Dab tsi yog cov khoom xyaw ntawm Non Oriented Silicon Steel?

Cov ntsiab lus ntawm silicon, aluminium thiab manganese nyob rau hauv steel yog tswj nyob rau hauv ib tug tej yam ntau yam raws li txoj cai, thiab cov ntsiab lus ntawm carbon, sulfur, nitrogen thiab oxygen yog tsawg li sai tau. Nyob ntawm qib, cov ntsiab lus xav tau rau cov ntsiab lus no kuj txawv. Aluminium tsub kom lub zog thiab hardness ntawm hluav taws xob steels thiab txo ductility. Txawm li cas los xij, cov nyhuv ntawm txhuas ntawm kev txo cov ductility tsis yog hais tau zoo li silicon, thiab cov nyhuv zoo ib yam li silicon. Yog li ntawd, nrog kev nce qib, cov ntsiab lus silicon nce mus txog 3 feem pua ​​​​tsis muaj kev hloov pauv, thiab cov ntsiab lus txhuas tuaj yeem maj mam nce mus rau 1 feem pua. Cov ntsiab lus dav dav ntawm aluminium yog 0.3 feem pua ​​~ 0.6 feem pua ​​. Raws li qib nce, cov ntsiab lus carbon, sulfur thiab manganese raug txo kom tsawg. Qib siab impurity cov ntsiab lus yog: S<0.002%, C<0.003%, N2<0.002%, O2<0.002%, annealing does not need to be decarburized, preventing the formation of internal oxide layer and internal nitriding layer. In addition, Ti<0.005% and Zr<0.002% are required to prevent the formation of fine TiN, ZrN and TiC, which hinder grain growth.
