A: Kev kub siab casting yog ib txoj hauv kev uas cov kua roj molten yog nchuav rau hauv lub siab chamber, ib kab noj hniav ntawm cov pwm hlau tau ntim rau ntawm qhov kub ceev, thiab cov kua alloy yog solidified nyob rau hauv siab los tsim ib tug casting.Cov yam ntxwv tseem ceeb ntawm kev tuag casting uas paub qhov txawv ntawm lwm txoj kev casting yog kev kub siab thiab kev kub ceev.

Tuag casting tshuab, tuag-casting alloys thiab tuag-casting pwm yog peb lub ntsiab tseem ceeb ntawm kev tuag-casting ntau lawm thiab yog indispensable.Cov txheej txheem hu ua tuag-casting yog cov organic ua ke ntawm peb lub ntsiab lus, ua kom ruaj khov, sib dhos thiab ua haujlwm zoo ntawm castings nrog cov tsos, zoo sab hauv, thiab qhov loj ntawm cov duab kos lossis cov kev cai ntawm kev pom zoo.

A:

(1) Nws tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev tuag castings.

(2) Lub melting point yog tsawg, lub crystallization kub ntau yog me me, lub fluidity ntawm qhov kub siab tshaj lub melting point yog zoo, thiab tus nqi ntawm shrinkage tom qab solidification yog me me.

(3) Nws muaj lub zog txaus thiab plasticity ntawm qhov kub thiab txias, thiab tsis muaj kub brittleness.

(4) Cov khoom zoo ntawm lub cev thiab tshuaj lom neeg xws li hnav tsis kam, hluav taws xob conductivity, thermal conductivity, thiab corrosion kuj.

A: Feem ntau, daim ntawv thov tiag tiag hauv kev lag luam tuag-casting tsis yog 100% ntshiab txhuas, tab sis nrog cov ntsiab lus txhuas ntawm 95% mus rau 98.5% (tuag-cam khwb cia txhuas alloy nrog zoo anodizing kev ua tau zoo), thiab ntshiab txhuas yuav tsum muaj. ntau tshaj 99.5% txhuas (xws li ntshiab txhuas rotor tuag casting).Vim nws cov thermal conductivity zoo thiab cov khoom siv anodizing, alumina feem ntau yog siv rau hauv cov dab dej kub thiab kev kho deg uas cov xim yuav tsum muaj siab.

Piv nrog rau cov pa txhuas alloy tuag-casting (xws li ADC12), vim muaj cov ntsiab lus ntawm silicon siab, tus nqi shrinkage yog me me 4-5%;Tab sis lub alumina yog yeej tsis muaj silicon, tus nqi shrinkage yog 5-6%, yog li cov pa aluminium alloy tuag-casting tsis muaj anodizing nyhuv.

A: Lub tshuab tuag-casting tuaj yeem muab faib ua ob hom, kub chamber tuag casting tshuab thiab txias chamber tuag casting tshuab.Qhov txawv yog nyob rau hauv ntau npaum li cas quab yuam lawv tuaj yeem tiv taus.Qhov siab tshaj plaws yog los ntawm 400 mus rau 4,000 tons.Kub chamber tuag casting yog molten, kua, semi-kua hlau nyob rau hauv ib tug hlau pas dej ua ke uas sau cov pwm nyob rau hauv siab.Txias tuag casting tuaj yeem siv rau cov hlau tuag casting uas tsis tuaj yeem siv rau hauv cov txheej txheem kub kub tuag casting, suav nrog txhuas, magnesium, tooj liab, thiab zinc alloys nrog cov ntsiab lus txhuas ntau dua.Nyob rau hauv cov txheej txheem no, cov hlau yuav tsum tau melted ua ntej nyob rau hauv ib tug cais crucible.Ib qho nyiaj ntawm cov hlau molten yog tom qab ntawd xa mus rau qhov chaw txhaj tshuaj tsis muaj cua sov lossis lub nozzle;qhov sib txawv ntawm lub chamber kub thiab lub txias chamber yog seb qhov kev txhaj tshuaj ntawm lub tshuab tuag casting yog immersed nyob rau hauv cov hlau tov.

A: Kub chamber tuag casting tshuab: zinc alloy, magnesium alloy, thiab lwm yam.

Txias chamber tuag casting tshuab: zinc alloy, magnesium alloy, aluminium alloy, tooj liab alloy, thiab lwm yam.

Vertical tuag casting tshuab: zinc, txhuas, tooj liab, txhuas, tin;

A:

1. Kev ua haujlwm zoo casting

2. Tsawg ceev (2.5 ~ 2.9 g / cm3), siab zog.

3. Cov kua hlau uas muaj kev kub ntxhov thiab ceev ceev thaum lub sij hawm tuag casting

4, cov khoom zoo yog qhov zoo, qhov loj yog ruaj khov, thiab kev sib hloov pauv tau zoo;

5, kev ua haujlwm siab ntau lawm, cov sij hawm siv cov pwm tuag;

6, haum rau ntau cov khoom loj, kev lag luam zoo.

A: Feem ntau siv rau hauv kev kho qhov chaw ntawm aluminium alloy tuag-casting qhov chaw yog: electrophoretic xim, electroplating, roj txhaj, xuab zeb blasting, txhaj tshuaj blasting, anodizing, ci kua roj vanish, kub kub baking varnish, anti-xeb passivation thiab thiaj li nyob.
