Thaum siv quav ciab los ua tus qauv, peev casting kuj hu ua "poob ciab casting".Kev nqis peev casting feem ntau yog hais txog cov txheej txheem casting uas cov duab yog tsim los ntawm cov khoom siv fusible, qhov saum npoo ntawm cov duab yog coated nrog ob peb txheej ntawm cov ntaub ntawv refractory los ua lub plhaub pwm, thiab tom qab ntawd cov pwm yog yaj tawm ntawm lub plhaub pwm, yog li. raws li tau txais cov pwm tsis muaj qhov sib cais, uas tuaj yeem ntim nrog xuab zeb thiab nchuav tom qab kub kub roasting.Kev nqis peev casting feem ntau hu ua "poob ciab casting" vim yog siv ntau cov ntaub ntawv waxy los tsim cov qauv.

Cov hom hlau uas tsim los ntawm peev casting yog carbon steel, alloy steel, tshav kub-resistant alloy, stainless hlau, precision alloy, ruaj hlau nplaum alloy, bearing alloy, tooj liab alloy, aluminium alloy, titanium alloy thiab nodular cam khwb cia hlau, thiab lwm yam.

Feem ntau, cov duab ntawm peev castings yog qhov nyuaj.Qhov tsawg kawg nkaus txoj kab uas hla ntawm lub qhov casting tuaj yeem ncav cuag 0.5 hli, thiab qhov tsawg kawg nkaus phab ntsa thickness yog 0.3 hli.Hauv kev tsim khoom, qee qhov chaw tsim los ntawm ntau qhov chaw tuaj yeem tsim rau hauv ib feem thiab ncaj qha nrum los ntawm peev casting los ntawm kev hloov cov qauv ntawm cov khoom, thiaj li yuav txuag tau cov sijhawm ua haujlwm thiab cov khoom siv hlau, yog li cov qauv ntawm cov khoom siv. tsim nyog dua.

Feem ntau ntawm qhov hnyav ntawm kev nqis peev castings yog li ntawm xoom mus rau kaum ob ntawm cov newtons (los ntawm ob peb grams mus rau kaum kilograms, feem ntau tsis ntau tshaj 25 kilograms).Nws yog teeb meem siv peev casting los tsim hnyav castings.

Cov txheej txheem ntawm kev nqis peev casting yog qhov nyuaj, thiab nws tsis yooj yim los tswj, thiab cov khoom siv thiab cov khoom siv yog kim dua.Yog li ntawd, nws yog tsim nyog rau zus tau tej cov me me qhov chaw nrog complex duab, high precision yuav tsum, los yog lwm yam kev nyuaj, xws li turbine cav hniav.
