Isithando sokufakelwa sisixhobo esisebenzisa umgaqo wokungeniswa kwentsimi ye-electromagnetic ukuguqula amandla ombane abe ngamandla obushushu ukutshisa kunye nokunyibilikisa intlawulo yesinyithi. Ngokwesakhiwo, yahlulwe yangamacandelo amabini: isithando somlilo esingundoqo kunye ne-coreless induction
Isithando somlilo se-coreless induction sinenzuzo yokusebenza okuphezulu, ukonga amandla, ungcoliseko oluphantsi, uhlengahlengiso olulula lokubunjwa, ukulawulwa lula kwe-atmospheric, amandla okufudumeza okuqinileyo, kunye nokusebenza kancinci. I-furnace induction yahlula-hlulwe ibe: isithando somlilo sokuphindaphinda amandla (ngaphakathi kwe-50Hz); i-furnace ye-frequency induction ephakathi (50Hz-10000Hz) kunye ne-furnace induction induction ephezulu (ngaphezu kwe-10000Hz). Kwiminyaka yakutshanje, kunye nophuhliso kunye nokuthembeka ukuphuculwa unikezelo lwamandla aphezulu-amandla thyristor variable frequency, iziko intermediate frequency ngokuthe ngcembe ithathe indawo eziko amandla frequency. Xa kuthelekiswa nesithando somlilo samaza ombane, isithando somlilo esiphakathi sinokusebenza kakuhle kwe-thermal kunye nokusebenza kakuhle kombane, ixesha elifutshane lokunyibilika, ukusetyenziswa kwamandla aphantsi, kunye nokuphunyezwa lula. iingenelo zokuzenzekelayo. Ukongezelela, i-furnace induction iphuhlisa kwicala lomthamo omkhulu kunye namandla aphezulu, aneemfuno eziphezulu zezinto eziphikisayo.
I-refractory lining yinto ebalulekileyo emisela ukuveliswa kwesithando somlilo, ukuphosa umgangatho kunye nokhuseleko kunye nokuthembeka kwemveliso kunye nokusebenza. Ukufumana i-refractory lining enomgangatho omhle kunye nobomi benkonzo ende, kufuneka siqale siqonde imiqathango yokusetyenziswa: (1) Ubuninzi be-refractory lining buphezulu. I-Thin, i-gradient yokushisa ye-lining inkulu; (2) Ukushukuma kombane wesinyithi esinyibilikisiweyo esisezikweni kubangela ukhukuliseko olungoomatshini lwentambo echasayo; (3) Umgca we-refractory ucinywa ngokuphindaphindiweyo kwaye uchaphazeleke ngokushushu.
Ngoko ke, izinto ezikhethiweyo ezichaseneyo kufuneka zibe: ngokwaneleyo ukuchasana okuphezulu kunye nokushisa okuthambileyo phantsi komthwalo; uzinzo oluhle lokutshatyalaliswa kwe-thermal; akukho ukuphendula kweekhemikhali ngeentsimbi kunye ne-slag; amandla athile omatshini wobushushu obuphezulu; ukugquma kakuhle kunye ne-Insulation; ukwakhiwa kakuhle, ukuxinana okuphezulu kokuzalisa, ukuthambisa okulula, ukugcinwa okufanelekileyo; izibonelelo ezininzi zezinto eziluhlaza, amaxabiso aphantsi, njl. Uyilo lwesithando somlilo esikhulu se-frequency crucible induction luhlala luqala ukusuka ekukhethweni kwezinto eziphikisayo kunye novavanyo lokulinganisa lwe-furnace lining. Kwimeko nayiphi na into, ukukhethwa kweerefractories ze-furnace lining kusekelwe ekusebenziseni kunye noqoqosho lwesithando somlilo. Ngenjongo yokudibanisa okuqinileyo kwizixhobo zombane, i-thinner ye-lining thickness, kungcono ngaphandle kokuchaphazela ubomi benkonzo.
