Boitsebiso ba Alnico Magnet



Tlhaloso

Lisebelisoa tsa Alnico (tse entsoeng haholo ka aluminium, nickel le cobalt tse nang le likarolo tse nyane tsa likarolo tse ling ho kenyeletsoa titanium le koporo) li lumella libaka tsa moralo tse fanang ka matšoao a phahameng, matla a phahameng le likhatello tse phahameng haholo. Limenete tsa Alnico li khetholloa ka botsitso bo botle ba mocheso le ho hanela demagnetization hantle ho tloha thothomelo le tšabo. Magnete a Alnico a fana ka litšobotsi tse ntle ka ho fetisisa tsa mocheso oa makenete efe kapa efe e tloaelehileng ea tlhahiso e fumanehang. Li ka sebelisoa bakeng sa lits'ebetso tse tsoelang pele tsa ts'ebetso moo ho ka lebelloang mocheso o feteletseng ho fihlela 930F.

Magnet a Alnico a etsoa ka mokhoa oa ho lahla kapa oa ho sintering. Alnico makenete e thata haholo ebile e brittle. Ho sebetsa kapa ho cheka ho ke ke ha etsoa ka mekhoa e tloaelehileng. Hangata likoti li koaletsoe setsing sa motheo. Magnets li lahleloa kapa sintered haufi-ufi kamoo ho ka khonehang ho hlokahala boholo bo lekaneng e le hore khorofo sila ho qeta litekanyo le tolerances e minimized

Mekhoa e ikhethang ea ho betsa e sebelisetsoang ho fihlela mokhoa o ikhethileng oa mabele a kristale a fumanoang limhlopheng tsa alnico 5 le 8. Limaraka tsena tsa anisotropic li etselitsoe ho hlahisa matla a phahameng a khoheli ka tsela e boletsoeng. Tloaelo e fihlelleha nakong ea kalafo ea mocheso, ka ho pholisa ho lahla ho tloha 2000F ka sekhahla se laoloang ka har'a matla a khoheli a lumellanang le tataiso e ratoang ea matla a khoheli. Alnico 5 le Alnico 8 ke li-anisotropic mme li bonts'a tataiso e khethiloeng ea boits'oaro, mokhoa oa matla a khoheli o lokela ho hlalosoa setšoantšong sa hau ha o re romella taelo.

Cast Alnico 5 ke eona e sebelisoang ka ho fetesisa ho Alnico's kaofela. E kopanya lipontšo tse phahameng le sehlahisoa se phahameng sa matla sa 5 MGOe kapa ho feta mme e sebelisoa haholo mochineng oa ho potoloha, likhokahano, limithara le lisebelisoa, lisebelisoa tsa kutlo le lits'ebetso tse ts'oereng. Khanyetso e phahameng ea demagnetization (matla a qobelloang) ea Alnico 8, e nang le cobalt ho 35%, e lumella lisebelisoa tsena hore li sebetse hantle bakeng sa bolelele bo khuts'oane kapa bolelele ho isa ho bophara bo ka tlase ho 2 ho 1.

Lisebelisoa tsa Sintered Alnico li fana ka likarolo tse tlase tsa matla a khoheli empa ke litšoaneleho tsa botoro ho feta lisebelisoa tsa Alnico. Limenetara tsa Sintered Alnico li loketse haholo ka boholo bo bonyenyane (ka tlase ho 1 oz.) Ts'ebetsong ena. Motsoako o lakatsehang oa phofo ea tšepe o petelitsoe hore o bōpehe le boholo ka har'a sefu, ebe o sintered ka 2300 F ka har'a hydrogen. Ts'ebetso ea ho sintering e loketse tlhahiso ea molumo o moholo, 'me e fella ka likarolo tse matla ho feta limenete tse lahliloeng. Mamello e haufi e ka fihlelleha ntle le ho sila.


Molemo oa Kholisano:
Litšobotsi tsa Alnico Magnet:

* Liphetoho tse nyane ho likarolo tsa matla a khoheli ho isa liphellong tsa mocheso
* Mocheso o phahameng oa ho sebetsa o ka ba 450oC ~ 550oC.
* Matla a tlase a qobelloang.
* Matla matla ts'enyeho hanyetsa, ha ho barbotage hlokahala bakeng sa tšireletso ea holim.

• E loketse limagnet tse nyane tse nang le sebopeho se rarahaneng
• Kristale e kopaneng, matla a phahameng
• Sebopeho sa kamehla, boholo bo nepahetseng
• Le likarolo, ts'ebetso e tsitsitseng
• E loketse bakeng sa makenete a kopaneng
• Botsitso bo babatsehang ba mocheso (co. Coefficient ea Br ke e nyane haholo hara limakete tse ling tsohle tsa ka ho sa feleng
