The masana'antu tsari na high-yi NdFeb maganadiso wanda samar da Xinfeng Magnet ne yafi hada da: Xinfeng maganadisu high-yi Ndfeb maganadisu masana'antu tsari yafi hada da: albarkatun kasa pretreatment da batching, injin narkewa da tsiri simintin, hydrogen crushing da lafiya nika (iska niƙa). ) yin foda, foda forming da isostatic latsa, blank sintering da tsufa magani, magnet machining da sauran bakwai matakai.
(1) Pretreatment na danyen abu da batching: don cire baƙin ƙarfe oxide a saman saman ƙarfe mai tsabta, yanke sandar ƙarfe mai tsabta tare da tsayin 300mm tare da na'ura mai yankan, sa'an nan kuma saka shi a cikin injin fashewar harbi don cire tsatsa. , sa'an nan kuma aika shi zuwa wurin batching a cikin ganga don yin baking.Ana yin batching danye a cikin ɗakin batching.Dangane da wasan kwaikwayon, ana auna ma'aunin batching na albarkatun ƙasa kuma a sanya shi a cikin tankin ɗanyen abu, sannan a aika zuwa tanderun jefar.
(2) Vacuum simintin gyaran kafa
①Vacuum simintin: bayan duk rare duniya karafa da kuma wadanda ba rare ƙasa karafa a cikin crucible a cikin injin simintin makera an narke da kuma reacted gaba daya, da gami narke a hankali zuba a tsakiyar simintin jakar ta karkatar da crucible, da narkakkar karfe gami. ana zuba ruwa daidai gwargwado ga robar tagulla mai sanyayayar ruwa ta tsakiyar jakar.Ana sarrafa yawan zafin jiki tsakanin 1350 ℃ da 1450 ℃.Karkashin aikin dual na saurin sanyaya da jujjuyawar saurin sauri (wanda akafi sani da saurin saitin tsiri), ruwan gami da sauri ya rarrabu cikin flakes na NdFeb tare da kauri na 0.25 ~ 0.35mm.
②Cooling: Ana tattara flakes na NdFeb a cikin faifan sanyaya ruwa a ƙarƙashin nadi mai sanyi don sanyaya na biyu.Layout a kan faifan jujjuya na'urar na iya ƙara yawan sanyaya takardar NdFeb gami, bayan jiran alloy takardar sanyi sanyaya ƙasa 60 ℃, dauke da yanayin micro korau matsa lamba a cikin injin induction tanderu, ta amfani da iska ƙaura fanko na argon, sa'an nan bude tanda. kofa wucin gadi staging da gami takardar zuwa cikin musamman bakin karfe ganga ko cikin na gaba aiki hanya.
③Binciken ingancin samfur: kowane samfuran tanderu yakamata a ƙididdige samfuran don ingantacciyar dubawa don tabbatar da ko abun da ke cikin samfurin da aikin ya dace da buƙatun ingancin, samfuran da suka cancanta a cikin tsari na gaba, samfuran da ba su cancanta ba su dawo don tacewa.
(3) Ruwan ruwa na hydrogen: hydrogen crushing foda shine amfani da NdFeb hydrogen absorption kafin da kuma bayan ƙarar zai canza, don haifar da damuwa mai girma a cikin fashewar kayan ciki na ciki, don cimma tasirin murƙushewa.Tsarin murkushe hydrogen zai iya inganta ingantaccen injin niƙa, wanda ya fi sau biyu na tsarin gargajiya.
(4) Air niƙa foda: da gami foda bayan hydrogen crushing aka ɗora Kwatancen a cikin iska niƙa, a karkashin mataki na high-matsi nitrogen a matsa lamba na 0.7 ~ 0.8MPa, da karo tsakanin foda da kuma kara mai ladabi, da kuma ta hanyar rarrabuwa. tsarin don samun girman barbashi na 3 ~ 5μm magnetic foda.
(5) Molding: bayan foda yana hade da juna, ana amfani da filin magnetic 1.5t ~ 2.5T DC a ƙarƙashin yanayin kariyar nitrogen don yin magnetic foda tsari da tsari tare da jagorancin filin magnetic na waje, da matsa lamba na 0.1-1t / cm 2 ana amfani dashi don danna foda.Bayan dannawa, ana buƙatar filin maganadisu na baya na kusan 0.2 ~ 0.5 T don lalata billet ɗin.
(6) Sintering: foda billet an sanya a ko'ina a cikin kayan tire, sa'an nan sintered a cikin injin sintering tanderun (a cikin injin yanayi, da yawan zafin jiki ne kiyaye a 1000 ~ 1100 ℃), don samun dangi yawa daga ba kasa da 90% na sintered billet.
(7) Machining: bisa ga bukatun abokin ciniki, ta yin amfani da niƙa, hakowa, yankan waya da sauran hanyoyin sarrafa kayan aiki, NdFeb blank an sarrafa shi zuwa wani nau'i da girman (square, round, zobe da sauran siffofi) na maganadiso.
