Nyob rau hauv transformers, qhov yuav tsum tau rau kev ua tau zoo ntawm silicon steel feem ntau yog:

① Tsawg hlau poob, uas yog qhov tseem ceeb tshaj plaws qhia ntawm silicon steel ntawv zoo. Txhua lub teb chaws faib cov qhab nia raws li tus nqi poob hlau, qhov qis hlau poob, qib siab dua.

.Ntawm sib nqus induction siv (sib nqus induction) siab nyob rau hauv ib tug muaj zog magnetic teb, uas txo lub ntim thiab hnyav ntawm cov hlau core ntawm lub cev muaj zog thiab transformer, thiab txuag silicon steel nplooj ntawv, tooj liab xov hlau thiab insulating cov ntaub ntawv.

③ Qhov saum npoo yog du, tiaj tus thiab tsis sib xws hauv cov tuab, uas tuaj yeem ua rau muaj qhov ua kom zoo dua ntawm cov tub ntxhais.

④ Muaj peev xwm xuas nrig ntaus thiab ua haujlwm yooj yim.

⑤ Lub adhesion thiab weldability ntawm qhov chaw insulating zaj duab xis yog qhov zoo, uas tuaj yeem tiv thaiv corrosion thiab txhim kho kev ua haujlwm ntawm xuas nrig ntaus.

⑥ Yeej tsis muaj hlau nplaum laus.

Classification thiab qib txhais ntawm silicon steel ntawv

Transformers feem ntau siv txias-kuav los tiag grain-oriented silicon steel ntawv los xyuas kom meej lawv tsis muaj-load zog efficiency theem. Cold-rolled grain-oriented silicon steel los xij tuaj yeem muab faib ua cov ntawv txias-kuav los tiag-qhib silicon steel los xij, siab sib nqus permeability silicon steel nplooj ntawv (los yog siab sib nqus induction silicon steel nplooj), thiab laser-cim silicon steel los xij raws li kev ua tau zoo. thiab cov txheej txheem ua. Feem ntau, nyob rau hauv alternating magnetic teb (tus nqi ncov) ntawm 50Hz thiab 800A, silicon steel ntawv nrog qhov tsawg kawg nkaus sib nqus polarization B800A = 1.78T～1.85T ntawm cov tub ntxhais hlau yog hu ua zoo tib yam silicon steel ntawv, uas yog sau tseg raws li “CGO” , thiab B800A = 1.85T lossis ntau dua Cov ntawv silicon steel tau sau tseg raws li qhov siab sib nqus permeability silicon steel ntawv (siab sib nqus induction silicon steel ntawv), thiab raug kaw ua “Hi-B steel”. Lub ntsiab sib txawv ntawm Hi-B steel thiab cov pa silicon steel ntawv yog: Gaussian azimuthal kev ntxhib los mos ntawm Hi-B steel Qib ntawm silicon steel yog siab heev, uas yog, kev taw qhia ntawm silicon steel nplej nyob rau hauv cov kev taw qhia ntawm yooj yim magnetization yog heev. siab. Hauv kev lag luam, cov txheej txheem recrystallization thib ob yog siv los tsim cov ntawv silicon steel nrog cov ntsiab lus silicon ntawm 3%. Qhov kev taw qhia ntawm cov pob zeb ntawm Hi-B steel Qhov nruab nrab sib txawv ntawm qhov kev taw qhia dov yog 3 °, thaum cov ntawv zoo tib yam silicon steel yog 7 °, uas ua rau Hi-B steel muaj qhov sib nqus permeability siab dua, feem ntau nws B800A tuaj yeem ncav cuag ntau dua 1.88T, uas. txhim kho Gaussian azimuth kev ntxhib los mos thiab sib nqus permeability txo cov hlau tsis zoo. Lwm qhov tshwj xeeb ntawm Hi-B steel yog qhov elastic nro ntawm cov iav zaj duab xis thiab cov txheej txheej insulating txuas rau saum npoo ntawm cov ntawv hlau yog 3 ~ 5N / mm2, uas yog qhov zoo dua li 1 ~ 2 N / mm2 ntawm cov qauv zoo tib yam silicon steel. daim ntawv, thiab qhov nro ntawm cov hlau sawb yog Lub siab nro txheej tuaj yeem txo qhov sib nqus qhov dav thiab txo qhov txawv txav tam sim no poob. Yog li ntawd, Hi-B steel muaj qis hlau tsis muaj nqi tshaj li cov lus pom zoo ntawm cov ntawv cilicon steel.

Lub laser-cim silicon steel daim ntawv yog raws li nyob rau hauv Hi-B steel, thiab los ntawm laser beam irradiation technology, nws ua ib tug me me strain nyob rau saum npoo, ntxiv refines lub sib nqus axis, thiab ua tiav cov hlau tsis muaj zog. Laser-cim silicon steel nplooj ntawv tsis tuaj yeem raug muab tshem tawm, vim tias cov nyhuv ntawm kev kho laser yuav ploj mus yog tias qhov kub nce ntxiv.

Lub cev lub cev ntawm silicon steel los xij ntawm cov qib sib txawv yog qhov zoo ib yam, thiab qhov ceev yog 7.65g / cm3. Rau tib hom silicon steel los xij, qhov sib txawv tseem ceeb hauv kev ua tau zoo thiab kev ua haujlwm zoo nyob hauv cov ntsiab lus silicon thiab kev cuam tshuam ntawm cov txheej txheem ntau lawm.
