Q1: Dab tsi yog qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg ntawm Inconel X750 thiab Inconel 600 seamless kav?
A1: Ob leeg Inconel X750 thiab Inconel 600 yog npib tsib xee-chromium raws li superalloys, tab sis lawv cov tshuaj muaj pes tsawg leeg sib txawv hauv cov ntsiab lus alloying. Inconel 600 muaj cov ntsiab lus yooj yim, feem ntau suav nrog 72% npib tsib xee, 14-17% chromium, 6-10% hlau, thiab cov lej ntawm manganese, silicon, thiab tooj liab, vam khom rau kev daws teeb meem ntxiv dag zog rau nws cov khoom. Hauv qhov sib piv, Inconel X750 (UNS N07750) muaj 70% npib tsib xee yam tsawg kawg nkaus, 14-17% chromium, 5-9% hlau, ntxiv rau 0.4-1.0% txhuas, 2.25-2.75% titanium, thiab 0.7-1.2% niobium (columbium). Cov ntsiab lus ntxiv no (aluminium, titanium, niobium) pab kom Inconel X750 kom ua tiav cov nag lossis daus hardening, txhim kho nws qhov kub thiab txias zog thiab nkag siab.
Q2: Dab tsi yog qhov sib txawv ntawm cov cuab yeej cuab tam tseem ceeb ntawm Inconel X750 thiab Inconel 600 seamless kav?
A2: Cov khoom siv kho tshuab ntawm ob lub alloys sib txawv heev vim lawv cov kev sib txawv zog. Inconel X750, raws li nag lossis daus -hardened alloy, muaj zog dua: nws lub zog tawm los ntawm 620 txog 830 MPa, lub zog tensile ntawm 950 txog 1350 MPa, thiab elongation ntawm 15 mus rau 25%, nrog kev ua haujlwm kub txog 980℃F (1800℃F). Inconel 600, ib qho khoom ua tau zoo{14}} kev daws teeb meem alloy, muaj lub zog qis dua tab sis zoo dua ductility: nws lub zog tawm los yog 240-450 MPa, tensile lub zog 550-690 MPa, elongation 40-55%, thiab nws tuaj yeem tiv taus kev ua haujlwm siab dua mus txog 1093℃(2000℃F). Nyob rau hauv cov ntsiab lus, Inconel X750 ua tau zoo nyob rau hauv siab zog thiab creep kuj, thaum Inconel 600 yog superior nyob rau hauv ductility thiab toughness.
Q3: Dab tsi yog cov ntawv thov ntawm Inconel X750 thiab Inconel 600 seamless kav?
A3: Lawv daim ntawv thov yog txawv raws li lawv cov kev ua tau zoo. Inconel X750 seamless kav, nrog zoo heev - kub lub zog, creep tsis kam, thiab corrosion kuj, yog dav siv nyob rau hauv aerospace (turbine cav Cheebtsam, foob pob ua ntxaij lub cev muaj zog), nuclear fais fab (steam generator tubing, reactor tswj rods), roj & roj (downhole Cheebtsam nyob rau hauv high-kub{5} qhov kub thiab txias). Inconel 600 seamless kav, paub txog zoo oxidation thiab corrosion kuj thiab superior ductility, feem ntau yog siv nyob rau hauv tshuaj ua (corrosive nruab nrab pipelines), nuclear fais fab nroj tsuag (piv txwv li structural Cheebtsam), industrial furnaces ( cua sov ntsiab), thiab marine propulsion systems raug dej hiav txwv.
Q4: Cov qauv kev lag luam twg siv rau Inconel X750 thiab Inconel 600 seamless kav?
A4: Ob lub alloys ua raws li cov qauv kev lag luam thoob ntiaj teb los xyuas kom meej cov khoom zoo. Inconel 600 seamless kav feem ntau yog them los ntawm ASME SB167 (tus qauv rau nickel-chromium- hlau alloy seamless kav thiab raj) thiab ASTM B167, uas qhia lawv cov kev tsim khoom, kev sim, thiab kev ua haujlwm. Inconel X750 seamless kav ua raws li cov qauv xws li ASTM B829, ASME SB829, thiab SAE AMS 5582, thiab feem ntau suav nrog hauv siab - kub thiab corrosion- tiv taus nickel alloy specifications raws li ASTM B167. Tsis tas li ntawd, ob qho tib si tuaj yeem tsim tau raws li ASME B36.10 / B36.19 rau qhov tshwj xeeb qhov ntev, thiab txhua pawg feem ntau yog nrog los ntawm MTC (Cov Khoom Siv Xeem Ntawv Pov Thawj) ua raws li EN 10204/3.1.
Q5: Dab tsi yog cov txheej txheem tsim khoom thiab kev tswj xyuas qhov tseem ceeb rau Inconel X750 thiab 600 seamless kav?
A5: Cov txheej txheem tsim khoom rau ob lub kav dej seamless zoo ib yam: nws pib nrog cua sov ib puag ncig cov khoom siv, uas yog tom qab ntawd pierced los ua lub plhaub hollow ntawm extrusion, ua raws li cov duab txias kom ua tiav qhov ntev, thiab thaum kawg kev kho cua sov kom zoo zog. Rau kev tswj kom zoo, cov kev ntsuas tseem ceeb suav nrog: 1) Kev kuaj tshuaj muaj pes tsawg leeg (xws li, spectral tsom xam) kom ua tau raws li cov qauv hlau alloy; 2) Kev ntsuas cov cuab yeej cuab tam (tensile, yield, elongation) tom qab kev kho cua sov; 3) Tsis yog-kev kuaj kev puas tsuaj, xws li kev ntsuas hydrostatic siab (los kuaj xyuas qhov siab-cov kabmob muaj peev xwm thiab cov xau nruj) thiab kev ntsuas tam sim no eddy (kom pom qhov chaw thiab nyob ze - qhov chaw tsis xws luag); 4) Kev tswj xyuas nruj ntawm kev kho cua sov (xws li, lub tshuab nqus tsev laus rau Inconel X750, ruaj khov- kev daws teeb meem rau Inconel 600) kom ntseeg tau tias kev ua haujlwm zoo ib yam ntawm cov khoom siv.
