Hauv kev ua cov hlau muaj nqis, cov tshuab kub thiab nyiaj induction melting sawv tawm nrog lawv cov kev ua tau zoo heev thiab cov txheej txheem ua haujlwm zoo, ua rau cov khoom siv nyiam rau ntau tus kws kho mob. Nws koom ua ke cov thev naus laus zis induction cua sov siab heev thiab lub kaw lus tswj qhov kub kom raug, muab cov kev daws teeb meem zoo thiab zoo rau kev yaj cov hlau muaj nqis xws li kub thiab nyiaj.
kub thiab nyiaj induction melting tshuab
1,Lub hauv paus ntsiab lus ntawm kev kub hnyiab induction tso lub hauv paus rau kev ua haujlwm siab
Lub tshuab yaj kub thiab nyiaj induction siv lub hauv paus ntsiab lus ntawm electromagnetic induction kom ua tiav cov hlau kub thiab nyiaj kub sai. Thaum lub zog hloov pauv hla lub kauj induction, lub zog hloov pauv magnetic raug tsim, thiab cov hluav taws xob eddy raug tsim sab hauv cov khoom siv kub thiab nyiaj hauv lub zog sib nqus vim yog electromagnetic induction. Cov hluav taws xob eddy no ua rau cov hlau kub nws tus kheej sov sai, yog li ua tiav lub hom phiaj ntawm kev yaj. Txoj kev cua sov no muaj qhov zoo dua piv rau cov txheej txheem cua sov ib txwm muaj xws li hluav taws kub. Nws tuaj yeem nce qhov kub ntawm cov hlau mus rau nws qhov chaw yaj sai sai hauv lub sijhawm luv luv, ua rau lub voj voog yaj luv luv thiab txhim kho kev ua haujlwm ntau lawm. Piv txwv li, thaum ua tiav qee yam khoom siv kub, lub tshuab yaj induction tuaj yeem yaj nws hauv ob peb feeb xwb, thaum hluav taws kub yuav siv sijhawm ntev dua ob peb zaug, thiab lub zog tuaj yeem ua haujlwm rau cov hlau nws tus kheej thaum lub sijhawm cua sov, txo qhov poob zog tsis tsim nyog thiab ua tiav cov txiaj ntsig txuag hluav taws xob tseem ceeb.
2,Kev tswj qhov kub thiab txias kom raug ua kom zoo ib yam
Kev ua cov hlau muaj nqis yuav tsum tau tswj qhov kub thiab txias kom raug heev, thiab txawm tias qhov kub me me kuj tuaj yeem cuam tshuam rau qhov huv ntawm cov hlau thiab qhov zoo ntawm cov khoom kawg. Lub tshuab yaj kub thiab nyiaj induction muaj lub kaw lus tswj qhov kub siab heev, uas saib xyuas qhov kub hauv lub cub tawg hauv lub sijhawm tiag tiag los ntawm cov sensors kub siab thiab muab cov lus teb rau lub kaw lus tswj, yog li ua tiav qhov kev hloov kho qhov kub kom raug. Thaum yaj kub thiab nyiaj alloys, qhov kub tuaj yeem tswj tau ruaj khov hauv qhov sib txawv me me, xyuas kom meej tias muaj kev faib tawm ntawm cov khoom sib xyaw, zam kev sib cais hlau los ntawm kev kub dhau lossis txias dhau, thiab xyuas kom meej tias txhua pawg ntawm cov khoom hlau muaj nqis ua tiav muaj qhov ruaj khov thiab zoo heev. Txawm hais tias nws yog qhov nyuaj, xim, lossis kev ntshiab, lawv tuaj yeem ua tau raws li cov qauv kev lag luam nruj thiab cov neeg siv khoom xav tau.
3,Yooj yim rau kev khiav lag luam thiab muaj kev nyab xeeb thiab txhim khu kev qha tib lub sijhawm
(1) Cov kauj ruam ua haujlwm
Theem npaj: Ua ntej siv lub tshuab yaj kub thiab nyiaj induction, yuav tsum tau kuaj xyuas cov khoom siv kom zoo kom paub tseeb tias lub kauj induction, lub kaw lus txias, lub voj voog hluav taws xob thiab lwm yam khoom siv zoo li qub thiab tsis muaj qhov tsis zoo. Ua ntej kho cov khoom siv kub thiab nyiaj uas yuav tsum tau yaj, tshem tawm cov khoom tsis huv, txiav lawv rau hauv qhov loj me, thiab ntsuas thiab sau cia kom raug. Tib lub sijhawm, npaj lub crucible tsim nyog thiab muab tso rau hauv lub cub tawg ntawm lub cub tawg yaj, xyuas kom meej tias lub crucible tau teeb tsa ruaj ntseg.
