Lapho onjiniyela bayacacisa Imboni ye-nickel 400 alloy part ukwesekwa, abagcini nje ngoku-oda insimbi—bafuna ukuzinza kohlangothi ngaphansi kokuhamba ngebhayisikili elishisayo, ukumelana nokugqwala oketshezini olugcwele amanzi nge-chloride, nempilo yokukhathala efana nemvilophu yesevisi yamaphampu asogwini. Sibone amaphrojekthi amaningi emiswa esigabeni se-prototype ngoba abahlinzeki baphathe i-Nickel 400 njengensimbi engagqwali evamile: izindlela zamathuluzi ezifanayo, isu elifanayo lokupholisa, ukubekezelela okufanayo kokuhlola. Akusebenzi. Okuqukethwe kwe-nickel 400 kuka-63% we-nickel, ukusebenza kancane kwe-thermal, kanye nokuthambekela kokuqina komsebenzi kufuna isiyalo esihlukile-esigxilile ekuqwashiseni nge-metallurgical, hhayi nje ikhono lokwenza imishini.
Kungani I-Nickel 400 Ihluleka—Futhi Lapho Izimboni Zangempela Ziphumelela Khona
Ukwehluleka okuningi kulandelela ezinyathelweni ezingalungile ezintathu ezingagwemeka. Okokuqala: ukuthola izinto ezibonakalayo. I-Nickel 400 ayishintsheki kukho konke ukushisa. I-ASTM B164 idinga ukulawula okuqinile kwekhabhoni (<0.3%), isulfure (<0.024%), kanye nensimbi (1.5-2.5%). Sake sathola iqoqo elino-0.42% wekhabhoni—ngaphakathi kwemikhawulo yesitifiketi sokugaya kodwa eyanele ukuqala ukuqhekeka kwe-intergranular ngesikhathi sokunciphisa ingcindezi. Okwesibili: isu lomshini. Amathuluzi ensimbi ajwayelekile anesivinini esiphezulu angena; i-carbide igqoka ngokushesha; ukushisa kwakha lapho kungafanele khona. Izitolo eziphumelelayo zisebenzisa ukusethwa okuqinile, amanani aphansi we-RPM/okuphakelayo okuphezulu, kanye nokupholisa kwe-cryogenic—hhayi ngesivinini, kodwa ukucindezela ukuqina komsebenzi ngaphambi kokuthi kukhiyeke ekuhlanekezeleni kwesakhiwo esincane. Okwesithathu: ukuphatha ngemuva komshini. I-Nickel 400 iyazwela ekucindezelekeni okusalayo. Izingxenye ezifakwe ngomshini ngaphandle kwemijikelezo ekhulula ukucindezeleka zivame ukusonteka phakathi nokuhlanganiswa kokugcina noma zehluleke ukuhlolwa kwe-hydrostatic ku-1.5× ingcindezi yokusebenza.
Amakhono Amane Angaxoxiswana Wokukhiqiza Okuthembekile kwe-Nickel 400
A iqiniso Imboni ye-nickel 400 alloy part kumele ilethe okungaphezu kokubekezelela umdwebo. Kufanele ibe ngumnikazi weketango eligcwele:
- Ukulawulwa kozalo olubalulekile: Izitifiketi zokugaya eziqinisekisiwe, ukulandeleka kwezinga lenqwaba, nokuqinisekiswa kwe-spectrographic yasendlini—hhayi nje ukunikezwa kwamaphepha
- Amathuluzi aqondene nenqubo: Amamaki e-carbide anikelwe anama-TiAlN anamathelayo, okufakwe phansi ngokwezifiso kokusikeka okuphazamisekile emizimbeni yama-valve, nokulungisa okumanziswe ngokudlidliza kwezindlu zamasilinda anezindonga ezincane
- Ukuhlanganiswa kokuphatha okushisayo: Ukunciphisa ingcindezi nge-AMS 2750E ngayinye, ngemephu yesithando somlilo kanye nama-thermocouples okulayisha—“akubhakwa ngobusuku obubodwa” njengokucatshangelwa kamuva
- Ukuqinisekisa okusebenzayo ngale kwe-CMM: Ukuhlolwa kokucindezela kufika kubha engu-700, ukuhlola ukuvuza kwe-helium endaweni evalekayo, nokuqinisekiswa kokuqina kwendawo ezindleleni zokugeleza ezibalulekile kusetshenziswa ama-profilometer—hhayi nje iziqhathanisi zokubona
Lokhu sikuqinisekise ngesikhathi se-oda lakamuva lezindlu zesilinda sephampu ye-piston ezisetshenziswa kuma-subsea hydraulic systems. Ikhasimende belidinga i-Ra ≤ 0.4 µm endaweni ebhorekile yangaphakathi kanye ne-zero porosity engxenyeni yodonga engu-2 mm eseduze nembobo yokukhipha amanzi. Ukufakwa kwesihlabathi okujwayelekile akukwazanga ukuqinisekisa ukuminyana. Ukutshala izimali kulethe ubuqotho—kodwa ngemva kokuba silungise isinxephezelo sokuncipha kwephethini ye-wax ngo-+0.12% ukuze simelane nejika eliyingqayizivele lokuqinisa i-Nickel 400. Lokho kulungiswa kuqhamuke ekwakhiweni kwangaphambilini kwe-17, hhayi kudatha yedatha.
