Silicon Steel yog dab tsi thiab vim li cas nws thiaj siv dav?
Silicon steel, tseem hu ua hluav taws xob hlau lossis lamination steel, yog hlau - silicon alloy muaj kwv yees li 0.5% mus rau 3.5% silicon los ntawm qhov hnyav. Ntxiv silicon nce hluav taws xob tiv thaiv, uas ua rau txo qis eddy-tam sim no poob nyob rau hauv alternating magnetic teb, thaum ib tug ua tib zoo tswj cov txheej txheem metallurgical tsim cov hlau nplaum zoo nkauj uas muab cov khoom nws tsis muaj core poob thiab siab permeability. Vim hais tias ntawm cov khoom no, silicon steel yog cov khoom siv hlau nplaum uas tseem ceeb hauv lub zog thiab cov khoom siv hluav taws xob ua haujlwm ntawm 50 Hz lossis 60 Hz, los ntawm cov khoom me me -horsepower motors mus rau lub tshuab hluav taws xob loj thiab cov cores transformer. Cov khoom siv yog muab rau hauv cov ntawv nyias, feem ntau 0.23 hli mus rau 0.50 hli tuab, uas yog xuas nrig ntaus lossis txiav rau hauv laminations thiab stacked los tsim cov cores.
Daim ntawv thov tseem ceeb ntawm Silicon Steel
Silicon steel daim ntaub ntawv tuaj yeem muab faib ua tsib thaj chaw loj, txhua qhov muaj cov kev xav tau sib txawv thiab qhov tseem ceeb ntawm kev ua haujlwm.
1. Loj-Nqe Electromechanical Equipment
Cov cuab yeej tsim hluav taws xob xws li cua turbines, thermal generators thiab hydropower units siv tsis yog -qhia silicon steel los tsim generator stator thiab rotor cores. Cov khoom siv ua kom muaj kev hloov pauv hluav taws xob zoo thiab ncaj qha txhim kho lub zog tsim hluav taws xob. High- muaj peev xwm generators feem ntau qhia nruab nrab mus rau qib siab uas tsis yog- taw qhia steel nrog nruj thickness thiab flatness kam rau ua vim hais tias cov tub ntxhais poob nyob rau hauv loj heev active masses.
2. Cov khoom siv hauv tsev
Lub cev muaj zog hauv cov khoom siv hauv tsev xws li tshuab ntxhua khaub ncaws, kiv cua thiab cov twj siv tsis yog - taw qhia silicon steel. Txawm hais tias kev siv ib chav tsev me me, qhov loj tshaj txhua xyoo tso tawm ntawm cov khoom siv hauv tsev ua rau ntu no yog ib qho ntawm cov neeg siv khoom loj tshaj plaws ntawm cov khoom siv hluav taws xob. Cua- cua txias compressor motors yog ib qho piv txwv tseem ceeb: raws li kev tswj hwm kev siv hluav taws xob nruj, qhov kev thov rau qib siab - qib tsis- taw qhia silicon steel nrog qis tshwj xeeb cov tub ntxhais poob tau nce ntau.
3. Lub Tsheb Hluav Taws Xob Tshiab
Traction tsav motors ntawm lub zog tshiab tsheb xav tau silicon steel nrog kev sib xyaw ua ke ntawm cov hlau nplaum sib nqus, cov tub ntxhais tsis tshua muaj kev poob qis ntawm cov zaus siab thiab lub zog zoo txhua yam. Txhawm rau txhim kho kev ua haujlwm ntawm lub cev muaj zog thiab lub zog ntom ntom, stator thiab rotor cores yeej siv siab - qib tsis yog - silicon steel taw qhia, ua kom muaj kev ua haujlwm tau zoo nyob rau tag nrho qhov nrawm. Ntau lub EV motors kuj siv cov laminations nyias (0.25 mm lossis 0.20 mm) kom txo tau siab -frequency eddy-tam sim no poob thaum lub sij hawm siab -kev sib hloov ceev.
