1. Dab tsi yog qhov tseem ceeb ntawm "ci" ua tiav thiab cov ATM B166 specification rau uns unic tsis zoo?
Kev sib xyaw ntawm ASTM B166 cov lus qhia tshwj xeeb thiab "ci" tiav yog qhov tseem ceeb yog qhov tseem ceeb rau kev lag luam precision rau kev lag luam. ASTM B166 is the standard specification for nickel-chromium-iron alloy (UNS N06600 and N06690) rods, bars, and wires. Nws ua kom nruj rau cov tshuaj muaj tshuaj, tshuab hluav taws xob, kom muaj zog, elongation lub zog, thiab suab loj, kev ywj pheej los ntawm kev tsis txaus ntseeg).
Qhov "ci ci" ua tiav, feem ntau ua tiav los ntawm kev sib tsoo raug mob, lossis polishing, qhia txog kev ua kom du, ntsuas} pub dawb, thiab ua kom meej dimensalal nto. Qhov no muaj cov txiaj ntsig tseem ceeb:
Txo cov machining: cov khoom tau los ze zog rau zaum kawg rau kev ua siab ntev, txo tus nqi ntawm kev xa khoom siv tom qab ntawd, uas txuag lub sijhawm thiab tus nqi.
Zoo dua cov chaw ua tiav zoo tshaj plaws muab qhov pib zoo tshaj plaws rau kev polishing ntxiv rau kev polishing ntxiv lossis feem ntau haum rau kev siv tas mus li. Nws txo txoj kev pheej hmoo ntawm cov kev tsis taus saum npoo deg ua cov ntsiab lus rau kev nkees lossis xeb.
Kev ua kom haum corrosion: huv si, huv si txhawb kev tsim cov txheej txheem loj dua thiab tiv thaiv cov roj chromium ntau dua, ua kom zoo nkauj rau alerent corrosion tsis kam.
Qhov no ua rau ci -}} ua tiav cov kev xaiv uas nyiam dua rau cov khoom lag luam nuclear, thiab semiconductor qhov twg yog qhov tsis yog {sib ceg.
2. Tus txheej txheem kev ntsuas khaub thuas siv los tsim cov teeb pom kev zoo dua rau cov khoom siv tshuab ntawm inconel 690 rau cov ntawv thov tshwj xeeb?
Txias duab kos yog qhov tseem ceeb thermomechanical txheej txheem uas rub tawm (kos duab) los ntawm kev tuag ntawm chav tsev kub kom txo nws tus ntoo khaub lig}}} seem thiab ua tiav qhov chaw du. Cov txheej txheem no tau txhim kho cov khoom siv tshuab ntawm inconel 690 los ntawm kev sib zog ua kom tawv tawv lossis ua haujlwm hnyav.
Raws li cov ntaub ntawv yog plastically deformed ntawm qhov tsis tshua muaj kub, nws txoj kev rho tawm ntom nce ntxiv, tsim kom muaj kev cuam tshuam nrog kev tshem tawm ntxiv. Qhov no ua rau:
Nce tensile thiab tawm lub zog: cov khoom siv zog zuj zus thiab nyuaj.
Txhim kho saum npoo hardness thiab hnav tsis kam: cov sab nraud ua nyuaj, muaj txiaj ntsig rau cov khoom siv rau kev ua kom puas tsuaj lossis galling.
Tswj kev txhim kho corrosion: Thaum lub sij hawm ua kom muaj zog ntxiv, tom ntej kev kho kom sov tuaj yeem siv tau los kho lub tshuab ua kom sov thiab kho kom haum yog tias xav tau rau kev sib txuas ntxiv.
Yog li ntawd, rau cov ntawv thov zoo li siab - Lub zog siv hluav taws xob, thiab cov khoom siv ua haujlwm siab dua ntawm cov khoom siv hluav taws xob, thiab cov khaub thuas siab dua}
3. Hauv kev lag luam semiconduct, yog vim li cas thiaj astm b166 ist n06690 ci ntsa iab bars tau teev rau cov khoom sib xyaw ua ke hauv Wafer Fabrication khoom?
Lub semiconductor tsim cov txheej txheem yog tshwj tsis muaj tshwj xeeb rau kev paug thiab yuav tsum tau cov ntaub ntawv ntawm cov kev coj dawb huv thiab kev ntseeg tau. ASTM B166 tsis yog N06690 cov kab tshuam ci ntsa iab tau teev rau ntau yam:
Ultra -} Purity High: Qhov txheej txheem ci teeb duab ua cov khoom siv huv si nrog cov nplai me me lossis cov lus me me. Qhov no yog qhov tseem ceeb raws li kev sib txuas ua paug tuaj yeem rhuav tshem tag nrho cov pob khoom ntawm cov khoom kim tshaj Silicon Wafers.
