Magnets AlNiCo Tayada Sareysa Ayaa La Heli Karaa

AlNiCo Magnets Tayada Sare leh oo La Heli karo Sawirka sifaysan

Sharaxaad Gaaban:

Magnet-ka joogtada ah ee Alnico waa daawaha ka kooban curiyeyaasha sida aluminium (Al), nikkel (Ni), kobalt (Co) iyo birta (Fe).Waxay leedahay sifooyin birlabeed sare leh waxayna ku ilaalin kartaa guryaha birlabeedka oo deggan heerkulka sare.Magnets joogto ah ee Alnico waxaa caadi ahaan loo isticmaalaa soo saarista qaybaha kala duwan ee magnetic, sida dareemayaasha, matoorada iyo koronto-dhaliyeyaasha.

Agabka birlabeedka joogtada ah ee Alnico looma qaabayn karo sidii qaybo dhismeed oo ay ugu wacan tahay sifooyinka awooda farsamaysan ee hooseeya, engegnaanta sare, jajabnaanta, iyo mashiinada liidata.Kaliya wax yar shiidi ama EDM ayaa la isticmaali karaa inta lagu jiro farsamaynta, hababka kale sida foornada iyo mashiinada kale lama isticmaali karo.

AlNiCo waxaa inta badan lagu soo saaraa habka wax shubidda.Intaa waxaa dheer, biraha budada ah ayaa sidoo kale loo isticmaali karaa in lagu sameeyo magnets sintered, kaas oo leh waxqabad yar oo hooseeya.Cast AlNiCo waxaa loo habayn karaa cabbirro iyo qaabab kala duwan halka alaabada AlNiCo ee la jeexjeexay ay inta badan yihiin kuwo yaryar.Qaybaha shaqada ee AlNiCo ee sintered waxay leeyihiin dulqaad cabbir ka wanaagsan, sifooyinka birlabku wax yar bay ka hooseeyaan laakiin mashiinnada ayaa ka wanaagsan.

Faa'iidada AlNiCo magnets waa dib u soo noolaansho sare (ilaa 1.35T), laakiin yaraanta ayaa ah in xoogga wax lagu qasbay uu aad u hooseeyo (badanaa wax ka yar 160kA/m), qalooca demagnetization waa mid aan toos ahayn, markaa AlNiCo waa magnet si sahlan loo heli karo. Noqo magnetized iyo sidoo kale si sahlan loo demagnetized.Marka nakhshadeynta wareegga magnetic iyo soo saarista qalabka, fiiro gaar ah waa in la bixiyaa oo magnetka waa in hore loo dejiyaa.Si looga fogaado qayb ka mid ah demagnetization ama qalloocin qaybinta cufnaanta qulqulka magnetic, waxaa si adag loo mamnuucay in lala xiriiro walxo ferromagnetic inta lagu jiro isticmaalka.

Cast AlNiCo magnet joogto ah ayaa leh heerkulka ugu hooseeya ee dib loo rogi karo oo ka mid ah qalabka magnetka joogtada ah, heerkulka shaqadu wuxuu gaari karaa ilaa 525 ° C, iyo heerkulka Curie ilaa 860 ° C, taas oo ah walxaha magnetka joogtada ah ee leh barta Curie ee ugu sareysa.Sababtoo ah xasilloonida heerkulka wanaagsan iyo xasilloonida gabowga, magnets AlNiCo ayaa si fiican loogu dabaqay matoorada, aaladaha, aaladaha korantada, iyo mashiinnada magnetic, iwm.
