Njira yopangira maginito a neodymium ndi yofanana ndi njerwa yomangira yomwe imayikidwa mu chitofu chotentha kwambiri.Ndi chithandizo cha kutentha kwambiri, chimapangitsa njerwa kukhala yolimba komanso yolimba.
Njira yayikulu yopanga maginito a neodymium ndi njira yosinthira, ndichifukwa chake timatcha maginito a sintering neodymium.Zosakaniza zazikulu ndi neodymium(Nd 32%), Ferrum(Fe 64%) ndi Boron(B 1%), ndichifukwa chake timatchanso maginito a neodymium kukhala maginito a NdFeB.The sintering ndondomeko amatetezedwa ndi mpweya inert (monga nayitrogeni, argon kapena helium mpweya) mu ng'anjo vacuum, monga maginito particles ndi ang'onoang'ono monga 4 microns, zosavuta kuyaka, ngati aonekera mu mlengalenga, zosavuta oxidized ndi kugwira moto, kotero timawateteza ndi gasi wa inert panthawi yopanga, ndipo zimatenga pafupifupi maola 48 mu sintering stove.Pokhapokha sintering tingathe kukwaniritsa olimba ndi amphamvu maginito ingots.
Kodi maginito ingots ndi chiyani?Tili ndi maginito maginito omwe adapanikizidwa mu nkhungu kapena zida, ngati mukufuna maginito a disc, ndiye kuti tili ndi nkhungu ya chimbale, ngati mukufuna maginito a block, ndiye kuti tili ndi nkhungu ya bock, maginito amakanizidwa mu nkhungu yachitsulo ndikutuluka. maginito ingots, ndiye tili ndi izi maginito ingots kutentha ankachitira mu ng'anjo sintering kukwaniritsa boma olimba.Kachulukidwe ka ma ingots musanayambe sintering ndi pafupifupi 50% ya kachulukidwe weniweni, koma mutatha kupukuta, kachulukidwe kowona ndi 100%.Neodymium maginito kachulukidwe ndi 0.0075 magalamu pa kiyubiki millimeters.Kupyolera mu njirayi, miyeso ya maginito ingots imachepa ndi 70% -80% ndipo voliyumu yawo imachepetsedwa ndi 50%.Kukalamba maginito ingots pambuyo sintering kusintha katundu wa zitsulo.
Zinthu zoyambira maginito zimayikidwa pambuyo poti sintering ndi ukalamba watha.
Miyezo yofunikira ya maginito kuphatikiza kuchuluka kwa remanence flux, coercivity, ndi kuchuluka kwamphamvu kwamagetsi kumalembedwa mufayilo.Ndi maginito okhawo omwe amadutsa pakuwunikako ndi omwe amatumizidwa kunjira zotsatizana ndi machining, plating, magnetizing ndikupanga msonkhano womaliza, ndi zina zambiri.
Nthawi zambiri timakwaniritsa zofunikira zololera zamakasitomala pogwiritsa ntchito makina, kugaya ndi ma abrasives, monga maginito slicing adzakhala ngati CNC Machining, etc. ife makonda makina apadera kupanga processing osiyana pa maginito.Pali ntchito zambiri zoti zichitike kuti zikwaniritse zofunikira za makasitomala.
