Thaum engineers qhia a casting qhov chaw Hoobkas rau lub hom phiaj tseem ceeb hydraulic li qub los yog high-wear winch shafts, lawv tsis yog tsuas yog yuav hlau - lawv tab tom yuav qhov kev ruaj ntseg nyob rau hauv 350-bar siab, microstructure kev ncaj ncees tom qab kev kho cua sov, thiab tag nrho batch traceability mus rau yaj tooj. Tias yog vim li cas cov pab pawg tsim hauv North America thiab Europe tau nce txoj hauv kev sib xyaw cobalt-alloy twj tso kua mis rau Qingdao - tsis yog rau tus nqi qis, tab sis rau kev kwv yees tus cwj pwm metallurgical thiab xoom-xws li kev xa khoom.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Ua haujlwm qhov kev ua haujlwm siab ua tau raws li kev ua haujlwm tau zoo: ± 0.05 hli ntawm piston twj tso kua mis lub tog raj kheej vaj tse, AMS 5387 ua raws li kev txheeb xyuas ntawm ASTM E112 grain loj tsom xam, thiab nto tiav rau Ra 0.8 µm ntawm cobalt-nozzle sealing ntsej muag. Peb tau pom cov neeg siv khoom hloov pauv tom qab peb qhov ua tsis tiav ntawm T800 alloy plugs-txhua lub sijhawm, hauv paus ua rau taug qab mus rau qhov tsis sib xws ntawm carbide dispersion thaum lub sij hawm solidification. Qiangsenyuan zam qhov no los ntawm kev tswj cov xuab zeb pwm permeability * thiab * tom qab cam khwb cia tshuaj annealing ramp tus nqi hauv tsev. Tsis muaj tes tuav. Tsis muaj kev xav.
Lawv txoj kev sib koom ua ke ntsug tsis yog lus lag luam - nws yog qhov tsim nyog. Siv lub tshuab hluav taws xob winch center ncej cov menyuam: cam khwb cia hlau (ASTM A), ntxhib-machined ntawm 5-axis DMG Mori, kub-kho rau 28-32 HRC, tom qab ntawd ua tiav-hauv av nrog cov lus qhia CMM. Txhua kauj ruam nyob hauv ib lub ru tsev. Qhov ntawd tshem tawm qhov dav dav dav dav thaum cov khw muag khoom xa khoom xa tuaj rau cov khw muag khoom sab nraud-tshwj xeeb yog qhov tseem ceeb thaum cov ntawv xov xwm yuav tsum tau khiav tawm hauv qab 0.015 hli. Cov neeg siv khoom tau tshaj tawm 40% tsawg dua thawj tsab ntawv tsis lees paub piv rau cov qauv ua ntej ntau qib.
Kev qhuab qhia ntawm cov khoom siv tsis yog sib tham ntawm no. Raw cobalt-nickel ingots tuaj txog nrog zeb xeem ntawv qhia qhia carbon ≤0.12%, chromium 27-31%, thiab cobalt ≥60% - txheeb xyuas ua ntej melting. Thaum lub twj tso kua mis nyob sab Europe OEM thov nruj dua tswj cov ntsiab lus delta ferrite hauv stainless hlau castings, Qiangsenyuan tsis yog kho chemistry; lawv tau teeb tsa lub tes tuav PMI spectrometer ntawm qhov chaw tso dej thiab sau txhua qhov kev sib xyaw ua ke tiv thaiv cov nkhaus nkhaus. Qib ntawm kev tswj granular piav qhia vim li cas lawv cov khoom AMS 5387 tsis tu ncua dhau NDT Qib III kev tshuaj xyuas ultrasonic - tsis muaj kev rov ua dua, tsis muaj seem.
Kev xa khoom tiag tiag hauv ntiaj teb pob khawm ntawm kev sib koom ua ke ntawm engineering - tsis yog lub peev xwm tsim khoom xwb. Thaum lub sij hawm GD&T tshuaj xyuas ntawm lub siab valve lub tsev teeb duab, lawv pab neeg tau tshaj tawm 0.02 hli profile kam rau ua rau lub ntsej muag tsis ua haujlwm. "Peb tuaj yeem tuav tau," lawv hais tias, "tab sis nws ntxiv 17% lub sijhawm ua haujlwm thiab tsis muaj txiaj ntsig zoo." Lawv tau thov kom so nws mus rau 0.1 hli, tau lees paub qhov kev hloov pauv nrog FEA daim ntawv qhia kev ntxhov siab, thiab sib koom ua ke thermal expansion simulations qhia tsis muaj kev cuam tshuam rau kev sib khi. Qhov kev sib koom tes daws teeb meem - hauv paus hauv physics, tsis yog kev muag khoom cog lus - yog qhov hloov ib qho kev txiav txim rau hauv kev koom tes ntau xyoo. Rau cov pab pawg xav tau precision hlau casting kev daws teeb meem uas coj raws li kev kwv yees, tsis yog raws li kev cia siab, txoj hauv kev pib nrog kev tshuaj xyuas - tsis yog daim ntawv thov.
