Thaum cov neeg feem coob hnov 'kev nqis peev casting kev pab cuam', lawv pom ib daim ntawv qhia glossy nrog ci iab, qhov nyuaj. Qhov tseeb, kev sib tsoo txhua hnub ntawm nws, yog deb messier thiab nthuav ntau dua. Muaj ib qho kev xav tsis zoo uas nws yog txhua yam txog kev ua tiav nyob ze-net zoo li thiab qhov ntawd yog nws. Tab sis tus nqi tiag tiag, qhov uas ua rau cov kws tsim khoom thiab cov neeg saib xyuas kev yuav khoom thaum hmo ntuj, tsis yog cov duab xwb - nws yog kev ncaj ncees ntawm cov duab ntawd hauv cov khoom tsim nyog, batch tom qab batch, tsis muaj qhov ua yeeb yam. Qhov ntawd yog qhov uas ntau xyoo ntawm kev ua haujlwm nti, tsis yog xyoo ntawm kev paub, tuaj rau hauv kev ua si.
Lub Plhaub Game: Nws yog ntau tshaj li Xuab zeb
Txhua tus neeg hauv kev lag luam tham txog lub plhaub pwm txheej txheem. Nws yog lub plawv ntawm peev casting. Tab sis dab ntxwg nyoog yog nyob rau hauv lub slurry viscosity, lub stucco xuab zeb grain loj, thiab qhov chaw ziab. Kuv nco qab txog ib qhov project rau lub turbine hniav qauv uas lub plhaub khaws cia tawg thaum lub sij hawm dewaxing. Cov qauv siv quav ciab zoo meej, tus qauv tsim yog suab, tab sis peb tau poob txog 30% ntawm cov plhaub. Qhov teeb meem tsis yog lub tsho loj; nws yog kev tswj cov av noo thaum lub sij hawm ziab ntawm lub tsho tiv no. Kev hloov pauv me ntsis raws caij nyoog peb tsis tau them tag nrho rau. Nws yog cov unglamorous, ib puag ncig yam uas yuav derail lub sij hawm. Lub khw uas tau dhau los ntawm lub caij nyoog txaus, xws li Qingdao Qiangsenyuan Technology Co., Ltd.(QSY) nrog lawv cov 30-xyoo khiav, muaj peev xwm ci cov lus qhia rau hauv lawv cov txheej txheem kev khiav hauj lwm. Lawv tsis yog tsim lub plhaub xwb; Lawv tswj hwm microclimate.
Cov khoom xaiv tau txais kev sib tshuam ntawm no thiab. Koj tsis tuaj yeem nplawm ib qho alloy rau hauv ib lub plhaub system. Piv txwv li, pouring high-temperature npib tsib xee-raws li alloys yuav tsum tau ib tug txawv plhaub refractory formulation tshaj tus qauv 316 stainless hlau. Lub thermal expansion mismatch yuav ua rau lub plhaub spalling los yog hlau nkag. Kuv tau pom cov khoom tawm tuaj nrog qhov ntxhib, gritty nto vim tias lub plhaub tsis tau haum rau cov alloy qhov kub thiab txias. Nws yog ib qho kev hloov maj mam ntawm kev ua tsis tiav uas cais cov khoom lag luam los ntawm tus kws tshaj lij.
Qhov no yog qhov uas cov lus cog tseg ntawm 'cov geometries nyuaj' ua tau raws li qhov tseeb ntawm lub hauv pem teb foundry. Qhov kev sib txawv ntawm sab hauv channel koj tsim? Nws tsuas yog siv tau yog tias cov tub ntxhais ceramic tuaj yeem tso siab tau thiab tom qab ntawd tshem tawm tag nrho tom qab-casting. Peb ib zaug muaj ib lub cev valve nrog ib tug tortuous internal passage. Lub casting yog qhov zoo nkauj, tab sis peb siv ntau dua ntawm kev tshem tawm ultrasonic thiab tshuaj lom neeg ntau dua li ntawm qhov casting nws tus kheej. Ib qho zoo peev casting kev pab cuam tus kws kho mob yuav chij qhov no thaum ntxov, tawm tswv yim tsim tweaks rau cov ntsiab lus luam tawm lossis sib tham txog lwm txoj kev siv tshuab los ntawm qhov pib.
