Qhov sib xyaw ntawm cov hlau nplaum dag yog ua raws li kev sib nqus ntawm ntau yam hlau, raws li qhov xav tau.Cov hlau nplaum txuas mus (kov) cov khoom sib nqus uas yog induced ntawm ib qho kawg los ua ib lub npe ncej thiab nyob rau lwm qhov kawg los tsim ib lub npe ncej.
Kev faib tawm ntawm cov hlau nplaum A. Ib ntus (mos) hlau nplaum.Lub ntsiab lus: Magnetism yog ib ntus thiab ploj mus thaum cov hlau nplaum raug tshem tawm.Piv txwv li: hlau ntsia hlau, wrought hlau
Kev faib tawm ntawm cov hlau nplaum B. Permanent (hard) hlau nplaum.Lub ntsiab lus: Magnetism tuaj yeem khaws cia rau lub sijhawm ntev tom qab magnetization.Piv txwv li: tus ntsia thawv steel
Cov ntaub ntawv saum toj no tau sau tseg raws li hauv qab no: raws li lub hauv paus ntsiab lus ntawm electromagnetic induction, lub zog tam sim no tuaj yeem tsim kom muaj zog magnetic teb, thiab kev siv cov hlau nplaum muaj zog rau magnetize ferromagnetic tshuaj, thiab vim muaj qhov sib txawv magnetization yam ntxwv ntawm cov khoom sib txawv, qee qhov. Cov tshuaj yog yooj yim rau magnetize, thiab tsis yooj yim rau poob qhov sib nqus (magnetic poob), tuaj yeem khaws cov hlau nplaum ntev ntev.Magnetizing cov khoom no ua rau cov hlau nplaum.Cov hlau nplaum nyuaj yog magnetized nrog lub tshuab magnetizing.
Raws li lub hauv paus ntsiab lus ntawm electromagnetic induction, ib qho hluav taws xob tam sim no tuaj yeem tsim Magnetic teb uas siv lub teb muaj zog los ua kom muaj zog sib nqus.ACov khoom siv hlau nplaum, feem ntau hu ua hlau nplaum.Nws yog qhov tseeb ntau yam sib txawv: ib qho hlau nplaum sib xws, xws li ib qho siv hauv lub suab nrov nrov, yog ferromagnetic.Lawv yog siv nyob rau hauv cov txheej txheem ntawm kub dov hlau los ntawm cov hlau billet dov tawm ntawm lub nto ntawm hlau nplai (phaj zoo li tus hlau oxide), tom qab tshem tawm impurity, crushed, ntxiv ib me me ntawm lwm yam tshuaj nyob rau hauv lub steel pwm ntawm extrusion txoj kev, thiab Tom qab ntawd (hydrogen) hauv kev txo cov cua sov sintering, ua qee qhov oxide txo hauv ferrite, txias, thiab tom qab ntawd muab exciter rau hauv cov hlau nplaum.
Cov hlau nplaum ruaj khovzoo dua qhov no: Cov hlau nplaum tas mus li yog hlau, uas feem ntau muaj cov ntsiab lus ntau dua ntawm nickel, ntxiv rau hlau.Nws yog feem ntau melted los ntawm nruab nrab zaus hluav taws xob rauv (tsuas yog 100 kg ib lub cub tawg), casting molding, vim hais tias ib co ntawm nws lub dav hlau muaj precision yuav tsum, feem ntau yog siv ib tug grinder sib tsoo ua.Thiab ces magnetized rau hauv ib yam khoom.Hom hlau nplaum no yog siv rau hauv txhua hom hluav taws xob ntsuas.Cov khoom siv hlau nplaum zoo dua yogNdfeb Neodymium Magnet.Lawv yog cov khoom uas muaj cov ntsiab lus tsis tshua muaj hauv ntiaj teb neodymium, hlau thiab boron.
Kev tsim khoom yog tsim los ntawm txoj kev nyuaj alloy: tom qab Pulverizing - Mixing - Molding - Sintering - Finish - Magnetization.Hom kev sib nqus no muaj zog dua, kev ua tau zoo dua, tus nqi kim dua.Nws tsuas yog siv rau hauv rooj plaub ntawm cov khoom siv.Lub stepper lub cev muaj zog rotor hauv lub tshuab hluav taws xob saib yog lub tsheb ciav hlau sib nqus yuav tsum siv cov khoom sib nqus no.
ferrite ruaj nrees hlau nplaum cov ntaub ntawv yog: strontium-ferrite mus tas li sib nqus cov ntaub ntawv thiab barium ferrite mus tas li hlau nplaum cov ntaub ntawv, uas muaj isotropic thiab anisotropic ntsiab lus, hais lus hlau nplaum feem ntau yog siv ferrite mus tas li hlau nplaum cov ntaub ntawv;Cov khoom tseem ceeb ntawm cov hlau nplaum ruaj khov yogAlnico sib nqusthiab tsawg ntiaj teb cov khoom siv hlau nplaum ruaj khov.Cov hlau nplaum tsis tshua muaj hauv ntiaj teb tau muab faib ntxiv rauSmco Magnetsthiab NdFeb Magnets.Tsis tshua muaj ntiaj teb cov khoom siv hlau nplaum ruaj khov yog tsim los ntawm cov txheej txheem hmoov metallurgy.
