Thaum cov neeg feem coob hnov 'poob siv quav ciab qhov chaw', lawv pom cov flawless, ci iab turbine hniav los yog intricate art pieces. Qhov ntawd yog kev lag luam gloss. Qhov kev muaj tiag nyob rau hauv pem teb foundry yog ib tug grittier zaj dab neeg ntawm ceramic slurry viscosity, thermal expansion mismatches, thiab kev sib ntaus sib tua tsis tu ncua. Qhov loj tshaj misconception? Tias nws yog ib qho loj-haum-tag nrho cov txheej txheem precision. Tsis yog. Qhov kev kam rau siab koj tuaj yeem tuav ntawm lub tshuab me me stainless hlau phais yog lub ntiaj teb deb ntawm qhov ua tau zoo nrog cov nickel-based alloy twj tso kua mis loj, txawm tias siv tib lub hauv paus. ploj wax casting txoj cai. Dab ntxwg nyoog yog tag nrho hauv cov ntsiab lus uas lawv tsis tau muab tso rau hauv daim ntawv qhia.
Core Illusion: As-Cast Finish
Cov neeg siv khoom feem ntau thov kom ua tiav tiav, xav tias nws txuag nqi. Lawv feem ntau txhais tau li cas yog lawv xav tsis muaj machining. Tab sis nyob rau hauv kev xyaum, ib tug tiag tiag li-cam khwb cia nto los ntawm lub peev casting txheej txheem tseem xav tau qee qhov kev tu-txiav cov rooj vag, sib tsoo cov pob zeb. Qhov tseem ceeb tshaj plaws, qhov zoo ntawm qhov chaw yog nyob ntawm lub tsho loj ntawm lub plhaub ceramic. Ntawm peb lub khw, peb tau siv ntau xyoo hu rau hauv zircon hmoov / silica binder piv thiab ziab ib puag ncig. nrawm dhau, koj tau txais micro-cracks; ntub heev, lub plhaub nyob tsis muaj zog. Kuv nco qab txog ib pawg ntawm lub cev lub cev uas lub plhaub zoo li zoo meej, tab sis tom qab dewaxing thiab tua, ib qho kev sib txuas ntawm cov kab plaub hau tau tshwm sim. Tus neeg ua txhaum? Ib qho kev hloov maj mam thaum hmo ntuj poob thaum lub sij hawm tseem ceeb thawj lub tsho tiv no kom qhuav. Cov khoom tsis tau muab pov tseg, tab sis lawv yuav tsum tau kho weld dav, tsis muaj txiaj ntsig zoo.
Qhov no txuas ncaj qha rau hauv kev xaiv cov khoom siv. Cov neeg qhia 316 stainless rau txhua yam corrosive. Tab sis rau ploj wax casting qhov chaw uas dhau los ntawm thermal cycling, zoo li cov khoom siv tso tawm, tus qauv 316 tuaj yeem ua rau cov theem ntawm sigma nag lossis daus ntawm cov ciam teb, ua rau embrittlement. Peb feem ntau qhia cov neeg siv khoom xav txog qib hloov kho nrog thermal stability zoo dua. Nws yog ib qho kev sib tham nuanced uas txav dhau ntawm cov txheej txheem casting rau hauv metallurgy.
Qhov ntawd yog qhov uas tus foundry qhov kev suav suav. Ib lub tuam txhab xws li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nrog rau lawv peb lub xyoo caum hauv casting thiab machining, tau zoo li pom cov kev ua tsis tiav no. Lawv tsom mus rau cov ntaub ntawv xws li cobalt thiab npib tsib xee-raws li alloys qhia tias lawv cuam tshuam nrog kev siv zog siab uas cov txheej txheem nuances yog ua-lossis-so. Koj tsis tuaj yeem dag zoo li ntawd, qee zaum mob, kev paub.
Precision yog Kev Taug Kev, Tsis Muaj Kev Pov Hwm
Lub sij hawm precision peev casting yog bandied txog xoob. Qhov tseeb precision yog cov saw ntawm cov kauj ruam, txhua qhov qhia txog qhov yuam kev. Kev txhaj tshuaj siv quav ciab yog thawj qhov txuas tseem ceeb. Peb kawm qhov no txoj kev nyuaj nrog ib tug complex manifold. Tus qauv CAD yog zoo meej. Aluminium tooling yog qhov tseeb. Tab sis thaum lub sij hawm siv quav ciab, peb tsis suav txog qhov sib txawv shrinkage hla ntu tuab thiab nyias, ua rau warpage uas tsuas yog tshwm sim tom qab lub plhaub ceramic tau tsim. Qhov tshwm sim? Cam khwb cia qhov chaw uas tau dimensionally tawm ntawm spec, tsis yog los ntawm cov hlau pouring, tab sis los ntawm thawj heev wax qauv. Nws yog ib qho kev txo hwj chim uas yuam kom peb tsim cov nyiaj shrinkage rau hauv cov cuab yeej tsim raws li qhov tshwj xeeb siv quav ciab peb siv, ib yam dab tsi koj tsuas yog kawm los ntawm kev rov ua dua, tsis muaj nqi.
