Pamene nyumba yanu ya pampu ya hydraulic iphwanyidwa pa 420 ° C, kapena phokoso la aloyi la cobalt likulephera pambuyo pa maola 380 mu ntchito ya gasi wowawasa, simukukumana ndi vuto la makina - mukukumana ndi mkulu kutentha aloyi fakitale kusiyana kwa luso. Taziwonapo nthawi zambiri: magulu a mainjiniya omwe amapeza zida za AMS 5387 kuchokera kuzinthu zomwe zimagwiritsidwa ntchito nthawi zonse, amangopeza ma microsegregation m'magawo otenthedwa ndi kutentha, kutulutsa kwambewu kosasunthika m'malo osasoweka, kapena zopatuka za GD&T zomwe zimangotuluka. Kuchita zenizeni padziko lapansi pakuyenda panjinga zotentha, kupanikizika kwambiri, komanso zoulutsira mawu sizikhululukidwa kuwongolera zinthu kapena umwini wogawanika.
Chifukwa chiyani "High-Temp Alloy" Sichizindikiro Chabe -Ndi Kudzipereka Kwa Njira
Osati aliyense wopanga zitsulo amayenerera kukhala woona mkulu kutentha aloyi fakitale. Ambiri amagwiritsa ntchito ma nickel-based castings-koma ochepa amasunga kutsatiridwa kwathunthu kuchokera ku risiti ya T800 billet yotsimikizika kudzera mu njira yolumikizira, ma contouring amitundu yambiri, komanso kumaliza kotsimikizika kwa CMM. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Timachita ma alloys a cobalt-nickel osati ngati zida zakunja, koma monga machitidwe omwe amadalirana: kuchuluka kwa kulimba kumakhudza kugawa kwa carbide; kutsatizana kwa makina kumatsimikizira kupsinjika kotsalira mu nyumba zokhala ndi mipanda yopyapyala; ngakhale kuzimitsa kutentha kwapakati kumasintha delta pakati pa ASTM A995 Grade CD4MCu ndi kukana kwenikweni kwa dzimbiri m'malo okhala ndi mafuta ambiri a chloride.
Tidamanganso nyumba yolephera ya pampu ya piston ya jekeseni wa North Sea subsea. Gawo loyambirira limagwiritsa ntchito generic IN718 koma linalibe kuwongolera kokhazikika. Kuwunikiridwa kwathu kunayambitsa kuzizirira koyendetsedwa panthawi yopangira ndalama, kutsatiridwa ndi HIP + kukalamba kawiri-ndikuwonjezera moyo wautumiki kuchokera pa miyezi 14 kufika pa 42. Izi sizinali bwino kusankha alloy. Kunali kuwongolera-kutentha-kutentha kwapang'onopang'ono komwe palibe wogulitsa m'modzi yekha akanakhoza kupereka.
Mphamvu Zinayi Zosakambirana Zomwe Simungathe Kuzipereka
A odalirika mkulu kutentha aloyi fakitale Ayenera kukhala ndi mizati inayi—osati yochokera kunja:
- Utumiki wakuthupi: Kugwirizana kwaukadaulo mwachindunji ndi mphero, osati kungogula maoda. Timatsimikizira chiphaso chilichonse cha AMS 5387 chotsutsana ndi kukula kwambewu ya ASTM E112, ASTM E1268 dendrite malo otalikirana ndi mikono, ndi malipoti oyesa amtundu wa intergranular corrosion.
- Kuponya - kuphatikiza makina: Maziko achitsulo choponyera mchenga amapangidwa movutikira asanachepetse kupsinjika. Mabotolo a cobalt oyika ndalama amatha kutembenuka *pambuyo* HIP - osati kale. Izi zimalepheretsa kupotoza komwe kumawononga kulolerana kokhazikika pazithunzi zenizeni za 0.015 mm.
- Dimensional kukakamiza: Osati "kuyesedwa ndi CMM." Timagwiritsa ntchito optical profilometry pamalo osindikizira, kutsimikizira kwa laser tracker pamaziko akulu apompo (mpaka 2.8 m), komanso kutsimikizira kwapakatikati pa 5-axis CNCs - chifukwa kutengeka kwa kutentha panthawi yokonza magawo amtundu wa T800 kumatha kusuntha mozungulira ndi 0.022 mm.
