Pure hlau billets, tshwj xeeb tshaj yog hluav taws xob ntshiab hlau billets, muaj qhov zoo ntawm cov khoom siv hluav taws xob, ua rau lawv cov khoom siv zoo tshaj plaws rau cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab ntau yam kev siv high-tech. Cov hauv qab no yog cov ncauj lus kom ntxaws txog cov khoom siv hluav taws xob ntawm cov hlau ntshiab hlau:
1, Kev ua haujlwm zoo electromagnetic
〓 Tsawg coercivity: Coercivity (Hc) yog lub cev kom muaj nuj nqis uas ntsuas lub peev xwm ntawm cov khoom sib nqus los tswj lawv cov qub magnetization xeev tom qab tiv thaiv sab nraud magnetic teb. Qhov qis coercivity ntawm cov hlau nplaum ntshiab txhais tau hais tias lawv tau yooj yim dua los ntawm cov hlau nplaum sab nraud thiab feem ntau yuav poob lawv cov hlau nplaum tom qab tshem tawm cov hlau nplaum sab nraud, uas yog qhov tseem ceeb rau cov khoom siv hluav taws xob uas yuav tsum tau teb sai.
〓High magnetic permeability: Sib nqus permeability (μ) yog lub cev kom muaj nuj nqis uas piav txog qhov nyuaj ntawm kev sib nqus cov khoom sib nqus hauv cov hlau nplaum. Ntshiab hlau billets muaj siab sib nqus permeability, uas txhais tau hais tias lawv muaj peev xwm sai thiab tag nrho magnetize nyob rau hauv sab nraud magnetic teb, tsim muaj zog magnetic teb. Qhov no yog qhov tseem ceeb rau kev txhim kho kev ua tau zoo thiab kev ua haujlwm ntawm cov khoom siv electromagnetic.
〓High saturation magnetization: Saturation magnetization (Bs) yog qhov siab tshaj plaws sib nqus induction ua tiav los ntawm cov khoom sib nqus thaum lub sij hawm magnetization txheej txheem. Ntshiab hlau billets muaj siab saturation magnetic induction, uas txhais tau hais tias nyob rau hauv tib lub magnetic teb zog, lawv muaj peev xwm tsim kom muaj zog sib nqus induction siv, yog li txhim kho cov zis muaj peev xwm ntawm cov khoom siv electromagnetic.
2, ruaj khov thiab tsis sib nqus aging
Qhov sib nqus ruaj khov ntawm cov hlau ntshiab hlau tsis muaj qhov tshwm sim sib nqus aging. Magnetic aging yog hais txog qhov tshwm sim uas cov khoom sib nqus ntawm cov khoom sib nqus hloov tom qab lub sijhawm tom qab magnetization. Kev ruaj ntseg sib nqus ntawm cov hlau nplaum ntshiab txhais tau hais tias lawv tuaj yeem tswj cov khoom sib nqus ruaj khov thaum siv mus ntev, uas yog qhov tseem ceeb rau cov khoom siv hluav taws xob uas yuav tsum tau ua haujlwm ntev.
3, Kev siv dav dav
Vim nws zoo heev electromagnetic zog, ntshiab hlau billets muaj ntau yam kev siv nyob rau hauv ntau yam teb. Piv txwv li:
Electromagnetic Cheebtsam: Cov hlau nplaum ntshiab tuaj yeem siv los ua cov khoom siv hluav taws xob xws li hlau cores, relays, thiab solenoid li qub, uas ua lub luag haujlwm tseem ceeb hauv thaj chaw xws li lub zog, hluav taws xob, thiab kev sib txuas lus.
Cov khoom siv hluav taws xob: Cov hlau ntshiab hlau tseem tuaj yeem siv los ua cov ntaub thaiv npog rau cov khoom siv hluav taws xob kom txo tau qhov cuam tshuam ntawm electromagnetic cuam tshuam thiab hluav taws xob ntawm cov cuab yeej ua haujlwm.
Aerospace: Nyob rau hauv aerospace teb, ntshiab hlau billets yog siv los ua cov khoom tseem ceeb xws li dabtsi yog khoov thiab tsom hlau nplaum rau high-zog accelerators, electromagnetic separators rau geological instruments, thiab lwm yam. Cov khoom no tseem ceeb heev rau kev ua tau zoo thiab kev nyab xeeb ntawm aerospace khoom.
