Ke hōʻike ʻia e nā ʻenekinia Inconel 718, ʻAʻole lākou e koho wale i kahi mea - ke hana nei lākou i ke kūpaʻa dimensional ma 650 ° C, ke kū'ē i ke koʻikoʻi-corrosion māwae ma nā wahi kinoea ʻawaʻawa, a me ke ola luhi ma lalo o ka cyclic thermal loading. Akā ʻaʻole liʻiliʻi ka manaʻo o nā kikoʻī maka me ka loaʻa ʻole o kahi hoa hana i haku i kāna ʻano ma ka hale kūʻai. Ma laila kahi ʻO Inconel 718 hale hana loaʻa i kona paona—ʻaʻole i loko o nā brochures, akā i ka hana hou ʻana ma nā ʻāpana 200-hapa, i ka GD&T hoʻokō i nā hiʻohiʻona hoʻomanawanui 0.005-mm, a me nā mea kahaha ʻole i ka nānā ʻana i ka ʻatikala mua.
No ke aha i ʻoi aku ai ka "Factory" ma mua o ka "mea hoʻolako" no Inconel 718
Ua ʻike mākou i ka nui o nā papahana i hoʻopaʻa ʻia no ka mea ua loaʻa i kahi hui kalepa ʻo Inconel 718 bar bar mai kahi wili hoʻokahi, hoʻomaʻamaʻa ʻia ma kahi kapuahi ʻekolu, a laila hoʻouna ʻia i kahi hale kūʻai CNC me ka nānā ʻole ʻana i ka metallurgical. Ka hopena? ʻO ka ʻokoʻa microstructure ma waena o nā wela. ʻO ka decarburization o ka ʻili ma nā flanges i huli ʻia. ʻO ke koena o ke koʻikoʻi i hoʻoulu ʻia ma hope o ka mīkini hope loa - ʻike ʻia i ka wā hoʻāʻo hydraulic wale nō. He oiaio ʻO Inconel 718 hale hana nona ke kaulahao: hōʻoia ʻia ka ʻike maka ʻana, ka hoʻoheheʻe ʻana i loko o ka hale a me nā pōʻai kahiko, a me nā ʻāpana mīkini i hoʻopaʻa ʻia ma ka Inconel 718 maoli—ʻaʻole nā mea hoʻonohonoho nickel-alloy generic.
Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., hoʻomaka kēlā me kēia ʻāpana Inconel 718 me AMS 5662-certified billet, hōʻoia ʻia ma o PMI a me OES ma mua o ke komo ʻana i ke kahe hana. ʻAʻole mākou i waho i ka mālama wela. ʻO kā mākou mau kapuahi ʻumeke e hahai pololei i nā lāʻau hoʻohālikelike pyrometer AMS 2750E—a mālama mākou i nā moʻolelo mōʻaukala wela piha i kēlā me kēia ʻāpana. ʻAʻole kēia ma luna. ʻO ia ke ʻano o kā mākou paʻa ʻana i ka ± 0.01 mm ma kahi 320-mm-diameter piston pump cylinder hale ʻoiai e mālama ana i ka Ra 0.4 µm hoʻopau ʻili ma nā ʻāina hoʻopaʻa i loko.
Kahi i hāʻule ʻole ai ka mīkini maʻamau—a he aha ka hana maoli
Hana ʻia kekahi mau hale kūʻai iā Inconel 718 e like me ke kila kila paʻa. ʻAʻole lākou. ʻO 3 × kiʻekiʻe ka nui o kāna hana paʻakikī ma mua o 316SS. E hāʻule ka nui o ka hānai i 40% ma hope o ka hala mua. Piʻi ke ola o ka mea hana inā hāʻule ke kaomi hoʻoluʻu ma lalo o 70 bar. Ua aʻo mākou i kēia ma ke ʻano paʻakikī o ka mīkini ʻana i nā nozzles cobalt-nickel AMS 5387 no nā manifold hydraulic pressure kiʻekiʻe—a hiki i ka wā i hoʻololi ai mākou i ka mea hoʻoluʻu kiʻekiʻe ma o ka milo, nā mea hoʻokomo carbide i uhi ʻia me ka geometry rake maikaʻi, a me nā ala ʻāwīwī kūpono e kaupalena ana i ka manawa noho.
Hoʻohana ʻia kā mākou mea hoʻokō ISO i nā kikowaena mīkini 5-axis i lako no ka wili hohonu ʻana o nā ʻāpana paʻakikī—e like me nā ala kahe i hoʻopaʻa ʻia i loko o nā kiwi kaomi i helu ʻia i 420 bar. Hoʻohui mākou i ka hoʻomaʻamaʻa wela * ma waena o nā hana i ka wā e pono ai: mīkini ʻōpala → solution anneal → hoʻomaha i ke kaumaha → mīkini hoʻopau → paʻakikī makahiki. ʻO ka hoʻokuʻu ʻana i kēlā kaʻina e pilikia ai ka hoʻololi ʻana a i ʻole ka ikaika hua like ʻole. Nīnau pinepine nā mea kūʻai aku i ka loiloi ʻenehana, "No ke aha i hala ai kā mākou hui mua i ka CMM akā ʻaʻole i hāʻule i ka hoʻāʻo ʻana?" ʻAʻole hiki ke kiʻi ʻia ka pane - ʻo ia ke ala wela-mechanical.