- Kutsimikizira kogwira ntchito: Valavu iliyonse yokakamiza imayesedwa ndi hydrostatic proof pa 1.5 × rated pressure, kuphatikiza kuyesa kwa helium kutayikira pa ISO 15848-2. Palibe "zitsanzo-zokha" kupatula.
Mtengo Wobisika wa Fragmented Sourcing
Ogula ena amagawaniza ntchito: kuponyera kuchokera ku Foundry A, chithandizo cha kutentha kuchokera ku Heat Treater B, kumaliza kuchokera ku Machine Shop C. Koma pulagi ya AMS 5387 ikapanga ma microcracks pafupi ndi muzu wa ulusi, ndani mwini wake? Foundry A akuti mawonekedwe awo a as-cast adakwaniritsa. Heat Treater B imatsimikizira kuti kuzungulira kwawo kumafanana ndi deta. Machine Shop C ikuwonetsa zipika zabwino kwambiri. Pakadali pano, polojekiti yanu ikudutsa masabata asanu ndi limodzi.
Tatsata 31 zomwe zidalephera kutumizidwa pazaka zitatu zapitazi. 68% adatsata mipata pakati pa masitepe opangira-osati zolakwika zakuthupi. Makina oyenga mafuta ku Southeast Asia anakana mapulagi 17 a cobalt alloy plugs chifukwa malo oponyera mchenga sanakonzedweratu kuti achotse zigawo zowotcha zisanathe kutentha. Chigawo chimenecho chinakhala malo opangira ma nucleation osweka pansi pa cyclic thermal load. Kuwongolera kophatikizana kumachotsa madontho akhungu.
Zomwe Muyenera Kufuna Ku Factory Yanu Yotentha Yotentha Yowonjezera -Pakali pano
Musanasaine NDA, funsani mafunso asanu awa ndikuwona momwe akuyankhira:
- "Tiwonetseni ziphaso zanu zomaliza za AMS 5387 - ndi lipoti lofananira la HIP microstructure ndi kusanthula kwa carbide morphology."
- "Kodi mumatsimikizira bwanji kukhazikika pambuyo pa chithandizo cha kutentha pazigawo zomwe zili ndi> 3: 1 makulidwe osiyanasiyana?"
- "Kodi kutentha kwanu kovomerezeka ndi kotani panthawi yowotcherera TIG ya zida za cobalt - ndipo mumaziwunika bwanji munthawi yeniyeni?"
- "Kodi mungapereke kuwonetsetsa kwathunthu kwa nyumba imodzi ya pampu ya pistoni-kuchokera pa ID yosungunuka mpaka lipoti lomaliza loyendera?"
- "Kodi phindu lanu loyamba limakhala lotani pazithunzi zomwe sizikufunika <0.01 mm kulolerana kwa mbiri?"
Ngati mayankho sakumveka bwino, achedwa, kapena atchulanso "miyezo yamakampani" osatchula njira zoyesera - chokanipo. Kulondola sikungakambirane mukamagwira ntchito pa 70% ya malo osungunuka.
Kutentha kwambiri kwa aloyi kumayamba kalekale asanadulidwe kapena kuthira koyamba. Zimayamba ndi kuwongolera zitsulo, kukakamizidwa kudutsa kuponya, kukonza, ndi kumaliza - osaperekedwa pamalire a dipatimenti. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inapanga mbiri yake pakukana kugawikana kumeneko. Malo ake ogwirizana ndi ISO ku Qingdao samangopanga magawo omwe amakwaniritsa zofunikira. Imapereka zinthu zomwe zimapulumuka zomwe sizimagwidwa: kutopa kwamafuta, kukokoloka kwa tinthu tating'onoting'ono, hydrogen embrittlement, komanso kufunikira kosalekeza kwa nthawi yopuma yosakonzekera. Pamene ntchito yanu ikupitirira 500 ° C, kupitirira 10,000 psi, kupitirira miyeso yoyenerera - ndi pamene zoona mkulu kutentha aloyi fakitale amasiya kukhala osankha.
