Metal kudziyisa choto

Sezvinoratidzwa nezita racho, simbi yekudziisa choto choto chinopisa simbi uye chiri cheiyo thermal processing industry. Masimbi ekudziisa ane kupisa kwemarasha, kupisa mafuta, kupisa gasi uye kupisa kwemagetsi. Nekuda kwezvinodiwa zvekuchengetedza simba uye kuchengetedzwa kwezvakatipoteredza, magetsi ekupisa simbi yekupisa mafito ave akakurumbira mumakore achangopfuura. 1. Kupisa musimboti wemagetsi kupisa simbi yekupisa vira

1. Magetsi ekudziisa simbi yekudziya mavira akakamurwa kuita simbi yekudziya kupisa mavira uye induction simbi yekupisa mavira.

1. Kupikisa rudzi rwesimbi inopisa choto inotora nzira yekudzivirira waya yekupisa. Kana iyo yazvino ichiyerera kuburikidza nekondukita, nekuti chero conductor inopesana, simba remagetsi rinorasika mune conductor uye rinoshandurwa kuita kupisa simba, maererano nemutemo waJoule Lenz:

Q=0.24I2 Rt Q-kupisa simba, kadhi; Ini-ikozvino, ampere 9R-kupikisa, ohm, t-nguva, yechipiri.

Yakaverengerwa maererano neiyo fomula iri pamusoro, apo 1 kilowatt-awa yemagetsi simba inoshandurwa zvachose kuita kupisa simba, Q = (0.24 × 1000 × 36000) / 1000 = 864 kcal. Mumagetsi ekupisa tekinoroji, inoverengerwa se1 kilowatt awa = 860 kcal. Chivi chemagetsi chigadziro chinoshandura simba remagetsi kuita simba rinopisa mukugadzirisa, iro rinogona kushandiswa kupisa basa rakasarudzwa zvakanaka uye kuchengetedza kushanda kwepamusoro.

2. Iyo induction simbi yekudziya yevira isimba rekupa simba rinoshandura simba frequency 50HZ inochinjisa ikozvino kuita yepakati frequency (pamusoro pe100HZ kusvika 10000HZ) kuburikidza nepakati frequency magetsi ekupa, inoshandura matatu-chikamu simba frequency alternating ikozvino kuita yakananga ikozvino mushure mekugadzirisa. , uyezve inoshandura yakananga ikozvino inogadziriswa Iyo yepakati frequency ikozvino inopa yepakati frequency alternating ikozvino inoyerera kuburikidza ne capacitor uye induction coil, inogadzira yakakwirira-density magineti mitsetse yesimba mu induction coil, uye inocheka simbi zvinhu zviri muinduction. coil, ichigadzira yakakura eddy ikozvino mune simbi zvinhu, nokudaro Iyo simbi pachayo inogadzira kupisa kuzadzisa chinangwa chekudziya.

2. Zvakanakira induction simbi kudziyisa choto:

1. Iyo induction simbi inopisa vira inogona kushanda nguva dzose kwemaawa makumi maviri nemana. Uchishandisa musimboti weelectromagnetic induction, hombe eddy iripo inokurumidza kupinzwa mukati mesimbi zvinhu mune inochinjika magineti, kuitira kuti simbi inopisa kusvika yanyungudika. Iyo simbi yesimbi inopisa munharaunda kana zvachose nekukurumidza.

2. Induction metal heat furnaces kashoma kuva nematambudziko. Kana pane dambudziko, 90% inokonzerwa nekusakwana kwekumanikidza kwemvura kana kuyerera kwemvura. Inokurudzirwa kushandisa yemukati inotenderera yemvura system, kureva, yakavharwa inotonhorera shongwe, kutonhodza iyo yepakati frequency yekupisa vira, iyo ine mari uye inodhura-inoshanda.

3. Kupisa rhythm ye induction metal heat furnace inogona kugadzirwa maererano nekubudirira. Iyo yekupisa yekumhanyisa inogadzirwa zvinoenderana nesimba rekudziya, kupisa tembiricha uye huremu hwekudziya workpiece. Iyo yekupisa yekumhanyisa inogona kusvika ku1 sekondi uye inogona kugadziriswa zvisina tsarukano.

4. Iyo induction simbi yekudziya yevira ine yakafara yekupisa siyana, inogona kuve nemhando dzakasiyana dzekudziya, uye inogona kupisa akasiyana-siyana ebasa (anobvisa induction coils inogona kutsiviwa zvichienderana nechimiro cheworkpiece), senge kupera kupisa, kupisa kwese. , simbi

5. Izvo zvakanyanya nyore kutsiva sensor ye induction metal heat furnace, kureva, musoro wechoto, uye kutsiva kwe sensor kunogona kupedzwa mukati memaminitsi mashoma.

6. Kushanda kwesimbi induction metal heat furnace iri nyore. Simba rinogona kusimudzwa nekudzikiswa chete nekutenderedza knob yemagetsi. Kushanda kwese kunogona kudzidzwa kutanga nekukurumidza mumaminetsi mashoma, uye kupisa kunogona kutangwa mushure mekunge mvura yavhurwa.

7. The induction metal heat furnace ndeyekupisa kwakananga, nekuti kupisa kwemukati kwesimbi kunopisa kwakasiyana, uye hapana kurasikirwa kwekupisa kwemwaranzi conduction heat, saka inoshandisa simba shoma, kurasikirwa nekupisa kushoma, kudhumhana kwakanyanya, uye kushoma. kushandiswa kwesimba pane zvimwe zvigadzirwa zvakafanana. 20 %

8. The induction metal heat furnace ine yakanaka yekupisa kuita, yakanaka yekupisa kufanana uye yakakwirira yakazara maitiro. Iyo yepakati frequency firiji yemagetsi inopisa zvakanyanya kufanana (iyo density yeiyo induction coil inogonawo kugadziriswa kuti iwane tembiricha inodiwa kune yega yega chikamu chebasa).

9. The induction metal heat furnace ine mabasa akasiyana-siyana ekudzivirira kuderedza kushandiswa kwekukundikana uye simba rinogadziriswa. Kugadziriswa kusingaite kweinobuda simba rekudzivirira: ine overvoltage, overcurrent, overheating, kushomeka kwemvura uye zvimwe zviratidzo zvealarm, uye otomatiki kudzora nekudzivirira.

10. The induction metal heat furnace yakachengeteka uye yakavimbika. Iyo ine maalarm zviratidzo senge overvoltage, overcurrent, overheating, uye kushomeka kwemvura, uye inodzorwa nekuchengetedzwa otomatiki. Hapana kumanikidzwa kwakanyanya, kwakachengeteka kuti vashandi vashande.
