Thaum cov kws ua haujlwm hais txog grey hlau casting rau lub luag haujlwm siab hydraulic li qub lossis lub twj tso kua mis, lawv tsis yog xaiv cov khoom siv xwb - lawv tab tom twv ntawm qhov kev ruaj ntseg nyob rau hauv thermal cycling, zoo ib yam damping hauv vibrating systems, thiab kwv yees coj tus cwj pwm tom qab 10,000+ teev ua haujlwm. Yog vim li cas thiaj nrhiav tau ib grey hlau casting tuam txhab Hoobkas tsis tshua muaj pib nrog tus nqi - thiab yuav luag ib txwm xaus nrog cov txheej txheem tswj, metallurgical traceability, thiab xoom kam rau ua rau micro-shrinkage nyob rau hauv ib qho tseem ceeb load paths.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua haujlwm ib qho chaw hauv Qingdao - tsis yog ib qho chaw tsim khoom lag luam, tab sis raws li kev sib koom ua ke ntawm cov khoom sib xyaw ua ke qhov twg txhua qhov grey hlau casting ua tiav tag nrho cov batch-theem chemistry pov thawj tiv thaiv ASTM A48 Class 30B thiab EN-GJL-250 specifications. Peb tau pom cov neeg siv khoom rov qab xaj piston twj tso kua mis lub tog raj kheej lub tsev tom qab peb xyoos - tsis yog vim tias cov khoom ua tsis tiav, tab sis vim tias lawv cov khoom qub 2021 tseem tau ntsib GD&T callouts hauv ± 0.015 hli hla 12 datum nta. Qhov kev sib raug zoo ntawd tsis yog yuam kev. Nws tau ci rau hauv qhov cub hluav taws xob cov txheej txheem, pwm compaction siab cav, thiab tom qab cam khwb cia kev ntxhov siab-kho calibrated ib feem loj thiab seem thickness.
Dab tsi cais qhov no grey hlau casting tuam txhab Hoobkas los ntawm cov neeg muab khoom ntim ntim? Peb qhov kev ua haujlwm tiag tiag:
- Cov khoom siv yog tsis sib tham: Tag nrho cov khoom siv hlau grey pib nrog cov ntawv pov thawj npua hlau los ntawm ISO 9001 smelters - tsis muaj cov khoom seem uas tsis muaj kev tshuaj xyuas spectral. Txhua lub tshav kub muaj ib daim ntawv qhia txog zeb (MTR) khi rau nws cov lej ntau, thiab tensile tuav tau rub thiab sim ua ntej yuav pib ua haujlwm.
- Casting tsis cais - nws yog co-tsim nrog machining: Xuab zeb moulds suav nrog machinability pub nyiaj raws li qhov kawg CNC toolpaths. Piv txwv li, lub winch center ncej rau cov menyuam tau txais cov kab lus hauv zos tsuas yog qhov chaw milling nkag; Lwm qhov chaw, qhov chaw nyob twj ywm li-cam khwb cia graphite flake kev ncaj ncees thiab damping muaj peev xwm. Qhov kev xav hybrid no txiav tag nrho cov sij hawm txhuas los ntawm 22% ntawm qhov nruab nrab piv rau cov lus sib txuas.
- Kev tshuaj xyuas tsis yog kev saib xyuas - nws yog cov lus qhia: Txhua qhov casting dhau los ntawm Zeiss CONTURA CMM chaw nres tsheb ua ntej machining ntxhib. Kev sib txawv tsis yog sau cia nkaus xwb-lawv ua rau kev tshuaj xyuas hauv paus-ua rau kev tshuaj xyuas nrog cov kws tsim khoom tsim khoom. Ib tus neeg siv khoom rov ua dua qhov teeb meem tsis sib haum xeeb tau taug qab rov qab mus rau qhov tseem ceeb luam tawm deflection thaum shakeout. Qhov kho? Hloov kho cov tub ntxhais lub thawv clamping ib ntus-tsis yog kev hloov tsim.
