Lub ntsiab lus xaus yog tias Silicon Carbide (SiC) 88 thiab 90 yog cov qib zoo tshaj plaws rau niaj hnub steelmaking thiab hlau casting nyob rau hauv 2026. Tsis zoo li kim high -purity ceramics, Silicon Carbide 88 90 Deoxidizer muaj dual - kev ua haujlwm mechanism rau ib txhij deoxidation thiab recarburization. Los ntawm kev siv Silicon Carbide 88 90 Deoxidizer, foundries tuaj yeem txo tag nrho cov nqi hlau los ntawm 15-20% thaum muab lub zog exothermic rau yaj, ua rau nws hloov pauv zoo tshaj plaws rau Ferrosilicon.
1. Txhais cov khoom: Silicon Carbide yog dab tsi?
Silicon Carbide (SiC)yog lub siab -kev ua tau zoo hluavtaws ua los ntawm quartz xuab zeb thiab roj av coke nyob rau hauv lub cub hluav taws xob tiv thaiv. Thaum muaj ntau tus koom nrog SiC nrog kim semiconductors lossis precision ceramics, nws qhov kev cuam tshuam tseem ceeb tshaj plaws yog nyob rau hauvmetallurgy.
Puas yog Silicon Carbide koom nrog tsev neeg ceramic?Yog, nws yog ib qho kev ua haujlwm siab heev ceramic. Txawm li cas los xij, rau steelmakers,Silicon Carbide 88 90 DeoxidizerNws muaj nuj nqis ntau dua rau nws cov tshuaj reactivity tshaj nws cov ceramic hardness. Nws muaj lub siab melting point thiab tshwj xeeb thermal conductivity, tso cai rau nws mus hnov mob tam sim ntawd thaum ntxiv rau molten hlau los yog hlau.
2. Lub Hwj Chim ntawm "Sub-90" Qib: Vim li cas 88 & 90 SiC?
Lub sintering ntawm roj teeb cov ntaub ntawv tshwm sim nyob rau hauv loj heev qhov cub los yog cov menyuam hearth kilns. Ntawm no,Silicon Carbide 88 90yog siv nyob rau hauv ntau yam tseem ceeb:
Hauv xyoo 2026 kev ua lag luam, cov neeg yuav khoom muaj txiaj ntsig tau hloov pauv ntawm 95% + SiC thiab tsom mus rauSilicon Carbide 88 90 Deoxidizer. Nov yog vim li cas cov qib no yog qhov kev xaiv zoo tshaj plaws:
A. Qhov "Golden Ratio" ntawm Purity thiab Nqi
Rau deoxidation nyob rau hauv EAF (Electric Arc Furnaces) los yog Converters, purity ntawm 88% mus rau 90% muab cov tshuaj tiv thaiv zoo tshaj plaws. SivSilicon Carbide 88 90 Deoxidizerxyuas kom meej tias koj tsis them nyiaj ntau dhau rau "dhau-purity" uas tsis txhim kho cov hlau qhov kawg.
B. Dual-Action Performance
Txhua ton ntawmSilicon Carbide 88 90 Deoxidizermuab kwv yees li 60% Silicon thiab 30% Carbon.
- Deoxidation: Nws reacts ntau aggressively nrog yaj oxygen dua Ferrosilicon, tsim kom huv si yaj.
- Recarburization: Cov pa roj carbon sib xyaw ua ke muaj qhov rov qab los ntawm ntau dua 90%, tso cai rau koj kom txo tau koj cov nyiaj siv hluav taws xob sib cais.
3. Kev sib piv: SiC 88 90 vs. Ferrosilicon 75
Txhawm rau pom cov nyiaj khaws cia, xav txog yuav ua li cas covSilicon Carbide 88 90 Deoxidizeroutperforms tsoos alloys:
Table 1: Refractory Performance Matrix (SiC vs. Alumina)
| Metric | Ferrosilicon 75 (FeSi 75) | Silicon Carbide 88 90 Deoxidizer |
| Lub luag haujlwm tseem ceeb | Silicon Ntxiv | Deoxidation + Recarburization |
| Kub cuam tshuam | Txias nyhuv | Exothermic (Ntxiv Thaum tshav kub kub) |
| Slag Quality | Thicky thiab nplaum | Dej thiab tswj tau |
| Txuag tag nrho | Tus nqi pib | 15% - 20% Txo |
4. Qhov twg yog "Sub-90" Silicon Carbide siv?
CovSilicon Carbide 88 90 Deoxidizeryog ntau yam workhorse ntawm kev lag luam:
- Steelmaking (EAF & Hloov): Siv los tswj cov qib oxygen thiab ntxiv tshuaj lom neeg lub zog rau lub qhov cub.
- Hlau Casting: Ua raws li lub zog inoculant, txhawb kev tsim cov graphite thiab txo "chij" hauv nyias- cov phab ntsa castings.
- Foundry Cupolas: Ntxiv rauBriquette daim ntawvtswj cov qib silicon thiab txhim kho qhov kub thiab txias.
5. FAQ: Cov Kws Qhia Txog Kev Muag Khoom
Q: Vim li cas kuv thiaj yuav tsum xaiv SiC 88 dhau SiC 90?
A:SiC 88 yog qhov kawg "Budget King." Yog tias koj qib steel muaj kev kam rau siab dua rau cov kab kawm,Silicon Carbide 88 Deoxidizermuab tus nqi qis tshaj plaws -ib - tuj ntawm silicon rov qab.
Q: Puas yog cov impurities hauv qib 88/90 muaj teeb meem?
A:Tsis yog. Ntawm ZhenAn, peb nruj me ntsis tswj Al2O3 thiab Fe2O3 qib hauv pebSilicon Carbide 88 90 Deoxidizer. Cov impurities me yog yooj yim absorbed rau hauv lub slag thiab tsis cuam tshuam qhov purity ntawm koj cov khoom kawg.
Q: Koj yuav tiv thaiv plua plav thaum them nyiaj li cas?
A:Peb muab covSilicon Carbide 88 90 Deoxidizerhauv siab -densityBriquettes (50 hli). Cov no yog nias nyob rau hauv 10,000 tons ntawm quab yuam, kom ntseeg tau tias lawv ncav cuag cov hlau molten yam tsis tsim cov plua plav lossis ntab ntawm cov slag.
