Dab tsi yog Green Production Technologies rau EAF Short Process Steelmaking?

Raws li keeb kwm yav dhau los ntawm "ob chav carbon" lub hom phiaj, tshawb nrhiav kev txhim kho thiab kev siv cov thev naus laus zis thiab cov txheej txheem yog qhov tseem ceeb ntawm kev txhim kho steel kev lag luam yav tom ntej.

Tam sim no, Tuam Tshoj tus crude steel ntau lawm yog blast furnace converter steelmaking. Cov txheej txheem no suav nrog tag nrho cov txheej txheem los ntawm kev ua cov khoom siv raw mus rau kev ua hlau thiab steelmaking, yog li nws muaj kev siv zog siab thiab siv carbon emission siv. Ntawm lawv, thee yog cov roj tseem ceeb ntawm cov txheej txheem thiab lub ntsiab ntawm CO2 emissions.

Hauv qhov sib piv, cov txheej txheem luv luv steelmaking txheej txheem ntawm hluav taws xob arc rauv siv cov khoom siv rov ua dua tshiab los ua cov khoom siv tseem ceeb, hluav taws xob raws li lub zog nruab nrab, thiab siv cov nyhuv arc thermal los yaj cov seem hlau rau hauv cov hlau molten, paub tias "hloov cov thee nrog hluav taws xob. ", uas muaj cov txiaj ntsig zoo carbon txo. "Nyob zero carbon emission" hluav taws xob arc rauv steelmaking siv ntsuab thiab huv zog rau smelt tsawg carbon los yog micro carbon raw thiab auxiliary cov ntaub ntawv, thiab ua steel billets los ntawm "tsis carbon related" smelting technology, thiaj li mus cuag zero CO2 emission nyob rau hauv lub steelmaking txheej txheem.

Dab tsi yog qhov luv txaus steelmaking txheej txheem ntawm hluav taws xob arc rauv?

Hluav taws xob arc rauv steelmaking yog steelmaking txoj kev uas siv cov nyhuv tshav kub ntawm hluav taws xob arc rau cua sov rauv nqi rau smelting. Lub zog hluav taws xob yog nkag mus rau hauv hluav taws xob arc steelmaking rauv los ntawm graphite electrode, thiab cov arc nruab nrab ntawm electrode kawg thiab lub cub tawg yog siv los ua qhov cua sov rau steelmaking.

Cov hlau nplaum yog cov khoom siv tseem ceeb rau hluav taws xob arc rauv steelmaking, thiab alloy, txiv qaub, carburetor, thiab lwm yam yog cov khoom siv raw. Cov txheej txheem tseem ceeb ntawm hluav taws xob arc rauv steelmaking muaj xws li slag raking, them, fais fab kis, melting, oxidation, txo refining thiab tapping.

Dab tsi yog cov khoom siv ntsuab ntawm hluav taws xob arc rauv?

Green zus tau tej cov hluav taws xob arc rauv yog tsuas yog los txo lub zog noj, txo cov pa phem emissions thiab txhim kho cov kev pab cuam rov qab efficiency. Txhawm rau kom paub txog kev tsim ntsuab ntawm hluav taws xob arc rauv, cov thev naus laus zis tseem ceeb xws li pov tseg cov cua sov rov qab, hloov coke thiab seem preheating tau tsim ua tiav.

Pov tseg tshav kub rov qab:Ib tug loj npaum li cas ntawm high-temperature plua plav flue roj yuav raug tsim thaum lub sij hawm smelting txheej txheem ntawm hluav taws xob arc rauv, uas yuav siv sij hawm txog 11 feem pua ​​ntawm tag nrho cov zog input ntawm lub hluav taws xob arc rauv, mus txog 20 feem pua. Kev siv hluav taws xob zoo hauv cov roj flue tuaj yeem txuag tau ntau lub zog, yog li txo qis CO2 emissions.

Coke hloov:Cov pa roj carbon monoxide yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua ntawm lub pas dej molten kub nce, nplawm thiab ua npuas ncauj slag submerged arc nyob rau hauv cov txheej txheem ntawm tsoos hluav taws xob arc rauv smelting. Nyob rau hauv ntsuab zus tau tej cov hluav taws xob arc rauv, kev noj ntawm cov pob txha tsis txuas ntxiv zog xws li coke yuav tsum tau txo kom ntau li ntau tau.

Qhwv preheating:seem yog preheated thiab ces muab tso rau hauv lub cub tawg, uas yuav txo tau lub smelting voj voog ntawm hluav taws xob arc rauv thiab txo lub zog noj. Nws yog ib qho tseem ceeb ntawm kev txuag hluav taws xob rau hluav taws xob arc rauv smelting.

Dab tsi yog txoj kev loj hlob ntawm domestic EAF luv luv txheej txheem steelmaking?

Nrog rau kev txhawb nqa ntawm "ob npaug carbon" lub hom phiaj, kev nce nrawm ntawm cov khoom seem thiab txo cov nqi seem, hluav taws xob arc rauv steelmaking yuav dhau los ua cov txheej txheem steelmaking tseem ceeb hauv Suav teb.

Nyob rau hauv lub neej yav tom ntej, hluav taws xob arc rauv steelmaking yuav ntxiv optimize tag nrho cov txheej txheem ntawm hluav taws xob arc rauv steelmaking raws li batching, fais fab mov, oxygen mov, auxiliary zog tswv yim, slagging thiab lwm yam txheej txheem, txhim kho cov hluav taws xob arc rauv steelmaking txheej txheem integrating kev lag luam, txheej txheem, zoo, tus nqi thiab kev tiv thaiv ib puag ncig, thaum kawg ua tiav lub hom phiaj ntawm ntsuab, ntse, ua tau zoo thiab tsis tshua muaj nqi steelmaking ntawm hluav taws xob arc rauv, thiab ntxiv txhawb kev hloov pauv thiab txhim kho kev lag luam steel.
