Monel 400 machining factory — ʻoi aku ka nui o kēlā huaʻōlelo ma mua o ka hiki. Hōʻike ia i ka mākaukau no nā hana ʻoi aku ka paʻakikī: nā hale hydraulic kiʻekiʻe, nā ʻāpana wai kai, nā kino kinoea ʻawaʻawa, a me nā mea hana ma waho kahi e kū ai ka pale ʻana i ka corrosion me ka micron-level geometry control. Ua hana mākou i nā ʻāpana ʻo Monel 400 no nā mea kūʻai aku ma Houston, Rotterdam, a me Singapore - a i kēlā me kēia manawa, hiki mai ka pilikia like i ka wā mua: ʻo ka paʻakikī o nā mea hana i ka wā o ka ʻoki ʻana e hoʻomaka ai ka aahu ʻana i ka mea hana, ka haehae ʻana i ka ʻili, a me ka hoʻoheheʻe ʻana o ke ʻano inā ʻaʻole laka ʻia nā ʻāpana kaʻina ma mua o ka lele ʻana o ka chip mua.
No ke aha e koi ai ʻo Monel 400 i kahi ʻano hale kūʻai pololei
ʻAʻole kila kila ʻo Monel 400. He 67% nickel, 23% keleawe, me nā mea hoʻohui liʻiliʻi akā koʻikoʻi o ka hao, manganese, kalapona, a me ke silika. Aia kona ikaika tensile ma waena o 790–965 MPa — ʻoi aku ka kiʻekiʻe ma mua o 316 stainless — a ʻo kona conductivity wela he 23 W/m·K wale nō. ʻO ka hoʻokuʻu ʻana o ka wela haʻahaʻa, ʻo ia hoʻi, ʻo ka ʻoki ʻana i ka wela ka paʻa ʻana ma ke kikowaena mea hana. Holo wikiwiki nā hoʻokomo carbide maʻamau. Pono ke kahe o ka coolant i ke kaomi kiʻekiʻe, hoʻopaʻa ʻia, a me ka hoʻopau ʻole. E hāʻule ka nui o nā meaʻai i 30–40% versus Inconel 625. A me kekahi haʻalulu? Unuhi pololei ia i loko o nā hōʻailona kamaʻilio e hōʻino ana i ka pau ʻana o ka ʻili ma nā ʻili e hoʻopaʻa ʻia ai ʻole e lawe ana i nā puke pai.
Ua ʻike mākou i nā mea kūʻai aku e hoʻouna aku iā Monel 400 blanks i ʻekolu mau hale kūʻai like ʻole - e hoʻihoʻi wale i nā ʻāpana me ka pōʻai ID like ʻole, out-of-spec thread lead error, a i ʻole micro-cracking kokoke i nā kihi o loko. ʻO ke kumu kumu ʻaʻole ia i ka mākaukau hoʻohana. ʻAʻole i hoʻohālikelike ʻia ka hoʻolālā mea hana, ʻaʻole i hōʻoia ʻia i ka hoʻokumu ʻia ʻana o ka palaoa maka, a me ka nānā ʻole ʻana i ka wela. Pono ʻo Monel 400 machining i ka ʻike metallurgical i hoʻohui ʻia - ʻaʻole wale ka papahana CNC.
Pehea e hoʻomalu ai kahi hale hana mīkini ʻo Monel 400 i nā ʻano like ʻole
Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., mālama mākou iā Monel 400 ma ke ʻano he ʻōnaehana - ʻaʻole he papa waiwai. Hoʻomaka kēlā me kēia kauoha me ka pā a i ʻole ka pahu i hōʻoia ʻia e ka hui ASTM B127, i hōʻoia ʻia no ka nui o ka palaoa (ASTM E112), ka pale ʻana i ka corrosion intergranular (ASTM G28 Method A), a me ka kūlike o ka paʻakikī ma waena o ka ʻāpana. ʻAʻohe ʻokoʻa.
