Hluav taws xob hlau kev lag luam tsom xam: Qib, tso zis thiab xav tau

Yuav Ua Li Cas Hluav Taws Xob Hlau yog Classified

Hluav taws xob hlau, tseem hu ua silicon steel lossis lamination steel, yog cov khoom sib nqus mos siv los tsim cov cores rau transformers, motors, generators thiab lwm yam khoom siv hluav taws xob. Nws tau muab faib ua ob tsev neeg los ntawm cov txheej txheem tsim khoom: kub- dov hluav taws xob hlau thiab txias- dov hluav taws xob hlau.

Txias- cov ntawv dov muaj ntau cov tuab tuab, zoo dua qhov zoo thiab kev ua haujlwm sib nqus ntau dua li kub- cov ntawv dov, yog li txias- cov khoom dov tau hloov pauv kub- dov cov khoom hauv transformer thiab lub cev muaj zog. Hauv tsev neeg txias-khoov, cov khoom tau muab faib ntxiv los ntawm kev qhia hauv cov nplej hauv cov nplej- taw qhia (GO) thiab tsis yog- taw qhia (NGO) hluav taws xob hlau.

Grain-Oriented vs Non-Oriented Hluav Taws Xob Hlau

Grain-Oriented Hluav Taws Xob Hlau (GO)

GO steel muaj cov nplej raws li qhov tseem ceeb hauv ib qho kev taw qhia tom qab tshwj xeeb dov thiab annealing. Nws cov ntsiab lus silicon yog qhov siab, thiab nws cov khoom sib nqus yog zoo heev nyob rau hauv cov kev taw qhia dov. Nws yog siv tsuas yog rau transformer cores, qhov twg txoj kev flux ua raws li ib qho kev taw qhia. GO kev ua tau zoo raug txheeb xyuas los ntawm kev ntsuas sib nqus tom qab tsim khoom: yog tias qhov sib nqus induction ntawm 800 A / m qis dua li ntawm 1.88 T, qib yog cais raws li cov lus pom zoo -oriented steel (CGO); saum toj no 1.88 T, nws yog cais raws li high magnetic induction oriented steel (HiB).

Tsis yog -Oriented Electrical Steel (NGO)

NGO steel tau random faib nplej thiab qis cov ntsiab lus silicon. Nws cov khoom sib nqus yog ze li ntawm isotropic, uas haum rau rotating tshuab xws li motors thiab generators qhov twg flux kev taw qhia hloov tsis tu ncua. NGO cov qhab nia raug muab qhab nia feem ntau los ntawm kev poob ntawm 50 Hz thiab 1.5 T lossis 1.0 T, raws li kev faib tawm xws li GB / T 2521 thiab IEC 60404-8-4.

Performance Indicators thiab Qib Lub ntsiab lus

Qhov kev ua tau zoo ntawm GO steel yog txhais los ntawm cov ntsuas xws li hlau poob thiab sib nqus induction, thiab feem ntau yog qhov txawv ntawm qib qib. Qhov qis dua tus nqi poob thiab qhov siab dua qhov sib nqus induction, qhov kev ua tau zoo dua thiab qis dua lub zog transformer poob. Raws li tib lub peev xwm, cov tub ntxhais ua los ntawm qib siab dua -qib taw qhia steel muaj qhov ntim me me thiab qhov hnyav, txuag hluav taws xob steel ntawv, hlau nplaum hlau thiab cov ntaub ntawv rwb thaiv tsev.

Kev lag luam tso zis thiab qauv

Tuam Tshoj tau dhau los ua tus tsim khoom loj tshaj plaws hauv ntiaj teb thiab cov neeg siv khoom siv hluav taws xob hlau, tab sis qhov kev faib ua feem ntawm cov nplej - taw qhia hluav taws xob hlau nyob rau hauv tag nrho cov zis tseem txwv. Xyoo 2021, Tuam Tshoj cov khoom siv hluav taws xob tag nrho tau nce mus txog 13.1828 lab tonnes, ntawm 1.809 lab tonnes yog nplej - taw qhia thiab 11.3819 lab tonnes tsis yog - taw qhia hluav taws xob hlau. Qhov sib piv qhia txog qhov tseem ceeb ntawm kev tsim lub cev muaj zog, thaum transformer -qib GO steel txuas ntxiv loj hlob nrog kev nqis peev hauv phiaj xwm thiab kev txhim kho kev ua haujlwm.

