoom piv nrog qib siab - purity.
Los ntawm qhov kev xav ntawm kev tsim khoom refractory, qis -qib silicon carbide tsis yog ib qho qis dua - tus nqi hloov. Nws tus nqi nyob ntawm seb nws siv li cas hauv kev tsim. Rau ntau cov khoom siv refractory, tshwj xeeb tshaj yog qhov kev tswj hwm tus nqi thiab hnav tsis kam yuav tsum sib npaug, qis - qib silicon carbide tseem tuaj yeem muab cov txiaj ntsig kev ua tau zoo.
Yog vim li cas Erosion tshwm sim nyob rau hauv cov ntaub ntawv refractory
Erosion nyob rau hauv cov ntaub ntawv refractory feem ntau tshwm sim los ntawm kev sib xyaw ntawm cov neeg kho tshuab hnav thiab tshuaj tua kab mob.
Tej yam ua rau muaj xws li:
- nruam scouring los ntawm molten hlau los yog slag
- abrasive txav ntawm cov khoom siv
- Kev nkag mus ntawm slag rau hauv cov qauv refractory
- oxidation thiab tsis muaj zog ntawm matrix
- rov ua dua thermal cycling uas ua rau qhov chaw ruaj khov
Thaum lub matrix ua tsis muaj zog los yog ntxeem tau ntau dua, molten theem tuaj yeem tua lub hauv ob sab phlu yooj yim dua, ua kom cov khoom poob.
Tsawg npaum li cas -Qib Silicon Carbide pab txo kev yaig
Lub ntsiab yog vim li cas silicon carbide siv nyob rau hauv refractories yog nws zoo heev tsis kam mus hnav, siab thermal conductivity, thiab txheeb ze tshuaj stability nyob rau hauv ntau yam kev pab cuam. Txawm tias thaum qib qis dua, nws tseem tuaj yeem txhim kho kev yaig tsis kam thaum xaiv thiab sib xyaw ua ke.
Txhim kho Abrasion Resistance
Silicon carbide yog cov khoom siv tawv. Nyob rau hauv refractory formulations, nws muaj peev xwm txhim kho lub hauv ob sab phlu tiv thaiv abrasive hnav los ntawm slag txav, raw khoom cuam tshuam, los yog siab tshaj - cov lus tshaj tawm.
Rau cov ntawv thov uas cov txheej txheem yaig suav nrog kev siv tshuab ua kom muaj zog, qis-qib silicon carbide tseem tuaj yeem ua rau muaj qhov zoo dua qub thiab hnav qeeb dua.
Zoo dua Slag Resistance nyob rau hauv lub tswv yim tej yam kev mob
Hauv ntau lub tshuab refractory, erosion tsis yog lub cev hnav xwb. Nws feem ntau txuas rau slag nkag mus thiab matrix nres.
Tsawg-qib silicon carbide tuaj yeem pab tau los ntawm:
- txo qhov qhib porosity thaum muab qhab nia zoo
- txhim kho matrix compactness

Txawm hais tias nws yuav tsis phim qhov kev ua tau zoo ntawm hwm SiC hauv txhua qhov chaw hnyav, nws tseem tuaj yeem txhim kho kev tiv thaiv piv nrog cov qauv uas tsis siv SiC txhua.
Txhim kho Thermal conductivity
Cov thermal conductivity ntau dua yuav pab txo qis hauv zos overheating thiab thermal gradients nyob rau hauv cov ntaub ntawv refractory.
Qhov no tuaj yeem txhim kho cov qauv kev ruaj ntseg thiab txo qhov tsim ntawm cov chaw tsis muaj zog uas yooj yim dua eroded. Nyob rau hauv qhov chaw ua haujlwm kub - lub ntsej muag degradation yog txuas nrog thermal stress, silicon carbide tuaj yeem pab tswj qhov chaw ua haujlwm ruaj khov dua.
Kev them nyiaj yug rau Stronger Bonding Structure
Hauv qee cov khoom siv refractory, qis-qib silicon carbide tuaj yeem txhim kho tag nrho cov microstructure thaum siv nrog txoj cai khi thiab sib sau ua ke.
Nws tuaj yeem ua rau:
- denser ntim
- txo tawg propagation
- txhim kho tsis kam mus rau lub zos ntxuav tawm
Nws cov nyhuv tsis yog tsuas yog txiav txim los ntawm purity, tab sis kuj los ntawm particle loj, tis, thiab compatibility nrog rau tag nrho cov formulation.
Qhov tsawg-Qib Silicon Carbide feem ntau siv
Tsawg-qib silicon carbide feem ntau yog siv rau hauv cov khoom siv refractory uas tus nqi- kev ua tau zoo sib npaug tseem ceeb dua qhov kev coj dawb huv heev.
Cov ntawv thov ib txwm muaj xws li:
- castables rau abrasion-cov cheeb tsam tiv taus
- ramming sib tov
- phom phom
- kais qhov thiab cov ntaub ntawv khiav
