Isithando somlilo esiphakathi sisixhobo sombane esiguqula amandla angama-50Hz AC abe ngamaza ombane aphakathi (300Hz ukuya kwi-100Hz) amandla, emva koko aguqule amandla amanqanaba amathathu e-AC abe ngamandla eDC, aze ke aguqule amandla eDC abe yi-adjustable intermediate frequency current, ethi ihamba ngee-capacitors kunye neekhoyili ze-induction.Velisa imigca yamandla emagnethi enoxinaniso oluphezulu, unqumle imathiriyeli yentsimbi kwikhoyili yokungeniswa, sebenzisa umgaqo wokungeniswa kwe-electromagnetic ukuvelisa i-eddy yangoku yemathiriyeli yentsimbi, ukufudumeza imathiriyeli yesinyithi, kwaye uyinyibilikise.
I-furnace ye-frequency induction ephakathi ngumthwalo wenkqubo ecacileyo.Ngexesha lenkqubo yokusebenza, imisinga ye-harmonic yaziswa kwigridi yamandla, ibangela i-pulse yangoku amandla ombane kwi-impedance yeempawu zegridi yamandla, ibangela ukuguquguquka kwamandla ombane kwigridi yamandla, kwaye ichaphazela umgangatho wenkqubo yonikezelo lwamandla kunye nokhuseleko lokusebenza kwezixhobo. .Ukusukela oko unikezelo lwamandla orhwebo lweziko eliphakathi luba sisantya esiphakathi ngokuguqulelwa kohlengahlengiso, igridi yamandla iya kuvelisa inani elikhulu lee-harmonics ezinobungozi obuphezulu ngexesha lokusebenza, engomnye weyona mithombo mikhulu ye-harmonic ekwi-oda ephezulu. umthwalo wegridi yamandla.
Iimpawu ezintlanu zesithando somlilo esiphakathi
1. Yonga imali
Ukufudumeza ngokukhawuleza, imveliso ephezulu, i-air oxidation carburization encinci, ukugcinwa kwezinto eziluhlaza kunye neendleko, kunye nokwandisa ubomi benkonzo yezixhobo eziqhumayo.
Ngenxa yokuba umgaqo we-intermediate frequency induction furnace yi-electromagnetic, ubushushu obuveliswa sisithando somlilo esiphakathi senziwa yintsimbi ngokwayo.Abasebenzi abaqhelekileyo banokuqhuba umsebenzi oqhubekayo wokwenza umsebenzi kwimizuzu elishumi emva kokusebenzisa i-intermediate frequency induction furnace, ngaphandle kwesidingo sokwenziwa kwesithando somlilo.Abasebenzi baqalisa umsebenzi wokudubula kunye nokutywina kwangaphambili.Ngenxa yokuba le ndlela yokufudumeza itshisa ngokukhawuleza kwaye ine-oxidation encinci, ukuchithwa kwe-oxidation ye-intermediate frequency yokufudumeza i-castings yensimbi yi-0.5% kuphela, ukukhupha i-oxidation yokufudumeza kwegesi yegesi yi-2%, kwaye i-furnace yamalahle ekrwada idlula i-3%.Inkqubo yokufudumeza isantya esiphakathi igcina i-Raw materials, xa kuthelekiswa neziko lamalahle akrwada, itoni enye yentsimbi yokusa igcina i-20-50KG iipleyiti zentsimbi ezingenasici.Izinga layo lokusetyenziswa kwezinto eziluhlaza lingafikelela kwi-95%.Ngenxa yokuba ukufudumeza kufana kwaye umahluko weqondo lokushisa phakathi kwendawo engundoqo incinci, ubomi benkonzo yokufa kwe-forging banda kakhulu ngexesha lokubumba.Uburhabaxa bokwenza bungaphantsi kwe-50um, kwaye iteknoloji yokucubungula igcina amandla.Ukufudumeza okuphakathi kwamaza ombane kunokonga amandla ngama-31.5% -54.3% xa kuthelekiswa nokufudumeza kwe-oyile, kunye nokufudumeza kwegesi Ukonga amandla nge-5% -40%.Umgangatho wokufudumeza ulungile, izinga le-scrap lingancitshiswa nge-1.5%, izinga lokuphuma linganyuswa nge-10% -30%, kwaye ubomi benkonzo yesixhobo esiqhekezayo bunokwandiswa nge-10% -15%.
