Dab tsi yog silicon steel thiab dab tsi yog kev faib tawm ntawm silicon steel?

 Cov ntsiab lus sib txawv ntawm silicon: tsawg silicon thiab siab silicon.

1. Tsawg silicon wafer: Tsawg silicon wafer muaj tsawg dua 2.8% silicon. Nws muaj qee yam kev siv lub zog thiab feem ntau yog siv los tsim cov motors, feem ntau hu ua lub cev muaj zog silicon steel los xij.

2. High silicon wafer: High silicon wafer muaj 2.8% -4.8% silicon. Nws muaj cov khoom sib nqus zoo tab sis yog nkig. Nws yog tsuas yog siv los ua transformer cores, feem ntau hu ua transformer silicon steel nplooj ntawv. Tsis muaj kev txwv nruj ntawm ob qho tib si hauv kev siv tiag tiag. High silicon wafers feem ntau yog siv los ua cov motors loj.

 Kev faib cov txheej txheem ntau lawm: kub dov thiab txias dov

1. Kub dov silicon steel: Nws yog tsuas yog siv nyob rau hauv generator manufacturing, yog li nws tseem hu ua kub dov lub cev muaj zog silicon steel. Nws yog tsim los ntawm kub-dov cov khoom mus rau qhov yuav tsum tau thickness thiab ces annealing nws ntawm 800 degree ~ 850 degree. Vim nws qhov kev ua tau zoo thiab kev siv tsis zoo, nws tau maj mam tshem tawm ntawm kev ua lag luam hauv xyoo tas los no.

2. Cold-rolled silicon steel, txias-dov los xij muaj cov tuab tuab, zoo nto zoo thiab muaj zog sib nqus. Yog li ntawd, nrog rau txoj kev loj hlob ntawm kev lag luam, cov ntaub ntawv kub-kuav los tiag yuav raug hloov los ntawm cov ntawv txias-dov.Cold rolled silicon steel tuaj yeem muab faib ua ob hom: grain non-oriented silicon steel thiab grain oriented silicon steel.

 (1) Silicon cov ntsiab lus
Ob leeg yog txias-dov silicon steel los xij, tab sis cov ntsiab lus silicon txawv. Cov ntsiab lus ntawm silicon ntawm txias-kuav los tiag uas tsis yog-oriented silicon steel nplooj ntawv yog 0.5%-3.0%, hos cov ntsiab lus silicon ntawm txias-dov taw qhia silicon steel nplooj ntawv siab tshaj 3 0%.

 (2) Xwm

Oriented silicon steel: Oriented silicon steel tseem hu ua txias-kuav los tiag transformer steel. Oriented silicon steel muaj zog directional magnetism, nrog rau qhov qis tshaj hlau poob nyob rau hauv lub dov kev taw qhia, lub siab tshaj plaws magnetic permeability, thiab ib tug siab sib nqus induction nqi nyob rau hauv ib tug tej yam magnetizing teb. Cov ntsiab lus ntawm silicon ntawm oriented silicon steel yog hais txog 3%, thiab cov ntsiab lus ntawm oxide inclusions nyob rau hauv cov hlau yuav tsum tau tsawg, thiab nws yuav tsum muaj ib co inhibitors (MnS, A1N). Nws yog ib qho tseem ceeb ferrosilicon alloy siv nyob rau hauv lub transformer (hlau core) manufacturing kev lag luam.

Non-oriented silicon steel: Non-oriented silicon steel yog ferrosilicon alloy uas muaj 0.8% -4.8% silicon, uas yog kub dov thiab txias dov rau hauv silicon steel los xij nrog tuab tsawg dua 1 mm. Ntxiv silicon tuaj yeem ua rau kom muaj kev tiv thaiv thiab siab tshaj plaws sib nqus permeability ntawm hlau, txo qis quab yuam, core poob (hlau poob) thiab sib nqus aging. Non-oriented silicon steel yog ferrosilicon alloy nrog cov ntsiab lus qis heev. Nyob rau hauv cov hlau phaj tom qab deformation thiab annealing, nws cov nplej tau muab faib rau hauv ib qho kev taw qhia tsis xwm yeem.

 (3) Cov txheej txheem ntau lawm

Oriented silicon steel: Oriented silicon steel yog smelted nyob rau hauv ib tug oxygen converter, thiab cov hlau billet yog dov mus rau hauv lub tiav thickness los ntawm kub dov, normalizing, txias dov, intermediate annealing thiab theem nrab txias dov, thiab ces undergoes decarburization annealing thiab kub annealing, thiab thaum kawg coated nrog ib txheej insulating.

