Mainjiniya akamatchula za ASTM A747, samangosankha zinthu - akudzipereka kuti agwire ntchito. Muyezo uwu umayang'anira ma cobalt-chromium-nickel alloys opangidwira kuvala kwambiri, dzimbiri, komanso kukana kutentha, makamaka pazigawo zapampu zozungulira, matupi othamanga kwambiri, ndi ma hydraulic system housings komwe kulephera sikungatheke. Koma kupezerapo mwayi kwa ASTM A747 sikungofuna kupeza * chilichonse. Ndizokhudza kuyanjana ndi wothandizira yemwe amawona kusasinthasintha kwazitsulo ngati sikungakambirane, yemwe amatsimikizira kutentha kulikonse motsutsana ndi malire a mankhwala a AMS 5387, komanso yemwe amawongolera unyolo wonse: kuchokera ku T800-grade yaiwisi ya billet mpaka kuwunika komaliza kwa GD&T pa CMM yokhazikika.
Chifukwa chiyani ofufuza a "ASTM A747" nthawi zambiri amafika kumapeto
Tawunikanso ma RFQ opitilira 200 ochokera ku North America pump OEMs ndi operekera mafuta aku Europe m'miyezi 18 yapitayi. Ambiri amayamba ndi funso limodzi lofulumira: "Kodi mutha kuponya ASTM A747-ndikutsimikizira?" Ogulitsa ambiri amayankha kuti "inde" kenako amayimilira pa certification. Amachepetsa kusungunuka, kulumpha kuyesa kwa dzimbiri pa ASTM A262 Practice E, kapena satha kupereka malipoti atsatanetsatane atsatanetsatane. Tawona magulu akuponyedwa akukanidwa - osati chifukwa cholakwa - koma chifukwa chromium idatsika ndi 0.3% pansi pa 28-32% yofunikira ndi ASTM A747. Kusiyana kumeneko sikuwonekera pajambula. Zimawoneka ngati kuponyedwa msanga mu gasi wowawasa.
Vuto lenileni si luso loponya. Ndi kuphatikiza koyima. Kutsatira koona kwa ASTM A747 kumafuna kuwongolera magawo anayi olumikizidwa: kudya kwazinthu zovomerezeka, vacuum-arc remelted (VAR) kapena kuthira kosungunula, kuyika njira ndi zipika zanthawi yonyowa / kutentha, komanso kutsimikizira kwapang'onopang'ono kwapambuyo kutentha. Popanda chiwongolero chimenecho, "ASTM A747 fakitale" imakhala chilankhulo chotsatsa, osati zenizeni zopanga.
Kumene kuyimitsa kolondola kumakwaniritsa kutsimikizika kogwira ntchito
Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ASTM A747 si mndandanda wazinthu. Ndilo maziko a gawo lathu la ntchito yapampu. Mizere yathu yoponyera mchenga imatsanulira kutentha pansi pa nsabwe za argon. Gulu lililonse limawunikiridwa musanathire - komanso pambuyo pa chithandizo cha kutentha. Timasunga kutsata kwathunthu: nambala yosungunuka, curve ya kutentha kwa ladle, data ya kuzizira, ndi kuuma kwa Rockwell C kudutsa magawo atatu aliwonse. Pamagawo ogwirizana ndi AMS 5387, monga ma nozzles a cobalt aloyi pamapampu obwereza, timawonjezera kutsimikizira kukula kwambewu ya ASTM E112 ndi kuyesa kwa dzimbiri kwa ASTM A262 Practice E intergranular corrosion pa zitsanzo za mboni.
Lamuloli limafunikira kwambiri pazigawo zomwe zimakhudzidwa ndi geometry. Tengani nyumba za silinda pampu ya pistoni: makulidwe a khoma pamwamba pa ± 0.15 mm kumayambitsa kufalikira kwamafuta osagwirizana, zomwe zimatsogolera kugwidwa ndi katundu. Njira yathu imaphatikiza kulondola kwa kachitidwe ka ndalama ndi mabokosi oyambira opangidwa ndi CNC-kenako amatsimikizira ziboliboli zovuta zokhala ndi mpweya komanso kumalizidwa kwapamwamba ndi profilometry. Chotsatira? Ma cylinders okhala ndi nyumba <0.005 mm kuzungulira kutalika kwa 300 mm, ngakhale muzojambula za ASTM A747 zochokera ku T800.
