Silicon steel ntawv
Silicon hlaufeem ntau hu ua silicon steel ntawv lossis silicon steel ntawv. Nws yog ib qho tseem ceeb uas tsis muaj cov pa roj carbon monoxide ferrosilicon mos magnetic alloy hauv lub zog, hluav taws xob thiab kev lag luam tub rog. Nws kuj yog cov khoom siv hlau ua haujlwm nrog cov khoom siv loj tshaj plaws. Nws cov zis tso nyiaj txog li 1% ntawm lub ntiaj teb cov khoom siv hlau. Nws yog ferrosilicon alloy nrog cov ntsiab lus silicon ntawm 0.8%-4.8%, uas yog kub thiab txias dov rau hauv cov ntawv silicon steel nrog lub thickness tsawg dua 1 hli. · Ntxiv silicon tuaj yeem ua rau kom muaj zog thiab siab tshaj plaws permeability ntawm hlau, txo kev coercivity, core poob (hlau poob) thiab sib nqus aging. Nws yog tsuas yog siv los ua lub hauv paus ntawm ntau yam motors, generators thiab transformers.
Kev faib tawm ntawm Silicon steel phaj
Silicon steel los xij tuaj yeem muab faib ua silicon qis thiab siab silicon raws li lawv cov ntsiab lus silicon.
1. Tsawg silicon wafer
Tsawg silicon wafers muaj tsawg dua 2.8% silicon, uas muaj qee yam kev siv zog thiab feem ntau yog siv los tsim cov motors, feem ntau hu ua silicon steel nplooj ntawv rau motors;
2. High silicon wafer
Cov ntsiab lus ntawm silicon siab silicon wafer yog 2.8% -4.8%. Nws muaj cov khoom sib nqus zoo tab sis kuj yog nkig. Nws yog tsuas yog siv los ua transformer cores, feem ntau hu ua transformer silicon steel nplooj ntawv. Tsis muaj kev txwv nruj ntawm ob qho tib si hauv kev siv tiag tiag, thiab high-silicon wafers feem ntau siv los tsim cov motors loj.
Classified los ntawm cov txheej txheem ntau lawm
tuaj yeem muab faib ua ob hom: kub dov thiab txias dov
Txias dov tuaj yeem muab faib ua ob hom: tsis yog-oriented grain thiab grain orientation: cov ntawv txias-dov muaj cov tuab tuab, zoo nto zoo, thiab cov khoom sib nqus zoo. Yog li ntawd, nrog txoj kev loj hlob ntawm kev lag luam, cov ntaub ntawv kub-kuav los tiag muaj lub siab nyiam los hloov cov ntawv txias-dov.
Cold dov silicon steel ntawv
Cold-rolled silicon steel ntawv yog muab faib ua ob hom steel strips: non-oriented grain thiab grain oriented.
Non-oriented grain txias-dov strips feem ntau yog siv los ua hlau cores rau motors lossis vuam transformers; grain-oriented txias-dov strips yog siv los ua hlau cores rau lub hwj chim transformers, pulse transformers, magnetic amplifiers, thiab lwm yam mm tuab oriented silicon steel sawb, uas yog ces pickled, txias dov thiab annealed.
Cov ntawv txias-kuav los tiag uas tsis yog-oriented silicon steel ntawv yog cov kub-kuav los tiag steel billet los yog nruam casting billet rau hauv ib lub kauj nrog ib tug tuab ntawm txog 2.3 hli. 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 lwm yam, thiab muaj cov hlau nplaum ntau dua thiab cov hlau tsis zoo dua li kub-dov hluav taws xob steel sawb.
Siv cov hlua txias es tsis txhob kub dov sawb los tsim cov motors lossis transformers, nws qhov hnyav thiab ntim tuaj yeem txo tau los ntawm 0%-25%. Yog tias siv daim kab xev txias-kuav los tiag, qhov kev ua tau zoo dua. Siv nws es tsis txhob kub-dov los yog qis-qib txias-kuav los tiag daim kab xev tuaj yeem txo transformer fais fab noj los ntawm 45%-50%, thiab transformer kev ua tau zoo dua.
Lub ntsiab lus ntawm non-oriented silicon steel ntawv
Non-oriented silicon steel daim ntawv yog ib daim ntawv silicon steel nrog ib tug uas tsis yog-oriented deformation kev ntxhib los mos crystalline qauv tsim raws li ib tug tej yam ntau lawm txheej txheem.
Oriented silicon steel ntawv
Thaum ntxov xyoo 1920, William (Williams) tau kawm ib qho crystals hauv ferrosilicon thiab pom tias um=1400000 nyob rau hauv {100} kev taw qhia ntawm qhov yooj yim axis ntawm magnetization. Nws ntseeg tias nws yuav tsum yog qhov zoo tshaj plaws nyob rau hauv {100} axis nyob rau hauv lub phaj polycrystalline. Kev ua tau zoo.
