Xa iinjineli zichaza I-Nickel 400 inxalenye yomzi-mveliso we-alloy inkxaso, abagcini nje uku-odola isinyithi-bafuna ukuzinza kwe-dimensional phantsi kwe-thermal cycling, ukumelana nokugqwala kwi-chloride-laden hydraulic fluid, kunye nobomi bokudinwa obuhambelana nemvulophu yenkonzo yeendibano zempompo zangaphandle. Sibone iiprojekthi ezininzi kakhulu zimile kwinqanaba leprototype kuba ababoneleli baphatha i-Nickel 400 njengentsimbi eqhelekileyo: iindlela zesixhobo ezifanayo, isicwangciso esifanayo sokupholisa, ukunyamezela okufanayo kokuhlola. Ayisebenzi. I-Nickel 400 ye-63% ye-nickel content, i-conductivity ephantsi ye-thermal, kunye nokuthambekela kokuqina komsebenzi kufuna isiyalo esahlukileyo-enye igxininise ekuqapheliseni i-metallurgical, kungekhona nje amandla omatshini.
Kutheni iNickel 400 Isilela—Kwaye Apho Iifektri Zokwenene Ziphumelela
Uninzi lweentsilelo lulandela kumanyathelo amathathu anokuthi aphepheke. Okokuqala: ukufumana izinto eziphathekayo. I-Nickel 400 ayinakutshintshwa xa kushushu. I-ASTM B164 ifuna ulawulo olungqongqo lwekhabhoni (<0.3%), isulfure (<0.024%), kunye nentsimbi (1.5-2.5%). Sakhe safumana ibhetshi nge-0.42% yekhabhoni-ngaphakathi kwemida yesatifikethi sokugaya kodwa ngokwaneleyo ukuqalisa ukuqhekeka kwe-intergranular ngexesha lokunciphisa uxinzelelo. Okwesibini: iqhinga lomatshini. Izixhobo zentsimbi eziqhelekileyo zigrumba; i-carbide inxiba ngokukhawuleza; ubushushu bakha apho bungafanelekanga. Iivenkile eziphumelelayo zisebenzisa i-setups eqinile, i-RPM ephantsi / imilinganiselo yokutya ephezulu, kunye nokupholisa kwe-cryogenic-kungekhona isantya, kodwa ukucinezela umsebenzi onzima ngaphambi kokuba itshixe kwi-microstructural distortion. Okwesithathu: ukuphatha emva komatshini. I-Nickel 400 inovakalelo kuxinzelelo olushiyekileyo. Amacandelo awenziwe ngaphandle kwemijikelezo yokunciphisa uxinzelelo ahlala ejikeleza ngexesha lendibano yokugqibela okanye angaphumeleli kuvavanyo lwe-hydrostatic kwi-1.5 × uxinzelelo lokusebenza.
Izakhono ezine ezingenakuThengiswa kwi-Nickel ethembekileyo ye-400 yeMveliso
Yinyani I-Nickel 400 inxalenye yomzi-mveliso we-alloy kufuneka inike ngaphezu kokunyamezelana kumzobo. Kufuneka ibe ngumnikazi wekhonkco elipheleleyo:
- Izinto eziphathekayo zokulawula umnombo: Izatifikethi zokusila eziqinisekisiweyo, ukulandelelwa kwinqanaba le-batch, kunye nokuqinisekiswa kwe-spectrographic yangaphakathi-hayi nje ukuhanjiswa kwamaphepha
- Inkqubo-isixhobo esithile: Amabanga eCarbide anikezelweyo aneetyatyekwe zeTiAlN, ufakelo oluqhelekileyo lomhlaba lokusikeka okuphazamisekileyo kwimizimba yevalvu, kunye nokulungiswa okumanziswe kukungcangcazela kwezindlu ezibhityileyo zecylinder
- Ukudibanisa ulawulo lwe-Thermal: I-annealing yokunciphisa uxinzelelo nge-AMS 2750E, kunye nemephu yesithando somlilo kunye nokulayisha i-thermocouples- "engabhakwa ngobusuku" njengengcamango yamva
- Ukuqinisekiswa okusebenzayo ngaphaya kweCMM: Uvavanyo loxinzelelo ukuya kuthi ga kwi-700 bar, ukuvuza kwe-helium kujongwe kwindawo yokutywinwa, kunye nokuqinisekiswa koburhabaxa bomphezulu kwiindlela ezihamba phambili zisebenzisa iprofilometers-hayi nje ukuthelekisa okubonakalayo.
