I-N04400 yokukhangela umzi-mveliso ayikokufumana esona sicatshulwa sisezantsi-imalunga nokukhusela imfezeko yemathiriyeli ngaphambi kokuba kuqale ukusebenza. Siye sabona izindlu ezininzi zempompo ziqhekeka ngexesha lovavanyo lwe-hydrotesting kuba isatifikethi sokusila asikhange sihambelane nokwenyani kwe-intergranular corrosion resistance. Kwiziko lethu le-Qingdao, yonke i-billet ye-N04400-nokuba ye-AMS 5387-ehambelana nezihlalo ze-cobalt-nickel ye-cobalt okanye i-T800-alloy winch shafts-ifumana ukuqinisekiswa kabini: uhlalutyo lwe-spectrometric * kunye * kunye novavanyo lwe-ASTM B164 kwi-tensile efanayo. Yiloo ndlela esithintela ngayo imeko "eqinisekisiweyo kodwa esengozini" ephazamisa amaxesha e-OEM.
Kutheni “ifektri ye-N04400” ithetha okungakumbi kunokuphosa okanye ukuqengqeleka nje
Ukusebenza kwe-N04400 yokwenyani kuxhomekeke kwizinto ezintathu ezingaxoxiswanayo: ukuqina okulawulwayo, ukwahlukaniswa okuncitshisiweyo, kunye nembali yobushushu enokulandeleka. Ababoneleli abaninzi babhala imathiriyeli njenge "N04400" emva kokuhlolwa kokwakheka okusisiseko-kodwa batsibe ukuqinisekiswa kwe-microstructure. Ekusebenzeni, oko kukhokelela ekuziphatheni okungahambelaniyo: ibhetshi enye iyancipha ngokucocekileyo kwi-85 m / min; iingxoxo ezilandelayo kwi-45 m / min, ukunyanzelisa utshintsho lwezixhobo phakathi kwe-run. Umzi-mveliso wethu we-N04400 udibanisa ukunyibilika kwe-vacuum kunye nolawulo lokuqinisa oluthe gqolo. Ingot nganye ifakwe kwimephu ye-dendritic spacing kunye ne-sulfur stringer distribution-data esabelana ngayo nabathengi ngaphambi kokusika. Kwiivalvu zoxinzelelo ezifunayo <0.5 μm Ra umphezulu wokugqiba, oku kuphelisa umsebenzi ongacwangciswanga. Kwizindlu ze-piston pump cylinder ezisebenza kwi-4,000 psi, ikhusela ukuqaliswa kwe-microcrack phantsi kokulayisha i-cyclic.
Apho i-N04400 esemgangathweni i-specs iwa mfutshane-kunye nendlela esivala ngayo i-gap
I-ASTM B164 ichaza imida yeekhemikhali ze-N04400-kodwa ayithethi nto malunga nomda we-grain boundary carbide precipitation kinetics. Ezinye ii-mill zizisa imathiriyeli ngaphakathi kwe-spec kodwa zisilele kuvavanyo olukhawulezileyo lokubeka i-chloride-rich hydraulic fluid. Silungisa oku ngokubamba yonke into ye-N04400 kwi-650 ° C kwiiyure ze-2 emva kwe-annealing, emva koko i-air-cooling. Oku kuzinzisa i-matrix ye-Ni-Cu ngokuchasene ne-leaching ekhethiweyo ngelixa ugcina i-ductility. Abathengi banika ingxelo ye-3.2 × ubomi obude benkonzo kwiindibano zempompo zangaselunxwemeni zisebenzisa olu nyango. Okubaluleke kakhulu, asiziphathi zonke iibhetshi ngokufanayo: umxholo wesulfure> i-0.005% ibangela ukubamba ixesha elongeziweyo; iintsalela ze-titanium>0.02% amazinga okupholisa shift. Ukuguquguquka kwelizwe lokwenyani kufuna impendulo yexesha lokwenyani-hayi amaxwebhu enkqubo emileyo.
Ukusuka kwibar ekrwada ukuya kwindawo ebaluleke kakhulu: inzuzo ethe nkqo
Uninzi lwababoneleli be-N04400 bayeka ukubonelela ngezinto eziphathekayo. Siqala apho-kwaye siphethe inyathelo ngalinye emva. Xa i-OEM yaseYurophu idinga imilomo ye-cobalt yealloy eyi-120 eyenzelwe isitofu sobushushu obuphezulu, basithumelela umzobo one-±0.01 mm GD&T callouts kunye nomhla wokugqibela weeveki ezili-10. Nantsi into eyenzekayo: i-metallurgists yethu yaqinisekisa iprofayili ye-N04400 ye-billet eshushu-yokusebenza kuqala; Iqela lethu le-CNC liye lalinganisa ukuhanjiswa komthwalo wetshiphu kuzo zonke iikhonto ezintsonkothileyo zangaphakathi; iqela lethu lokugqiba liqinisekisiwe iiparamitha ze-electropolish ngokuchasene neemfuno ze-ASTM A967 passivation. Akukho handoffs. Akukho kulibaziseka komntu wesithathu. Yonke indawo yokuhlola-ukusuka kwizinto ezingenayo i-CMM ihlola ukuya kwiingxelo zokugqibela zokuvuza-zihlala kumsonto omnye wedijithali. Yiyo loo nto i-73% yee-odolo zethu ze-N04400 ziphinda zibaleka kwicandelo elifanayo elisebenzayo.
Ukukhetha iqabane lakho lasefektri i-N04400: imibuzo emithathu ebhenca isakhono
- Ngaba ungandibonisa iingxelo ezintathu zokugqibela zokuvavanya ubushushu obugcweleyo-kubandakanywa ukubola kwe-intergranular (i-ASTM G28 Indlela A) kunye novavanyo olucothayo loxinzelelo kwi-3.5% ye-NaCl? Ukuba bayathandabuza, i-QA yabo iyayeka kwi-chemistry.
- Ngaba umatshini u-N04400 endlwini-okanye ukhupha ngaphandle emva kokunikezelwa? I-off-site machining iphula ukuqhubeka kwembali ye-thermal kwaye ibeka ingozi ekungcoleni komhlaba.
- Yeyiphi inkqubo yakho yokuvelisa ixesha elide le-N04400-kwaye yeyiphi indlela yokungaphumeleli oye wayisusa ngokusebenzisa inkqubo yokuphindaphinda? Iimpendulo zityhila ukuba ngaba bafunda kwidatha yendawo okanye izatifikethi zokuthumela ngenqanawa.
Siqhube inkqubo efanayo ye-N04400 yesiseko sempompo iminyaka esibhozo. Iibhetshi zakwangoko zibonise i-micro-pitting kwiindawo zokujongana. Unobangela weengcambu? I-manganese oxide encinci inclusions esebenza njengezigxininisi zoxinzelelo. Isisombululo: yongeza unyango lwe-calcium kwi-melt kwaye yazisa i-ultrasonic immersion yokucoca i-pre-machining. Ayisiyiyo nje into yokuvelisa-oko bubugosa be-metallurgical. Xa ufuna imveliso ethembekileyo ye-Nickel Alloy 400, qalisa apho ibali lezinto eziphathekayo liqala khona-kungekhona apho i-invoyisi iyenzayo.
