Puas yog hluav taws xob arc ua kom muaj hluav taws xob ntau ntau?
Cov lus teb luv yogtau-Ane -afs yog lub tshuab ua hluav taws xob-ua kom muaj zog} Txawm li cas los xij, qhov kev txhim kho muaj ntau dua, thiab niaj hnub ua kom zoo dua li cas ua rau lawv muaj txiaj ntsig tshiab {{4 4}}
Cov hluav taws xob muaj hluav taws xob ntau npaum li cas?
Ib nrab arc rauv taws yuav tsum tau350 rau 500 kWh (kilowatt-teev) ntawm hluav taws xob ib tuj ntawm cov kua hlau ua.} rau kev xav:
Ib tug neeg raug u {. s} s.} tsev neeg siv txog30 kWh ib hnub.
Kev tsimib tuj ntawm cov hlauhauv ib eaf yuav ua rau muaj zog tib lub tsev rau12 mus rau 17 hnub.
Txawm li cas los xij, lub zog siv sib txawv raws li:
Qhov Loj Loj(Loj EAFs zoo li yuav ua tau zoo dua)
Cov Khoom Siv Raw(Siv cov hlau txo cov hlau (Dri) lossis cov ntawv hlau cuam tshuam rau lub zog xav tau)
Txheej txheem optimization(preheating seem, oxygen txhaj tshuaj, thiab hluav taws xob kev tswj hwm kev noj haus xwb)
Kev rhuav tshem lub zog siv hauv EAF
Melting cov seem (60-70}% ntawm tag nrho lub zog)- Lub zog hluav taws xob tseem ceeb los ntawm cov hluav taws xob hluav taws xob, uas tau mus txog qhov kub3, {000℃(5,432 Qib F)kom yaj cov hlau .
Refining & Kev Txij Nkawm Kub (20-30%)- tom qab melting, ntxiv lub zog xav tau rau kev ua yeeb yam tshuaj lom neeg (e {{}} g}!
AUXILIARIARIARIAL TSHUAB (10-20%)- Qhov no suav nrog cov tshuab txias txias, tso pa tawm, thiab electrode tswj .
Piv piv EAFs los ua kom tawg
ThaumEAF Steel Uayog hluav taws xob-hnyav, lawv feem ntauNtau lub zog-txuag tag nrhotshaj li cov kev ua kom tawg ua kom tawg (BFS):
| Yam tseem ceeb | Fais arc rauv (EAF) | Moj Tej Siab Sov (Bf) |
|---|---|---|
| Thawj lub zog | Hluav Taws Xob (Los Ntawm Daim Phiaj / Txuas Ntxiv) | Coke (Coal-based) |
| Kev Siv Zog | 350-500 kwh / tuj | {{020-25 gj / tuj (≈ 5,500-7}} kwh / tuj) |
| CO₂ Emissions | Qis dua (yog muaj hwj chim los ntawm lub zog huv) | Siab dua (vim coke usents) |
| Yooj yooj | Tuaj yeem pib / nres sai sai | Yuav tsum tau ua haujlwm txuas ntxiv |
Tseem ceeb takaway:Thaum EAFs Siv Hluav Taws Xob tseem ceeb, lawv zam dhau cov pa roj carbon loj, tshwj xeeb tshaj yog thaum muaj zog hluav taws xob, tshwj xeeb thaum muaj zog txuas ntxiv rau lub zog {}}
Yuav ua li cas tam sim no EAF siv hluav taws xob tau siv hluav taws xob
Cov thev naus laus zis tshiab yog ua EAFS ntau dua:
1. Seem preheated
Qee lub tshuab (zoo liConceleel ® lossis co co rauv) Preheat cov khoom siv khib nyiab los ntawm kev ua pa tawm, txiav zog siv los ntawm15-20%.
2. Oxygen & Roj Txhaj
Txhaj tshuajpalossis cov roj pab roj cua sov cua sov, txo lub sijhawm thiab lub zog xav tau {}}
3. Ntse Fais Fab Tswj
Tau siab kawgCov Ntawv Teev Cov Tshuab Hluav Taws XobTxhim kho Ac stability, tsawg zog khib nyiab .
4. Txuas Ntxiv Hluav Taws Xob
Qee tus steelmakers tam sim no siv hnub ci, cua, lossis hydroelectric rabe khiav EAFs, txo qis lawv cov hneev taw carbon {}}
Lub neej yav tom ntej: tuaj yeem muaj EAF puas ua tau ntau dua?
Nrog nce hluav taws xob cov nqi hluav taws xob thiab cov kev cai ib puag ncig ib puag ncig, kev lag luam yog thawb rau:
Hybrid EAF(ua ke ua ke lub zog txuas ntxiv nrog hydrogen-based txo)
Ai-tsav tsim kho tshiab(Kev tswj hwm lub zog)
Ultra-siab-hwj chim (UHP) Furnaces(nrawm melting=tsawg zog poob)
Yog, hluav taws xob arc ua tau ntau cov hluav taws xob - tab sis lawv tseem muaj qhov ua kom muaj txiaj ntsig zoo thiab kev ua haujlwm tseem ceeb hauv ntsuab steel ntau lawm.
