Qhov kev xaiv ntawm cov khoom siv Lamination yog ib qho kev txiav txim siab tseem ceeb tshaj plaws hauv cov kev xaiv muaj zog Laminated steel thiab silicon steel. Cov ntsiab lus Silicon siab (2-5.5 wt% silicon) thiab nyias phaj (0.2-0.65 mm) steel yog mos sib nqus rau lub cev sib nqus cov ntaub ntawv thiab rotors. Qhov kev sib ntxiv ntawm silicon rau cov hlau ua kom qis dua cov hlau ua haujlwm thiab ntau dua resisticity, thiab kev txo qis hauv nyias phaj tuab ua rau qis dua Eddy kev poob qis.
Txias zog dov laminated hlau yog ib qho ntawm cov nqi siv qis tshaj plaws hauv huab hwm coj ntau lawm thiab yog ib qho ntawm cov nyiam tshaj plaws alloys. Cov khoom siv tau yooj yim rau stamp thiab tsim tawm tsawg dua hnav ntawm cov khoom siv stamping dua li lwm cov ntaub ntawv. Lub cev muaj zog manufacturers hais lub cev muaj zog laminated hlau nrog cov yeeb yaj kiab oxinide uas nce interfayer tsis kam, ua rau nws piv rau cov hlau uas silicon. Qhov sib txawv ntawm lub cev muaj zog laminated steel thiab txias-rolled steel yog nyob rau hauv cov steel muaj pes tsawg leeg thiab ua kev txhim kho (xws li annealing).
Cov hlau cov hlau, tseem muaj cov hluav taws xob ua hluav taws xob, yog cov roj carbon hlau tsawg dua nrog cov pa roj cua me me ntxiv los txo cov qauv eddy tam sim no poob rau hauv cov tub ntxhais. Silicon tiv thaiv cov stator thiab cov tshuab pauv hluav taws xob thiab txo cov hysteresis ntawm cov khoom, lub sijhawm ntawm thawj tiam thiab nws tag nrho tiam. Thaum cov khaub thuas dov thiab kom zoo taw qhia, cov khoom siv tau npaj rau cov ntawv thov kev sib tw lamination. Feem ntau, silicon cov tawv nqaij laminates yog insulated ntawm ob sab thiab muab cov khoom sib ntxiv los txo edloy tau muaj kev cuam tshuam loj rau lub neej ntawm cov cuab yeej stamping thiab tuag.
Silicon steel yog muaj nyob rau hauv ntau cov thicknesses thiab qib, nrog rau hom zoo tshaj nyob ntawm cov hlau uas tsis muaj nqis nyob rau hauv watts rau ib kilogram. Txhua qib thiab tuab cuam tshuam rau cov rwb thaiv tsev saum npoo av ntawm cov alloy, lub neej ntawm cov twj stamping, thiab lub neej ntawm tuag. Zoo li txias-dov laminated steel, annealing yuav pab ntxiv dag zog cov txheej txheem silicon, thiab cov ntawv qhia tawm-stamping exsim, yog li txo kev ntxhov siab. Ua raws li hom silicon steel siv, kev kho ntxiv ntawm cov khoom siv yog yuav tsum tau txuas ntxiv daws kev ntxhov siab ntxiv.
Cov txheej txheem txias-dov steel tsim ntxiv cov txiaj ntsig tseem ceeb rau cov khoom siv raw. Txias-dov lub tsev kawm tiav yog ua nyob rau ntawm lossis me ntsis saum chav chav kub, ua rau nplej ntawm cov hlau uas muaj ntev elongated nyob rau hauv cov kev coj dov. Qhov kev siv siab siab rau cov khoom siv thaum lub sijhawm ua haujlwm tsim kho cov hlau txias, ua rau muaj qhov chaw du thiab muaj tseeb thiab zoo ib yam. Cov txheej txheem txias no tseem ua rau muaj dab tsi hu ua "strain hardening", uas tuaj yeem piv rau cov qib tsis yog siv tag nrho, ib nrab plaub hau thiab tawv tawv. Rolling muaj nyob rau hauv ntau yam duab, suav nrog puag ncig cov duab, xwmfab thiab tiaj tus qhab nia, thiab cov nqi qis dua, thiab nws tus nqi qis ntxiv kom nws ua rau tus caj qaum ntawm txhua yam kev tsim khoom.
Tusrotorthiabtus ciNyob rau hauv ib lub cev muaj zog yog tsim los ntawm ntau pua laminated thiab koom nrog edriving ntawm ob tog Feem ntau, cov hluav taws xob hluav taws xob yog riveted los yog welded kom ntseeg tau cov neeg kho tshuab zog ntawm lub laminate. Kev puas tsuaj rau cov txheej txheem rwb thaiv tsev los ntawm cov txheej txheem vuam tuaj yeem ua rau muaj kev ntxhov siab, thiab kev hloov pauv ntawm cov tshuab muaj zog thiab cov khoom sib nqus.
