1. Casting txhais

Casting qhov chaw, tseem hu ua casting, yog siv txhua yam ntawm casting txoj kev rau hlau tsim cov khoom, uas yog cov zoo kua hlau smelting, casting, txhaj tshuaj, nqus tau los yog lwm yam casting txoj kev rau hauv lub npaj pwm, tom qab txias tom qab sib tsoo thiab lwm yam ua raws li. up processing txhais tau tias, ntawm ib tug tej yam zoo li, qhov loj thiab cov khoom ntawm cov khoom.

2. Casting Keeb Kwm

Casting applications muaj keeb kwm ntev.Cov neeg Ancient siv cov castings thiab qee yam khoom siv rau kev ua neej nyob.

Nyob rau lub sijhawm niaj hnub no, castings feem ntau yog siv los ua qhov khoob rau lub tshuab qhov chaw, thiab qee qhov precision castings kuj tuaj yeem siv ncaj qha los ua tshuab qhov chaw.

Casting occupies ib tug loj feem ntau nyob rau hauv txhua yam khoom, xws li tsheb laij teb, casting hnyav account rau txog 50 ~ 70% ntawm lub luj ntawm tag nrho cov tshuab, ua liaj ua teb machinery account rau 40 ~ 70%, tshuab cuab yeej, internal combustion engine, thiab lwm yam. mus txog 70 ~ 90%.

Ntawm tag nrho cov hom ntawm castings, mechanical castings muaj ntau yam loj tshaj plaws, feem ntau complex duab thiab ntau npaum li cas, accounting txog li 60% ntawm tag nrho cov khoom ntawm castings.Qhov no yog ua raws li metallurgical ingot pwm thiab engineering kav, nrog rau qee yam cuab yeej hauv lub neej.

Castings kuj tseem cuam tshuam nrog lub neej txhua hnub.Piv txwv li, feem ntau siv cov qhov rooj, qhov rooj xauv, lub tshuab hluav taws xob, cov kav dej ntws thiab cov dej ntws, cov POTS hlau, cov qhov cub hluav taws xob, cov hlau, thiab lwm yam.

3. Casting Classification

Castings muaj ntau hom kev faib tawm:

Raws li cov khoom siv hlau sib txawv siv, nws tau muab faib ua steel casting, cam khwb cia hlau, cam khwb cia tooj liab, cam khwb cia txhuas, cam khwb cia magnesium, cam khwb cia zinc, cam khwb cia titanium thiab lwm yam.

Txhua hom casting tuaj yeem muab faib ua ntau hom raws li nws cov tshuaj muaj pes tsawg leeg lossis cov qauv metallographic.Piv txwv li, cam khwb cia hlau yuav muab faib ua grey cam khwb cia hlau, nodular cam khwb cia hlau, vermicular cam khwb cia hlau, malleable cam khwb cia hlau, alloy cam khwb cia hlau, thiab lwm yam.

Raws li cov txheej txheem molding sib txawv, castings tuaj yeem muab faib ua cov xuab zeb zoo tib yam, hlau castings, tuag castings, centrifugal castings, nruam castings, peev castings, ceramic castings, electroslag remelting castings, bimetallic castings, thiab lwm yam.

Ntawm lawv, cov xuab zeb zoo tib yam yog siv ntau tshaj plaws, suav txog li 80% ntawm tag nrho cov castings.Thiab txhuas, magnesium, zinc thiab lwm yam tsis-ferrous hlau castings, feem ntau tuag castings
