Vanhu vazhinji vanofarira kupfeka zvishongo zvesimbi zvakakosha sezvishongo, zvishongo, mhete, mhete, nezvimwewo. Masimbi makuru anoshandiswa muzvishongo igoridhe neplatinamu.
Danho rekutanga mukugadzira zvishongo zvesimbi zvakakosha kunyungudisa simbi yakakosha kuburikidza nechoto chinonyunguduka.Kune marudzi akawanda ehuni dzekunyungudutsa pamusika.Tichasangana nemamwe matambudziko pakusarudza choto chinonyunguduka.We don't kuziva kuti ndeipi choto chinonyunguduka chakanyanya kukodzera kune yedu simbi zvinhu zvinonyunguduka zvinodiwa.
Muindasitiri yezvishongo, zvakajairika kushandisa induction furnaces kunyungudutsa simbi.Saka kana iwe uchida kusarudza achoto chokunyungudutsa, iwe unofanirwa kubhadhara kune zvinotevera pfungwa:
Muchokwadi, induction yekunyungudutsa mavira anowanzo shandiswa mune yepakati frequency uye yakakwirira frequency emagetsi mavhiri.Iyo yakanyanya tembiricha yepakati frequency yekunyungudutsa choto ndeye 2600°C. Iyo yakanyanya tembiricha yehuni yehuni yakakura ndeye 1600°C. Saka kana uri kutsvaga kutenga chitofu chekupinza, zvinoenderana nesimbi yaunoda kunyungudika.
Nzvimbo yekunyunguduka kwegoridhe i1064°C, nzvimbo yakanyunguduka yeplatinamu ndeye 1768°C, uye nzvimbo yakanyunguduka yesirivha i961°C. Saka kana ukanyungudutsa goridhe nesirivha, unofanira kushandisa high frequency kunyunguduka choto, kwete yepakati frequency choto.Kana kupisa kwekunyunguduka kwakanyanyisa, kunokonzera kuchinja kwehutano hwesimbi.Simbi yakanyungudutswa inogona kusvibiswa.
Nenzira, pakusarudza choto chinonyunguduka, tinofanirawo kubhadhara kune rudzi rwecrucible.Kune marudzi maviri emakororo: graphite crucible uye quartz crucible.Zvichienderana nekunyunguduka kwekushisa, magirafu crucibles anoshandiswa mune yakakwirira frequency furnaces.Uye quartz crucible yepakati frequency choto.Quartz inoshingirira kune tembiricha yakanyanya kupfuura graphite.Izvo zvinofanirwa kucherechedzwa kuti sirivha inogona kushandiswa chete mu graphite crucibles, kwete mu quartz crucibles.Nokuti sirivha inopindirana ne quartz uye inodzivirira sirivha kubva pakunyunguduka zvachose, inobva yanamatira kune crucible uye inokonzera kurasikirwa kukuru.
