1. Dab tsi yog cov qib ntawm inconel?
Inconel 600: High Nickel-chromium alloy resistant rau corrosion thiab oxidation, siv rau hauv tshav kub hloov thiab nuclear cov ntawv thov.
Inconel 601: Muaj cov ntsuas zoo tshaj plaws tiv thaiv kom kub (txog li 1,200℃/ 2,192℃f), zoo rau cua sov rau cov cua sov {}}
Inconel 625: Paub txog rau lub zog siab, corrosion tsis kam (tshwj xeeb rau chlorides thiab seawater), thiab weldability; siv nyob rau hauv aerospace thiab offshore kev lag luam .
Inconel 690: Muaj ~ 30% chromium, ua rau nws zoo heev rau kev cuam tshuam corrosion tawg nyob rau hauv nuclear pense thiab nitric acid ib puag ncig {}}
Inconel 718: Hnub nyoog-nyuaj alloy nrog tshwj xeeb lub zog txog 700℃/ 1,292℃f, dav hauv cov cav tshuab thiab tshuab aerospace.
Inconel x -750: Cov tshuaj tiv thaiv cua sov kom sov rau qhov siab kub lub zog, siv rau hauv cov roj av thiab cov dav hlau .
Inconel 725: Tsim rau huab corrosion tsis kam nyob rau hauv cov roj tob-hiav txwv / roj av, tshwj xeeb rau pitting thiab crevice corrosion.
2. Puas muaj cov hlau muaj zog tshaj?
Inconel tsis yog cov hlau uas muaj zog tshaj plaws ntawm chav sov: Cov ntaub ntawv zoo li lub zog, lub siab-muaj zog hlau, lossis titanium alloys yuav muaj siab dua chav-kub lub zog.
Inconel excels ntawm qhov kub: Nws lub npib tsib xas raws lisuperior lub zog thiab ruaj khov ntawm kev nce kub(e {{. g}}}}}}}} Cov qib, ua rau nws tseem ceeb nyob rau hauv Aerospace Turboines {}}
Lub zog yuav muaj kev sib txawv los ntawm qib: Inconel 625 thiab 718 muaj zog dua li 600 lossis 601 vim yog alloy cov ntsiab lus xws li molybdenum, thiab aluminium (rau hnub nyoog hardening).
3. puas tuaj yeem inconel xeb?
Technically, tsis muaj-inconel tsis "xeb": Tsuav yog hais txog cov hlau oxide corrosion, thiab incrogel yog feem ntau npib tsib xee-based (nrog me ntsis rau tsis muaj hlau nyob rau qee qeb).
Inconel tuaj yeem corrode hauv cov xwm txheej huab:
Oxidation: Thaum kub siab heev, nws tsim oxide txheej (e {{}}}}} g}, sulfur) tuaj yeem ua rau maj oxidation {}}
Kev ua cev tub: Hauv kev txhoj puab heev (e {{{0} g {} Txawm li cas los xij, qee cov kev daws teeb meem, lossis cov qib kev ntxhov siab yog tsim los tawm tsam cov qauv no zoo dua li cov hlau tsis muaj zog lossis lwm yam alloys .
Qhov tseem ceeb: . Piv txwv, inconom 625 tawm ntawm cov tshuaj lom SCC, thaum Inconle Reactor Dej {}}
4.Puas muaj kev sib tw tau welded?
Vuam cov nyom:
Siab high thermal conductivity thiab tsawg thermal expansion tuaj yeem ua rau muaj kev ntxhov siab thiab tawg yog tias kub tsis tswj .
Qee qib (e {. g {}}}}}}
Kev paug los ntawm cov ntaub ntawv txawv teb chaws (e {{.}}}}, leej faj) yuav tsum zam, raws li lawv tuaj yeem txwv cov khoom.
Vuam Txoj Kev:
Roj Tungsten Arc Vuam (GTaw / TIG)yog ib txwm muaj rau nws qhov tseeb thiab cov kev pheej hmoo tsis huv .
Roj Hlau Hlau Arc Vuam (Gmaw / Mig)thiab Electron nqaj vuam kuj siv rau cov ntu thicker .
Cov Khoom Siv Tub Ua Kob: Sib piv cov tub lim hlau (e {. g}}, inconel 625) yog qhov tseem ceeb hauv weld .
Kev Kho Mob Tom Qab Weld: Qee cov ntawv thov yuav xav tau kev kho cua sov (e {{{}}}}}}}}}}}}}}}}}}}}}}
5. Dab tsi yog li tshwj xeeb txog inconel?
ResistS acids (e {. g}}}}}}
Chromium, molybdenum, thiab niobium nyob rau hauv alloy daim ntawv ruaj khov oxide txheej uas tiv thaiv tawm tsam Apladation .
Tswj lub zog, ductility, thiab cov plhuav tawm ntawm qhov kub thiab txias tsis (e {{}, txog li 1,100℃rau inconel 601).
Siv nyob rau hauv lub dav hlau xyaw, Roj turbines, thiab muaj chaw ua kom sov sov .
Ib tug tub rog: Turbine li pwm, tso tej tshuab .
Ua qhov hauv plawv: Reactor Cheebtsam (vim tias ntsuas hluav taws xob tsis kam lees) .
Offshore / Roj & Roj: Cov khoom siv seaterwater, tob-pipelines.
Kev Lag Luam: Reactors, kev hloov cua sov rau cov kua tshuaj ua kom huv si .
Cov qib kawm sib txawv hauv kev sib sau ua ke los daws cov kev xav tau tshwj xeeb (e {} g}, Oxidation tsis kam nyob rau hauv 625).
Tuaj yeem forged, dov, lossis ua kom sov kom ua tiav cov khoom siv xav tau.
Inconel 690 yog siv nyob rau hauv cov kev pheej hmoo nuclear vim nws cov ruaj khov nyob rau hauv hluav taws xob thiab dej corrosion .
