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 i-induction melting furnace njengomzekelo. Ukusukela ukuba inkampani yaseSwitzerland yeBBC iphuhlise ngempumelelo unikezelo lwamandla lokuqala lwe-thyristor oluphakathi lokunyibilika ngo-1966, amazwe amakhulu oshishino aye azisa ngokulandelelanayo le mveliso, eyathi kungekudala yathatha indawo yeseti yesiqhelo ephakathi kombane-jenereyitha. Ngenxa yokuba unikezelo lwamandla ombane ophakathi kwe-thyristor lusebenza kakuhle kakhulu, umjikelo omfutshane wokwenza, ufakelo olulula, kunye nolawulo olulula oluzenzekelayo, uluhlu lwesicelo lwayo lugubungela iindawo ezahlukeneyo zemveliso yemizi-mveliso efana nokunyibilikisa, i-diathermy, ukucima, i-sintering, kunye ne-brazing. Okwangoku, kubekho impumelelo ebalulekileyo kwinqanaba lobugcisa kunye nenqanaba lezixhobo zesithando somlilo sokunyibilikisa samazwe ngamazwe, ngakumbi ngolu hlobo lulandelayo:

Umthamo wesithando somlilo uvela kumncinci ukuya kumakhulu, isithando somlilo esiphezulu sinokufikelela kwi-30t, kwaye isithando somlilo sinokufikelela kwi-40-50t;

Uluhlu lwamandla ukusuka kumncinci ukuya kumakhulu, kubandakanya 1000kW, 5000kW, 8000kW, 10000kW, 12000kW, njl.;

Ukusuka kunikezelo lwamandla okuqhuba isithando sokunyibilikisa induction ukuphuhlisa enye ukuya ezimbini (enye yokunyibilikisa, ukugcinwa kobushushu omnye, uthotho lwesekethe), okanye nokuba “enye ukuya kwezintathu”;

I-furnace yokunyibilikisa i-induction ihambelana nokucocwa ngaphandle kwe-furnace yentsimbi okanye i-AOD yomlilo ukufezekisa iziphumo ezilungileyo;

Ukuphumelela okubalulekileyo kwisekethe yonikezelo lwamandla, ukusuka kwisigaba sesithathu se-6-pulse, isigaba sesithandathu se-12-pulse ukuya kwisigaba seshumi elinesibini se-24-pulse, ukuthembeka kwesekethe ye-thyristor kuphezulu, kunye nesixhobo sokubonelela ngombane sinokudityaniswa nonyango. ii-harmonics ezikumgangatho ophezulu;

Umgangatho wokulawula uphuculwe, kwaye inkqubo ye-PLC ingasetyenziselwa ngokufanelekileyo ukulawula ngokufanelekileyo iiparitha zombane zesithando somlilo;

Umzimba oyintloko kunye nezixhobo ezincedisayo ziphelele ngakumbi.
