Dab tsi yog qhov txawv ntawm bof thiab EAF steel ua

Cov txheej txheem statmaking feem ntau yog cov pa roj oxygen yooj yim (bof) thiabEAF Steel UaCov hau kev .

Cov pa roj oxygen yooj yim (bof), tseem hu ua Oxygen hloov pa, yog ib qho kev siv hlau, thiab feem ntau yog hais tias yog "Steel Steelmaking" txheej txheem .

1.} Cov ntaub ntawv sib tw: cov hlau sib tw yog cov hlau sib tsoo yog cov hlau me me

2.} e oxygen tshuab: oxygen reacts thiab txo cov pa roj carbon, tig cov hlau los tsim cov hlau.

3. txwv tsis pub ntxiv: Limestone ntxiv rau cov txiv qaub thiab phosphorus, uas sib txuas nrog cov txiv qaub los sib cais los ntawm cov hlau .

1. Cov txheej txheem bof yog qhov ua tau zoo hauv kev tsim cov hlau loj ntawm cov nplai steel ntawm cov steel nroj tsuag .

2. Cov kauj vab bof feem ntau muaj cov hlua roj carbon ntau dua li cov kev siv hluav taws xob ntau dua EAF txoj kev.

3. Lub bof yog qhov zoo rau cov hlau thiab tau siv dav hauv cov hlau uas muaj ntau, kev tsim kho, thiab vaj tse, thiab lwm qhov chaw.

TusEAF Steel Ua(Electric Arc rauv taws) yog ib qho kev kawm tshiab thiab ntau dua ib puag ncig {} Nws tseem tuaj yeem siv cov hlau txo ncaj qha (DRI) lossis lwm yam khoom siv ntawm cov hlau.

1. Lub ntsiab lus tseem ceeb rau EAF cov txheej txheem yog cov qauv hluav taws xob los kuj tseem tuaj yeem siv cov roj ntsha ntxiv .

{{02. hauv EAF, High-voltage hluav taws xob arcs yog qhov ua kom sov tuaj txog rau 3, {} degree, txaus .

3. Cov hlau Molten steel tsim tawm hauv Eas oxygen thiab lwm tus neeg sawv cev yuav raug ntxuav cov hlau thiab kho nws cov tshuaj sib xyaw ua ke.

{{01. EAsfs yog yoog raws li bofs nyob rau hauv cov nqe lus ntawm hom raw thiab txo qhov kev xav tau rau nkauj xwb hlau.

2.} Cov txheej txheem EAF yog suav tias yog cov hluav taws xob ntau dua li, nws tseem tuaj yeem siv hluav taws xob qis dua nyob ntawm seb

{{03. Thaum EAFs yog feem ntau siv rau kev tsim cov hlau zoo li cov hlau zoo li cov hlau zoo li cov hlau, thiab cov high-zog steel {}}

Bof: feem ntau siv cov hlau molten los ntawm cov tshuab hluav taws kub tawg thiab ib qho me me ntawm cov scrap hlau {}}}}}

EAF: feem ntau siv cov qauv steel, txawm hais tias Dri thiab npua siv hlau kuj tseem siv tau.

Bof: relies ntawm coke thiab co-derated khoom lag luam rau lub zog, ua rau muaj ib qho kev ntsuas dua tshiab ntxiv.

EAF: Siv hluav taws xob EAs, uas tuaj yeem tsim hluav taws xob, uas tuaj yeem tsim hluav taws xob ntxiv, ua rau ib qho kev cuam tshuam ib puag ncig ib puag ncig ib puag ncig {}}

Bof: cov pa roj carbon ntau dua vim kev siv Coke .

EAF: Ib puag ncig ib puag ncig ntau, tshwj xeeb yog siv hluav taws xob los ntawm kev siv hluav taws xob txuas ntxiv hluav taws xob .

Bof: zoo tshaj plaws haum rau kev ntsuas loj ntawm cov hlau, feem ntau siv hauv kev sib xyaw cov nroj tsuag steel nroj tsuag {}}

EAF: Feem ntau siv rau me dua, ntau dua cov batches ntawm cov hlau tab sis muaj qhov yooj los ua ntau yam khoom .

Bof: feem ntau yuav raug nqi ntau dua rau cov khoom loj tshaj vim kev lag luam ntawm cov nplai.

EAF: Feem ntau kim dua ib tev ntawm cov hlau, tab sis cov nqi tuaj yeem them nyiaj los ntawm kev siv seem ntawm seem thiab txo cov nqi siv tsis raug nqi {}}

BOF: Tsis muaj peev xwm hloov tau, raws li nws yuav tsum tau muaj cov hlau ruaj khov ntawm molten hlau los ntawm cov ntshiab rauv .

EAF: Ntau dua yooj yim, raws li nws tuaj yeem siv ntau cov ntaub ntawv tawm tswv yim, suav nrog cov steel hlau {}}}}

Xaiv ntawm bof thiabEAF Steel UaNyob ntawm cov nplai ntawm cov nplai thiab cov kev cai hlau tshwj xeeb:

{{01.} rau cov nplai loj, xws li cov qauv tsim khoom, xws li hauv kev tsim kho thiab cov hlua khi yog ntau dua li cov nqi-{5}}

2.} rau cov qauv me me, cov qauv EAF yog qhov kev txhawj xeeb ntawm ib puag ncig thiab lub zog hluav taws xob yog qhov tseem ceeb.
