Oriented Hluav Taws Xob Hlau Txhawb Kev Txhim Kho Zoo Tshaj Plaws ntawm Kev Lag Luam Hluav Taws Xob

GNEE Steel CRGO Silicon hlau

Nrog rau kev txuag hluav taws xob, txo cov pa roj carbon emissions thiab lwm yam kev tiv thaiv ib puag ncig cov ntsiab lus nrov zuj zus, kev lag luam hauv qab ntawm cov khoom siv qis carbon steel hlau yuav tsum tau siab dua thiab siab dua, kev ua haujlwm siab ntawm silicon steel yog ib qho tseem ceeb ntawm cov khoom siv hlau nplaum hauv kev lag luam fais fab. , hluav taws xob engineering, hluav taws xob khoom siv thiab lwm yam lag luam ntawm kev tshawb fawb thiab kev loj hlob ntawm cov hlau nplaum sib nqus, cov hlau no tau siv dav hauv kev lag luam hluav taws xob, kev ntsuas ntsuas qhov ntsuas tsis siv neeg, Nws yog cov khoom siv tseem ceeb hauv kev lag luam hauv teb chaws.

Nws yog to taub hais tias oriented silicon steel yog cov khoom tseem ceeb ntawm lub transformer core, uas yuav ua tau ib tug muaj zog magnetic teb nyob rau hauv ib tug tej yam excitation magnetomotive quab yuam thiab yog lub sib nqus Circuit Court ntawm lub transformer. Cov qib siab taw qhia silicon steel muaj cov yam ntxwv ntawm kev sib nqus sib nqus thiab tsis tshua muaj hlau. Lub peev xwm ib-theem ntawm UHV transformer yog 3-4 zaus ntawm cov pa 500kV ib-theem transformer, thiab nws yog ib qho nyuaj rau tswj cov hlau nplaum to thiab tiv thaiv lub zos overheating, thiab cov rheology ntawm UHV transformer kuj cuam tshuam los ntawm harmonic, DC magnetic bias thiab lwm yam, yog li cov hlau tseem ceeb ntawm UHV thiab lub zog txuag transformer yuav tsum tau ua los ntawm qib siab silicon steel. Nws yog tsim nyog sau cia tias ua ntej xyoo 2009, Tuam Tshoj tsis tau paub txog cov thev naus laus zis tseem ceeb cuam tshuam nrog kev taw qhia silicon steel. Txhawm rau kom paub txog kev tiv thaiv kev ywj pheej ntawm Tuam Tshoj cov khoom siv hluav taws xob tseem ceeb thiab tsis txhob raug tswj hwm los ntawm lwm tus, Tuam Tshoj yuav suav nrog qib siab taw qhia silicon steel hauv "Made in China 2025 lub tswv yim" catalog, uas yog cov cuab yeej siv siab kawg thiab cov khoom lag luam tsom rau. txoj kev loj hlob ntawm cov khoom siv fais fab teb.

Tsis tas li ntawd, nrog rau kev nqis peev loj thiab kev loj hlob ntawm lub zog ntsuab xws li cua zog, photovoltaic, lub zog cia thiab lub zog tshiab lub tsheb them cov pawg thiab cov ntaub ntawv chaw, qhov kev thov rauoriented silicon hlautseem nce ntxiv. Nyob nruab nrab ntawm 2023 thiab 2030, tus nqi ntawm domestic oriented silicon steel yuav ncav cuag 2.5 lab tons rau 3 lab tons, nws xav tias qhov kev thov rau oriented silicon steel nyob rau hauv 2025 nyob rau hauv Tuam Tshoj yuav ncav cuag li 2.5 lab tons, thiab cov kev thov rau oriented silicon steel. Xyoo 2030 hauv Suav teb yuav ncav cuag li 3.2 lab tons.

