Casting tu yog txheej txheem tseem ceeb hauv kev tsim cov khoom siv hlau, tshwj xeeb hauv kev lag luam xws li tsheb, aerospace, thiab cov tshuab hnyav. Tom qab cov hlau tau raug nrum lawm, cov khoom tsim, hu ua casting, feem ntau yuav tsum tau ua ntxiv kom tshem tawm cov khoom siv ntau dhau, qhov tsis zoo ntawm qhov chaw, thiab lwm yam tsis xav tau. Cov txheej txheem no ua kom ntseeg tau tias cov khoom kawg ua tau raws li qhov xav tau tshwj xeeb thiab cov qauv zoo.
Cov txheej txheem ntawm Casting Cleaning
1. Mechanical Cleaning:
Txhaj tshuaj Blasting: Qhov no yog txoj kev siv ntau tshaj plaws, qhov twg cov khoom abrasive (tshuaj tua) yog propelled ntawm kev kub ceev kom tshem tawm cov nplais, xuab zeb, thiab lwm yam khoom seem ntawm qhov casting. Nws zoo heev rau kev ntxuav ferrous thiab non-ferrous hlau. Kev txhaj tshuaj blasting feem ntau yog siv rau hauvpeev castinglos ntxuav cov duab puab ntawm cov castings, tshwj xeeb tshaj yog cov uas muaj cov txheej txheem sab hauv uas nyuaj rau kev ntxuav los ntawm lwm txoj kev.
Sib tsoo: Kev sib tsoo yog siv lub log sib tsoo los yog siv txoj siv tawv kom tshem tawm cov khoom siv ntau dhau, xws li flash lossis fins, thiab kom du tawm qhov tsis sib xws. Txoj kev no feem ntau yog siv rau kev ua haujlwm kom ntxaws ntxiv.
Vibratory Finishing: Hauv cov txheej txheem no, castings tau muab tso rau hauv lub tshuab vibratory uas muaj cov xov xwm abrasive. Qhov kev vibration ua rau cov xov xwm rub tawm ntawm cov castings, polishing lawv thiab tshem tawm cov khoom xoob los yog burrs. Txoj kev no yog qhov zoo rau qhov me thiab nruab nrab.
2. Tshuaj ntxuav:
Pickling: Pickling yuav immersing lub casting nyob rau hauv ib tug acid tov kom tshem tawm cov nto oxides thiab impurities. Txoj kev no yog qhov tshwj xeeb tshaj yog rau cov hlau tsis muaj hlau thiab lwm yam hlau tsis muaj hlau. Txawm li cas los xij, nws yuav tsum tau ua tib zoo tuav vim qhov corrosive yam ntawm cov tshuaj koom nrog.
Electropolishing: Qhov no yog cov txheej txheem electrochemical uas smooths thiab ntxuav qhov chaw ntawm casting los ntawm kev tshem tawm ib txheej nyias ntawm cov hlau. Nws feem ntau yog siv rau cov khoom uas yuav tsum tau ua kom huv si thiab cov iav zoo li ua tiav, xws li cov khoom siv hauv kev kho mob lossis zaub mov qib.
3. Thermal Cleaning:
Hlawv tawm: Nyob rau hauv txoj kev no, castings raug rau kub kub nyob rau hauv lub cub tawg kom hlawv tawm tej residual xuab zeb, cores, los yog binders. Qhov no yog tshwj xeeb tshaj yog zoo rau castings nrog intricate intricate passages, qhov twg mechanical tu tej zaum yuav nyuaj.
Kev siv thiab tsim nyog
AutomotiveKev lag luam: Kev txhaj tshuaj blasting thiab sib tsoo feem ntau yog siv los ntxuav lub cav thaiv, lub tog raj kheej taub hau, thiab lwm yam khoom loj.
Aerospace Kev Lag Luam: Cov tshuaj ntxuav cov txheej txheem xws li electropolishing yog qhov nyiam rau cov khoom siv uas xav tau qib siab ntawm qhov tseeb thiab qhov chaw tiav, xws li turbine hniav thiab lwm yam tseem ceeb.
Hnyav Machinery: Vibratory finishing thiab txhaj tshuaj blasting yog feem ntau ua hauj lwm los ntxuav thiab deburr loj castings siv nyob rau hauv cov khoom hnyav thiab machinery.
Xaus
Xaiv txoj kev tu kom tsim nyog yog nyob ntawm cov khoom siv ntawm qhov casting, qhov nyuaj ntawm qhov, thiab qhov xav tau nto tiav. Kev tu kom zoo yog qhov tseem ceeb rau kev ua kom ntseeg tau tias cov casting ua tau raws li qhov yuav tsum tau ua thiab kev zoo nkauj, ua rau nws yog ib qho tseem ceeb hauv kev tsim khoom tag nrho.
