1.Qhov twg: Dab tsi yog qhov tshwj xeeb kev kho cua sov yog inconel 600 nickel alloy kav (thiab vim li cas thiaj siv tau zoo tagnrho rau cov ntawv thov no?
Teb: Inconel 600 kav dej nyob rau hauv cov qauv no tau siv nyob rau hauv kev kho cua sov kev kho thiab lub tshuab raj, cub tawg, thiab cov annaling pob tawb. Lawv cov haum rau ntawm npib tsib xee (72%) thiab chromium (14-17%) cov ntsiab lus zoo tshaj plaws txog kev cai lij choj hauv kev ntseeg siab rau ib puag ncig.
2.Qhov nyiaj txiag yuav ua li cas Astime
Teb: ASTM B163 npog seamless npib tsib xee thiab nickel-alloy compressions, tsom mus rau qhov ntev, thiab corrosion tsis kam rau cov kua tuav. ASTM B517 qhia meej txog kev sib tw Nickel-alloy-alloy-alloy-alloy rau kev pab kub siab, hais txog creep tsis kam thiab thermal stability. Rau cov neeg siv kawg, B163 cov leeg yog qhov zoo dua rau cov tshuab hluav taws xob zoo dua, thaum lub sijhawm B517 tau nyiam dua rau cov cua sov kom ntev hauv kev kub.
3.Question: Cov khoom siv tshuab ntawm inconel 600 (N06600) cov raj kom lawv ruaj khov kho kev ua haujlwm ntawm cov cua sov rov qab?
Teb: Inconel 600 leeg nthuav qhia lub zog tensile ntawm 550-690 mpa kom muaj zog ntawm 240-310 MPa, thiab 30-40% elongation nyob rau hauv chav tsev kub. Thaum nce qhov kub thiab txias, lawv khaws lub zog nruab nrab thiab ductility, tiv taus creep thiab thermal nkees. Tshaj dhau mus ncig ua voj voog, lawv ruaj microstructure embrittlement, kom ua tau zoo ib yam kev ua tau zoo hauv cov chaw sov nrog cua sov / cua txias.
4.Question: Qhov kev pheej hmoo corrosion 600 leeg nyob rau hauv kev kho cua sov, thiab lawv txoj kev pheej hmoo li cas cov kev pheej hmoo no?
Teb: Kev phom sij suav nrog oxidation (los ntawm huab cua kub), carburization (los ntawm hydrocarbon-nplua nuj (los ntawm leej faj-muaj cov roj). Chromium nyob rau hauv Incmel 600 ua cov txheej txheem tiv thaiv oxidation, thaum cov ntsiab lus nickel, thaum cov ntsiab lus siab npib tsis kam lees kho carbon diffusion. Tsis tas li ntawd, qis sulfur thiab phosphorus impurities nyob rau hauv alloy (ib astm specs) txo qis kev ntxim siab kom embrittlement los ntawm sulfidation.
5.Questionion: Qhov kev ntsuas zoo li cas yog xav tau rau Inconel 600 leeg nyob rau Astm B163 / B517 kom ntseeg tau tias kev ntseeg tau hauv kev kho cua sov?
Teb: Yuav tsum muaj kev xeem suav nrog: Tshuaj Ntsuam Xyuas Kev Ntsuam Xyuas (los ntawm OES) kom paub txog tus menyuam yaus, chromium, thiab cov ntsiab lus hlau; hydrostatic siab ntsuas mus kuaj rau cov xau; Ultrasonic lossis EDDY Kev Soj ntsuam tam sim no rau saum npoo / subsurface qhov teeb meem; thiab tensile kuaj kom paub meej tias cov khoom siv neeg kho tshuab. Rau kev siv kub siab, yeem nkag mus tsis muaj kev sib tw yuav ua tau. Cov ntawv pov thawj suav nrog MRS (ib ASTM E413) thiab ua raws li Norsok lossis ISO 9001 rau kev ua kom haum rau cov cua sov ib puag ncig.
