Hluav taws xob hlautseem hu ua silicon steel ntawv. Nws txoj kev loj hlob muaj keeb kwm ntau tshaj 100 xyoo. Cold-dov hluav taws xob hlau muaj xws li taw qhia hluav taws xob hlau thiab tsis-oriented hluav taws xob hlau. Cov hlau tsis muaj hluav taws xob yog siv rau cov motors loj thiab nruab nrab, lub tshuab hluav taws xob, lub cev muaj zog hauv tsev thiab micromotors. Hlau cores rau ballasts thiab me me transformers, thiab lwm yam. Lub ntsiab sib nqus kev ua tau zoo yuav tsum tsis muaj tag nrho cov poob thiab siab sib nqus polarization. Tsawg tag nrho poob tuaj yeem txuag tau ntau lub zog thiab txuas ntxiv lub sijhawm ua haujlwm lub cev muaj zog. High magnetic polarization siv txhais tau hais tias muaj zog magnetizing muaj peev xwm, thiab qhov tam sim no ntawm cov tub ntxhais hlau yog txo, uas yog qis dua tag nrho cov poob thiab tooj liab. Tag nrho cov kev poob thiab sib nqus polarization tsis yog tsuas yog rau cov tshuaj muaj pes tsawg leeg, tab sis kuj rau lub koom haum sab hauv. Txhawm rau kom nkag siab zoo dua cov yam ntxwv ntawm cov khoom siv hluav taws xob tsis zoo, kev coj ua zoo dua thiab txhim kho cov khoom zoo.
Non-oriented hluav taws xob hlau
Kev sib xyaw ntawm txias-kuav los tiag uas tsis yog-oriented hluav taws xob hlau
Cov qib hluav taws xob tsis zoo yog cuam tshuam nrog W600, W800, thiab W1300, thiab steel phaj thickness yog 0.5 hli. Qhov ntsuas qhov nruab nrab ntawm peb cov khoom siv tshuaj muaj nyob rau hauv Table 1. Cov kws tshaj lij hluav taws xob yog cov kws tshaj lij hluav taws xob uas tsis tshua muaj roj carbon tsawg. Qhov sib txawv tseem ceeb ntawm peb yam yog cov ntsiab lus ntawm silicon thiab aluminium.
Hauv cov hlau tsis muaj hluav taws xob, silicon muaj cov txiaj ntsig ntawm kev ua kom muaj zog thiab txo qhov poob tag nrho, tab sis cov ntsiab lus tsis sib nqus txo saturation magnetization, uas tsis muaj txiaj ntsig rau nws tus kheej. Nyob rau tib lub sijhawm, cov ntsiab lus siab dhau lawm yuav ua rau cov hlau nkig thiab ua kom txias ua haujlwm nyuaj. Yog li, qhov txwv sab saud ntawm cov ntsiab lus silicon rau cov khoom siv hluav taws xob txias yog feem ntau nyob ib ncig ntawm 3.0%. Aluminium ua zoo ib yam li silicon. Cov teebmeem ntawm thaj tsam loj gamma theem, cov nplej ntxhib, muaj zog tiv taus, txo cov hlau nplaum anisotropy, txo tag nrho cov poob, txo qhov sib nqus polarization siv, thiab lub zog thiab hardness ntawm hlau tsis pom tseeb li cov silicon. Ob leeg silicon thiab txhuas tswj cov khoom siv kho tshuab thiab sib nqus ntawm cov hlau tsis muaj hluav taws xob los ntawm kev tswj cov nplej loj lossis cov qauv.
Nrog rau kev loj hlob ntawm high-ceev thiab miniaturized motors, kev ua tau zoo dua yuav tsum tau muab tso rau pem hauv ntej rau cov uas tsis yog-oriented hluav taws xob steel (xws li tsis muaj hlau poob ntawm high zaus thiab siab sib nqus induction zog, thiab lwm yam). Cov hlau tsis muaj hluav taws xob tsis tshua muaj siab yog cov pa roj carbon silicon mos sib nqus hlau nplaum thiab yog ib qho tseem ceeb thiab cov khoom siv tseem ceeb hauv lub zog, hluav taws xob thiab kev lag luam tub rog. Raws li kev txheeb cais, tag nrho cov khoom siv hluav taws xob hauv ntiaj teb hauv xyoo 2000 yog 6.714 lab tons, thiab los ntawm 2005 nws tau tshaj 8 lab tons. Kev lag luam kev lag luam hauv tsev tau tshaj li 3 lab tons. Ntawm lawv, cov hlau tsis muaj hluav taws xob yog cov khoom siv tseem ceeb ntawm cov rotors ntawm lub cev muaj zog thiab cov tshuab hluav taws xob uas ua haujlwm nyob rau hauv rotating magnetic teb thiab xav tau cov khoom sib nqus zoo thiab cov txheej txheem.
Cov kev hloov pauv ntawm hardness ntawm cov hluav taws xob tsis-oriented steel yog raws li qhov kev hloov pauv ntawm lub zog tensile, thiab lub hardness qhia txog kev xuas nrig ntaus ntawm cov hlau. Qhov siab dua cov ntsiab lus ntawm silicon, qhov hardness ntawm cov hlau ntau dua, thiab kev ua haujlwm xuas nrig yuav txo qis. Txawm li cas los xij, yog tias lub hardness ntawm cov hlau tsis dhau, qhov burrs ntawm cov punching yuav nce, thiab qhov punching loj yuav tsis raug. Qhov tsim nyog hardness ntawm hlau nrog zoo xuas nrig ntaus yog 130HV ~ 180HV.
