Lapho onjiniyela baseNyakatho Melika noma eYurophu bedinga a China metal Casting umenzi ekwazi ukuletha amavalvu okucindezela abamba ukubekezelelana okuqinile kubha engu-350—noma imibhobho ye-cobalt alloy esinda ku-650°C emibuthanweni yephampu yase-oilfield—ayimane nje ifune “isisekelo esinezindleko eziphansi.” Basesha isilawuli se-metallurgical esifakazelwe, isiyalo sobukhulu, kanye nokungabekezeleli lutho kokungahambisani kwe-microstructural. Kulapho ukunemba kubaluleke khona ngaphezu kwentengo—futhi lapho i-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ihola ama-oda aphindayo kuma-OEMs we-hydraulic system kanye nezihlanganisi zemishini yasogwini.
Akuwona Wonke Ama-Castings Adalwa Ngokulingana—Ikakhulukazi Ngaphansi Komthwalo
Sibone amaphrojekthi amaningi ebambezelekile—hhayi ngamaphutha edizayini, kodwa ngezinto ezimangalisayo ezimangalisayo. Indlu yesilinda sephampu ye-piston eyenziwe ngomshini wensimbi esantiwe yehluleka ukuhlolwa kokudlidliza ngenxa yokuthi isibalo samanodule e-graphite siwele ngaphandle kokucaciswa kwe-ASTM A278 Class 30. Ipulaki ye-cobalt-nickel iyaqhekeka phakathi nokuhamba ngebhayisikili elishisayo ngenxa yokuthi isikhala sengalo ye-dendrite se-as-cast siye sahluka ngalé kuka-±12 µm ekushiseni. Lezi akuzona izingozi zethiyori. Amamodi okuhluleka aqinisekiswe inkambu esisize amakhasimende ukuba awagweme kusukela ngo-2014.
I-QINGDAO QIANGSENYUAN ayikuphathi ukusakaza njengenqubo ezimele. Iyithatha njengesinyathelo sokuqala esibalulekile kuketango elihlanganiswe ngokuqinile: ukusakaza → ukukhululeka kwengcindezi → imishini ye-CNC → ukwelashwa kokushisa → ukuqinisekiswa kobuqotho obungaphezulu. Isikhungo sabo esithobela i-ISO siqhuba ukufakwa kwezimali kokutshala kwezingxenye ze-AMS 5387 ezinodonga oluncane kanye nokusakazwa kwesihlabathi esiluhlaza ezindlini zensimbi ezinengxenye esindayo—ngasinye esinamaphrofayili esithandweni somlilo, izinga lokupholisa izingodo, nokuqinisekiswa kweqoqo le-spectrographic. Yonke into encibilikayo ithwala ukulandeleka okugcwele: inombolo yenqwaba, izinga lokushisa elithelayo, isikhathi sokuqinisa, nemibiko yokuhlolwa komshini oqinisekisiwe evela kubahlinzeki abahloliwe.
Lokhu akuphathelene "nemininingwane yomhlangano." Kumayelana nokulawula okuguquguqukayo amashidi athile angavamile ukukusho—njengokusabalalisa ingcindezi eyinsalela ngemva kokunyakaziswa, noma indlela okusanhlamvu okukuthinta ngayo ukuphila kokukhathala ku-winch center shaft roller ezungezayo ngaphansi kwe-cyclic torsion. Kungakho onjiniyela babo bevamise ukubheka ama-callouts e-GD&T ngokumelene nokusakaza amamephu anciphayo—hhayi nje amapulani.
Kungani I-Cobalt Alloys Idinga Okungaphezu Kwelayisense Yokutholwa
Abanye abakhiqizi babhala "amandla we-cobalt alloy" kuwebhusayithi yabo. Bambalwa abangasakaza izingxenye ezisekelwe ku-T800 ngokungaguquki ezino-≤0.8% we-porosity ezindaweni ezibucayi zendlela yokugeleza—noma babambe ukubekezelelana kwendawo okungu-±0.015 mm kuma-coaxial bores amathathu endaweni yepompo ye-AMS 5387 ngemva kokugaya okokugcina. Umehluko usekuziphatheni kobunikazi.
I-QINGDAO QIANGSENYUAN ingumnikazi wawo wonke ukusakazwa kwevelu: ukuthengwa kwempahla eluhlaza (enezinkontileka eziqondile ze-Haynes 25 kanye ne-Stellite 6 okulingana), ukuncibilika kwe-vacuum induction, ukufakwa kwe-ceramic yamagobolondo okutshalwa kwezimali, umshini we-CNC wama-axis ayisithupha ngenqubo yokuhlola, kanye ne-HIP (ukucindezela okushisayo kwe-isostatic) kwemishini-. Akukho ukwenza umsebenzi omncane. Awekho ama-handoffs. Uma ikhasimende lithumela umdwebo wepulaki ye-cobalt alloy engajwayelekile enamashaneli okupholisa angaphakathi, ithimba elifanayo liphatha ukubuyekezwa kwe-metallurgical, ukulingisa ukugeleza kwesikhunta, isu lomshini, nokuhlola ukuvuza—konke ngaphansi kophahla olulodwa.
