Gushushanya a umusaruro w'ifu ya metallurgie ntabwo ari ukwigana inyandikorugero. Nibijyanye no gukemura inzitizi zubuhanga nyabwo-kugoreka ubushyuhe mu gucumura, gradients zuzuye muri geometrike igoye, cyangwa icyiciro kimwe kugeza igihe mugihe ukoresheje amavuta ya cobalt-nikel nka AMS 5387 cyangwa T800. Twubatse kandi tunonosora amashanyarazi arenga 12 ya metallurgie - ihuza ibicuruzwa biva mu nganda kuva mu mwaka wa 2016. Buri wese yatangiranye ikibazo kimwe: * Uyu murongo ugomba gutanga iki - atari umusaruro gusa? *
Tangira ufite intego yo gukora, ntabwo inzira yatunganijwe
Inganda nyinshi zananirwa kuri Stage 1: bashushanya ibikoresho mbere yo gusobanura imipaka yimikorere. Umuvuduko wimyubakire ya sisitemu ya hydraulic ntukeneye "ubucucike bukabije" - birakenewe ubucucike bwa radiyo muri ± 0.02 g / cm³ hejuru ya mm 120 ya bore. Urufatiro rwa pompe rusaba umusaruro ushimishije ≥1,420 MPa nyuma ya HIP - ariko gusa muri zone itwara imizigo, ntabwo ari imitsi. Itandukaniro rihindura ibintu byose: igice cyerekezo mugice cyicyatsi kibisi, kugabanura ikirere cyikigereranyo, hamwe no gukanda isostatike ishyushye isimbuza cyangwa ikongeramo icyaha gisanzwe.
Twigeze kongera gukora itanura ryumukiriya wose kubera ko igishushanyo cyabo cyambere cyakoresheje azote ishingiye kuri azote ya cobalt alloy nozzles. Kwiyongera k'ubushyuhe bidateye microcracking kumuhogo wa nozzle - akarere ka mm 0.3. Guhindura imyuka ya vacuum hamwe na argon yagenzuwe yagabanije ibisigazwa biva kuri 22% bikagera kuri 1.7%. Gukosora ntibyari byikora cyane. Byari bihuye no kugenzura ikirere kuri geometrie ikora.
Kwishyira hamwe guhagaritse gukubita modular outsourcing-iyo ikozwe neza
Abacuruzi bamwe bagurisha "powder metallurgy turnkey solutions" nka selile zabanje gupakirwa: atomizer → kanda → itanura rya sinter station Sitasiyo ya CMM. Ariko iyo moderi yirengagije uburyo casting-mashini ya Hybrid ikora neza. Reba inzu ya pisitori ya piston: umugozi wimbere ugomba gutunganywa * nyuma yo gucumura kugirango ubungabunge umutekano - ariko hejuru yimbere igomba kuba hasi * mbere ya * HIP kugirango wirinde kugoreka ibintu.
Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dukoresha imirongo ishora imari hamwe nifu ya metallurgie yifu munsi yinzu imwe yemewe na ISO - ntabwo byoroshye, ahubwo ni ukugenzura amateka yubushyuhe. Iyo igice cya T800 kivuye mu cyatsi kibisi kijya mu gice cyarangiye, imiterere yacyo y’ibinyampeke igenda ihinduka mu byiciro bitatu: gutwika binder (350-600 ° C), gukwirakwizwa-gukomeye (900-1.150 ° C), no gucumura ibice (1,280–1,350 ° C). Ibigo byacu byo gutunganya CNC birahindurwa kugirango byishyure uburyo bwo guhangayika busigaye bupimwe * muburyo * mugihe cyo gukonjesha - amakuru tugaburira muburyo bwo kubyara ibikoresho.
Ibi ntabwo ari theoretical. Niyo mpamvu AMS 5387 cobalt alloy ibice 6 bya pompe bigera kuri GD&T Zone kubahiriza ± 0.008 mm hejuru yikimenyetso gikomeye - nta gutunganya HIP nyuma ya HIP.
Ubwiza ntibugenzurwa. Byakozwe mumyitwarire yibintu
Ifu yuzuye ya metallurgie yubuziranenge ifata ubugenzuzi nkirembo: pass / kunanirwa kugenzura CMM yanyuma. Ibyo biratinze. Guhindagurika kwinshi bitangirira kuvanga ifu. Oxygene iri hejuru ya 350 ppm muri cobalt-nikel mbere y-ifu ya porojeri itera ifumbire mvaruganda mugihe cyo gucumura - ntibishobora kugaragazwa no gupima ubukana.
Igisubizo cyacu gikubiyemo ubugenzuzi ku ngingo enye zitaganirwaho:
- Inyemezabwishyu: Isesengura rya OES + LECO kuri buri kintu; byemewe gukurikiranwa kuri ASTM B243-22
- Icyatsi kibisi kwemeza: Ikizamini cya Uniaxial compression kumasezerano 5 yambere kuri buri mwanya - ntabwo ari ubucucike gusa
- Kugenzura umwirondoro: Igihe nyacyo cyo gushushanya amakarita yimbere muri zone yitanura, yinjiye muri buri cyiciro
- Kurekura Microstructure: SEM-EDS kumurongo wambukiranya ibitambo bya buri cyiciro cya HIP
Ntabwo twemera "ibyemezo bifatika." Twemeza ogisijeni, azote, karubone, hamwe nubunini bwagabanijwe * ubwacu *. Kuberako iyo winch center shaft roller yananiwe kumuzingo 8.200 aho kuba 12.000, intandaro ni gake itunganya-ni chimie yamashanyarazi yatwikiriwe nubushakashatsi bwimbitse.
Umusaruro wifu ya metallurgie uruganda gutsinda biterwa nibyo wasibye
Gukora ibinure muri PM ntabwo ari ugukata umutwe. Ni ugukuraho ubukererwe bwicyemezo. Umukiriya umwe yagabanije igihe cyo kuyobora ku kigero cya 41% ntabwo yongeyeho imashini - ahubwo akuraho ingingo eshatu zihererekanyabubasha hagati yo gutegura ifu, guteganya guhuza, no gucunga umurongo. Sisitemu yabo ya ERP ntishobora gukemura ibibazo byihutirwa mugihe gahunda yo hejuru ya hydraulic valve igiciro cyageze hagati. Twabisimbuje ikibaho cya Kanban cyahujwe nigihe nyacyo cyo gutanura-kandi duhuza nimero ya poweri kumabwiriza yakazi ya digitale agaragara kuri buri kibaho.
Ikimenyetso gikomeye cyumuntu ukuze umusaruro w'ifu ya metallurgie ntabwo isohoka. Nukuntu byihuta guhuza nimpinduka zisobanutse, umuhamagaro mushya wa GD&T, cyangwa umurongo wo kuvugurura ubushyuhe wavuguruwe - byose nta gusubiramo protocole yubugenzuzi. Uwo muvuduko uturuka ku nyandiko zanditse, zisubirwamo: hagati yifu ya morfologiya nicyitegererezo cyimbaraga zicyatsi, hagati yigihe cyo gutura hamwe namakarita yanyuma ya porosity, hagati yumuvuduko wa HIP hamwe numurongo wubuzima.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yubaka ayo masano - ntabwo arikitegererezo, ariko nkibipimo bizima muri sisitemu yo gukora umusaruro. Turabasangira mucyo mugihe cyo gusubiramo injeniyeri kuko gukora ntabwo ari inzitizi. Nibipimo byambere byimikorere.
