Thaum cov kws tshaj lij qhia cov xuab zeb stainless hlau casting rau high-pressure hydraulic li qub lossis offshore twj tso kua mis vaj tse, lawv tsis yog xaiv cov khoom siv xwb - lawv tab tom twv rau qhov ruaj khov, kev tiv thaiv corrosion, thiab microstructural sib xws nyob rau hauv lub ntiaj teb thermal thiab mechanical stress. Yog vim li cas xaiv txoj cai stainless hlau xuab zeb casting foundry Hoobkas teeb meem ntau tshaj li kev zam rau ntawm daim ntawv. Peb tau pom ntau txoj haujlwm qeeb - tsis yog los ntawm kev tsim teeb meem, tab sis los ntawm cov chaw tsim khoom uas kho cov xuab zeb casting raws li cov txheej txheem khoom lag luam es tsis yog kev qhuab qhia metallurgical.
Stainless hlau xuab zeb casting tsis zoo li grey hlau lossis txhuas. Nws lub siab melting point (1400-1500 ° C), rhiab heev rau qhov txias txias, thiab nyiam mus rau interdendritic segregation xav kom nruj tswj pwm permeability, binder chemistry, pouring kub, thiab shakeout sij hawm. A 2 ° C sib txawv hauv preheat tuaj yeem ua rau microporosity hauv ASTM A351 CF8M valve lub cev. Ib qho 0.3 hli tsis sib haum nyob rau hauv kev sib raug zoo hauv cov tub ntxhais kawm tuaj yeem cuam tshuam lub siab ntim hauv piston twj tso kua mis lub tog raj kheej nyob rau 350 bar. Cov no tsis yog qhov kev pheej hmoo theoretical. Lawv yog thaj chaw ua tsis tiav peb tau kuaj pom hauv peb North American cov chaw pabcuam roj av-txhua qhov rov qab mus rau cov qauv nplej tsis sib haum thoob plaws cov khoom pov tseg.
Dab tsi cais lub peev xwm stainless hlau xuab zeb casting foundry Hoobkas los ntawm kev lag luam muag khoom? Ua ntej: ntsug kev koom ua ke dhau casting ib leeg. Koj xav tau ib tus khub uas tshuab tib yam * tom qab * casting-vim tsuas yog tom qab ntawd lawv puas hnov qhov tshwm sim ntawm kev ntxhov siab, carbide banding, lossis tsis sib xws. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., CNC machining tsis yog add-on; nws yog qhov kawg validation kauj ruam. Thaum lawv ua tiav T800 cobalt-based winch center ncej cov menyuam, lawv txheeb xyuas qhov sib npaug ntawm tsib txoj haujlwm axial - tsis yog nyob rau hauv chav tsev kub xwb, tab sis tom qab simulated 120 ° C ua haujlwm ntub dej. Qhov no yog li cas koj ntes distortion ua ntej nws mus txog lub rooj sib txoos kab.
Thib ob: cov khoom siv traceability uas nkag mus tob dua li cov ntawv qhia txog zeb. Cov qib stainless hlau zoo li AMS 5387 lossis ASTM A743 CA15 tsis coj tus cwj pwm tsis sib xws hauv cov cua sov-txawm tias muaj cov npe zoo sib xws. Kev hloov pauv me me hauv cov ntsiab lus nitrogen lossis delta ferrite qib hloov ua haujlwm, kev kho cua sov, thiab lub neej qaug zog. QINGDAO QIANGSENYUAN tswj kev koom tes nrog cov khoom siv raw cov ntaub ntawv pov thawj, hla kev xa mus rau txhua qhov cua sov tiv thaiv nws tus kheej hauv tsev tensile thiab Charpy V-notch cov ntaub ntawv. Yog tias tus neeg siv khoom thov 22% qhov elongation yam tsawg kawg nkaus hauv CF3M casting, lawv tsis tsuas yog lees txais tus neeg muag khoom daim ntawv pov thawj - lawv siv tau nws ntawm lawv tus kheej lub tshuab kuaj, siv cov qauv txiav los ntawm qhov tseeb qhov rooj ntawm lub ncuav.
