Silicon hlauyog cov khoom siv sib nqus siv dav hauv kev lag luam transformer, suav nrog ob qho tib siCRNGO silicon hlauthiabCRGO silicon hlau, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov me me transformers thiab cov khoom siv hauv tsev.
Raws li rau cov neeg muas zaub, paub txog lub ntsiab yam tseem ceeb uas cuam tshuam cov electromagnetic zog ntawmsilicon steel ntawvtuaj yeem ua rau nws yooj yim dua kom haum cov kev xav tau nrog cov khoom siv silicon steel.
Ntu 1 - Qhov cuam tshuam ntawm alloying ntsiab ntawm electromagnetic zog
Cov tshuaj muaj pes tsawg leeg hauv silicon steel, tshwj xeeb tshaj yog cov ntsiab lus ntawm cov hlau alloying xws li Si thiab C, tau raug pov thawj tseem ceeb los txhim kho cov khoom siv hluav taws xob ntawm silicon steel ntawv.
--- Silicon cov ntsiab lus
Silicon muaj qhov cuam tshuam rau cov khoom siv hluav taws xob, uas ua rau muaj kev tiv thaiv thiab txo qhov poob tam sim no. Silicon kuj tuaj yeem txhawb nqa ferrite grain coarsening, txo kev coercivity, txo cov anisotropy ntawm cov siv lead ua, yog li magnetization nce thiab hysteresis poob qis. Lub silicon steel ntawv muaj zog sib nqus inductance nyob rau hauv tsis muaj zog magnetic teb. Hloov chaw, nyob rau hauv lub zog sib nqus, silicon txo qhov sib nqus inductivity ntawm hlau vim saturation magnetic inductivity txo los ntawm 500 Gauss rau txhua txhua 1% silicon nce.
--- Cov ntsiab lus carbon
Cov pa roj carbon yog teeb meem rau cov khoom sib nqus ntawm silicon steel ntawv. Nws tsub kom coercivity thiab hysteresis poob, thiab txo qhov sib nqus sensation siv. Yog tias cov ntsiab lus carbon ntau tshaj 0.0296% hauv cov ntawv silicon steel tiav, qhov taw qhia ntawm silicon steel yuav raug puas tsuaj ib nrab lossis tag nrho thaum lub sij hawm kub annealing.
Yog li ntawd, rau GOES (grain oriented hluav taws xob hlau), yuav tsis muaj cov ntsiab lus siab carbon; thaum NGOES (tsis yog grain oriented hluav taws xob hlau), uas nws cov ntsiab lus carbon ntau tshaj 0.02%, tsis tuaj yeem siv los tsim cov khoom qib siab steel. Cov hlau poob nce ntxiv nrog cov ntsiab lus ntawm cov pa roj carbon monoxide hauv silicon steel ntawv.
Ntu 2 - Qhov cuam tshuam ntawm microstructures ntawm electromagnetic zog
--- Cov qoob loo loj
Qhov luaj li cas ntawm cov ntawv silicon steel nyob ntawm cov nplej tom qab annealing, uas feem ntau yog cov nplej ntawm ib cheeb tsam. Thaum lub sij hawm tsim khoom tiag tiag, yog tias cov nplej loj dhau lawm, tsis yog tag nrho cov pa roj carbon monoxide tuaj yeem ua rau cov carbides raws li cov ciam teb raws li qhov nws xav tau, qee cov pa roj carbon atoms tau yaj hauv cov ferrite raws li cov kev daws teeb meem interstitial. Yog li ntawd, raws li cov qoob loo loj zuj zus, cov hlau poob nce ntxiv.
--- Thickness ntawm daim ntawv
Lub thinner ntawm silicon steel ntawv, qhov me me qhov eddy tam sim no poob, thiab yog li qhov me me ntawm tag nrho cov tub ntxhais poob ntawm silicon steel ntawv. Yog li ntawd, silicon steel daim hlau feem ntau yog ua rau nyias nyias raws li xav tau. Raws li lub thickness ntawm steel phaj txo los ntawm {{0}}.5mm mus rau 0.2mm, B25 tus nqi txo qis; raws li qhov tuab txuas ntxiv mus rau {{10}}}10-0.05mm, B25 tus nqi txo qis dua. Qhov txawv ntawm B25 tus nqi ntawm 0.5mm thiab 0.05mm tuab kub dov transformer steel yog 500-1100 Gauss.
Ntu 3 - Qhov cuam tshuam ntawm kev ua cov txheej txheem ntawm cov khoom siv hluav taws xob
Non-oriented silicon steel txias dov txheej txheem
Kev dov ntawm silicon steel los xij muaj qhov cuam tshuam loj rau microstructure ntawm cov ntawv hlau tom qab annealing, thiab muaj qhov sib txawv loj hauv cov khoom siv hluav taws xob. Ordinary non-oriented silicon steel feem ntau yog tsim los ntawm thawj txias dov, thiab qib high-qib uas tsis yog-oriented silicon steel feem ntau yog tsim los ntawm theem nrab txias dov. Tom qab silicon steel yog txias-dov, ferrite nplej yuav loj dua thiab cov ciam teb yuav tsawg dua, yog li cov hlau nplaum kuj yuav qis dua thiab hysteresis poob yuav me dua.
