Outstanding performance of kudonhedzwa kunyorera vira

The frequency of the power supply used by the induction melting furnace is in the range of 150-10000Hz, and its common frequency is 150-2500Hz. The induction melting furnace is now widely used in the production of steel and other non-ferrous alloys, and is also widely used in the foundry industry.

Tora induction yekunyungudika choto semuenzaniso. Sezvo kambani yeSwiss BBC yakabudirira kugadzira yekutanga thyristor yepakati frequency magetsi ekunyungudika muna 1966, nyika huru dzemaindasitiri dzakaunza chigadzirwa ichi zvakatevedzana, icho chakakurumidza kutsiva chekare chepakati frequency magetsi-jenareta. Nekuti iyo thyristor yepakati frequency magetsi magetsi ane hunyanzvi hwekuita, kupfupika kwekugadzira kutenderera, kuisirwa nyore, uye nyore otomatiki kudzora, huwandu hwayo hwekushandisa hunovhara dzakasiyana siyana dzekugadzira maindasitiri senge kunyungudutsa, diathermy, kudzima, sintering, uye brazing. Parizvino, kwave nekubudirira kwakakosha padanho rehunyanzvi uye nhanho yemidziyo yepasirese induction melting virace, kunyanya sezvinotevera:

Huto hwehuni hunobva kudiki kusvika kuhombe, iyo yakanyanyisa kunyunguduka choto inogona kusvika 30t, uye choto chekubata chinogona kusvika 40-50t;

Simba rinobva padiki kusvika kune rakakura, kusanganisira 1000kW, 5000kW, 8000kW, 10000kW, 12000kW, nezvimwewo;

Kubva pamagetsi ekufambisa muchoto wekunyungudutsa induction kuti ugadzire imwe kusvika mbiri (imwe kunyunguduka, imwe kuchengetedza kupisa, nhepfenyuro yedunhu), kana kunyange “imwe kusvika kumatatu”;

Iyo induction yakanyunguduka furnace inofananidzwa nekunatswa kwekunze kwesimbi kana AOD vira kuti uwane mhedzisiro yakanaka;

Kubudirira kwakakosha mumagetsi emagetsi, kubva kunhatu-chikamu 6-pulse, matanhatu-chikamu 12-pulse kusvika gumi nembiri-chikamu 24-pulse, kuvimbika kweiyo thyristor wedunhu kwakakwira, uye mudziyo wekupa magetsi unogona kuwiriraniswa nekurapa. ye-high-order harmonics;

Iyo yekudzora nhanho inovandudzwa, uye iyo PLC system inogona kushandiswa zviri nyore kudzora zvinobudirira ma paramita emagetsi echoto;

Muviri mukuru uye midziyo yekubatsira yakawedzera kukwana.
