Casting yog txheej txheem ntawm kev txhaj tshuaj molten hlau mus rau hauv lub hollow pwm ua los ntawm cov ntaub ntawv kub-resistant thiab condensing nws kom tau raws li qhov xav tau ntawm cov khoom.
Lub ntiajteb txawj nqus casting yog muab faib raws li txoj kev pouring, uas yog, cov kua hlau yog tsim los ntawm lub siab ntawm atmospheric siab.
Xuab zeb casting yog cais raws li cov khoom ntawm cov pwm kab noj hniav, uas yog tsim los ntawm cov xuab zeb thiab nchuav rau hauv cov kua hlau los tsim cov casting.
Lub ntiajteb txawj nqus casting yog hais txog cov txheej txheem ntawm kev txhaj tshuaj molten hlau rau hauv pwm nyob rau hauv lub zog ntawm lub ntiaj teb lub ntiajteb txawj nqus. Generalized gravity casting muaj xws li xuab zeb casting, hlau casting, peev casting, poob ua npuas ncauj casting, thiab lwm yam; nqaim txhais lub ntiajteb txawj nqus casting tshwj xeeb yog hais txog hlau pwm casting.
Xuab zeb casting yog txheej txheem qub qub thiab feem ntau cov txheej txheem hauv kev tsim khoom, uas siv cov xuab zeb ua cov khoom tseem ceeb molding ces pouring hauv cov xuab zeb moulding kom tau raw castings. Nws muaj ntau yam kev hloov pauv, suav nrog qhov me me thiab loj, qhov yooj yim thiab nyuaj, ib feem, thiab cov khoom loj. Cov pwm siv rau xuab zeb casting feem ntau yog ua los ntawm ntoo thiab hlau. Tsis tas li ntawd, cov xuab zeb pwm muaj hluav taws kub ntau dua li cov pwm hlau, yog li cov ntaub ntawv uas muaj cov ntsiab lus melting ntau dua xws li tooj liab alloys thiab cov hlau dub kuj siv cov txheej txheem no ntau zaus.
Txawm li cas los xij, kuj tseem muaj qee qhov tsis txaus ntawm cov xuab zeb casting: txhua cov xuab zeb pwm tuaj yeem tsuas yog nchuav rau ib zaug xwb, tom qab ntawd raug puas tsuaj tom qab pouring thiab tau txais cov casting, ces yuav tsum reshape tshiab rau ntau pouring, yog li cov efficiency ntawm cov xuab zeb casting yog kuj tsawg. . Qhov zoo tshaj plaws yog nrog kev txhim kho siab ntawm cov thev naus laus zis, tes molding tau hloov los ntawm Tsis Siv Neeg - molding los ntawm cov tshuab kab, cov khoom siv tau zoo dua niaj hnub no hauv Suav teb.
Vim lub zuag qhia tag nrho mos thiab ntxeem tau ntawm cov xuab zeb, qhov seem ntawm cov xuab zeb castings yog qis dua thiab qhov saum npoo kuj rougher. Txawm li cas los xij, nrog rau xyoo ntawm kev tsim cov thev naus laus zis, cov chaw tsim khoom lag luam precision tau zoo heev txhim kho qhov chaw ntawm cov xuab zeb castings, thiab lawv cov nyhuv tua blasting tuaj yeem piv rau cov hlau castings.
Hlau pwm casting yog txheej txheem niaj hnub uas siv cov hlau tsis muaj cua sov los ua cov hollow casting pwm rau casting. Hlau pwm tuaj yeem yog lub ntiajteb txawj nqus cam khwb cia lossis siab cam khwb cia. Cov pwm hlau tuaj yeem rov qab siv tau ntau zaus, thiab nrog txhua qhov nchuav ntawm cov hlau molten, ib qho casting tau txais, ua rau lub neej ntev thiab kev ua haujlwm siab. Hlau pwm castings tsis tsuas yog muaj qhov zoo ntawm qhov raug thiab du nto, tab sis kuj muaj zog dua thiab tsis tshua muaj kev puas tsuaj piv rau cov xuab zeb pwm castings thaum pouring tib cov kua hlau. Yog li ntawd, thaum tsim cov khoom nruab nrab thiab me me ntawm cov hlau tsis muaj hlau nyob rau hauv ntau qhov ntau, tsuav yog qhov melting point ntawm cov khoom siv casting tsis siab dhau, hlau pwm casting feem ntau nyiam dua.
Txawm li cas los xij, hlau pwm casting kuj tseem muaj qee qhov tsis txaus: vim tias cov hlau tsis muaj cua sov thiab kev ua cov kab noj hniav ntawm nws yog tus nqi kim, tus nqi ntawm cov pwm hlau pwm tsis kim, tab sis tag nrho, piv rau cov nqi ntawm cov pwm tuag. , nws yog pheej yig dua. Rau kev tsim khoom me me, tus nqi pwm faib rau txhua yam khoom yog qhov siab heev thiab feem ntau tsis yooj yim rau kev txais. Vim muaj kev txwv ntawm cov khoom pwm loj, cov khoom siv ua cov kab noj hniav, thiab cov khoom siv casting, cov pwm hlau kuj tseem tsis muaj zog rau cov khoom loj tshwj xeeb. Yog li ntawd, hlau pwm casting yog tsis tshua muaj siv nyob rau hauv me me thiab loj-scale ntau lawm. Tsis tas li ntawd, txawm hais tias hlau pwm pwm siv cov hlau tsis muaj cua sov, lawv cov cua sov kuj tseem txwv, thiab lawv feem ntau yog siv rau casting aluminium alloys, zinc alloys, thiab magnesium alloys. Lawv tsis tshua siv nyob rau hauv tooj liab alloy casting, thiab tsawg dua siv nyob rau hauv dub hlau casting.