Xav tau tsav tsheb thiab Market Outlook

Transformer efficiency cov cai thoob ntiaj teb tab tom thawb cov khoom siv los hloov cov cores qub nrog cov qib qis - poob HiB, nce tus nqi ntawm GO steel.

Lub zog tauj dua tshiab tsim- tawm, suav nrog cua thiab hnub ci, ntxiv cov tshuab hloov pauv thiab cov reactors uas siv cov khoom siv hluav taws xob los ntawm cov hlau.

Hluav taws xob lub cev muaj zog thiab kev lag luam tsav tsheb ua rau muaj kev loj hlob tsis tu ncua hauv qib siab - qib tsis - taw qhia steel.

Lub tshuab hluav taws xob cia thiab cov khoom siv hluav taws xob ntse tsim kev thov tshiab rau siab - zaus thiab nyias- ntsuas hluav taws xob hlau.

Lub peev xwm nthuav dav yog tsom rau hauv cov kab txias - dov cov kab ntau lawm, thaum kub - dov hluav taws xob hlau txuas ntxiv mus.

FAQ

1. Qhov txawv ntawm CGO thiab HiB hluav taws xob hlau yog dab tsi?

Ob leeg yog cov nplej- cov qhab-nees taw qhia. HiB steel muaj magnetic induction ntawm 800 A / m saum toj no txog 1.88 T, muab cov tub ntxhais poob qis thiab siab permeability dua CGO. HiB yog qhov zoo dua rau qis- poob thiab loj- muaj peev xwm transformers.

2. Vim li cas nplej - taw qhia steel siv rau transformers?

Transformer cores nqa flux nyob rau hauv ib qho kev taw qhia, thiab GO steel muaj nws cov khoom sib nqus zoo tshaj plaws raws li cov kev taw qhia dov. Qhov no maximizes flux ceev, minimizes core poob thiab txo transformer loj.

3. Cov lej ntawm cov hlau hluav taws xob txhais li cas?

Cov lej feem ntau encode qhov lav tsis tau hlau. Piv txwv li, qis dua - cov qhab nia nyob rau hauv tib lub series muaj qis dua thiab ntau dua sib nqus induction. Nco ntsoov xyuas tus qauv (GB/T 2521 lossis IEC 60404-8) siv rau kev faib tawm.

4. Lub tshuab hluav taws xob hlau tau hloov kho sai npaum li cas hauv khw?

Kev hloov kho yog tsav los ntawm cov qauv kev ua tau zoo rau kev faib cov khoom siv hluav taws xob, xws li cov qauv kev ua haujlwm tsawg kawg nkaus hauv kev lag luam loj, thiab los ntawm kev nthuav dav ntawm lub zog tauj dua tshiab thiab EV ntau lawm. High-qib HiB thiab nyias- ntsuas cov khoom lag luam loj hlob sai dua cov qib ib txwm muaj.

5. Dab tsi yog qhov kev cia siab rau cov uas tsis yog - taw qhia hluav taws xob hlau?

NGO steel xav tau zoo sib xws rau kev tsim lub cev muaj zog, suav nrog EV traction motors, muaj lub cev muaj zog thiab cov khoom siv hauv tsev, uas txhawb kev loj hlob tsis tu ncua hauv qib siab -NGO qib.

6. Kuv tuaj yeem nrhiav cov ntaub ntawv pov thawj hluav taws xob zoo li cas?

Cov ntaub ntawv txheeb cais los ntawm cov koom haum kev lag luam hauv tebchaws thiab tsoomfwv cov chaw lis haujlwm, xws li cov ntawv xov xwm tshaj tawm txhua xyoo, yog qhov tseem ceeb. Cov ntaub ntawv hais txog ntawm no (2021 cov zis ntawm 13.1828 lab tonnes hauv Suav teb) yog los ntawm kev lag luam pej xeem kev txheeb cais thiab yuav tsum tau hla -xyuas nrog cov ntawv tshaj tawm txhua xyoo.