2. Amanqaku okhuseleko lokusingqongileyo
Ubume be-ofisi obugqwesileyo, buphucule ubume be-ofisi yabasebenzi kunye nembonakalo yegama lenkampani, ungcoliseko lwezero, ukonga umbane.
Xa kuthelekiswa nezitofu zamalahle, izitofu zokufudumala ze-induction azikwazi ukutshaya izitofu zamalahle phantsi kobushushu obukhulu, ezinokuhlangabezana nemimiselo ye-Arhente yoKhuseleko lweNdalo.Ukongeza, inokubumba umfanekiso wophawu lwangaphandle lwenkampani kwaye yenze umkhondo wophuhliso loshishino lweshishini lemveliso.Ukufudumala kwe-induction kukufudumala kwamandla ombane wesithando sombane ukusuka kwiqondo lokushisa ukuya kwi-100 ° C, ukusetyenziswa kwamandla kungaphantsi kwe-30 ° C, kwaye ukusetyenziswa kwe-forgings kungaphantsi kwe-30 ° C.Indlela yokwahlula yokwenziwa kokusetyenziswa
3. Ukufudumeza iziqhamo
Ukufudumala okufanayo, umehluko omncinci wokushisa phakathi kwengundoqo kunye nomhlaba, ukuchaneka kokulawula ubushushu obuphezulu
Ukufudumeza kwe-Induction kuvelisa ubushushu kwintsimbi ngokwayo, ngoko ke ukufudumeza kuyalingana kwaye umahluko weqondo lokushisa phakathi kwengundoqo kunye nomphezulu omncinci.Ukusetyenziswa kwenkqubo yokulawula ubushushu kunokulawula ngokuchanekileyo ubushushu, ukuphucula umgangatho wemveliso kunye nezinga lokupasa.
4. Izinga
Isithando somlilo esiphakathi sitshisa ngokukhawuleza, isinyithi esinyibilikayo sisebenzisa amandla e-electromagnetic angadlulanga kwii-degrees ezingama-500, kwaye ukunyibilika kugqibelele kwaye ngokukhawuleza.
5. Ukusebenza kokhuseleko
Inkqubo yokubeka iliso ekude ye-intermediate frequency electric furnace ikhethiwe, efanelekileyo kwindawo yokuvelisa imveliso.Ikhono elinamandla lokuchasana nokuphazamiseka kunye nokhuseleko oluphezulu.Akukho cingo oluxhunyiwe phakathi kwesixhobo sokusebenza kunye nesixhobo esilawulwayo, oko kukuthi, ulawulo olude.Kuyo yonke imisebenzi entsonkothileyo, cofa amaqhosha olawulo olukude umgama.Emva kokufumana imiyalelo, i-intermediate frequency electric furnace inokugqiba imisebenzi ehambelanayo inyathelo ngesinyathelo ngokwenkqubo elungileyo.Ngenxa yokuba isithando sombane sisixhobo sombane esine-voltage ephezulu, asikhuselekanga kuphela, kodwa sinokuphepha umonakalo kwisithando sombane ngenxa yokwesaba okubangelwa yimpazamo yokusebenza.
