Hauv kev lag luam metallurgical tsis hloov pauv ntawm 2026, steel mills yog nyob rau hauv lub siab loj heev los txhim kho cov nqi raw khoom yam tsis muaj kev cuam tshuam cov tshuaj lom neeg ntawm cov yaj.Silicon Carbide 88 (SiC 88), muaj kwv yees li 85% -88% SiC, tau tshwm sim los ua qhov kev xaiv zoo tshaj plaws rau Ferrosilicon 75 (FeSi 75) rau slag deoxidation thiab alloying.
Los ntawm kev txheeb xyuas cov thermodynamics ntawm cov txheej txheem deoxidation, peb tuaj yeem txheeb xyuas peb txoj hauv kev uas SiC 88 txo qis cov nqi tsim khoom.
1. Superior Deoxidation Efficiency vs. Ferrosilicon
Lub luag haujlwm tseem ceeb ntawm deoxidizer yog tshem tawm cov pa oxygen los ntawm cov hlau molten. Thaum FeSi 75 tso siab rau ntawm silicon, lubCov mis mos Silicon Carbide (SiC)muab ob qho - cov tshuaj tiv thaiv.
Chemical Advantage
Thaum SiC 88 ntxiv rau lub qhov cub lossis lub ladle, nws dissociates rau hauv cov khoom siv silicon thiab carbon.
- Silicon Reaction:Si + 2O → SiO₂ (Forms ruaj khov slag)
- Cov pa roj carbon monoxide:C + O → CO (Gas evolution)
Vim tias cov pa roj carbon kuj ua rau deoxidizer, "Si sib npaug" ntawm SiC 88 yog qhov siab dua nws cov ntsiab lus nominal silicon. Nyob rau hauv lub tswv yim,1 kg ntawm SiC 88 tuaj yeem hloov tau kwv yees li 1.2 txog 1.5 kg ntawm FeSi 75, nyob ntawm cov pa oxygen ntawm cov cua sov. Qhov kev hloov pauv no ncaj qha txo qhov ntim ntawm ferroalloys xav tau ib tuj ntawm cov hlau.
2. Exothermic Energy Recovery: Txo kev siv hluav taws xob
Ib qho ntawm feem ntau saib tsis tau tus nqi -txuag nta ntawm covSIB Structureyog nws cov exothermic xwm thaum oxidation.
Thermal Boost hauv EAF
Cov oxidation ntawm Silicon Carbide yog cov tshuaj tiv thaiv exothermic heev. Rau txhua kilogram ntawm SiC oxidized, ib qho tseem ceeb ntawm thermal zog yog tso rau hauv lub yaj.
Kev txuag hluav taws xob: Siv SiC 88 ua deoxidizer tuaj yeem pab tswj lossis txawm tias qhov kub ntawm lub pas dej molten.
Hluav taws xob txo: Hauv Cov Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob (EAF) kev ua haujlwm, cov hluav taws xob hluav taws xob no hloov mus rau hauv qhov txo qis kilowatt- teev (kWh) noj ib lub tshav kub.
Los ntawm kev ntxiv cov hluav taws xob hluav taws xob nrog cov tshuaj siv hluav taws xob los ntawm SiC 88, mills tuaj yeem ua kom luv kais - mus rau - kais lub sij hawm thiab txo lawv cov nqi hluav taws xob tag nrho - qhov txiaj ntsig tseem ceeb tau muab cov nqi hluav taws xob nce rau lub Peb Hlis 2026.
3. Dual-Functioning: Alloying thiab Recarburization
Hauv ntau qib steel, silicon thiab carbon yuav tsum tau ntxiv kom ncav cuag lub hom phiaj specification.
- FeSi 75 txwv: Tsuas yog muab silicon; ib qho recarburizer cais (xws li GPC lossis Anthracite) yuav tsum tau yuav thiab ntxiv.
- SiC 88 Solution: Muab ob qho tib si silicon (~ 60% Si) thiab carbon (~ 25% C) ib txhij.
Los ntawm kev siv SiC 88, cov thawj coj kev yuav khoom tuaj yeem txo qhov nyuaj ntawm lawv cov saw hlau. Koj yeej tseem ceeb yuav ob alloys rau tus nqi ntawm ib. Qhov kev sib koom ua ke no txo cov nqi khaws cia, tuav haujlwm, thiab cov nqi logistical cuam tshuam nrog kev tswj hwm ntau cov khoom siv raw.
4. Slag Conditioning thiab hlau rov qab
Tsawg-purity SiC (qis dua 90%) yog ib qho tshwj xeeb slag txias txias.
- Slag Foaming: Cov pa roj carbon monoxide tsim tawm thaum SiC deoxidation txhawb nqa "ua npuas dej" hauv EAFs, uas tiv thaiv lub cub tawg refractory thiab txhim kho arc stability.
- Txhim kho tawm tswv yim: Zoo dua slag deoxidation tiv thaiv kev poob ntawm cov khoom muaj txiaj ntsig zoo (xws li Manganese lossis Chromium) rau hauv cov slag. Los ntawm kev khaws cov ntsiab lus no hauv cov hlau, SiC 88 ua kom muaj txiaj ntsig zoo dua metallurgical, txo tus nqi ntawm cov khoom siv tau zoo.
5. Kev pom kev lag luam: Kev taw qhia tus nqi Silicon Carbide
Raws li lub Peb Hlis 2026, lubSilicon Carbide nqirau cov qib metallurgical tseem nyob ruaj khov thiab kev sib tw siab tshaj -purity Ferrovanadium lossis tshwj xeeb FeSi.
| Qhov xwm txheej | Ferrosilicon 75 | Silicon Carbide 88 | Tus nqi cuam tshuam |
| Tus nqi | Siab | Nruab nrab -Low | Tsawg pib nqis peev. |
| Zog cuam tshuam | Nruab nrab / txias | Exothermic (kub) | Txo cov nqi hluav taws xob. |
| Muaj nuj nqi | Si xwb | Si + C + Deoxidizer | Hloov ob yam khoom. |
| Hlau Yield | Txuj | Txhim kho | Txo cov khib nyiab ntawm cov khoom kim kim. |
6. Kev xaus: Lub tswv yim hloov mus rau SiC 88
Rau lub zeb zeb uas tsim tau 1 lab tons ib xyoos ib zaug, txawm tias 5% txo qis hauv deoxidation thiab alloying cov nqi tuaj yeem ua rau ntau lab daus las hauv kev txuag nyiaj.Silicon Carbide 88tsis yog "kev hloov pheej yig" xwb; nws yog ib qho cuab yeej zoo tshaj plaws metallurgical uas optimizes lub zog, chemistry, thiab tawm los.
Xaiv SiC 88 tso cai rau koj qhov chaw los tiv thaiv qhov tsis sib haum xeeb ntawm kev ua lag luam ferroalloy thaum txhim kho cov khoom siv ntawm cov khoom kawg.