4. Muaj me me thiab nruab nrab-Sized Electromechanical Equipment
Lub cev muaj zog rau cov khoom siv xws li dov mills, cranes, compressors thiab cov cuab yeej siv tshuab yuav tsum tau siv cov silicon steel cores los muab lub zog siab thiab txhim khu kev qha hauv qab hnyav. Cov ntawv thov no ua haujlwm hauv cov xwm txheej hnyav, yog li cov hlau yuav tsum sib txuas cov khoom sib nqus ruaj khov nrog kev xuas nrig ntaus zoo thiab cov khoom siv sib xws.
5. Transformers, converters thiab zoo li qub Devices
Grain-taw qhia txog silicon steel (CRGO) feem ntau yog siv hauv transformer cores, tam sim no transformers thiab reactors. Nrog rau kev nce qib ntawm cov phiaj xwm hluav taws xob, ultra- cov phiaj xwm xa hluav taws xob siab thiab cov qauv siv hluav taws xob nruj dua, qhov kev thov rau siab -magnetic-induction grain- taw qhia silicon steel txuas ntxiv mus. Rau kev faib khoom thiab fais fab transformers, qib kev xaiv ncaj qha txiav txim siab tsis muaj -load poob raws li cov qauv xws li GB 20052-2024 thiab IEC 60076-20.
Cov yam ntxwv tseem ceeb uas tsav daim ntawv thov xaiv
Cov khoom sib nqus zoo heev: cov permeability siab txo qis kev sib nqus Circuit Court tsis kam, thiab tsis tshua muaj hlau tsis zoo (hysteresis poob ntxiv rau eddy-tam sim no poob) txo cov khoom siv zog thiab kub nce.
Cov txheej txheem muaj zog adaptability: silicon steel tuaj yeem dov rau hauv cov ntawv nyias hauv qab 1 hli; txias- cov khoom dov muaj cov tuab tuab, ib qho chaw tiaj tus thiab zoo xuas nrig ntaus, haum rau kev tsim khoom loj ntawm lub cev muaj zog thiab cov tshuab hluav taws xob lamination.
Kev ruaj ntseg siab: silicon steel qhia yuav luag tsis muaj kev laus sib nqus, yog li cov khoom sib nqus tsis lwj tom qab siv sijhawm ntev -, uas haum rau cov khoom tsim los rau ntau xyoo ntawm kev ua haujlwm tsis tu ncua.
Cov qoob loo-Txoj kev vs Tsis yog- Kev Taw Qhia: Yuav Xaiv Li Cas
Grain-qhia silicon steel yog ua tiav kom cov pob zeb siv lead ua tau zoo nyob rau hauv cov kev taw qhia dov, muab cov tub ntxhais poob qis heev thiab siab permeability thaum txoj kev flux ua raws li cov kev taw qhia dov. Yog li ntawd nws yog siv rau transformer cores, qhov twg flux kev taw qhia yog tswj los ntawm core geometry. Tsis yog-qhia silicon steel muaj cov qauv sib nqus isotropic thiab siv qhov twg cov kev taw qhia flux tig, xws li lub cev muaj zog stators thiab rotors. Raws li txoj cai ntawm tus ntiv tes xoo: yog tias qhov sib nqus hluav taws xob zoo li qub thiab kev taw qhia, xaiv cov nplej- cov qib taw qhia; yog nws rotates, xaiv tsis yog - qib taw qhia.
Common Silicon Steel Qib thiab Cov Khoom Zoo
Cov lus hauv qab no teev cov neeg sawv cev ntawm cov qoob loo-cov qhab nia taw qhia thiab lawv cov txiaj ntsig tau lees paub, hais txog cov kev ntsuas ntawm GB/T 2521.1-2016 thiab GB/T 2521.2-2016. Core poob yog ntsuas ntawm 1.7 T thiab 50 Hz tshwj tsis yog hais tias lwm yam; induction yog ntsuas ntawm 800 A / m (B800). Cov ntawv pov thawj tiag tiag ua raws li daim ntawv pov thawj zeb xeem ntawm txhua lub kauj.