Thib peb: kev soj ntsuam nruj uas tsom iav qhov kawg-siv qhov hnyav. Feem ntau cov foundries ntsuas qhov loj me me nrog CMMs-tab sis ob peb tshuaj xyuas rau subsurface kev ncaj ncees nyob rau hauv cov xuab zeb-cam khwb cia stainless qhov chaw. QINGDAO QIANGSENYUAN siv phased array ultrasonic kuaj (PAUT) ntawm tag nrho cov siab-muaj cov khoom tuab dua 25 hli, luam theej duab rau cov kab ntawv qhia ua raws li kev loj hlob dendrite. Rau qhov tsis muaj kev ntxhov siab xws li engineering tsheb twj tso kua mis lub hauv paus, lawv siv cov tshuaj pleev xim rau kev soj ntsuam * tom qab * kev ntxhov siab-relieving - thiab dua tom qab kawg machining - mus ntes rov qhib microcracks. Txhua daim ntawv tshaj tawm suav nrog daim ntawv qhia chaw nyob, tsis yog daim ntawv hla dhau / poob.
Plaub: tsim-rau-tsim kev txawj ntse-tsis yog kev txhais lus GD&T nkaus xwb, tab sis kev tawm tswv yim tawm tswv yim hauv paus hauv kev tsim lub cev. Piv txwv li: thaum tus neeg siv khoom xa daim duab hu rau ± 0.05 hli kam rau ntawm 320 mm inch flange ntsej muag, lawv pab neeg tsis hais lossis tsis lees paub. Lawv tau ua qauv ua kom muaj zog shrinkage siv MAGMAsoft, txheeb xyuas qhov yuav ua rau muaj kev sib ntaus sib tua, thiab tau thov kom tshem tawm ob daim ntawv luam tawm kom sib npaug thermal gradients. Qhov tshwm sim? Txo cov khoom lag luam tom qab kev tshem tawm los ntawm 40%, tshem tawm ib qho kev ua tiav yam tsis muaj kev cuam tshuam rau kev ua haujlwm. Qhov ntawd tsis yog kev pabcuam - nws yog kev sib koom ua haujlwm kev pheej hmoo txo qis.
Yog lawm, stainless hlau xuab zeb casting nqa cov nqi siab dua li kev nqis peev casting rau cov khoom me me-lossis tuag casting rau cov khoom tsis-ferrous. Tab sis rau cov khoom ntim nruab nrab ntawm cov khoom xws li hydraulic siab li qub (50-500 pcs / xyoo), lub tog raj kheej lub tog raj kheej nrog cov cua txias sab hauv, los yog cov twj tso kua mis tawm sab nrauv, cov xuab zeb casting muab qhov tsis sib haum xeeb hauv qhov loj, kev xaiv alloy, thiab phab ntsa thickness variation. Thiab thaum koj ib feem yuav tsum muaj sia nyob chloride-laden seawater, cyclic loading, thiab xoom-leak xav tau, kev ntseeg siab tsis raug nqi ib kilogram-nws yog luv nqi rau zam tsis ua hauj lwm.
Yog tias koj ntsuas a stainless hlau xuab zeb casting foundry Hoobkas, nug peb nqe lus nug ua ntej kos npe rau NDA: Lawv puas tuaj yeem qhia koj daim ntawv tshaj tawm PAUT tsis ntev los no rau CF8M casting piv rau koj qhov geometry? Lawv puas khaws cov ntaub ntawv pov tseg - suav nrog qhov ntsuas kub, ntsuas lub ladle, thiab pwm preheat - rau txhua pawg xa khoom? Thiab puas yog lawv puas tau tsis lees paub lawv tus kheej casting vim tias tom qab siv lub tshuab ua kom pom qhov txawv txav tsis tau xav txog qhov nyuaj? Cov lus teb rau tag nrho peb qhia koj ntau dua li daim ntawv pov thawj ISO.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua haujlwm los ntawm Qingdao - tsis yog lub tuam txhab kev lag luam outsourcing casting, tab sis raws li cov chaw tsim khoom siv thev naus laus zis uas cov kws tshawb fawb metallurgists tshuaj xyuas cov cav ntoo nrog CNC programmers. Lawv lub hom phiaj nyob qis qis: cov khoom lag luam precision qhov chaw ua haujlwm dictates daim ntawv, thiab qhov twg "zoo txaus" txhais tau tias tsis ua hauj lwm teb. Qhov kev qhuab qhia yog vim li cas lawv cov xuab zeb stainless hlau castings xa mus rau hydraulic OEMs hauv lub teb chaws Yelemees, subsea cov khoom sib koom ua ke hauv Singapore, thiab cov neeg tsim tsheb mining hauv Canada - tsis yog vim lawv pheej yig tshaj plaws, tab sis vim tias lawv yog tus xa khoom zaum kawg hu rau thaum thawj tus qauv ua tsis tiav kev sim vibration.
