Lub valve casting yog pov rau hauv lub valve, qhov siab ntawm lub valve casting feem ntau yog qis dua (xws li PN16, PN25, PN40, tab sis kuj muaj qhov siab siab, tuaj yeem yog 1500Lb, 2500Lb), feem ntau yog caliber ntau dua DN50. Lub valve forged yog forged tawm, feem ntau siv rau hauv cov kav dej qib siab, qhov caliber yog me dua, feem ntau qis dua DN50.

1, casting: yog yaj cov hlau rau hauv cov kua uas ua tau raws li qee yam yuav tsum tau ua thiab pov rau hauv pwm, tom qab txias thiab khov, ntxuav kom tau txais cov duab, qhov loj me thiab kev ua tau zoo ntawm cov txheej txheem casting (qhov chaw lossis dawb paug). Cov thev naus laus zis yooj yim ntawm kev lag luam tsim khoom siv niaj hnub.

2, casting tsim khoom pheej yig, rau cov duab nyuaj, tshwj xeeb tshaj yog nrog cov qhov sib txawv ntawm cov kab sib txawv, ntau dua tuaj yeem qhia nws txoj kev lag luam; tib lub sijhawm, nws muaj kev hloov pauv dav dua thiab cov khoom siv kho tshuab zoo dua.

3, tab sis casting ntau lawm xav tau cov ntaub ntawv (xws li hlau, ntoo, roj, molding cov ntaub ntawv, thiab lwm yam) thiab cov khoom siv (xws li metallurgical cub tawg, xuab zeb sib tov tshuab, molding tshuab, core ua tshuab, xuab zeb poob tshuab, txhaj tshuaj blasting tshuab, cam khwb cia hlau phaj, thiab lwm yam) ntau dua, thiab yuav tsim cov hmoov av, cov pa phem thiab suab nrov thiab kev ua qias tuaj ntawm ib puag ncig.

4, casting yog ib qho txheej txheem ua hlau kub uas tib neeg nkag siab thaum ntxov, thiab qhov ceev ntawm casting yog ceev heev, thiab tau tsim cov hlau cam khwb cia nodular, hlau cam khwb cia malleable, hlau stainless hlau uas tsis muaj carbon ntau thiab tooj liab txhuas, txhuas silicon, txhuas magnesium alloy, titanium, nickel alloy thiab lwm yam khoom siv hlau cam khwb cia, thiab tau tsim cov txheej txheem tshiab rau kev kho cov hlau cam khwb grey. Tom qab xyoo 1950, muaj cov xuab zeb ntub dej siab siab, cov xuab zeb ua kom tawv thiab cov tub ntxhais ua, cov qauv siab tsis zoo thiab lwm yam casting tshwj xeeb, kev tua blasting thiab lwm yam thev naus laus zis tshiab.

5, muaj ntau hom casting, raws li txoj kev ua qauv, feem ntau muab faib ua: (1) xuab zeb casting, suav nrog xuab zeb ntub, xuab zeb qhuav thiab hom xuab zeb hardening 3. ② Kev casting tshwj xeeb, Cov ntaub ntawv molding nias thiab tuaj yeem muab faib ua xuab zeb ntuj tsim ua cov ntaub ntawv molding tshwj xeeb tseem ceeb (piv txwv li, kev nqis peev casting, pwm casting, plhaub pwm casting foundry, negative pressure casting, pwm casting, ceramic pwm casting, thiab lwm yam) thiab hlau ua cov ntaub ntawv pwm tseem ceeb ntawm kev casting tshwj xeeb (xws li hlau pwm casting, siab casting, tas mus li casting, qis siab casting, centrifugal casting, thiab lwm yam).

6, cov txheej txheem casting feem ntau muaj xws li: (1) casting (thawv) ua kua hlau khov kho casting, casting raws li cov ntaub ntawv tuaj yeem muab faib ua xuab zeb pwm, hlau, ceramic, av nkos, graphite, thiab lwm yam, tuaj yeem faib ua pov tseg, semi-permanent thiab tas mus li hom, qhov zoo ntawm kev npaj pwm yog cov yam tseem ceeb uas cuam tshuam rau qhov zoo ntawm casting; (2) kev yaj thiab casting ntawm casting hlau, casting hlau (casting alloy) feem ntau yog cam khwb cia hlau, cam khwb cia hlau thiab cam khwb cia tsis yog hlau alloy; casting kev kho thiab kev tshuaj xyuas casting, casting kev kho mob suav nrog kev tshem tawm cov tub ntxhais thiab casting nto txawv teb chaws, tshem tawm cov dej ntws, shovel sib tsoo burr thiab seam thiab lwm yam protrusions thiab kev kho cua sov, yas, xeb kho thiab ua cov khoom ntxhib.
