Musiyano uripo pakati pehuni yekupinza uye cupola:

1. Iyo cupola chinhu chakakosha chekunyungudutsa simbi yakakandwa mukugadzira kugadzirwa. Simbi yakaumbwa inonyungudutswa kuita simbi yakanyungudutswa yodirwa muforoma yejecha kuti itonhodze uye yozobudiswa kuti iwane kukanda. Iyo cupola ndeye yakamira cylindrical smelting furnace, iyo yakakamurwa kuita choto chemberi uye nechekumashure. Iyo forehearth yakakamurwazve kuita gomba repombi, gomba repombi yeslag, nzvimbo yepamberi yevhavha yechoto uye bhiriji. Choto cheshure chakakamurwa kuita zvikamu zvitatu, choto chepamusoro, choto chechiuno uye choto. Choto chechiuno chinoparadzaniswa kubva kune inopisa kuputika chubhu, yakavharwa mushure mekugadzirisa choto, uye yakavharwa nematope. Pachoto chepamusoro pane kupisa kupisa. Inonyanya kushandiswa kugadzirwa kwesimbi castings uye zvakare inoshandiswa kugadzira simbi nevashanduri. Nekuti iyo cheto yepamusoro inovhura kumusoro, inonzi cupola.

2. Induction furnace isimba rekupa simba rinoshandura 50HZ simba frequency alternating current kuva intermediate frequency (pamusoro pe300HZ kusvika 20K HZ). Iyo inoshandura matatu-chikamu simba frequency alternating ikozvino kuita yakananga ikozvino mushure mekugadzirisa, uyezve inoshandura yakananga ikozvino kuita inogadziriswa yepakati frequency ikozvino. Iyo yepakati frequency alternating ikozvino inoyerera kuburikidza necapacitor uye induction coil inopihwa kuti ibudise yakakwirira-density magineti mitsara yesimba mune induction coil, uye simbi yesimbi iri muinduction coil inochekwa, uye hombe eddy ikozvino inogadzirwa mukati simbi zvinhu.
