Thaum engineers qhia Kev 800 rau high-temperature, high-corrosion daim ntaub ntawv-xws li cov chav hloov pauv cov raj, cov cua kub exchanger plhaub, los yog hydrocarbon ua manifolds-lawv tsis yog xaiv ib tug alloy. Lawv betting rau metallurgical sib xws, seem fidelity nyob rau hauv thermal cycling, thiab xoom kam rau ua microstructural segregation. Tias yog vim li cas muab los ntawm qhov tseeb Incoloy800 Hoobkas Qhov teeb meem - tsis yog tus neeg sawv cev ua lag luam, tsis yog lub hom phiaj dav dav, tab sis ib qho chaw nrog cov ntaub ntawv txheej txheem tswj kev daws teeb meem, kev ruaj ntseg ntawm cov nplej, thiab cov khoom kub ua haujlwm tshwj xeeb rau Fe-Ni-Cr superalloys.
Peb tau pom ntau qhov chaw nres tsheb vim tias tus neeg muag khoom tau hais txog Incoloy800 - tab sis xa cov khoom nrog 0.02% sulfur ntau dhau, ua rau muaj kev sib tsoo thaum lub sij hawm weld overlay. Los yog phem dua: qhov chaw machined los ntawm billet nrog cov keeb kwm tsis muaj kev kub ntxhov, ua rau ntxov ntxov creep rupture nyob rau hauv 750 ° C kev pab cuam. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., txhua qhov kev txiav txim Incoloy800 pib nrog cov ntawv xov xwm mill-test pov thawj tawm tsam ASTM B407 thiab ASME SB-407. Peb tsuas yog los ntawm cov mills tau ntawv pov thawj rau NADCAP AC7108 rau kev ua cov nickel-alloy-thiab peb khaws tag nrho traceability: ntau tus naj npawb, yaj ID, thermomechanical kho log, thiab tom qab anneal hardness pov thawj. Tsis muaj kev zam.
Dab tsi cais tus muaj peev xwm Incoloy800 Hoobkas los ntawm tus neeg muag khoom tsis yog ntawv pov thawj nkaus xwb - nws yog li cas cov alloy coj * tom qab * fabrication. Incoloy800 ua hauj lwm-hardens sai heev. Nws thermal conductivity yog tsawg. Nws lub zog kub xav tau cov tswv yim zoo ntawm cov cuab yeej cuab tam thiab tswj cov khoom xa khoom txias. Peb khiav tag nrho Incoloy800 CNC cov kev pab cuam ntawm 5-axis tshuab nrog lub sijhawm tiag tiag spindle load xyuas. Pub cov nqi kho dynamically raws li saum npoo hardness mapping-vim ib batch tuaj yeem sib txawv ± 15 HB hla nws hla ntu. Peb tsis yog tshuab luam ntawv xwb; peb tshuab rau * ua haujlwm *. Lub twj tso kua mis lub tsev tsis yog ib puag ncig-nws yuav tsum muaj kev sib koom ua ke ntawm ≤0.015 hli ntawm kev ua haujlwm kub, yog li lub piston foob tsis chatter. Qhov ntawd yuav tsum tau txo kev ntxhov siab * ua ntej * zaum kawg machining, tsis yog tom qab.
- Dimensional stability nyob rau hauv thermal load: Tag nrho Incoloy800 Cheebtsam tau txais ob-txoj kev ntxhov siab - ua ntej ntawm 900 ° C rau 2 teev nyob rau hauv lub cub tawg nitrogen, tom qab ntawd ntawm 760 ° C rau 4 teev nrog txias txias (≤20 ° C / teev)
- Deg kev ncaj ncees rau corrosion kuj: Tsis sib tsoo hlawv. Tsis muaj microcracks subsurface. Txhua qhov dhau los ntawm kev tshuaj xyuas fluorescent penetrant (ASTM E1417) thiab kev txheeb xyuas qhov roughness (Ra ≤ 0.8 µm ntawm lub ntsej muag sealing)
- Weld npaj: Tag nrho cov khoom nyoos yog tov-annealed thiab pickled rau ASTM A959, nrog cov ntsiab lus ferrite tau lees paub hauv qab 0.5% - qhov tseem ceeb rau kev zam sigma-theem embrittlement hauv ntau qhov welds
Ib txhia yuav sib cav hais tias casting Incoloy800 yog impractical - dhau heev lawm rau shrinkage porosity, nyuaj heev rau pub. Tab sis peb cov xuab zeb-casting kab khiav kev cai gating systems tsim tshwj xeeb rau Fe-Ni-Cr alloys: ceramic-coated pwm, preheated rau 350 ° C, nrog rau kev taw qhia solidification tswj los ntawm txias txias thiab riser tso validated los ntawm MAGMAsoft simulation. Peb nrum Incoloy800 valve lub cev mus txog 120 kg - tsis yog raws li cov qauv, tab sis raws li cov khoom tsim nyog rau API 6A PR2. Tus yuam sij? Kev tswj cov kev sib tw ceev kom ± 0.3 mm / s hla ntu. Qhov ntawd tsis yog kev xav. Nws yog physics-tsav txheej txheem tsim.
Peb cov lus nug uas cov neeg siv khoom nquag tshaj plaws tsis yog "Koj puas tuaj yeem ua tau?" - nws yog "Kuv yuav ua li cas kom tsis txhob muaj qhov cuam tshuam uas tua peb cov khoom kawg?" Yog li peb embed engineering tshuaj xyuas thaum ntxov: GD&T validation tiv thaiv lub hom phiaj ua haujlwm (tsis yog kos duab ua raws), thermal expansion qauv rau flange mating, thiab txawm bolt-torque cov lus pom zoo raws li qhov tseeb yield zog ntawm cov khoom cua sov. Peb lub hlis dhau los, peb tau teeb tsa tus qauv tsim qhov twg cov phab ntsa tuab yuav tshaj qhov tseem ceeb ntawm qhov txias txias rau carbide nag lossis daus - qhia txog kev hloov pauv geometry es tsis txhob raug nqi tom qab kev kho cua sov. Qhov ntawd tau cawm peb lub lis piam thiab $ 18,000 hauv kev rov ua haujlwm dua.
Yog tias koj xav tau Incoloy800 cov khoom uas muaj sia nyob 30,000 teev ntawm 800 ° C yam tsis muaj qhov ntsuas, xau, lossis cuam tshuam - tom qab ntawd koj xav tau ntau dua li cov khoom siv raws li kev ua raws cai. Koj xav tau ib tus neeg koom tes uas kho cov tshuaj lom neeg hlau ua qhov pib, tsis yog qhov kawg. Leej twg nkag siab tias AMS 5387 cobalt nozzles thiab Incoloy800 twj tso kua mis sib koom tib lub hauv paus kev qhuab qhia: tswj microstructure los ntawm txhua kauj ruam txheej txheem. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua haujlwm qhov kev qhuab qhia txhua hnub - tsis yog raws li kev xav, tab sis raws li kev xyaum ua. Rau lub hom phiaj-kev ua haujlwm tseem ceeb, tsis muaj qhov hloov pauv rau kev paub dhau los hauv kev ua tsis tiav tiag tiag hauv ntiaj teb. Qhov ntawd yog qhov txhais tau tias muaj tseeb Incoloy800 Hoobkas.
