Txoj kev loj hlob zeem muag ntawm cov kev lag luam uas tsis yog-oriented hluav taws xob steel yog zoo heev, vim hais tias nws coj ntau cov txiaj ntsig rau kev lag luam thaum siv, yog li nws tau nyiam los ntawm cov neeg siv khoom. Yuav kom txhua leej txhua tus paub txog nws, peb yuav los tom ntej no Qhia peb txog qhov zoo ntawmnon-oriented hluav taws xob steel? Kuv vam tias nws tuaj yeem pab tau ntau tus neeg.
Niaj hnub no, tseem muaj ntau tus neeg uas tsis to taub qee cov ntaub ntawv tseem ceeb ntawm cov khoom siv hluav taws xob tsis zoo, yog li ua cov chaw tsim khoom, peb yuav tsum piav qhia luv luv. Qhov tseeb, tus yuam sij rau qhov tsis yog-oriented hluav taws xob hlau yog kev siv cov recrystallization theem nrab. Txhawm rau kom ua tiav cov txheej txheem recrystallization, feem ntau nws yog qhov yuav tsum tau ntxiv cov hmoov nplej loj hlob inhibitors, xws li MnS, rau qhov sib tov. Cov qoob loo loj hlob inhibitor yuav tsum tau tawg nyob rau hauv cov hlau matrix nyob rau hauv daim ntawv ntawm doping, tshwj xeeb tshaj yog thaum theem nrab recrystallization tshwm sim, nws muaj peev xwm tiv thaiv tau qhov kev loj hlob ntawm lub matrix siv lead ua, thiab tej zaum yuav tsim nyog nyob rau tib lub sij hawm. Nws yog yooj yim tshem tawm thaum lub sij hawm kawg high-temperature melting txheej txheem, yog li cov khoom sib nqus ntawm cov khoom tsis deteriorate. Los yog nyob rau hauv theem nrab recrystallization, lub orientation nuclei ntawm theem nrab grain loj hlob tsuas yog cia siab rau qhov tsim nyog txias dov txheej txheem thiab recrystallization annealing. Txij li thaum lub sij hawm transformation ua rau lub grain orientation, nws yog ib qho tseem ceeb kom tswj tau ib theem thaum tshav kub kub kho. Nyob rau hauv luv luv, tsis yog-oriented hluav taws xob steel yog ib hom hlau-raws li hlau nplaum hlau nrog ib tug silicon ntsiab lus ntawm 0.5-6.5%. Txij li thaum nws cov txheej txheem cej luam tsis yog kev taw qhia, koj yuav pom tias nws qhov kev ua tau zoo yog qhov zoo ib yam ntawm txhua qhov kev qhia. Nws yog tsuas yog siv los ua lub tshuab tig, xws li loj, nruab nrab, me me, thiab ntau yam micromotors. Tsis tas li ntawd, cov hlau tsis muaj hluav taws xob kuj tseem siv rau hauv cov motors zoo li qub uas tsis tas yuav muaj qhov sib nqus sib nqus induction, xws li cov cores ntawm cov transformers me me.
Tsis yog-oriented hluav taws xob hlau yog ib yam khoom uas muaj txiaj ntsig zoo los yog ob qho tib si ntawm nws cov khoom. Piv txwv li, qee qhov txhuas ua haujlwm zoo ib yam li silicon. Txhuas tuaj yeem ua kom muaj zog, txo cov cheeb tsam austenite, thiab txhawb kev loj hlob ntawm cov nplej, yog li nws muaj qee yam txiaj ntsig zoo. Txawm li cas los xij, kev ua haujlwm ntawm cov hlau tsis muaj hluav taws xob yog cuam tshuam los ntawm cov ntsiab lus nitrogen hauv silicon steel. Aluminium thiab nitrogen yooj yim tsim AlN precipitates, uas txo cov khoom sib nqus ntawm silicon steel los xij. Thaum cov nplej loj ntawm cov precipitated AlN tsawg dua 0.5μm, lawv yuav kho cov ciam teb nplej thiab koj yuav pom cov nplej loj hlob raug cuam tshuam, yog li ua rau cov hlau poob. Txawm li cas los xij, thaum qhov loj ntawm cov nag lossis daus AlN loj dua 1 μm, nws cov txiaj ntsig pinning ntawm cov ciam teb yog me ntsis, yog li nws muaj me ntsis cuam tshuam rau cov khoom sib nqus ntawm cov qauv. Cov ntsiab lus phosphorus tuaj yeem txhim kho cov khoom sib nqus ntawm ferrosilicon alloys. Phosphorus ua cov hlau phosphide ntawm cov ciam teb, uas tuaj yeem txhim kho kev ua haujlwm ntawm silicon steel. Kev sib cais ntawm phosphorus ntawm cov ciam teb yuav cuam tshuam lub nucleation thiab kev loj hlob ntawm unfavorably oriented recrystallized nplej thiab nce qhov sib nqus induction siv. Nyob rau tib lub sijhawm, phosphorus hauv cov hlau tsis muaj hluav taws xob yuav ua rau lub zog ntawm silicon steel thiab txo cov hlau tsis zoo. Tau kawg, peb lub tuam txhab cov khoom tseem tuaj yeem ua tau raws li cov kev xav tau no. Peb zoo siab tos txais los ntawm no los tsim kom muaj kev sib koom tes ntev nrog cov phooj ywg los ntawm thoob plaws lub tebchaws. Tom qab tag nrho, nws yog nto moo heev nyob rau hauv no kev lag luam, nrog rau tus nqi tsim nyog thiab guaranteed zoo.
Tom qab cov lus qhia saum toj no, peb muaj kev nkag siab ntxiv txog qhov zoo ntawm cov hlau tsis muaj zog. Koj yuav tsis xav tias txawv txawv thaum koj pom nws dua yav tom ntej, thiab yuav tsis muaj teeb meem ntau zaus thaum siv. Zoo, qhov ntawd yog tag nrho rau cov ntsiab lus niaj hnub no, kuv ntseeg tias nws yuav coj cov ntsiab lus kev paub zoo dua.
