Akatswiri opanga ma cobalt alloy akutulutsa, sikuti amangoyitanitsa zitsulo-amateteza chitetezo cha ntchito, kukana kuvala, komanso kukhazikika kwapang'onopang'ono, kutentha, kapena dzimbiri. Mpando umodzi wa valve wolakwika kapena nyumba yopindika ya pampu yopangidwa kuchokera ku AMS 5387 cobalt alloy imatha kuyambitsa kulephera kwa ma hydraulic system kapena zida zamafuta. Ndicho chifukwa chake kufufuza kuchokera ku a fakitale ya cobalt alloy kuponyera magawo ndi kutsimikiziridwa zitsulo chilango-osati kuponya mphamvu-sikukambirana.
Kuponyedwa kwa cobalt kwenikweni kumafuna zambiri kuposa kutentha ndi mchenga
Tawona ma projekiti ambiri akuyimitsidwa chifukwa ogulitsa adagwiritsa ntchito ma aloyi a cobalt ngati chitsulo chokhazikika. Ma superalloys opangidwa ndi Cobalt-makamaka T800 ndi AMS 5387 magiredi-amachepa mosayembekezereka panthawi yolimba, amakana makina atatha kuponyera, ndikupanga microsegregation ngati kuzizira sikuyendetsedwa mwamphamvu. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Kuponyedwa kulikonse kwa cobalt kumayamba ndi kutsimikizika kwazinthu zopangira: kutentha kulikonse kumakhala ndi malipoti owoneka bwino, kutsimikizira kukula kwambewu, ndi zolemba zakale zamafuta. Palibe gulu lomwe limalowa m'ng'anjo yamoto popanda kufanana ndi mankhwala ake ndi ASTM F75 kapena AMS 5710 - mpaka ± 0.02% pa chromium ndi ± 0.01% pa carbon.
Malo athu amagwiritsa ntchito zopangira zopangira ma nozzles ndi mapulagi omwe amafunikira ma radii olimba ndi kumaliza pamwamba pa Ra 1.6 µm—ndi kuponyera mchenga wobiriwira kuzinthu zazikulu, zodzaza mwamapangidwe monga ma silinda a pampu ya piston. Chofunika kwambiri, timaphatikiza njira ya post-cast annealing * in-house*, kupewa kuchedwa kwa kutentha kwa gulu lachitatu komwe kungapangitse kuti mbewu zisawonongeke kapena kupanga gawo la sigma. Wokasitomala wina waku North America adachepetsa kulephera kwa magawo ndi 73% atasintha kuchoka kwa ogulitsa akunyanja kupita ku magawo athu apampu a AMS 5387 —chifukwa tidakhala ndi masitayilo apakati mkati mwa 25–35 µm, osati 50+ µm yodziwika pamayendedwe amtundu uliwonse.
Kuphatikizika koyima sikungolankhula - ndi inshuwaransi yayikulu
Mafakitale ena amaponya mbali za cobalt. Ena amawapanga makina. Ochepa amachita zonse ziwiri—pamene amayang'anira chithandizo cha kutentha, kutsimikizira kwa GD&T, ndi kukhulupirika kwapamtunda kudutsa kachitidwe kamodzi. Mpata umenewo ndipamene kulolerana kwachulukira kumachitika. Tayesa zopatuka zochulukirapo mpaka ± 0.12 mm pazibowo zovuta kwambiri pamene kuponyera ndi makina kumachitika pamalo osiyana-ngakhale ndi zojambula "zolimba" ± 0.05 mm.
Pamalo athu ovomerezeka a ISO 9001 ku Qingdao, mphuno ya aloyi ya cobalt imasuntha kuchoka papatani ya sera kupita kukuyendera komaliza kwa CMM popanda kusiya malo opangira. Malo athu a 5-axis CNC amakhala ndi malo obwerezabwereza a ± 0.003 mm pa malo olimba a T800; zofananira zowoneka bwino zimatsimikizira kulolerana kwambiri pazigawo zokhala ndi mipanda yopyapyala mpaka makulidwe a khoma la 0.3 mm. Kwa ma roller a winch center shaft omwe amagwiritsidwa ntchito pamagalimoto a engineering, timaphatikiza kuponyera kwa centrifugal (kwa kachulukidwe ka yunifolomu) ndikutembenuza molimba m'malo mogaya-kuchotsa kuwonongeka kwapansi pomwe tikupeza HRC 42-46 kuuma kwapamwamba ndi 0.005 mm kuthamanga.
