Kev siv nyiaj tuaj pwm yog ib pawg dav ntawm cov txheej txheem uas cov pwm siv los ua qhov hlau yog rhuav tshem "tom qab txhua lub voj voog casting. Qhov no yog nyob rau hauv sib piv rau cov pwm ua tau tas mus li, qhov twg cov pwm tuaj yeem siv ntau dua. Lub hauv paus ntsiab lus ntawm kev siv tau pwm me me yog los tsim cov pwm kab noj hniav uas phim cov hlau uas xav tau, thiab cia cov hlau kom muaj zog. Thaum cov hlau muaj kev ruaj khov, cov pwm raug tawg kom tshem tawm cov nrum.
Muaj ntau hom kev siv tau los ntawm kev siv pwm pov thawj:
Xuab zeb casting:
Qhov no yog ib qho ntawm feem ntau siv tau siv tau siv tau siv tau siv tau siv tau siv ntau yam siv tau. Hauv cov xuab zeb casting, cov pwm yog tsim los ntawm cov xuab zeb sib xyaw nrog cov binders. Ib tus qauv, uas yog ib qho qauv ntawm ib feem kom tau nrum, yog siv los tsim cov kab noj hniav hauv cov xuab zeb pwm. Lub molten hlau yog ces ncuav rau hauv kab noj hniav, thiab tom qab solidification, cov xuab zeb pwm tau tawg los rho tawm cov nrum. Xuab zeb casting yog haum rau ntau qhov ntau thiab tsawg thiab raug nqi - ua tau zoo rau tsawg - rau - nruab nrab ntau lawm. Nws tuaj yeem siv nrog ntau cov hlau, suav nrog txhuas, hlau, thiab hlau. Piv txwv, cov cav ntau cov cav rau cov tsheb thiab hnyav - cov dej num machinery feem ntau tsim kev siv xuab zeb casting.
Peev Casting:
Kuj tau paub tias ploj - ciab casting, peev Casting koom nrog kev tsim cov qauv siv quav ciab ntawm qhov xav tau ua ntej. Cov qauv ciab no yog tom qab ntawd coated nrog lub plhaub ceramic, thiab cov ciab me me tawm, tawm hauv cov kab noj hniav hauv cov ceramic plhaub. Molten hlau tau nchuav rau hauv cov kab noj hniav no, thiab tom qab solidification, cov ceramic plhaub tau tawg tseg. Peev Casting yog qhov tseeb heev thiab tuaj yeem tsim cov chaw nrog cov lus qhia nyuaj thiab cov ntsiab lus zoo. Nws yog ib qho siv nyob rau hauv kev lag luam xws li aerospace, qhov twg cov khoom siv zoo li cov tshuab kho mob yuav tsum tau ua kom ruaj khov, thiab hauv cov khoom kho mob kom tsim tau cov khoom siv kho mob thiab hauv kev kho mob. Piv rau lwm qhov kev siv nyiaj tuaj yeem siv cov qauv me me, kev nqis peev casting tuaj yeem ua tiav qhov chaw siab dua thiab yog feem ntau kim thiab muaj cov sijhawm ua rau cov ntu nyuaj.
Plhaub Moulding:
Zoo ib yam li cov xuab zeb casting, plhaub moulding siv cov xuab zeb - cob haum sib xyaw. Txawm li cas los xij, hloov kev tsim cov khoom siv xuab zeb pwm, ib lub plhaub nyias ntawm cov xuab zeb - cob tov sib xyaw yog tsim nyob ib ncig ntawm cov qauv rhuab. Daim plhaub no ces yog sib sau ua ke los ua cov pwm kab noj hniav. Plhaub molding muab cov khoom sib npaug zoo dua thiab feem ntau siv rau kev tsim cov khoom me me - rau cov khoom siv me me, xws li lub cav sib xyaw thiab lub cev valve.
Plaster moulation plaster casting: Hauv cov txheej txheem no, pwm yog tsim los ntawm plaster - raws cov khoom. Cov plaster sib xyaw yog hliv ib ncig ntawm tus qauv los tsim cov pwm kab noj hniav. Pliv pwm Casting yog tsim rau tsis yog - ferrous hlau thiab tuaj yeem tsim cov chaw nrog cov chaw zoo ua tiav. Nws feem ntau yog siv rau kev tsim cov khoom zoo nkauj, cov hniav nyiaj hniav kub, thiab cov khoom siv me me.
Kev siv dua tuaj pwm Casting muaj ntau qhov zoo.
Firstly, nws muab qib siab ntawm kev tsim qauv loj, tso cai rau kev tsim cov khoom nrog cov duab sib xyaw thiab cov yam ntxwv sab hauv.
Qhov thib ob, vim tias cov pwm raug puas tsuaj tom qab siv, tsis tas yuav txhawj xeeb txog kev hnav pwm thiab kua muag, uas tuaj yeem cuam tshuam rau cov khoom lag luam zoo hauv cov khoom lag luam.
Ib qho ntxiv, kev siv pwm me me ua cov txheej txheem tuaj yeem siv nrog ntau cov hlau, los ntawm cov hlau thiab hlau kom ntau cov alloys tshwj xeeb. Txawm li cas los xij, ib qho ntawm lub ntsiab drawbacks yog tias cov pwm xav tau tsim rau txhua lub voj voog casting, uas tuaj yeem ua rau lub sijhawm thiab tus nqi ntau dua.
Hauv cov ntsiab lus, kev siv tau los ntawm cov txheej txheem sib xyaw ua ke yog cov txheej txheem tseem ceeb hauv kev tsim khoom hauv niaj hnub no
