Qhov txawv ntawm oriented silicon steel thiab non-oriented silicon steel:
1. Cov khoom sib txawv
Grain-oriented silicon steel: Grain-oriented silicon steel, tseem hu ua txias-dov transformer steel, yog ib qho tseem ceeb ferrosilicon alloy siv nyob rau hauv lub transformer (core) manufacturing kev lag luam.
Non-oriented silicon steel: Non-oriented silicon steel yog ferrosilicon alloy nrog cov ntsiab lus qis heev. Nws cov nplej yog random oriented nyob rau hauv deformed thiab annealed steel phaj.
2. Cov yam ntxwv sib txawv
Grain-oriented silicon steel: Lub magnetism ntawm grain-oriented silicon steel muaj zog directionality, nrog tus nqi qis tshaj hlau poob nyob rau hauv cov kev taw qhia dov, lub siab tshaj plaws magnetic permeability thiab siab sib nqus induction nqi nyob rau hauv ib tug tej yam magnetizing teb. Cov ntsiab lus ntawm silicon ntawm grain-oriented silicon steel yog kwv yees li 3 feem pua, thiab cov hlau yuav tsum muaj cov ntsiab lus oxide tsawg thiab yuav tsum muaj qee yam inhibitor (MnS, A1N).
Non-oriented silicon steel: Non-oriented silicon steel yog ferrosilicon alloy uas muaj 0.8 feem pua -4.8 feem pua silicon. Nws yog kub thiab txias dov rau hauv silicon steel los xij nrog lub thickness tsawg dua 1 hli. Ntxiv silicon tsub kom cov resistivity thiab siab tshaj plaws magnetic permeability ntawm hlau, txo coercive quab yuam, core poob (hlau poob) thiab sib nqus aging.
3. Cov txheej txheem ntau lawm
Grain-oriented silicon steel: Grain-oriented silicon steel yog smelted nyob rau hauv ib tug oxygen converter. Lub steel billet yog kub dov, normalized, txias dov, intermediate annealed thiab theem nrab txias dov mus rau lub tiav thickness, ces decarburized annealed thiab kub kub annealed, thiab thaum kawg coated nrog ib tug insulating txheej.
Non-oriented silicon steel: pre-desulfurization ntawm molten hlau, theem nrab desulfurization los ntawm kev ntxiv Ca0 ntxiv rau CaF: flux lossis tsis tshua muaj lub ntiaj teb cov ntsiab lus thiab calcium thaum lub tshuab converter. Lub boiling molten steel yog decarburized los ntawm lub tshuab nqus tsev kho mob thiab ces ntxiv desulfurized. Ferrosilicon nrog qis titanium thiab zirconium cov ntsiab lus raug xaiv rau alloying.
