1. Dab tsi yog qhov kev siv tseem ceeb ntawm Incoloy A286 coils hauv kev lag luam roj thiab roj?
Teb:
Incoloy A286 coils yog tsim los rau siab -kub thiab siab - siv zog. Cov kev siv tseem ceeb muaj xws li:
Valve stems, fasteners, thiab springs nyob rau hauv cov khoom siv roj thiab roj
Siab - cov kav dej thiab cov kav dej hauv cov refineries thiab petrochemical cov nroj tsuag
Turbine thiab compressor Cheebtsam raug tshav kub heev
Thaum tshav kub kub exchangers thiab cov hlab ntsha siab nyob rau hauv ib tug nruj chemical ib puag ncig
Aerospace thiab marine daim ntaub ntawv uas yuav tsum tau corrosion kuj nyob rau hauv thermal stress
2. Dab tsi ua rau Incoloy A286 zoo tshaj rau cov qauv stainless hlau rau cov roj thiab roj?
Teb:
Tshwj xeeb tsis kam rau oxidation thiab carburization ntawm qhov kub siab (txog ~ 700 degree)
Lub zog tensile siab thiab creep tsis kam rau ntev -lub sij hawm siab - kub kev pab cuam
Tiv thaiv kom muaj kev ntxhov siab corrosion tawg hauv cov tshuaj chloride- muaj ib puag ncig
Kev qaug zog zoo heev, zoo tagnrho rau cov springs, coils, thiab fasteners nyob rau hauv cyclic loading
Ua tau zoo dua li 304/316 stainless hlau nyob rau hauv ob qho tib si siab - kub thiab corrosive tej yam kev mob
3. Dab tsi yog cov khoom tseem ceeb ntawm Incoloy A286 coils?
Teb:
Tensile zog: 950-1100 MPa (kev daws teeb meem annealed)
Tawm zog: 550-750 MPa
Elongation: ~ 20-25%, muab ductility zoo rau kev sib sau
Zoo heev creep thiab qaug zog tiv thaiv rau cov khoom nyob rau hauv kev ntxhov siab tsis tu ncua
Tuav lub zog thiab corrosion kuj mus txog ~ 700 degree, ua rau nws haum rau siab -kub roj thiab roj ua haujlwm
4. Yuav ua li cas Incoloy A286 coils yuav tsum tau ua los yog fabricated?
Teb:
Kev Ua Haujlwm Txias: tuaj yeem tsim rau hauv cov springs, coils, lossis xaim nrog kev sib txuas kom zoo los kho cov ductility.
Kev kho cua sov: tshuaj annealing ntawm 980-1050 degree, ua raws li kev ua kom txias sai, tuaj yeem txhim kho lub zog.
Vuam: Yuav tsum tau nickel-raws li cov hlau; preheating feem ntau tsis xav tau vim muaj cov ntsiab lus carbon tsawg.
Machining: Siv cov cuab yeej carbide los yog cov nqi noj qeeb vim yog cov alloy siab hardness thiab lub zog.
5. Dab tsi yuav tsum tau xav txog thaum xaiv Incoloy A286 coils rau cov roj thiab roj?
Teb:
Kub raug: Haum rau cov ntawv thov txog li 700 degree; xaiv raws li kev ua haujlwm.
Corrosive ib puag ncig: Resistant oxidizing thiab me ntsis txo cov tshuaj lom neeg; txheeb xyuas kev sib raug zoo nrog cov txheej txheem tshwj xeeb.
Mechanical load: Siab tensile thiab yield zog ua rau nws zoo tagnrho rau fasteners, springs, thiab siab - bearing Cheebtsam.
Fabrication yuav tsum tau: Coil forming, dabtsi yog khoov, thiab caij nplooj ntoos hlav manufacturing tej zaum yuav xav tau kev daws annealing.
Tus nqi-kev ua tau zoo: Txawm hais tias tus nqi siab dua li cov qauv stainless hlau, A286 muab kev ua haujlwm ntev - lub sijhawm ua haujlwm nyob rau hauv siab - kev ntxhov siab, siab - qhov kub thiab txias, txo cov nqi kho thiab hloov cov nqi.