Lokho Amakhasimende Akubuza Empeleni—Ngaphambi Kokucaphuna
Amaqembu okuthenga awaholi ngokuthi “Ingabe unayo i-ISO 9001?” Babuza imibuzo ebukhali:
- “Ungakwazi ukubamba u-±0.015 mm endaweni eyi-300 mm ubude, ngemva kokukhululeka kwengcindezi?”
- "Lithini izinga lakho elijwayelekile lokunqatshwa ezingxenyeni ezidinga > ukususwa kwezinto ezingu-50%?"
- "Ukuqinisekisa kanjani ukufana kwe-microstructure kuwo wonke u-45 kg wokulingisa?"
- "Uma i-GD&T yethu idinga ukubekezelelana kwezikhundla ezihlanganisiwe ezimbotsheni ezintathu zamabhawodi uma kuqhathaniswa nendiza yedatha, iyiphi indlela yakho yokuqala yokuhlola?"
Impendulo akuyona "Sisebenzisa i-CMM." Ithi “Sifaka ingxenye ezimbonini ze-kinematic, siskena indiza ye-datum nge-laser tracker, bese siphenya zonke izici ngokusetha okukodwa—akukho ukubekwa kabusha, alikho iphutha elinqwabelene.” Lelo zinga lobunikazi benqubo lihlukanisa izimboni nezitolo zemisebenzi.
Ukubheka Phambili: Lapho Ukunemba Kuhlangana Nokubikezela
Umngcele olandelayo awukona nje ukubekezelelana okuqinile-ukuvumelana okubikezelayo. Manje sishumeka ukuqapha kwezinga lokushisa kwesikhathi sangempela kuma-spindles e-CNC ngesikhathi sokudlula okunamandla kwe-Nickel 400. Uma izinga lokushisa lokuphotha likhuphuka ngaphezu kuka-38°C, isistimu inciphisa ngokuzenzakalelayo okuphakelayo ngo-12% futhi icuphe ukuqinisekiswa kokugeleza kokupholisa. Hhayi ukuze kuvinjwe ukuphuka kwamathuluzi—kodwa ukugcina ucezu lokusebenza ngaphakathi kwebhande elishisayo elingu-2°C kukho konke ukusika. Kungani? Ngoba i-modulus elastic ye-Nickel 400 ishintsha ngokulinganiswa phakathi kuka-20°C no-45°C. Lolo shintsho lushintsha ukuchezuka ngaphansi kwamandla okucindezela—futhi ukuchezuka kushintsha ukuzungeza kokugcina.
Yilokho okuyiqiniso ngemuva kwakho konke okuthembekile Imboni ye-nickel 400 alloy part: iphatha i-metallurgy njengesinyathelo sokuqala senqubo, hhayi ibhokisi lokugcina elizohlolwa. Iyazi ukuthi ukuchezuka okungu-0.005 mm akukona mayelana nesilinganiso—kumayelana nokuthi ingxenye iyasinda yini kumjikelezo wayo wesithathu wokucindezela eNorth Sea. Uma ingxenye yakho elandelayo ye-Nickel 400 idinga ukwenza—hhayi nje ukudlula ukuhlolwa—imboni oyikhethayo kufanele ikhulume ulimi lwama-athomu, hhayi nje ama-engeli.
