Xi'an Huachang Metallurgical Technical Technical Technical Technology Co., Lag Luam ARC REACKS (LRF) Cov tshuab hluav taws xob, thiab submerged arc rauv (kev nyab xeeb).
Hauv kev lag luam steelmaking, kev xaiv ntawm cov kev siv hluav taws xob ua haujlwm ntau ntxiv, ib puag ncig ntawm cov neeg siv khoom ntawm cov qauv steel: tusFais Arc Rauv (EAF Steel Ua). tsis zoo li cov khoom siv hluav taws xob ib txwm muaj rau cov hlau ua kom sib xyaw ua ke, siv lub pob zeb ua kom zoo nkauj
Cov ntawv no tshawb nrhiav vim li cas EAF yog kev daws teeb meem rau cov steelmaking rau cov hlau loj {2 Peb tseem yuav sib tham txog cov tshuab hluav taws xob thaum xaiv hluav taws xob tshuab {}}
Lub Hluav Taws Xob Arc Rauv (EAF): Cov Seem Hlau Hlau
Yuav siv EAFs siv cov scrap hlau
Fais Arc rauv taws yog tsim los rau melt seem steel siv cov hlau roj hluav taws xob nrog cov hlau uas muaj hluav taws xob tsis sib xws
Cov Seem yog thauj khoom rau hauv lub cub hluav taws, qhov twg kub tshaj 1,600℃(2,912 Qib F) Melloing cov hlau {Melloy}
Qhov Zoo ntawm Scrap Raws Li EAF Steelmaking
Kev Siv Nyiaj Txiag & Kev Lag Luam
EAFs txo kev cia siab rau nkauj xwb hlau ore, txo qis kev cuam tshuam rau {}}
Recycling SCRAP hlau txiav los ntawm ~ 75% piv rau cov kev sib zog ua kom tawg (ntiaj teb hlau txuas).
Zog Efficiency
Tam sim no EAFs haus ~ {350-400 Kuv tsis muaj steel ntawm steelmaking .
Kev nrhav kev hloov pauv ntxiv txo qis dua kev siv hluav taws xob ntxiv siv hluav taws xob .
Yooj Yim & Ceev
EAF tuaj yeem pib thiab nres nrawm, yoog raws kev lag luam thov.
Kais-rau-kais lub sij hawm tuaj yeem muaj tsawg li30-40 feeb rau mini-mills.
Nqi zog-ua hauj lwm
Txo qis peev txheej tshaj li cov tshuab hluav taws kub tawg .
Cov nqe nqe ntawm cov nqe ntawm cov qauv ntau dua li cov hlau ore / coking thee .
Sib piv nrog lwm hom rauv taws
Thaum EAFs Dominate Scrap-based ntau lawm, lwm cov chaw ua kom sov tau khawb hauv cov peev xwm sib txawv:
{{0 {}}} cov pa roj oxygen (bof)
SCRAP siv: ~ {10-30% ntawm kev them nqi (feem ntau kub hlau los ntawm cov rhuab hluav taws) .
Txwv tsis pub dhau: tsis tuaj yeem khiav ntawm 100% seem vim tsis txaus ua cua sov tiam .
2. induction rauv
SCRAP siv: 100% tau, tab sis feem ntau rau cov batcher me me (e ., founderries).
Txwv tsis pub dhau: Qhov tsim nyog rau cov nplai loj steelmaking.
{{0 {{} Tshos Tshuaning Refaces (LRF)
Lub luag haujlwm: kho cov hlau los ntawm EAF / BOF; tsis yaj scrap ncaj qha.
Cov kev txiav txim siab tseem ceeb rau kev ua haujlwm raws seem
- Seem Zoo Tswj
Cov khoom paug (e {{{{{0} g ., tooj liab, tuaj yeem cuam tshuam cov khoom siv hlau.
Kev daws teeb meem: kev txheeb xyuas siab, Dri / hbi blending .
- Kev noj electrode
Graphite electrodes yog qhov nqi loj loj (~ $ 2,000}} {{{4 4}
Txhim kho Arc ruaj khov txo cov hnav .
- Kev Tswj Fwm
Cov pa hluav taws xob (plua plav, Nox) yuav tsum tau ntsib cov qauv hauv zos .
Ntau yam mills yuav muaj lub hnab ntim lim dej lim lim thiab carbon txhaj tshuaj tshuab.
Lub neej tom ntej ntawm seem hauv steelmaking
Nrog rau cov thoob ntiaj teb seem muaj nqis los ua kom loj hlob (OECD kev kwv yees 1 billions tons / xyoo los ntawm 2030), EACH} EQ tawm tshiab xws li:
Hybrid EAFs Integrogen Burers .
Ai-kev them nqi tsub ua kom zoo rau cov scrap ua kom zoo tshaj plaws .
Rau cov khoom lag luam hlau ua ntej cov qauv hluav taws xob, hluav taws xob ua haujlwm ntxiv, thiab cov peev txheej ib puag ncig txuas ntxiv, thiab cov kev txhawb nqa ib puag ncig hauv.
