Txhua leej txhua tus tham txog Inconel 625 zoo li nws yog cov mos txwv khawv koob rau kev kub siab corrosion. Nws yog, feem ntau. Tab sis yog tias koj tau ua tiag tiag machined, welded, los yog sourced ib tug casting nyob rau hauv nws, koj paub tias cov khawv koob los nrog ib tug loj se. Nws tsis yog 'super alloy' xwb; nws yog kev cog lus.
Lub Hype vs. Tshuab dhos
Koj pom daim ntawv spec: zoo heev oxidation kuj mus txog 1800 ° F, zoo zog, yadda yadda. Qhov lawv tsis muaj xov xwm yog li cas nws ua haujlwm hnyav. Koj coj ib tug zoo nkauj, ntse cuab tam rau hauv ib tug txiav rau Ib 625, tau txais cov nti zoo mus, thiab mam li nco dheev koj tsis txiav ntxiv lawm - koj tsuas yog rub tawm thiab tsim kom muaj cua sov txaus kom muag koj lub cuab yeej, tsis yog lub workpiece. Qhov saum npoo tau nyuaj dua li thaum koj pib. Kuv tau pom cov teeb tsa uas ua haujlwm zoo kawg nkaus ntawm 316L tsuas yog tau rhuav tshem. Koj xav tau cov cav tov nruj, qhov zoo rake geometries, thiab cov hlab ntsha kom khiav qeeb qeeb nrog hnyav dua, zoo ib yam. Hesitation yog kev tuag.
Coolant tsis yog xaiv tau, nws yog tswv yim. Koj xav tau kev kub siab kom tau txais nws txoj cai mus rau qhov txiav kom tawg lub tshav kub barrier thiab ntxuav cov chips. Yog tias chips recut, nws yog qhov kev ua si dhau rau qhov kawg thiab cov cuab yeej. Kuv nco qab ib txoj hauj lwm uas peb tau machining lub valve loj lub cev los ntawm ib Ib 625 casting. Peb xav tias peb muaj nws hu rau hauv, tab sis ntawm qhov kawg boring pass, ib tug stringy nti qhwv ib ncig ntawm lub bar. Nws tau tso lub cim rau ntawm tus ID phem heev uas peb yuav tsum tau muab pov tseg. $ 20,000 zaj lus qhia hauv kev tswj chip.
Thiab kev tsim cov khoom lag luam lossis cov khoom lag luam tseem ceeb. Tsis yog tag nrho 625 yog tsim sib npaug. Kev xyaum yaj, cov qauv nplej-nws cuam tshuam rau kev ua haujlwm loj heev. Ib qho ntxeem tau casting yuav rhuav tshem cov cuab yeej sai dua li koj tuaj yeem hais tias ntxig qib. Koj xav tau tus neeg muag khoom uas nkag siab qhov no los ntawm qhov chaw tsim khoom, tsis yog lub tsev khaws khoom nrog lub saw bar.
Vuam: Qhov Kev Xeem Chemistry tshwm sim
Vuam Ib 625 tsawg dua txog kev koom nrog thiab ntau ntxiv txog kev khaws cia nws cov khoom. Tus yeeb ncuab loj yog carbide nag lossis daus nyob rau hauv tshav kub-cuam tshuam cheeb tsam (HAZ). Koj tau txais nws kub ntev dhau lawm, thiab chromium carbides tsim raws cov kab lis kev cai. Dheev, koj cov khoom xav tsis thoob corrosion-resistant muaj ib txoj hauv kev zoo me me rau kev tawm tsam ntawm ib sab ntawm lub vuam. Nws zoo nkaus li zoo, tab sis nws yuav ua tsis tiav hauv kev pabcuam.
Koj xav tau kev tswj nruj ntawm cov khoom siv hluav taws xob. Tsawg amperage, stringer hlaws, ntau nres kom cia nws txias. Thiab koj yuav tsum siv qhov muab tub lim zoo-feem ntau 625 muab tub lim hlau nws tus kheej lossis qee zaum ERNiCrMo-3. Siv cov khoom siv stainless hlau vim tias nws siv tau yog qhov lav tsis tau. Kuv tau pom cov hauj lwm kho ntawm lub twj tso kua mis uas ib tug neeg ua li ntawd. Lub weld tuav lub siab, tab sis nws tawg los ntawm chloride kev nyuaj siab corrosion nyob rau hauv rau lub hlis. Lub post-mortem pom cov kab stark qhov twg chemistry hloov.
Kev ntxuav ua ntej thiab tom qab vuam yog kev ntseeg. Tsis muaj roj, tsis muaj sulfur, tsis muaj dab tsi. Txhua yam kab mob kis tau mus rau hauv lub pas dej ua ke thiab ua rau cov theem nkig. Nws yog qib huv uas xav tias phais.
Casting Conundrum
Tau txais lub suab nrov hauv Ib 625 yog art. Cov hlau muaj qhov khov ntev ntev, uas ua rau nws yooj yim rau micro-porosity thiab kub tearing yog tias lub rooj vag thiab nce siab tsis zoo tag nrho. Koj tsis tuaj yeem nchuav nws li cam khwb cia hlau. Lub foundry yuav tsum tau tswj cov pwm kub, lub ncuav tus nqi, txhua yam.
