Thawj kauj ruam yog mus nias lub wax pwm
Nias cov khoom siv quav ciab rau hauv cov pwm kab noj hniav, muab nws tawm tom qab tau condensed los ntawm lub tshuab dej khov dej, muab tso rau hauv lub tank dej rau lub sijhawm, thiab tau txais ib qho quav pwm tom qab ua tiav thiab tshuaj xyuas. Wax pwm tuaj yeem nkag siab tias yog qhov siab casting qhov chaw.
Kauj Ruam 2: kev tsim pwm
Cov pwm yog siv los nias cov qauv casting. Txhawm rau kom ntseeg tau qhov zoo ntawm cov pwm pwm, cov pwm yuav tsum muaj qhov tseeb qhov tseeb thiab qhov me me ntawm qhov roughness tus nqi.
Kauj Ruam 3: kho pwm
Qhov zoo, nto zoo thiab deformation degree ntawm wax pwm txiav txim siab qee qhov tseem ceeb ntawm cov khoom. Yog li ntawd, wax pwm Rhiav xav tau kev tswj qhov kub thiab txias kom txo tau qhov deformation ntawm wax pwm. Nyob rau tib lub sijhawm, qhov saum npoo ntawm txhua qhov quav pwm kuj yuav tsum tau kuaj xyuas. Cov uas muaj cov cim ntws yuav tsum tau muab ntxuav tawm. Nyob rau tib lub sijhawm, burr, flash thiab clamping kab ntawm cov khoom siv quav ciab yuav tsum tau muab tshem tawm thaum kho pwm, thiab cov kab mob yuav tsum tau kho.
Kauj Ruam 4: Muab cov khoom siv quav ciab (Pob ntoo)
Tom qab kev kho pwm, rau qhov tsim nyog ib leeg wax pwm, txhawm rau txhim kho cov khoom tsim tau, ib qho pwm pwm yog fusion welded rau ntawm cov khoom siv ua ntej npaj siv quav ciab los tsim ib pawg wax pwm. Feem ntau, 2 ~ 80 wax pwm tuaj yeem welded ntawm ib pawg wax pwm.
Kauj Ruam 5: ntxuav cov wax pwm
Cov pab pawg wax pwm tom qab tsim tsob ntoo tuaj yeem ntxuav tom qab sawv ntsug rau ntau tshaj 45 feeb. Ua ntej lub plhaub ua thiab slurry dai, cov wax pwm pawg tom qab muaj pes tsawg pawg yuav tsum tau ntxuav kom tshem tawm cov wax chips thiab roj rau ntawm qhov chaw thiab txhim kho cov adhesion ntawm lub plhaub ua.
Kauj Ruam 6: tsim lub plhaub
Tom qab dipping thiab dai cov txheej sab nraud ntawm cov quav ciab pwm, muab tso rau hauv lub plhaub ua kom qhuav. Cov txheej txheej saum npoo tau siv txoj kev ziab kom qhuav, thiab cov txheej txheem hloov pauv thiab rov qab txheej tau txais cov txheej txheem ziab cua kom nrawm nrawm. Nyob rau hauv txoj kev no, txheej thiab dai yog rov ua dua rau 5 ~ 7 zaug (5 ~ 6 txheej rau me me castings thiab 6 ~ 9 txheej rau loj castings).
Kauj Ruam 7: plhaub roasting, ncuav, xuab zeb ntog thiab tu
Lub plhaub dewaxed yuav tsum tau roasted thaum pouring. Lub plhaub yuav tsum tau ci rau hauv 1100 ℃ roj hluav taws xob hluav taws xob hluav taws xob rau 50 feeb. Lub hom phiaj tseem ceeb yog tshem tawm cov wax residual tom qab dewaxing, txhim kho lub zog thiab huab cua permeability ntawm lub plhaub thiab tiv thaiv lub plhaub los ntawm deformation los yog rupture thaum lub sij hawm pouring.
Kauj Ruam 8: dewaxing thiab siv quav ciab kho
Ncuav lub plhaub pwm rau hauv qhov cub dewaxing ax kom yaj cov quav pwm thiab ntws tawm hauv qab. Cais nws los ntawm cov dej separator, sau cov kua siv quav ciab, thiab muab tso rau hauv lub thoob dej tshem tawm kom ntxiv cov dej ciab cais thiab tshem tawm cov impurities hauv cov quav ciab.
