Apo mainjiniya anotsanangura Nickel 400 alloy chikamu fekitari tsigiro, havasi kungoodha simbi-varikuda kudzikama pasi pemabhasikoro ekupisa, kusagadzikana kwecorrosion mu chloride-laden hydraulic fluid, uye hupenyu hwekuneta hunoenderana nehamvuropu yebasa yemagungano epombi yekumahombekombe. Takaona mapurojekiti akawandisa achimira padanho remuenzaniso nekuti vatengesi vaibata Nickel 400 sesimbi isina tsvina: nzira dzematurusi dzakafanana, zano rekutonhorera rakafanana, kushivirira kwakafanana kwekuongorora. Hazvishande. Nickel 400's 63% nickel content, low thermal conductivity, uye kushanda-kuomesa maitiro zvinoda chirango chakasiyana-imwe yakadzika midzi mukuziva kwesimbi, kwete kungokwanisa kugadzira.
Nei Nickel 400 Ikundikana—Uye uko Mafekitari Chaiyo Anobudirira
Kukundikana kwakawanda kunotora matanho matatu anogona kudzivirirwa. Kutanga: kutsvaga zvinhu. Nickel 400 haichinjike pakupisa. ASTM B164 inoda kudzora kwakasimba kwekabhoni (<0.3%), sarufa (<0.024%), uye iron (1.5-2.5%). Isu takambogamuchira batch ine 0.42% kabhoni-mukati memill zvitupa zviganho asi zvakakwana kukonzeresa intergranular kupaza panguva yekunetseka-kuzorodza annealing. Chechipiri: machining strategy. Maturusi esimbi akajairika anochera mukati; carbide inopfeka nekukurumidza; kupisa kunovaka paisingafaniri. Zvitoro zvinobudirira zvinoshandisa zvigadziriso zvakaomesesa, yakaderera RPM/yakakwirira mareti ekudya, uye cryogenic kutonhora-kwete yekumhanyisa, asi kudzvanyirira basa kuomarara isati yavharika mukukanganiswa kwemicrostructural. Chechitatu: post-machining kubata. Nickel 400 inonzwa kune yakasara kusagadzikana. Zvikamu zvakagadzirwa pasina kushushikana-kudzoreredza matenderedzwa anowanzo kutenderera panguva yekupedzisira gungano kana kutadza hydrostatic kuyedzwa pa1.5 × kushanda kumanikidza.
Zvina Zvisingataurwi Zvinogona Kuvimbika Nickel 400 Kugadzira
A chokwadi Nickel 400 alloy chikamu fekitari inofanira kuunza zvinopfuura kushivirira padhirowa. Inofanira kunge iri muridzi wetani yakazara:
- Material pedigree control: Verified mill certs, batch-level traceability, uye in-house spectrographic verification-kwete chete mapepa handoffs
- Process-chaiyo tooling: Makaredhi akatsaurirwa ecarbide ane TiAlN coatings, tsika-ivhu inoiswa kune yakakanganisika kucheka pamiviri yevharuvhu, uye vibration-yakanyoroveswa zvigadziriso zveatete-walled silinda dzimba.
- Thermal management kubatanidzwa: Kubvisa kushushikana-kuremerwa neAMS 2750E, ine mepu yechoto uye inotakura thermocouples-kwete "kubikwa husiku" sekufunga kwakatevera
- Kushanda kusimbiswa kupfuura CMM: Kuyedza kudzvanya kusvika ku700 bar, helium inovuza inotarisa panzvimbo yekuvharisa, uye kuomarara kwepasi panzira dzakakosha dzinoyerera uchishandisa maprofilometers - kwete kungoenzanisa kwemaziso.
Isu takasimbisa izvi panguva ichangoburwa yepiston pombi silinda dzimba dzinoshandiswa mu subsea hydraulic system. Mutengi aida Ra ≤ 0.4 µm pazvibhorani zvemukati uye zero porosity muchikamu chemadziro che 2 mm chakatarisana nechiteshi chekuburitsa. Kukandwa kwejecha kwakajairwa hakugone kuvimbisa kuwanda. Investment casting yakaunza kutendeseka-asi chete mushure mekunge tagadzirisa wax pattern shrinkage muripo ne +0.12% kupikisa Nickel 400 yakasarudzika solidification curve. Iyo gadziriso yakabva 17 yekutanga kuvaka, kwete dhetabheti.
Zvinonyatso bvunzwa neVatengi-Vasati Vataura
Zvikwata zvekutenga zvinhu hazvitungamiri ne "Une ISO 9001?" Vanobvunza mibvunzo yakaoma:
- "Unogona here kubata ± 0.015 mm pane 300 mm kureba kubereka, mushure mekuzorora kwekushushikana?"
- "Ndeipi yako yakajairika yekurambwa pazvikamu zvinoda> 50% kubviswa kwezvinhu?"
- "Unoona sei kufanana kwe microstructure pane 45 kg yekukanda?"
- "Kana GD&T yedu ichidaidzira kushivirira kwenzvimbo pamaburi matatu ane hukama nendege yedatum, ndeipi nzira yako yekutanga yekuongorora?"
Mhinduro haisi "Tinoshandisa CMM." Iyo "Isu tinoisa chikamu pane kinematic locators, tarisa iyo datum ndege ine laser tracker, tobva taongorora zvese maficha mune imwechete setup-hapana repositioning, hapana kuwedzera kukanganisa." Iyo nhanho yevaridzi vemaitiro inoparadzanisa mafekitori kubva kuzvitoro zvemabasa.
Kutarisa Mberi: Apo Precision Inosangana Nekufanotaura
Muganhu unotevera hausi kungoomesesa kushivirira - ndeyekufanotaura kuenderana. Isu tave kuisa chaiyo-nguva yekutarisa tembiricha muCNC spindles panguva yeNickel 400 roughing inopfuura. Kana tembiricha yekuruka ichikwira pamusoro pe38 ° C, sisitimu inodzikisira chikafu ne12% uye inokonzeresa kuyerera kwekuyerera. Kwete kudzivirira kuputsika kwechishandiso-asi kuchengetedza workpiece mukati me 2 ° C thermal band kumativi ose akachekwa. Sei? Nekuti Nickel 400's elastic modulus inoshanduka zvine mwero pakati pe20°C ne45°C. Iko kushanduka kunoshandura kutsauka pasi pesimba rekumanikidza-uye kutsauka kunoshandura kutenderera kwekupedzisira.
Ndicho chokwadi chiri kumashure kwese kwakavimbika Nickel 400 alloy chikamu fekitari: inobata simbi sedanho rekutanga rekuita, kwete yekupedzisira dhizaini bhokisi rekutarisa. Inoziva kuti kutsauka kwe 0.005 mm hakusi kwekuyera- ndezvekuti chikamu chinopona kutenderera kwayo kwechitatu muNorth Sea manifold. Kana chikamu chako chinotevera cheNickel 400 chichida kuita-kwete kungopfuura pakuongorora-fekitari yaunosarudza inofanira kutaura mutauro wemaatomu, kwete makona chete.