Qhov no yog qhov kev paub dhau los ntau xyoo suav tiag tiag. Ib lub tuam txhab zoo li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nrog rau lawv 30 xyoo nyob rau hauv lub plhaub thiab peev casting, yuav tau txhim tsa qhov kev paub tshwj xeeb. Lawv yuav paub yuav ua li cas taw qhia lub vaj tse nyob hauv cov pwm kom txo qis kev ntxhov siab, lossis yuav ua li cas los tsim cov txheej txheem pub rau cov tuab flange hloov mus rau phab ntsa nyias. Nws yog pab pawg neeg paub koj tsis tuaj yeem tau txais los ntawm phau ntawv.
Lawv keeb kwm hauv Nickel-raws li alloys thiab CNC machining yog qhov tseem ceeb. Lawv tsis yog ua ib qho duab xwb; lawv tab tom xav txog qhov kawg yuav ua li cas thiab welded. Lawv puas tso cov khoom lag luam txaus rau ntawm lub ntsej muag tseem ceeb? Lawv puas tso txoj kab sib cais kom txo qis kev ua tiav ntawm qhov chaw sib khi? Qhov kev xav sib xyaw ua ke no txuag tau nyiaj poob qis.
Thaum Yuav Siv Nws (Thiab Thaum Yuav Taug Kev)
Yog li nrog tag nrho cov mob taub hau no, vim li cas siv nws? Yooj yim: thaum tsis muaj dab tsi muaj sia nyob. Seawater ib puag ncig nrog cov ntsiab lus chloride siab. Flue gas desulfurization systems. High-temperature fasteners raug rau cov roj qaub. Nws yog lub neej ntawd rau qhov tseem ceeb, tsis txav mus rau hauv cov tshuaj lom neeg hnyav / petrochemical chaw.
Tab sis kuv tau thawb rov qab ntawm specs ua ntej. Ib tug neeg xav tau ib tug tag nrho Ib 625 manifold rau kev pabcuam me me organic acid ntawm 300 ° F. Qhov ntawd yog overkill. Peb tau khiav ib lub neej kev txheeb xyuas tus nqi piv nws rau high-moly duplex stainless. Lub duplex yeej ntawm tus nqi pib, tus nqi tsim khoom, thiab yuav kav ntev li 20 xyoo tsim lub neej. Qee lub sij hawm engineers qhia 625 vim nws nyob rau hauv cov npe ntawm cov khoom siv tiv thaiv corrosion, tsis yog vim nws yog qhov kev xaiv nyiaj txiag. Ib feem ntawm txoj haujlwm yog paub thaum twg los qhia txog kev nqis tes ua.
Lwm lub sijhawm taug kev yog thaum tus qauv tsim muaj cov kaum ntse ntse lossis xav tau ib tuj ntawm intricate, sib sib zog nqus machining. Cov kev ntxhov siab uas koj ntxias yuav tsis tsim nyog. Qee lub sij hawm, rov tsim cov khoom sib xyaw kom ua tau ntau dua fabrication-phooj ywg yog ntse dua kev sib ntaus sib tua cov khoom.
Lub Real-World Supply Chain
Koj tsis yog xaj Inconel 625 xwb. Koj tsim nyog tau txais qhov chaw. Rau cov castings, koj tab tom nrhiav ib lub chaw tsim khoom uas tuaj yeem muab cov ntaub ntawv pov thawj uas taug qab rov qab mus rau lub tshav kub, nrog rau tag nrho chemistry thiab mechanicals. Koj tuaj yeem hais qhia koj tus kheej cov txheej txheem kho cua sov - kev daws teeb meem ntawm 2150 ° F ± 25 ° F ua raws li kev tua sai yog tus qauv kom yaj cov carbides teeb meem.
Rau ib tus khub ua haujlwm puv ntoob, koj xav tau ib tus neeg ua haujlwm tag nrho. Saib ntawm QSY lub Scope - los ntawm kev nqis peev casting ntawm lub tshwj xeeb alloys mus rau qhov kawg CNC machining - uas tshem tawm ntau tus ntiv tes taw. Yog tias muaj qhov tsis zoo pom thaum lub sijhawm machining, nws yog nyob ntawm lawv los daws nws, tsis yog kev sib cav ntawm cov foundry thiab lub khw muag khoom. Qhov kev txuas ntxiv ntawd yog qhov loj heev rau qhov nyuaj, muaj txiaj ntsig siab.
Lub sij hawm ua ntej yog ntev. Cov khoom zoo tsis zaum ntawm lub txee. Zoo foundry peev yog booked. Txhua tus neeg cog lus nrawm nrawm yog txiav cov ces kaum, lav. Npaj rau lub hlis, tsis yog lub lis piam.
Thaum kawg, Ib 625 yog ib yam khoom zoo heev uas xav tau kev hwm. Nws tsis yog khoom; Nws yog kev koom tes ntawm tus tsim qauv, metallurgist, foundry, thiab machinist. Tau txais cov saw hlau ntawd, thiab koj tau txais ib qho khoom tivthaiv uas muaj sia nyob ntawm cov nroj tsuag uas nws tau teeb tsa hauv. Nco qhov txuas, thiab koj tau txais daim ntawv hnyav heev. Qhov txawv yog nyob rau hauv gritty, unglamorous cov ntsiab lus ntawm yuav ua li cas nws tau ua.
