Kub-kub corrosion kuj tsis yog xaiv tau - nws yog lub hauv paus. Thaum tso pa tawm manifolds ci cherry liab, thaum turbine vaj huam sib luag nyob nruab nrab ntawm 700 ° C thiab ceev cooldown, los yog thaum acid-laden txheej txheem kwj noj los ntawm tus qauv stainless ntawm 0.1 hli / xyoo, tsuas yog ib chav kawm ntawm cov ntaub ntawv tuav txoj kab: nickel-chromium superalloys zoo li Inconel. Tab sis raw khoom qib ib leeg tsis lav kev ua haujlwm. Kev ntseeg tiag tiag nyob ntawm seb yuav ua li cas Inconel ib feem yog tsim-tsis yog qhov nws tau ua los ntawm.
Peb tau pom ntau qhov project tsis yog vim kev xaiv alloy, tab sis vim yog kev tswj tsis tau. Ib tus neeg siv khoom hauv North Hiav Txwv cov roj & roj tau teev tseg Inconel 625 rau lub siab tswj lub valve tsev nyob - tom qab ntawd tau txais cov khoom nrog cov nplej tsis sib haum, micro-porosity ze rau thaj chaw muaj kev kub ntxhov, thiab tawg ntxov ntxov tom qab 4,200 lub voj voog thermal. Hauv paus ua rau? Tus neeg muag khoom siv CNC machining generic rau li-cam khwb cia blanks tsis muaj kev ntxhov siab-relief annealing lossis directional solidification tswj. Inconel tiv thaiv oxidation - tab sis tsuas yog yog tias nws cov qauv dendritic tseem tsis sib xws, nws cov carbide faib zoo thiab tawg, thiab nws cov kev ntxhov siab nyob hauv qab 120 MPa.
Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., txhua Inconel ib feem pib nrog AMS-certified billet los yog peev-cam khwb cia preform-tsis txhob seem-re-melted Tshuag. Peb tshawb xyuas chemistry ntawm OES ua ntej machining, taug qab txhua qhov ntau los ntawm lub cub tawg mus rau qhov kawg CMM daim ntawv tshaj tawm, thiab siv cov tshuaj annealing ntawm 1,095 ° C ± 5 ° C nrog tswj argon quenching. Qhov ntawd yog li cas peb tuav cov qoob loo loj rau ASTM E112 Qib 5-6 hla cov geometries nyuaj xws li piston twj tso kua mis lub tog raj kheej vaj tse - qhov chaw uas pom 350 bar pulsation thiab 650 ° C tso tawm rov qab.
Inconel 718 txiav ntawm 1/3 tus nqi pub ntawm 316 stainless. Cov cuab yeej lub neej poob 70% nrog txhua 50 ° C nce siab tshaj 600 ° C workpiece kub. Qee lub khw teb los ntawm kev ua kom qeeb txhua yam - tom qab ntawd xav paub yog vim li cas cov sij hawm coj mus rau 14 lub lis piam thiab qhov roughness hits Ra 3.2 µm es tsis yog qhov yuav tsum tau Ra 0.8.
Peb ua peb yam sib txawv:
Qhov no tsis yog txoj kev xav. Nws yog li cas peb tau xa 217 AMS 5387 cobalt-alloy 6 twj tso kua mis rau German hydraulic OEM-nrog GD&T Zone ua raws cai tuav rau ± 0.015 hli ntawm 12 qhov tseem ceeb datums, xoom rework, thiab tag nrho traceability kom yaj tooj thiab kub-kho lub voj voog cav.
Qee tus engineers ua rau Inconel 600 rau qhov chaw muaj sulfur-nplua nuj. Nws ua haujlwm - rau rau lub hlis. Ces intergranular nres pib ntawm weld HAZs. Lwm tus qhia Inconel 625 rau cov kev pabcuam chloride-tsis quav ntsej nws qhov cuam tshuam rau crevice corrosion hauv qab pH 4.5 thiab 80 ° C.
Peb tsis tsuas yog phim cov alloys rau cov kab kos kub. Peb daim ntawv qhia lub hnab ntawv ua haujlwm tag nrho: qhov siab tshaj plaws, thermal ramp tus nqi, dej tshaj tawm, pH, chloride ppm, thiab mechanical loading profile. Rau cov twj tso kua mis tawm sab nraud, peb tau hloov cov neeg siv khoom los ntawm Inconel 625 mus rau Inconel 686 - ntxiv 3% tungsten thiab 1.6% niobium - txhawm rau txuas lub neej kev pabcuam ntawm 9 txog 34 lub hlis hauv 120 ° C, 15,000 ppm Cl⁻ brine. Rau high-wear winch center ncej chais rau engineering tsheb, peb siv T800-raws li cobalt-nickel overlays thov ntawm plasma hloov arc-ua tiav 62 HRC nto hardness nrog xoom delamination tom qab 2.1 lab torque cycles.
Kev xaiv cov ntaub ntawv tsis yog daim ntawv txheeb xyuas. Nws yog kev sib tham ntawm metallurgical-nrog koj ib puag ncig, koj qhov geometry, thiab koj hom tsis ua haujlwm.
Kev ntseeg tau pib ua ntej thawj nti ya. Peb tshuaj xyuas txhua qhov GD&T callout - tsis yog rau kev ua raws, tab sis rau kev tsim khoom. Ib txoj hauj lwm kam rau ntawm Ø0.02 hli ntawm 300 hli flange? Ua tau-tab sis tsuas yog nrog cov av datum nto thiab huab cua-kev coj tus kheej CMM pov thawj. Peb chij cov thaum ntxov. Peb kuj tseem sim drawability ntawm qhov sib sib zog nqus nqus Inconel 718 diaphragms siv cov duab correlation (DIC), kwv yees cov kab mob hauv cheeb tsam ua ntej cov cuab yeej raug txiav.
Peb lub tuam txhab ISO-raws li kev tswj hwm tag nrho cov saw: cov ntaub ntawv pov thawj raw khoom, peev casting rau intricate intricate passages, 5-axis CNC rau nruj-tolerance sab nraud nta, nqus cua sov kho, thiab nto finishing-xws li electropolishing rau tshuaj twj tso kua mis sib dhos thiab nyuaj-anodized coatings rau marine winch zog. Kev tshuaj xyuas zaum kawg suav nrog kev kuaj tshuaj zas xim rau ib qho ASTM E1417, ultrasonic scanning ib ASTM E1961, thiab kev ua haujlwm siab rau 1.5 × ua haujlwm siab.
Yog tias koj xav tau ib qho Inconel ib feem uas ciaj sia - tsis yog haum - hu rau QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ncaj qha. Peb teb cov lus nug engineering hauv 4 teev ua haujlwm. Peb muab cov ntaub ntawv pov thawj raw khoom ua ntej kev txiav txim pom zoo. Thiab peb xa cov ntawv qhia qhov ntev nrog txhua qhov khoom xa tuaj.
