Thaum cov engineers qhia meej steel precision casting qhov chaw Hoobkas rau siab kam rau ua lag luam Cheebtsam, lawv tsis yog tsuas yog xaj hlau-lawv tab tom ua haujlwm ruaj khov nyob rau hauv 350 bar hydraulic siab, tiv thaiv abrasive slurry ntawm 120 ° C, los yog tswj ± 0.015 hli roundness nyob rau hauv lub rotating twj tso kua mis ncej tom qab kev khiav hauj lwm 10.000 teev. Qhov kev ntseeg siab ntawd tsis yog los ntawm cov chaw tsim khoom lag luam. Nws los ntawm cov neeg koom tes uas kho metallurgy li engineering - tsis yog kev tsim khoom.
Vim li cas qhov kev ruaj ntseg pib ntev ua ntej cov pwm yog nchuav
Feem ntau qhov ua tsis tiav hauv cov tsev siab siab siab lossis lub piston twj tso kua mis cylinders rov qab mus rau ib qho hauv paus ua rau: tsis sib haum xeeb microstructure hla cov khoom siv hluav taws xob. Peb tau pom nws ntau zaus - qhov chaw dhau CMM tshuaj xyuas ntawm chav tsev kub, tom qab ntawd warp thaum lub sijhawm ua haujlwm vim muaj kev ntxhov siab los ntawm qhov tsis sib xws hauv cov xuab zeb casting lossis cov nplej sib cais hauv cov khoom noj uas tsis huv. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., txhua lub hlau thiab stainless hlau casting pib nrog ntawv pov thawj raw khoom pov thawj-tsis yog zeb ntawv pov thawj, tab sis qhov tseeb spectrographic tsom xam ntawm txhua yaj ntau. Peb hla-xyuas carbon sib npaug, delta ferrite cov ntsiab lus, thiab intergranular corrosion susceptibility ua ntej pouring. Yog li peb tuav ± 0.02 hli kam rau ntawm 300 hli OD lub tog raj kheej bores- tsis yog qhov kev xeem ib zaug, tab sis hla 500-unit ntau lawm khiav.
Qhov twg casting xaus thiab precision pib
Kev nqis peev casting muab net-shape geometry. Xuab zeb casting tuav qhov loj thiab thermal loj. Tab sis ob leeg tsis xa cov chaw ua haujlwm kawg nkaus ib leeg. Tias yog vim li cas kev sib koom ua ke ntsug tsis yog lo lus lag luam ntawm no - nws yog tib txoj hauv kev los tswj kev cuam tshuam. Ib tug cobalt-nickel alloy twj tso kua mis vaj tse cam khwb cia nyob rau hauv silica-bonded xuab zeb yuav nce 0.12 hli ntawm thermal loj hlob thaum lub sij hawm kev daws annealing. Yog tias machining tshwm sim ntau lub lis piam tom qab, yam tsis muaj kev ntxhov siab lossis kev ntxhov siab ua ntej kev txiav tiav, qhov kev loj hlob ntawd txhais ncaj qha rau hauv GD&T kev ua txhaum cai ntawm qhov tseem ceeb datum nta. Peb lub chaw ua haujlwm kho cua sov, txo kev ntxhov siab, thiab ntau lub axis CNC machining hauv 72 teev - thiab ntsuas txhua kauj ruam nruab nrab siv Zeiss CONTURA G2 CMMs ntsuas rau ISO 10360-2. Rau AMS 5387 cobalt alloy 6 Cheebtsam, peb siv kev cai carbide tooling nrog optimized chip-breaker geometry thiab cryogenic coolant xa - tsis yog vim nws yog "advanced," tab sis vim standard HSS cov cuab yeej deflect 0.04 hli thaum profiling T800 alloy nozzles nrog 0.8 hli phab ntsa thickness.
Tus nqi tiag tiag ntawm "tsis yog-tus qauv" tsis yog nyob rau hauv nqe lus - nws yog nyob rau hauv rework
Cov neeg siv khoom feem ntau nug: "Koj puas tuaj yeem ua qhov tsis yog qhov chaw nruab nrab ntawm cov menyuam yaus?" Qhov lawv tsis hais - tab sis qhov peb soj ntsuam thaum lub sij hawm kev tshuaj xyuas engineering - yog seb qhov twg yuav tsum muaj sia nyob torsional shock loads ntawm 22 kN·m thaum tig ntawm 45 rpm hauv huab cua ntsev-laden marine. Qhov ntawd hloov txhua yam: cov khoom siv qib (F22 vs. F22 CL3), lub voj voog kho cua sov (normalizing + tempering vs. quench & temper), nto tiav (Ra 0.8 µm av vs. Ra 0.4 µm honed), thiab txawm ntim (vapor-corrosion-inhibiting ntawv, tsis qhwv yas). Peb chij cov no thaum ntxov - tsis yog ua kom nyuaj rau kev txiav txim, tab sis tiv thaiv kev ua tsis tiav. Ib tus neeg tau txais kev cawmdim $89,000 hauv lub sijhawm poob los ntawm kev kho lub chamfer lub kaum sab xis ntawm lub rooj zaum siab ntawm 15 ° txog 22 ° - qhov kev hloov pauv uas txo qis kev vibration thiab txuas ntxiv lub neej ntawm 4 mus rau 11 lub hlis. Qhov kev nkag siab ntawd tau los ntawm peb qhov kev sib tham GD&T, tsis yog pob ntawv kos duab.
Kev ntseeg tsis tau ntawv pov thawj - nws tau txheeb xyuas, batch los ntawm batch
Kev ua raws li ISO 9001 tau txais koj hauv qhov rooj. Tag nrho traceability ua rau koj nyob rau hauv cov khoom siv. Txhua steel precision casting qhov chaw Hoobkas thov kev tswj kom zoo. Ob peb khaws cov ntaub ntawv ntau theem: cov xov tooj cua sov, hnub ncuav, qhov cub ID, daim ntawv qhia tensile, hardness mapping hla ntu tuab, thiab CMM scan cov ntaub ntawv khaws tseg rau 10 xyoo. Peb ua. Thaum ib tug European OEM thov tag nrho microstructural tsom xam ntawm kev xa khoom ntawm stainless hlau winch shafts, peb muab SEM dluab qhia austenite grain loj faib - tsis yog "ua tau raws li ASTM A351 CF8M." Lub pob tshab ntawd tsis yog xaiv tau. Nws yog li cas peb ua raws li API 6A, EN 1515-2, thiab ASME B16.34 cov kev cai yam tsis muaj kev cuam tshuam hauv kev tshawb xyuas thib peb rau txhua PO. Peb cov kev ua haujlwm ntshiv tsis txi qhov nruj-nws embeds nws: kev tshuaj xyuas cov khoom tuaj, thawj tsab ntawv validation, in-process checks at 20% and 70% tiav, thiab kawg functional testing on hydraulic test bench up to 700 bar.
Yog tias koj qhov project tom ntej no xav tau steel precision casting qhov chaw Hoobkas muaj peev xwm - tsis yog casting xwb, tab sis tswj metallurgy, txheeb xyuas qhov ruaj khov, thiab xoom-kev cuam tshuam traceability - pib nrog kev sib raug zoo, tsis yog daim ntawv nqe. Tus khub zoo tsis yog ua raws li cov qauv. Lawv cia siab tias qhov twg cov specs poob luv luv hauv kev ua haujlwm tiag tiag.
