Cob phum cov hlau nplaum tshem tawm txoj kab
Abstract: Lub dag zog hlau nplaum yog lub tshuab hluav taws xob uas muaj qhov sib txawv ntawm lub ntiaj teb tsis tshua muaj hlau nplaum cov khoom uas muaj coercivity siab thiab siab remanence, neodymium hlau boron thiab ferrite rau ib qho chaw muaj zog magnetic, uas yog siv los ntxaum ferromagnetic impurities. Tag nrho cov tshuab tsis muaj zog. Tsis muaj zog noj. Kev ruaj khov hlau nplaum hlau tshem tawm tau muab faib ua av tsis tuaj yeem ua kom tsis ncaj, tsis tuaj yeem ncav tsis pub hlau ntim, tsis tuaj yeem ua haujlwm tawm hlau. Qhov kev tshem tawm hlau txoj kev ntawm cov hlau nplaum sab nraud cais yog raws li nram no:
(1) Siv hom phom sij ntau lawm. Txoj kev siv hom sib nqus nrawm nrawm muaj tus yam ntxwv ntawm kev rho tawm hlau tsis zoo, tsis muaj kev sib hloov hauv qhov chaw, tsis muaj kev hloov hauv txias thiab kub, ob peb qhov tsis ua tiav, thiab daim ntawv thov nyob rau hauv 1200 mm bandwidth ntau dua. Txij li thaum txoj kev loj hlob ntawm kev sib txig sib txig sib txig tsis dhau, nws tau ua teeb meem ntau los tsim, kev thauj mus los, kev teeb tsa, kev khiav lag luam thiab kev kho. Piv txwv li, ib qho hlau loj yog nqus ntawm lub npov hlau nplaum thiab muaj teeb meem uas nws yuav tsis raug muab pov tseg thiab siv txoj siv mus rau lub tshuab. Nyob rau tib lub sij hawm, nws yog ib qho nyuaj rau tshem tawm, thiab tej zaum yuav ua kev puas tsuaj rau qhov sib nqus thaiv, yog li nws yuav raug rau qee cov kev txwv ntawm cov ntawv teev npe loj.
(2) Khoom neeg tsim tawm cov hlau nplaum sab nraud. Nyob rau hauv tag nrho cov hlau separators, nws yog yooj yim, tus nqi yog tsawg, qhov chaw nyob yog me me, thiab tsim kev tsim thiab txij nkawm yog yooj yim. Raws li txoj kev teeb tsa yuav tsum tau muab faib ua ob qho, xws li, ncua kev ncua kev kawm thiab hauv qab tas. Tshem tawm cov ntawv phom plhis yog tsim rau kev sib txuas rau ntawm daim kab xev siv txoj hlua, thaum lub caij nrawm qab plag remover yog tsim rau kev txhim kho hauv qab plaw los yog chute. Cov hom hlau no tshem tawm yog tsim rau me thiab tsis muaj iron-impurities, thiab thauj khoom siv tuab tsawg tshaj 100 hli. Thaum lub tshuab ua haujlwm, cov hlau ntxim nyiam ncaj qha mus rau cov phom sij, thiab cov ntawv tsis tuaj yeem yuav tsum tau muaj, uas yog haujlwm.
(3) Kev cob qhia sab nraud hlau nplaum tshem tawm. Cov hom phom ntau lawm ntawm cov tshuab nqus hlau tau muab tshem tawm cov hlau los ntawm kev siv cov xuab zeb kom khawb cov hlau tawm sab nraud ntawm cov hlau nplaum uas siv khawb, tab sis feem ntau nws tsis tuaj yeem siv rau hauv daim ntaub ntawv nrog cov hlau loj.
Separators yog siv rau hauv metallurgy, mining, coal preparation plants, fais fab nroj tsuag, ceramics, iav, cement, cov ntaub ntawv hauv tsev, tshuaj, khoom noj khoom haus, thiab pub ua lag luam. Hauv kev lag luam kev tsim kho khib nyiab, steel kuj xav tau kom tshem tawm seem ntawm cov hlau cais. Tshwj xeeb tshaj yog nyob rau hauv cov thee thiab ceramic industries, detonators, rau tes, thiab lwm yam iron impurities tov nyob rau hauv thee tsis tsuas yog cuam tshuam rau kev ruaj ntseg ntau lawm, tab sis kuj rau qhov zoo thiab lub koob npe nrov ntawm cov hluav taws xob export; limestone, silica, dolomite, feldspar, thiab lwm yam siv nyob rau hauv cov kev lag luam ntawm cov khoom ua paj Raw cov ntaub ntawv feem ntau muaj hlau thiab hlau sib txuas ntau los tsawg dua. Hlau yog ib qhov muaj teeb meem loj rau cov khoom siv ua xua. Nws feem ntau ua rau xim av los sis dub rau sab nraud ntawm cov plag tsev, uas cuam tshuam cov xim ntawm cov khoom thiab txo cov qhab nia ntawm cov khoom siv ua xua. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tau siv hlau tshem tawm kom tshem tawm cov hlau.
