Iziko leFrequency ePhakathi
I eddy yangoku eyenziwa yiUKUBA ezikoKwakhona inezinye iimpawu ze-intermediate frequency current, oko kukuthi, ii-electron zamahhala zentsimbi ngokwayo zihamba kumzimba wesinyithi ngokuxhathisa ukuvelisa ubushushu.Uhlobo lwebhulorho yesigaba esithathu-elawulwa ngokupheleleyo isekethe yokulungisa isetyenziselwa ukulungisa umsinga oguqukayo ube ngumbane othe ngqo.Ngokomzekelo, i-cylinder yensimbi ifakwe kwi-coil induction kunye ne-intermediate intermediate current current.I-cylinder yensimbi ayidibanisi ngokuthe ngqo kunye ne-coil induction, kwaye ukushisa kwe-coil ene-energized ngokwayo kuphezulu kakhulu.Ephantsi, kodwa umphezulu we-cylinder ushushu ukuya kwinqanaba lobomvu kunye nokuncibilika, kwaye isantya sobubomvu kunye nokunyibilika kunokufezekiswa kuphela ngokulungelelanisa ukuphindaphinda kunye namandla akhoyo.Ukuba i-cylinder ifakwe kumbindi wekhoyili, iqondo lokushisa elijikeleze i-cylinder liya kuba lifanayo, kwaye ukufudumeza kunye nokunyibilika kwe-cylinder akuyi kuvelisa iigesi ezinobungozi okanye kungcolise indalo ngokukhanya okunamandla.
Umgaqo wokusebenza:
Ii-intermediate frequency furnaceikakhulu iqulunqwe ngumbane, i-coil induction kunye ne-crucible eyenziwe ngezinto eziphikisayo kwi-coil induction.I-crucible igcwele intlawulo yetsimbi, elingana ne-second winding ye-transformer.Xa i-coil induction ixhunywe kumandla ombane we-AC, i-alternating field magnetic iveliswa kwi-coil induction, kwaye imigca yayo yamagnetic yamandla inqumle intlawulo yetsimbi kwi-crucible, kwaye i-electromotive force eyenziwe kwintlawulo.Ekubeni umrhumo ngokwawo wenza i-loop evaliweyo, ukuvuthwa kwesibini kubonakala ngokujika okukodwa kwaye kuvaliwe.Ngako oko, i-current induced current ikhiqizwa kwintlawulo ngexesha elifanayo, kwaye xa i-current induced idlula kwintlawulo, intlawulo iyatshisa ukukhuthaza ukunyibilika kwayo.
Iziko lombane eliphakathi kwamaza ombane lisebenzisa unikezelo lwamandla ombane ophakathi ukuseka intsimi yemagnethi ephakathi, ukuze i-eddi yangoku iveliswe ngaphakathi kwemathiriyeli yeferromagnetic kwaye ivelise ubushushu, ukuze kufezekiswe injongo yokufudumeza imathiriyeli.Iziko lombane eliphakathi kwamaza ombane lithatha i-200-2500Hz unikezelo lwamandla ombane ophakathi ukufudumeza, ukunyibilikisa kunye nokugcina ubushushu.Iziko lombane eliphakathi rhoqo lisetyenziselwa ukunyibilikisa intsimbi yekhabhoni, intsimbi yealloy, intsimbi ekhethekileyo, kwaye ingasetyenziselwa ukunyibilikisa kunye nokufudumeza iintsimbi ezingenayo intsimbi ezifana nobhedu kunye nealuminium.Isixhobo sincinci ngobukhulu kwaye silula ngobunzima.Ukukhanya, ukusebenza kakuhle okuphezulu, ukusetyenziswa kwamandla aphantsi, ukunyibilika ngokukhawuleza kunye nokufudumeza, ukulawula lula ubushushu bomlilo, kunye nokusebenza kakuhle kwemveliso.