Non-oriented silicon steel: Pre-desulfurization ntawm cov hlau kub, theem nrab desulfurization los ntawm kev ntxiv Ca0+CaF: flux los yog tsawg lub ntiaj teb cov ntsiab lus thiab calcium thaum lub sij hawm converter tshuab. Boiling molten steel yog ntxiv desulfurized tom qab kev kho lub tshuab nqus tsev thiab decarburization. Ferrosilicon nrog qis titanium thiab zirconium cov ntsiab lus raug xaiv rau alloying.

 (4) Cov qauv qoob loo

Cov nplej ntawm oriented silicon steel yog teem rau hauv ib qho kev txiav txim thiab feem ntau yog siv nyob rau hauv transformer cores thiab ib co motors.

Cov nplej ntawm cov hlau tsis-oriented silicon yog teem rau hauv kev tsis sib haum xeeb. Nws yog tsuas yog siv nyob rau hauv stators thiab rotors ntawm motors, compressors, loj hydro-turbine generators thiab lwm yam khoom siv.

 (5) Kev ua haujlwm thiab kev siv

Vim muaj cov khoom sib txawv ntawm ob, muaj qhov sib txawv ntawm lawv cov lus qhia siv.

Kev siv lub ntsiab ntawm txias-kuav los tiag uas tsis yog-oriented silicon steel los xij yog nyob rau hauv lub tshuab tsim hluav taws xob, yog li nws tseem hu ua txias-dov lub cev muaj zog silicon steel.

Kev siv lub ntsiab ntawm txias-dov oriented silicon steel sawb yog nyob rau hauv transformer manufacturing, yog li nws tseem hu ua txias-dov transformer silicon steel.

1. Tsis tshua muaj hlau poob. Qhov taw qhia tseem ceeb tshaj plaws ntawm kev ua tau zoo. Txhua lub teb chaws hauv ntiaj teb muab cov qhab nia raws li cov nqi hlau poob. Qhov qis hlau poob, qib siab dua thiab qhov zoo dua.
2. Siab sib nqus induction siv. Silicon steel los xij uas tuaj yeem tau txais kev sib nqus ntau dua nyob rau hauv tib qhov chaw sib nqus tuaj yeem ua rau lub cev muaj zog lossis transformer core ua los ntawm nws me me thiab hnyav, uas tuaj yeem txuag silicon steel los xij, tooj liab thiab cov ntaub ntawv rwb thaiv tsev.
3. High stacking coefficient. Qhov saum npoo ntawm cov ntaub ntawv silicon steel yog du, tiaj tus thiab tsis sib xws hauv cov tuab, uas txhim kho qhov sib npaug coefficient ntawm cov tub ntxhais.
4. Zoo punching kev ua tau zoo. Qhov no yog qhov tseem ceeb tshaj rau kev tsim cov me me thiab micro lub cev muaj zog cores.
5. Qhov saum npoo muaj qhov zoo adhesion thiab weldability rau cov zaj duab xis insulating, uas tuaj yeem tiv thaiv corrosion thiab txhim kho kev ua haujlwm ntawm kev xuas nrig ntaus.
6. Me me sib nqus aging tshwm sim. Silicon steel los xij yuav tsum tau xa tom qab annealing thiab pickling.

   Los xaus. Silicon steel yog siv los tsim cov cua turbines, cov khoom siv hluav taws xob hnub ci, thiab lwm yam, los txhim kho cov khoom siv thiab txo qis zog. Ntxiv rau qhov kev siv tseem ceeb saum toj no, silicon steel kuj tau siv dav hauv tsheb fais fab, cov cuab yeej hluav taws xob, khoom siv hauv tsev thiab lwm yam. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis tsis tu ncua, silicon steel yuav muaj ntau yam kev siv hauv kev lag luam hluav taws xob thiab hluav taws xob kom tau raws li qhov xav tau loj hlob. Yog li ntawd, raws li ib qho tseem ceeb ntawm cov khoom siv electromagnetic, silicon steel muaj cov ntawv thov tseem ceeb heev thiab kev lag luam xav tau.

Lo lus nug:

Hlau poob yog dab tsi?

Hlau poob (tseem hu ua core poob) yog hais txog lub zog poob hauv cov tub ntxhais hlau ntawm cov khoom siv hluav taws xob xws li transformers, inductors, AC motors, thiab AC generators vim yog qhov cuam tshuam ntawm kev hloov magnetic teb ntawm cov tub ntxhais sib nqus. Lub zog poob yog dissipated li cua sov thiab qee zaum raws li suab nrov.

Hlau poob tuaj yeem muab faib ua peb hom: hysteresis poob, eddy-tam sim no poob, thiab anomalous poob.
