Thawj theem pib rau silicon steel coils thiab nplooj ntawv tso siab rau kev ua kom zoo thiab kub dov; Cov kauj ruam no txiav txim siab cov khoom siv purity thiab lub hauv paus microstructure, ua cov txheej txheem tseem ceeb rau kev ua haujlwm ntawm electromagnetic. Kev tsim khoom pib nrog siab -zoo npua hlau thiab cov khoom seem hlau ua raw khoom. Cov impurities raug tshem tawm los ntawm kev ntxhib ntxhib los mos hauv qhov hloov pauv lossis hluav taws xob arc rauv, ua raws li kev hloov pauv ntawm cov ntsiab lus alloying -xws li silicon, manganese, thiab carbon- nyob rau hauv qhov cub refining. Silicon cov ntsiab lus yog nruj me ntsis tswj nyob rau hauv tus txheej txheem ntau yam, thaum muaj teeb meem impurities xws li sulfur, phosphorus, thiab carbon yog txo kom txhob muaj kev phiv los ntawm magnetic permeability thiab hlau poob. Cov hlau uas ua kom zoo zoo yog cam khwb cia rau hauv cov pob zeb, rov ua kom qhov kub thiab txias, thiab muab tso rau hauv qhov kub - dov zeb. Los ntawm ntau qhov kev sib txuas ntawm cov dov tsis tu ncua, cov ntawv tuab tuab tau hloov mus rau hauv kub -rolled strips ntawm cov tuab tuab, cov txheej txheem uas ua kom zoo zoo hauv cov nplej thiab densifies microstructure. Tom qab- dov, cov strips tau ua kom txias, coiling, thiab qib kom tshem tawm cov kev ntxhov siab ntawm cov dov, uas ua rau kub -rolled silicon steel substrate nrog cov khoom ruaj khov- tso lub hauv paus ruaj khov rau qhov txias tom ntej - dov thiab ua tiav.
Precision txias dov thiab annealing yog cov txheej txheem tseem ceeb rau shaping silicon steel thiab optimizing nws electromagnetic kev ua tau zoo; lawv yog cov txheej txheem thev naus laus zis tseem ceeb uas paub qhov txawv siab -kawg hluav taws xob silicon steel los ntawm cov hlau zoo tib yam. Qhov kub- dov substrate ua ntej undergoes pickling kom huv si tshem tawm cov nplais thiab xeb, ua kom huv si. Tom qab ntawd nws nkag mus rau qhov siab -precision txias- dov zeb rau ntau- hla kev txo qis, qhov twg nws yog dov rau tus qauv ultra- nyias specifications- xws li 0.1 hli, 0.27 hli, 0.35 hli, los yog 0.5 hli - raws li cov khoom xav tau. Thickness tolerances thiab nto flatness yog nruj me ntsis tswj kom ua tau raws li qhov xav tau ntawm kev ua tiav tom ntej. Tom qab txias dov, cov hlau khaws cov kev ntxhov siab tseem ceeb thiab raug kev txom nyem los ntawm cov qoob loo loj heev; Cov yam ntxwv los ntawm siab hardness thiab brittleness, nws tsis tuaj yeem siv ncaj qha thiab yuav tsum tau ua kom siab tshaj -kub annealing. Tsis yog-qhia silicon steel siv cov txheej txheem txuas ntxiv txuas ntxiv txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhuam cov pob zeb Hauv qhov sib piv, cov nplej- taw qhia silicon hlau tau dhau los ua ntau- theem siab- kub annealing thiab theem nrab recrystallization txheej txheem; cov no yuam cov nplej mus rau hauv ib qho kev sib raug zoo raws li qhov kev taw qhia dov, ua tiav unidirectional ultra-cov tub ntxhais poob qis thiab ultra-siab sib nqus permeability, yog li qhib tag nrho cov khoom siv hluav taws xob zoo tshaj plaws.
Cov txheej txheem tom qab-xws li txheej, xov / txiav, thiab kev soj ntsuam zaum kawg- txiav txim siab cov silicon steel kev nyab xeeb kev ua haujlwm, kev ua haujlwm sib raug zoo, thiab qhov zoo tshaj plaws. Tom qab annealing, steel sawb yuav tsum tau ntxuav kom tshem tawm cov roj thiab oxide residues; ib qho tshwj xeeb inorganic insulating txheej yog tom qab ntawd siv uniformly ntawm cov menyuam txheej thiab kho ntawm qhov kub thiab txias. Qhov no tsim cov txheej txheem tiv thaiv uas muaj zog adhesion, tshav kub thiab hnav tsis kam, thiab zoo heev rwb thaiv tsev, zoo tiv thaiv eddy tam sim no luv circuits ntawm laminations. Tom qab txheej txheej thiab kho, lub sawb tau nce qib thiab ncaj qha los kho qhov tsis xws luag xws li warping lossis waviness, kom ntseeg tau tias lub tiaj tus, zoo ib yam. Thaum kawg, cov khoom raug ua tiav - ntawm kev txiav, txiav - mus rau -ntev shearing, thiab coiling - rau hauv cov qauv silicon steel coils lossis cov ntawv raws li cov neeg siv khoom tshwj xeeb. Tag nrho cov khoom tiav tau txais qhov seem rov- kev tshuaj xyuas, kev kuaj xyuas qhov zoo, kev ua haujlwm ntawm electromagnetic, thiab kuaj cov cuab yeej cuab yeej; tsuas yog tom qab ua tau raws li tag nrho cov qauv yog lawv ntim thiab warehoused. Qhov kev tswj xyuas zoo no ua kom cov khoom tiav ua tiav raws li kev tsim khoom thiab kev ua haujlwm rau ntau lub cav, transformers, thiab cov khoom siv hluav taws xob precision.
