Thaum koj hnov 'Incoloy washer', qhov kev xav tam sim rau ntau tus tsuas yog lub siab kub, lub tshuab ntxhua khaub ncaws zoo rau qhov chaw kub. Qhov ntawd yog qhov pitfall. Hauv kev muaj tiag, qhia txog txoj cai Incoloy ntxhua khaub ncaws tsawg dua ntawm qhov ntsuas kub ntawm daim ntawv qhia thiab ntau ntxiv txog cov dej cawv tshwj xeeb ntawm chlorides, sulfides, thiab thermal cycling hauv qhov chaw pabcuam tiag tiag. Kuv tau pom tej yaam num uas cov khoom qib yog technically raug, tab sis qhov tsis ua hauj lwm los ntawm cov txheej txheem machining hloov qhov kev ncaj ncees saum npoo, tsim ib txoj hauv kev rau kev ntxhov siab corrosion cracking. Nws yeej tsis yog ib lub tshuab ntxhua khaub ncaws xwb.
Cov ntaub ntawv tshawb fawb: Ntau tshaj Incoloy 800H
Txhua tus neeg ua haujlwm rau 800H lossis 825 rau cov tshuab ntxhua khaub ncaws. Lawv yog cov neeg ua haujlwm. Tab sis nyob rau hauv high-chloride, low-pH scrubber system peb tau ua haujlwm, 800H pom cov tsos mob ntawm pitting tom qab 14 lub hlis. Cov neeg siv khoom npau taws heev-lawv tau them nyiaj rau cov khoom kim heev. Qhov teeb meem? Lub tshuab ntxhua khaub ncaws geometry. Nws yog tus qauv tiaj tus ntxhua khaub ncaws, uas tsim ib qho kev sib tw. Nyob rau hauv lub microenvironment stagnation, lub chemistry tau hloov, thiab cov hlau tsis muaj zog tsis txaus. Peb kawm qhov ntawd nrog Incoloy ntxhua khaub ncaws daim ntawv thov, koj yuav tsum qhia qhov chaw nyob rau hauv microscopic nthuav dav: nws puas yog tag nrho raus, puas muaj cyclic ntub / qhuav, puas muaj deposit buildup?
Qhov ntawd yog qhov uas alloy nuance tseem ceeb. Rau qhov kev txhuam txhuam rov qab, peb tau tsiv mus rau Incoloy 625 ntxhua khaub ncaws. Cov ntsiab lus molybdenum siab dua yog qhov tseem ceeb rau qhov tshwj xeeb pitting kuj. Tab sis nws tsis yog universal upgrade. 625 yog qhov nyuaj rau lub tshuab, kim dua, thiab rau cov qauv flue gas ductwork, nws yog overkill. Koj mus nkim nyiaj. Kev txiav txim hu xov tooj yog nyob rau hauv kev paub txog qhov sib txawv ntawm cov kev pab cuam kub-kub thiab ib tug localized corrosion ntxiab.
Kuv nco qab nrhiav cov 625 lub tshuab ntxhua khaub ncaws no rau kev ua haujlwm nrawm. Tus neeg muag khoom ib txwm tau rov qab los. Peb pom ib tus neeg muag khoom tshiab cog lus nrawm nrawm. Cov tshuab ntxhua khaub ncaws tuaj txog, qhov ntev tau zoo meej, tab sis qhov ua tiav saum npoo tsis yog lawm - du heev, yuav luag polished. Nws tsa ib tug chij liab. Polished nto ntawm a Incoloy ntxhua khaub ncaws Qee zaum tuaj yeem txo qhov kev sib txhuam coefficient hauv kev sib koom ua ke bolted, uas tuaj yeem cuam tshuam cov clamp load hauv thermal expansion. Peb yuav tsum muab lawv tso rau hauv vibratory finisher kom tau txoj cai, uniform matte tiav. Nws ncua peb ob hnub. Zaj lus qhia? Daim ntawv spec tsis sau txhua yam. Deg kev ntxhib los mos tseem ceeb rau kev ua haujlwm, tsis yog kev zoo nkauj xwb.
