Hauv hluav taws xob arc rauv (EAF) steelmaking, tswj cov nqi tsim khoom yog qhov kev txhawj xeeb tseem ceeb rau cov nroj tsuag steel. Ntawm tag nrho cov nqi tsim nyog,kev siv hluav taws xob thiab kev sib txuas ntxivua lub luag haujlwm tseem ceeb.
Qhov kev tshawb fawb no piav qhia li casSilicon Carbide 88 (SiC 88)tuaj yeem txo tag nrho cov nqi steelmaking los ntawm:
- Muab cov cua sov ntxiv los ntawm cov tshuaj tiv thaiv exothermic
- Hloov ib feem ntawm cov tsoos alloys xws li ferrosilicon
- Txhim kho tag nrho cov txheej txheem efficiency
Vim li cas SiC 88 Ua Haujlwm hauv EAF Steelmaking
Silicon carbide koom nrog hauv cov tshuaj tiv thaiv metallurgical hauv qhov cub:
SiC + O₂ → SiO₂ + CO + Kub
Cov tshuaj tiv thaiv no tso tawm cua sov thaum lub sij hawm steelmaking txheej txheem, uas pab:
- Txo kev siv hluav taws xob
- Ceev melting
- Txhim kho thermal efficiency
Tib lub sijhawm, SiC muab ob qho tib sisilicon (Si)thiabcarbon (C), ib nrab hloov lwm yam additives.
Kev Kawm Sib Piv: 50-Ton EAF
Cov xwm txheej ntau lawm

Tus nqi hluav taws xob:$0.10/kWh
Tus nqi:$50.00/ton
👉 Tag nrho cov nqi (qhov tseem ceeb): $63.00/ton
Tom qab Optimization (Siv SiC 88)
Hloov pauv:
Hloov ib feem ntawm FeSi nrog SiC 88
Siv SiC rau ob qho tib si silicon mov thiab cua sov tsim
| Yam khoom | Tus nqi |
|---|---|
| Kev siv SiC88 | 8 kg / ton steel |
| SiC88 nqi | $900/ton |
| Nqi ib ton steel | $7.20 |
Txo kev siv FeSi:
FeSi tshiab: 4 kg/ton
Nqe: $5.20
👉 Tag nrho cov nqi: $ 12.40 → $ 12.40
Hluav taws xob txo
Vim yog exothermic cov tshuaj tiv thaiv ntawm SiC:
Kev txuag hluav taws xob:20 kWh/ton
Kev txuag nqi:
👉 20 × $0.10 = $2.00/ton
Tag nrho cov nqi sib piv
| Yam khoom | Ua ntej (FeSi) | Tom qab (SiC 88) |
|---|---|---|
| Alloy nqi | $13.00 | $12.40 |
| Tus nqi hluav taws xob | $50.00 | $48.00 |
| Tus nqi tag nrho | $63.00 | $60.40 |
Txuag zaum kawg
👉 Txuag ib tuj steel: $2.60
Rau qhov cub 50-tuj:
👉 Tag nrho txuag ib qho cua sov: $ 130
Rau kev tsim khoom txhua hli (piv txwv: 10,000 tons):
👉 Kev txuag txhua hli: $ 26,000
Cov txiaj ntsig tseem ceeb ntawm Kev Siv SiC 88
1. Kev siv hluav taws xob qis dua
Exothermic tshuaj tiv thaiv txo hwj chim xav tau hauv EAF.
2. Txo cov nqi alloy
Ib nrab hloov ferrosilicon thiab carbon additives.
3. Txhim kho cov txheej txheem ua tau zoo
Cov melting sai dua thiab zoo dua thermal tshuav nyiaj li cas.
4. Kev tswj tus nqi zoo dua
Ntau kwv yees thiab ruaj khov tus nqi tsim khoom.
Thaum twg Koj Yuav Tsum Siv SiC 88?
SiC 88 yog qhov tsim nyog tshwj xeeb thaum:
- Tus nqi hluav taws xob yog siab
- Ntau lawm nplai yog loj
- Kev tswj tus nqi ruaj khov yog xav tau
- Kev hloov ib nrab ntawm FeSi tau txais
Kev suav cov qauv (Rau koj tus kheej cog)
Koj tuaj yeem kwv yees kev txuag nyiaj siv cov qauv no:
Txuag ib tuj=(FeSi txo × FeSi tus nqi sib txawv) + (Kev txuag hluav taws xob × nqi hluav taws xob) - SiC nqi
Piv txwv:
- Kev txuag hluav taws xob=20 kWh
- Tus nqi hluav taws xob=$0.10
- SiC vs FeSi tus nqi sib txawv suav nrog
👉 Qhov tshwm sim ≈$2-3 ib tuj
