Yam khoom thiab kev loj hlob Trends ntawm Oriented Electrical Steel (Silicon Steel)

Zuag qhia tag nrho txoj kev loj hlob ntawm Oriented Electrical Steel

Grain-oriented hluav taws xob hlau, feem ntau hu ua oriented silicon steel, yog cov khoom tseem ceeb ntawm lub hwj chim transformers thiab loj rotating tshuab. Nws txoj kev loj hlob yog tsav los ntawm peb lub hom phiaj: qis hlau poob, siab dua magnetic induction thiab thinner gauge. Cov kev txhim kho no ncaj qha txo qhov tsis muaj - thauj khoom poob ntawm cov hloov pauv, uas yog them rau tus neeg teb xov tooj rau tag nrho lub neej ntawm cov cuab yeej, yog li txawm tias qhov txo qis me me hauv watts ib kilogram txuag tau ntau lub zog thoob plaws lub nkoj hloov pauv.

Cov qhab nia thiab kev ntsuam xyuas tau raug teev tseg hauv cov qauv xws li GB/T 2521 thiab IEC 60404, nrog kev poob ntsuas los ntawm Epstein txoj kev ntawm 1.7 T thiab 50 Hz, thiab tib lub moj khaum siv rau nyias thiab siab - qib induction tau piav qhia hauv qab no.

Ultra-Low Iron Loss Technologies

Peb cov thev naus laus zis ntau lawm thawb cov tub ntxhais poob qis.

Sib nqus domain refinement: laser scribing los yog zoo sib xws kev kho mob subdivides cov sib nqus domains ntawm lub strip nto. Qhov no txo ​​qis qhov tsis txaus ntseeg tam sim no poob thiab txo qis tag nrho cov tub ntxhais poob ntawm cov nplej- taw qhia cov hlau los ntawm 10% mus rau 20%.

Depositional nro txheej: siab - nro inorganic txheej siv rau ob qhov chaw txo qhov poob ntawm ib chav tsev qhov hnyav ntawm daim ntawv thiab kuj pab txhim kho cov stacking yam thiab tuav tus cwj pwm.

Thinner gauges: txo thickness ntawm 0.30 hli thiab 0.27 hli mus rau 0.23 hli, 0.20 hli thiab thaum kawg 0.15 hli txiav eddy tam sim no poob sharply, vim eddy poob teev nrog lub square ntawm lub thickness. A 0.20 hli qib yog cov qauv mos sib nqus khoom siv rau 400 Hz magnetic circuits xws li cov khoom siv dav hlau thiab cov khoom siv hluav taws xob hauv hiav txwv, kev sib txuas siab induction nrog tsawg poob ntawm qhov siab.

Ultra-High Magnetic Induction Qib

High sib nqus induction tso cai rau lub transformer designer los tsa lub ua hauj lwm flux ceev, uas txo cov tub ntxhais ntoo khaub lig-section thiab yog li qhov loj thiab qhov hnyav ntawm transformer rau tib lub zog. Siv ob npaug los yog triple recrystallization, los yog siab -kub gradient annealing txheej txheem, cov qib niaj hnub ua tiav cov hlau nplaum polarization B8 ntawm 1.95 T txog 2.0 T ntawm lub zog ntawm 800 A / m. High- qib induction tau teev nyob qhov twg qhov kev hloov pauv qhov hnyav thiab qhov ntev yog qhov tseem ceeb, xws li hauv UHV cov khoom siv kis tau tus mob thiab cov tshuab hluav taws xob loj.

Dual-Kev taw qhia thiab 6.5% Si Qib

Fine-grained dual-kev taw qhia silicon steel yog tsim los ntawm silicon- oxide decarburization txoj kev thiab txhim kho lub cubic zoo nkauj, yog li nws qhia tau hais tias siab induction nyob rau hauv ob qho tib si dov kev taw qhia thiab transverse kev taw qhia. Nws B8 nce mus txog 1.85 T txog 1.90 T nyob rau hauv ob qho tib si cov lus qhia, nrog core poob P1.7/50 hauv qab 1.02 W / kg ntawm 0.30 mm thickness, thiab magnetostriction yog tsawg nyob rau hauv ob qho tib si qhia. Cov khoom no yog txaus siab rau rotating tshuab thiab tshwj xeeb cores qhov twg flux kev taw qhia hloov tsis tu ncua.

