Yuav ua li cas neodymium magnets tau ua

Peb yuav piav qhia li casNdFeB hlau nplaumyog ua nrog ib qho lus piav qhia yooj yim. Lub hlau nplaum neodymium yog lub hlau nplaum tas mus li ua los ntawm cov hlau nplaum ntawm neodymium, hlau, thiab boron los tsim cov qauv crystalline Nd2Fe14B tetragonal. Cov hlau nplaum neodymium sintered yog ua los ntawm lub tshuab nqus tsev cua sov cov hlau tsis tshua muaj hauv av ua cov khoom siv raw hauv lub cub tawg. Tom qab tau txais cov khoom siv raw, peb yuav ua 9 kauj ruam los ua NdFeB hlau nplaum thiab thaum kawg tsim cov khoom tiav.

Npaj cov ntaub ntawv rau kev ua tshuaj, yaj, milling, nias, sintering, machining, plating, magnetization thiab kev tshuaj xyuas.

Npaj cov ntaub ntawv rau kev ua tshuaj

Cov tshuaj sib xyaw ua ke ntawm neodymium magnet yog Nd2Fe14B.

Cov hlau nplaum feem ntau yog Nd thiab B nplua nuj, thiab cov hlau nplaum tiav lawm feem ntau muaj cov chaw tsis yog hlau nplaum ntawm Nd thiab B hauv cov noob, uas muaj cov noob Nd2Fe14B uas muaj hlau nplaum heev. Muaj ntau lwm cov khoom tsis tshua muaj nyob hauv ntiaj teb tuaj yeem ntxiv los hloov qee qhov neodymium: dysprosium, terbium, gadolinium, holmium, lanthanum, thiab cerium. Tooj liab, cobalt, txhuas, gallium thiab niobium tuaj yeem ntxiv los txhim kho lwm yam khoom ntawm cov hlau nplaum. Nws yog ib qho uas siv ob qho tib si Co thiab Dy ua ke. Txhua yam khoom siv los tsim cov hlau nplaum ntawm qib xaiv tau muab tso rau hauv lub tshuab cua sov induction, cua sov thiab yaj los ua cov khoom siv hlau nplaum.

Yaj

Cov khoom siv raw yuav tsum tau yaj hauv lub tshuab cua sov nqus tsev kom tsim tau Nd2Fe14B alloy. Cov khoom raug cua sov los ntawm kev tsim lub vortex, txhua yam nyob rau hauv lub tshuab nqus tsev kom tiv thaiv kev ua qias tuaj yeem nkag mus rau hauv cov tshuaj tiv thaiv. Cov khoom kawg ntawm cov kauj ruam no yog daim ntawv nyias-ribbon cast (SC daim ntawv) uas muaj cov khoom siv Nd2Fe14B sib xws. Cov txheej txheem yaj yuav tsum tau ua tiav hauv lub sijhawm luv luv kom tsis txhob muaj kev oxidation ntau dhau ntawm cov hlau tsis tshua muaj.

Kev Sib Tsoo

Cov txheej txheem milling 2-kauj ruam yog siv rau hauv kev xyaum tsim khoom. Kauj ruam thawj zaug, hu ua hydrogen detonation, cuam tshuam nrog kev sib xyaw ntawm hydrogen thiab neodymium nrog cov hlau sib xyaw, rhuav cov SC flakes ua cov khoom me me. Kauj ruam thib ob, hu ua jet milling, tig cov khoom me me Nd2Fe14B mus ua cov khoom me me, uas muaj txoj kab uas hla ntawm 2-5μm. Jet milling txo cov khoom ua tiav mus rau cov hmoov ntawm cov khoom me me heev. Qhov nruab nrab ntawm cov khoom me me yog li 3 microns.

Kev nias

Hmoov NdFeB raug nias rau hauv ib lub khoom khov uas zoo li koj xav tau hauv ib lub zog sib nqus muaj zog. Ib lub khoom khov uas raug nias yuav tau txais thiab tswj tau qhov kev taw qhia magnetization uas nyiam. Hauv ib txoj kev hu ua die-upsetting, cov hmoov raug nias rau hauv ib lub khoom khov hauv lub pwm ntawm li 725 ° C. Tom qab ntawd cov khoom khov raug muab tso rau hauv lub pwm thib ob, qhov chaw uas nws raug nias rau hauv ib lub duab dav dua, kwv yees li ib nrab ntawm nws qhov siab qub. Qhov no ua rau qhov kev taw qhia magnetization nyiam sib luag rau qhov kev taw qhia extrusion. Rau qee cov duab, muaj cov txheej txheem uas suav nrog clamps uas tsim lub zog sib nqus thaum lub sijhawm nias kom phim cov khoom me me.

Kev Sintering

Cov khoom NdFeB uas raug nias yuav tsum tau sintered los ua cov NdFeB blocks. Cov khoom siv raug nias ntawm qhov kub siab (txog li 1080 ° C) hauv qab qhov chaw yaj ntawm cov khoom kom txog thaum nws cov khoom sib txuas ua ke. Cov txheej txheem sintering muaj 3 kauj ruam: dehydrogenation, sintering thiab tempering.

Kev siv tshuab

Cov hlau nplaum sintered raug txiav rau hauv cov duab thiab qhov loj me uas xav tau siv cov txheej txheem sib tsoo. Tsis tshua muaj, cov duab nyuaj hu ua cov duab tsis sib xws yog tsim los ntawm kev siv hluav taws xob (EDM). Vim yog tus nqi khoom siv siab, kev poob khoom vim yog kev siv tshuab raug khaws cia kom tsawg kawg nkaus. Huizhou Fullzen Technology zoo heev ntawm kev tsim cov hlau nplaum tsis sib xws.

Plating/Txheej

NdFeB uas tsis tau pleev xim yog xeb heev thiab poob nws lub zog magnetic sai sai thaum ntub. Yog li, txhua lub hlau nplaum neodymium uas muaj nyob hauv khw yuav tsum tau pleev xim. Cov hlau nplaum ib leeg tau pleev xim rau hauv peb txheej: nickel, tooj liab thiab nickel. Yog xav paub ntxiv txog hom txheej, thov nyem "Tiv Tauj Peb".

Kev sib nqus

Lub hlau nplaum raug muab tso rau hauv ib lub teeb uas ua rau lub hlau nplaum raug rau lub zog sib nqus muaj zog heev rau lub sijhawm luv luv. Nws zoo li lub kauj loj uas qhwv ib ncig ntawm lub hlau nplaum. Cov khoom siv sib nqus siv cov capacitor banks thiab cov hluav taws xob siab heev kom tau txais hluav taws xob muaj zog heev hauv lub sijhawm luv luv.

Kev Tshuaj Xyuas

Tshawb xyuas qhov zoo ntawm cov hlau nplaum uas tau los rau ntau yam ntxwv. Lub tshuab ntsuas digital ntsuas qhov ntev. Cov txheej txheem ntsuas tuab txheej siv cov thev naus laus zis X-ray fluorescence txheeb xyuas qhov tuab ntawm cov txheej. Kev sim tsis tu ncua hauv kev sim tshuaj tsuag ntsev thiab lub lauj kaub siab kuj txheeb xyuas qhov ua tau zoo ntawm cov txheej. Daim ntawv qhia hysteresis ntsuas qhov nkhaus BH ntawm cov hlau nplaum, lees paub tias lawv tau magnetized tag nrho, raws li xav tau rau chav kawm hlau nplaum.

Thaum kawg peb tau txais cov khoom zoo tagnrho magnet.
