Yuav ua li cas neodymium hlau nplaum ua

Peb yuav piav qhia li casNdFeB hlau nplaumyog ua nrog cov lus piav qhia yooj yim. Cov hlau nplaum neodymium yog cov hlau nplaum ruaj khov ua los ntawm cov hlau nplaum ntawm neodymium, hlau, thiab boron los tsim Nd2Fe14B tetragonal crystalline qauv. Sintered neodymium hlau nplaum yog tsim los ntawm lub tshuab nqus tsev cua sov uas tsis tshua muaj lub ntiaj teb hlau raws li raw khoom nyob rau hauv lub cub tawg. Tom qab tau txais cov khoom siv raw, peb yuav ua 9 kauj ruam los ua cov hlau nplaum NdFeB thiab thaum kawg tsim cov khoom tiav.

Npaj cov ntaub ntawv rau reacting, melting, milling, nias, sintering, machining, plating, magnetization thiab tshuaj xyuas.

Npaj cov ntaub ntawv rau reacting

Cov tshuaj sib xyaw ua ke ntawm neodymium hlau nplaum yog Nd2Fe14B.

Cov hlau nplaum feem ntau yog Nd thiab B nplua nuj, thiab cov hlau nplaum tiav feem ntau muaj cov chaw tsis sib nqus ntawm Nd thiab B hauv cov nplej, uas muaj cov hlau nplaum Nd2Fe14B. nplej. Ob peb lwm yam tsis tshua muaj hauv ntiaj teb tuaj yeem muab ntxiv rau qee qhov hloov neodymium: dysprosium, terbium, gadolinium, holmium, lanthanum, thiab cerium. Tooj, cobalt, txhuas, gallium thiab niobium tuaj yeem muab ntxiv los txhim kho lwm yam khoom ntawm cov hlau nplaum. Nws yog ib txwm siv ob qho tib si Co thiab Dy ua ke. Tag nrho cov ntsiab lus los tsim cov hlau nplaum ntawm qib xaiv tau muab tso rau hauv lub tshuab nqus tsev induction rauv, rhuab thiab yaj los ua cov khoom siv hlau.

Melting

Cov ntaub ntawv raw yuav tsum tau yaj nyob rau hauv lub tshuab nqus tsev induction rauv los tsim Nd2Fe14B alloy. Cov khoom yog rhuab los ntawm kev tsim ib lub vortex, tag nrho cov nyob rau hauv lub tshuab nqus tsev vacuum los tiv thaiv cov kab mob los ntawm kev nkag mus rau cov tshuaj tiv thaiv. Cov khoom kawg ntawm cov kauj ruam no yog ib daim ntawv nyias-ribbon cam khwb cia (SC daim ntawv) muaj li niaj hnub Nd2Fe14B crystals. Cov txheej txheem melting yuav tsum tau ua nyob rau hauv lub sij hawm luv luv kom tsis txhob oxidation ntau dhau ntawm cov hlau tsis tshua muaj hauv ntiaj teb.

Milling

Cov txheej txheem 2-kauj ruam milling yog siv hauv kev tsim khoom. Thawj kauj ruam, hu ua hydrogen detonation, koom nrog cov tshuaj tiv thaiv ntawm hydrogen thiab neodymium nrog cov hlau, rhuav tshem SC flakes rau hauv cov khoom me me. Cov kauj ruam thib ob, hu ua dav hlau milling, hloov Nd2Fe14B cov khoom rau hauv cov khoom me me, nyob rau hauv txoj kab uas hla ntawm 2-5μm. Dav hlau milling txo cov khoom tsim los rau cov hmoov ntawm cov khoom me me. Qhov nruab nrab particle loj yog nyob ib ncig ntawm 3 microns.

Nias

NdFeB hmoov yog nias rau hauv ib qho khoom hauv cov duab uas xav tau hauv qhov chaw sib nqus muaj zog. Ib tug compressed khoom yuav tau txais thiab tuav ib tug nyiam magnetization orientation. Hauv cov txheej txheem hu ua tuag-upsetting, cov hmoov yog nias rau hauv cov khoom hauv qhov tuag ntawm li 725 ° C. Cov khoom yog tom qab ntawd muab tso rau hauv pwm thib ob, qhov twg nws yog compressed rau hauv cov duab dav, txog ib nrab ntawm nws qhov siab qub. Qhov no ua rau cov kev xav tau magnetization uas nyiam sib npaug rau cov kev taw qhia extrusion. Rau qee cov duab, muaj cov txheej txheem uas suav nrog cov clamps uas tsim kom muaj qhov chaw sib nqus thaum nias kom haum cov khoom.

Sintering

Nias NdFeB cov khib nyiab yuav tsum tau sintered los tsim NdFeB blocks. Cov khoom siv yog compressed ntawm qhov kub thiab txias (txog 1080 ° C) hauv qab lub melting point ntawm cov khoom kom txog rau thaum nws cov particle adheres rau ib leeg. Cov txheej txheem sintering muaj 3 kauj ruam: dehydrogenation, sintering thiab tempering.

Tshuab dhos

Sintered hlau nplaum raug txiav rau hauv cov duab uas xav tau thiab loj siv cov txheej txheem sib tsoo. Tsawg dua, cov duab nyuaj hu ua cov duab tsis tu ncua yog tsim los ntawm kev siv hluav taws xob tawm hluav taws xob (EDM). Vim yog tus nqi ntawm cov khoom siv siab, cov khoom poob vim yog machining yog khaws cia rau qhov tsawg kawg nkaus. Huizhou Fullzen Technology yog qhov zoo heev ntawm kev tsim cov hlau nplaum tsis sib xws.

Plating / Txheej

Uncoated NdFeB yog corroded heev thiab poob nws cov hlau nplaum sai sai thaum ntub dej. Yog li, tag nrho cov khoom lag luam muaj neodymium hlau nplaum yuav tsum tau txheej. Cov hlau nplaum ib leeg yog plated hauv peb txheej: npib tsib xee, tooj liab thiab npib tsib xee. Rau ntau hom txheej txheej, thov nyem "Tsuas hu rau peb".

Magnetization

Cov hlau nplaum yog muab tso rau hauv ib qho khoom siv uas nthuav tawm cov hlau nplaum mus rau qhov chaw sib nqus muaj zog heev rau lub sijhawm luv luv. Nws yog ib qho loj coil qhwv ib ncig ntawm cov hlau nplaum. Cov khoom siv hlau nplaum siv cov tsev txhab nyiaj capacitor thiab cov hluav taws xob siab heev kom tau txais qhov muaj zog tam sim no hauv lub sijhawm luv luv.

Kev tshuaj xyuas

Tshawb xyuas qhov zoo ntawm cov hlau nplaum uas ua rau muaj ntau yam ntxwv. Digital ntsuas qhov projector txheeb xyuas qhov ntev. Txheej thickness ntsuas tshuab siv X-ray fluorescence thev naus laus zis txheeb xyuas qhov tuab ntawm txheej txheej. Kev ntsuam xyuas tsis tu ncua hauv cov tshuaj tsuag ntsev thiab kev ntsuas lub siab cooker kuj txheeb xyuas qhov ua tau zoo ntawm txheej txheej. Daim ntawv qhia hysteresis ntsuas BH nkhaus ntawm cov hlau nplaum, paub meej tias lawv tau magnetized tag nrho, raws li xav tau rau chav kawm hlau nplaum.

Thaum kawg peb tau txais cov khoom zoo tshaj plaws hlau nplaum.
