kev puas tsuaj
Thaum lub sij hawm tuag-casting ntau lawm, lub pwm tsim muaj dua los ntawm kev cuam tshuam ntawm txias poob siab thiab kub, thiab molding saum npoo thiab nws sab hauv yog deformed, uas cuam tshuam rau ib leeg thiab rov ua hluav taws xob thermal ua kom muaj kev ntxhov siab, ua rau muaj kev puas tsuaj rau tus qauv thiab poob ntawm cov tawv. , ua rau muaj qhov tshwm sim ntawm micro-tawg thiab txuas ntxiv mus nthuav tawm Thaum cov nrib pleb nthuav tawm, molten hlau txhuam hauv, thiab rov ua cov cav tov kev ntxhov siab nrawm dua qhov tawg. Vim li no, ntawm ib sab tes, tus pwm yuav tsum tau ua kom tiav tag nrho thaum pib ntawm qhov tuag casting. Tsis tas li ntawd, cov pwm yuav tsum ceev nyob rau hauv qee yam kev ua haujlwm kub thaum lub sijhawm tuag casting kom tsis txhob tawg thaum ntxov. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog yuav tsum paub tseeb tias cov xwm txheej sab hauv ua ntej cov pwm raug muab tso rau hauv kev tsim khoom thiab thaum lub sijhawm tsim khoom tsis ua teeb meem. Hauv kev ua ntau lawm, feem ntau ntawm cov pwm tsis ua haujlwm yog thermal qaug zog ua tsis tiav.
Tawg
Raws li qhov kev txiav txim siab ntawm kev txhaj tshuaj siab, pwm yuav tawg ntawm qhov chaw tsis muaj zog, tshwj xeeb tshaj yog cov cim sau lossis cov tshuab hluav taws xob rau ntawm qhov chaw moulding tsis tau polished, lossis cov kab nrib pleev me me yuav tshwm sim ua ntej hauv cov ntshiab fab ntawm pwm Thaum muaj txheej txheem thawb lossis txhuam ntxhib hauv cov ciam nplej, nws yooj yim tawg. Txawm li cas los xij, qhov kev sib tsoo tawg tau sai heev thaum lub pob tawg, uas yog qhov phom sij rau qhov txhawm rau pwm. Vim li no, ntawm ib sab tes, txhua qhov khawb thiab hluav taws xob tshuab hluav taws xob rau ntawm cov pwm nto yuav tsum tau polished, txawm tias nws yuav nyob hauv qhov txheej txheem nchuav, nws kuj yuav tsum tau txhuam. Ntxiv rau, cov ntaub ntawv siv mould siv yuav tsum muaj lub zog zoo, yas zoo, zoo cuam tshuam ntawm tawv thiab tawv tawv.
Kev txiav txim siab
Raws li tau hais los saum toj no, feem ntau ntawm cov khoom siv tuag-casting alloys yog zinc alloys, alloys alloys, alloys magnesium thiab tooj liab alloys, ntxiv rau cov txhuas tuag-casting alloys. Zn, Al, Mg yog cov ntsiab lus muaj hlau ntau dua, thiab lawv muaj kev sib raug zoo nrog cov ntaub ntawv pwm. Tshwj xeeb Al yog yooj yim mus tom. Thaum lub hardness ntawm cov pwm siab, qhov ua hauj corrosion yog qhov zoo, thiab yog hais tias muaj qhov mos mos ntawm qhov chaw moulding, nws yog qhov ua rau xeb ua hauj corrosion.
Muaj ntau yam ua rau lub pwm ua tiav, thiab muaj lwm yam sab nraud (xws li qhov kub ntawm qhov casting, seb pwm puas raug preheated, tus nqi ntawm cov tshuaj tsuag txheej, seb lub tonnage loj ntawm lub tshuab tuag casting qhov sib tw, lub siab ntawm kev tuag casting yog siab dhau, qhov nrawm ntawm lub rooj vag nrawm dhau, lub tshuab dej txias qhib tsis yog synchronized nrog cov khoom tsim ntawm kev tuag-casting, hom casting khoom thiab cov muaj pes tsawg leeg ntawm Fe, qhov loj me thiab cov duab ntawm cov casting , phab ntsa tuab, hom xim pleev xim, thiab lwm yam). Nws kuj tseem muaj cov teeb meem sab hauv (xws li cov xim hlau zoo ntawm cov pwm nws tus kheej, cov txheej txheem forging ntawm seem, qhov meej pem ntawm cov qauv pwm tsim, qhov meej pem ntawm qhov tsim ntawm cov txheej txheem nchuav, cov kev ntxhov siab sab hauv tsim tawm thaum lub sij hawm ua cov pwm tshuab (kev siv hluav taws xob), cov txheej txheem kev kho cua sov ntawm pwm, nrog rau Ntau yam kev xav tau rau kev ua tiav thiab ua tiav, thiab lwm yam). Yog tias pwm tsis ua tiav thaum ntxov, nws yog qhov yuav tsum tau tshawb pom qhov twg hauv lossis sab nraud ua rau kev txhim kho yav tom ntej. Txawm li cas los xij, nyob rau hauv ntau lawm tiag tiag, qhov kev xaus mus tsuas yog nyob hauv ib cheeb tsam hauv lub pwm ntawd. Piv txwv li, ntu (qhov tseem ceeb, kab noj hniav) ncaj qha yaig ntawm lub rooj vag yog nquag pov tseg, thiab cov nplaum ntawm cov txhuas hlau yog qhov cuam tshuam tau tshwm sim hauv qhov muag muag khov.
