Dab tsi yog Oriented Silicon Steel Thiab Non Oriented Silicon Steel?
Jun 07, 2023
01. Cov khoom sib txawv:
Oriented silicon steel: Oriented silicon steel, tseem hu ua txias dov transformer steel, yog ib qho tseem ceeb ferrosilicon alloy siv nyob rau hauv lub transformer (hlau core) kev lag luam.
Non-oriented silicon steel: Tsis yog taw qhia silicon steel yog silicon hlau alloy uas muaj cov pa roj carbon tsawg heev, thiab nws cov nplej yog qhov tsis sib xws hauv cov hlau phaj tom qab deformation thiab annealing.
02. Cov yam ntxwv sib txawv:
Oriented silicon steel: Cov khoom sib nqus ntawm oriented silicon steel muaj cov kev taw qhia muaj zog, nrog rau cov hlau tsis tshua muaj nqi, siab tshaj magnetic permeability, thiab siab sib nqus induction tus nqi nyob rau hauv dov kev taw qhia nyob rau hauv ib tug tej yam magnetization teb. Cov ntsiab lus ntawm silicon ntawm oriented silicon steel yog kwv yees li 3 feem pua, thiab nws yuav tsum muaj cov ntsiab lus qis ntawm oxide inclusions hauv cov hlau, nrog rau muaj qee yam inhibitors (MnS, A1N).
Non-oriented silicon steel: Non oriented silicon steel yog silicon hlau alloy nrog cov ntsiab lus silicon ntawm 0.8 feem pua -4.8 feem pua, uas yog kub thiab txias dov rau hauv silicon steel los xij nrog lub thickness ntawm tsawg dua 1mm. Ntxiv silicon tuaj yeem ua rau muaj kev tiv thaiv thiab siab tshaj plaws sib nqus permeability ntawm hlau, txo kev coercivity, core poob (hlau poob), thiab sib nqus aging.
03. Cov txheej txheem ntau lawm:
Oriented silicon steel: Lub oriented silicon steel yog melted nyob rau hauv ib tug oxygen converter, thiab lub steel billet yog kub dov, normalized, txias-dov, annealed nyob rau hauv nruab nrab, thiab txias-dov ob zaug los ua ib tug tiav thickness. Tom qab ntawd, nws dhau mus decarburization annealing thiab kub-kub annealing, thiab thaum kawg coated nrog ib txheej rwb thaiv tsev.
Non-oriented silicon steel: kub hlau ua ntej desulfurization, theem nrab desulfurization los ntawm kev ntxiv Ca0 ntxiv rau CaF: flux los yog tsawg lub ntiaj teb cov ntsiab lus thiab calcium thaum lub sij hawm converter tshuab. Boiling molten steel yog decarburized los ntawm kev kho lub tshuab nqus tsev ua ntej desulfurization ntxiv. Xaiv ferrosilicon uas tsis tshua muaj titanium thiab zirconium cov ntsiab lus rau alloying.
Cold-dov silicon steel ntawv: Grain oriented thiab non oriented steel strips.
Grain oriented txias dov strips feem ntau yog siv los ua hlau cores rau motors lossis vuam transformers; Cov nplej taw qhia txias dov sawb yog siv los ua cov tub ntxhais hlau rau lub zog transformers, pulse transformers, thiab magnetic amplifiers. Cold dov oriented nyias silicon steel sawb yog tsim los ntawm {{0}}}.30 los yog 0.35mm tuab oriented silicon steel sawb, uas yog ces pickled, txias dov, thiab annealed.
Cov ntawv txias txias uas tsis yog kev taw qhia silicon steel ntawv yog dov rau hauv coils nrog lub thickness ntawm kwv yees li 2.3 hli los ntawm steel billets los yog nruam casting billets. Txias dov hluav taws xob steel sawb muaj cov yam ntxwv ntawm qhov chaw tiaj tus, cov tuab tuab, siab sib npaug coefficient, kev ua haujlwm zoo punching, thiab siab dua hlau nplaum induction thiab qis hlau poob piv rau kub dov hluav taws xob steel sawb.
Siv cov hlua txias es tsis txhob kub dov los tsim cov motors lossis transformers tuaj yeem txo lawv qhov hnyav thiab ntim los ntawm 0 feem pua -25 feem pua . Yog tias siv cov kab mob khaub thuas-kuav los tiag, kev ua haujlwm zoo dua. Siv nws es tsis txhob kub-kuav los tiag strip los yog qis-qib txias-dov strip tuaj yeem txo cov hluav taws xob siv hluav taws xob ntawm lub tshuab hluav taws xob los ntawm 45 feem pua -50 feem pua, thiab kev ua haujlwm ntawm lub tshuab hluav taws xob muaj kev ntseeg siab dua.
Lub ntsiab lus ntawm cov ntawv uas tsis yog-oriented silicon steel:
Non-oriented silicon steel daim ntawv yog ib daim ntawv silicon steel uas tsim ib qho tsis oriented deformation kev ntxhib los mos crystalline qauv raws li cov txheej txheem ntau lawm.
