Mokhoa oa ho hlahisa Sintered Neodymium Magnets?

Sintered NdFeB makeneteke makenete ea motsoako o entsoeng kaNd, Fe, B le likarolo tse ling tsa tšepe.E na le matla a khoheli a matla ka ho fetisisa, matla a qobelloang. E sebelisoa haholo ho li-mini-motors, lijenereithara tsa moea, limithara, li-sensor, libui, sistimi ea ho emisa makenete, mochini oa phetisetso ea makenete le lits'ebetso tse ling tsa indasteri. Ho bonolo haholo ho ba le ts'enyeho libakeng tse mongobo, kahoo ho bohlokoa ho etsa kalafo ea bokaholimo ho latela litlhoko tsa bareki. Re ka fana ka coatings, tse kang zinki, nikele, nikele-koporo-nikele, Silevera, khauta-plating, Epoxy barbotage, joalo-joalo Kereiti: N35-N52, N35M-48M, N33H-N44H, N30SH-N42SH, N28UH-N38UH, N28EH-N35EH

Tsamaiso ea Sintered Neodymium Magnet Production

step1

 

 

Lisebelisoa tsa matla a khoheli le lirafshoa tse ling li pepesetsoa maqhubu a mahareng ebe li qhibiliha seboping sa induction.

step1-1

 

 

 

 

 

 

step2

 

 

step2-2

Kamora ho phethela mehato e fapaneng ea ts'ebetso, li-ingots li silafatsoa ka likaroloana tse boholo ba microns. Bakeng sa ho thibela ho kenella ha oxidation, likaroloana tse nyane li sirelelitsoe ke naetrojene.

 

 

 

 

 

 

step3

 

 

step3-1

 

Matla a khoheli a beoa ka jig mme matla a khoheli a sebelisoa ha limakete li hatelloa ka libopeho haholo-holo. Kamora ho qaptjoa hoa pele, khatello ea oli isostatic e tla fetela pele ho theha libopeho.

 

 

 

 

 

step4

 

 

step4-1

 

Matla a khoheli a beoa ka har'a ingots e hatisitsoeng mme e tla phekoloa ka mocheso seboping sa sintering. Boima ba li-ingots tse fetileng bo otla feela 50% ea letsoalo la 'nete ho sintering. Empa kamora ho ts'oaroa, letsoalo la 'nete ke 100%. Ka ts'ebetso ena, tekanyo ea li-ingots e batla e fokotseha 70% -80% mme bophahamo ba eona bo fokotsoe ke 50%.

 

 

step5

 

 

step5-1

 

Lisebelisoa tsa mantlha tsa makenete li behiloe kamora hore ts'ebetso ea ho sintha le botsofali e phetheloe. Litekanyo tsa mantlha tse kenyeletsang masalla a ts'ebetsong ea masalla, matla a qobelloang le sehlahisoa se matla sa matla li tlalehiloe.

Ke limakete feela tse fetisitseng tlhahlobo tse romelloang lits'ebetsong tse latelang, joalo ka ho sebetsa le ho kopanya.

 

 

step6

 

 

step6-1

 

Ka lebaka la ho fokotseha ho tloha ts'ebetsong ea ho sintering, litekanyo tse hlokahalang li fihlelleha ka ho sila limakete ka li-abrasives. Li-abrasives tsa litaemane li sebelisetsoa ts'ebetso ena hobane makenete o thata haholo.

 

 

 

 

step7

 

 

step7-1

 

Ho lumellana hantle le tikoloho eo li tla sebelisoa ho eona, limakete li fuoa tse fapaneng mekhoa ea phekolo ea holim'a metsi. Magnet a Nd-Fe-B ka kakaretso a angoa ke mafome ka ponahalo e ts'oaroang joalo ka makenete a NiCuNi, Zn, Epoxy, Sn, Black Nickel.

 

 

 

step8

 

 

step8-1

Kamora ho roaloa, litekanyo tse amanang le tlhahlobo ea pono li tla etsoa ho netefatsa ponahalo ea sehlahisoa sa rona sa makenete. Ntle ho moo, ho etsa bonnete ba sebetsa ka ho nepahetseng phahameng, re boetse re lokela ho leka boholo bo ho laola mamello.

 

 

 

 

step9

 

 

step9-1

Ha ponahalo le boholo ba mamello ea makenete e tšoaneleha, ke nako ea ho etsa matla a khoheli a khoheli.

 

 

 

 

 

step10

 

 

step10-1

 

Kamora tlhahlobo le matla a khoheli, limakete li ikemiselitse ho paka ka lebokose la pampiri, esita le pallets ea lehong ho latela litlhoko tsa bareki. Matla a khoheli a ts'ebetsong a ka aroloa ka tšepe bakeng sa moea kapa polelo e hlahisang nako.
