2. Dab tsi yog qhov tseem ceeb ntawm Incoloy, Monel, npib tsib xee, thiab hastelloy alloys hauv ntau yam kev lag luam?
Teb:
Incoloy alloys: feem ntau yog siv nyob rau hauv cov ntawv thov uas yuav tsum muaj siab thiab ua rau muaj cov nroj tsuag hluav taws xob, cov tshuaj tua hluav taws xob, thiab cov tshuaj tiv thaiv cov tshuaj lom neeg.
Monel aleloys (piv txwv li, Monel 400): Zoo heev tsis kam rau dej hiav txwv thiab siab} {} {}}}}}}} {{ecshore roj rigs, thiab nroj tsuag tshuaj lom neeg.
Nickel alloys: Muab cov kev tiv thaiv zoo heev rau cua sov, ua kom zoo nkauj, ua kom zoo tshaj rau kev siv hauv Aerospace, tsheb, lub zog hluav taws xob, thiab petrochemical Industries.
Hasteloy alloys: paub rau lawv qhov tshwj xeeb tiv taus rau cov tshuaj hnyav thiab cov ntsuas kub. Lawv tau dav siv hauv kev ua tshuaj lom neeg, nuclear reactors, thiab lwm thaj chaw muaj kev txhim kho ib puag ncig.
3. Dab tsi yog cov neeg kho tshuab ntawm cov alloys (incolel, itoloy, Monel, npib tsib xee, hackel, hackel)?
Teb:
Inconel 725, 750, 800, 825: Cov alloys muaj ntau lub zog, thiab oxidation tiv taus ntawm qhov kub (txog li 1800℃f / 982 degree). Lawv zoo {- ruited rau high- muaj kev ntxhov siab, siab}}}}} kub ib puag ncig.
Incoloy alloys: cov no muaj lub zog zoo tensile, zoo heev rau cua sov kom cua sov, thiab tuaj yeem tiv thaiv siab}}℃f (704 degree).
Monel alelys: lawv muab lub zog siab thiab zoo heev corrosion tsis kam, tshwj xeeb hauv dej hiav txwv, ua rau lawv zoo tshaj rau cov kev siv marine. Tensile lub zog feem ntau yog li ntawm 55,000 rau 75,000 PSI.
Hasteloy alloys: paub txog lawv qhov tshwj xeeb tiv taus corrosion tawg thiab lawv cov cuab yeej siv tshuab, lawv ua tau zoo nyob rau hauv ob qho siab - kub thiab muaj cov mob corrosive. Lub zog tensile feem ntau yog li 80,000 psi.
4. Yuav ua li cas cov alloys ua tiav thiab tsim mus rau hauv cov ntawv txheeb thiab daim hlau?
Teb:
Cov alloys tau ua tiav los ntawm ntau theem:
Kub Rolling: Lub alloy yog rhuab rau ib qho kub tshwj xeeb kom nws yooj yim dua. Qhov no feem ntau ua tiav ntawm qhov kub siab tshaj 1000℃(1832 Qib F).
Colding txias: Tom qab kub dov, cov khoom yog txias thiab tom qab ntawd txuas ntxiv siv cov kev xav tau tuab, nto tiav, thiab muaj zog.
Annaling: Cov phiaj yog tom qab ntawd kub -}} nrhiav (anealed) los ua kom muaj kev ntxhov siab sab hauv thiab txhim kho cov khoom siv tshuab.
Cov tiav saum npoo: Qhov kawg ua tiav cov txheej txheem, suav nrog pickling, sib tsoo, lossis polishing, yog ua los xyuas kom meej surfaces thiab tshem tawm cov kab mob oxidation lossis cov dej paug.
5. Yuav tsum muaj pov thawj dab tsi rau cov ntaub ntawv no, thiab vim li cas lawv tseem ceeb?
Teb:
Alloy cov ntawv thiab cov phaj zoo li incolel, itoloy, Monel, npib tsib, thiab Hastelloy yuav tsum ua kom zoo thiab cov qauv khoom siv, xws li:
ASTM Cov Qauv (piv txwv li, Astm B168, ASTM B164, ASTM B164, ASTM B64): Cov qauv no qhia meej cov tshuaj lom neeg muaj pes tsawg leeg, cov txheej txheem kev sim ua haujlwm rau cov alloys.
ISO 9001: Xyuas kom meej tias kev tsim khoom tsim ua raws li cov qauv kev tswj hwm zoo.
NACE MR0175 / ISO 15156: Rau cov ntaub ntawv siv nyob rau hauv cov chaw muab kev pab cuam muaj peev xwm tiv taus corrosive thiab qaub cov kev thov hauv cov roj thiab roj app.
En 10204 3.1. B Cov Ntawv Pov Thawj: Yuav tsum muaj rau cov khoom tracability thiab kev paub zoo, cov khoom pov thawj rau kev sim, cov kws kho mob, thiab tsom xam tshuaj.
Cov ntawv pov thawj no ua kom cov ntaub ntawv ua haujlwm raws li tau xav tias nyob rau hauv kev thov ib puag ncig thiab ntsib cov qauv kev cai thiab kev nyab xeeb.