Xyoo 1926, Japanese Honda Mao tau tshawb pom tias cov crystallographic kev taw qhia ntawm cov hlau yog qhov yooj yim tshaj plaws rau magnetize, los yog cov kev taw qhia ntawm cov pob zeb siv lead ua lub voos xwmfab ntug yog qhov yooj yim tshaj plaws rau magnetize kev taw qhia.
Xyoo 1934, Asmeskas NPGoss tau ua tiav cov ntawv qhia cov ntawv silicon steel hauv chav kuaj. Nws siv kev sib xyaw ua ke ntawm kev ua kom txias txias thiab kub kub kho kom sov ua kom cov hmoov nplej siv lead ua hauv cov ntawv silicon steel txheej txheej txheej txheem raws li cov kev taw qhia dov. Sib nqus.
Xyoo 1935, Goss luam tawm ib tsab xov xwm hauv "TransAmer.Soc.Metals", qhia txog cov txiaj ntsig kev tshawb fawb, thiab thov rau British patent (No. 442211).
Nyob rau hauv tib lub xyoo, Armco ntawm 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 zoo silicon steel ntawv rau transformers. Armco lub npe yog Tran-cor (Westinghouse hu ua Hipersil); Allegeny lub npe yog Silicon (GE tuam txhab hu ua Corosil).
Xyoo 1953, Nyiv tau sim tsim cov ntawv txias-kuav los tiag silicon steel los xij.
Xyoo 1958, Nyiv tau qhia txog Armco's patented thev naus laus zis los pib kev lag luam ntawm cov ntawv txias-kuav los tiag silicon steel los xij, thiab ntawm lub hauv paus no, kev txhim kho txuas ntxiv tau ua rau kev ua haujlwm ntawm Japanese txias-dov silicon steel nplooj ntawv mus txog qib siab tshaj plaws hauv ntiaj teb.
Cov ntawv ib leeg-oriented silicon steel ntawv muaj tsawg sib nqus permeability nyob rau hauv cov kev taw qhia perpendicular mus rau dov kev taw qhia. Yuav kom kov yeej qhov kev tsis txaus no, lub tuam txhab German lub tshuab nqus tsev melting tau tsim dual-oriented silicon steel ntawv hauv xyoo 1940.
Xyoo 1957, GE thiab Westinghouse hauv Tebchaws Meskas kuj tau tsim dual-oriented silicon steel nplooj ntawv yuav luag ib txhij. Nyob rau xyoo 1960, Kawasaki thiab Yawata cov chaw tsim khoom hauv Nyij Pooj kuj tau ua tiav kev tsim dual-oriented silicon steel nplooj ntawv. Nws cov khoom sib nqus nyob rau hauv cov kev taw qhia dov thiab cov kev taw qhia ntsug yog zoo ib yam li cov ntawm ib leeg-oriented silicon steel ntawv nyob rau hauv cov kev taw qhia dov. Cov pob zeb siv lead ua ntawm no silicon steel ntawv yog cubic.
Xyoo 1968, Nyiv Nippon Steel Plant tau pib ua lag luam tsim cov ntawv siab-permeability oriented silicon steel los xij. Nws lub npe lag luam yog "Orientcore Hi-B", lossis "Hi-B" luv luv; Nyob rau hauv 1972, loj-lattice high-permeability oriented silicon steel yog tsim nyob rau hauv 1981, ib tug me me-lattice high-permeability oriented silicon steel ntawv tau tsim ntxiv; Nyob rau hauv 1982, Nyiv pib tsim kho deg laser irradiation (ZDKH) high-permeability oriented silicon steel ntawv, uas ntxiv txo hlau poob.
Nyob rau hauv 1988, Nyiv tau tsim ib qho high-permeability oriented silicon steel ntawv siv cov cuab yeej siv los tsim cov txheej txheem micro-stress (ADMH). Saib ntawm txoj kev loj hlob ntawm grain-oriented silicon steel ntawv los ntawm Nippon Steel Corporation. Hauv xyoo 1950, kev ua haujlwm ntawm ib leeg-taw qhia silicon steel nplooj ntawv hauv ntau lub tebchaws. · Nyob nruab nrab ntawm 1955 thiab 1975, qhov zoo ntawm oriented silicon steel ntawv thiab non-oriented silicon steel ntawv nyob rau hauv Nyiv hloov. Los ntawm 1880 txog 1970, qhov poob qis ntawm cov tub ntxhais hlau ntawv hlau poob.
