Lub luag hauj lwm ntawm txhua yam ntawm cov induction melting rauv

Ib qho, cov ntsiab lus tseem ceeb

Cov khoom siv yooj yim hais txog cov khoom siv uas yuav tsum muaj cov khoom siv rau kev ua haujlwm ib txwm muaj.

1-1, transformer XNUMX

Lub transformer yog ib qho khoom siv uas muab cov khoom siv hluav taws xob xav tau rau cov khoom siv.

Transformers tuaj yeem muab faib ua cov tshuab ziab khaub ncaws qhuav thiab roj-txias transformers raws li kev sib txawv txias txias.

Hauv kev lag luam nruab nrab zaus rauv, peb pom zoo kom cov roj txias txias rectifier transformers.

Hom transformer no zoo dua li cov transformers zoo tib yam nyob rau hauv cov nqe lus ntawm overload muaj peev xwm thiab tiv thaiv kev cuam tshuam.

Cov yam ntxwv cuam tshuam rau lub peev xwm ntawm transformer

1) Hlau core

Cov khoom ntawm cov tub ntxhais hlau ncaj qha cuam tshuam rau cov sib nqus flux,

Cov ntaub ntawv tseem ceeb ntawm cov hlau muaj xws li cov ntaub ntawv silicon steel (oriented / non-oriented) thiab amorphous strips;

2) Hlau pob khoom

Tam sim no muaj cov pob khoom txhuas hlau xaim, tooj liab tub ntxhais hlau pob, thiab tooj liab clad txhuas hlau pob.

Cov khoom siv ntawm cov xaim pob ncaj qha cuam tshuam rau kev tsim hluav taws xob ntawm lub transformer;

3) Rwb thaiv tsev chav kawm

Qhov tso cai ua haujlwm kub ntawm chav kawm B yog 130 ℃, thiab qhov tso cai ua haujlwm kub ntawm chav kawm H yog 180 ℃

1-2, nruab nrab zaus fais fab mov

Qhov nruab nrab zaus fais fab mov txee yog qhov tseem ceeb ntawm lub system.

Tsis muaj teeb meem dab tsi ntawm qhov nruab nrab zaus fais fab mov yog, nws yog tsim los ntawm ob qhov chaw: rectifier / inverter.

Lub luag haujlwm ntawm lub rectifier ib feem yog hloov pauv 50HZ alternating tam sim no siv hauv peb lub neej rau hauv lub zog ncaj qha tam sim no. Raws li tus naj npawb ntawm cov pulse rectified, nws tuaj yeem muab faib ua 6-pulse rectification, 12-pulse rectification, 24-pulse rectification thiab lwm yam.

Tom qab rectification, ib tug smoothing reactor yuav txuas nrog nyob rau hauv series ntawm tus ncej zoo.

Lub luag haujlwm ntawm inverter ib feem yog hloov cov tam sim no ncaj qha tsim los ntawm kev hloov kho rau hauv qhov nruab nrab zaus hloov tam sim no.

1-3, capacitor txee

Lub luag haujlwm ntawm lub txee capacitor yog muab cov khoom siv hluav taws xob reactive rau lub induction kauj.

Nws tuaj yeem nkag siab yooj yim tias tus nqi ntawm capacitance ncaj qha cuam tshuam rau lub zog ntawm lub cuab yeej.

yuav tsum paub tias yog,

Muaj tsuas yog ib hom resonant capacitor (hluav taws xob cua sov capacitor) rau cov khoom siv sib txuas.

Ntxiv rau qhov resonant capacitor (hluav taws xob cua sov capacitor), cov cuab yeej siv kuj tseem muaj lub lim dej capacitor.

Qhov no kuj tseem siv tau los ua ib qho kev ntsuas rau kev txiav txim seb lub cuab yeej yog ib qho khoom sib txuas lossis cov cuab yeej siv.

1-4, cub lub cev

1) Rauv lub cev kev faib tawm

Lub tshuab hluav taws xob lub cev yog qhov ua haujlwm ntawm qhov system. Raws li cov khoom ntawm lub cub tawg, nws muab faib ua ob hom: steel plhaub thiab txhuas plhaub.

Cov qauv ntawm aluminium plhaub rauv yog qhov yooj yim, muaj tsuas yog induction kauj thiab lub qhov cub lub cev. Vim tias cov qauv tsis ruaj khov, nws raug txwv tsis pub siv tam sim no. Yog li peb cov lus piav qhia tsom mus rau lub plhaub steel qhov cub.

2) Lub hauv paus ntsiab lus ua haujlwm ntawm lub tshuab ua kom sov

Cov haujlwm tseem ceeb ntawm lub tshuab ua kom sov yog tsim los ntawm peb ntu,

1 Induction coil (ua los ntawm cov yeeb nkab dej txias)

2 Crucible (feem ntau yog ua los ntawm cov khoom siv hauv ob sab phlu)

3 Kev Them Nyiaj (ntau yam hlau lossis cov khoom tsis yog hlau)

Lub hauv paus ntsiab lus ntawm induction rauv yog ib hom cua core transformer.

Lub induction kauj yog sib npaug rau thawj kauj ntawm lub transformer,

Cov khoom siv hluav taws xob ntau yam nyob rau hauv lub crucible yog sib npaug rau theem nrab ntawm lub transformer,

Thaum qhov nruab nrab zaus tam sim no (200-8000HZ) dhau los ntawm lub hauv paus kauj, nws yuav tsim cov kab sib nqus ntawm lub zog los txiav cov coil thib ob (burden) nyob rau hauv qhov kev txiav txim ntawm electromagnetic teb, uas ua rau lub nra ntawm lub induced electromotive quab yuam, thiab induce ib tug induced tam sim no nyob rau saum npoo perpendicular mus rau lub axis ntawm induction kauj. Yog li ntawd tus nqi nws tus kheej heats thiab melts tus nqi.
