Aerospace: Inconel 690 yog ua hauj lwm nyob rau hauv siab - ib puag ncig kev nyuaj siab nyob rau hauv aerospace daim ntaub ntawv, xws li cav Cheebtsam thiab tso pa system ua hauj lwm nyob rau hauv lub kub huab cua.
3. Inconel 690 piv rau lwm cov nickel alloys zoo li Inconel 625 lossis Inconel 718 li cas?
Teb:
Inconel 690 muaj qee qhov zoo thiab qhov sib txawv thaum piv rau lwm cov nickel-raws li alloys:
Inconel 625: Txawm hais tias ob qho tib si alloys muaj kev tiv thaiv corrosion zoo heev, Inconel 625 excels hauv kev tiv thaiv cov tshuaj phem xws li dej hiav txwv thiab feem ntau siv nyob rau hauv marine ib puag ncig. Inconel 690, ntawm qhov tod tes, yog tsim los kom zoo dua siab dua -kub oxidation tsis kam thiab siv ntau dua hauv daim ntawv thov nuclear thiab roj turbine.
Inconel 718: Inconel 718 feem ntau yog siv rau kev siv aerospace thiab roj turbine vim nws lub zog tshwj xeeb ntawm ob qho tib si cryogenic thiab kub. Txawm li cas los xij, nws tsis tshua muaj kev cuam tshuam rau kev ntxhov siab corrosion tawg nyob rau hauv ib puag ncig corrosive heev piv rau Inconel 690, uas yog tsim tshwj xeeb los tiv thaiv siab - kub corrosion thiab tawg nyob rau hauv ib puag ncig xws li nuclear reactors thiab tshuaj ua.
4. Dab tsi yog qhov kev siv tseem ceeb ntawm Inconel 690 seamless kav hauv kev lag luam hluav taws xob nuclear?
Teb:
Inconel 690 seamless kav yog dav siv nyob rau hauv lub nuclear fais fab kev lag luam vim lawv zoo heev tiv thaiv corrosion thiab kev nyuaj siab tawg, ua rau lawv zoo tagnrho rau ntev - lub sij hawm raug mob hnyav.
Steam generator tubing: Inconel 690 yog siv rau hauv cov tshuab hluav taws xob nuclear, qhov uas nws yuav tsum tiv taus siab -siab chav thiab dej kub thaum tswj kev ncaj ncees nyob rau lub sijhawm.
Reactor core Cheebtsam: Inconel 690 lub peev xwm los tiv thaiv hluav taws xob thiab kub kub ua rau nws zoo tagnrho rau cov roj cladding thiab lwm yam tseem ceeb cov khoom raug rau huab cua nyob rau hauv lub reactor.
Cov kav dej: Cov hlau yog siv rau cov kav dej uas thauj cov dej txias thiab lwm yam dej hauv cov chaw tsim hluav taws xob nuclear, qhov uas yuav tsum muaj kev tiv thaiv corrosion thiab hluav taws xob puas.
5. Dab tsi yog qhov nyuaj hauv kev tsim cov kav dej Inconel 690 seamless?
Teb:
Thaum Inconel 690 muaj kev ua tau zoo heev, nws kuj nthuav tawm cov kev sib tw hauv kev tsim, suav nrog:
Kev ua haujlwm nyuaj: Vim nws lub zog siab thiab hardness, Inconel 690 tuaj yeem nyuaj rau tshuab. Cov cuab yeej tshwj xeeb thiab cov txheej txheem feem ntau yuav tsum tau ua, thiab kev ua haujlwm ceev yuav tsum tau hloov kho kom tsis txhob hnav cov cuab yeej ntau dhau.
Vuam nyuaj: Txawm hais tias Inconel 690 yog weldable, nws yuav tsum muaj kev tswj xyuas cov cua sov kom tsis txhob muaj teeb meem xws li thermal tawg lossis distortion. Lub alloy feem ntau yuav tsum tau ua ntej- cua sov thiab tom qab-weld kev kho cua sov kom ntseeg tau tias kev ua haujlwm zoo.
Tus nqi: Raws li cov khoom siv ua haujlwm siab, Inconel 690 nyiam kim dua li lwm cov alloys, xws li carbon steel lossis stainless hlau, uas tuaj yeem nce nqi tag nrho ntawm cov khoom tsim los ntawm cov khoom siv no.
Kev kho cua sov: Inconel 690 yuav tsum tau ua cov txheej txheem kho cua sov tshwj xeeb kom ua tiav cov khoom xav tau thiab kev tiv thaiv corrosion, uas tuaj yeem yog lub sijhawm- siv thiab xav tau cov cuab yeej tshwj xeeb.
