Mhando mbiri dzekutanga dze electromagnetic casting

Kune maviri marudzi ekutanga emagetsi ekukanda, yakatwasuka uye yakachinjika, uye yakatwasuka yemagetsi kukanda inogona kupatsanurwa kuita kudhonza-kumusoro nekudhonza-pasi. Parizvino, iyo electromagnetic casting iyo yakaiswa mukugadzirwa kwemaindasitiri pamwero mukuru munyika yose yakaderedzwa. Naizvozvo, bhuku rino rinonyanya kuunza iyo electromagnetic yekukanda mudziyo weyakamira pasi-dhirowa aruminiyamu nemaaroyi ayo.

8. 1. 2. 1 Chigadzirwa chemagetsi uye hurongwa hwayo

Chishandiso chekupa magetsi chinhu chakakosha chekukanda magetsi, kusanganisira yepakati frequency jenareta seti kana thyristor yepakati frequency magetsi magetsi. Iyo yaimbova Soviet Union, Hungary, Czech Republic, Germany nedzimwe nyika dzeEurope dzakatora epakati frequency jenareta seti mukutanga, uye seti yemajenareta seti inogona kungokanda ingot imwe chete. Mushure memakore ekuma1970, nyika dzakaita seSwitzerland neUnited States dzakashandisa thyristor yepakati frequency magetsi emagetsi kune tekinoroji yekukanda tekinoroji, uye seti yemagetsi inogona kukanda akawanda ingots. Iyo thyristor yepakati frequency magetsi magetsi ane akawanda mabhenefiti pamusoro pepakati frequency jenareta seti, saka inoshandiswa zvakanyanya.

Iyo musimboti weiyo electromagnetic casting simba system inoratidzwa muMufananidzo 8-6.

Mufananidzo 8-6 Schematic diagram yemagetsi ekupa system

1-square aluminium ingot; 2-mold induction coil; 3-yepakati frequency transformer; 4-mubhadharo capacitor;

5-Inverter circuit; 6-Smoothing inductor; 7-Kugadzirisa dunhu; 8-Matatu-chikamu AC ikozvino

The thyristor intermediate frequency power supply chinhu chinoshandura matatu-phase simba frequency alternating current kuita yepakati frequency alternating current. Iyo inoshandisa AC-DC-AC frequency shanduko yedunhu, iyo inoratidzwa nekuve neinotemerwa yepakati link. Kuburikidza neiyo rectifier wedunhu, iyo simba frequency AC simba rinotanga kushandurwa kuita DC simba, uye ipapo iyo DC simba inoshandurwa kuita AC simba ne frequency ye / kuburikidza neinoshandura dunhu. Iyo thyristor yepakati frequency magetsi magetsi ine zvakanakira dunhu rakareruka, nyore kugadzirisa, kushanda kwakavimbika, uye kugona pamusoro pe90%. Zvishandiso zvine hunyanzvi hwakasiyana zvine zvishoma zvakasiyana kudzora zvishwe uye zvimiro zvakasiyana, asi musimboti wakafanana.
