Kumanani ndi ine chimodzi mwazinthu zakale kwambiri zamaginito - AlNiCo

Chithunzi cha AlNiCo

Alnico maginitondi chimodzi mwa zinthu zoyamba kupanga maginito okhazikika, ndi aloyi wopangidwa ndi aluminiyamu, faifi tambala, cobalt, chitsulo ndi zinthu zina zachitsulo. Alnico okhazikika maginito zinthu zidapangidwa bwino mu 1930s. Pamaso pa kupangidwa kwa osowa padziko lapansi okhazikika maginito zipangizo mu 1960s, zotayidwa faifi tambala-cobalt aloyi wakhala amphamvu maginito okhazikika zipangizo maginito, koma chifukwa zikuchokera njira zitsulo cobalt ndi faifi tambala, chifukwa cha mtengo wapamwamba, ndi Kubwera kwa ferrite maginito okhazikika ndi maginito osowa padziko lapansi okhazikika, zida za aluminium-nickel-cobalt muzinthu zambiri zimasinthidwa pang'onopang'ono. Komabe, ena mkulu kutentha ntchito ndimkulu maginitozofunikira zokhazikika, maginito akadali ndi malo osagwedezeka.

Njira yopanga Alnico ndi mtundu

Alnico maginitokukhala ndi njira ziwiri zoponyera ndi sintering, ndipo njira yoponyera imatha kusinthidwa kukhala makulidwe ndi mawonekedwe osiyanasiyana; Poyerekeza ndi njira yoponyera, mankhwala opangidwa ndi sintered amangokhala ndi kukula kwazing'ono, kulolerana kwapang'onopang'ono kwa zopanda kanthu zomwe zimapangidwira zimakhala bwino kusiyana ndi zomwe zilibe kanthu, katundu wa maginito ndi wotsika pang'ono kusiyana ndi wazitsulo, koma machinability ndi bwino.

Kapangidwe ka aluminium faifi tambala cobalt ndi batching → kusungunuka → kuponyera → kutentha kutentha → kuyezetsa ntchito → Machining → kuyang'anira → kuyika.
Sintered aluminiyamu faifi tambala cobalt amapangidwa ndi ufa zitsulo, njira kupanga ndi batching → ufa ufa → kukanikiza → sintering → kutentha kutentha → kuyezetsa ntchito → Machining → kuyendera → ma CD.

Malingaliro a kampani AlNiCo

Maginito otsalira a maginito azinthuzi ndi okwera, mpaka 1.35T, koma mphamvu zawo zamkati ndizochepa kwambiri, nthawi zambiri zimakhala zosakwana 160 kA / m, piritsi lake la demagnetization ndilosiyana, ndipo aluminium faifi tambala cobalt okhazikika maginito kuzungulira sikugwirizana. ndi curve demagnetization, kotero chidwi chapadera chiyenera kuperekedwa kuzomwe zimapangidwira popanga ndi kupanga maginito amagetsi a chipangizocho. Maginito okhazikika ayenera kukhazikika pasadakhale. Mwachitsanzo, aloyi wapakatikati wa anisotropic cast AlNiCo, kapangidwe ka Alnico-6 ndi 8% Al, 16% Ni, 24% Co, 3% Cu, 1% Ti, ndi ena onse Fe. Alnico-6 ili ndi BHmax ya 3.9 megagauss-oesteds (MG·Oe), coercivity ya 780 oersted, kutentha kwa Curie kwa 860 ° C, ndi kutentha kwakukulu kwa 525 ° C. Malinga ndi otsika coercivity Al-Ni-Co okhazikika maginito zakuthupi, ndi zoletsedwa kukhudzana ndi chilichonse ferromagnetic zakuthupi pa ntchito, kuti asapangitse m'deralo zosasinthika demagnetization kapena kupotoza kwamphamvu ya maginitokachulukidwe kugawa.

Komanso, pofuna kulimbitsa kukana kwake kwa demagnetization, pamwamba pa Alnickel-cobalt okhazikika maginito pole nthawi zambiri amapangidwa ndi mizati yaitali kapena ndodo yaitali, chifukwa alnickel-cobalt okhazikika maginito chuma ali otsika makina mphamvu, mkulu kuuma ndi brittleness, chifukwa. mu machinability osauka, kotero izo sizingakhoze kupangidwa ngati gawo structural, ndipo kokha pang'ono akupera kapena EDM akhoza kukonzedwa, ndi forging ndi makina processing zina. sungagwiritsidwe ntchito. Hangzhou maginito Power Technology Co., Ltd. ali mwatsatanetsatane akupera luso la mankhwala, kulondola processing akhoza lizilamulira mkati +/-0.005 mm, ndipo ali kupanga ndi processing luso la zinthu zooneka ngati mwapadera, kaya zinthu ochiritsira kapena ochiritsira mankhwala apadera apadera, tikhoza kupereka njira yoyenera ndi pulogalamu.

Malo ogwiritsira ntchito Alnico

Zida zopangira aluminium-nickel-cobalt zimagwiritsidwa ntchito kwambiri poyezera, maginito a zida, zida zamagalimoto, zomvera zapamwamba, zida zankhondo ndi zakuthambo ndi zina. Sintered aluminiyamu faifi tambala cobalt ndi oyenera kupanga zinthu zovuta, kuwala, woonda, ang'onoang'ono, makamaka ntchito mauthenga pakompyuta, okhazikika maginito makapu, magnetoelectric masiwichi ndi masensa osiyanasiyana Zogulitsa zambiri mafakitale ndi ogula ayenera kugwiritsa ntchito maginito amphamvu okhazikika, monga motors, gitala lamagetsi lamagetsi, maikolofoni, oyankhula masensa, machubu oyendayenda, (cowmagnet) ndi zina zotero. Onse amagwiritsa ntchito maginito a aluminium-nickel-cobalt. Koma tsopano, mankhwala ambiri akusintha kuti agwiritse ntchito maginito osowa padziko lapansi, chifukwa mtundu uwu wa zinthu ukhoza kupatsa mphamvu ya Br ndi BHmax yapamwamba, kulola kuti chiwerengero chochepa cha mankhwala.