Kiola + Mīkini = Hana ʻOiaʻiʻo Hiki iā ʻoe ke ana
ʻAʻole hana ʻia a hana ʻia ʻo Inconel 718. No nā ʻāpana koʻikoʻi koʻikoʻi nui - nā kumu paʻa, nā wili pahu winch center, nā kino valve waho - hāʻawi ka hoʻolei kālā ʻana i ke ʻano o ka ʻupena me ke kahe o ka palaoa. Akā ʻaʻole lawa ka hoʻolei wale ʻana. ʻAʻole lawa ka pale ʻana i ka luhi e pono ai no nā ʻāpana wili. ʻO ia ke kumu o kā mākou ʻO Inconel 718 hale hana hoʻohui i ka hoʻolei kālā me ka pololei CNC hoʻopau: hoʻolei ʻia i ± 0.3 mm, a laila hoʻopaʻa ʻia nā maka mīkini, lawe i nā puke moʻolelo, a me nā puka pae i ± 0.008 mm me ka hōʻoia GD&T piha.
Mālama mākou i ka alignment ʻenehana me nā mea hoʻolako mea e pili ana i ka nui o ka palaoa (ASTM E112), ka helu hoʻopili (ASTM E45), a me ka ʻike delta-ferrite. Loaʻa i kēlā me kēia hoʻolei ʻana i ka radiographic inspection (ASTM E94) a me ka hoʻāʻo ʻana i ka wai penetrant (ASTM E165). ʻAʻohe ʻokoʻa—ʻoiai no nā prototypes. No ka mea i loko o ka aila a me ke kinoea a i ʻole nā noi ma lalo o ka moana, hoʻokahi puʻupuʻu porosity ma kahi piʻi koʻikoʻi ʻaʻole ia he "liʻiliʻi liʻiliʻi." He hemahema kahua e kali ana.
Ke koho ʻana i kāu hoa hui Inconel 718: ʻEkolu Kūʻai ʻole
Ma mua o kou kau inoa ʻana i kahi PO, e nīnau i kēia mau nīnau—a koi i nā hōʻike:
- Hiki iā ʻoe ke hōʻike mai iaʻu i kāu mau lāʻau hoʻoponopono wela ʻekolu Inconel 718? ʻAʻole wale nā ʻanuʻu wela—akā, ka hoʻohui ʻana i ka lewa o ka umu ahi, ka nui o ka ramp, ka manawa hoʻoluʻu, a me ka helu hoʻoluʻu no AMS 2750E.
- Hana ʻoe i ka hōʻoia microstructure post-heat-treat? Hana mākou i ka SEM / EDS ma nā ʻāpana keʻa e hōʻoia i ka puʻunaue precipitate γ 'a me ka nele o ka δ-phase ma nā palena palaoa.
- He aha kāu manawa alakaʻi ʻino loa no kahi kauoha 15-hapa o kahi hale cylinder 220-mm-diameter-me nā palapala hōʻoia piha, nā hōʻike CMM, a me nā moʻolelo NDT? ʻO kā mākou pane he 28 lā kalena. ʻAʻole "4-6 wiki." ʻAʻole "pili." Mālama mākou iā ia i ka manawa maoli.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ʻaʻole ia e hoʻonoho iā ia iho he "factory Inconel 718" no ke kūʻai aku. Hoʻokahi mākou—no ka mea, i kēlā me kēia lā, hoʻoponopono kā mākou mau mīkini i nā meaʻai e pili ana i ka ʻikepili o ka mea hana manawa maoli, ʻike kā mākou metallurgists i ka heluhelu paʻakikī e kūʻē i nā hopena hoʻāʻo tensile, a hōʻailona kā mākou hui QA ma hope o ka hoʻāʻo ʻana e pili ana i nā pōʻai hana i kuhikuhi ʻia e ka mea kūʻai. ʻO ia ka ʻokoʻa ma waena o ka loaʻa ʻana a me ka hoʻonā.
Inā koi kāu papahana aʻe i nā ʻāpana Inconel 718 e ola ana i nā hola 10,000 ma 600°C, e hoʻopaʻa paʻa i ka sila ma 400 bar, a i ʻole e hoʻololi ʻole me ka haʻalulu ʻole ma 1,800 rpm-e hoʻomaka me kahi hoa nona ka hilinaʻi e noho nei i kā lākou umu ahi, ʻaʻole kā lākou tagline pūnaewele. ʻO ka pono ʻO Inconel 718 hale hana ʻaʻole hoʻohiki i ka hemolele. Hāʻawi ia i ka wānana-hoʻokahi i mālama ʻia me ka wela, ka mīkini pololei, hiki ke ʻike piha ʻia i ka manawa.