Sikuqinisekisile oku ngexesha lomyalelo wamva nje wezindlu zepiston pump cylinder ezisetyenziswa kwiinkqubo ze-hydraulic zangaphantsi. Umthengi ufuna i-Ra ≤ 0.4 µm kumphezulu wobhobho wangaphakathi kunye ne-zero porosity kwicandelo le-2 mm eludongeni elikufuphi nezibuko lokukhupha. Ukwenziwa kwesanti okusemgangathweni akunakuqinisekisa ukuxinana. I-investment casting ihambisa ingqibelelo-kodwa kuphela emva kokuba silungelelanise imbuyekezo ye-wax ye-shrinkage ye-wax nge-0.12% ukuchasana ne-Nickel 400 ye-curve yokuqinisa ekhethekileyo. Olo hlengahlengiso luvela kwi-17 yangaphambili yokwakha, hayi i-database.
Oko Abakubuza Ngokwenene—Ngaphambi kokuba Bacaphule
Amaqela okuthenga akakhokeli ngokuthi "Ngaba unayo i-ISO 9001?" Babuza imibuzo ebukhali:
- “Ngaba unokubamba u-±0.015 mm kumbhobho omde wama-300 mm, emva kokuthomalalisa uxinzelelo?”
- "Sithini isantya sakho sokwaliwa kwiindawo ezifuna>50% ukususwa kwezinto?"
- "Ukuqinisekisa njani ukufana kwe-microstructure kwi-45 kg yokuphosa?"
- "Ukuba i-GD&T yethu ifuna unyamezelo oludityanisiweyo kwimingxunya emithathu yebholiti ngokunxulumene nenqwelomoya yedatha, yeyiphi inyathelo lakho lokuqala lokuhlola?"
Impendulo ayikho "Sisebenzisa i-CMM." Yithi "Sifaka indawo kwindawo ye-kinematic locators, siskena inqwelomoya nge-laser tracker, emva koko siphonononge zonke iimpawu ngokuseta olunye-akukho kubekwa ngokutsha, akukho mpazamo yongezelekayo." Elo nqanaba lobunini benkqubo lahlula iifektri kwiivenkile zemisebenzi.
Ukujonga Phambili: Apho Ukuchaneka Kudibana Nokuqikelelwa
Umda olandelayo awukho nje ukunyamezela okuqinileyo-kukuqiniswa kwangaphambili. Ngoku sishumeka ukujonga ubushushu bexesha lokwenyani kwi-CNC spindles ngexesha le-Nickel 400 yokupasa. Xa iqondo lokushisa elisontayo linyuka ngaphezu kwe-38°C, inkqubo iyayinciphisa ngokuzenzekelayo isondlo nge-12% kwaye ibangele uqinisekiso lokuhamba okupholisayo. Hayi ukuthintela ukuphuka kwesixhobo-kodwa ukugcina i-workpiece ngaphakathi kwe-2 ° C ye-thermal band kulo lonke ukusika. Ngoba? Kuba i-Nickel 400's elastic modulus itshintsha ngokulinganiswayo phakathi kwe-20°C kunye ne-45°C. Olo tshintsho lutshintsha ukuphambuka phantsi kwamandla okubamba-kwaye ukuphambuka kutshintsha umjikelo wokugqibela.
Leyo yinyani emva kwayo yonke into ethembekileyo I-Nickel 400 inxalenye yomzi-mveliso we-alloy: ithatha i-metallurgy njengenyathelo lokuqala lenkqubo, kungekhona ibhokisi yokugqibela yokujonga. Iyazi ukuba ukuphambuka kwe-0.005 mm akukho malunga nokulinganisa-malunga nokuba inxalenye iyasinda kumjikelezo wayo wesithathu woxinzelelo kwi-North Sea manifold. Ukuba icandelo lakho elilandelayo le-Nickel 400 kufuneka lisebenze-kungekhona nje ukudlula ukuhlolwa-umzi-mveliso owukhethayo kufuneka uthethe ulwimi lweeathom, kungekhona nje ii-engile.
