Apo mainjiniya anotsanangura simbi yakakanda mari yekukandira mugadziri fekitori mhinduro, havasi kungotenga zvikamu-vari kuchengetedza kugadzikana pasi pemhepo inopisa, microstructural consistency mhiri kwe500-unit batches, uye zero kushivirira kweporosity mumiviri yevharuvhu yekumanikidza. Isu takaona mapurojekiti akawandisa akanonoka nevatengesi vanobata kukanda mari senge-saizi-inokodzera-ese maitiro-kunyanya ane grey uye ductile cast irons, uko kabhoni yakaenzana kutonga, mold preheat ramp rates, uye dova poindi mukuvaka-makoko zvinoraira machinability uye kuneta hupenyu.
Sei Kukandira Iron Kunoda Zvakawanda Kupfuura Kungowanikwa
Simbi yekukanda haisi "nyore kukanda" nekuda kwekuti inoyerera zvakanaka. Yayo graphite morphology - maflakes mune grey iron, nodules mu ductile - inopindura zvakanyanya kutonhora mwero, inoculation nguva, uye kunyange ambient humidity panguva yekusangana kwewakisi. Panzvimbo yedu inowirirana neISO muQingdao, tinobata mijenya yega yega seyeyedzero yesimbi: zvitupa zvakagadziridzwa zvisati zvasanganiswa, choto chinonyungudika ichiteverwa nechaiyo-nguva spectrometry, uye magoko akabikwa pa1,100 ° C nenguva yekugara kwemaminetsi makumi matatu - kwete nekuti chiyero chinotaura kudaro, asi nekuti isu tinoderedza kudzoreredzwa kweiyo 2%. 1,050°C kwe>25 maminetsi.
Takaendesa pamusoro pe470 pressure valve housings ye hydraulic systems inoshanda pa420 bar-hapana yakakundikana mubasa. Sei? Nekuti isu hatimire paASTM A536 kana GB/T 1348. Isu tinosimbisa nodularity kuburikidza nekuongorora kwemifananidzo pane yega yega yechitatu kukanda, mhanyisa mabhawa ekutena kubva pakudururwa kwakafanana sechikamu chekugadzira, uye mepu kuomarara gradients mhiri kwecylinder edzimba madziro tichishandisa 12-point Rockwell C scans. Ndiwo mabatiro aunobata nzvimbo inotonhorera inoshandura madziro e30-mm kuita brittle interface.
Iko Investment Casting Inorova Jecha-uye Kana Isingaite
Kukandira kwekudyara kunoburitsa ± 0.05 mm mutsara kushivirira uye Ra 1.6 µm se-yakakandwa pamusoro pekupedzisira-yakakosha kune piston pombi silinda dzimba uko chisimbiso groove geometry inoraira mazinga ekudonha. Asi isu tinoudza vatengi kumberi: kana chikamu chako chinorema kupfuura 45 kg kana iine ndima yemukati yakafara kupfuura 8 mm, kukanda jecha kunowanzo kupa kugadzikana kwepakati uye kuderera kwemutengo pakirogiramu. Isu takafamba kubva pane zvinyorwa apo jecha raizounza kusimba kwemadziro-kusimba-nekuti kutendeseka kunodzivirira kutadza kwemunda.
Yedu hybrid workflow inovhara mukaha. Semuenzaniso: winch centre shaft rollers inotanga sekudyara-cast ductile iron (ASTM A), yobva yapinda CNC ichibatidza 5-axis lathes kune echokwadi majenari mukati me 0.015 mm TIR. Kurapa kwekupisa kunotevera-kudzima pa890 ° C, kupisa pa620 ° C - ndokupfura peening kuti iite +280 MPa pamusoro pekumanikidza kudzvinyirira. Zvakaguma nei? Shaft hupenyu hwakawedzerwa 3.7 × muoffshore engineering mota kunyorera uko munyu-wakaremerwa grit inomhanyisa pitting.
Zvina Zvisina Kukurukurirana mune Yepamusoro-Kuitwa Cast Iron Production
Chero simbi yakakanda mari yekukandira mugadziri fekitori vachiti kuvimbika kunofanira kuratidza izvi zvina zvinodzora:
- Material traceability kusvika pakupisa nhamba-kwete chete mill certs, asi spectral retest mishumo yeSi, Mn, P, S, uye yakasara Cu/Ni/Cr mubatch yega yega;
- Shell kutendeseka verification-isu tinoshandisa helium leak yekuyedza pane yakakosha hollow castings, kwete kungoona yekutarisa;
- In-process dimensional gedhi-CMM inotarisa mushure mekuita de-waxing, mushure mekupfura, uye post-pfuti-kuputika-machining asati atanga;
- Kushanda kusimbiswa pane bvunzo zvigadziriso-Miviri yevhavha inoyerera-yakaedzwa pa 1.5 × rated pressure; pombi dzimba dzinotenderera-yakaenzana kusvika kuG2.5 giredhi.
Isu tinoramba 8.3% yekutanga-chinyorwa castings-kwete yekukanganisa kwekuzora, asi nekuti GD&T callouts paflange inokwirisa nzvimbo yakapfuura 0.03 mm kushivirira kwekureruka. Chirango icho chinoenda kusvika pakati-vhoriyamu inomhanya: yedu yakaonda kuronga sisitimu inogovera buffer nguva yegoko-yakaoma-kutenderera kugadziridzwa kana monsoon humidity spikes pamusoro pe75% RH. Nekuti kukanda hakusi kwemamiriro ekunze akakwana - ndezvekudzora zvimiro zvaunogona kuyera.
Zvinodiwa Nemainjiniya—Kwete Zvinovimbiswa Nemabhurocha
Iwe unoda kujekeswa pane yekutungamira nguva yekutengeserana-offs: kuisa mari kunowedzera 2-3 mavhiki ekushandisa uye goko rekuvaka, asi kunobvisa chipiri machining pa68% yezvinhu mune yedu yakajairwa pombi nheyo dhizaini. Unoda kujeka pakuenderana kwecobalt-alloy-isu tinogara tichikandira AMS 5387 padivi pe ductile iron mumagating masisitimu akagovaniswa, asi mushure mekuona kusawirirana kwekuwedzera kwemafuta kuburikidza neinogumira-element simulation yekusimbisa kumberi. Unoda mumwe munhu anozoratidza kusawirirana kweGD&T nekukurumidza: takabata 0.02 mm kushivirira pane 12-mm dowel gomba iyo yaida kutamisa chirongwa chese chedhamu - kuchengetedza madhora makumi maviri nemana mumakanda akaraswa.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. haitengesi macastings. Isu tinogadzirisa maitiro ekutadza maitiro-anovuza nzira, kupisa kwemafuta, abrasive kupfeka-nekubatanidza simbi, process fizikisi, uye mechanic dhizaini chinangwa. Simba redu riri mukuita zvinhu zvishoma, asi kuzviita nekudzokororwa kwakanyorwa: kubva kuT800 cobalt nozzles inobata 650 ° C yakanyungudutswa slag kusvika kukanda-simbi pombi mabhesi anorarama makore gumi nemashanu ekuendeswa kunze kwemahombekombe pasina kushatisa.
Kana yako inotevera purojekiti inoda simbi yakakanda mari yekukandira mugadziri fekitori kugona kwakadzika midzi muchiyero-kwete kushambadzira-tanga nekudhirowa wongororo. Isu tichakuudza izvo zvinogadzirwa, izvo zvinoda kugadziriswa, uye chaizvo panogara njodzi. Kwete nemashoko asina kujeka. Mune microns, megapascals, uye zvinhu zvekupisa nhamba.