Ua kom tsis kam rau ntshav fabrication devents: Weching Fabrication zoo li cov tshuaj volosive plhuav (CRD) thiab etching siv Halogen Gases (piv txwv li, fluorine, chlorine, chlorine, chlorine, chlorine). Inconel 690 lub siab nibel - cov ntsiab lus chromium thiab corrosion ntawm cov neeg muaj sia nyob ntev, ua kom lub neej ntev ntev thiab cov txheej txheem ruaj khov.
Kev kom huv: tus du, tsis {{0} pailing ci ntawm cov tshuaj lom neeg yog yooj yim los ua kom huv si thiab tiv thaiv qhov tseem ceeb rau kev tswj cov dej huv.
Cov cheebtsam sib xws suav nrog cov ntshav thiab cov ntaub thaiv cov tshuab hluav taws xob, cov hluav taws xob faib tawm, cov hluav taws xob roj, thiab ntau yam ntxiv hauv cov chav ua.
4. Dab tsi yog qhov kev txiav txim siab thawj zaug rau kev kho cua sov tom qab kev sib xyaw ua ke los ntawm ASTM B166 ci ci?
Tshaj tawm - tshuab kev kho cua sov yog feem ntau qhov tseem ceeb kom ntseeg tau tias qhov kawg ua tau raws li nws cov kev pabcuam. Cov kev txiav txim siab thawj yog:
Lub Hom Phiaj: Lub hom phiaj tseem ceeb yog feem ntau tov anegealing. Qhov no cuam tshuam nrog kub ntau yam ntawm 1600 {}}}}}}} 18}℃f (870-10 10 Cov txheej txheem no tau ploj mus txhua yam carbide pharbide uas tej zaum yuav tau precipitated ib qho kev cuam tshuam ua ntej ntawm kev ua haujlwm hauv Welds
Kev ntxhov siab kev ntxhov siab: Rau cov khoom siv uas tau dhau los ntawm machining kev ntxhov siab (piv txwv li ntawm cov khoom siv hluav taws xob sab hauv tsis muaj kev cuam tshuam dab tsi, yog li kev txhim kho qhov ruaj khov.
Cov kev txiav txim siab nto: Qhov tseem ceeb ntawm kev pib nrog lub bar ci ci yog qhov chaw huv. Nws yog qhov tseem ceeb uas cov txheej txheem kho cua sov tsis qhia cov nplai lossis oxidation. Kev kho tshav kub hauv lub tshuab nqus tsev lossis cov huab cua - tswj cov roj ua kom ruaj khov (nrog cov roj ntsha ua kom ruaj khov thiab ua kom tiv thaiv cov roj oxide uas yuav xav tau cov pickling lossis xov tom ntej.
5. Rau cov ntaub pua chaw nuclear, vim li cas thiaj li muaj peev xwm ua tiav thiab cov khoom siv traceability ntawm Astm B166 Bright raug tswj hwm?
Lub nuclear kev lag luam ua haujlwm nyob rau hauv feem ntau cov cai tswj hwm zoo muaj kev ruaj ntseg qauv, xws li Asme BPVC Ntu III. Cov kev sib tw nruj rau ovm B166 Bright Brars yog vim muaj kev nyab xeeb- tseem ceeb ntawm cov khoom siv.
Tag nrho traceazeobility: txhua qhov bar yuav tsum tau tig rov qab mus rau nws tus lej melt Qhov no yog sau rau ntawm thaj chaw xeem zeb (MTC) uas qhia txog kev txheeb xyuas tshuaj lom neeg tiag tiag thiab cov tshuab hluav taws xob tshwj xeeb. Qhov no tso cai rau cov ntaub ntawv uas muaj peev xwm - qhov teeb meem ntsig txog yuav tsum tau taug qab thiab muaj.
Cov ntaub ntawv pov thawj ntawm cov khoom: Cov khoom yuav tsum tsis tau tsuas yog ua tau raws li ASTM B166 tab sis feem ntau ntau kev txwv nuclear- qib specifications. Qhov no ua rau kev sim ntxiv no ntxiv, suav nrog:
Kev txheeb xyuas tus kheej (PMI) los xyuas cov tshuaj chemistry.
Advanced tsis - Kev sim tshuaj (ndt) zoo li ultrasonic kuaj kom ntseeg tau lub suab sab hauv.
Grain loj pov thawj thiab corrosion kev sim (piv txwv li, astm g28) kom paub meej tias yuav muaj kev tawm tsam.
Cov theem ua kom zoo ntawm cov ntaub ntawv thiab cov ntaub ntawv pov thawj tau txais kev lees paub tias cov ntaub ntawv ntseeg tau txoj kev ntseeg siab ntawm cov pa hluav taws xob, kub thiab siab.
