Pamene mainjiniya afotokoza Nickel 400 aloyi gawo fakitale Thandizo, sikuti amangoyitanitsa zitsulo-amafuna kukhazikika kwapang'onopang'ono pansi pa njinga yamoto, kukana kwa dzimbiri mumadzimadzi odzaza ndi chloride, komanso moyo wotopa womwe umafanana ndi envulopu yautumiki wa misonkhano yapampu yakunyanja. Tawona mapulojekiti ambiri akuyimitsidwa pamlingo wofananira chifukwa ogulitsa adatenga Nickel 400 ngati chitsulo chosapanga dzimbiri: njira zomwezo, njira zoziziritsira zomwezo, kulekerera komweko. Sizikugwira ntchito. Nickel 400 ya 63% ya faifi yamtundu wa 63%, kutsika kwamafuta, komanso chizolowezi choumitsa ntchito zimafuna kuphunzitsidwa kosiyana - kozikidwa pa kuzindikira kwazitsulo, osati kungopanga makina.
Chifukwa Chake Nickel 400 Imalephera—Ndipo Komwe Mafakitale Enieni Amachita Bwino
Zolephera zambiri zimatsata njira zitatu zolephereka. Choyamba: kufufuza zinthu. Nickel 400 sisinthana pa kutentha. ASTM B164 imafuna kuwongolera mwamphamvu kwa kaboni (<0.3%), sulfure (<0.024%), ndi chitsulo (1.5-2.5%). Tidalandirapo gulu la 0.42% ya kaboni - mkati mwa malire a satifiketi ya mphero koma yokwanira kuyambitsa kusweka kwa intergranular panthawi yochepetsa nkhawa. Chachiwiri: njira yopangira makina. Zida zamakono zothamanga kwambiri zimakumba; carbide amavala mofulumira; kutentha kumamanga pomwe sikuyenera. Mashopu ochita bwino amagwiritsa ntchito kukhazikika kolimba, mitengo yotsika ya RPM/chakudya chambiri, ndi kuziziritsa kwa cryogenic-osati mwachangu, koma kupondereza kuuma kwa ntchito isanatseke kupotoza kwa microstructural. Chachitatu: kugwira ntchito pambuyo pa makina. Nickel 400 imakhudzidwa ndi kupsinjika kotsalira. Zigawo zomangika popanda zowongolera zochepetsera kupsinjika nthawi zambiri zimazungulira pomaliza kusonkhana kapena kulephera kuyesa kwa hydrostatic pa 1.5 × kugwira ntchito.
Mphamvu Zinayi Zosakambirana Pakupanga Zodalirika za Nickel 400
A zoona Nickel 400 aloyi gawo fakitale ayenera kupereka zambiri kuposa kulolerana pa chojambula. Iyenera kukhala ndi tcheni chonse:
- Kuwongolera kwamtundu wazinthu: Ziphaso zotsimikizika za mphero, kutsatiridwa kwa batch-level, komanso kutsimikizika kwapanyumba - osati kungopereka mapepala
- Zida zogwiritsira ntchito ndondomeko: Magiredi odzipatulira a carbide okhala ndi zokutira za TiAlN, zoyikapo pansi zokhazikika zodulira zoduliridwa pa matupi a valve, ndi zomangira zonyowa ponjenjemera panyumba zokhala ndi mipanda yopyapyala
- Kuphatikizika kwa kayendetsedwe ka kutentha: Kuchepetsa kupsinjika kwa AMS 2750E, ndi mapu a ng'anjo ndi kunyamula ma thermocouples - osati "kuwotcha usiku wonse" monga kuganiza motsatira
- Kutsimikizika kogwira ntchito kupitilira CMM: Kuyesa kukanikiza mpaka mipiringidzo 700, kutayikira kwa helium pa malo osindikizira, komanso kutsimikizika kwapamwamba panjira zovuta zoyenda pogwiritsa ntchito ma profilometer, osati zofananira zowoneka bwino.
Tidatsimikizira izi pakuyitanitsa kwaposachedwa kwa nyumba za silinda zapampu za piston zomwe zimagwiritsidwa ntchito mu subsea hydraulic system. Makasitomala amafunikira Ra ≤ 0.4 µm pamalo obowola mkati ndi zero porosity mu gawo la khoma la 2 mm moyandikana ndi doko lotayira. Kuponya mchenga kokhazikika sikungatsimikizire kuchulukirachulukira. Kuyika ndalama kumapereka kukhulupirika-koma titasintha chipukuta misozi ndi +0.12% kuti tithane ndi mapindikidwe apadera a Nickel 400. Kusintha kumeneku kudachokera ku zomanga 17 zam'mbuyomu, osati zidziwitso.
Zimene Makasitomala Amafunsa—Asananene
Magulu ogula zinthu samatsogolera ndi "Kodi muli ndi ISO 9001?" Iwo amafunsa mafunso ovuta:
- "Kodi mungagwire ± 0.015 mm pa 300 mm kutalika, mutatha kupsinjika maganizo?"
- "Kodi mumakanidwa bwanji pazigawo zomwe zimafuna> 50% kuchotsa zinthu?"
- "Mumatsimikizira bwanji kufanana kwa microstructure pakupanga 45 kg?"
- "Ngati GD&T yathu ikufuna kulolerana kwapang'onopang'ono pamabowo atatu okhudzana ndi ndege, njira yanu yoyamba yoyendera ndi iti?"
Yankho si "Timagwiritsa ntchito CMM." Ndi "Timayika gawolo pamakina a kinematic, kusanthula ndege ya datum ndi laser tracker, kenako ndikufufuza zonse pakukhazikitsa kamodzi - osayikanso, palibe cholakwika chowonjezera." Mulingo wa umwini wamachitidwewo umalekanitsa mafakitale ndi malo ogulitsa ntchito.
Kuyang'ana M'tsogolo: Kumene Kulondola Kumakumana ndi Kuneneratu
Malire otsatirawa samangokhalira kulolerana movutikira-ndilo lolosera mosasinthasintha. Tsopano tikuyika kuyang'anira kutentha kwa nthawi yeniyeni muzitsulo za CNC panthawi ya Nickel 400 yodutsa. Kutentha kwa spindle kukakwera pamwamba pa 38 ° C, makinawo amachepetsa chakudya ndi 12% ndikuyambitsa kutsimikizira kwa kuzizira. Osati kuletsa zida kusweka-koma kusunga chogwirira ntchito mkati mwa 2 ° C matenthedwe bandi kudutsa lonse. Chifukwa chiyani? Chifukwa zotanuka modulus za Nickel 400 zimasinthasintha pakati pa 20°C ndi 45°C. Kusintha kumeneku kumasintha kutembenuka pansi pa mphamvu yokakamiza - ndipo kupatuka kumasintha mozungulira komaliza.
Ndicho chenicheni kumbuyo kwa aliyense wodalirika Nickel 400 aloyi gawo fakitale: imawona zitsulo ngati gawo loyamba, osati bokosi lomaliza loyang'ana. Imadziwa kuti kupatuka kwa 0.005 mm sikukhudzana ndi kuyeza - ndizokhudza ngati gawolo limapulumuka kuzungulira kwake kwachitatu ku North Sea manifold. Ngati chigawo chanu chotsatira cha Nickel 400 chiyenera kuchita—osati kungoyang’ana—fakitale imene mwasankha iyenera kulankhula chinenero cha maatomu, osati ma angles okha.
