Cov tshuab tuag casting tsim ntau yam zoo li cov khoom siv los ntawm kev txhaj tshuaj molten hlau rau hauv pwm. Txawm li cas los xij, txawm hais tias nws txoj haujlwm ua haujlwm yog qhov yooj yim, txhawm rau ua kom cov khoom zoo thiab kev nyab xeeb ntawm kev ua haujlwm, ntau yam teeb meem yuav tsum tau muab sau tseg thaum ua haujlwm. Hauv qab no yog cov lus piav qhia ntxaws txog cov teeb meem tseem ceeb hauv kev ua haujlwm ntawm decompression casting tshuab.
1. Hlau pouring
Hlau pouring yog ib qho ntawm cov kauj ruam tseem ceeb hauv kev ua haujlwm ntawm cov khoom siv. Thaum lub sij hawm pouring, nws yog ib qhov tsim nyog los xyuas kom meej cov hlau ntws thiab tsis txhob sib tov ntawm gases los yog impurities. Lub pouring ceev thiab siab yuav tsum tau kho raws li qhov yuav tsum tau ntawm cov khoom thiab cov khoom kom ua tiav cov nyhuv filling.
2. Qhov pores thiab shrinkage porosity
Qhov pores thiab shrinkage porosity yog qhov kev tuag-casting tsis xws luag uas yuav txo tau lub zog thiab sealing ntawm cov khoom. Yuav kom txo tau qhov tshwm sim ntawm cov teeb meem no, nws yog ib qho tsim nyog yuav tsum tau ua kom tsim nyog cov dej ntws thiab kev ntsuas cua txias, thiab xyuas kom meej tias cov pwm tsim tuaj yeem tshem tawm cov pa roj kom zoo.
3. Pwm Tsim
Cov pwm yog ib qho tseem ceeb ntawm cov txheej txheem tuag-casting, uas cuam tshuam ncaj qha rau qhov zoo thiab qhov tseeb ntawm cov khoom. Yog li ntawd, ua ntej siv lub tshuab tuag-casting, nws yog ib qho tsim nyog yuav tsum ua tib zoo tsim thiab tsim cov pwm kom paub meej tias nws tuaj yeem ua raws li cov khoom xav tau. Kev tsim cov pwm kuj yuav tsum tau xav txog txoj hauj lwm ntawm qhov tso pa tawm, qhov cua txias, thiab lub rooj vag kom tsis txhob muaj qhov tsis xws luag xws li porosity thiab shrinkage.
4. Kev cob qhia tus neeg ua haujlwm
Cov cuab yeej ua haujlwm yuav tsum muaj kev txawj ntse thiab kev paub dhau los. Cov neeg ua haujlwm yuav tsum tau txais kev cob qhia kom nkag siab txog kev ua haujlwm ntawm lub tshuab, cov txheej txheem kev nyab xeeb, thiab cov txheej txheem teb thaum muaj xwm txheej ceev. Kev cob qhia yuav tsum muaj kev paub txog kev hloov pwm, kev tso khoom, thiab kev saib xyuas cov cuab yeej kom muaj kev nyab xeeb thiab ua haujlwm tau zoo thaum ua haujlwm.
5. Kev tswj qhov kub thiab txias
Kub yog ib qho tseem ceeb parameter nyob rau hauv cov txheej txheem tuag casting, uas ncaj qha cuam tshuam rau qhov zoo ntawm cov khoom. Nws yog ib qho tsim nyog los xyuas kom meej tias cov hlau melting kub, pwm kub, thiab txias npaum li cas yog nruj me ntsis tswj. Kev kub siab lossis qis qis tuaj yeem ua rau muaj qhov tsis xws luag lossis tsis sib xws hauv lub koom haum ntawm cov khoom.
6. Kev ntsuas kev nyab xeeb
Lub tshuab tuag-casting ua rau muaj qhov kub thiab txias siab thaum lub sijhawm ua haujlwm, yog li kev ntsuas kev nyab xeeb yog qhov tseem ceeb. Cov neeg ua haujlwm yuav tsum hnav cov khoom tiv thaiv tsim nyog, suav nrog cov khaub ncaws tiv thaiv kub kub, qhov ncauj qhov ntswg, hnab looj tes, thiab pob ntseg. Tsis tas li ntawd, nws yog ib qho tsim nyog yuav tsum tau xyuas thiab tswj cov cuab yeej ua haujlwm kom ntseeg tau tias kev ua haujlwm ib txwm muaj ntawm ntau yam khoom siv kev nyab xeeb, xws li kev nyab xeeb li qub, lub siab sensors, thiab cov khawm nres thaum muaj xwm ceev.
7. Kev tswj kom zoo
Kev tswj kom zoo yog ib feem tseem ceeb ntawm cov txheej txheem tuag-casting. Ib qho kev tswj xyuas nruj nruj yuav tsum tau tsim, nrog rau kev tshuaj xyuas thiab kev soj ntsuam ntawm cov khoom loj, qhov pom, thiab kev ua haujlwm. Yog tias pom muaj teeb meem, kev kho yuav tsum tau ua raws sijhawm kom ntseeg tau tias cov khoom tsis raug cai tsis nkag mus rau hauv kev ua lag luam.
Cov teeb meem uas yuav tsum tau them sai sai rau thaum lub sijhawm ua haujlwm ntawm lub tshuab tuag-casting muaj ntau yam. Tsuas yog los ntawm kev tswj xyuas kev tshawb fawb thiab kev ua haujlwm nruj tuaj yeem ua kom zoo thiab kev nyab xeeb ntawm cov khoom siv tuag-casting.
