Outstanding performance of ukuchithwa kwesithando somlilo

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.

Thatha isithando somlilo se-induction njengesibonelo. Kusukela inkampani ye-BBC yaseSwitzerland ithuthukise ngempumelelo ugesi wokuqala we-thyristor ophakathi nendawo wokuncibilika ngo-1966, amazwe amakhulu ezimboni aye wethula ngokulandelanayo lo mkhiqizo, osheshe wathatha indawo yesethi ye-generator kagesi ephakathi nendawo. Ngenxa yokuthi i-thyristor intermediate frequency power supply isebenza kahle kakhulu, umjikelezo omfushane wokukhiqiza, ukufakwa okulula, nokulawula okuzenzakalelayo okulula, uhla lwayo lokusebenza luhlanganisa izinkambu ezihlukahlukene zokukhiqiza zezimboni ezifana nokuncibilika, i-diathermy, i-quenching, i-sintering, ne-brazing. Njengamanje, kube khona impumelelo ebalulekile ezingeni lobuchwepheshe kanye nezisetshenziswa zesithando somlilo esincibilikisa umhlaba wonke, ikakhulukazi ngale ndlela elandelayo:

Umthamo wesithando somlilo usuka omncane kuya omkhulu, isithando somlilo esincibilikayo esiphezulu singafinyelela ku-30t, futhi isithando somlilo esibambayo singafinyelela ku-40-50t;

Amandla asukela kokuncane kuye kwamakhulu, ahlanganisa 1000kW, 5000kW, 8000kW, 10000kW, 12000kW, njll.;

Ukusuka kugesi wokushayela isithando somlilo esincibilikayo sokungeniswa ukuze kuthuthukiswe okukodwa kuya kokubili (ukuncibilika okukodwa, ukulondolozwa kokushisa okukodwa, isekethe yochungechunge), noma ngisho “okukodwa kuya kokuthathu”;

Isithando somlilo esincibilikayo sokungeniswa sihambisana nokucwengwa ngaphandle kwesithando somlilo wensimbi noma i-AOD ukuze kuzuzwe imiphumela emihle;

Ukuphumelela okubalulekile kumjikelezo wokuphakelwa kwamandla, kusukela kusigaba sesithathu se-6-pulse, isigaba sesithupha se-12-pulse kuya kwesigaba seshumi nambili se-24-pulse, ukuthembeka kwesekethe ye-thyristor kuphezulu, futhi idivayisi yokuhlinzeka amandla ingavumelaniswa nokwelashwa. ama-harmonics aphezulu;

Izinga lokulawula liyathuthukiswa, futhi uhlelo lwe-PLC lungasetshenziswa kalula ukulawula ngokuphumelelayo imingcele kagesi yesithando somlilo;

Umzimba oyinhloko kanye nezinto ezisizayo ziphelele kakhulu.