Bayazi nokuthi yini *okungafanele bayenze. Isibonelo: ama-sand cast cobalt alloys amema ukuhlukaniswa kwe-carbide. Ngakho-ke basebenzisa ukufakwa kwe-investimenti—ngisho noma kwengeza u-18% ukuze kuhole isikhathi—ngoba iletha ubulukhuni obufanayo (i-HRC 42–46 engxenyeni yonkana) futhi iqeda isidingo sokusebenza kabusha okubizayo kwangemva komshini ngenxa yokuhlanganisa izigaba ezinzima.
Ukusuka Ekudwebeni Kuya Ekuletheni: Lapho Ukusekelwa Kobunjiniyela Empeleni Kwengeza Inani
“Ungakwenza lokhu?” umbuzo wokuqala ongalungile. Okulungile wukuthi: “Yini ezohluleka kuqala—futhi siyinqanda kanjani?” Leyo ilensi QINGDAO QIANGSENYUAN esebenza ngesikhathi sokubuyekezwa kobunjiniyela.
- Ithimba labo lihlaba umkhosi ama-engeli asalungiswa angahambisani nokususwa kwegobolondo le-ceramic—ngaphambi kokuthi kuqale ukusebenza
- Baphakamisa izinguquko ezincane ze-GD&T (isb., ukusuka ekubekezeleleni indawo ukuya ekulawuleni ukuphuma ku-shaft ejikelezayo) ukuze kuthuthukiswe isivuno sokudlula kuqala
- Baqinisekisa imijikelezo yokwelashwa kokushisa ngokumelene nengxenye yangempela yesisindo-hhayi amashadi ajwayelekile-ukugwema ukuhlanekezela ezisekelweni zephampu yensimbi engagqwali.
Lena akuyona ithiyetha eyelulekayo. Kuyimpendulo ebhaliwe, ebuyiselwe phakathi kwamahora angu-72, nemidwebo enezichasiselo nezinye iziphakamiso zezinto ezibonakalayo (isb., ukushintsha kusuka ku-CF8M kuya ku-UNS S32750 duplex yokumelana ne-chloride ezisetshenziswa olwandle). Ngokugijima kwe-prototype, bathumela imibiko yokuhlola enobukhulu enembondela yephuzu le-CMM ngokumelene nejometri yegama-ngakho amakhasimende aqinisekisa ukuthi afanelekile ngaphambi kokuzibophezela ekukhiqizeni.
Ukukhetha Umkhiqizi Wase-China Metal Casting Akukona NgeJografi-Kumayelana Nokugcina Isango
Ukutholwa komhlaba wonke akukhona ukuthola isilinganiso esiphansi kakhulu. Kumayelana nokukhomba ukuthi ubani olawula amasango: isango elimisa ama-ingots asezingeni eliphansi, isango elenqaba ukusakazwa okungalungile ngaphambi komshini, isango elimisa ukuthunyelwa kuze kube yilapho ukuhlolwa kokusebenza kuqinisekisa ukuthi ingcindezi yokuqhuma ibamba umthwalo olinganiselwe ongu-1.5×.
Amandla e-QINGDAO QIANGSENYUAN awanawo isikali—awukukhetha. Asebenza ngokukhethekile ezigabeni ezine zobuqotho obuphezulu: izingxenye zomshini we-CNC, izingxenye zengxubevange ye-cobalt-nickel, ukubunjwa kwensimbi, nokusakazwa kwensimbi/insimbi engagqwali. Akukho okunye. Lokho kugxila kunika amandla ulwazi lwenqubo ejulile, ukuxazululwa kwezinkinga ngokushesha, kanye nemiphumela engaguquki kuwo wonke ama-hydraulic, uwoyela negesi, kanye nezicelo zezimoto ezinzima.
Uma iphrojekthi yakho elandelayo ihlanganisa ama-valve anengcindezi ephezulu, izindlu zokupompa, noma izinsimbi ezibucayi—futhi udinga China metal Casting umenzi okuphatha i-metallurgy njengobunjiniyela, hhayi ukukhiqiza—kuqala ngokulandeleka kwezinto, ukuqondisa kobukhulu, nokuvimbela ukwehluleka komhlaba wangempela. Hhayi iziqubulo zokumaketha.
