Xi'an Huachan moollurgical Technical Technology Co {}}, ltf} Yog cov khoom siv hluav taws xob, xws li cov khoom siv hluav taws xob ua haujlwm, xws li kev siv hluav taws xob ntawm hluav taws xob (LF) Cov tshuab hluav taws xob, thiab submerged arc rauv (kev nyab xeeb).
Cov lus nug niaj hnub no yog tias cov hluav taws kub ua hluav taws xob sib txawv ntawm cov txheej txheem sib txawv ntawm cov txheej txheem kev sib txawv ntawm cov txheej txheem.
Tsis zoo li tsis tu ncua rauv tawg, feem ntau EAF ua haujlwm rau kev ua haujlwm EAF, thiab tshawb txog cov txheej txheem txuas ntxiv uas tau txhim kho lub tshuab hluav taws xob .
Yuav ua li cas hluav taws xob arc rauv hluav taws xob feem ntau ua haujlwm: batch ua
Tus Qauv EAF Ntau Lawm
EAF Steel UaUa raws li rov ua raws qib:
- Them (3-8 feeb)
SEEM / DRI tau thauj khoom rau hauv qhov cub cua sov
- Melting (40-60 feeb)
Hluav Taws Xob Arc Los Ntawm Cov Khoom Ntawm 1, 600-1, 800 Qib
- Refining (20-40 feeb)
Chemistry kev hloov kho, de-slagging
- Tapping (5-10 feeb)
Molten Steel tau nchuav tawm
Rauv Turaround (10-20} feeb)
Cov tshuaj kuaj, electrode kev hloov kho
Tag nrho cov voj voog lub sijhawm: 90-150} feeb
Raug cov cua sov txhua hnub: 12-18} batches
Vim li cas pob cov hom sib tw dominates EAF kev ua haujlwm
- Txwv cov khoom txwv: txhua tus nqi yuav tsum muaj cov ntawv tshiab / dri
- Zog txuag hluav taws xob: zoo arc stability nrog kev tsub nqi
- Kev Kho Kom Ua Kom Zoo: Kev tswj Chemistry xav tau cov theem sib tshooj
- Khoom Siv Khoom Siv: electrode thiab ru tsev kom xav tau downtime
Muaj kev zam: thawb mus rau kev ua haujlwm tas mus li
1.} Twin plhaub EAF Tsim
Pioneered los ntawm cov tuam txhab zoo li cov tuam txhab ua haujlwm zoo li Danieli thiab FMS pawg, Twin plhaub rauv lwm txoj ntawm ob lub nkoj:
Thaum ib lub plhaub melts, lwm tus kais / tsub
Qhov tshwm sim: nyob ze ntawm kev siv hluav taws xob txuas ntxiv (txog li 90% vs. 60% rau ib-plhaub)
2. acteeL constောင် ® constောင် ills (txuas ntxiv them)
Tsim los ntawm Tenova, cov kab ke no nta:
Nruam Scrap Conveyor Pub
Preheard scrap nrog off-roj (600-800 degree)
Cov txiaj ntsig:
15-20% txuag txuag
Txo Power Power hloov
30% siv sijhawm refractory ntev dua
3. hybrid EAF-LF Nruam Nruam Cov Tshuab
Qee cov mini-mills muab:
EAF rau thawj melting
Looj tes rauv taws (LF) rau kev kho kom tsis tu ncua
Nruam casting tsis muaj kev cuam tshuam
Cov Ntsiab Lus Tseem Ceeb cuam tshuam rau EAF kev ua haujlwm txuas ntxiv
| Yam tseem ceeb | Cuam tshuam rau txuas ntxiv | Txoj kev ua kom tau zoo |
|---|---|---|
| Seem Mov | Yuav tsum them yuav tsum tau | Seteel Tshuab, Scrap Yard Automation |
| Kev pab fais fab | Hloov pauv kev cuam tshuam kev cuam tshuam arcs | Cov pob zeb ntse sib xyaw, capactratoritor txhab nyiaj |
| Refractier hnav | Yuav tsum tau kaw rau relining | Advanced Monolithic Linings (MgGO-C) |
| Kev noj electrode | Xav tau kev hloov kho lub sijhawm | Nws Pib-Haum Cov Tshuab, Ultra-High-High Fais Electrodes |
| Ib puag ncig tswj | Cov kev txwv ntawm cov roj ntsha | Plaub-lub tshuab tshuab, ncej-sib txuas |
Kev Tshaj Tawm Kev Tshaj Tawm: EAF VS . Lub cev tawg ua haujlwm
| Chaw ua uas tsis tau haus | Fais arc rauv | Moj tej tawg ua kom sov |
|---|---|---|
| Kev Lag Luam Hom | Batch (feem ntau) | Nruam (5-15} Prisc Prists) |
| Raug rau kev puas tsuaj | 30-60 mins ntawm cov cua sov | <5% downtime/year |
| Yooj yooj | Tuaj yeem nres / pib txhua hnub | Lub hlis rov pib dua tom qab kaw |
| Zog Efficiency | 350-500 kwh / tuj | {{018-22 gj / tuj (thee khom) |
| Zoo tshaj plaws rau | Seem-nplua nuj thaj chaw, cov hlau tshwj xeeb | Cov Mills Loj Ntau Lawm |
Lub neej yav tom ntej: mus rau ntau txoj haujlwm EAF
1. Digitalization & Automation
-
Ai-powered twv ua ntej txij nkawm kev txo qis tsis tau npaj tseg

Batch niaj hnub no, ntxiv mus ntxiv tag kis
Thaum sawv ntxov eaFs ua lag luam hauv batch cycloies yog thawb tus ciam mus rau ib thaj chaw ua haujlwm ib nrab. kev lag luam yog nce zuj zus:
✔ Ob ntxaib-plhaub tsim tawm maximizing rauv kev siv
✔ Txuas ntxiv lub cuab yeej txuas ntxiv xws li consteel®
✔ Advanced Adven tswj kev nthuav dav inter-tshav kub qeeb
Rau cov stathermakers muaj kev xav txog EAF kev teeb tsa, to taub cov qauv ua haujlwm no yog qhov tseem ceeb rau:
- Kev Npaj Vaj Peev Xwm (Tseeb Ntau Lawm VS . theoretical)
- Zog Ua Haujlwm (Xav Tau Kev Tswj Xyuas Tus Nqi)
- Kev Txij Nkawm Kev Teem Caij (Nrov VS .}} period period)
Lub EAF ntawm lub neej yav tom ntej yuav tsis phim lub moj tej tawg sov rauv kev sib txuas ua ke, tab sis cov sib txawv yog nqaim los ntawm engineering innine .