Izi sizongoyerekeza. Pamene pompu yaku Southeast Asia OEM imafunikira mapulagi a cobalt alloy osakhazikika okhala ndi ma asymmetric sealing geometry ndi njira zoziziritsira zophatikizika, tidapereka ma prototypes ogwira ntchito m'masiku 11 ogwira ntchito - osati masabata - pogwiritsanso ntchito zida za AMS 5387 zam'mbuyo ndikutsimikizira njira zoyendera ndi mphamvu zamadzimadzi musanathire.
Kuwongolera khalidwe komwe kumayankha mafunso enieni-osati mndandanda wazinthu zokha
"Kuyendera kodutsa" sikukutanthauza kanthu pokhapokha mutadziwa * zomwe * zidayang'aniridwa, *motani *, ndi * motsutsana ndi chiyani *. Sitidalira macheke omaliza okha. Ingots ya cobalt yomwe ikubwera imayang'aniridwa ndi spark emission spectroscopy ndi kuyesa kwa ultrasonic kwa voids mkati. Panthawi yoponya, ma thermocouples amawunika zolimbitsa thupi munthawi yeniyeni. Pambuyo popanga makina, gulu lililonse la valve yokakamiza limayesedwa ndi hydrostatic pa 1.5 × ovotera kukakamiza kogwira ntchito - kuphatikiza kuyang'ana kolowera kwa utoto pamadera onse okonzedwanso.
Chofunika koposa, timasunga kutsatiridwa kwathunthu: nambala zambiri, chipika chosungunuka, piritsi la kutentha, ID ya lipoti la CMM, ndi siginecha ya opareshoni zimaphatikizidwa muzolemba za digito za gawo lililonse. Makasitomala amapeza izi kudzera pa portal yotetezeka-osati ngati ma PDF, koma monga data yosakira, yosindikizidwa nthawi. Mmodzi wa ophatikiza ma hydraulic system ku Europe adadula nthawi yawo yoyendera ndi 65% atatengera njira yathu yotsatsira magawo a aloyi a cobalt.
Timalengezanso zoopsa zomwe zingapangidwe msanga, osati monga ma redlines, koma ngati njira zina zomwe zingatheke. Ngati kujambula kumafuna utali wa 0.2 mm paphewa la pulagi ya T800, tidzapereka utali wa 0.3 mm wokhala ndi ntchito yosindikiza yofanana ndi 40% moyo wautali wa zida. Palibe mawu. Palibe kuchedwa. Ma tradeoffs okha opangidwa ndi physics.
Chifukwa chiyani kuponyera kolondola kwa cobalt kukadali kofunikira-mu 2024 ndi kupitirira
Ma alloys a cobalt sizinthu zoyambira. Akuthandizira kugwiritsa ntchito m'badwo wotsatira: mapampu opopera mafuta a hydrogen, makina oyendetsa magetsi oyenda pansi pa nyanja, ndi ma compact hydraulic motors amagalimoto odziyimira pawokha. Izi zimafuna chilolezo cholimba, kukana kutopa kwambiri, komanso kusalekerera ma microcracks —mikhalidwe yomwe cobalt imaposa faifi tambala kapena chitsulo chosapanga dzimbiri.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imayang'ana kwambiri pazigawo zogwirira ntchito zamafakitale-osati zokongoletsera zokongoletsera kapena mabatani otsika kwambiri. Kuganizira kumeneku kumanola chidziwitso chathu: momwe kufalikira kwamafuta a cobalt kumayenderana ndi mipando ya valavu yachitsulo, momwe kupanikizika kotsalira kumakhudzira kuzungulira pambuyo pa kutentha kwapang'onopang'ono, momwe kutsirizira kwapansi kumakhudzira kukokoloka kwa cavitation mu maziko a pampu. Sitigulitsa magawo a cobalt. Timapereka maenvulopu otsimikiziridwa - okhala ndi data kumbuyo kwazinthu zilizonse.
Ngati ntchito yanu ikuphatikizapo kupanikizika pamwamba pa 350 bar, kutentha kupitirira 400 ° C, kapena zowononga ngati mafuta odzaza mchenga, yambani ndi kubwereza zinthu-osati pempho la mawu. Funsani za malipoti a solidification modelling, zotsatira za mayeso a intergranular corrosion pa ASTM G28, komanso ngati fakitale ya cobalt alloy kuponyera magawo ali ndi chitsimikizo cha kusintha kwa kutentha. Wokondedwa woyenera sangangokumana ndi kusindikiza kwanu. Adzakuthandizani kukhala ndi malire pakati pa kulephera ndi ntchito.
