Thaum cov kws tshaj lij qhia txog lub ntiajteb txawj nqus tuag casting rau cov khoom siv hlau ua haujlwm siab, lawv tsis yog xaiv cov txheej txheem xwb - lawv xaiv tus khub muaj peev xwm tuav ± 0.05 mm kam rau ua rau ntawm cobalt alloy twj tso kua mis vaj tse thaum tuav microstructural kev ncaj ncees nyob rau hauv 350 bar kev khiav hauj lwm siab. Qhov theem ntawm qhov sib xws cais a Lub ntiajteb txawj nqus tuag casting Hoobkas los ntawm cov khoom tsim nyog.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua haujlwm qhov nqaim nqaim txhua hnub. Raws li nyob rau hauv Qingdao, Tuam Tshoj, lub tuam txhab muab kev ua hauj lwm cam khwb cia cov khoom uas tsis ua hauj lwm yog ib qho kev xaiv: piston twj tso kua mis lub tog raj kheej vaj tse rau hydraulic systems, center ncej rollers rau engineering tsheb winches, AMS 5387 cobalt alloy 6 twj tso kua mis rau oilfield kev pab cuam cov cuab yeej. Cov no tsis yog prototypes lossis ib-tawm. Lawv yog cov khoom tsim nrog tag nrho cov ntaub ntawv traceability, cov ntaub ntawv kho cua sov, thiab CMM-tshuaj xyuas GD&T ua raws - xa mus rau OEMs thoob plaws North America, Europe, thiab Southeast Asia.
Dab tsi ua rau lawv lub ntiajteb txawj nqus tuag casting muaj peev xwm sib txawv tsis yog cov cuab yeej siv xwb - nws yog li cas lawv kho metallurgy raws li tus qauv tsim. Feem ntau cov neeg muag khoom tau muab cov khoom ua ntej-alloyed thiab ncuav qhov muag tsis pom kev. QINGDAO QIANGSENYUAN koom tes ncaj qha nrog cov neeg muag khoom tau ntawv pov thawj kom siv tau cov batch-specific tensile zog, grain loj faib, thiab carbide dispersion * ua ntej * pwm npaj. Rau T800 cobalt-raws li alloys, uas txhais tau tias kom paub tseeb tias hardness nyob twj ywm nyob rau hauv 42-46 HRC tom qab tov annealing - thiab xyuas nws dua tom qab machining. Peb tau pom cov neeg siv khoom hloov pauv los ntawm cov neeg xa khoom peb-tier mus rau kev sib koom tes ncaj qha tom qab pom qhov tsis sib haum xeeb ntawm kev sib cais ntawm cov neeg sib tw hauv kev sib tw ua rau muaj kev cuam tshuam ntxov ntxov nozzle yaig nyob rau hauv txoj kev ua kua dej siab.
Lawv vertically integrated workflow tshem tawm handoff yuam kev uas degrade precision. Lub ntiajteb txawj nqus tuag casting tshwm sim nyob rau hauv ISO-raws li bays nrog tswj pwm preheat (220-260 ° C), calibrated pouring kub qhov rais (± 5 ° C), thiab real-time thermal xyuas thaum lub sij hawm solidification. Tsis muaj lwm yam re-melting. Tsis muaj qhov chaw machining. Kev ua haujlwm CNC ua raws tam sim ntawd-ntawm 5-axis cov cav tov muaj peev xwm ntawm contouring cov cua txias channel hauv 40-mm-thick cylinder vaj tse thaum tuav txoj haujlwm tseeb hauv 0.015 hli. Kev kho cua sov sib xyaw ua ke hauv kab: kev daws anneal, quench, thiab kev laus tshwm sim yam tsis muaj kev hloov chaw. Deg xov-electropolishing, txhaj tshuaj peening, los yog HVOF txheej-yog teev raws li kev xav tau, tsis yog catalog xaiv.
