Thaum cov kws tshaj lij qhia txog lub ntiajteb txawj nqus cam khwb cia hlau qhov chaw, lawv tsis yog tsuas yog xaj cov khoom siv-lawv tau cog lus rau kev ncaj ncees ntawm cov qauv hauv qab qhov siab, qhov ruaj khov nyob rau hauv lub voj voog thermal, thiab lub sij hawm ntev hnav tsis kam nyob rau hauv ib puag ncig tsis zoo. Yog vim li cas xaiv txoj cai gravity cam khwb cia hlau qhov chaw Hoobkas tsis yog ib qho khoom siv checkbox-nws yog qhov kev txiav txim siab theem. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb tau pom yuav ua li cas misaligned casting xyaum derail twj tso kua mis commissioning ncua sij hawm, yuav ua li cas hloov maj mam graphite morphology hloov kev cuam tshuam valve lub rooj sealing, thiab yuav ua li cas inconsistent shakeout lub sij hawm qhia micro-residual stress nyob rau hauv lub tog raj kheej vaj tse. Cov no tsis yog kev txhawj xeeb theoretical. Lawv yog hom kev ua tsis tiav uas peb kuaj xyuas txhua lub lim tiam.
Vim li cas lub ntiajteb txawj nqus Casting tseem yeej rau cov hlau tseem ceeb
Centrifugal lossis tuag casting tej zaum yuav muaj kev zam nruj dua ntawm cov geometries yooj yim - tab sis lub ntiajteb txawj nqus casting muab lub hom phiaj tseem ceeb ntawm hydraulic thiab roj & roj daim ntawv thov tiag tiag xav tau: tswj cov kev taw qhia solidification, kev kwv yees shrinkage them nyiaj, thiab metallurgical sib xws nyob rau hauv tuab seem. Peb niaj hnub nrum piston twj tso kua mis lub tog raj kheej vaj tse txog li 420 hli phab ntsa tuab nrog ASTM A48 Chav Kawm 350 tensile lub zog-thiab tuav GD&T txoj hauj lwm kam rau ua ntawm ± 0.15 hli ntawm qhov tseem ceeb mounting ntsej muag. Yuav ua li cas? Los ntawm kev sib koom ua ke ntawm cov xuab zeb pwm simulation (siv MAGMAsoft) nrog rau lub sij hawm ntawm qhov ntsuas kub ntsuas ntawm peb qhov tob thaum lub sij hawm nchuav. Qhov no tsis yog kev xav. Nws yog physics-tsav txheej txheem tswj.
Peb qhov chaw tsim khoom siv rov ua dua silica xuab zeb sib txuas nrog furan resin - txheeb xyuas ISO 22988 rau kev coj tus cwj pwm decomposition. Tab sis kev xaiv cov khoom ib leeg tsis lav kev ua haujlwm. Peb tau pom tias tsis muaj kev tswj xyuas qhov txias txias qis dua 120 ° C / teev ua rau Hom D graphite tsim hauv ASTM A278 Qib 65-45-12 cov hlau nplaum - ncaj qha cuam tshuam rau 23% qis qaug zog lub neej hauv winch center ncej chais. Yog li peb tswj hwm cov txheej txheem cua txias cua txias calibrated ib feem pawg thiab seem modulus. Txhua batch nqa tag nrho traceability: yaj tooj, pouring kub, txias nkhaus nqes hav, thiab zaum kawg hardness pov thawj.
Qhov twg Machining ntsib Casting-Thiab yog vim li cas Vertical Integration Matters
Lub ntiajteb txawj nqus casting teeb lub hauv paus. Precision machining muab qhov chaw ua haujlwm. Kev cais cov txheej txheem no caw kom muaj kev pheej hmoo. Peb tau taug qab 68% ntawm qhov tsis sib xws ntawm qhov tsis sib xws hauv cov neeg thib peb cov cav tov rau datum hloov ntawm casting thiab CNC teeb tsa-tshwj xeeb tshaj yog ntawm asymmetrical twj tso kua mis lub hauv paus nrog ntau lub dav hlau mounting. Peb qhov kev daws teeb meem? Cast-to-machined workflow tswj: tib tus neeg teb xov tooj CMM txheeb xyuas qhov ntev li-cam khwb cia * thiab * tiav geometry; tib fixture nrhiav ob theem; tib metrology lab validates ua ntej thiab tom qab kev kho cua sov.
Qhov kev sib koom ua ke no ua rau muaj cov yam ntxwv zoo li AMS 5387 cobalt alloy inserts nias-haum rau hauv cam khwb cia hlau vaj tsev - qhov twg thermal expansion mismatch yuav tsum tau ua qauv rau ± 0.002 hli cuam tshuam. Los yog T800-raws li nozzles nrog 0.05 hli phab ntsa thickness kam rau ua, machined ncaj qha los ntawm raws li-cam khwb cia blanks tsis muaj kev ntxhov siab-relieving distortion. Peb tsis outsource kev kho cua sov. Peb lub tshuab nqus tsev vacuum khiav cov ntawv pov thawj rau ib qho AMS 2750E, nrog kev nkag mus txuas ntxiv pyrometer. Vim tias thaum koj lub siab valve ua haujlwm ntawm 415 bar, "kaw txaus" tsis yog qhov kev xaiv.
Qhov tseeb tiag-Lub Ntiaj Teb Validation zoo li
Cov neeg siv khoom nug: "Koj ua pov thawj kev ntseeg tau li cas?" Tsis yog nrog daim ntawv pov thawj ib leeg-tab sis nrog cov ntaub ntawv xeem. Peb cov cobalt-nickel alloy plugs raug 10,000-lub voj voog yaig kuaj hauv 3.5% NaCl brine ntawm 85 ° C, simulating offshore twj tso kua mis. Cov txiaj ntsig qhia <1.2 μm / xyoo cov khoom poob - piv rau kev lag luam-nruab nrab 4.7 μm / xyoo. Rau engineering tsheb winch rollers, peb siv tau qhov kev ncaj ncees ntawm qhov chaw siv Barkhausen suab tsom xyuas kom pom qhov sib tsoo subsurface kub tsis pom los ntawm kev tshuaj xyuas qhov muag. Thiab txhua qhov khoom xa tuaj suav nrog cov ntaub ntawv pov thawj tag nrho: OES spectrography cov ntaub ntawv, tensile test curves, thiab microstructure duab annotated ib ASTM E112.
Peb kuj qhia cov kev kawm nyuaj. Piv txwv li: thaum ntxov batch ntawm tsis-tus qauv twj tso kua mis flanges qhia ntxov ntxov gasket to. Hauv paus ua rau? Pwm venting tsis txaus rau high-backpressure pours. daws? Rov tsim cov ntawv luam tawm tshiab nrog 0.3 hli radial vents - txheeb xyuas los ntawm X-ray CT scan. Tam sim no cov flanges ua tiav xoom xau ntawm 1.8 × ntsuas siab. Qhov ntawd yog qhov sib txawv ntawm tus neeg muag khoom thiab tus khub.