Manufacturing Realities: Los ntawm Casting rau CNC
Qhov no yog qhov uas cov roj hmab tau raws txoj kev. Koj tsis tuaj yeem thwj cov no zoo li tus qauv steel ntxhua khaub ncaws. Feem ntau kev ua haujlwm siab Incoloy ntxhua khaub ncaws Cheebtsam pib raws li peev castings los yog machined los ntawm wrought bar. Rau loj-inch los yog tsis-tus qauv thickness washers, casting yog feem ntau pheej yig dua. Kuv tau ua haujlwm nrog Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) ntawm ntau qhov haujlwm uas yuav tsum tau muaj cov khoom siv alloy. Lawv peb caug xyoo nyob rau hauv plhaub pwm thiab peev casting, tshwj xeeb nrog cov nickel-raws li alloys, qhia nyob rau hauv lawv cov txheej txheem tswj. Lawv nkag siab tias rau Incoloy, kev kho cua sov tom qab casting yog qhov tseem ceeb raws li cov chemical yaj. Ib qho kev tswj tsis zoo ntawm lub voj voog annealing tuaj yeem ua rau koj muaj kev cuam tshuam ntawm cov kab lis kev cai, ib txoj hauv kev zoo tshaj plaws rau kev xeb.
CNC machining yog lwm txoj hauv kev, tshwj xeeb tshaj yog rau cov qauv lossis cov khoom me me uas koj xav tau kev tswj xyuas meej ntawm cov khoom siv wrought. Qhov kev sib tw ntawm no yog kev ua haujlwm hnyav. Incoloy alloys muaj npe nrov rau nws. Koj dhau mus nrog tus nqi pub mis tsis raug lossis lub cuab yeej npub, thiab koj tau ua kom tawv nqaij, ua rau kev txiav tom ntej nyuaj thiab muaj peev xwm ua rau micro-cracks. Kuv twb ruined ob peb blanks kawm qhov no. Cov machinists ntawm cov khw xws li QSY, uas sau CNC machining ntawm cov alloys tshwj xeeb raws li qhov tseem ceeb muaj peev xwm, tau txais qhov no. Lawv siv cov cuab yeej tshwj xeeb geometry, lub siab txias txias, thiab tswj tsis tau. Nws tsis yog khiav ib qho program xwb; nws yog tswj cov khoom tus cwj pwm.
Muaj kev ua tsis tiav uas nrog kuv. Peb xav tau ib lub tshuab ntxhua khaub ncaws tuab rau lub reactor taub hau kaw. Cov luam ntawv hu ua Incoloy 718, machined los ntawm bar Tshuag. Lub khw tau xa cov khoom uas ua tau raws li txhua qhov kev kuaj xyuas. Tab sis thaum lub sij hawm installation, ob peb lub tshuab ntxhua khaub ncaws tawg thaum torqued. Lub hauv paus ua rau? Cov khoom lag luam bar muaj cov qauv tsis sib xws ntawm cov zeb, thiab cov txheej txheem machining tsis suav rau nws. Kev ntxhov siab ntawm machining, ua ke nrog cov ntawv thov torque, pom txoj kev tsis muaj zog. Peb yuav tsum tau hloov mus rau lub nplhaib forged dawb paug, uas muaj ntau homogeneous qauv, thiab rov tshuab dua. Tus nqi thiab ncua sij hawm yog qhov tseem ceeb. Nws tau qhia kuv tias lub hauv paus ntawm cov khoom siv raw-bar, forging, casting-yog qhov tseem ceeb ntawm cov khoom Incoloy ntxhua khaub ncaws specification uas feem ntau overlooked ntawm kev yuav khoom.
