Xuab zeb casting qhov chaw tseem yog cov pob txha ntawm cov khoom siv hnyav-tsis yog vim tias lawv dhau los, tab sis vim lawv xa cov khoom siv tsis sib xws, qhov ruaj khov, thiab kev tswj tus nqi uas nws tseem ceeb tshaj plaws: hauv hydraulic manifolds, oilfield valve lub cev, thiab cov twj tso kua mis siab.
Peb tau nrum tshaj 12,000 xuab zeb casting qhov chaw rau engineering tsheb OEMs nyob rau hauv 18 lub hlis dhau los ib leeg. Hauv txhua pawg, ib qho tseeb rov hais dua: thaum phab ntsa thickness tshaj 25 hli, kev khiav hauj lwm siab nce siab tshaj 350 bar, los yog kev pab cuam lub neej yuav tsum tshaj 15 xyoo - xuab zeb casting tsis yog ib qho kev xaiv poob. Nws yog tib txoj kev uas sib npaug metallurgical kev ncaj ncees nrog manufacturability rau loj, complex geometries.
Tsis zoo li peev casting, uas ua tau zoo nyob rau hauv nyias-walled precision tab sis tawg nyob rau hauv thermal cycling kev nyuaj siab, xuab zeb casting muab superior damping peev thiab tawg kuj nyob rau hauv ferrous thiab high-alloy systems. Peb tau pom cobalt-nickel alloy (AMS 5387) lub tog raj kheej vaj tse muaj sia nyob 40,000+ lub voj voog siab nyob rau hauv cov twj tso kua mis tawm sab nrauv-tsuas yog vim cov xuab zeb pwm me ntsis permeability tso cai tswj kev ua kom muaj zog, txo qis hauv nruab nrab thiab micro-porosity.
Peb qhov kev muaj tiag cais cov xuab zeb casting qhov chaw los ntawm seem:
- Core sib dhos kam rau ua: ± 0.3 hli sib txawv hauv qhov kev tso kawm tseem ceeb tsim cov phab ntsa tsis sib xws - thiab 73% ntawm lub neej thaum ntxov qaug zog peb tau txheeb xyuas kab rov qab rau qhov sib txawv no.
- Binder system xaiv: Phenolic urethane tsis muaj ci binders ua tau zoo tshaj cov av nplaum-raws li tshuab rau T800 cobalt alloy pours, txo cov roj tsis xws luag los ntawm 68% nyob rau hauv tuab-section castings.
- Kev ntxhov siab tom qab kev ntxhov siab: Ib 4-teev ntub dej ntawm 920 ° C ua raws li qhov cub txias yog tsis sib tham rau piston twj tso kua mis - hla nws nce GD&T sib txawv txog li 0.15 hli ntawm qhov tseem ceeb datum nto.
Kev siv nyiaj txiag tsis yog tsuas yog txo cov cuab yeej xwb. Nws yog hais txog kev tshem tawm cov haujlwm thib ob. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb koom ua ke machining datums ncaj qha rau hauv cov qauv tsim - yog li cov xuab zeb casting ib feem tuaj txog ntawm CNC cell npaj rau kev ua tiav, tsis yog ntxhib milling. Qhov ntawd txiav lub sij hawm ua cov hmoov txhuas los ntawm 3.2 hnub rau ib qho kev txiav txim thiab txo qhov teeb meem kev teeb tsa los ntawm 41%. Peb tsis "cam khwb cia ces tshuab." Peb nrum * rau * machining.
Qee qhov sib cav tias 3D-luam xuab zeb pwm tshem tawm cov qauv nqi tag nrho. Tab sis nyob rau hauv lub ntiaj teb no ntau lawm, luam pwm tsis muaj lub zog compressive xav tau rau loj hlau castings saum 120 kg. Peb tau sim ob qho tib si: cov pwm luam tawm ua tsis tiav ntawm 142 bar ncuav siab; tsoos resin-coated silica pwm tuav ntawm 198 bar-nrog xoom hlawv-hauv lossis pwm yaig. Kev lag luam tawm tsis yog theoretical - nws yog ntsuas hauv tus nqi tawm los. Peb cov xuab zeb casting tam sim no dhau tus nqi sawv ntawm 99.1%, txheeb xyuas los ntawm CMM scanning ntawm txhua qhov tseem ceeb bores thiab sealing nto ua ntej kev kho cua sov.
Cov ntaub ntawv traceability tsis yog cov ntaub ntawv-nws yog physics. Txhua qhov ntau ntawm ASTM A27 Qib WCB steel lossis AMS 5387 cobalt alloy nqa tag nrho cov ntawv pov thawj zeb, cov ntaub ntawv txheeb xyuas spectral, thiab cov ntaub ntawv ntsuas tensile tau sau tawm tsam tus lej casting. Thaum ib tus neeg siv khoom hauv Norway tau thov kom muaj qhov tsim nyog ntawm 2019 winch center ncej ncej cov menyuam batch, peb rub tus thawj yaj lub cav, pom cov qauv ladle tiag tiag, thiab paub tseeb tias qhov hardness tseem nyob hauv ± 2 HRC tom qab yim xyoo hauv sub-zero marine cia.
Kev tswj hwm qib no los ntawm kev sib koom ua ke ntsug: peb lub chaw ISO-raws li kev tswj hwm txhua yam ntawm ntsuab-xuab zeb molding thiab shakeout mus rau T6 kev kho cua sov, tua blasting, thiab kev soj ntsuam zaum kawg siv optical comparators calibrated rau NIST qauv. Tsis muaj handoffs. Tsis muaj batch khoob. Tsuas yog ib pab neeg lav ris rau txhua qhov micron ntawm qhov raug qhov tseeb thiab txhua qhov joule ntawm kev cuam tshuam.
Xuab zeb casting qhov chaw ua tiav thaum engineers kho lawv li engineered systems-tsis yog hlau duab. Qhov ntawd txhais tau hais tias tsim cov duab cua ntsawj ntshab ib ncig ntawm cov cuab yeej tshem tawm txoj hauv kev, qhia qhov chaw nce siab raws li thermal gradient qauv - tsis yog kev lig kev cai - thiab xaiv cov alloys raws li cov pob txha toughness nkhaus, tsis yog lub rooj tensile zog xwb. Peb tau tso tseg 17 tsab ntawv thov hauv 2024 vim tias GD&T callouts tsis sib haum xeeb nrog cov qauv ua kom muaj zog. Zoo dua hais tias "tsis yog" dua li nkoj ib feem uas ua tsis tau ntawm 3,200 psi.
Yog tias koj daim ntawv thov xav kom muaj kev ncaj ncees nyob rau hauv lub voj voog load, corrosion resistance nyob rau hauv qaub-gas ib puag ncig, los yog seem rov ua dua nyob rau hauv 500-unit khiav-xuab zeb casting qhov chaw tsis yog legacy tech. Lawv yog cov kev daws teeb meem uas tsim los rau kev ua haujlwm tseem ceeb. Thiab lawv pib paub qhov tseeb qhov twg cov hlau molten yuav ntws, txias, thiab kaw hauv cov qauv lis-ua ntej thawj cov xuab zeb kov cov qauv.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. tsim cov xuab zeb casting qhov chaw rau cov neeg siv khoom thoob ntiaj teb uas ntsuas kev ua tiav hauv lub sijhawm ua haujlwm - tsis yog nqi tsev. Lawv txoj haujlwm ua pov thawj tias kev ua haujlwm ntev thiab kev siv nyiaj tsis sib tw. Lawv sib xyaw.
