Thaum ib tug neeg hais tias 'nickel puag', ib nrab ntawm chav xav txog lub dav hlau tshuab, lwm ib nrab xav txog cov khoom kim heev, cov khoom muaj teeb meem uas muaj teeb meem ntau dua li qhov tsim nyog. Qhov tseeb, raws li ib txwm muaj, yog daig qhov chaw nyob hauv qhov chaw ntxhov siab. Nws tsis yog cov mos txwv khawv koob, tab sis tso tseg nws tsuas yog 'kim stainless' yog txoj hauv kev ceev kom xaus nrog qhov ua tsis tiav. Qhov kev sib tw tiag tiag tsis yog hauv kev qhia nws ntawm daim duab; nws yog nyob rau hauv txhiab me ntsis kev txiav txim siab los ntawm lub khw muag khoom mus rau qhov kawg machining pass.
Lub ntsiab lus yuam kev: Nws yog txhua yam hais txog cua sov
Feem ntau cov ntawv specs coj nrog kev ua haujlwm siab, thiab qhov ntawd tsis yog lawm. Tab sis tsuas yog tsom mus rau qhov 1200 ° F tensile lub zog yog qhov chaw pib ua haujlwm. Kuv twb pom designs uas nplawm ntawm ib npib tsib xee base alloy zoo li Inconel 718 vim tias qhov kev khiav hauj lwm kub siab, tsuas yog ua tsis tau los ntawm cov tshuaj chloride-vim kev ntxhov siab corrosion tawg ntawm qhov qis dua, qhov kub tsis xav txog. Lub alloy yog 'overqualified' rau tshav kub tab sis underqualified rau lub tiag tiag tshuaj ib puag ncig. Zaj lus qhia? Lub thermal profile tsuas yog tshooj ib. Koj xav tau tag nrho cov corrosion thiab mechanical zaj dab neeg.
Tom qab ntawd muaj cov lus dab neeg ntawm weldability. Nug tus kws tsim khoom yog tias lawv tuaj yeem txuas tau, lawv yuav hais tau. Tab sis lawv puas tuaj yeem txuas nws thiab muaj thaj chaw muaj kev kub ntxhov khaws cov khoom koj tsim rau? Qhov ntawd yog kev sib tham sib txawv. Tom qab-weld kev kho cua sov rau cov alloys no tsis yog ib qho kev pom zoo; nws yog feem ntau qhov sib txawv ntawm lub suab sib dhos thiab lub teb tawg tos kom tshwm sim. Peb tau kawm qhov no txoj kev nyuaj ntawm qhov project manifold xyoo rov qab, piv txwv li tus neeg muag khoom tus qauv PWHT yuav txaus. Nws tsis tau. Lub voj voog hluav taws xob tau tawm, thiab peb tau xaus nrog lub sijhawm ntxov ntxov oxidation ciam teb.
Qhov no yog qhov uas tus khub qhov chaw tsim khoom thiab kev siv tshuab ua haujlwm tsis tuaj yeem sib tham. Nws tsis yog hais txog kev yuav khoom casting; nws yog hais txog kev yuav cov txheej txheem tswj. Ib lub tuam txhab zoo li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nrog lawv peb lub xyoo caum hauv plhaub thiab peev casting, tau txais qhov no. Thaum koj tau nchuav npib tsib xee base alloys ntev li ntawd, koj tau tsim ib lub tsev qiv ntawv ntawm cov keeb kwm thermal, kev tsim qauv, thiab cov tswv yim pub mis tshwj xeeb rau cov ntaub ntawv finicky. Koj tuaj yeem nrhiav lawv ntawm https://www.tsingtaocnc.com. Lawv cov ntaub ntawv tsis yog ib daim ntawv teev cov khoom siv xwb; Nws yog cov ntaub ntawv ntawm kev daws teeb meem hauv cobalt thiab nickel alloys.
