Alloy 400 ibice bitanga imbaraga zidasanzwe zo kurwanya ruswa munganda zikora ubukana, marine, hamwe na chloride nyinshi-inganda cyane cyane aho ibyuma bitagira umwanda byananiranye. Muri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Twakoze ibice birenga 12.000 Alloy 400 kuva muri 2018 kumibiri ya valve hydraulic, amazu ya pompe yo hanze, hamwe na compressor imbere. Buri gice gitangirana na bilet yemewe na ASTM B164, ihura nigabanuka ryikibazo mbere yuko CNC ihinduka, ikarangirana nuburinganire bwa Ra ≤0.8 μm-nta na kimwe kidasanzwe.
Kuberiki Alloy 400 Ibice Birenze Ibindi Mubikorwa Byukuri-Isi
Abakiriya barabaza bati: “Kuki utakoresha gusa 316 idafite ingese cyangwa duplex?” Igisubizo kiri mumyitwarire yamashanyarazi-ntabwo ari udutabo twamamaza. Alloy 400 (Ni - Cu, ~ 67% Ni / 30% Cu) irwanya kugabanya aside nka hydrofluoric na sulfurike aho passivation yananiwe. Twabonye 316 valve yangirika mumezi 9 imbere mumurongo wohereza aside fosifori; umusimbura Alloy 400 piston inkoni yamaze imyaka 4.7. Ubudahangarwa bwabwo bwo gutobora amazi yo mu nyanja hamwe no guturika-kwangirika ntabwo ari theoretical-bigenzurwa muri laboratoire yacu yemewe na ISO 17025 ikoresheje ibizamini byo kwibiza ASTM G36 hamwe na ASTM F1113 isuzuma ryihuse-ryihuse.
Ariko Alloy 400 ntabwo icomeka-ikina. Igipimo cyacyo cyo kunaniza akazi gisaba ibikoresho byabugenewe: gushyiramo karbide ifite isura ya rake isukuye, ubujyakuzimu butagabanije (mm 0.3 mm), hamwe na firimu ikonjesha ku muvuduko wa bar. Umukiriya umwe yagerageje kuyitunganya kumisarani yumurage hamwe nigikoresho cya HSS - byatumye igipimo cya 42% gisakara hamwe nibimenyetso byo kuganira birenga GD&T kwihanganira ± 0.025 mm. Ubu dushyiramo imashini yubusa hamwe na RFQ, dushyira ahagaragara ibibazo bishobora kugorana nko kugoreka urukuta ruto cyangwa kwagura ubushyuhe budahuye mugihe cyo kuvura ubushyuhe.
Aho Imashini Itunganijwe Ihurira Ruswa-Critical Geometry
Kunanirwa kwinshi ntibituruka kumahitamo yibintu - ahubwo nibikorwa bya geometrie. Ubuso budahwitse hejuru yumubiri wa Alloy 400 yumuvuduko urashobora kwihuta kwangirika kwa 300%. Niyo mpamvu inzira yacu ikubiyemo metrology mubyiciro bitatu: mbere yo gutunganya CMM igenzura ryububiko bubisi, murwego rwo guhitamo optique yo gupima neza umurongo uyobora neza (ingenzi kuri API 6A irembo rya valve), hamwe nubuso bwanyuma bwo kurangiza binyuze muri interferometrie yera.
Mubisanzwe dukora ibice abaguzi basanzwe bagabanuka: 120-mm-diametre Alloy 400 silinderi ifite 0,01 mm yuburebure bwurukuta rwuburebure bwa mm 450; pompe idafite uruzitiro rusaba ± 0.008 mm silindrike; hamwe no gufunga amajwi hamwe na 0.005 mm yibanze hagati yimbere no gusohoka. Ibi ntabwo ari kwihanganira-turabyemeza. Ibicuruzwa byose birimo raporo yuzuye ikurikiranwa nubuziranenge bwa NIST, hiyongereyeho na raporo y'ibizamini by'uruganda rwerekana ibipimo nyabyo bya Cu / Ni / Fe / C - ntabwo "bihuye na spec."
Kuva muri Casting kugeza Kurangiza: Impamvu Vertical Integrated Matters
Abacuruzi bamwe batanga Alloy 400 casting hanyuma bakayikora. Ntabwo. Kubera iki? Kuberako gutandukanya dendritic muri as-cast Alloy 400 itera uturere twa Cu dukungahaye cyane dukunda kwibasirwa. Igikorwa cacu cyo guta umucanga gikoresha igipimo cyo gukomera hamwe na homogenisation nyuma ya 1150 ° C mumasaha 4 - byagenzuwe nisesengura rya microprobe. Ibi bivanaho guhambira, kwemeza 67.2 ± 0.3% Ni ikwirakwizwa rya Ni, kandi bitanga ubukana buhoraho (130-160 HBW) mubice byose.
Igenzura rigera no kurangiza. Electropolishing ikora nabi kuri Alloy 400 kubera microstructure yibice bibiri. Ahubwo, dukoresha citric-nitric passivation ivanze ikurikirwa no gusukura ultrasonic mumazi ya deioniyo - byemejwe muburyo bwa ASTM A967 D. Abakiriya bavuga ko 2.3 life ubuzima bumara igihe kinini muri chloride yuzuye ubukonje ugereranije nubundi buryo bukoreshwa neza.
Guhitamo Iburyo Bwuzuye 400 Igice-Kurenga Urupapuro
Shakisha ibimenyetso bitatu: Icya mbere, ibimenyetso byerekana isesengura ryukuri-kwisi-ntabwo ari amagambo yubahirizwa gusa. Tugumana urutonde rusange rwiperereza ryatewe nimpamvu (itazwi) ikubiyemo hydrogène yinjira muri serivisi ya H₂S hamwe na galvanike hamwe nicyuma cya karubone. Icya kabiri, ibyanditswe byerekana kugenzura: Berekana igihe cyo gushiramo? Igipimo gikonje? Kugenzura ingano y'ibinyampeke kuri ASTM E112? Icya gatatu, kwitabira guhamagarwa kwa GD&T - cyane cyane umwirondoro, kwiruka, n'umwanya uhuriweho. Niba igishushanyo cyawe kigaragaza abahindura MMC cyangwa simulator ya datum, itsinda ryabo rigomba kuvuga urwo rurimi neza.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikora muri ubu buryo kuko ibice birwanya ruswa ntabwo ari ibicuruzwa. Nibishoboza sisitemu. Igice kimwe cya Alloy 400 kunanirwa mugice cyo kugenzura munsi yinyanja birashobora gukurura $ 2.4M mugiciro cyo hasi. Niyo mpamvu dufata gahunda zose-kuva prototype kugeza kumusaruro-nkibikorwa-bikomeye. Turohereza Alloy ibice 400 muri Amerika ya Ruguru, Uburayi, no mu majyepfo y’amajyepfo ya Aziya hamwe n’ibikoresho byuzuye, ibyemezo bifatika, hamwe n’ubuhanga bw’ubwubatsi byubatswe muri cote - ntabwo byongeweho nk'inyongera.
Kubisaba gusaba zeru zeru kubirwanya ruswa, ubudahemuka buringaniye, hamwe no guhuza ibyuma-Alloy ibice 400 biva muri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. zashizweho gukora, zemejwe kubigaragaza, kandi zitangwa kugirango sisitemu ikore.