Oriented silicon steel ntawv:
Thaum ntxov xyoo 1920, Williams tau tshawb fawb txog ib qho crystals hauv ferrosilicon thiab pom tias um=140000 nyob rau hauv {100} kev taw qhia ntawm qhov yooj yim magnetization axis. Nws ntseeg hais tias nyob rau hauv ntau daim hlau, kev ua tau zoo heev yuav tsum tau ua tiav hauv {100} axis.
Xyoo 1926, tus kws tshawb fawb Nyij Pooj Bendo Mao tau tshawb pom tias cov kev taw qhia crystallization ntawm cov hlau yog qhov yooj yim tshaj plaws magnetized, los yog cov kev taw qhia ntawm cov qoob loo cov npoo yog cov kev taw qhia yooj yim tshaj plaws magnetized.
Xyoo 1934, NP Goss, ib tug neeg Amelikas, tau ua tiav cov ntawv qhia txog silicon steel hauv chav kuaj. Nws siv kev sib xyaw ua ke ntawm kev ua kom txias txias thiab kub kub kho los npaj cov nplej hauv silicon steel nplooj ntawv kom zoo raws li cov kev taw qhia dov, muaj cov hlau nplaum zoo heev.
Xyoo 1935, Goss luam tawm ib tsab xov xwm hauv TransAmer. Soc. Hlau, qhia txog nws cov kev tshawb fawb tshawb pom, thiab tau thov rau British patent (No. 442211).
Nyob rau hauv tib lub xyoo, Armco Company nyob rau hauv lub tebchaws United States pib muaj kev lag luam ntawm txias-dov oriented silicon steel nplooj ntawv. Nyob rau xyoo 1940, Armco thiab Allegheny tau tsim cov ntawv zoo tshaj plaws ntawm silicon steel ntawv rau transformers. Lub npe ntawm Armco yog Tran-cor (hu ua Hipersil los ntawm Westinghouse); Allegeny lub hom yog Silicon (hu ua Corosil los ntawm GE).
Xyoo 1953, Nyiv tau tsim cov ntawv txias-khoov taw qhia silicon steel nplooj ntawv.
Xyoo 1958, Nyiv tau qhia txog cov cuab yeej siv thev naus laus zis ntawm Armco Company thiab pib tsim cov khoom lag luam ntawm cov ntawv txias-khoov taw qhia silicon steel nplooj ntawv. Raws li qhov no, kev txhim kho tas mus li tau ua, nqa qhov kev ua tau zoo ntawm cov ntawv txias-dov silicon steel hauv Nyij Pooj mus rau lub ntiaj teb qib siab tshaj plaws.
Single oriented silicon steel nplooj ntawv muaj cov hlau nplaum tsis tshua muaj hluav taws xob perpendicular mus rau qhov kev taw qhia dov. Txhawm rau kov yeej qhov tsis zoo no, lub tuam txhab German lub tshuab nqus tsev melting tau tsim ob qho kev taw qhia silicon steel nplooj ntawv hauv xyoo 1940.
Xyoo 1957, GE thiab Westinghouse hauv Tebchaws Meskas yuav luag ib txhij tsim dual taw qhia silicon steel nplooj ntawv, thiab hauv xyoo 1960, Kawasaki thiab Yamagata cov chaw tsim khoom hauv Nyij Pooj kuj tau tsim dual taw qhia silicon steel nplooj ntawv. Nws cov khoom sib nqus nyob rau hauv cov kev taw qhia dov thiab ntsug kev taw qhia yog zoo ib yam li cov nyob rau hauv lub dov kev taw qhia ntawm ib tug oriented silicon steel los xij. Cov nplej ntawm cov ntawv silicon steel no nthuav tawm cov qauv cubic. (ID ntawm Steel Rolling House: zhangzhija)
Xyoo 1968, Nippon Steel Hoobkas hauv Nyij Pooj tau pib muaj kev tsim cov hlau nplaum sib nqus zoo siab qhia cov ntawv silicon steel. Nws lub npe lag luam yog "OrientcoreHi-B", luv luv li "Hi-B"; Nyob rau hauv 1972, ib tug loj lattice siab conductivity oriented silicon steel ntawv tau tsim; Nyob rau hauv 1981, ib tug me me lattice high conductivity oriented silicon steel ntawv tau tsim ntxiv; Nyob rau hauv 1982, Nyiv pib tsim cov high conductivity oriented silicon steel nplooj ntawv kho nrog nto laser irradiation (ZDKH), ntxiv txo hlau poob.
Xyoo 1988, Nyiv tau tsim cov ntawv sib nqus hlau nplaum silicon hlau siv cov txheej txheem los ua cov txheej txheem kev ntxhov siab micro (ADMH). Txoj kev loj hlob ntawm kev taw qhia silicon steel los ntawm Nippon Steel Company hauv Nyiv. Nyob rau xyoo 1950, ntau lub teb chaws tau ntsuas qhov ua tau zoo ntawm ib qho kev taw qhia silicon steel los xij · Cov kev hloov pauv zoo ntawm cov ntawv qhia thiab cov ntawv tsis yog silicon steel hauv Nyij Pooj xyoo 1955 thiab 1975. Qhov kev poob qis ntawm cov tub ntxhais hlau thiab steel hlau poob ntawm 1880 thiab 1970.
