Cov ntsiab lus xaus yog tias Silicon Carbide (SiC) yog cov cuab yeej zoo tshaj plaws hauv metallurgical hauv 2026, muab 10-20% txo tus nqi tshaj Ferrosilicon (FeSi). SiC 88/90 muab ob qho txiaj ntsig - kev ua haujlwm ntawm kev sib xyaw deoxidation thiab rov ua dua tshiab thaum ua rau lub zog tseem ceeb hauv cov yaj, ua rau nws muaj txiaj ntsig zoo tshaj plaws hloov pauv rau FeSi niaj hnub EAF thiab converter steelmaking.
1. Silicon Carbide: Lub Multi-Functional Powerhouse
Thaum Ferrosilicon yog ib qho - lub hom phiaj alloy,Silicon Carbide (SiC)yog multi-functional reagent. Nyob rau hauv 2026 lub zog-kev ua lag luam nco qab, lub peev xwm ntawmSIB 88thiabSIB 90los ua peb txoj haujlwm ib txhij tau ua nws qhov kev xaiv thawj zaug rau ZhenAn cov neeg siv khoom thoob ntiaj teb.
- Muaj txiaj ntsig Deoxidation: SiC reacts aggressively nrog yaj oxygen, ua ib tug huv steel chemistry dua li ib txwm txoj kev.
- Integrated Recarburization: Txhua tuj ntawm SiC 90 muab kwv yees li 270kg ntawm cov pa roj carbon monoxide, tshem tawm qhov xav tau ntawm cov khoom siv sib cais, kim recarburizers.
- Thermal Zog Txhaj: Cov tshuaj tiv thaiv ntawm SiC muaj zog exothermic, zoo nce qhov kub ntawm cov hlau molten.
2. Kev sib piv: Vim li cas SiC Outperforms Traditional Alloys
Lub superiority ntawm Silicon Carbide tshaj Ferrosilicon yog rooted nyob rau hauv nws cov tshuaj efficiency thiab thermodynamic zog.
Table 1: Performance Matrix (SiC vs. FeSi)
| Kev ntsuas qhov tseem ceeb | Silicon Carbide 90 | Ferrosilicon 75 | Muaj kev cuam tshuam |
| Lub luag haujlwm tseem ceeb | Deoxidation + Recarburization | Deoxidation nkaus xwb | SiC txuag 20% ntawm cov tshuaj ntxiv |
| Tus nqi Thermodynamic | Exothermic (+ Kub) | Neutral/cooling (-Tshav kub) | SiC txo kev siv hluav taws xob |
| Slag Management | Clean & Fluid Slag | Hnyav, Nplaum Slag | SiC ncua lub neej refractory |
| Nucleation zog | High (muaj zog Inoculant) | Nruab nrab | SiC txhim kho lub zog casting |
| Nqe Stability | High (Stable Supply) | Volatile (Energy Dependent) | SiC muab kev tswj nyiaj txiag zoo dua |
3.Tus nqi-Txuag Dynamics: Cov Ntaub Ntawv Nyiaj Txiag rau SiC 88/90
Nyob rau hauv niaj hnub foundries, kev hloov mus rau Silicon Carbide yog tsav los ntawm cov kab hauv qab. Los ntawm kev hloov ib feem ntawm Ferrosilicon nrog ZhenAn's SiC 88 lossis 90, cov nroj tsuag tuaj yeem ua tiav "Triple-Txuag" cov nyhuv.
- Tus nqi qis dua: SiC 88/90 tsis tu ncua tswj tus nqi sib tw ntau dua piv rau qib siab -qib FeSi 75.
- Txo tus nqi Recarburizer: The carbon recovery from SiC is exceptionally high (often >90%), txiav nyiaj ntau rau anthracite lossis hluavtaws graphite.
- Kev txuag hluav taws xob: Lub zog exothermic tso tawm los ntawm SiC tuaj yeem txo qhov cub "fais fab-" sijhawm los ntawm ob peb feeb rau ib lub tshav kub, txhais ua kev txuag hluav taws xob ntau xyoo.
4. Tswv yim FAQ: Qhov Hloov -Over Guide
Q1: Vim li cas Silicon Carbide 90 ua tau zoo dua Ferrosilicon hauv Hluav Taws Xob Hluav Taws Xob (EAF)?
A1:Qhov laj thawj tseem ceeb yog"Chemical Energy Compensation."SiC 90 tsim cov tshuaj tiv thaiv exothermic thaum lub sij hawm deoxidation, muab cov cua sov ntxiv rau cov yaj thiab ua kom lub zog luv luv - raws sijhawm. Ferrosilicon, los ntawm qhov sib txawv, muab qhov tsis txaus siab rau thermal. Tsis tas li ntawd, SiC 90 muab cov pa roj carbon monoxide zoo heev, kev sib xyaw deoxidation thiab recarburization rau hauv ib kauj ruam.
Q2: Puas yog tus nqi rov qab ntawm Silicon Carbide 88 ruaj khov? Kuv yuav xam npaum li cas?
A2:Raws li cov qauv kev ua haujlwm, Silicon rov qab tus nqi ntawm SiC 88 feem ntau yog80-85%, thaum cov pa roj carbon rov qab ntau dua90%. Vim nws muaj me ntsis impurities siab dua qib 90, peb pom zoo kom ib tug "me- koob, ntau yam- ntxiv" txoj hauv kev pib los txiav txim qhov zoo piv rau koj lub qhov cub tshwj xeeb.
Q3: Koj SiC Briquettes puas puas thaum thauj lossis khaws cia?
A3:Tsis yog. ZhenAn siv high -pressure bonding technology. Peb cov briquettes muaj lub zog txias txias heev (CCS Ntau dua lossis sib npaug li 1500N ib pob), kom ntseeg tau tias lawv tuaj yeem tiv taus ntau lub sijhawm thauj khoom thiab kev thauj mus los yam tsis muaj pulverizing. Qhov no xyuas kom meej them nyiaj thiab muaj plua plav paug tsawg.
Q4: Qhov loj me me cuam tshuam li cas rau kev ua haujlwm deoxidation?
A4:Qhov loj me tseem ceeb heev. Rau induction furnaces, peb pom zoo0-10 hlilos yog1-5 hlinplej kom sai sai. Rau kev ua haujlwm converter,50 hli briquettesyog superior raws li lawv qhov hnyav tso cai rau lawv nkag mus rau slag txheej thiab react ncaj qha nrog cov hlau molten.
Q5: Yuav ua li cas yog metallurgical qib SiC 88 tau damp? Nws puas cuam tshuam rau kev ua haujlwm?
A5:Cov dej noo siab tuaj yeem ua rau hydrogen khaws hauv cov hlau. Thaum SiC nws tus kheej tsis yog -absorbent, noo noo tuaj yeem nkaum ntawm cov khoom. ZhenAn sivwaterproof jumbo hnab nrog yas puab linerlos xyuas kom meej cov khoom nyob twj ywm qhuav txawm tias thaum lub sij hawm transoceanic shipping.
Q6: Puas yog koj tam sim no SiC 88/90 quotes siv tau rau CIF / CFR?
A6:Peb tus qauv quotes yogFOB Tianjin los yog Huangpu. Txawm li cas los xij, vim muaj kev hloov pauv hauv hiav txwv thauj khoom hauv 2026, peb muab -time CIF quotes tiag. Peb pab neeg logistics tuaj yeem xam cov khoom thauj tshiab kawg rau cov chaw nres nkoj loj thoob ntiaj teb los pab koj txiav txim siab koj tus nqi tsaws.
5. Vim li cas thiaj xaiv ZhenAn ua koj tus khub?