Cov qib nrog cov lej poob qis feem ntau raug nqi ntau dua tab sis xa qis dua tsis muaj-load poob hauv qhov hloov pauv tiav, uas yog vim li cas tus nqi hloov pauv hloov pauv tau teev npe - ua kom zoo lossis siab - qib induction rau qib 1 lub zog ua haujlwm.
Daim ntawv thov thiab cov kev xav tsis zoo
Tsis txhob txiav txim ib qib los ntawm thickness: ib tug 0.23 hli pa qib yuav muaj siab poob siab tshaj 0.27 hli siab - qib induction. Ib txwm sib piv tus nqi lav W / kg ntawm tib qhov induction thiab zaus.
Kov thiab txiav taw qhia cov hlau raws li cov kev taw qhia dov rau transformer cores; txiav tawm ntawm dov kev taw qhia degrades sib nqus kev ua tau zoo thiab ua kom nrov nrov.
Stacking yam tseem ceeb: qis stacking yam txhais tau hais tias ib qho me me ua haujlwm hla-section thiab flux ceev dua rau tib lub ntim ntim, uas ua rau cov tub ntxhais poob thiab magnetizing tam sim no.
Annealing tom qab txiav yog pom zoo rau punched transformer laminations los txo cov neeg kho tshuab kev nyuaj siab qhia los ntawm shearing thiab xuas nrig ntaus.
FAQ
Dab tsi yog qhov txawv ntawm silicon steel thiab cov hlau zoo tib yam?
Silicon steel muaj 0.5-3.5% silicon, uas ua rau kom muaj hluav taws xob tiv taus thiab txo qhov eddy-tam sim no poob hauv alternating teb. Nws kuj tseem ua tiav los tsim kom muaj kev sib nqus zoo nkauj, yog li nws qhov kev poob qis yog ib feem me me ntawm cov hlau tsis tshua muaj carbon tsawg.
Dab tsi yog qib silicon steel siv rau transformer cores?
Transformer cores siv grain - taw qhia silicon steel, feem ntau qib ntawm 0.23 hli mus rau 0.30 hli thickness. Kev faib tawm transformers feem ntau siv cov qib xws li 23Q110, 27QG100 lossis domain- cov qib ua kom zoo zoo li 23RK085 nyob ntawm cov chav kawm siv hluav taws xob xav tau.
Yog vim li cas lub cev muaj zog cores siv tsis yog - taw qhia silicon steel?
Nyob rau hauv motors lub magnetic flux rotates nrog rotor txoj hauj lwm, yog li cov khoom siv tseem ceeb yuav tsum muaj cov khoom sib nqus sib nqus hauv txhua qhov kev qhia. Tsis yog -qhia silicon steel yog isotropic thiab yog li tsim nyog rau stator thiab rotor laminations.
Puas yog siv qib qis dua - poob qis ib txwm txhim kho lub cev muaj zog?
Tsis proportionally. Core poob yog ib feem ntawm tag nrho lub cev muaj zog poob; winding tooj liab poob, kev sib txhuam thiab windage kuj tseem ceeb. qis dua -cov hlau tsis zoo txhim kho kev ua haujlwm zoo tshaj plaws hauv cov motors nrog lub luag haujlwm siab thiab kev ua haujlwm siab, xws li compressor thiab traction motors.
Silicon steel cores puas tuaj yeem siv dua lossis rov siv dua?
Silicon steel seem yog tag nrho recyclable thiab yog ib qho tseem ceeb cov tswv yim rau hluav taws xob steelmaking. Laminations los ntawm scrapped transformers thiab motors yog niaj hnub sau; Txawm li cas los xij, cov cores yuav tsum tsis txhob rov qab siv ncaj qha rau hauv cov cuab yeej tshiab vim tias txiav thiab rhuav tshem cov khoom sib nqus thiab cov txheej txheem rwb thaiv tsev.
