Kev nqis peev casting, tseem hu ua poob ciab casting, tau tsim 5,000 xyoo dhau los.Txoj kev casting no muab qhov tseeb, rov ua dua thiab ntau yam nrog cov hlau sib txawv thiab kev ua haujlwm siab alloys.Txoj kev casting no tsim nyog rau qhov tsis hnov tsw thiab precision qhov chaw thiab yog kim tshaj li lwm txoj kev casting.Nrog kev tsim khoom loj, tus nqi tsev yuav poob qis.
Kev nqis peev casting txheej txheem:
Ciab Qauv Ua: Kev nqis peev casting tuam ntxhab yuav tsum ua cov qauv siv quav ciab rau lawv cov khoom siv quav ciab.Feem ntau cov peev txheej casting yuav tsum tau ua cov txheej txheem casting siab heev kom ua tiav cov kauj ruam no.
Wax ntoo los ua ke: Tus nqi ntawm kev tsim ib qho peev txheej casting khoom yog siab, thiab nrog cov ntoo siv quav ciab, peev casting tuam ntxhab tuaj yeem tsim cov txiaj ntsig ntau dua.
Plhaub ua: Ua cov hnab plhaub ntawm cov ntoo siv quav ciab, ua kom lawv ruaj khov thiab siv cov txheej txheem casting tom ntej.
Kev tshem tawm cov quav ciab: Tshem tawm cov quav ciab sab hauv yuav muab cov kab noj hniav uas koj tuaj yeem nchuav hlau molten rau hauv qhov ua tiav.
Plhaub khob: Tom qab cov hlau molten solidifies, khob tawm lub plhaub kom tau cov hlau casting khoom ntoo.Txiav lawv los ntawm tsob ntoo thiab koj yuav muaj qhov kawg peev cam khwb cia khoom.
Technical nta:
1. High dimensional precision thiab geometric raug;
2. High deg roughness;
3. Nws tuaj yeem nrum castings nrog cov duab complex, thiab cov alloys yuav tsum tau cam khwb cia yog tsis txwv.
Disadvantages: txheej txheem nyuaj thiab tus nqi siab
Daim ntawv thov: haum rau kev tsim cov khoom me me nrog cov duab nyuaj, siab precision, lossis nyuaj rau kev ua lwm yam, xws li turbine cav hniav, thiab lwm yam.
1. Nws tuaj yeem nrum complex castings ntawm ntau yam alloys, tshwj xeeb tshaj yog superalloy castings.Piv txwv li, lub streamlined txheej profile thiab cua txias sab hauv kab noj hniav ntawm cov hniav ntawm lub dav hlau cav tsis tuaj yeem tsim los ntawm cov txheej txheem machining.Kev tsim cov peev txheej casting I thev naus laus zis tuaj yeem ua tsis tau tsuas yog ua tiav ntau lawm, xyuas kom meej qhov sib xws ntawm cov casting, tab sis kuj zam qhov kev ntxhov siab ntawm cov hniav seem tom qab machining.
2. Qhov tseeb qhov tseeb ntawm peev castings yog qhov siab, feem ntau mus txog CT4-6 (CT10 ~ 13 rau xuab zeb casting thiab CT5 ~ 7 rau tuag casting).Tau kawg, vim qhov nyuaj ntawm kev nqis peev casting txheej txheem, muaj ntau yam cuam tshuam rau qhov tseeb qhov tseeb ntawm castings, xws li shrinkage ntawm cov khoom pwm, deformation ntawm peev pwm, kev hloov pauv ntawm lub plhaub pwm thaum lub sij hawm lub sij hawm. cua sov thiab cua txias txheej txheem, shrinkage ntawm kub thiab deformation ntawm lub casting thaum lub sij hawm solidification txheej txheem, qhov tseeb qhov tseeb ntawm cov peev txheej castings yog qhov siab, Txawm li cas los xij, nws qhov sib xws tseem yuav tsum tau txhim kho (qhov sib xws ntawm castings nrog nruab nrab thiab siab. kub ciab yuav tsum tau txhim kho ntau heev)
3. Thaum nias lub peev pwm, cov pwm uas muaj qhov siab kawg ntawm cov pwm kab noj hniav yog siv.Yog li ntawd, qhov nto tiav ntawm cov peev pwm kuj tseem muaj siab.Tsis tas li ntawd, lub plhaub pwm yog ua los ntawm hluav taws-resistant txheej ua los ntawm tshwj xeeb high-temperature resistant nplaum thiab refractory cov ntaub ntawv, uas yog coated nyob rau hauv lub peev pwm.Qhov saum npoo tiav ntawm cov pwm kab noj hniav ncaj qha nyob rau hauv kev sib cuag nrog cov hlau molten yog siab.Yog li ntawd, qhov saum npoo ntawm cov peev txheej casting yog siab dua li ntawm qhov zoo tib yam castings, feem ntau mus txog Ra.1.3.2 μ m.
4. Qhov zoo tshaj plaws ntawm kev nqis peev casting yog vim tias peev casting muaj qhov tseeb qhov tseeb thiab qhov chaw tiav, nws tuaj yeem txo qhov kev ua haujlwm ntawm machining.Tsuas yog ib qho me me ntawm machining pub tuaj yeem tso rau qhov chaw uas yuav tsum tau muaj siab, thiab txawm tias qee qhov castings tuaj yeem siv yam tsis muaj kev siv tshuab.Nws tuaj yeem pom tias txoj kev peev casting tuaj yeem txuag tau ntau lub tshuab cov cuab yeej thiab lub sijhawm ua haujlwm, thiab txuag cov khoom siv hlau zoo heev.