Qhov Specification Gap: Dab tsi Drawings Tsis Qhia
Engineering drawings yog txaus ntshai ntawm conveying ntsiab lus. Lawv yuav qhia Incoloy 600, ASTM B166 thiab hardness ntau yam. Tab sis lawv tsis tshua muaj qhov yuav tsum tau kuaj corrosion rau qhov ua tiav, zoo li ASTM G28 Txoj Kev A rau intergranular nres. Rau ib Incoloy ntxhua khaub ncaws zaum hauv lub caj dab weld flange ntawm kab sulfuric acid, qhov kev sim no tsuas yog lav nws yuav tsis tig mus rau Swiss cheese hauv ib xyoos. Tam sim no kuv ua ib qho taw qhia ntxiv rau daim ntawv: Cov ntaub ntawv pov thawj yuav tsum suav nrog ASTM G28 cov txiaj ntsig rau cov cua sov siv. Nws lim tawm cov chaw muag khoom uas tsuas yog cov khoom lag luam.
Lwm qhov uas ploj lawm spec yog flatness thiab parallelism tshaj tag nrho saum npoo. Rau ib tug mos mos gasket, nws tsis tshua tseem ceeb. Tab sis rau lub tshuab ntxhua khaub ncaws hlau uas yog ib feem ntawm kev sib khi, lub tais me me lossis yas tuaj yeem ua rau muaj kev ntxhov siab. Kuv tau siv optical flats thiab xiav dye los xyuas qhov no. Koj yuav xav tsis thoob tias muaj pes tsawg lub tshuab ntxhua khaub ncaws los ntawm cov khw muag khoom siv pob zeb rau ntawm lub phaj. Qhov no tsis yog pickiness; 0.05mm warp tshaj 150mm txoj kab uas hla lub tshuab ntxhua khaub ncaws tuaj yeem txo qhov kev sib khi zoo los ntawm 30% nyob rau hauv bolt load.
Tom qab ntawd muaj qhov teeb meem kos npe. Koj xav tau traceability. Tab sis stamping tus naj npawb cua sov ncaj qha mus rau lub tshuab ntxhua khaub ncaws tuaj yeem ua rau cov chaw ua haujlwm txias thiab muaj kev ntxhov siab. Laser npav yog zoo dua, tab sis nws yuav tsum tau ntiav. Kuv nyiam qhov me me, etched cheeb tsam lossis txawm tias ib lub cim xaim mus rau pawg. Kuv ib zaug tau txais ib pawg uas tus neeg muag khoom tau ntaus tus ID, ua txhaum txoj cai max khoom thickness rau stamping. Peb yuav tsum tsis lees paub ntau. Nws zoo li tsis tseem ceeb, tab sis hauv kev txheeb xyuas tsis ua haujlwm, lub cim kos yog qhov chaw tawg feem ntau pib. Cov ntsiab lus yog txhua yam.
Tus neeg muag khoom toj roob hauv pes thiab Pragmatic xaiv
Nrhiav qhov chaw ntseeg tau tsis yog hais txog Googling Incoloy washer tsum. Nws yog hais txog kev nrhiav tus khub uas nkag siab txog metallurgy thiab daim ntawv thov. Muaj ntau tus neeg xa khoom xa tuaj yuav sau lawv, tab sis lawv tsuas yog muag. Koj xav tau ib lub chaw tsim khoom lossis ib tus kws tshaj lij tshaj lij. Ib lub tuam txhab zoo li Qingdao Qiangsenyuan Technology (QSY), nrog nws cov keeb kwm ntev hauv casting thiab machining tshwj xeeb alloys, yog positioned txawv. Lawv tsis yog txiav qhov khoob xwb; lawv koom nrog los ntawm theem xaiv cov khoom. Kuv tau xa lawv cov lus piav qhia ib puag ncig kev pabcuam, thiab lawv cov engineers tau rov qab los nrog cov lus qhia ntawm qib thiab kev tsim khoom-qee zaum casting tshaj machining kom zoo dua corrosion kuj nyob rau hauv cov duab kawg.
