Inkqubo yokwenziwa kwemagnethi ephezulu ye-NdFeb eveliswe yi-Xinfeng Magnet ibandakanya ikakhulu: i-Xinfeng umazibuthe ophezulu-ukusebenza kweNdfeb umazibuthe inkqubo yokuvelisa ikakhulu ibandakanya: pretreatment ekrwada kunye batching, vacuum ukunyibilika kunye strip yokuphosa, hydrogen ukutyunyuzwa kunye nokusila kakuhle (moya yokusila ) ukwenza umgubo, ukwenza umgubo kunye nocinezelo lwe-isostatic, ukuthunga okungenanto kunye nonyango lokwaluphala, ukwenziwa kwemagnethi kunye nezinye iinkqubo ezisixhenxe.
1 , kwaye emva koko uyithumele kwindawo yokudibanisa kwimibhobho yokudibanisa.Ukudibanisa izinto eziluhlaza kuqhutyelwa kwigumbi lokudibanisa.Ngokwentsebenzo, umlinganiselo we-batching we-raw material ulinganiswe kwaye ubekwe kwitanki yezinto ezikrwada, emva koko ithunyelwe kwi-vacuum casting oven.
(2) Ukukhupha ivacuum
① I-vacuum casting: emva kokuba zonke iintsimbi ezinqabileyo zomhlaba kunye nesinyithi zomhlaba ezingaqhelekanga kwi-crucible kwi-vacuum casting thernece ziyanyibilika kwaye ziphendule ngokupheleleyo, i-alloy iyancibilika ngokukhawuleza igalelwe kwingxowa ephakathi yokuphosa ngokutyekisa i-crucible, kunye ne-alloy metal etyhidiweyo. i-liquid igalelwe ngokulinganayo kwi-roller yobhedu epholileyo yamanzi ejikelezayo ngengxowa ephakathi.Ubushushu bokugalela bulawulwa phakathi kwe-1350 ℃ kunye ne-1450 ℃.Ngaphantsi kwesenzo esiphindwe kabini sokupholisa okukhawulezileyo kunye nokujikeleza kwesantya esiphezulu (esaziwa njenge-strip yokuseta ngokukhawuleza), ulwelo lwe-alloy lujiyelwe ngokukhawuleza kwi-NdFeb alloy flakes kunye nobukhulu be-0.25 ~ 0.35mm.
②Ukupholisa: I-NdFeb i-alloy flakes iqokelelwa kwi-disk epholile ngamanzi phantsi komqulu obandayo wokupholisa okwesibini.Ubeko kwisixhobo esijikelezayo sedisk kunokonyusa isantya sokupholisa sephepha le-NdFeb, emva kokulinda ukupholisa ubushushu beshiti le-alloy ngaphantsi kwe-60 ℃, phakamisa imeko yoxinzelelo oluncinci olubi kwi-vacuum induction furnace, usebenzisa i-air displacement yokukhupha i-argon, emva koko uvule i-oven. umnyango owenziweyo ubeka iphepha lealloyi kumbhobho okhethekileyo wentsimbi engenasici okanye kwinkqubo yokusebenza elandelayo.
③Ukuhlolwa komgangatho wemveliso: imveliso nganye yeziko kufuneka ithathwe iisampulu yokuhlolwa komgangatho ukuqinisekisa ukuba ukwakhiwa kwemveliso kunye nokusebenza kuyahlangabezana neemfuno zomgangatho, iimveliso ezivunyiweyo kwinkqubo elandelayo, iimveliso ezingenakufaneleka zibuyele ekusulungekisweni.
(3) I-Hydrogen yokutyumza: i-hydrogen yokutyumza i-powder kukusetyenziswa kwe-NdFeb i-hydrogen absorption ngaphambi nangemva kokuba umthamo uya kutshintsha, ukwenzela ukuba uvelise uxinzelelo olukhulu ekuqhekekeni kwayo kwangaphakathi kwezinto, ukufezekisa umphumo wokutyumza.Inkqubo yokutyumza i-Hydrogen inokuphucula ukusebenza kakuhle kwe-air Mill, engaphezulu kwamaxesha amabini enkqubo yendabuko.
(4) Umgubo wokugaya umoya: i-alloy powder emva kokutyumzwa kwe-hydrogen ilayishwe kwi-air Mill, phantsi kwesenzo se-nitrogen ephezulu yoxinzelelo lwe-0.7 ~ 0.8MPa, ukungqubana phakathi komgubo kunye nokucocwa ngakumbi, kunye nokuhlelwa inkqubo ukufumana ubungakanani amasuntswana 3 ~ 5μm ngumgubo magnetic.
5 I-cm 2 isetyenziselwa ukucofa umgubo.Emva kokucinezela, umva umhlaba wemagnethi omalunga ne-0.2 ~ 0.5 T usafuneka ukwenza i-billet ingasebenzi.
(6) I-Sintering: i-powder billet ibekwe ngokulinganayo kwi-tray yezinto eziphathekayo, kwaye emva koko ifakwe kwi-vacuum sintering eziko (kwindawo yokucoca, iqondo lobushushu ligcinwa kwi-1000 ~ 1100 ℃), ukufumana ukuxinana kwesalamane esingekho ngaphantsi kwe. I-90% ye-billet ye-sintered.
(7) Umatshini: ngokweemfuno zomthengi, usebenzisa ukugaya, ukugaya, ukusika ucingo kunye nezinye iindlela zokulungisa oomatshini, i-NdFeb engenanto icutshungulwa ibe yimo ethile kunye nobukhulu (isikwere, ukujikeleza, umsesane kunye nezinye iimilo) zeemagnethi.