Fais fab rau thiab qhov chaw teeb tsa parameter: Txuas lub hwj chim, tig rau lub kaw lus tswj hwm ntawm lub tshuab yaj, thiab teeb tsa lub zog cua sov, lub sijhawm yaj, qhov kub thiab lwm yam kev ntsuas ntawm qhov interface ua haujlwm raws li hom thiab qhov hnyav ntawm cov hlau yaj. Piv txwv li, thaum yaj 99.9% kub ntshiab, qhov kub tau teeb tsa ntawm ib puag ncig 1064℃thiab lub zog raug kho kom haum raws li qhov ntau ntawm cov kub kom ntseeg tau tias cov txheej txheem yaj du.
Cov txheej txheem yaj: Tom qab pib qhov kev pab cuam cua sov, tus neeg teb xov tooj yuav tsum saib xyuas qhov xwm txheej hauv lub cub tawg yaj thiab cov kev ua haujlwm ntawm cov khoom siv. Thaum qhov kub nce ntxiv, cov khoom siv kub thiab nyiaj maj mam yaj. Lub sijhawm no, lub xeev yaj ntawm cov hlau tuaj yeem pom los ntawm cov qhov rai saib xyuas lossis cov khoom siv saib xyuas kom ntseeg tau tias cov hlau yaj tag nrho mus rau hauv lub xeev kua sib xws. Thaum lub sijhawm smelting, lub kaw lus txias ntawm cov khoom siv yuav ua haujlwm sib xws kom ntseeg tau tias cov khoom tseem ceeb xws li cov kauj induction tuaj yeem ua haujlwm ib txwm nyob rau hauv qhov chaw kub siab thiab tiv thaiv kev puas tsuaj overheating.
Kev txhaj tshuaj molding:Tom qab cov hlau yaj tag thiab mus txog qhov kub thiab txias uas xav tau, siv cov cuab yeej tshaj lij los nchuav cov hlau ua kua rau hauv pwm uas tau npaj tseg rau kev pwm. Thaum lub sijhawm pwm, yuav tsum tau saib xyuas kev tswj qhov ceev thiab lub kaum sab xis kom ntseeg tau tias cov hlau ua kua puv lub pwm kom sib npaug, zam kev puas tsuaj xws li porosity thiab shrinkage, thiab yog li tau txais cov khoom hlau zoo.
Kaw thiab ntxuav:Tom qab ua tiav txoj haujlwm yaj thiab casting, ua ntej tua qhov kev pab cuam cua sov thiab cia lub cub tawg yaj txias ntuj rau ib lub sijhawm. Tom qab qhov kub poob qis mus rau qhov chaw nyab xeeb, tua lub zog, lub kaw lus txias, thiab lwm yam khoom siv ntxiv. Ntxuav cov khoom tsis huv thiab cov khoom seem hauv lub cub tawg kom npaj rau kev ua haujlwm smelting tom ntej.
(2) Kev ua tau zoo ntawm kev ruaj ntseg
Tus qauv tsim ntawm lub tshuab yaj kub thiab nyiaj induction xav txog tag nrho cov yam ntxwv kev nyab xeeb ua haujlwm. Nws muaj ntau txoj hauv kev tiv thaiv kev nyab xeeb, xws li kev tiv thaiv overcurrent, kev tiv thaiv overvoltage, kev tiv thaiv overheating, thiab lwm yam. Thaum cov khoom siv ntsib teeb meem tam sim no, voltage, lossis kub siab, nws yuav txiav lub zog hluav taws xob kom tiv thaiv cov khoom siv puas tsuaj thiab kev nyab xeeb. Tib lub sijhawm, lub plhaub ntawm cov khoom siv yog ua los ntawm cov khoom siv rwb thaiv tshav kub thiab tiv taus hluav taws, txo qhov kev pheej hmoo ntawm kev kub hnyiab ntawm tus neeg teb xov tooj. Thaum lub sijhawm ua haujlwm, tus neeg teb xov tooj tswj hwm qee qhov kev ncua deb nyab xeeb ntawm thaj chaw yaj kub siab, thiab kev ua haujlwm deb yog ua tiav los ntawm lub kaw lus tswj hwm tsis siv neeg, ntxiv kev nyab xeeb ntawm tus kheej thiab ua rau tag nrho cov txheej txheem ua haujlwm zoo, muaj kev nyab xeeb, thiab txhim khu kev qha.
