Kuumbwa kweAlNiCo
Alnico maginetindeimwe yekutanga kugadzira magineti echigarire, ialloy inoumbwa nealuminium, nickel, cobalt, iron uye zvimwe zvinoteedzera simbi zvinhu. Alnico zvachose magineti zvinhu zvakabudirira kugadzirwa muma1930s. Pamberi pekugadzirwa kwezvinhu zvisingawanzo pasi zvemagineti zvechigarire muma1960s, aluminium-nickel-cobalt alloy yakagara iri iyo yakasimba magineti inogara magineti zvinhu, asi nekuda kwekuumbwa kwestrategic simbi cobalt uye nickel, zvichikonzera kukwira kwemitengo, nekuuya kwe. ferrite isingaperi magineti uye isingawanzo pasi isingaperi magineti, aluminium-nickel-cobalt zvinhu mune akawanda maapplication akatsiviwa zvishoma nezvishoma. Nekudaro, mune mamwe epamusoro-tembiricha maapplication uyehigh magnetickugadzikana zvinodiwa, iyo magineti ichiri kubata isingazununguki chinzvimbo.
Alnico kugadzira maitiro uye mhando
Alnico maginetiIva nemaitiro maviri ekukanda uye sintering, uye maitiro ekukanda anogona kugadziriswa muhukuru hwakasiyana uye maumbirwo; Kuenzaniswa neyekukanda maitiro, iyo sintered chigadzirwa inogumira kune diki saizi, saizi yekushivirira kweiyo isina chinhu inogadzirwa iri nani pane iyo yakakandwa chigadzirwa chisina chinhu, iyo magineti pfuma yakadzikira zvishoma pane iyo yechigadzirwa chakakandwa, asi machinability iri. nani.
Iyo yekugadzira maitiro ekukanda aluminium nickel cobalt iri batching → kunyungudika → kukanda → kupisa kupisa → kuyedza kuita → machining → kuongorora → kurongedza.
Sintered aluminium nickel cobalt inogadzirwa nehupfu metallurgy, maitiro ekugadzira ari kubatch → kugadzira hupfu → kudzvanya → sintering → kupisa kupisa → kuyedza kuita → machining → kuongorora → kurongedza.
Kuita kweAlNiCo
Iyo yakasara yemagineti inoyerera yechinhu ichi yakakwira, inosvika 1.35T, asi kumanikidza kwavo kwemukati kwakadzikira, kazhinji isingasviki 160 kA/m, demagnetization curve yayo haina mutsara shanduko, uye iyo aluminium nickel cobalt inogara magineti loop haipindirani. ine demagnetization curve, saka kutarisisa kwakanyanya kunofanirwa kubhadharwa kune yayo chaiyo kana kugadzira uye kugadzira iyo magineti yedunhu remudziyo. Iyo magineti yechigarire inofanirwa kugadzikiswa pachine nguva. Semuenzaniso wepakati anisotropic cast AlNiCo alloy, kuumbwa kweAlnico-6 ndeye 8% Al, 16% Ni, 24% Co, 3% Cu, 1% Ti, uye mamwe ese Fe. Iyo Alnico-6 ine BHmax ye3.9 megagauss-oesteds (MG·Oe), kumanikidza kwe780 oersted, Curie tembiricha ye860 °C, uye yakanyanya tembiricha yekushanda ye525 °C. Zvinoenderana nekushomeka kwakaderera kweAl-Ni-Co zvachose magineti zvinhu, zvinorambidzwa zvachose kubata chero ferromagnetic zvinhu panguva yekushandiswa, kuitira kuti zvisakonzeresa kusagadziriswa demagnetization kana kukanganisamagnetic fluxdensity distribution.
Uye zvakare, kuitira kusimbisa kwayo demagnetization kuramba, iyo nzvimbo yeAlnickel-cobalt inogara magineti pole inowanzogadzirwa nembiru refu kana matanda marefu, nekuti iyo alnickel-cobalt inogara magineti zvinhu ine yakaderera mechani simba, kuoma kwakanyanya uye brittleness, zvichikonzera. mukushaya machinability, saka haigoni kugadzirwa sechikamu chekugadzirisa, uye zvishoma zvishoma zvekukuya kana EDM inogona kugadziriswa, uye kuumba uye mamwe maitiro ekugadzirisa. haigoni kushandiswa. Hangzhou Magnet Power Technology Co., Ltd. ine chaiyo yekukuya kugona kwechigadzirwa ichi, iko kurongeka kwekugadzirisa kunogona kudzorwa mukati me +/- 0.005 mm, uye ine kugadzirwa uye kugadzirisa kugona kwezvigadzirwa zvine chimiro chakasarudzika, ingave zvigadzirwa zvakajairika kana yakakosha-yakaumbwa zvigadzirwa, tinogona kupa nzira yakakodzera uye chirongwa.
Nzvimbo dzekushandisa dzeAlnico
Cast aluminium-nickel-cobalt zvigadzirwa zvinonyanya kushandiswa mukuyera, magineti emidziyo, zvikamu zvemotokari, yepamusoro-yekupedzisira odhiyo, midziyo yemauto uye aerospace nemimwe minda. Sintered aluminium nickel cobalt inokodzera kugadzirwa kwezvinhu zvakaoma, zvinyoro, zvitete, zvidiki, zvinonyanya kushandiswa mukukurukurirana kwemagetsi, makapu echigarire magineti, magnetoelectric switch uye akasiyana masensor Zvigadzirwa zvakawanda zveindasitiri nevatengi zvinoda kushandisa magineti akasimba echigarire, senge mota, emagetsi gitare pickups, maikorofoni, sensor speaker, kufamba wave machubhu, (cowmagnet) zvichingodaro. Vese vanoshandisa aluminium-nickel-cobalt magineti. Asi ikozvino, zvigadzirwa zvakawanda zviri kuchinja kushandisa zvisingawanzo pasi magineti, nokuti rudzi urwu rwezvinhu runogona kupa Br yakasimba uye yakakwirira BHmax, ichibvumira chiyero chiduku chechigadzirwa.