Kutheni isithando somlilo esiphakathi sivelisa i-harmonics
I-Harmonics iya kubeka emngciphekweni kakhulu ukusebenza ngokukhuselekileyo kwegridi yamandla.Ngokomzekelo, i-harmonic yangoku iya kubangela ilahleko eyongezelelweyo ye-vortex yentsimbi ephezulu-frequency ephezulu kwi-transformer, eya kubangela ukuba i-transformer igqithise kakhulu, inciphise umthamo wemveliso ye-transformer, ikhulise ingxolo ye-transformer, kwaye ibeka engozini ubomi benkonzo ye-transformer. .Umphumo wokubambelela we-harmonic currents unciphisa i-cross-section ye-conductor rhoqo kwaye ukwandisa ukulahleka komgca.I-voltage ye-Harmonic ichaphazela ukusebenza okuqhelekileyo kwezinye izixhobo zombane kwigridi, ibangela iimpazamo zokusebenza kwizixhobo zokulawula ngokuzenzekelayo kunye nokuqinisekiswa komlinganiselo ongachanekanga.I-voltage ye-Harmonic kunye ne-current ichaphazela ukusebenza okuqhelekileyo kwezixhobo zonxibelelwano ze-peripheral;ukugqithisa okwexeshana kunye nokugqithisa okwethutyana okubangelwa yi-harmonics yonakalisa i-insulation layer yomatshini kunye nezixhobo, okukhokelela kwiimpazamo zesigaba esithathu kunye nomonakalo kwi-transformers;amandla ombane we-harmonic kunye nesixa sangoku siya kubangela i-resonance yochungechunge oluyinxenye kunye ne-resonance efanayo kwigridi yamandla oluntu, okukhokelela kwiingozi ezinkulu.Kuyo yonke inkqubo yonikezelo lwamandla ombane, i-DC yokuqala ezinzile unikezelo lwamandla sisikweri samaza okutshintsha unikezelo lwamandla, olulingana nokuqokelelwa kwamaza e-sine kunye nemisinga ye-pulse ephezulu.Nangona i-post-stage circuit idinga isihluzo, i-harmonics ayinakuhluzwa ngokupheleleyo, eyona nto ibangela i-harmonics.
Amandla eHarmonic yesithando somlilo esiphakathi
Amandla emveliso ye-intermediate frequency induction furnace yahlukile, kwaye i-harmonics ehambelana nayo yahlukile:
1. Amandla endalo yesithando somlilo esiphakathi samandla aphezulu aphakathi kwe-0.8 kunye ne-0.85, imfuno yamandla esebenzayo inkulu, kwaye umxholo we-harmonic uphezulu.
2. Amandla endalo yesithando somlilo esiphakathi samandla aphantsi aphakathi kwe-0.88 kunye ne-0.92, kwaye imfuno yamandla esebenzayo incinci, kodwa umxholo we-harmonic uphezulu kakhulu.
3. I-harmonics yecala lomnatha yesithando somlilo esiphakathi ubukhulu becala yi-5, i-7 kunye ne-11.
Indlela yokulawula iHarmonic yesithando somlilo esiphakathi
Iifilitha ezilungelelanisiweyo ezi-5, 7, 11 kunye ne-13 ziyilwe.Phambi kwembuyekezo yesihluzi, into yamandla yomthengi we-intermediate frequency induction melting link yi-0.91.Emva kokuba izixhobo zembuyekezo zokucoca zifakwe ekusebenzeni, imbuyekezo ephezulu yi-0.98 capacitive.Emva kokuba isixhobo sembuyekezo yesihluzi sifakwe ekusebenzeni, ireyithi yokuguqula amandla ombane osebenzayo (ixabiso lilonke lokuphazamiseka kwe-harmonic) yi-2.02%.Ngokomgangatho wamandla omgangatho we-GB/GB/T 14549-1993, ixabiso le-voltage esebenzayo ye-harmonic (10KV) lingaphantsi kwe-4.0%.Emva kokwenza izihluzi kwi-5th, 7th, 11th kunye ne-13th ye-harmonic currents, izinga lokucoca limalunga ne-82∽84%, elidlula ixabiso lolawulo lomgangatho weshishini lenkampani yethu.Imbuyekezo isiphumo sesihluzo silungile.