Alloys: Tsis yog Tag nrho cov hlau yog tsim sib npaug
Cov npe khoom-cam khwb cia hlau, hlau, stainless, cobalt-raws li, nickel-raws li-zoo nkaus li ncaj nraim ntawm lub vev xaib xws li https://www.tsingtaocnc.com. Tab sis tuav lawv yog dab tsi tab sis. Casting 17-4 PH stainless kom ua tiav qhov xav tau H900 yog ib qho piv txwv classic. Nws tsis yog hais txog cov chemistry yaj; nws yog kev tswj kom txias tom qab lub ncuav thiab tom qab kev kho cua sov lub voj voog. Tau txais qhov ntsuas cua txias tsis raug hauv pwm, thiab nag lossis daus nyuaj tom qab yuav tsis muab koj cov khoom siv tshuab uas koj xav tau. Ib feem yuav dhau qhov kev kuaj pom tab sis ua tsis tiav hauv kev sim qaug zog.
Ua hauj lwm nrog cov alloys tshwj xeeb xws li cobalt-based Stellite lossis Inconel variants yog lwm qhov kev ua si pob. Lawv feem ntau tau teev tseg rau qhov hnyav hnyav lossis corrosion kuj. Cov kev sib tw yog lawv fluidity-los yog tsis muaj. Lawv tsis ntws zoo li txhuas. Koj xav tau superheat siab dua, uas ua rau lub plhaub, thiab feem ntau yuav tsum tau nchuav cov nqi kom tsis txhob ntxov ntxov hauv cov ntu nyias. Gating design ua qhov tseem ceeb heev. Ib lub rooj vag tsis zoo ntawm cov txheej txheem carbon steel yuav tsuas yog muab rau koj lub qhov txhab shrinkage. Ntawm $ 500 / kg cobalt alloy, nws yog kev puas tsuaj loj. Qhov no yog qhov chaw foundry cov kws tshaj lij metallurgical, tsis yog nws lub peev xwm casting, yog qhov tseem ceeb.
Kuv xav tias ntau tus neeg saib xyuas kev muag khoom underestimate tus nqi ntawm lub foundry uas tiag tiag to taub machining. QSY hais txog CNC machining nyob rau hauv tandem nrog casting tsis yog ib tug nqi-ntxiv kev pab cuam; nws yog ib lub cim ntawm kev xav integrated. Lawv paub qhov twg yuav tawm hauv Tshuag rau kev txiav kom huv si, yuav ua li cas qhov kev ntxhov siab casting yuav cuam tshuam rau kev ua haujlwm tsis zoo, thiab qhov chaw twg yog qhov tseem ceeb rau kev ua siab ntev. Casting ib qho ze-net zoo ib feem uas yog unmachinable yog tag nrho cov pov tseg. Ib lub khw sib koom ua ke kawm los ntawm ob tog ntawm cov txheej txheem.
The Handoff: Los ntawm Casting mus rau Finished Part
Qhov no yog theem uas nthuav tawm cov txheej txheem tsis zoo. Ib qho zoo kawg nkaus cam khwb cia tuaj yeem raug puas tsuaj los ntawm kev txhoj puab heev blasting lossis txiav tsis raug ntawm lub rooj vag system. Kuv nco qab ib pawg ntawm stainless hlau fittings qhov twg lub zog tensile ntawm lub rooj vag stump yog hauv qab spec. Lub casting nws tus kheej yog suab, tab sis cov txheej txheem kev txiav tawm ntawm phau ntawv tau tsim kom muaj cua sov hauv zos txaus los cuam tshuam rau microstructure. Qhov kev kho tau hloov mus rau lub dav hlau abrasive lossis cov txheej txheem tswj-band pom nrog kev ua kom txias. Nws yog ib qho kev nthuav dav uas tsis ua rau kev muag khoom, tab sis nws tua cov khoom.
