Niaj hnub no cov kev lag luam steel kev lag luam niaj hnub no, ua kom muaj zog steel tau zoo yog qhov chaw ua kom zoo nkauj
Ntawm Xi'an Hucang, peb ua tshwj xeeb hauv kev tsim khoom LURC cov tshuab hluav taws xob ua ke (EAF), VD) {} Daim ntawv qhia no yuav piav qhia:
Dab tsi ib lrf yog thiab nws ua haujlwm li cas
Cov txiaj ntsig tseem ceeb dua cov kev txhim kho cov hau kev
Nws yuav txhim kho cov hlau zoo rau cov ntawv thov tseem ceeb
Cov qeb thev naus laus zis tshiab
Txog thaum kawg, koj yuav nkag siab vim li cas ua steelmakers cia rau lrf Technology-thiab li cas nws tuaj yeem ua kom zoo dua koj cov khoom lag luam.
LRF Cov Hauv paus: Cov ntsiab lus & Cov Tub Ntxhais Kawm
Dab tsi yog LRF?
A Tshob Refining Rauv(LRF) yog chav tsev me me ntawm cov hlau uas ua kom pom tseeb ntawm kev ua kom zoo nkauj (hauv EAF lossis lub tshuab hluav taws xob tawg)} Nws cov haujlwm tseem ceeb muaj:
Decarburization - kho cov ntsiab lus carbon concisely .
Desulfurization - tshem tawm leej faj los tiv thaiv brittlession .
Alloying - ntxiv chromium, npib tsib xee, thiab lwm yam .}, rau cov hlau nplaum / Alloy}
Kev tswj qhov kub thiab txias - ua kom pom kev zoo pouring mob .
Nws yuav ua haujlwm li cas (kauj ruam-ib-kauj ruam)
Hloov: Molten Steel tau Tapped los ntawm EAF rau hauv lub tsev .
Cua Sov: Electrodes Rechate Hlau (kom them rau qhov kub thiab txias tso) .
Refining: Txhaj tshuaj Argon roj Stors Steel Steel thaum alirots / chemical yog ntxiv .
Kev kuaj: Kev kuaj xyuas cov kws tshuaj ntsuam xyuas thiab kho kom txog thaum cov lus tau ntsib .
Casting: lub ntsej muag ua kom zoo nkauj yog xa mus txuas ntxiv ua ke lossis ingot pwm .
Qhov Tseem Ceeb: Lrfs tso cai "tsuas yog-hauv-lub sijhawm" kev hloov kho, txo tus nqi ntawm hom hlau .
Vim li cas Statmakers siv LRFS: 5 cov txiaj ntsig tseem ceeb
Piv rau kev vam khom rau ib leeg ntawm cov thawj rhaub dej kub (zoo li EAFs), lrfs xa:
. kev tswj tau sib xyaw
Ua tiav PPM-theem precision rau cov sulfur, oxygen, thiab alloys .
Tseem ceeb rau API cov kav dej, cov hlau Aerospace, thiab tsheb qib tsheb .
B .} Txhim kho kev huv si (tsawg dua inclusions)
Argon stirring tshem tawm cov tsis tau xim hlau .
Cov txiaj ntsig hauv kev nkees nkees ua-loj heev rau bearings thiab zog rau .
C . lub zog & cov nqi txuag
EAFs tuaj yeem tsom mus rau melting (mus voj voog (sai dua), thaum LRF cov leeg ua kom tsis txhob .
Txo cov khoom noj ua hauj lwm thiab cov qhab nias mus txog 30% (qhov chaw:Tus ISSF, 2023).
D .} yooj yim nyob rau hauv ntau lawm
Ib LRF tuaj yeem pab ntau EAF, ua kom tau cov khw pem teb logistics .
Pab kom cov khoom me me ntawm cov neeg tshwj xeeb uas tsis muaj hluav taws xob downtime .
E . zoo dua qhov kub
Tiv thaivtxiasThaum lub sij hawm ua, txo qhov tsis xws luag zoo li cov kab nrib pleb .
Lrf vs .}} lwm cov txheej txheem theem nrab
Thaum Lrfs tus kav, xaiv tau - txhua tus nrog Pros / Cons:
| Txojkev | Zoo tshaj plaws rau | Kev txwv |
|---|---|---|
| Txhais | High-alloy steels, kaw thev taus | Siab dua capex tshaj li qhov yooj yim ladle cub |
| VD / vod | Hydrogen-rhiab hlaus (e . g., nuclele) | Lub sijhawm qeeb qeeb |
| CAS-OB | Kev kho cov pa roj carbon sai | Tsawg Tsawg Desulfurization Muaj Peev Xwm |
Txoj cai ntawm tus ntiv tes xoo: LRFs yog "Swiss Army riam" rau kev kho kom haum dua tshiab, thaum VD / vod txhais ultra-tsawg roj .
Kev nrhav hauv LRF thev naus laus zis
Niaj hnub tam sim no LRFS tam sim no tseem ceeb:
Ai-powered Control Txheej Txheem: kwv yees kev ua tau zoo ib qho ntxiv siv cov sense-sensors {2}
Eco-Argon Stirring: txo cov roj kev noj haus los ntawm 20% (JFE Hlau, 2024).
Modular tsim: Kev teeb tsa ceev dua / hloov kho (peb [koj lub tuam txhab qauv] nta no) .
Cov ntawv thov tiag tiag: qhov twg lrfs ci
Kev Kawm Kev Kawm: Stainless Hlau Ntau Lawm
Txiav sulfur los ntawm 0 {. 020% rau 0.002% (sib tham ittm A480).
Txo cov npib tsib xee pov tseg los ntawm 15% ntawm meej alloy rov piv.
Niche siv
Cuab Steel Hlau: Tswj Vanadium / Cov pa roj carbon piv rau hardness .
Hluav taws xob hlau: lowers leej faj los txhim kho cov khoom sib nqus muaj zog .
Puas yog LRF txoj cai rau koj cov nroj tsuag?
LRFS tsis muaj kev xaiv rau mills hom phiaj:
✔ Muaj qeb tshiab siab
✔ Cov nqi ua haujlwm qis dua
✔ Sustainability (tsawg dua rework=be}?)
