Taw qhia rau castings

Castings yog hlau zoo li cov khoom tau los ntawm ntau txoj kev casting. Ntawd yog, smelted kua hlau yog poured rau hauv ib tug pre-npaj pwm los ntawm pouring, txhaj tshuaj, inhalation los yog lwm yam casting txoj kev. Tom qab txias, nws yog polished thiab lwm cov txheej txheem tom ntej. , lub resulting khoom nrog ib tug tej yam duab, loj thiab kev ua tau zoo.
Casting Keeb Kwm
Casting applications muaj keeb kwm ntev. Nyob rau hauv ancient sij hawm, tib neeg siv castings los ua thiab qee yam khoom siv niaj hnub. Niaj hnub no, castings feem ntau yog siv los ua blanks rau tshuab qhov chaw. Qee qhov precision castings kuj tuaj yeem siv ncaj qha los ua tshuab qhov chaw. Castings account rau ib feem loj ntawm cov khoom siv tshuab. Piv txwv li, hauv cov tsheb laij teb, qhov hnyav ntawm castings suav txog li 50 mus rau 70% ntawm qhov hnyav ntawm tag nrho lub tshuab, hauv cov tshuab ua liaj ua teb nws suav txog 40 txog 70%, thiab hauv cov cuab yeej siv tshuab thiab cov tshuab hluav taws xob sab hauv, nws suav txog 70 mus rau 90%. Ntawm ntau hom castings, castings rau machinery muaj ntau yam loj tshaj plaws, feem ntau cov duab, thiab kev siv loj tshaj plaws, suav txog kwv yees li 60% ntawm tag nrho cov khoom tsim tawm. Tom ntej no yog steel ingot pwm rau metallurgy, kav dej rau engineering, thiab qee yam cuab yeej hauv lub neej txhua hnub.
Castings kuj tseem cuam tshuam nrog lub neej txhua hnub. Piv txwv li, feem ntau siv lub qhov rooj tuav, qhov rooj xauv, lub tshuab hluav taws xob, cov kav dej, cov lauj kaub hlau, cov qhov cub roj, cov hlau, thiab lwm yam yog txhua yam castings.
