Outstanding performance of ho qhibiliha ha sebōpi

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.

Nka mohlala oa sebōpi sa ho qhibiliha sa induction. Ho tloha ha k’hamphani ea Switzerland ea BBC e atlehile ho hlahisa motlakase oa pele oa thyristor intermediate frequency power for induction melting ka 1966, linaha tse kholo tsa indasteri li hlahisitse sehlahisoa sena ka tatellano, se ileng sa nkela sebaka sa setso sa motlakase oa motlakase oa motlakase. Hobane phepelo ea motlakase ea maqhubu a mahareng a thyristor e na le ts’ebetso e phahameng haholo, potoloho e khuts’oane ea tlhahiso, ts’ebetso e bonolo, le taolo e bonolo ea othomathike, sebaka sa eona sa ts’ebeliso se akaretsa likarolo tse fapaneng tsa tlhahiso ea indasteri joalo ka smelting, diathermy, quenching, sintering le brazing. Hajoale, ho bile le likhatelopele tsa bohlokoa boemong ba tekheniki le boemo ba lisebelisoa tsa sebōpi sa machaba sa ho qhibilihisa, haholo-holo ka tsela e latelang:
