ʻAʻole koho ʻia ka pale ʻana i ka corrosion kiʻekiʻe - ʻo ia ke kumu. Ke ʻālohilohi ka ʻulaʻula o ka ʻūhā, i ka wā e pōʻai ai nā hale turbine ma waena o 700°C a me ka cooldown wikiwiki, a i ʻole i ka wā e ʻai ai nā kahawai wai i loko o ka stainless maʻamau i 0.1 mm/makahiki, hoʻokahi wale nō papa o nā mea paʻa i ka laina: nickel-chromium superalloys like Inconel. Akā ʻaʻole hōʻoiaʻiʻo ʻia ka hana ʻana o ka papa hana maka wale nō. ʻO ka hilinaʻi honua maoli e pili ana i ke ʻano o ka ʻāpana Inconel hana ʻia - ʻaʻole wale ka mea i hana ʻia mai.
No ke aha i lawa ʻole ai ʻo "Inconel" - E pili ana i ka Microstructure Manaʻo
Ua ʻike mākou i nā papahana he nui i hāʻule ʻaʻole ma muli o ke koho ʻana i ka alloy, akā no ka hana ʻole ʻia. ʻO ka mea kūʻai aku ma North Sea oil & gas i hōʻike ʻia ʻo Inconel 625 no kahi hale hoʻomalu kaomi kiʻekiʻe - a laila loaʻa nā ʻāpana me ka kahe ʻana o ka palaoa inconsistent, micro-porosity kokoke i nā ʻāpana wela, a me ka pohā mua ma hope o 4,200 mau pōʻai wela. Ke kumu kumu? Ua hoʻohana ka mea hoʻolako i ka mīkini CNC maʻamau ma nā blanks as-cast me ka hoʻomaha ʻole ʻana i ke koʻikoʻi a i ʻole ka mana paʻa kuhikuhi. ʻAʻole ʻae ʻo Inconel i ka oxidation—akā inā ʻaʻole like kona ʻano dendritic, ʻoi aku ka maikaʻi o ka puʻu ʻana o ka carbide, a me kona koena koʻikoʻi ma lalo o 120 MPa.
Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., kēlā me kēia ʻāpana Inconel hoʻomaka me ka billet i hōʻoia ʻia e AMS a i ʻole hoʻopukapuka hoʻopukapuka mua—ʻaʻole loa e hoʻoheheʻe hou ʻia ka waiwai. Hōʻoia mākou i ke kemika ma o OES ma mua o ka hana ʻana, e ʻimi i kēlā me kēia ʻāpana mai ka log furnace a hiki i ka hōʻike CMM hope loa, a hoʻopili i ka hoʻoheheʻe annealing ma 1,095°C ±5°C me ka hoʻopaʻa ʻana i ka argon quenching. Pēlā mākou e paʻa ai i ka nui o ka palaoa i ka ASTM E112 Level 5–6 ma waena o nā geometries paʻakikī e like me nā hale pahu piston pump cylinder - nā ʻāpana e ʻike i ka puʻupuʻu 350 bar a me 650 ° C exhaust backflow.
Kahi e hāʻule ai ka mīkini maʻamau—a he aha ka hana
ʻOki ʻo Inconel 718 i ka 1/3 ka nui o ka hānai o 316 stainless. Hāʻule ke ola o ka mea hana ma 70% me kēlā me kēia 50°C e piʻi ma luna o 600°C ka wela o ka mea hana. E pane ana kekahi mau hale kūʻai ma ka hoʻolohi ʻana i nā mea a pau—a laila e noʻonoʻo no ke aha e piʻi ai ka manawa alakaʻi i 14 mau pule a piʻi ka ʻino o ka ʻili iā Ra 3.2 µm ma kahi o ka Ra 0.8.
Hana mākou i ʻekolu mau mea like ʻole:
- Nā kaʻina hana hoʻoheheʻe ʻia-machining: No nā kumu pahū a me nā kino kiwi, hoʻolei mākou i nā ʻano ʻupena kokoke me ka hoʻohana ʻana i nā ʻāpana pūpū seramika—e hoʻemi ana i ka manawa mīkini ma 65% ʻoiai e mālama ana i ka hoʻolike ʻana o ka palaoa ma nā ala hoʻouka.
- ʻO ka wili liʻiliʻi axis nui: Hoʻohana ʻia kā mākou Mazak INTEGREX i-200S i ka uku hoʻokaʻawale mea hana manawa maoli i ka wā wili hohonu o Inconel 601 nozzles—e mālama ana i ka hoʻololi ʻana o ka mānoanoa o ka pā ma lalo o ± 0.05 mm a hiki i ka 12:1 ka hohonu-a-ākea ratio.
- Hoʻopaʻa ma hope o ka hana: ʻO kēlā me kēia mīkini ʻāpana Inconel loaʻa i ka vibratory stress relief (VSR) ma 28 Hz no 45 mau minuke ma mua o ka nānā hope ʻana—e ʻoki ana i ka distortion i loko o nā hale pā lahilahi e 80% me ka ʻelemakule wela wale nō.
ʻAʻole kēia ka manaʻo. ʻO ia ke ʻano o kā mākou hāʻawi ʻana aku i 217 AMS 5387 cobalt-alloy 6 mau ʻāpana pahū i kahi OEM hydraulic German-me ka mālama ʻana o GD&T Zone i ± 0.015 mm ma nā datum koʻikoʻi 12, hana hou ʻole, a me ka hiki ke hiki ke hoʻoheheʻe i ka helu a me nā lāʻau pōʻai wela.
ʻO ke kumukūʻai huna o ke koho mea "maikaʻi maikaʻi".
ʻO kekahi poʻe ʻenekinia i hoʻopaʻa ʻole iā Inconel 600 no nā kaiapuni waiwai i ka sulfur. Hana ia—no ʻeono mahina. A laila hoʻomaka ka hoʻouka kaua intergranular ma weld HAZs. Hōʻike kekahi poʻe i ka Inconel 625 no ka lawelawe chloride—e nānā ʻole ana i kona hiki ke hoʻopōʻino ʻia ma lalo o ka pH 4.5 a me 80°C.
ʻAʻole mākou e hoʻohālikelike wale i nā ʻāpana i nā pakuhi wela. Hoʻopaʻa mākou i ka envelop holo holoʻokoʻa: ka wela kiʻekiʻe, ka nui o ka ramp thermal, ka wikiwiki o ka wai, ka pH, ka ppm chloride, a me ka ʻike hoʻouka mīkini. No nā pāpaʻi hoʻoheheʻe kemika ma waho, ua hoʻololi mākou i kahi mea kūʻai mai Inconel 625 i Inconel 686-hoʻohui ʻia 3% tungsten a me 1.6% niobium-e hoʻolōʻihi i ke ola lawelawe mai 9 a 34 mau mahina ma 120°C, 15,000 ppm Cl⁻ brine. No nā wili pahu winch kikowaena kiʻekiʻe ma luna o nā kaʻa ʻenekinia, hoʻohana mākou i nā pahu cobalt-nickel i hoʻohana ʻia ma T800 i hoʻohana ʻia ma o ka plasma transfer arc—e loaʻa ana i ka 62 HRC paʻakikī o ka ʻili me ka delamination ʻole ma hope o 2.1 miliona torque cycles.
ʻAʻole ka nānā ʻana i ka ʻikepili ʻikepili. ʻO ke kūkākūkā metallurgical - me kou kaiapuni, kou geometry, a me kāu mau ʻano hemahema.
Mai ke kaha kiʻi ʻana a hiki i ka hoʻouna ʻana: he aha ka mea e pono ai ka ʻāpana Inconel e pono ai
Hoʻomaka ka hilinaʻi ma mua o ka lele ʻana o ka chip mua. Nānā mākou i kēlā me kēia kelepona GD&T—ʻaʻole no ka hoʻokō ʻana, akā no ka hana ʻana. He kūlana hoʻomanawanui o Ø0.02 mm ma ka 300 mm flange? Hiki—akā me nā ʻili o ka datum honua a me ka hōʻoia ʻana i ka ea CMM. Haʻa mua mākou i kēlā mau mea. Hoʻāʻo pū mākou i ka huki ʻana ma nā diaphragms Inconel 718 hohonu e hoʻohana ana i ka hoʻoponopono kiʻi kiʻi kiʻi (DIC), e wānana ana i ka hoʻokaʻawale ʻana ma mua o ka ʻoki ʻia ʻana o ka mea hana.
ʻO kā mākou mea hoʻokō ISO e mālama i ke kaulahao piha: hōʻoiaʻiʻo ʻia nā mea waiwai, hoʻolei kālā no nā ala i loko o loko, 5-axis CNC no nā hiʻohiʻona o waho o ka hoʻomanawanui, ka wela wela, a me ka hoʻopau ʻana i ka ʻili - me ka electropolishing no nā hui pauma lāʻau lapaʻau a me nā uhi anodized paʻakikī no nā mīkini winch moana. ʻO ka nānā hope loa e pili ana i ka hoʻāʻo ʻana i ka dye penetrant no ka ASTM E1417, ka nānā ʻana i ke kani kani no ka ASTM E1961, a me ka hoʻāʻo ʻana i ke kaomi hana i 1.5x kaomi hana.
Inā makemake ʻoe i kahi ʻāpana Inconel e ola nei—ʻaʻole kūpono wale—e kelepona iā QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. pololei. Pane mākou i nā nīnau ʻenekinia i loko o 4 mau hola ʻoihana. Kaʻana mākou i nā palapala hōʻoia ma mua o ka hōʻoia ʻana i ke kauoha. A hoʻouna mākou i nā hōʻike dimensional me kēlā me kēia hoʻouna.
