Medium Frequency Melting Electric Furnace
Medium frequency kunyunguduka choto chemagetsiinowanzoshandiswa mumunda weimwe simbi yekuchenesa zvinhu, rudzi urwu rwemedium frequency kunyunguduka choto chemagetsiiri nyore kwazvo kushandura, iko iko kushanda kuri nyore kwazvo, chengetedzo, ipapo nemunhu wese uye ini ndinokwanisa maitiro ese epakati frequency kunyungudutsa choto chemagetsi uye zvakanakira nekuipira kweiyo yakadzama sumo iyo.
A, Melting electric furnace
Choto chemagetsi kunyungudukaelectromagnetic simba rekupisa sosi yenzira yekunyungudutsa yezita remubatanidzwa.Choto chemagetsi kunyunguduka, zviri nani grey cast iron uye grey iron inonyungudika, kana iyo yakanyunguduka ichizowedzera, inogona kusimudzira kushandiswa kweakawanda echoto madziro ekupedzisira.Zvinoenderana neiyo nzira yekudziya yakakamurwa kuita yemagetsi ega kunyunguduka, yemagetsi arc resistor compound kuvaka kunyunguduka, magineti induction kunyungudika.Kazhinji inoshandiswa kune isiri-ferrous simbi uye aruminiyamu alloy, tini, nickel uye zvimwe simbi zvinhu kunatsa.
Chepiri,Tiye yose process
Choto chemagetsimagetsi nema electrode matatu kuti ape matatu-phase alternating current, kudzoreredza kunyunguduka kupisa kunodiwa ne electrode uye slag inobata arc discharge uye kuyerera kwemagetsi maererano nechaji uye marasha emarasha akakonzerwa, ndiko kuti, kupisa mukati mechimiro chemukati chechaji chakakonzerwa. , saka kunyungudika kwechaji uye kuchinja kwemakemikari mukati mehutano hwemukati hwekuchaja kunoitwa, saka, kunyunguduka kwechoto chemagetsiis a passivation reaction and slagging panguva imwe chete kuti ibudirire, pedyo ne electrode yemarasha ash, nokuti tembiricha Iyo dota iri pedyo ne electrode, nekuda kwekukwira kwekushisa uye slag mukuratidzira kwekugadzirwa kwemhute kuderedza hukama hwayo. uye kumusoro kugadziridzwa pamwe chete ne electrode, kumusoro uye yobva yapararira kune yakatenderedza nhanho, nepo yakaderera tembiricha yechoto yekuchaji inogayiwa kuti itore simba rinopisa remadota anopisa uye kunyunguduka, yakanyungudutsa muchoto wekuchaja uye yakaderedza tembiricha. yedota rakavhenganiswa pamwe chete, nekuda kwehuwandu hwayo hwehama yakawedzera uye ichidzika, kana ichidzika kusvika pakadzika yakadzika ye electrode inoiswa, chikamu chehutano hwekufamba kune electrode uye inoramba ichidzokororwa chikamu, uye chikamu chakasara chiri. zvakare nheyo inonyura kusvika kumagumo emurwi, uye pamwe chete nechoto chechoto pasi penzvimbo inonyunguduka yekufamba kwemazinga, saka iyo yakawanda inonyunguduka ichidzika muzasi yakanyarara yakanyarara slag layer, uye kuita slag uye iyo yakazara. chinangwa chekuparadzana kunze.
Chechitatu, zvakanakira nezvazvakaipira
Hunhu hwechoto chemagetsikunyungudika ndiko:
(1) fusion tembiricha iri nyore kugadzirisa, uye inogona kuwana tembiricha yepamusoro, inogona kugadzirisa mbishi zvinhu zvine mamwe silicides, marasha emarasha ari nyore kupisa zvakanyanya, anobatsira kudzoreredza ferric tetroxide, slag ine yakaderera huwandu hwezvinhu zvakakosha zvesimbi. .
(2) choto chinopa gasi vhoriyamu idiki, iyo huruva yemukati yakaderera.Inzwi remagetsi echoto chisimbiso, inogona kuwedzera kukosha kweiyo soot sulfur dioxide, uye inogona kushandiswa.
(3) Hunhu hwezvakagadzirwa muhukuru hwehukuru, hunogona kugadzirisa zvimwe zvinhu zvakasiyana, kudzorera zvinhu.
(4) Zviri nyore kwazvo kunyengedza, inoenderana nebasa chairo, nyore kupedzisa nyanzvi uye otomatiki tekinoroji.
(5) yakaderera gasi tembiricha, kupisa kwekushandisa kwe45% ~ 60%, iyo yekutenderera honi uye chikamu chechoto chemoto inogona kuvakwa neyakachipa refractory yevhu zvidhinha madziro.