Dimensional soj ntsuam yog lwm minefield. Koj tab tom cuam tshuam nrog cov khoom uas tau dhau los ua cua sov los ntawm ~ 1500 ° C mus rau chav sov. Lawv txav mus. Daim ntawv tshaj tawm kev tshuaj xyuas thawj zaug (FAIR) uas suav nrog CMM cov ntaub ntawv tsis tuaj yeem sib tham rau cov khoom tseem ceeb. Tab sis txawm li ntawd los, koj yuav tsum paub qhov koj ntsuas. Datum cov qauv ntawm kev kos duab kos duab yuav tsum tau ua. Cia siab tias qhov cam khwb cia saum npoo yuav yog qhov ua haujlwm tau zoo rau kev ua kom nruj nruj yog feem ntau nug txog teeb meem. Qee zaum, koj yuav tsum tau siv lub tshuab ua ntej ua ntej, tom qab ntawd tshuaj xyuas lwm yam nta. Ib tus kws kho mob uas thawb rov qab rau qhov kev kos duab tsis muaj tseeb yog ua rau koj txaus siab.
Thaum kawg, muaj logistics ntawm kev sib xws. Lawv puas tuaj yeem tswj tau tib lub tshav kub code rau kev tsim khoom? Lawv puas muaj traceability los ntawm ingot mus rau qhov chaw xa khoom? Rau kev lag luam xws li roj & roj lossis aerospace, qhov no tsis yog xaiv tau. Nws ntxiv cov nqi thiab qhov nyuaj, tab sis ib qho chaw tsim khoom uas tau ua haujlwm nyob rau theem ntawd, yuav ua rau nws nyob rau hauv lawv cov kab ke ntau xyoo, tsis yog qhov kev xav tom qab.
Thaum Nws Mus Tsis Zoo (Thiab Nws Yuav)
Ua tsis tiav yog tus kws qhia zoo tshaj plaws. Thaum ntxov ntawm kuv lub sij hawm cuam tshuam nrog castings, peb tau khiav ntawm lub twj tso kua mis hauv duplex stainless uas tsim micro-cracking. Cov chemistry nyob ntawm spec, cov txheej txheem zoo li tsis hloov. Tom qab kev tshawb nrhiav tus nqi uas cuam tshuam nrog kev tshuaj ntsuam xyuas sab nraud, tus neeg ua txhaum tau taug qab mus rau qhov muaj kab mob me me hauv cov khoom siv rov ua dua tshiab ceramic uas cuam tshuam rau cov cua txias hauv zos. Qhov kev daws teeb meem yog kev tswj hwm nruj dua ntawm cov khoom siv plhaub khoom siv thiab hloov kho lub voj voog hluav taws xob. Lub ntsiab lus yog, tus kws kho mob raws caij nyoog muaj lub tsev qiv ntawv ntawm cov kev ua tsis tiav thiab lawv cov kev daws teeb meem. Lawv tau nqis peev rau hauv cov cuab yeej kuaj mob-spectrometers, ntsuas cua sov, cov khoom siv hluav taws xob-tsis yog nrhiav qhov teeb meem xwb, tab sis nkag siab nws cov hauv paus ntsiab lus.
Lwm qhov pitfall yog qhov 'copy exact' fallacy. Koj xa ib qho piv txwv zoo meej thiab nug rau ib qho kev tsocai los rov ua dua. Yog tsis muaj cov txheej txheem qub-cov ntaub ntawv plhaub tiag tiag, qhov kub thiab txias, kev tsim qauv-koj tab tom thov rau kev rov qab engineering, tsis yog kev tsim tawm. Cov lus tsocai yuav tsawg, tab sis lub voj voog txoj kev loj hlob kom phim cov qauv yuav ntev thiab kim. Nws yog ib txwm zoo dua los pib los ntawm kev luam tawm thiab cov kev xav tau ntawm kev ua haujlwm.
