Inkqubo yokuvelisa imagnethi ye-neodymium iyafana njengesitena sokwakha esifakwe kwisitovu sobushushu obuphezulu. Ngonyango oluphezulu lweqondo lokushisa, lenza isitena siqine kwaye somelele.
Eyona nkqubo yokuvelisa imagnethi ye-neodymium yinkqubo yokuntywila, yiyo loo nto siyibiza ngokuba yimagnethi ye-neodymium. Izithako eziphambili ziyi-neodymium(Nd 32%), iFerrum(Fe 64%) kunye neBoron(B 1%), yiloo nto sikwabiza iimagnethi ze-neodymium ukuba zibe ziimagnethi zeNdFeB. Inkqubo ye-sintering ikhuselwe ngegesi ye-inert (efana ne-nitrogen, i-argon okanye i-helium gas) kwisithando somlilo, njengoko amasuntswana magnetic mancinci njenge-microns ezi-4, ezivuthayo ezilula, ukuba zibonakaliswe emoyeni, kulula ukuba zifakwe kwi-oxidized kwaye zibambe umlilo, ngoko. sizikhusela ngerhasi engasebenziyo ngexesha lemveliso, kwaye kuya kuthatha malunga neeyure ezingama-48 kwisitovu sokutshiza. Kuphela emva kokuba sintering singakwazi ukufikelela eyomeleleyo kwaye eyomeleleyo ingots umazibuthe.
Yintoni iingots zemagnethi? Sinamasuntswana omagnetic acinezelwe kubumba okanye isixhobo, ukuba ufuna idisc umazibuthe, emva koko sinobumba idiski, ukuba ufuna ibhloko umazibuthe, emva koko sinobumba be-bock, amasuntswana omagnetic acinezelwe kubumba lwentsimbi kwaye aphume. ingots umazibuthe, ke sinazo ezi ingots umazibuthe ephathwa eziko sintering ukuphumeza imo eqinileyo. Ubuninzi bee-ingots ngaphambi kokuntywila malunga ne-50% yoxinaniso lokwenyani, kodwa emva kokuntywila, ubuninzi bokwenyani yi-100%. Uxinzelelo lwemagnethi ye-Neodymium yi-0.0075 gram nge-cubic millimeters nganye. Ngale nkqubo i-ingots yemagnethi icutheka malunga ne-70% -80% kwaye umthamo wazo uncitshiswe malunga ne-50%. Ukuguga iingots umazibuthe emva sintering ukulungelelanisa iimpawu zesinyithi.
Iimpawu ezisisiseko zemagneti zisetwa emva kokuba iinkqubo ze-sintering kunye nokuguga zigqityiwe.
Imilinganiselo yeempawu zemagneti eziphambili ezibandakanya ukuxinana kwe-remanence flux, ukunyanzeliswa, kunye nemveliso yamandla aphezulu irekhodwa kwifayile. Kuphela ezo zimagnethi zigqithise uhlolo ziya kuthunyelwa kwiinkqubo ezilandelayo zokuqhubela phambili umatshini, ukucwenga, ukwenza imagnethi kunye nokwenza indibano yokugqibela, njl.
Ngokuqhelekileyo sifezekisa iimfuno zokunyamezela kwabathengi ngomatshini, ukugaya kunye neebrasives, ezifana ne-magnet slicing iya kufana ne-CNC machining, njl. Mninzi umsebenzi ekufuneka wenziwe ukuhlangabezana neemfuno ezizodwa zabathengi.
