Loluphi uhlobo lonikezelo lwamandla oluphakathi olunokuhlangabezana neemfuno ze induction yokunyibilikisa iziko?

1 Iimfuno zamandla emveliso ye-intduction melting furnace ye-thyristor intermediate frequency power supply.

Amandla emveliso ye-thyristor intermediate frequency unikezelo lwamandla kufuneka ahlangabezane namandla aphezulu eziko lokunyibilikisa i-induction, kwaye amandla aphumayo anokulungiswa ngokulula. Oku kungenxa yokuba ubomi be-crucible ye-furnace yokunyibilika kwe-induction ngokuqhelekileyo malunga neshumi leziko kwaye zonakaliswe. I-oven crucible furnace kufuneka iphinde yakhiwe, kwaye emva kokuba i-oven entsha yomlilo yakhiwe, kufuneka kwenziwe i-oven ephantsi kwamandla. I-10% ngamaxesha aqhelekileyo de kube amandla alinganisiweyo. Ngaphezu koko, kwinkqubo yesithando somlilo, xa intlawulo iyancibilika, ukubunjwa kwentlawulo kufuneka kuhlolwe. Ngexesha lovavanyo, ukuze kuthintelwe intlawulo ekunyibilikeni kwaye ibilise ngamandla, unikezelo lwamandla olwenziwa ngamaza ombane aphakathi kufuneka lunciphise amandla aphumayo ukugcina intlawulo ishushu. Ngokujonga le meko ingentla, kuyafuneka ukuba i-thyristor intermediate frequency power supply inokulungelelaniswa ngokulula ukusuka kwi-20% -10% yamandla aphumayo. Isithando somlilo se-diathermic esisetyenziselwa ukubumba asinayo inkqubo yokubhaka.

2 Iimfuno zesiphumo sokuphindaphinda kweziko lokunyibilikisa induction for the thyristor intermediate frequency power supply.

Ubudlelwane phakathi kokusebenza kakuhle kombane kunye nokuphindaphinda kwesithando somlilo sokunyibilikisa sinxulumene. Ukuqala kwimpumelelo yombane, ukuvela kwamatyeli okuphuma kwe-thyristor intermediate frequency power supply inokumiselwa. Umzekelo, oku sikubiza ngokuba fo. I-inductor ngokwenene i-coil inductive, kwaye ukwenzela ukuhlawulela amandla asebenzayo e-coil, i-capacitor idibaniswe ngokufanayo kuzo zombini iziphelo zekhoyili, ezenza i-LC oscillating circuit. Xa imveliso frequency f of inverter thyristor ilingana yendalo oscillation frequency fo of induction melting loop loop, ngoko amandla factor loop ilingana 1. Amandla aphezulu iya kufumaneka kwi induction melting eziko. Kunokubonwa apha ngasentla ukuba i-oscillation frequency yendalo ye-loop inxulumene nexabiso le-L kunye ne-C. Ngokuqhelekileyo, ixabiso le-capacitor yembuyekezo ye-C lisisigxina, ngelixa i-inductance L iyatshintsha ngenxa yokutshintsha i-permeability coefficient ye-furnace material. I-permeability coefficient μ yentsimbi yesithando somlilo inkulu kakhulu, ngoko ke i-inductance L inkulu, kwaye xa ubushushu bentsimbi buphezulu kune-Curie point, i-coefficient yokulinganisa i-μ=1 yentsimbi, ngoko i-inductance L iyancipha, ngoko I-loop yokunyibilika kwe-oscillation yendalo iyakutshintsha ukusuka ezantsi ukuya phezulu. Ukuze wenze iziko lokunyibilikisa induction isoloko ifumana amandla aphezulu ngexesha lenkqubo yokunyibilikisa, oku kufuna ukuba imveliso frequency f ye thyristor intermediate frequency unikezelo lwamandla unokutshintsha kunye notshintsho fo, kwaye usoloko ugcine umkhondo ozenzekelayo rhoqo.

3 Ezinye iimfuno zobonelelo lwamandla ombane ophakathi kwe-thyristor.

Oku kungenxa yokuba xa intlawulo yesithando somlilo inyibilika, xa unikezelo lwamandla ombane ophakathi aluphumeleli, i-crucible iya konakaliswa kwiimeko ezinzima. Ke ngoko, unikezelo lwamandla ombane ophakathi kwe-thyristor luyafuneka ukuba lusebenze ngokuthembekileyo, kwaye kufuneka kwakhona lube nokhuseleko oluyimfuneko lokunciphisa umbane wangoku, ukhuseleko olugqithileyo kunye nolugqithileyo lwangoku, kunye nokucinywa kwamanzi. Ukhuseleko, kunye nezinye izixhobo zokhuseleko oluzenzekelayo. Ukongeza, kuyafuneka ukuba unikezelo lwamandla ombane ophakathi kwe-thyristor lunenqanaba eliphezulu lokuphumelela lokuqalisa, kwaye umsebenzi wokuqalisa wokuyeka kufuneka ube lula.
