Iintlobo ezimbini ezisisiseko zokuphosa i-electromagnetic

Kukho iindidi ezimbini ezisisiseko zokuphosa i-electromagnetic casting, ethe nkqo kunye nethe tyaba, kwaye ukuphosa okuthe nkqo kwe-electromagnetic kunokohlulwa kube kukutsalwa kunye nokutsalwa phantsi. Okwangoku, ukuphosa kwe-electromagnetic okufakwe kwimveliso yemizi-mveliso kwinqanaba elikhulu kwihlabathi lonke kucatshulwe phantsi. Ke ngoko, le ncwadi yazisa ubukhulu becala isixhobo sokuphosa sombane we-aluminiyam esezantsi ethe nkqo kunye neealloyi zayo.

8. 1. 2. 1 Isixhobo sokubonelela ngombane kunye nenkqubo yayo

Isixhobo sonikezelo lwamandla sisixhobo esibalulekileyo sokuphosa i-electromagnetic, kubandakanywa iseti yejeneretha ephakathi okanye i-thyristor intermediate frequency frequency. Owayesakuba yiSoviet Union, iHungary, iRiphabliki yaseCzech, iJamani kunye namanye amazwe aseYurophu amkela iiseti zejenereyitha zamaxesha aphakathi kwinqanaba lokuqala, kwaye iseti yeeseti zejenereyitha zinokuphosa ingot enye kuphela. Emva kweminyaka yee-1970s, amazwe anjengeSwitzerland kunye neUnited States asebenzisa amandla ombane aphakathi kwe-thyristor kwitekhnoloji yokuphosa ye-electromagnetic, kwaye iseti yezibonelelo zombane zinokuphosa ii-ingots ezininzi. Unikezelo lwamandla oluphakathi lwe-thyristor luneenzuzo ezininzi ngaphezu kweesethi zejeneretha eziphakathi, ngoko ke zisetyenziswa ngokubanzi.

Umgaqo wenkqubo yamandla e-electromagnetic casting iboniswe kuMfanekiso 8-6.

Umzobo 8-6 umzobo weSchematic wenkqubo yokubonelela ngombane

I-1-square aluminium ingot; I-2-mold induction coil; I-3-intermediate frequency transformer; I-4-capacitor yembuyekezo;

5-I-Inverter circuit; 6-Inductor egudileyo; 7-Ukulungiswa kwesekethe; I-8-Isigaba sesithathu se-AC okwangoku

I-thyristor intermediate frequency power supply sisixhobo esiguqula i-frequency yesigaba sesithathu samandla atshintshayo akhoyo abe yi-intermediate frequency alternating current. Isebenzisa i-AC-DC-AC ye-frequency conversion circuit, ebonakala ngokuba ne-tributary intermediate link. Ngokusebenzisa isekethe yokuhlaziya, amandla ombane we-AC aguqulwa kuqala abe ngamandla e-DC, emva koko amandla eDC aguqulelwe kumandla e-AC kunye nokuphindaphinda kwe / ngesekethe yokuguqula. Unikezelo lwamandla ombane ophakathi kwe-thyristor lunezibonelelo zesekethe elula, ukulungisa iimpazamo, ukusebenza okuthembekileyo, kunye nokusebenza kakuhle okungaphezulu kwe-90%. Izixhobo ezinobuchule obahlukeneyo zineendlela ezahlukeneyo zokulawula iilophu kunye nezakhiwo ezahlukeneyo, kodwa umgaqo uyafana.
