Lub luag haujlwm ua haujlwm ntawm Silicon Carbide 88 nyob rau hauv Refractory Linings
Silicon carbide 88 yog ib nrab - purity refractory qib uas muaj kwv yees li 88% SiC. Tsis zoo li rwb thaiv tsev refractories, uas feem ntau txo cov cua sov poob, SiC 88 feem ntau ua raws li cov txheej txheem refractory: nws nqa load ntawm kub, tiv taus abrasion los ntawm tsiv cov ntaub ntawv thiab gases, kis tshav kub sib npaug los ntawm high thermal conductivity, thiab withstands tshuaj tua los ntawm slag, molten hlau thiab corrosive gases. Cov khoom hauv ob sab phlu ua los ntawm SiC 88 feem ntau yog siv los ua lub ntsej muag ua haujlwm ncaj qha rau kev ua haujlwm hnyav.
Cov khoom tseem ceeb cuam tshuam rau kev ua haujlwm hauv ob sab phlu
| Khoom | Tus cwj pwm ntawm SiC 88 |
|---|---|
| SiC cov ntsiab lus | Txog 88% |
| Hardness | hmo 9.5 |
| Thermal conductivity | Siab - txo cov thermal gradients thiab kub- qhov chaw pheej hmoo |
| Thermal shock tsis kam | Zoo heev - zam cov cua kub ceev thiab cua txias |
| Oxidation cwj pwm | Ua ib txheej tiv thaiv SiO2 ntawm qhov kub thiab txias, ua kom oxidation ntxiv; qhov kev pab cuam qhov kub thiab txias yog qis dua hauv cov huab cua oxidizing zoo dua li hauv inert lossis txo cov xwm txheej |
| Tshuaj stability | Zoo tiv taus rau feem ntau slags thiab molten hlau; Cov kab mob hnyav heev yuav xav tau ntau dua - qib purity |
Nco tseg ntawm qhov kev pabcuam kub: qhov siab tshaj plaws ua haujlwm kub ntawm SiC-raws li refractories nyob ntawm huab cua. Nyob rau hauv inert los yog txo tej yam kev mob SiC yuav siv tau nyob rau hauv high kub, thaum nyob rau hauv oxidizing atmospheres lub tswv yim txwv yog qis dua; qhov tsim nyog qhov siab tshaj plaws kev pab cuam kub rau ib cheeb tsam cua sov thiab cua yuav tsum tau lees paub nrog tus tsim khoom refractory.
Hom ntawv hauv ob sab hauv kev tsim kho
Cib thiab blocks- preformed SiC 88 cib nteg nrog refractory mortar rau hearths, sidewalls thiab burner quarls; standard dimensions yooj yim installation.
Castables thiab ramming mix- SiC 88 grain bonded nrog siab -kub binders rau cam khwb cia- nyob rau hauv- qhov chaw hauv ob sab phlu nyob rau hauv complex geometries xws li reactor hlab ntsha thiab kiln pem teb; sib koom ua ke- kev tsim kho dawb txo cov ntsiab lus tsis muaj zog.
Daim phiaj thiab cov duab- machined SiC 88 daim hlau rau kiln txee, saggers thiab reactor internals uas yuav tsum tau flatness thiab seem stability.
Kiln rooj tog- txhawb nqa ceramic lossis hmoov loads thaum tua; lub zog zoo-rau- qhov hnyav piv txhim kho lub zog efficiency.
Cov Neeg Sawv Cev Muaj Kev Siv
Steel thiab foundry furnaces - sidewall thiab hearth linings nyob rau hauv kev sib cuag nrog molten hlau.
Iav melting kilns - skid rails thiab feeder channels raug thermal cycling thiab puas.
Ceramic kilns - rhawv thiab setters rau tua cov vuas, huv si thiab technical ceramics.
Cement kilns - burning -zone segments raug rau clinker abrasion thiab kub siab.
Chemical reactors - cov ntaub ntawv ua cov khoom abrasive lossis corrosive thiab gases ntawm qhov kub siab.
Aluminium recycling furnaces - hearth linings resistant rau molten aluminium nkag mus thiab yaig.
Installation thiab Maintenance Considerations
Kev sib koom ua ke yuav tsum txo qhov sib txawv kom tsis txhob muaj cua sov hauv zos; anchoring systems yuav tsum tau sib xws nrog SiC lub thermal expansion; thiab cov mortars sib xws yuav tsum tau siv los ua kom cov pa hauv ob sab phlu- nruj. Kev tshuaj xyuas tsis tu ncua rau spalling lossis tshuaj tua kab mob tso cai rau cov khoom puas raug hloov ua ntej tsis ua haujlwm. Siv SiC 88 cib tuaj yeem nyob rau qee kis tau raug tsoo thiab rov siv dua li sib sau ua ke hauv qis dua -cov dej num monolithic refractories.
Cov lus nug nquag
Q1: SiC 88 puas tuaj yeem ua haujlwm tsis tu ncua saum 2,000 degree?
Hauv inert lossis txo cov cua sov SiC refractories tuaj yeem ua haujlwm ntawm qhov kub siab heev. Nyob rau hauv cov huab cua oxidizing muaj zog qhov kev txwv qhov kev pab cuam tsawg dua, yog li qhov siab tshaj plaws kev pab cuam qhov kub thiab txias yuav tsum tau lees paub nrog cov neeg tsim khoom refractory rau cov cua tshwj xeeb thiab kev thauj khoom.
Q2: Puas yog SiC 88 zoo dua li alumina bricks rau thermal shock resistance?
Feem ntau yog - thermal conductivity ntau dua thiab qis dua thermal expansion ntawm SiC 88 muab nws zoo dua rau kev hloov kub ceev.
Q3: Cov duab dab tsi ntawm SiC 88 siv rau hauv qhov cub?
Cib, monolithic castables, daim hlau thiab kev cai - cov rooj tog zaum ua tshuab xws li rhawv thiab setters.
Q4: Puas yog SiC 88 cuam tshuam nrog molten txhuas?
Nws qhia tau hais tias zoo tiv thaiv rau molten aluminium; nyob rau hauv cov xwm txheej hnyav heev, siab dua - qib purity lossis cov txheej tiv thaiv yuav raug txiav txim siab.
Q5: Vim li cas qhov nruab nrab - qib purity zoo li SiC 88 xaiv es tsis txhob siab dua - purity SiC?
Qhov twg daim ntawv thov tsis xav tau ultra- qib impurity tsawg, qib 88% muab kev ua tau zoo refractory ntawm tus nqi qis.
Q6: SiC 88 puas tuaj yeem kho lossis rov ua dua tshiab?
Cov seem puas tuaj yeem hloov tau xaiv, thiab siv SiC 88 cib tuaj yeem raug crushed thiab rov qab siv dua li sib sau ua ke hauv qis dua -cov haujlwm monolithic daim ntawv thov.
