I-Induction furnace iyithuluzi elisebenzisa umgomo wokungeniswa kwensimu kagesi ukuguqula amandla kagesi abe amandla okushisa ukuze kushise futhi kuncibilike ukushaja kwensimbi. Ngokwesakhiwo, sihlukaniswe izigaba ezimbili: isithando somlilo esiyisisekelo nesithando somlilo esingenasisekelo.
I-coreless induction furnace inezinzuzo zokusebenza kahle kakhulu, ukonga amandla, ukungcoliswa okuphansi, ukulungiswa okulula kokwakheka, ukulawula okulula komkhathi, amandla okushisa aqinile, nokusebenza ngezikhathi ezithile. Isithando somlilo se-induction sihlukaniswe: isithando somlilo se-frequency induction (ngaphakathi kwe-50Hz); isithando somlilo sokungenisa imvamisa emaphakathi (50Hz-10000Hz) kanye nesithando somlilo sokungeniswa imvamisa ephezulu (ngaphezu kuka-10000Hz). Eminyakeni yamuva nje, ngokuthuthukiswa nokuthembeka kokuthuthukiswa kwamandla aphezulu we-thyristor variable frequency power supply, isithando somlilo esiphakathi siye sashintsha kancane kancane isithando somlilo samandla. Uma kuqhathaniswa nesithando somlilo sefrikhwensi yamandla, isithando somlilo esiphakathi sinokusebenza kahle kokushisa okuphezulu nokusebenza kahle kukagesi, isikhathi esifushane sokuncibilika, ukusetshenziswa kwamandla okuphansi, nokusebenzisa kalula. izinzuzo ezizenzakalelayo. Ngaphezu kwalokho, isithando somlilo sokungeniswa sithuthuka ngendlela yomthamo omkhulu namandla aphezulu, anezidingo eziphakeme zezinto eziphikisayo.
I-Refractory lining iyisici esibalulekile esinquma ukuphuma kwesithando somlilo sokungeniswa, ikhwalithi yokusakaza nokuphepha nokuthembeka kokukhiqiza nokusebenza. Ukuthola ulayini ophikisayo onekhwalithi enhle nempilo ende yesevisi, kufanele siqale siqonde imibandela yokusebenzisa: (1) Ugqinsi lolwelwesi oluphikisayo luphakeme uma kuqhathaniswa. Izacile, izinga lokushisa lolwelwesi likhulu; (2) Ukunyakaziswa kukazibuthe kwensimbi encibilikisiwe esithandweni kubangela ukuguguleka kolwelwesi oluphikisayo; (3) I-refractory lining icinywa ngokuphindaphindiwe futhi ithinteke ngokushisa.
Ngakho-ke, izinto ezikhethiwe eziphikisayo kufanele zibe: ukuqina okuphezulu ngokwanele nokushisa okuthambile ngaphansi komthwalo; ukuzinza okuhle kokushaqeka okushisayo; akukho ukusabela kwamakhemikhali ngezinsimbi kanye ne-slag; amandla athile omshini wokushisa okuphezulu; I-insulation enhle kanye ne-insulation; ukwakhiwa okuhle, ukuminyana kokugcwalisa okuphezulu, i-sintering elula, ukugcinwa okulula; izinsiza eziningi zezinto zokusetshenziswa eziphikisayo, amanani aphansi, njll. Ukuthuthukiswa kwesithando somlilo sokungeniswa kuhlobene eduze nenqubekelaphambili yezobuchwepheshe yezinto eziphikisayo. Idizayini yesithando somlilo esifakwa imvamisa enkulu ye-crucible induction ngokuvamile iqala kusukela ekukhethweni kwezinto eziphikisayo kanye nokuhlolwa kokulingisa kolayini lwesithando somlilo. Kunoma yikuphi, ukukhethwa kwama-refractories okufakwa kwesithando somlilo kusekelwe ekusetshenzisweni nasezomnotho kwesithando somlilo. Ngenhloso yokuhlanganisa okuqinile ezintweni zikagesi, ukushuba komugqa kube mncane, kungcono ngaphandle kokuthinta impilo yesevisi.
