Koj hnov 'poob ciab casting stainless hlau' thiab ntau tus neeg pom qhov tsis zoo no, yuav luag cov txheej txheem zoo nkauj uas koj tau txais qhov zoo tshaj plaws stainless hlau ncaj qha tawm ntawm pwm. Qhov tseeb, tshwj xeeb tshaj yog cov qib xws li 304 lossis 316, yog ntau ntxiv txog kev tswj cov kev cia siab thiab paub qhov twg cov txheej txheem sib ntaus koj. Nws tsis yog tsuas yog melting hlau thiab pouring nws; Nws yog kev sib tham nrog cov khoom siv tus cwj pwm, los ntawm cov qauv siv quav ciab mus rau qhov kawg grind. Lub ci tuaj tom qab, tom qab kev daws teeb meem ntau heev.
Alloy tsis yog ib daim ntawv tshwj xeeb xwb
Xaiv cov qib stainless yog thawj qhov kev txiav txim siab tiag tiag, thiab nws tsis yog ib txwm ncaj qha. 316 yog qhov mus-rau kev tiv thaiv corrosion, paub meej, tab sis nws tus cwj pwm casting txawv ntawm 304. Nws yog qhov ua rau kub tearing yog tias koj lub rooj vag thiab cua txias tsis tau hu rau hauv. Qee lub sij hawm, koj yuav tsum thawb rov qab thiab tawm tswv yim rau kev hloov kho rau tus qauv tsim lossis sib tham yog tias CF8M (qhov sib npaug ntawm 316) nrog kev hloov kho me ntsis rau kev ua kom zoo dua tuaj yeem ua tiav tib lub hom phiaj kawg. Nws yog qhov kev paub txog kev siv dag zog no uas cais cov haujlwm ua haujlwm los ntawm cov khoom seem.
Tom qab ntawd muaj qhov teeb meem ntawm qhov chaw tiav ncaj qha los ntawm lub plhaub ceramic. Cov neeg xav tias classic stainless saib tam sim ntawd tom qab knockout. Qhov koj tau txais yog me ntsis matte, feem ntau scaled nto uas xav tau kev ua haujlwm. Cov ploj wax casting txheej txheem inherently tawm no as-cam khwb cia ntawm daim tawv nqaij. Nws zoo npaum li cas yog nyob ntawm qhov loj ntawm cov ceramic slurry zoo thiab txoj kev de-waxing. Flash dewaxing nyob rau hauv ib qho autoclave yog ib txwm muaj, tab sis yog tias qhov tsis raug tawm, koj tuaj yeem tau txais cov kab nrib pleb uas cia cov hlau nkag mus, tsim cov qhov ntxhib, fused me ntsis uas yog npau suav phem rau tshuab tom qab.
Hais txog machining, qhov ntawd yog qhov uas tus khub muaj peev xwm ua haujlwm puv ntoob ua qhov tseem ceeb. Ib lub tuam txhab zoo li Qingdao Qiangsenyuan Technology (QSY) highlight qhov no zoo. Lawv tsis yog ua tus xwb peev casting; lawv tau txais ntau xyoo hauv CNC machining ib yam nkaus. Qhov no loj heev. Vim hais tias thaum koj tab tom soj ntsuam nrog stainless hlau castings, tshwj xeeb tshaj yog rau precision Cheebtsam, koj yuav luag ib txwm yuav xav tau tom qab-casting CNC ua hauj lwm. Muaj nws tag nrho nyob rau hauv ib lub ru tsev txhais tau tias lawv nkag siab txog qhov kev ntxhov siab hauv qhov casting, muaj peev xwm nyuaj me ntsis los ntawm chilling, thiab tuaj yeem npaj cov txheej txheem machining raws li. Nws zam qhov kev ua si liam ntawm cais casting thiab machining khw.
Qhov twg cov txheej txheem tom qab: Gating thiab Shrinkage
Gating tsim rau stainless hauv poob ciab yog ntau kos duab tshaj science. Koj tab tom sib ntaus sib tua shrinkage, uas tseem ceeb nrog stainless. Cov rooj vag tsis yog cov channel rau hlau xwb; lawv nyob nraum reservoir ntawm molten hlau uas pub lub casting li nws solidifies, tiv thaiv shrinkage porosity. Yog tias lawv me dhau los yog muab tso rau hauv qhov tsis raug, koj yuav tau txais porosity hauv cov ntu tuab. Loj dhau, thiab koj tsim cov dab dej kub heev uas cuam tshuam rau ib feem lossis tsim cov kab noj hniav hauv lub rooj vag nws tus kheej, uas tuaj yeem mus rau hauv qhov casting.
Kuv nco qab ib pawg ntawm lub cev valve ob peb xyoos dhau los. Lub geometry yog complex, nrog ib tug hnyav flange ntawm ib kawg. Thawj tus qauv ntoo uas peb ua tau muaj qhov rooj sab saum toj. Qhov tshwm sim? Shrinkage porosity txoj cai nyob rau hauv lub flange mounting lub ntsej muag. Peb yuav tsum rov qab mus, rov tsim kho tsob ntoo kom siv hnyav dua, muab cov phiaj xwm tso rau lub rooj vag uas ua raws li cov khoom noj, thiab hloov mus rau hauv qab-qhov rooj kaw lus kom muaj kev sib haum xeeb ntau dua. Nws ntxiv tus nqi rau tus qauv, tab sis nws yog tib txoj hauv kev kom tau txais lub suab nrov. Qhov no yog hom kev rov ua dua, kev paub dhau los tweak uas koj yuav tsis pom hauv phau ntawv.
