Kugadzira yemhando yepamusoro simbi poda ndiyo yekutanga nhanho yakakosha mune chero hupfu simbi fekitori-uye iyo isina kusimba chinongedzo mucheni inogona kukanganisa maitiro ese ekudzika. KuQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., takagadzira anopfuura 12,000 kg yecobalt-nickel uye simbi isina tsvina pamitumbi ye hydraulic valve, pombi dzimba, uye AMS 5387-inopindirana nozzles kubvira 2021. kukundikana muT800 alloy zvikamu; unyoro hwemukati pamusoro pe 0.08% yakakonzeresa kupindika kwepamusoro panguva inopisa isostatic kudzvanya; uye unverified supplier batch traceability yakanonoka kutariswa kwevatengi katatu. Kugadzirwa kwehupfu hwepasirese kunoda zvinopfuura midziyo-inoda chirango chesimbi, mapuroteni anodzokororwa, uye zero kushivirira pakusiyana.
Atomization: Iko Chemistry Inosangana neKinematics
Gasi atomization inoramba iri yedu yekuenda-kune nzira yecobalt-based alloys seT800 uye AMS 5387-kunyanya kana dimensional kugadzikana pasi pe200 MPa hydraulic mitoro isingagone kutaurirana. Isu tinoshandisa nitrogen pa7.2 MPa pressure uye 45° melt-stream impingement angle kuti tiwane D.50 = 28–32 μm ne <5% oversize (>106 μm) zvimedu. Atomization yemvura inoshanda kune zvimiro zvesimbi hupfu (semuenzaniso, SS316L yepombi nheyo), asi chete mushure mekupedzisira-atomization annealing pa950 ° C muhydrogen kuderedza okisijeni pasi pe0.15 wt%. Zvine hutsinye, isu hatife takasvetukira ultrasonic dispersion bvunzo tisati tasevha: kana zvimedu zvikaitazve agglomerate mukati me90 seconds mu isopropyl alcohol, isu tinoramba iyo mijenya-kunyangwe kana sieve ongororo ikapfuura. Imhaka yekuti maagglomerates anotsemuka zvisingafungidzike panguva yekutsikitsira, achigadzira density gradients anotanga madiki madiki panguva yekupisa.
Rotary Electrode Maitiro: Paunenge Usingakwanisi Kutenga Oxides
Kune cobalt-nickel nozzles inoshanda pamusoro pe650 ° C mumafuta uye gasi downhole maturusi, oxide inclusions injodzi. Pano, rotary electrode processing (REP) inopa izvo gasi atomization isingagone: pedyo-zero okisijeni (<0.02 wt%), spherical morphology, uye yakasimba saizi kutonga (D10–D90 span <1.8). Isu tinoruka AMS 5387 maelectrodes pa12,500 rpm mukati mevacuum chambers inobatwa pa1 × 10.−2 mbar. Iyo poda inoguma inoyerera pa22 s/50g (Hall Flowmeter), inotakura kusvika ku62% inooneka density, uye sinter ku> 99.2% theoretical density pasina HIP. Asi REP haisi yepasirese-isu tinoidzivirira kune simbi yekukanda inoda graphite nucleation nzvimbo. Pane kudaro, tinoshandisa mvura-atomized Fe-2.5C powder ine controlled kabhoni segregation, wobva wawedzera 0.8% flake graphite panguva yekusanganiswa kuti tive nechokwadi cheuniform graphite nodules mushure me sinter-anneal.
Magedhi Emhando: Hapana Hupfu Inosiya Pasina Kupfuura Zvese zvina
Isu tinomanikidza mana asingagone kutaurirana ekutarisa pamberi pechero batch yehupfu yaenda kusanganisa:
- Kemikari verification: ICP-OES inopesana neyakavimbiswa zvinyorwa (CRM NIST SRM 1262a yeCo, CRM NIST SRM 3125a yeNi); kutsauka> 0.15% inokonzeresa ongororo yakazara
- Particle size & chimiro: Laser diffraction (Malvern Mastersizer 3000) + SEM imaging; chikamu chechiyero> 1.8 kana kutenderera <0.7 haikodzeri
- Flow & density: Hall Flowmeter + Scott Volumeter; kuyerera kunofanirwa kunge kuri 18–24 s/50g, kuwanda kwehuwandu 2.8–3.1 g/cm³
- Contamination screening: Ferrography yemarara anopfeka ferrous; XRF scan yeCr, Mo, kana Ti inoteedzera kubva kumitambo yapfuura
Isu tinoisa mhedzisiro yese mune yedu ISO 9001-yakasimbiswa MES system-ine yakazara zvinhu traceability kudzokera kune mbishi ingot kupisa nhamba. Kana batch ikatadza kunyangwe gedhi rimwe chete, rinogadziriswa-kwete kuderedzwa.
Nei “Kushanda” Kunoreva Kudzorwa Kusiyanisa, Kwete Kumhanya
Mamwe mafekitari anodzinga matani paawa. Isu tinodzingirira kutsauka kwemaitiro. Mukugadzira kwedu hupfu muhupfu metallurgy fekitori mashandiro, kushanda zvakanaka kunoreva kubata D50 kusiyana kusvika ± 0.9 μm kumativi gumi akatevedzana-kwete kucheka nguva yeatomization ne12%. Sei? Nekuti piston pombi silinda dzimba dzakagadzirwa kubva paupfu ne ± 3.2 μm D50 mutsauko wakaratidza 22% yepamusoro yekudonha mazinga mukumanikidza kuyedzwa pa350 bar. Isu tinodyara mune chaiyo-nguva plasma tembiricha yekutarisa, yakavharwa-loop gasi kudzvanywa, uye otomatiki sieve shaker calibration maawa mana oga oga. Iyo ROI haisi kukurumidza kubuda-kubvisa rework pamadhora mazana mana nemazana maviri emadhora cobalt alloy valve zvigaro.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inobata hupfu kwete seyakabikwa asi seyekutanga DNA yechinhu chose. Yedu yekugadzira poda mupoda metallurgy fekitori kuyerera kunotanga ne alloy chemistry kusimbiswa, inoenderera kuburikidza ne kinematically optimized atomization, uye inopera chete mushure mana akazvimirira emhando magedhi anosimbisa kudzokorora-kwete kamwe chete, asi kuyambuka yega yega kilogiramu mujeti. Ndiwo mavharuvhu ekumanikidza anopona 15,000-awa yehupenyu hwesevhisi mumapombi epasi pegungwa. Ndiwo magadzirirwo anoita winch centre shaft rollers inochengetedza kubuda pasi pe8 μm mushure memazana mashanu ekudziya kwemhepo. Ramangwana nderevagadziri vehupfu vanoyera kubudirira kwete mumakirogiramu pashift—asi mumamicrostructures pamicrometer.
