Raws li cov lus tshaj tawm raug cai thaum Lub Kaum Ob Hlis 17, 2021, European Commission tau pib ua ib qho…
Cov hlau hluav taws xob tsis yog-taw qhiafeem ntau muaj 2% -3.5% silicon. Nws muaj cov khoom sib nqus zoo sib xws hauv txhua qhov kev taw qhia, qhov hu ua isotropy.Cov hlau nplaum hluav taws xobfeem ntau muaj 3% silicon thiab ua tiav rau hauv txoj kev uas tsim cov khoom xav tau hauv qhov kev taw qhia dov. Cov hlau tsis yog-grain oriented steel (CRNGO) pheej yig dua li cov hlau tsis yog-grain oriented steel (CRGO). CRNGO tuaj yeem siv rau cov ntawv thov uas muaj nqi qis dua qhov twg qhov kev taw qhia ntawm magnetic flux tsis ruaj khov, xws li cov motors thiab generators. CRGO feem ntau yog nyob rau hauv daim ntawv ntawm lub kauj, uas yuav tsum tau txiav ntxiv rau hauv laminations rau transformer core daim ntawv thov, xws li qee yam khoom sab hauv hauv cov suab tso zis transformers.
Cov hlau siliconyog cov khoom siv sib nqus tseem ceeb tshaj plaws hauv kev siv hauv kev lag luam. Cov ntawv thov dav dav suav nrog cov generators, voltage relays lossis pulse transformers hauv kev lag luam tsheb thiab transformer
