Iyo neodymium magineti inogadzirwa sei

Tichatsanangura seiNdFeB maginetizvinogadzirwa netsanangudzo iri nyore.Iyo neodymium magineti igineti yechigarire yakagadzirwa kubva kune alloy ye neodymium, iron, uye boron kuumba iyo Nd2Fe14B tetragonal crystalline chimiro.Sintered neodymium magineti anogadzirwa nekudziya kwevacuum isingawanzo simbi yepasi semidziyo yakabikwa muchoto.Mushure mekuwana zvigadzirwa, isu tichaita 9 matanho ekugadzira NdFeB magineti uye pakupedzisira kuburitsa zvigadzirwa zvapera.

Gadzirira zvinhu zvekuita, kunyunguduka, kugaya, kudzvanya, sintering, machining, plating, magnetization uye kuongorora.

Gadzirira zvinhu zvekuita

Iyo kemikari musanganiswa fomu ye neodymium magineti ndeye Nd2Fe14B.

Magnets anowanzo kuve Nd uye B akapfuma, uye apedzwa magineti anowanzo ane nonmagnetic nzvimbo dzeNd uye B muzviyo, izvo zvine yakanyanya magineti Nd2Fe14B.zviyo.Zvimwe zvakawanda zvisingawanzo zvinhu zvepasi zvinogona kuwedzerwa kutsiva zvishoma neodymium: dysprosium, terbium, gadolinium, holmium, lanthanum, uye cerium.Mhangura, cobalt, aluminium, gallium uye niobium inogona kuwedzerwa kuvandudza zvimwe zvinhu zvemagineti.Zvakajairika kushandisa zvese Co uye Dy pamwechete.Zvese zvinhu zvekugadzira magineti egiredhi rakasarudzwa zvinoiswa muchoto chevacuum induction, inopisa uye yakanyungudutswa kugadzira iyo alloy zvinhu.

Melting

Izvo zvigadzirwa zvinoda kunyungudutswa muchoto chevacuum induction kuumba iyo Nd2Fe14B alloy.Chigadzirwa chacho chinodziiswa nekugadzira vortex, zvese zviri pasi pevacuum kudzivirira kusvibiswa kupinda mukuita.Chigadzirwa chekupedzisira chenhanho iyi pepa rakatetepa-ribhoni rakakandwa (SC sheet) inoumbwa neyunifomu Nd2Fe14B makristasi.Iyo yekunyunguduka inoda kuitwa munguva pfupi kwazvo kudzivirira yakawandisa oxidation yeasingawanzo pasi simbi.

Kugaya

Iyo 2-nhanho yekugaya inoshandiswa mukugadzira maitiro.Danho rekutanga, rinonzi hydrogen detonation, rinosanganisira kuita pakati pehydrogen neodymium nealloy, kutyora maSC flakes kuita twudiki.Nhanho yechipiri, inonzi jet milling, inoshandura Nd2Fe14B zvimedu kuita zvidimbu zvidiki, kubva padhayamita kubva 2-5μm.Jet milling inoderedza zvinhu zvinenge zvabuda kuita hupfu hudiki diki saizi.Avhareji saizi yepakati inotenderedza 3 microns.

Kudzvanya

NdFeB poda inomanikidzwa kuita yakasimba muchimiro chaidiwa mune yakasimba magineti.Iyo yakamanikidzwa yakasimba inowana uye inochengetedza yakasarudzika magineti yekutarisa.Mune imwe nzira inonzi die-upsetting, poda inotsikirirwa kuita yakasimba mufa inokwana 725°C.Iyo yakasimba inobva yaiswa muforoma yechipiri, umo inotsikirirwa kuita chimiro chakafara, inenge hafu yehurefu hwayo hwepakutanga.Izvi zvinoita kuti yakasarudzika magineti nzira ifanane neiyo extrusion nzira.Kune mamwe maumbirwo, kune nzira dzinosanganisira zvisungo zvinoburitsa magineti panguva yekudzvanya kuti ienzanise zvimedu.

Sintering

Yakadzvanywa NdFeB solids inoda kusiiwa kuti igadzire NdFeB blocks.Nyaya yacho inomanikidzwa pakupisa kwepamusoro (kusvika ku1080 ° C) pasi pekunyunguduka kwezvinhu kusvikira zvikamu zvaro zvanamatira kune mumwe.Iyo sintering process ine matanho matatu: dehydrogenation, sintering uye tempering.

Machining

Sintered magineti anochekwa kuita anodiwa zvimiro uye saizi uchishandisa nzira yekukuya.Zvishoma zvakajairika, maumbirwo akaomarara anonzi maumbirwo asina kujairika anogadzirwa neelectric discharge machining (EDM).Nekuda kwekudhura kwezvinhu, kurasikirwa kwezvinhu nekuda kwekugadzira machining kunochengetwa kushoma.Huizhou Fullzen Technology yakanaka kwazvo pakugadzira magineti asina kujairika.

Plating / Coating

Uncoated NdFeB yakasvibiswa zvakanyanya uye inorasikirwa nemagnetism nekukasira kana yanyorova.Saka, ese anotengeswa neodymium magineti anoda coating.Magineti ega ega akaputirwa muzvikamu zvitatu: nickel, mhangura uye nickel.Kuti uwane mamwe marudzi ekuputira, tapota tinya "Contact Us".

Magnetization

Iyo magineti inoiswa mugadziriso inoburitsa magineti kune yakasimba kwazvo magineti kwechinguva chidiki.Ikoiri hombe yakamonerwa nemagineti.Magnetized madivayiri anoshandisa capacitor mabhangi uye akanyanya kukwira voltages kuti awane simba rakadaro munguva pfupi.

Inspection

Tarisa hutano hwemagineti anoguma kune akasiyana maitiro.Digital yekuyera purojekita inosimbisa zviyero.Coating ukobvu hwekuyera masisitimu anoshandisa X-ray fluorescence tekinoroji inosimbisa ukobvu hwemachira.Kugara uchiyedzwa mumunyu wekupfapfaidza uye kudzvanywa cooker bvunzo zvakare inosimbisa mashandiro eiyo coating.Mepu yehysteresis inoyera BH curve yemagineti, ichisimbisa kuti akazara magineti, sezvinotarisirwa kukirasi yemagineti.

Pakupedzisira takawana chakanakira magineti chigadzirwa.
