Imagnethi ye-cobalt yaseSamarium (i-SmCo) yayihlala isetyenziswa njengenketho yeemeko ezingqongileyo ezigqithisileyo zokumelana nobushushu obuphezulu.Kodwa yintoni iqondo lokushisa elilinganiselwe le-samarium cobalt?Lo mbuzo uba ngakumbi kwaye ubaluleke ngakumbi njengoko inani leemeko zezicelo ezigqithisileyo lisanda.Ubushushu beCurie bezinto zeferromagnetic budla ngokuba ngumda ophezulu wobushushu besicelo.Ngaphezulu kobu bushushu, umazibuthe uyatshintsha ukusuka kwimo ye-ferromagnetic ukuya kwimeko yeparamagnetic, kwaye akasenazo iimpawu ezinamandla zemagnethi.Umzekelo, ubushushu beCurie be-2:17 SmCo bumalunga nama-820°C, kwaye elo le-1:5 SmCo limalunga ne-750°C.Ukubunjwa kunye nokwakheka kweemagnethi zihlala zihluke, ubushushu beCurie buhluke kancinane, kodwa ngokuqhelekileyo kuloluhlu.Njengoko uMfanekiso 1 ubonisiwe.
Umzobo 1. Ubushushu beCurie bezinto ezahlukeneyo zemagnethi ezisisigxina
Nangona kunjalo, kwisicelo sokwenyani, iimagnethi ze-SmCo zithambekele ekulahlekeni kwemagnethi engenakubuyiselwa xa ubushushu bungaphantsi kakhulu kunobushushu beCurie.Ubushushu obukhulu (Tmax) be-SmCo bukhawulelwe ngumlinganiso wobushushu wokunyanzeliswa kunye nendawo yokusebenza ebangelwa yimilo eyahlukeneyo yeemagnethi.Ukuba i-BH ijika kwi-quadrant yesibini isetyenziswe njengomgca othe ngqo njengomgangatho wokugweba (i-Chen, i-JAP, i-2000), i-Tmax yeemagnethi ze-SmCo ezisetyenziswa ngokuqhelekileyo ayidluli i-350 ° C.Njengoko kuboniswe kwi-Figure 2, iimpawu ezigqwesileyo zamagnetic ze-32H umazibuthe kwi-20 °C yi-Br≥11.3kGs, i-Hcj≥28kOe, i-Hk≥21kOe, kunye ne-BHmax≥30.5kOe.Nangona kunjalo, i-coefficient yeqondo lokushisa β (20-350 ° C) ye-intrinsic coercivity Hcj yi-0.042%, kwaye i-curve yayo ye-BH kusenzima ukugcina umgca othe ngqo kwi-quadrant yesibini kwi-350 ° C.
Umzobo 2, ijika lobushushu le-32H.
I-Hangzhou Magnet Power Co.Ltd iphuhlise uthotho lweemagnethi zeSmCo ezixhathisa ubushushu obuphezulu (T series) ukusuka kuma-350 °C ukuya kuma-550 °C.Njengoko kubonisiwe kuMfanekiso 3, ezi magnethi zisuka kwi-T350 ene-Tmax ye-350 °C ukuya kwi-T550 ene-Tmax ye-550 °C.Ngomsebenzi othile, nceda ujonge ikhonkco lewebhusayithihttps://www.magnetpower-tech.com/t-series-sm2co17-smco-magnet-supplier-product/.Le nto ifanelekile kwizicelo zokushisa eziphezulu ezifana neshishini lemichiza, i-turbine kunye nokunye.
