Basic classification ye induction furnace

Induction furnaces can be divided into high frequency furnaces, intermediate frequency furnaces and industrial frequency furnaces according to the power frequency; according to the process purpose, they can be divided into melting furnaces, heating furnaces, heat treatment equipment and welding equipment; according to their structure, transmission mode, etc. sort. Commonly used induction furnaces are habitually grouped into hearted induction melting furnaces, induction melting furnaces, vacuum induction melting furnaces, induction hardening equipment and induction head thermal equipment, etc. The name of the smelting furnace is relative to the induction smelting furnace. The molten metal is contained in a crucible, so it is also called a crucible furnace. This type of furnace is mainly used for smelting and heat preservation of special steel, cast iron, non-ferrous metals and their alloys. The coreless furnace has many advantages such as high melting temperature, less impurity pollution, uniform alloy composition, and good working conditions. Compared with the cored furnace, the coreless furnace is easier to start and change the metal varieties, and it is more flexible to use, but its electric and thermal efficiency is far lower than that of the cored furnace. Due to the low surface temperature of the coreless furnace, it is not conducive to smelting that requires high-temperature slagging processes.

Iyo yekunyunguduka yevira yakakamurwa kuita yakakwirira frequency, yepakati frequency uye simba frequency.

(1) High-frequency kunyunguduka choto

Hunhu hwechoto chepamusoro-soro kazhinji huri pasi pe50 kg, iyo yakakodzera kunyungudutsa simbi yakakosha uye alloys akakosha mumarabhoritari uye kugadzirwa-diki.

(2) Yepakati frequency kunyunguduka choto

Kugona uye simba repakati frequency smelting furnace yakakura kupfuura iyo yepamusoro frequency furnace. Inonyanya kushandiswa kunyungudutsa masimbi akakosha, magineti alloys uye alloys emhangura. Nekuti iyi mhando yevira inoda inodhura frequency shanduko yemidziyo, yakachinjirwa kune yemagetsi frequency coreless choto mune mamwe mahombe ekugonesa. Nekudaro, zvichienzaniswa neiyo maindasitiri frequency furnace, iyo yepakati frequency furnace inewo yayo yakasarudzika maficha. Semuenzaniso, kuchoto chehuni hwakafanana, simba rekuisa repakati frequency furnace yakakura kupfuura iyo yeindasitiri frequency furnace, saka kukurumidza kunyungudika kunokurumidza. Iyo yepakati frequency choto haidi kusimudza choto chevira kana choto chinotonhora chatanga kunyungudika. Iyo simbi yakanyungudutswa inogona kudururwa kunze, saka kushandiswa kwakanyanya. uyezve, mhinduro mune yepakati frequency kunyungudutsa vira ine yakareruka scour pane crucible, iyo inobatsira kune yevira yekubikira. Naizvozvo, mushure mekuvandudzwa kwesimba repamusoro-soro uye rakachipa repakati frequency magetsi emagetsi, epakati frequency furnaces achiri kuvimbisa.

(3) Power frequency kunyungudutsa choto

Iyo yemagetsi frequency yekunyungudutsa choto ndiyo yazvino uye inokurumidza kukura pakati pemavira akawanda ekunyungudutsa. Inonyanya kushandiswa kunyungudutswa kwesimbi yakakandwa uye simbi, kunyanya yakakwirira-simba rakakandwa simbi uye alloy cast iron, pamwe chete nekupisa, kuchengetedza kupisa uye kugadziriswa kwekugadzirisa kwekugadzirisa kwesimbi yakakandwa; uyezve, inoshandiswawo pakunyungudutsa simbi dzisina ferrous dzakadai semhangura nealuminium nema alloys adzo. Kana huni hwehuni huri hudiki, hazvisi zvehupfumi kushandisa simba remagetsi. Tora simbi yakakandwa semuenzaniso. Kana huwandu huri pasi pe750 kg, kushanda kwemagetsi kunoderera zvakanyanya. Vacuum induction melting furnace inoshandiswa kunyungudutsa ma alloys anodzivirira kupisa, magineti alloys, magetsi alloys uye simbi dzakasimba. Hunhu hwemhando iyi yevira ndeyekuti zviri nyore kudzora tembiricha yevira, vacuum degree uye nguva yekunyunguduka panguva yekunyungudika, saka degassing yemuchaji inogona kunge yakakwana. Pamusoro pezvo, huwandu hwekuwedzera hwealloy zvinhu hunogona zvakare kudzorwa nemazvo, saka ivira rakakodzera kunyungudutsa maaloyi asingadzivirirwe uye maaloyi chaiwo ane zvinhu zvinoshanda senge aluminium uye titanium.