Thaum cov ntsiab lus silicon tau nce mus rau 6.5 wt%, cov khoom mus txog ze rau -zero magnetostriction, hluav taws xob tiv taus ntau dua thiab qis dua tam sim no poob, muab kev ua tau zoo ntawm kev nce zaus. High-silicon steel yog li ntawd tus neeg sib tw zoo tshaj plaws rau qis- suab nrov, qis- poob siab- zaus transformers thiab reactors, thiab nws tseem yog ib qho kev tshawb fawb lub ntsiab lus vim hais tias cov ntsiab lus silicon siab ua rau lub strip nkig thiab nyuaj rau yob.

Daim ntawv thov teb

High-kev ua tau zoo zog transformers: UHV kis tau tus mob transformers thiab tis transformers uas yuav tsum tau raws li nruj tsis muaj - load poob txwv.

Cov khoom siv hluav taws xob tshiab: cua thiab hnub ci inverters thiab siab - zaus transformers rau EV charging pawg.

High-kawg cov khoom siv hluav taws xob: precision ntsuas transformers thiab siab- zaus reactors qhov uas tsis tshua muaj magnetostriction thiab kev ua haujlwm ruaj khov.

Cov Lus Qhia Txog Kev Tshawb Fawb Yav Tom Ntej

Inhibitor-free grain-oriented steel, uas zam cov pa inhibitor chemistry, tso cai rau qis slab cua sov kub thiab tshem tawm cov kauj ruam decarburization, thiab nws cov khoom tau ua ib feem ntawm kev tsim khoom. Kev ua haujlwm ntxiv yog xav tau ntawm cov strips nyias hauv qab 0.1 hli uas tsim los ntawm triple recrystallization, taw qhia cov hlau ntshiab hlau nrog siab saturation induction, thiab siab - rwb thaiv tsev, tsis yog - pa phem rwb thaiv tsev thiab coatings coatings. Cov kev txhim kho no tsom rau tib lub hom phiaj: qis dua, siab dua induction thiab thinner gauge rau tiam tom ntej ntawm lub zog- cov khoom siv hlau nplaum zoo.

FAQ

B8 txhais li cas hauv cov nplej -cov lus qhia tshwj xeeb steel?

B8 yog qhov sib nqus polarization ntsuas ntawm lub zog sib nqus ntawm 800 A / m. Nws qhia tau hais tias cov khoom siv tau yooj yim npaum li cas tuaj yeem sib nqus thiab qhov siab npaum li cas ntawm cov tub ntxhais tuaj yeem ncav cuag, nrog cov txiaj ntsig xws li 1.82 T rau qib sib xws thiab mus txog 2.0 T rau qib siab -induction.

Yog vim li cas thinner silicon steel zoo dua rau siab - zaus transformers?

Eddy tam sim no poob nce nrog lub square ntawm lub strip thickness, yog li halving lub thickness thiaj li eddy tivthaiv los ntawm ib tug tseem ceeb ntawm plaub. Cov qib thinner xws li 0.20 mm thiab 0.15 mm yog li qhov tseem ceeb ntawm 400 Hz thiab siab dua.

Yuav ua li cas magnetic domain refinement txo core poob?

Laser lossis mechanical kho subdivides lub loj sib nqus domains rau hauv me me, uas shortens txoj kev ntawm domain phab ntsa txav thiab txo cov anomalous eddy tam sim no poob. Tag nrho cov tseem ceeb poob ntawm cov nplej- taw qhia steel poob los ntawm 10% mus rau 20%.

Dab tsi yog tshwj xeeb txog 6.5% silicon steel?

Ntawm 6.5 wt% silicon lub magnetostriction mus zero, resistivity yog siab thiab eddy tam sim no poob yog tsawg, yog li cov khoom nyob ntsiag to thiab npaum ntawm cov zaus. Lub drawback yog brittleness, uas ua rau dov thiab tuav nyuaj.

Qib twg yuav tsum raug xaiv rau lub tshuab hluav taws xob faib khoom?

Rau 50 Hz faib transformers, ntau qib xws li 23Q110 lossis 27Q120 muab qhov sib npaug thiab cov nqi. Yog tsis muaj-load poob dominates tus nqi khiav hauj lwm, domain-refined los yog siab- qib induction nrog poob qis dua 0.9 W/kg yog qhov tsim nyog.

P1.7/50 yog dab tsi?

Nws yog qhov tshwj xeeb tag nrho cov tub ntxhais poob hauv watts ib kilogram ntsuas ntawm lub ncov polarization ntawm 1.7 T thiab zaus ntawm 50 Hz siv Epstein thav duab, tus qauv piv rau cov nplej - taw qhia hluav taws xob hlau.
