Cov yam ntxwv tseem ceeb ntawm silicon steel los xij muaj xws li hlau tsis muaj nqi, sib nqus flux ceev, hardness, flatness, thickness uniformity, txheej hom thiab punching zog, thiab lwm yam.
1.Iron poob nqi
Tsis tshua muaj hlau poob yog qhov tseem ceeb tshaj plaws qhia txog qhov zoo ntawm silicon steel los xij.Lub teb chaws txhua tus faib cov qhab nia raws li tus nqi hlau poob.Qhov qis hlau poob, qib siab dua.
2. Sib nqus flux ceev
Sib nqus flux ceev yog lwm yam khoom tseem ceeb ntawm cov khoom siv hluav taws xob ntawm silicon steel los xij, uas qhia tau hais tias qhov yooj yim ntawm cov ntaub ntawv silicon steel yog magnetized.Nyob rau hauv lub magnetic teb siv ntawm ib tug tej zaus, lub magnetic flux dhau los ntawm chav tsev yog hu ua magnetic flux ceev.Feem ntau qhov sib nqus flux ceev ntawm silicon steel los xij yog ntsuas ntawm qhov zaus ntawm 50 lossis 60 Hz thiab qhov sib nqus sab nraud ntawm 5000A / m.Nws yog hu ua B50, thiab nws chav tsev yog Tesla.
Qhov sib nqus flux ceev yog cuam tshuam nrog cov qauv sib xyaw, impurities, kev ntxhov siab sab hauv thiab lwm yam ntawm silicon steel ntawv.Sib nqus flux ceev ncaj qha cuam tshuam lub zog efficiency ntawm motors, transformers thiab lwm yam khoom siv hluav taws xob.Qhov siab dua qhov sib nqus flux ceev, qhov sib nqus flux ntau dua los ntawm chav tsev, thiab lub zog ua haujlwm zoo dua.Yog li ntawd, qhov siab dua qhov sib nqus flux ntom ntawm silicon steel ntawv, qhov zoo dua.Feem ntau, cov kev qhia tshwj xeeb tsuas yog xav tau qhov tsawg kawg nkaus ntawm qhov sib nqus flux ceev.
3. Hardness
Hardness yog ib qho ntawm cov yam ntxwv zoo ntawm silicon steel los xij.Thaum cov tshuab xuas nrig ntaus tsis siv neeg niaj hnub no yog cov ntawv xuas nrig ntaus, cov kev xav tau rau hardness yog nruj dua.Thaum lub hardness tsawg dhau, nws tsis haum rau kev ua haujlwm pub mis ntawm lub tshuab xuas nrig ntaus tsis siv neeg.Nyob rau tib lub sijhawm, nws yog qhov yooj yim los tsim cov burrs ntev ntev thiab ua kom lub sijhawm sib dhos.lub sij hawm nyuaj.Yuav kom ua tau raws li cov kev xav tau saum toj no, lub hardness ntawm silicon steel ntawv yuav tsum siab dua li ib qho nqi hardness.Piv txwv li, lub hardness ntawm 50AI300 silicon steel ntawv feem ntau yog tsis tsawg tshaj li HR30T hardness nqi 47. Lub hardness ntawm silicon steel los xij nce raws li qib nce.Feem ntau, cov ntsiab lus silicon ntau ntxiv rau qib siab qib silicon steel los xij, cov nyhuv ntawm cov tshuaj tiv thaiv ntxiv dag zog ntawm cov hlau ua rau lub hardness siab dua.
4. Flatness
Flatness yog ib qho tseem ceeb zoo ntawm silicon steel los xij.Zoo flatness yog qhov zoo rau kev ua yeeb yaj kiab thiab kev sib dhos ua haujlwm.Flatness yog ncaj qha thiab ze ze rau dov thiab annealing tshuab.Txhim kho dov annealing thev naus laus zis thiab cov txheej txheem muaj txiaj ntsig zoo rau flatness.Piv txwv li, yog siv cov txheej txheem nruam annealing, qhov flatness zoo dua li txheej txheem batch annealing.
5. Thickness uniformity
Thickness uniformity yog ib qho tseem ceeb heev tus yam ntxwv ntawm silicon steel los xij.Yog hais tias lub thickness uniformity tsis zoo, lub thickness sib txawv ntawm qhov nruab nrab thiab ntug ntawm cov hlau ntawv loj heev, los yog cov thickness ntawm cov hlau ntawv txawv ntau dhau ntawm qhov ntev ntawm cov ntawv hlau, nws yuav cuam tshuam cov thickness ntawm cov tub ntxhais sib dhos. .Cov tub ntxhais sib txawv muaj qhov sib txawv loj hauv cov khoom sib nqus permeability, uas cuam tshuam ncaj qha rau cov yam ntxwv ntawm cov motors thiab transformers.Yog li ntawd, qhov me me ntawm cov thickness variation ntawm silicon steel los xij, qhov zoo dua.Lub thickness uniformity ntawm steel los xij yog ze ze rau kub dov thiab txias dov tshuab thiab cov txheej txheem.Tsuas yog los ntawm kev txhim kho dov thev naus laus zis muaj peev xwm tuaj yeem txo qhov tuab ntawm cov nplooj ntawv steel.
6. Txheej zaj duab xis
Txheej zaj duab xis yog ib yam khoom tseem ceeb heev rau silicon steel los xij.Qhov saum npoo ntawm daim ntawv silicon steel yog chemically coated, thiab ib tug nyias zaj duab xis yog txuas rau nws, uas muaj peev xwm muab rwb thaiv tsev, xeb tiv thaiv thiab lubrication zog.Lub rwb thaiv tsev txo qhov eddy tam sim no poob ntawm silicon steel core nplooj ntawv;cov xeb tiv thaiv tiv thaiv cov ntawv hlau los ntawm xeb thaum ua thiab khaws cia;lubricity pab txhim kho cov punching kev ua tau zoo ntawm silicon steel los xij thiab txuas lub neej ntawm cov pwm.
7. Cov khoom siv ua yeeb yaj kiab
Punchability yog ib qho tseem ceeb ntawm cov yam ntxwv zoo ntawm silicon steel los xij.Cov khoom xuas nrig ntaus zoo txuas ntxiv lub neej ntawm cov pwm thiab txo cov burrs ntawm cov ntawv xuas nrig.Lub punchability yog ncaj qha ntsig txog cov txheej txheej thiab hardness ntawm silicon steel ntawv.Organic coatings muaj cov cuab yeej xuas nrig ntaus zoo, thiab cov txheej txheem tshiab tau tsim tshwj xeeb yog siv los txhim kho cov khoom xuas nrig ntaus ntawm cov ntawv silicon steel.Tsis tas li ntawd, yog hais tias lub hardness ntawm steel ntawv yog tsawg heev, nws yuav ua rau loj burrs, uas yog tsis conducive rau xuas nrig ntaus;tab sis yog tias qhov hardness siab dhau lawm, lub neej ntawm pwm yuav raug txo;Yog li ntawd, lub hardness ntawm silicon steel ntawv yuav tsum tau tswj nyob rau hauv ib tug tsim nyog ntau yam.