Los ntawm Melt mus rau Machining: Tus nqi tiag tiag tsav tsheb
Cia peb tham txog machining, vim hais tias qhov ntawd yog qhov uas cov peev nyiaj ntsiag to los ntshav. Cov neeg saib cov khoom siv raw tus nqi ib kilo thiab gasp. Tom qab ntawd lawv tau txais thawj machining quote thiab tiag tiag gasp. Nickel puag alloys zoo li Hastelloy X lossis Waspaloy ua hauj lwm nyuaj zoo li tsis muaj lwm yam. Ib lub cuab yeej blunt lossis tus nqi noj tsis txaus tsis yog ua rau koj qeeb; nws tsim cov tawv nqaij tawv uas ua rau qhov kev hla dhau mus txawm nyuaj, muaj feem cuam tshuam rau qhov.
Lub tswv yim yog aggression, uas suab counterintuitive. Koj xav tau ntse, premium-qib carbide, siab rigidity nyob rau hauv koj teeb, thiab koj yuav tsum tau nyob rau hauv uas ua hauj lwm-hardened txheej nyob rau hauv ib mus. Lub teeb, skimming txiav yog tus yeeb ncuab. Peb ib zaug sim txuag ntawm cov cuab yeej rau ib pawg ntawm Alloy 625 brackets, siv ib qho me ntsis reground ntxig. Lub sij hawm voj voog ob npaug, peb tau hlawv peb zaug raws li ntau qhov ntxig, thiab qhov ua tiav saum npoo tsis tuaj yeem lees txais. Qhov 'savings' raug nqi ntau rau peb hauv lub sijhawm tshuab thiab rov ua haujlwm dua.
Qhov no yog vim li cas cov khw sib koom ua ke muaj ntug. Yog hais tias tib lub koom haum uas cam khwb cia ib feem kuj tshuab nws ntawm lawv CNCs, lawv twb tau optimized thawj cov nyiaj pub dawb. Lawv paub qhov tseeb ntawm qhov chaw ntawm lawv qhov chaw ua haujlwm. Tsis muaj tus ntiv tes taw ntawm qhov chaw tsim khoom thiab lub khw muag khoom thaum lub cuab yeej tawg. Ntawm QSY, lawv ua ke casting thiab CNC machining muaj peev xwm txhais tau tias lawv tab tom xav txog qhov kawg txiav thaum lub sij hawm tsim pwm. Qhov kev sib dhos ntawd tsis muaj nuj nqis rau kev tswj hwm tus nqi kawg.
Alloy nyob rau hauv lub Alloy: Cov ntsiab lus tseem ceeb
Kev qhia txog Inconel 718 tsuas yog pib. Puas yog AMS 5662? AWS 5663 Qhov sib txawv yog nyob rau hauv qhov tso cai rau txhuas, titanium, thiab niobium. Cov ob peb feem kaum ntawm ib feem pua hais cov lus teb kev laus thiab lub zog kawg. Hauv daim ntawv thov kev ncaj ncees, koj tsis tau yuav 718 generic; koj tab tom yuav ib qho tshwj xeeb yaj chemistry thiab daim ntawv qhia txog kev kho cua sov.
Kuv nco qab qhov kev hloov pauv hloov pauv uas yuav luag ua rau raug kaw. Ib feem tau ntawv pov thawj raws li 718, tab sis nws yog me ntsis off-spec yaj optimized forgeability, tsis yog qhov kub-kub stability peb xav tau. Nws dhau ntawm chav tsev-temp mechanicals, tab sis nyob rau hauv load ntawm 1000 ° F, tus nqi nkag tau tawm ntawm spec. Qhov kev soj ntsuam tsis ua haujlwm tau taug qab nws rov qab rau Al / Ti piv. Tam sim no, peb ib txwm hais meej qhov tseeb AMS lossis tus tswv yaj cov cai thiab thov cov ntawv pov thawj zeb uas qhia qhov tseeb chemistry, tsis yog tias nws yog 'hauv spec'.
Qib ntawm traceability no yog lub hauv paus rau txhua tus neeg xa khoom loj. Nws yog qhov tho txawv, cov ntaub ntawv-hnyav sab ntawm kev ua haujlwm nrog npib tsib xee base alloys uas cais cov khoom ua haujlwm los ntawm cov uas tsis ua haujlwm ntsiag to. Ib tug foundry qhov zoo system tsis yog ib tug admin feature; nws yog cov cuab yeej tsim khoom.