Qee tus yuav sib cav hais tias grey hlau yog "cov khoom qub txeeg qub teg" - cuam tshuam los ntawm cov hlau hlau lossis hmoov hlau hauv cov ntawv thov kev ntxhov siab. Tab sis nyob rau hauv lub ntiaj teb no deployments, nws tuav qhov zoo sib xws: superior vibration damping nyob rau hauv lub twj tso kua mis foundations, txo nqi-ib-cubic-inch rau loj-section vaj tse, thiab pov thawj thermal qaug zog tiv thaiv nyob rau hauv roj & roj valve lub cev raug 50 ° C-200 ° C cycling. Qhov twg cov hlau nplaum tawg nyob rau hauv rov qab thermal shock, grey hlau feem ntau txhim kho ruaj khov, nws tus kheej txwv microcracks uas blunt ntxiv propagation. Peb tau lees paub qhov no nyob rau hauv qhov chaw-retrieved siab valve lub cev los ntawm North Hiav txwv platforms-tseem siv tau tom qab 17 xyoo, txawm tsis muaj txheej txheej.
Lub chaw txhawb nqa ob qho tib si zoo li qub thiab centrifugal casting txoj kev, tab sis rau cov khoom xav kom nruj phab ntsa tuab tswj-zoo li AMS 5387 cobalt alloy twj tso kua mis qhov chaw txuas ncaj qha mus rau grey hlau manifolds-qhov tsom nyob rau hauv cov xuab zeb casting nrog resin-bonded pwm. Vim li cas? Vim hais tias nws muab cov kev ywj pheej geometric xav tau rau cov cua txias sab hauv, mounting bosses, thiab kev sib foob grooves-tag nrho hauv ib lub ncuav. Tsis muaj kev sib dhos welds. Tsis muaj dej ntws. Tsis muaj cov txheej txheem sib koom ua ke thib ob cuam tshuam cov txheej txheem txuas ntxiv.
Rau cov pab pawg muag khoom ntsuas a grey hlau casting tuam txhab Hoobkas, nug cov lus nug no ua ntej kos npe rau NDA:
- Koj puas tuaj yeem muab MTRs thiab cov ntaub ntawv hardness rau peb lub tshav kub kawg uas siv rau ntawm peb tus lej?
- Yuav ua li cas koj txheeb xyuas graphite morphology - thiab dab tsi yog koj qhov kev tsis lees paub rau Hom D (degenerated) flakes nyob rau hauv qhov chaw tseem ceeb?
- Puas yog koj cov ntaub ntawv soj ntsuam suav nrog cov ntaub ntawv CMM cov ntsiab lus huab - tsis yog cov ntsiab lus dhau / tsis ua tiav?
- Dab tsi yog koj qhov kev hloov pauv siab tshaj plaws hauv qhov ntsuas kub ntawm ib qho pwm?
QINGDAO QIANGSENYUAN TECHNOLOGY teb yog rau tag nrho plaub-nrog cov ntaub ntawv pov thawj. Lawv txoj haujlwm ua raws ISO tsis nres ntawm kev ua haujlwm. Nws txuas ntxiv los ntawm kev kho cua sov validation (qhov twg tau teev tseg), multi-axis CNC ua tiav nrog cov txheej txheem kev soj ntsuam, thiab kev sim ua haujlwm zoo li kev kuaj xyuas hydrostatic siab ntawm 1.5 × ua haujlwm siab. Txhua cov khoom xa tuaj suav nrog cov ntaub ntawv txheeb xyuas qhov tseeb: yaj lub cav, daim ntawv qhia X-ray (yog tias xav tau), machining program version, thiab daim ntawv pov thawj kuaj zaum kawg kos npe los ntawm QA txhuas.
Qhov no tsis yog hais txog scaling output - nws yog hais txog scaling cia siab rau. Raws li kev lag luam khoom siv lifespans stretch tshaj 25 xyoo thiab hloov ib feem obsolescence ua ib tug saum toj-tier txaus ntshai, tus nqi ntawm ib tug grey hlau casting tuam txhab Hoobkas uas kho txhua qhov casting zoo li cov cuab yeej cuab tam-tsis yog cov khoom lag luam-tsuas yog nce ntxiv. Cov tiam tom ntej ntawm hydraulic systems yuav tsis xav tau ntau zog. Lawv yuav xav tau kev kwv yees ntau dua. Thiab qhov ntawd pib ntev ua ntej thawj lub ladle pours.
