Lapho onjiniyela becacisa izingxenye ze-Alloy 4—ikakhulukazi amaphampu asebenzisa amanzi amaningi, amavalvu okucindezela okukhulu, noma amasistimu kawoyela negesi asogwini—abagcini ngoku-oda izingxenye. Babhejela ukuzinza kwe-dimensional ngaphansi kwebhayisikili eshisayo, ubuqotho be-microstructural ngemva kokwelashwa kokushisa, kanye nokwehluka kwe-batch-to-batch okuyiziro ekuphenduleni kwengxube ye-cobalt-nickel. Yingakho i-"Alloy 4 factory" ingelona igama lokusesha elijwayelekile—iyisihlungi. Futhi e-Qingdao, indawo eyodwa iyisusa njalo: QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.
Kungani i-alloy 4 idinga okungaphezu kokukhipha noma ukwenza imishini
I-alloy 4-evame ukubhekwa njenge-AMS 5387 noma i-T800-grade cobalt-based superalloy-ayenziwe njengomshini we-304 engagqwali. Izinga layo lokuqinisa umsebenzi liyakhuphuka ngemuva kokuguqulwa okungu-10%. I-thermal conductivity yayo ihlala kokuthi ~12 W/m·K—ngaphansi kwengxenye ye-aluminium. Izindlela zamathuluzi ezijwayelekile ziyaxoxa. Izipholisa ezivamile ziyahwamuka ngaphambi kokusika ukushisa kuhlakazeke. Sibone izitolo zilahla u-60% wezindlu zamasilinda eziqalwe kuqala ngoba zisebenzisa okufakwayo kwe-carbide okulinganiselwe ku-Inconel 718, hhayi ukumelana nokugqokwa okuphezulu kwe-AMS 5387.
Kulapho ukuhlanganiswa okuqondile kubaluleke khona—hhayi njenge-jargon yokuthengisa, kodwa njengesidingo sefiziksi. E-QINGDAO QIANGSENYUAN, ukusakaza, ukwelashwa kokushisa, kanye ne-CNC ye-multi-eksisi kwenzeka ngaphansi kophahla olulodwa. Awekho ama-handoffs asho ukuthi awekho amagebe omlando oshisayo. Uma iklayenti lithumela umdwebo womlomo we-cobalt alloy ±0.005 mm GD&T callouts endaweni ye-taper yangaphakathi, ithimba liqinisekisa ukugeleza kokusanhlamvu okubalulekile *ngaphambi* kokuthululwa—futhi lilungisa isu lomshini ngokusekelwe kubunzima bangempela bokusakazwa (hhayi izilinganiso zeshidi elicacisiwe). Lokhu kunciphisa ukusebenza kabusha kusuka emavikini kuya emahoreni.
Amakhono Amane Achaza I-Real Alloy 4 Ukulungela
Akuzona zonke izitolo zensimbi ezinembayo eziphatha i-Alloy 4 ngokwethembeka. Nakhu okuhlukanisa amandla afakazelwe ezimangalweni zezincwajana:
- Ukulandelela okubalulekile phansi kuze kuncibilike kakhulu: Yonke i-billet ye-T800 iphethe imibiko yokuhlola egcwele yokugaya—ikhabhoni, i-cobalt, i-chromium, i-tungsten, nokuqukethwe kwe-boron okuqinisekiswe ngokumelene ne-ASTM B575. Akukho okushintshiwe "okulingana okuqinisekisiwe".
- Ukuvumelanisa ukwelashwa kokushisa: Ukufakwa kwesixazululo kokuthi 1175°C ±5°C akusebenzi esithandweni somlilo esihlukile ngaphandle kwesayithi. Ilandelana ngokuqondile ngemva komshini onzima, ngamanani okupholisa alawulwayo afakwe kumephu engxenyeni yokugcina yejiyomethri—okubalulekile ukugwema ukumbozwa kwesigaba se-sigma kumaflange ezindlu zephampu.
- Ukuqedela okukhiyiwe kwe-CMM: Ukubekezelelwa kokugcina kwe-OD/ID ezindlini zesilinda sephampu ye-piston kuqinisekiswa kusetshenziswa ama-Zeiss CONTURA G2 CMMs—ama-probe anxeshezelwa ngezinga lokushisa alinganiswa nsuku zonke. Hhayi “isampula elihloliwe.” Wonke amayunithi.