Cold rolled grain oriented silicon steel

Ntxiv rau UHV thiab lub zog tshiab, qhov kev thov rau kev ua haujlwm siab ntawm silicon steel hauv lub cev muaj zog kuj tseem loj, thiab nws lub zog txuag thiab txo cov peev txheej carbon kuj tseem loj heev. Cao Haidong, tus lwm thawj saib xyuas ntawm lub teb chaws me me thiab nruab nrab lub cev muaj zog thiab System Engineering Technology Research Center, ntseeg hais tias qhov kev koom tes ntawm kev txuag hluav taws xob thiab kev ua haujlwm zoo rau kev txhawb nqa cov pa roj carbon ntau hauv Suav teb yog ze rau 70%. Yog li ntawd, kev txhim kho thiab siv cov khoom siv hluav taws xob ntsuab thiab muaj txiaj ntsig zoo yog tus yuam sij rau kev txuag hluav taws xob thiab txo cov pa roj carbon. Lub cev muaj zog carbon txo ntim yog loj. Tuam Tshoj tus uas twb muaj lawm lub cev muaj zog tuav ntawm txog 3.14 billion kilowatts, txhua xyoo kev siv hluav taws xob suav txog li 60% ntawm tag nrho cov zej zog kev siv hluav taws xob, kev siv hluav taws xob siv hluav taws xob ntawm 75%. Hauv 2021, lub teb chaws muaj hluav taws xob siv hluav taws xob yog 5,509 billion KWH, nrog rau kev faib ua feem ntawm thermal zog 68.8%, carbon dioxide emissions ib chav tsev ntawm hluav taws xob 577 grams / KWH xam, tag nrho cov pa roj carbon dioxide emissions ntawm lub teb chaws lub cev muaj zog yog hais txog 2.38 billion tons, ze rau tag nrho cov pa roj carbon dioxide emissions ntawm tag nrho cov zej zog 1/4. Nws yog txoj kev ceev tshaj plaws los txo cov pa roj carbon nrog kev nqis peev tsawg tshaj plaws. Piv nrog rau lwm cov kev daws teeb meem tshiab, txo qis tib yam ntawm cov pa roj carbon dioxide, lub cev muaj zog txuag kev nqis peev tsawg dua, thiab tsis muaj qhov chaw ntxiv thiab cov khoom siv ntxiv; Piv nrog rau lwm yam khoom siv hluav taws xob xws li boilers thiab diesel xyaw, tus nqi ntawm lub cev muaj zog yog qis dua, thiab kev hloov pauv hloov tau yooj yim dua thiab yooj yim dua.

Nws tau nkag siab tias thaum Lub Ob Hlis 2023, European Parliament tau dhau los ntawm EU's Carbon ciam teb hloov kho mechanism (CBAM), tseem hu ua carbonborder se lossis carbon tariff (carbonborder tax), uas yog cov se se los ntawm EU ntawm cov pa roj carbon emissions ntawm qee cov khoom xa tuaj. khoom. Raws li cov lus pom zoo ntawm EU Carbon Ciam Teb Tswjhwm mechanism, cov pa roj carbon ciam teb txoj cai mechanism yuav npog tsib sectors nyob rau hauv cov European carbon lag luam: hluav taws xob, hlau, cement, txhuas thiab chiv. Nyob rau tib lub sijhawm, kev lag luam steel, raws li cov peev txheej thiab lub zog siv kev lag luam, yog ib qho ntawm kev sib ntaus sib tua tseem ceeb hauv Suav teb kom ua tiav cov pa roj carbon nruab nrab. Cov txheej txheem ntawm kev ua tiav lub hom phiaj ntawm cov pa roj carbon nruab nrab yog cov txheej txheem ntawm kev txhim kho cov thev naus laus zis tshiab muaj peev xwm ntawm kev lag luam steel, cov txheej txheem ntawm kev txhim kho cov kev sib tw dav dav, thiab cov txheej txheem ntawm kev paub txog lub teb chaws steel los ua lub teb chaws muaj zog.