Thaum Yuav Siv Nws (Thiab Thaum Yuav Taug Kev)
Qhov zoo tshaj plaws npib tsib xee base daim ntawv thov kuv puas tau ua haujlwm yog ib txheej ntawm cov thermowells rau chav hloov kho catalytic. Ib puag ncig yog hydrogen sulfide, high-pressure hydrogen, thiab cyclic temps mus txog 950 ° F. Stainless hlau yuav corroded los yog embritted nyob rau hauv lub hlis. Lub qhov dej Inconel 600 tau siv sijhawm ntau xyoo. Cov xwm txheej zoo kawg nkaus phim cov hlau alloy lub peev xwm: hnyav corrosion thiab kub kub.
Qhov phem tshaj plaws yog ib qho kev sib koom ua ke nyob rau hauv ib qho me me corrosive, ambient-temperature washdown ib puag ncig. Tus neeg siv khoom muaj 'nickel alloy' nyob rau hauv lawv cov qauv rau qhov tseem ceeb thiab tsis kam budge. Peb siv Alloy 276. Nws ua haujlwm flawlessly, tab sis tus nqi yog absurd. Lub super duplex stainless hlau yuav tau ua txoj haujlwm rau ib feem peb ntawm tus nqi. Tsis txhob cia ib tug specification ua kev ntseeg. Ntsuas qhov chaw ua haujlwm tiag tiag ua ntej.
Qhov no yog qhov kev txiav txim zoo uas los ntawm kev pom cov ntu hauv kev pabcuam. Nws tsis yog tsuas yog hais txog qhov alloy tuaj yeem ua tau; nws yog hais txog seb nws lub peev xwm tshwj xeeb tsim nyog rau txoj haujlwm. Qee lub sij hawm, cov kws tshaj lij tshaj plaws yog xav kom cov khoom pheej yig dua, tsim nyog dua.
Lub neej yav tom ntej tsis yog cov Alloys tshiab xwb
Muaj ntau lub suab nrov txog cov hmoov metallurgy tshiab npib tsib xee base superalloys, thiab lawv yog impressive. Tab sis rau feem ntau cov ntawv thov kev lag luam, cov txiaj ntsig loj dua yog nyob rau hauv cov txheej txheem kev ntseeg tau thiab tsim rau kev tsim khoom. Peb puas tuaj yeem tsim cov cua txias kom yooj yim rau hauv qhov casting kom tsis txhob muaj kev sib dhos brazed? Peb puas tuaj yeem kho lub vojvoog fillet kom tshem tawm cov kauj ruam machining thiab kev ntxhov siab?
Kev sib koom tes ntawm kev tsim thiab kev tsim khoom yuav tsum nruj. Xa ib daim duab tiav, tsis tuaj yeem-rau-cam khwb cia rau hauv qhov chaw tsim khoom thiab thov rau qhov kev tsocai yog qhov pib tsis zoo. Kev koom tes nrog cov kws tshaj lij xws li QSY thaum ntxov, thaum tsim qauv tseem muaj dej, tso cai rau lawv tawm tswv yim kev hloov kho rau lub suab thiab kev ua haujlwm. Lawv qhov kev paub dhau los nrum hlau, hlau, thiab tshwj xeeb alloys muab lawv txoj kev xav dav dav txog qhov uas tsis sib haum xeeb txog txoj haujlwm nickel puag.
Thaum kawg, kev ua haujlwm zoo nrog cov ntaub ntawv no yog hais txog kev hwm lawv qhov nyuaj yam tsis muaj kev ntshai los ntawm nws. Nws yog ib qho kev sib xyaw ntawm kev tshawb fawb nruj heev - tshuaj xyuas cov ntawv pov thawj zeb, ua qauv kev ruaj ntseg - thiab yuav luag zoo nkauj hauv khw hauv pem teb, zoo li paub lub suab meej lub cuab yeej yuav tsum ua thaum nws txiav Inconel txoj cai. Qhov kev sib xyaw ntawd yog qhov hloov cov khoom siv nyuaj rau hauv kev daws teeb meem.