Lwm subtlety yog lub plhaub ceramic nws tus kheej. Rau stainless, koj feem ntau xav tau ib tug prime slurry nrog ib tug zoo zircon hmoov kom tau ib tug du nto tiav uas minimizes tu. Tab sis lub tsho tiv no yuav tsum tau muaj zog vim tias stainless yog hnyav thiab nchuav ntawm qhov kub thiab txias. Lub thermal shock thaum lub 1500 ° C + hlau tsoo lub plhaub yog lim hiam. Lub plhaub uas nyias dhau los yog tsis raug rho tawm haujlwm yuav tawg. Lub plhaub uas tuab heev yuav tsis ua kom zoo, ua rau muaj roj nkag mus. Nws yog qhov sib npaug, thiab qee zaum koj tsuas pom daim ntawv qhia txoj cai rau ib feem zoo los ntawm kev sim ncuav los yog ob.
Tom qab Casting: Cov Kauj Ruam Ua-los-Tsev
Knockout thiab txiav tawm yog qhov uas koj tuav koj ua pa. Koj pom cov khoom nyoos casting, tseem txuas rau nws lub rooj vag system. Nrog stainless, koj tsis tuaj yeem tuav nws tawm nrog rauj; koj raug mob khaub thuas. Cov txheej txheem cua sov zoo li ntshav los yog abrasive txiav yog tus qauv, tab sis koj yuav tsum tau ceev faj kom tsis txhob hloov cov cua kub ntau dhau mus rau hauv lub cev casting, uas tuaj yeem cuam tshuam rau cov metallurgy hauv cheeb tsam kub-tshuaj, tshwj xeeb tshaj yog tias nws yog qib stabilized.
Kev kho cua sov feem ntau tsis yog xaiv tau. Rau feem ntau austenitic stainless castings, koj xav tau ib qho kev kho annealing - cua sov rau ib ncig ntawm ° C thiab ces quenching sai. Qhov no dissolves tej chromium carbides uas tej zaum yuav tau precipitated ntawm grain ciam thaum lub sij hawm txias, uas yog tsis kho, ua rau rhiab heev thiab ua rau corrosion tsis ua hauj lwm. Tab sis sai quenching ntawm ib tug complex, nyias-walled casting? Qhov ntawd yog ib qho kev caw rau distortion. Lub fixturing thaum kho cua sov ua ib qho tseem ceeb raws li lub voj voog nws tus kheej. Lub khw uas nkag siab qhov no, zoo li QSY nrog lawv cov kev sib xyaw ua ke CNC machining thiab casting mus kom ze, tuaj yeem tsim ib feem thiab txheej txheem kom haum lossis kho rau qhov kev xav tau no.
Thaum kawg, kev tshuaj xyuas thiab ua tiav. Dye penetrant testing yog koj tus phooj ywg zoo tshaj plaws los nrhiav qhov tsis xws luag. Rau cov tsis muaj chlorine, koj yuav tsum siv cov tshuaj tsis muaj chlorine penetrant kom tsis txhob muaj kev xeb. Kev sib tsoo thiab polishing yog siv zog heev. Koj pib nrog ntxhib grit kom tshem tawm lub qhov rooj stubs thiab nto imperfections, tab sis koj yuav tsum tau ceev faj. Ib qho kev sib tsoo kub hnyiab los yog embedded hlau los ntawm lub log tsis huv tuaj yeem xeb tom qab, ua rau cov hlau tsis muaj zog corrosion. Nws yog ib qho kev nthuav dav-oriented, qeeb txheej txheem uas automation tseem tawm tsam nrog rau cov geometry nyuaj.
Kev koom ua ke nrog Machining: Lub Ntiaj Teb tiag tiag ua haujlwm
Qhov no yog qhov uas cov lus cog tseg ntawm poob ciab casting stainless hlau twb paub lawm tiag. Qhov ze-net-puab muaj peev xwm yog qhov zoo heev rau kev txo qis machining pov tseg ntawm cov alloys kim. Tab sis ze-net-zoo tsis yog net-zoo. Koj ib txwm tawm Tshuag rau machining. Ntau npaum li cas? Qhov ntawd yog qhov kev txiav txim hu. Tsawg dhau, thiab me ntsis kev hloov pauv los yog qhov tsis zoo ntawm qhov chaw txhais tau hais tias qhov tsis zoo. Ntau dhau lawm, thiab koj nyob nraum nkim lub sij hawm machining thiab cuab yeej lub neej ntawm nyuaj stainless.
Ib tug zoo foundry yuav ua hauj lwm nrog machinist txij thaum pib. Lawv mam li sib tham txog cov ntsiab lus rau machining. Feem ntau, koj yuav tsim cov ntaub qhwv tshwj xeeb lossis cov yam ntxwv rau ntawm cov casting uas tsis yog qhov tseem ceeb tab sis muab qhov chaw huv, txhim khu kev qha rau lub tshuab CNC kom clamp thiab siv los ntawm.
