Inconel siv qhov twg? Cov ntawv thov hauv Aerospace, Roj & Roj thiab Kev Lag Luam Hluav Taws Xob

Ntawm Jiangsu XuRui Hlau Group Co., Ltd., peb tau muab Inconel alloys rau cov neeg siv khoom thoob plaws aerospace, roj & roj, thiab tsim hluav taws xob rau ntau tshaj kaum xyoo. Thiab cov lus nug uas peb hnov ​​feem ntau tsis yog "Inconel yog dab tsi?" tab sis "Nws ua qhov txawv qhov twg- thiab nws puas tsim nyog rau kev nqis peev rau kuv daim ntawv thov?" Cov lus teb tsis pom nyob rau hauv daim ntawv qhia dav dav. Nws los ntawm kev pom tias Inconel ua li cas qhov twg lwm cov ntaub ntawv ua tsis tiav.

Lub caij nplooj zeeg dhau los, tus neeg siv khoom tsim cov khoom siv rau tom ntej - tiam turbofan lub cav xav tau cov khoom siv uas tuaj yeem tiv taus 750℃tso pa roj thaum tiv thaiv thermal qaug zog thiab oxidation. Lawv pib ntsuas qib siab stainless hlau thiab cobalt alloys. Tab sis tom qab tshuaj xyuas cov ntaub ntawv thermal cycling thiab cov kev xav tau nkag, peb pom zoo rau Inconel 718 rau turbine disks thiab Inconel 625 rau kev tso pa tawm. Tom qab cov qauv kev sim thiab ntawv pov thawj, cov khoom siv tau dhau 5,000-kev sim qaug zog nrog xoom tawg. Cov chemistry ua haujlwm-tsis yog vim nws "kim," tab sis vim nws tau sib tw rau qhov kev sib tw.

Hauv aerospace, Inconel tsis yog khoom kim heev- feem ntau nws tsuas yog cov khoom siv uas ua tau raws li qhov yuav tsum tau muaj ntawv pov thawj rau cov khoom tseem ceeb:

• Turbine engines: Disks, hniav, thiab casings nyob rau hauv kub qhov chaw uas kub tshaj 650℃thiab centrifugal loads yog heev. Inconel 718 cov nag lossis daus- muaj peev xwm ua kom tawv nqaij muab lub zog xav tau-rau- qhov hnyav piv.
• Cov pa hluav taws xob thiab lub zog thim rov qab: Inconel 625 tiv thaiv oxidation thiab thermal qaug zog nyob rau hauv cyclic siab - cua sov ib puag ncig. Ib tus neeg siv dav hlau hauv cheeb tsam tau ncua sijhawm txij nkawm los ntawm 30% tom qab hloov mus rau 625 rau cov khoom siv hluav taws xob.
• Fasteners thiab fittings: High-lub zog, corrosion{1}}cov khoom siv tiv taus uas yuav tsum ua kom ntseeg tau hla -55℃rau +500℃kub viav vias.

Cov xov zoo sib xws: kev siv aerospace xav tau cov ntaub ntawv uas tswj xyuas kev ncaj ncees nyob rau hauv kev sib xyaw thermal, mechanical, thiab ib puag ncig kev ntxhov siab. Inconel xa- tsis yog los ntawm kev thov kev lag luam, tab sis dhau kaum xyoo ntawm kev ya davhlau- pov thawj kev ua tau zoo.

Hauv roj & roj, Inconel daws cov teeb meem uas txheem alloys tsis tuaj yeem ua:

• Kev pabcuam roj qaub: Cov khoom siv raug rau H₂S, CO₂, thiab chlorides yuav tsum tau tiv thaiv sulfide kev nyuaj siab tawg thiab pitting. Inconel 625 cov ntsiab lus molybdenum (8-10%) muab kev tiv thaiv tseem ceeb. Ib tug offshore platform tus neeg siv tau txo lub valve hloov zaus los ntawm 18 lub hlis mus rau 7+ xyoo tom qab hloov kho mus rau 625 trim.
• Kev siv dej sib sib zog nqus thiab HPHT: Siab-siab, siab- qhov dej kub xav tau cov ntaub ntawv nrog kev nkag siab zoo heev thiab cov tshuaj chloride kev ntxhov siab corrosion tawg tiv thaiv. Inconel 718 feem ntau tau teev tseg rau downhole kev nyab xeeb li qub thiab tswj kab kho vajtse.
• Cov tshuab hluav taws xob thiab cov kav dej tso tawm: Cov khoom sib txuas ua rau muaj kev sib tshuam siab -kub combustion gases tau txais txiaj ntsig los ntawm Inconel's oxidation resistance thiab thermal fatigue kev ua tau zoo.

Ib qhov project LNG tsis ntev los no qhia txog tus nqi. Ib tus neeg siv khoom xav tau tubing rau cov khoom siv hluav taws xob cryogenic uas tuaj yeem tswj tau qee zaus acid gas thaum pib. Tom qab kuaj ntau yam alloys, Inconel 625 xa tsuas yog ua ke ntawm qis- kub toughness, chloride tsis kam, thiab fabricability uas ua tau raws li tag nrho cov yuav tsum tau.

Hauv kev siv hluav taws xob, Inconel txhawb nqa ob qho tib si ib txwm muaj thiab cov thev naus laus zis tshiab:

• Gas turbines: Combustor liners, hloov daim, thiab cov hniav txuas ua haujlwm ntawm 800℃+ xav tau oxidation kuj thiab creep zog. Inconel 617 thiab 740H tau nce ntxiv rau cov nroj tsuag ultra-supercritical siab.
• Pov tseg-rau- lub zog thiab biomass boilers: Cheebtsam raug rau corrosive flue gases (chlorides, sulfides, alkali hlau) tau txais txiaj ntsig los ntawm Inconel 625's multi-media resistance. Ib tsob nroj hauv nroog tau txuas ntxiv lub neej ntawm superheater raj ntawm 3 mus rau 9 xyoo tom qab hloov mus rau 625 cladding.
• Nuclear daim ntaub ntawv: Inconel 600 thiab 690 muab kev txhim khu kev qha nyob rau hauv reactor coolant systems uas hluav taws xob, kub, thiab dej chemistry tsim tshwj xeeb degradation mechanisms.

Thaum cov neeg siv nug txog Inconel daim ntawv thov, peb tsis pib nrog cov lej. Peb pab lawv:

• Txhais cov kev pabcuam tiag tiag: qhov kub thiab txias profile, xov xwm muaj pes tsawg leeg, lub xeev kev ntxhov siab, lub neej xav tau
• Tshawb xyuas cov qauv tsis ua haujlwm ntawm cov ntaub ntawv tam sim no txhawm rau txheeb xyuas qhov twg Inconel ntxiv tus nqi
• Muab cov ntawv pov thawj zeb kuaj cov ntaub ntawv nrog cov ntaub ntawv tiag tiag thiab cov ntaub ntawv siv tshuab
• Txhawb kev xaiv cov ntaub ntawv nrog daim ntawv thov - cov ntaub ntawv tshawb fawb tshwj xeeb thiab cov ntaub ntawv xeem

Inconel tsis siv nyob txhua qhov chaw-tab sis qhov twg qhov kub thiab txias, corrosion, lossis kev ntxhov siab ntawm kev sib tshuam, nws feem ntau dhau los ua cov khoom xaiv. Aerospace cia siab rau nws rau kev ya davhlau- cov khoom tseem ceeb. Roj & roj nyob ntawm nws rau kev pabcuam qaub kev ntseeg tau. Lub zog tsim hluav taws xob ua rau nws ua kom huv, ua kom muaj zog ntau dua.
