Mainjiniya akamatchula zigawo za Alloy 4, makamaka papampu za hydraulic, ma valve othamanga kwambiri, kapena makina amafuta am'mphepete mwa nyanja ndi gasi - samangoyitanitsa magawo. Akubetcherana pa kukhazikika kwapang'onopang'ono panjinga yotentha, kukhulupirika kwa microstructural pambuyo pa chithandizo cha kutentha, ndi kusintha kwa zero batch-to-batch pakuyankha kwa cobalt-nickel alloy. Ichi ndichifukwa chake "fakitale ya Alloy 4" si mawu osakira wamba - ndi fyuluta. Ndipo ku Qingdao, malo amodzi amatsuka: QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.
Chifukwa Chake Alloy 4 Imafunikira Zambiri Kuposa Kungoponya Kapena Kuchimba
Aloyi 4 - yomwe nthawi zambiri imatchulidwa kuti AMS 5387 kapena T800-grade cobalt-based superalloy - sichimapangidwa ngati 304 zosapanga dzimbiri. Mlingo wake woumitsa ntchito umakwera pambuyo pa kusinthika kwa 10%. Kutentha kwake kumakhala pa ~12 W/m·K—kuchepera theka la aluminiyamu. Standard toolpaths chatter. Zozizira wamba zimasanduka nthunzi zisanadulire kutentha. Tawonapo masitolo akutaya 60% ya nyumba zoyambira zoyambira chifukwa adagwiritsa ntchito zoyikapo za carbide zomwe zidavotera Inconel 718, osati kukana kwamphamvu kwa AMS 5387.
Ndipamene kuphatikizika koyima kumafunikira-osati monga mawu otsatsa, koma monga kufunikira kwafizikiki. Ku QINGDAO QIANGSENYUAN, kuponyera, chithandizo cha kutentha, ndi ma CNC amitundu yambiri kumachitika pansi pa denga limodzi. Palibe handoffs zikutanthauza kuti palibe mipata ya mbiriyakale ya kutentha. Makasitomala akatumiza chojambula cha mphuno ya aloyi ya cobalt yokhala ndi ± 0.005 mm GD&T callouts pamalo otchinga mkati, gululo limatsimikizira kutulutsa kwambewu * isanatsanulidwe * ndikusintha machining strategy kutengera kuuma kwenikweni kwa kuponyedwa (osati masamba owerengeka). Izi zimachepetsa kuyambiranso kwa masabata mpaka maola.
Maluso Anayi Omwe Amatanthawuza Aloyi Yeniyeni 4 Kukonzekera
Sikuti sitolo iliyonse yazitsulo yolondola imagwira Alloy 4 modalirika. Izi ndi zomwe zimasiyanitsa kuthekera kotsimikiziridwa ndi zonena zamabulosha:
- Kufufuza kwazinthu mpaka kusungunuka kwambiri: Billet iliyonse ya T800 imakhala ndi malipoti oyesa mphero—carbon, cobalt, chromium, tungsten, ndi boron zomwe zimatsimikiziridwa motsutsana ndi ASTM B575. Palibe "zovomerezeka zofanana" m'malo.
- Kuyanjanitsa kutentha-mankhwala: Njira yothetsera vutoli pa 1175 ° C ± 5 ° C sikumayendetsedwa mu ng'anjo yosiyana. Imasanjidwa molunjika pambuyo pakupanga kwaukali, ndikuwongolera kuziziritsa komwe kumajambulidwa mpaka gawo lomaliza la geometry-yofunikira kuti tipewe kutsekeka kwa gawo la sigma pamapampu anyumba.
- Kumaliza kotsekedwa ndi CMM: Kulekerera komaliza kwa OD/ID panyumba za silinda zapampu za piston kumatsimikiziridwa pogwiritsa ntchito Zeiss CONTURA G2 CMMs—ndi ma probe olipidwa ndi kutentha omwe amawerengedwa tsiku lililonse. Osati "zitsanzo zoyesedwa." Chigawo chilichonse.
- Kutsimikizika kogwira ntchito mopitilira miyeso: Pulagi ya cobalt alloy sichimatulutsidwa mpaka itadutsa kuyesa kwa hydrostatic pressure pa 1.5 × ntchito yogwira ntchito kwa mphindi 30-palibe kutayikira, palibe kupunduka kwa pulasitiki. Kuyang'ana kowoneka bwino kwa ming'alu yaying'ono pansi pa 10 × magnification.
Kumene Operekera Ma Generic Akulephera—Ndi Momwe Kupha Mwamakonda Kumapambana
Ogula ena amaganiza kuti "Alloy 4 = njira yofanana ndi Hastelloy C-276." Zolakwika. Makina a Hastelloy okhala ndi zakudya zaukali; Aloyi 4 imafuna kutsika kwa RPM, kuwongolera kwa spindle kwamphamvu kwambiri komanso kuziziritsa kwa nayitrogeni wa cryogenic. Nthawi ina tinalandira oda yachangu ya AMS 5387 center shaft rollers ya injini yamagalimoto opangira makina - kasitomala adayesa mavenda atatu. Onse analephera pamwamba Ra <0.4 µm zofunika pambuyo popera. Kulakwa kwawo? Kugwiritsa ntchito mawilo a aluminiyamu. Njira yothetsera vutoli? Mawilo opangidwa ndi diamondi okhala ndi liwiro la 150 m / s ndi magudumu anthawi yeniyeni - amachitikira m'nyumba.
Izi sizongoyerekeza. Ndizobwerezabwereza. Kuyenda kowonda kwa QINGDAO QIANGSENYUAN kumapereka injiniya m'modzi kuchokera pakuwunikanso mawu kudzera pakubweretsa. Munthu ameneyo ali ndi matanthauzidwe a GD&T, akumawonetsa kusokoneza komwe kungachitike pakati pa ngodya ya mpando wa valavu ndi kuponya kojambula - zida zisanayambe. Palibe ma silo. Ayi, "si dipatimenti yathu." Njira imodzi yokha kuchokera ku sketch kupita ku gawo losindikizidwa.
Tanthauzo la “Kudalirika” M’ntchito—Osati Malonjezo
Kudalirika sikungonena za ISO 9001. Ndi za kupereka 127 cobalt alloy nozzles kwa North Sea subsea control module-panthawi yake, ndi ma cert athunthu, malipoti amtundu, ndi zipika zoyesa kukakamiza-ndikukhala ndi kasitomala kuyitanitsanso mkati mwa maola 48 chifukwa ziro mayunitsi amafunikira kusintha kwamunda.
Ikupanga maziko 210 a zitsulo zosapanga dzimbiri zopangira zitsulo zaku Southeast Asia zochotsa mchere m'madzi—iliyonse imakhala ndi ma weld prep grooves omata ± 0.15 mm—pamene ikusunga ≤2% zidutswa 18.
Ikuthandizira magulu a R&D okhala ndi mawonekedwe osinthika mwachangu: mawu a maola 72, nkhani yoyamba ya masiku 10, lipoti lathunthu la FAI-kuphatikiza magawo am'mbali azitsulo omwe akuwonetsa kutalika kwa manja kwa dendrite m'nyumba zopangira ndalama.
Ngati polojekiti yanu yotsatira ikuphatikiza Alloy 4-kapena AMS 5387, T800, kapena mtundu uliwonse wa cobalt-nickel womwe umafuna kuti ziro zigwirizane ndi magwiridwe antchito - kumanja Aloyi 4 fakitale sichidzangokwaniritsa zofunikira. Imayembekezera njira zolephereka zomwe simunapangebe. Ndiko kusiyana pakati pa wothandizira ndi mnzanu.