- Ukuqinisekisa okusebenzayo ngaphezu kobukhulu: Ipulaki ye-cobalt alloy ayikhishwa kuze kube yilapho idlula ukuhlolwa kwengcindezi ye-hydrostatic ku-1.5 × ingcindezi yokusebenza imizuzu engu-30-akukho ukuvuza, akukho deformation yepulasitiki. Ukuhlola okubonakalayo kuhlola imifantu emincane ngaphansi kokukhulisa okungu-10×.
Lapho Abahlinzeki Bezinto Ezijwayelekile Behluleka—Futhi Ukufezwa Ngokwezifiso Kuphumelela Kanjani
Abanye abathengi bacabanga ukuthi “I-Alloy 4 = inqubo efanayo ne-Hastelloy C-276.” Akulungile. Imishini ye-Hastelloy enezifunzo ezinolaka; I-alloy 4 idinga i-low-RPM, isilawuli sokuphotha se-torque ephezulu kanye nokupholisa i-nitrogen ye-cryogenic. Sake sathola i-oda lokushesha lama-AMS 5387 center shaft roller for iwinch yemoto yobunjiniyela—iklayenti lalizame abathengisi abathathu. Konke kuhlulekile ekuqedeni u-Ra <0.4 µm imfuneko ngemva kokugaya. Iphutha labo? Ukusebenzisa amasondo e-alumina. Isixazululo? Amasondo e-vitrified anedayimane anesivinini esingu-150 m/s nokugqokwa kwamasondo ngesikhathi sangempela—kwenziwa endlini.
Lokhu akulona ithiyori. Kuyaphinda. Ukugeleza komsebenzi okunciphile kwe-QINGDAO QIANGSENYUAN kwabela unjiniyela oyedwa kusukela ekubuyekezweni kwamaphuzu ngokulethwa. Lowo muntu ungumnikazi wokuhumusha kwe-GD&T, ukumaka ukuphazamiseka okungaba khona phakathi kwe-engeli yesihlalo sevalvu nokusalungiswa kokusakaza—ngaphambi kokuthi kuqale ukusebenza. Azikho izisele. Cha "akuwona umnyango wethu lowo." Umzila owodwa nje osuka kumdwebo uye engxenyeni evaliwe.
Okushiwo “Okwethenjelwa” Ngokusebenza—Hhayi Izithembiso
Ukwethembeka akukhona mayelana nokufuna i-ISO 9001. Imayelana nokuletha imibhobho ye-cobalt alloy engu-127 yemojula yokulawula ulwandle lwaseNyakatho—ngesikhathi, enezitifiketi zezinto ezibonakalayo ezigcwele, imibiko yobukhulu, kanye namalogi okuhlola ingcindezi—kanye nokuhlela kabusha iklayenti phakathi namahora angu-48 ngenxa yokuthi amayunithi ayiziro ayedinga ukulungiswa kwenkambu.
Ikhiqiza isisekelo sephampu yensimbi engagqwali engu-210 yezitshalo zokususa usawoti emanzini aseNingizimu-mpumalanga ye-Asia—ngasinye sinemifantu ye-weld prep emishinini engu-±0.15 mm—ngenkathi igcina u-≤2% olahliwe kuwo wonke amaqoqo angu-18.
Isekela amaqembu e-R&D anezibonelo eziguqukayo ngokushesha: isilinganiso samahora angu-72, isihloko sokuqala sezinsuku ezingu-10, umbiko ogcwele we-FAI—okuhlanganisa nezingxenye eziphambanayo zensimbi ezibonisa isikhala sengalo ye-dendrite ezindlini zokutshala imali.
Uma iphrojekthi yakho elandelayo ihlanganisa i-Alloy 4—noma i-AMS 5387, T800, nanoma ikuphi okuhlukile kwe-cobalt-nickel efuna ukungabikho kokuyekethisa ekusebenzeni—ilungelo I-alloy 4 ifektri ngeke nje ihlangabezane nemininingwane. Izolindela izindlela zokuhluleka ongakazifanisi okwamanje. Lowo umehluko phakathi komphakeli nozakwethu.
