Centrifugal casting - txoj kev muab tseeb teb

Centrifugal casting - ib txoj kev rau kev tsim teb castings, uas yog raws li nyob rau hauv cov teebmeem ntawm centrifugal quab yuam nyob rau hauv molten loj ntawm cov khoom. Foundry, yog koom nyob rau hauv qhov siv thiab ua zoo li tus teb thiab ntxhib castings, muaj ib tug ntau yam ntawm txoj kev casting: ntsawj txias, nyob rau hauv cov xuab zeb-av nplaum tuaj pwm, tshwj xeeb ciab casting, nyob rau hauv siab, thiab lwm yam Tab sis qhov zoo tshaj tau pom casting yog centrifugal casting.

Nyob rau hauv essence, txoj kev muaj nyob rau hauv uas los ntawm centrifugal quab yuam cov molten khoom uniformly kis tshaj lub puab nto pwm thiab crystallizing ntaub ntawv ib tug dawb paug nrog yuav tsum tau tsis. Tsis txhob xav hais tias txoj kev no yog tsuas muaj feem xyuam rau cov hlau thiab lawv cov alloys. Nyob rau hauv qhov tseeb, casting yas khoom tau ua unusually ntau. Tab sis yas muaj ib tug xov tooj ntawm cov nta uas yuav tsum tau raug xam tias yog thaum ua hauj lwm nrog lawv. Yas Txhaj yog feem ntau nqa tawm nyob rau hauv siab, uas muab tshwj xeeb cov khoom precision.

Nyob rau hauv Feem ntau, ntau hom casting yog siv los tsim hlau castings. Yog li, centrifugal casting muaj ob peb zoo :. Tsis hollow voids thiab slag inclusions nyob rau hauv lub resulting cam khwb cia, high-ceev cov ntaub ntawv, muaj zog hlau coj kuj, uas yog tiav los ntawm cov niaj hnub qauv, thiab lwm yam Lub ntsiab zoo ntawm cov qauv no yog hu ua cov ntaub ntawv uas cov nyiaj khaws tseg rau hauv lub workpiece thiab ib tug tseem ceeb yuav txo tau nyob rau hauv complexity ntawm tag nrho cov txheej txheem txheej txheem (vim lub maximal approximation casting rau hauv lub tiav lawm khoom).

Centrifugal casting muaj ib tug xov tooj ntawm "rho tawm". Cov muaj xws li: tau tsis muaj tseeb free chaw ntawm lub workpiece, cov ntsuam mus rau theem sib cais cov ntaub ntawv uas cov ntaub ntawv uas nqi (vim lub zog uas yuav tsum tau ntawm seem raug).

Tshwj xeeb cov cav tov yog siv nyob rau hauv lub centrifugal casting txoj kev. Lawv txawv nyob rau hauv cov kev taw qhia ntawm lub axis ntawm kev sib hloov - ntsug, kab rov tav thiab inclined axis (qhov tseeb, yav tag los yog tsis tshua muaj siv). Machine nrog ntsug axis siv los tsim me me-ntev billets nrog me sib txawv ntawm cov kauj ruam (ib ncig, pistons, tes tsho thiab cov zoo li). Machine nrog ib tug kab rov tav axis ntawm kev sib hloov tso cai rau kom tau ntev-ntev high-precision castings nrog ib tug phab ntsa thickness ntawm ib tug. Ib yam li ntawd npaj los ntawm cov qauv ntawm cov cam khwb cia-hlau kav. Qhov no yog cov feem ntau ntau. Siv centrifugal casting yuav ua tau kav nrog phab ntsa ntawm 80 mus rau 300 hli (nyob ntawm seb cov khoom siv). Qhov tshaj plaws xwb uas koj yuav tsum tau twv yuav raug hu kom nyob rau hauv lub siab yog qhov tseeb hais tias nrog rau cov qauv, nrog kev nyuab siab tshwm sim nyob rau hauv lub teb. Yog li ntawd, tom qab muab castings tsim nyog rau kev annealing.

centrifugal casting txoj kev thiab yog npaj rau lwm yam preform qhov chaw, uas tshwm sim tawm lub cev ntawm kiv puag ncig. Tshwj xeeb tshaj yog nrov precision casting txoj kev yog siv nyob rau hauv qhuav ntawm billets los ntawm uas tsis yog-ferrous co (qhov no txoj kev tso cai rau koj mus cawm kim ntaub ntawv).
