Nrog rau qhov nce ntawm kev thov thiab kev xav tau rau kev tuag castings, cov hlau lead alloy tuag casting tshuab yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua ntawm kev ua haujlwm ntev. Txawm hais tias cov neeg ua haujlwm txawj lossis cov novices, lawv yuav pom tias thaum cov cuab yeej ua haujlwm tsis tu ncua, qee zaum lub taub hau rauj tau daig, uas ua rau qeeb ntawm kev ua tiav. Yuav ua li cas kom tsis txhob lub taub hau rauj tau daig?Koj tuaj yeem pib los ntawm ob yam hauv qab no:
1. Nyob rau ntawm qhov chaw uas cov khoom tuag-casting ua tau raws li qhov yuav tsum tau ua, qhov ntsuas kub ntawm cov cuab yeej yuav tsum tau kuaj xyuas tsis tu ncua, tshwj xeeb tshaj yog qhov kub ntawm lub taub hau rauj thiab lub thoob tsav tsheb. Thaum qhov ntsuas kub ntawm lub taub hau rauj thiab tus tsav tsheb tau pom tias siab dhau lawm, qee qhov kev ntsuas yuav tsum tau coj los txo qhov kub. Vim hais tias ib zaug qhov kub ntawm lub taub hau rauj thiab tus tsav lub tog raj kheej tshaj qhov ua tau zoo, lub taub hau rauj yog yooj yim mus daig.
2. Ntawm qhov chaw ua tau raws li qhov yuav tsum tau ua, nws yog ib qho tsim nyog yuav tau xaiv cov khoom zoo zoo casting alloy, thiab sim tsis txhob infiltrate residues rau hauv cov ntaub ntawv raw. Thaum ib sab yog tuag-casting, lub taub hau rauj yuav daig vim cov khoom tsis zoo. Nyob rau tib lub sijhawm, nyob rau hauv cov txheej txheem ntawm kev tuag casting, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo saib kom tsis txhob cia cov seem nkag mus rau hauv txoj haujlwm ua haujlwm, thiab cov seem yuav ua raws li lub taub hau rauj, uas yuav ua rau lub taub hau rauj yuav daig.
Txhawm rau kom ntseeg tau tias kev ua haujlwm ib txwm muaj thiab ruaj khov ntawm cov cuab yeej, ob lub ntsiab lus hauv qab no yuav tsum tau sau tseg thaum ua haujlwm:
1. Thaum tuag-casting kub pwm, kua aluminium alloy tuaj yeem siv los tuag-cam khwb cia 5-10 cov pwm kub ntawm tus nqi qis, thiab tom qab ntawd ib txwm muaj cov khoom siv txhuas txhuas thiab cov khoom siv semi-tiav tuaj yeem siv rau tuag-casting. Qhov kom zoo dua ntawm qhov no yog tias nws tuaj yeem tiv thaiv pwm, txuas ntxiv lub neej kev pab cuam ntawm pwm, thiab tiv thaiv cov khoom ya thaum lub sij hawm tag nrho cov txheej txheem ntawm tuag casting.
2. Yuav kom tsis txhob muaj kev sib nrig sib cuam tshuam ntawm cov ntaub ntawv teeb liab RF connector thiab relay thaum lub sij hawm tuag casting, uas yuav ua rau cov ntaub ntawv teeb liab yuam kev thiab ua rau muaj kev huam yuaj, yuav tsum tau xyuam xim rau seb cov ntaub ntawv teeb liab RF connector thiab relay yog li qub thaum tuag. casting.
Thaum cov cuab yeej ua haujlwm, txhawm rau ua kom muaj kev nyab xeeb, lub ntsiab hloov pauv ntawm lub zog hluav taws xob yuav tsum raug muab tua thiab lub zog hloov hluav taws xob yuav tsum raug txiav.