Nqe ib txwm yog qhov tseem ceeb, tab sis nrog Incoloy, qhov kev xaiv pheej yig yog lub ntxiab. Tus nqi ntawm cov khoom siv raw yog siab, yog li yog tias qhov kev tsocai qis dua, lawv tab tom txiav cov ces kaum-tej zaum ntawm chemistry, kev kho cua sov, lossis kev tshuaj xyuas. Kuv tau kawm thov cov ntawv pov thawj zeb ua ntej, tsis yog daim ntawv pov thawj ntawm kev ua raws cai xwb. Kuv xav pom qhov tseeb tshuaj ntsuam xyuas thiab kev ntsuam xyuas cov neeg kho tshuab rau cov cua sov ntawm cov khoom kuv cov ntxhua khaub ncaws yuav ua los ntawm. Cov khw muaj koob npe zoo li QSY muab qhov no raws li tus qauv. Nws tsim kev ntseeg siab.
Rau cov qauv ntau thiab tsawg, qee zaum nws ua rau kev txiav txim siab yuav los ntawm tus kws tshaj lij stockist. Tab sis rau txhua yam kev cai - khib OD / ID, tshwj xeeb tuab, qhov yuav tsum tau chamfer profile, lossis xav tau kev kho cua sov tshwj xeeb xws li annealing nyob rau hauv hydrogen huab cua - koj mus ncaj qha mus rau lub chaw tsim khoom. Lub sij hawm txhuas yog ntev dua, tab sis kev tswj tau tiav. Qhov tseem ceeb yog kev npaj. Tsis txhob tos kom txog thaum kawg ntawm kev txiav txim Incoloy ntxhua khaub ncaws; cov khoom ib leeg tuaj yeem muaj 8 lub lis piam ua haujlwm ntawm lub zeb.
Xaus Kev xav: Lub tshuab ntxhua khaub ncaws ua ib qho khoom siv
Yog li ntawd, tom qab tag nrho cov no, dab tsi yog qhov takeaway? Ib Incoloy ntxhua khaub ncaws yeej tsis yog ib qho khoom lag luam. Nws yog ib qho tseem ceeb engineered tivthaiv ntawm ib tug loj system. Nws qhov kev ua tau zoo yog kev ua haujlwm ntawm qib alloy, cov txheej txheem tsim khoom, qhov zoo ntawm cov khoom siv raw, thiab qhov tseeb ntawm cov txheej txheem tiav. Kho nws raws li ib tug yooj yim spacer yog qhov uas tsis ua hauj lwm pib.
Kev lag luam tau zoo dua, tab sis maj mam. Ntau tus kws tshaj lij tam sim no qhia tsis yog cov khoom siv tab sis kuj yog cov qauv tsim khoom (piv txwv li, ASME SB564 rau forgings), cov kev xeem uas tsis yog kev puas tsuaj (xws li kev ntsuas cov kua dej), thiab kev kho tom qab tsim khoom. Qhov kev nthuav dav no cais cov khoom siv ua haujlwm los ntawm kev lav phib xaub.
Thaum kawg, kev vam meej yog los ntawm kev sib koom tes ntawm tus tsim engineers, metallurgist, thiab cov chaw tsim khoom muaj peev xwm. Nws yog hais txog kev sib qhia tag nrho zaj dab neeg ntawm kev ua haujlwm ib puag ncig thiab ua tib zoo saib xyuas cov ntsiab lus uas feem ntau kos duab tshem tawm. Thaum qhov ntawd tshwm sim, tus ntxhua khaub ncaws uas txo hwj chim ua nws txoj hauj lwm rau ntau xyoo lawm, tsis pom thiab tsis tau hais txog-uas yog qhov kev qhuas siab tshaj plaws uas nws tuaj yeem tau txais.