Zinayi zosakambidwa pazantchito zofunika kwambiri za ASTM A747
- Zopangira zopangira: Timangopeza ma billets a VAR oyengedwa a cobalt-nickel okhala ndi malipoti oyesa mphero okhudza C, Cr, Ni, Mo, Fe, Si, Mn, ndi N - otsimikiziridwa motsutsana ndi ASTM A747 Table 1 kulolerana asanavomerezedwe.
- Zolemba za chithandizo cha kutentha: Kuzungulira konse kwa ng'anjo kumayikidwa - nthawi yonyowa, kuchuluka kwa mafunde, mame am'mlengalenga, ndi kuzimitsa kutentha kwapakati - ndi siginecha ya digito yomwe imatha kutsatiridwa ndi ogwiritsa ntchito ndikusintha
- M'ntchito za metrology: Miyeso yovuta imayezedwa pakati pa ndondomeko pogwiritsa ntchito Zeiss CONTURA G2 CMMs; kukhulupirika kwapadziko lapansi kumatsimikiziridwa kudzera mu kujambula kwa SEM pamabala a zitsanzo
- Kuyika koyeserera kogwira ntchito: Misonkhano yomaliza imayesedwa kukakamiza pa API 598, ndi mitengo yotayikira yojambulidwa - osati kungodutsa / kulephera - motsutsana ndi zomwe kasitomala amatchulidwa.
Izi sizongoyerekeza. Kota yatha, tidapereka ma roller 42 a ASTM A747 apakati pa ma winch system. Chigawo chilichonse chinali ndi kuwunika kokwanira kwa kutentha, kulimba kwamphamvu> 1000 MPa, ndi kulimba kwamphamvu> 35 J pa -20°C—zonse zimatsimikiziridwa ndi ASTM E23. Wothandizirayo adanenanso kuti palibe vuto lililonse m'miyezi 18 yogwira ntchito m'malo odzaza mchere.
Kufikira kwachindunji, osati zigawo zogawa
Ntchito za ASTM A747 zimafuna kukambirana kwaumisiri-osati mafomu oyitanitsa. Wopanga ma valve wa ku Germany atatipempha kuti titsimikizire za geometry yowongoleredwa, gulu lathu lidayesa kupsinjika kwamafuta * tisanagwiritse ntchito zida, kulengeza malo omwe atha kukhala otentha pamphambano ya doko la 3 koloko, ndipo adaganiza zosintha kuzizira kwanuko. Kugwirizana kumeneku kunadula nthawi yawo yotsogolera ndi masiku 22. Timagwiritsa ntchito kutanthauzira kwa GD&T, kutsimikizira kujambula, ndi mayankho opangira - osati monga zowonjezera, koma monga masitepe okhazikika.
Malo athu ovomerezeka a ISO 9001 ku Qingdao amagwira ntchito mwachindunji ndi B2B kokha. Palibe ogawa. Palibe anthu apakati. Mumalankhula ndi mainjiniya omwe amakonza CNC lathe kudula pulagi yanu ya ASTM A747, osati wobwereketsa omwe akugwira mawu pamabuku a PDF. Nthawi zotsogola zimakhazikitsidwa panthawi ya mawu: masabata a 12 kuti avomereze nkhani yoyamba, masabata a 8 obwerezabwereza - otsekedwa molembedwa, ndi zilango zochedwa.
Mgwirizano wa fakitale wa ASTM A747 umayenda bwino pamene zitsulo, makina, ndi kuyankha zimakumana. Ngati dongosolo lanu lotsatira likufuna kukhulupirika kwa cobalt-alloy-osati pepala lokhalokha-yambani ndi kufufuza zinthu, tsimikizirani mbiri ya kutentha kwa kutentha, ndikutsimikizira kuti ndani asaine lipoti lomaliza la CMM. Kusiyana pakati pa kutsata kwatsatanetsatane ndi kudalirika kwamunda kumakhala mwatsatanetsatane. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amapanga kusiyana kumeneko mu kutsanulira kulikonse.