- Siab li qubCasting hauv ASTM A494 M35-1, machined rau API 6D Class 600 specs, leak-tested ntawm 1.5 × ua hauj lwm siab
- Pump foundations: Sand-cam khwb cia hlau vaj tsev nrog kev sib txuas mounting lugs, kev ntxhov siab-relieved ua ntej zaum kawg milling
- Cobalt alloy nozzlesAMS 5387 khoom, as-cam khwb cia nto roughness Ra ≤ 3.2 µm, tsis muaj kev sib tsoo theem nrab
- Tsis yog-tus qauv winch shafts: T800 alloy, 100% ultrasonic soj ntsuam, qhov ruaj khov qhov tseeb tom qab 72-teev ib puag ncig ntub
Qee tus yuav sib cav tias kev nqis peev casting muab cov ntsiab lus zoo dua rau cov geometry nyuaj. But gravity die casting delivers superior mechanical properties—higher density, lower porosity, and repeatable tensile strength—critical when parts cycle between -20°C startup and 180°C operational temps. Peb tau ntsuas kev qaug zog lub neej kev txhim kho ntawm 37% hauv lub ntiajteb txawj nqus-tuag-cam khwb cia cobalt alloy valve lub cev piv rau kev nqis peev-cam khwb cia sib npaug nyob rau hauv zoo tib yam pulsating load profiles. Qhov txawv? Tswj kev taw qhia ua kom muaj zog thiab txo qis cov kab noj hniav nyob ze rau thaj chaw muaj kev ntxhov siab.
Kev cia siab rau kev xa khoom yog los ntawm kev qhuab qhia kev npaj-tsis yog cov lus cog tseg. Lawv cov kev ua haujlwm lean siv takt lub sijhawm ua haujlwm rau txhua tsev neeg ntawm qhov chaw: 18 teev rau cobalt alloy plug ntau lawm (xws li NDT), 32 teev rau stainless hlau twj tso kua mis vaj tse (nrog rau kev kho cua sov thiab kev soj ntsuam zaum kawg). Tus qauv coj lub sij hawm pib ntawm 12 hnub ua haujlwm - tsis yog hnub ua haujlwm - nrog rau kev tawm tswv yim txog kev tsim khoom hauv 48 teev ntawm kev xa daim duab. GD&T txhais tsis yog outsourced; lawv pab pawg metrology validates cov qauv datum tiv thaiv kev ua haujlwm sib dhos ua ntej tso tawm cov cuab yeej.
A Lub ntiajteb txawj nqus tuag casting Hoobkas khwv tau kev ntseeg siab los ntawm cov ntaub ntawv pov thawj-tsis yog daim ntawv qhia. Txhua qhov kev xa khoom muaj xws li daim ntawv pov thawj ntawm kev ua raws li cov khoom siv hluav taws xob cov khoom siv hluav taws xob, cov khoom siv hluav taws xob ntau, cov ntawv txheeb xyuas qhov ntev (CMM + optical comparator), thiab cov ntaub ntawv xeem tsis muaj kev puas tsuaj. Thaum lub twj tso kua mis nyob sab Europe xav tau tag nrho traceability rov qab mus rau ore keeb kwm rau ASME Tshooj VIII ua raws, QINGDAO QIANGSENYUAN muab cov khoom lag luam soj ntsuam cov ntsiab lus thiab cov ntawv xeem zeb tsis pub dhau 72 teev - tsis muaj kev thim rov qab, tsis muaj kev ncua.
Saib tom ntej, lawv R&D tsom mus rau cov txheej txheem hybrid: sib txuas lub ntiajteb txawj nqus tuag casting qhov kev ncaj ncees nrog lub zos CNC milling ntawm sealing nto uas xav tau sub-micron flatness. Cov ntawv pov thawj nthuav dav suav nrog AS9100 rau aerospace-qib cobalt Cheebtsam thiab ISO 13485 rau kev kho mob cov kua dej. Tab sis cov tub ntxhais tseem tsis hloov pauv - qhov tseeb cam khwb cia uas ua tau, tsis yog tuaj txog. Vim hais tias nyob rau hauv high-pressure hydraulics, offshore li qub, los yog hnyav-lub luag hauj lwm winch systems, qhov tseeb qhov tseeb tsis muaj kev ntseeg tau tsuas yog kim seem.