A laila mākou e palapala i nā ʻāpana hana o ka ʻāpana: pono nā maka sila Ra ≤0.4 μm; ʻO nā pahu hoʻoluhi paʻi e koi i ± 0.005 mm ka poepoe ma luna o 120 mm ka lōʻihi; ʻO nā awa i hoʻopaʻa ʻia e koi ana i ka hoʻopaʻa ʻana i ka milo piha piha me ka nānā ʻana iā Go/No-Go no ka ASME B1.20.1. Ma laila wale nō mākou e koho ai i nā mea paahana - nā ʻōnaʻi kiʻi kiʻi PCD maʻamau no nā lua hohonu, nā mea hoʻokomo wiper seramika no ka hoʻopau ʻana i nā hala, a me nā wili hope i mālama ʻia me ka cryogenically no ka wili ʻana o nā hubs impeller.
ʻO kā mākou mea hoʻokō ISO e holo ana i nā kikowaena machining multi-axis i hoʻolako ʻia me ka nānā ʻana i ka ukana spindle manawa maoli a me ka hoʻomalu ʻana i ka wela hoʻoluʻu hoʻopaʻa. Inā piʻi ka ikaika o ka mea hana ma mua o 12% o ka palena, hoʻomaha koke ka mīkini - ʻaʻohe kuhi, ʻaʻohe ʻōpala.
Kahi e lilo ai ka ʻike i nā hopena hiki ke hana hou ʻia
Pono kekahi mea kūʻai aku i 42 Monel 400 piston pump cylinder housings no nā ʻōnaehana hydraulic subsea. Hāʻawi kā lākou mea hoʻolako kumu i 17 mau ʻāpana - pau ka hoʻāʻo ʻana o ka helium leak ma 300 bar. Ke kumu kumu? ʻO ka micro-porosity mai ka hoʻolei ʻana i nā pilikia hānai, hoʻohui ʻia e ka ʻāwīwī ʻino i wehe ʻia nā lua o lalo. Ua hana hou mākou i ke kūkulu ʻana: hoʻomaka me nā blanks-cast blanks (AMS 5380 compliant), hoʻohui i ka hoʻāʻo ultrasonic ma mua o ka mīkini ʻana, hoʻohana i ka milling piʻi wale nō, a paʻa i nā ʻae ID hope ma Ø142.000+0.0100 mm me ka CMM traceability no kēlā me kēia hapa helu a me ka wela wela.
ʻO kekahi hihia: AMS 5387 cobalt alloy nozzles i hui pū ʻia me Monel 400 flange adapters. He ʻokoʻa ke ʻano o nā mea ʻelua ma lalo o ka paikikala wela. Ua holo mākou i nā hoʻohālikelike hoʻonui wela, hoʻoponopono i ka interference e like me ia, a hōʻoia i ke koʻikoʻi o ka hui me ka hoʻāʻo strain-gauge - ʻaʻole wale nā loiloi dimensional. ʻO ia ke ʻano e pale aku ai i nā hemahema o ke kahua ma 180°C a me 450 psi.
ʻAʻole kēia mau manaʻo loiloi. Hoʻopaʻa ʻia lākou i loko o kā mākou Hōʻike Hōʻoia Kaʻina Hana - loaʻa i nā mea kūʻai aku kūpono ma NDA.
He aha kāu e loaʻa ai mai kahi hale hana ʻenehana Monel 400 kūikawā
- Mea-mua hoʻolālā: ʻAʻole "holo wale ia ma ka VMC." Hōʻoia mākou i ka kemika, ke kuhikuhi ʻana i ka palaoa, a me ka mōʻaukala mālama wela ma mua o ka haʻi ʻana.
- ʻAʻohe koina hana hou huna: Loaʻa i ka nānā pono ʻana o ka ʻili ke ʻike keʻokeʻo (ma SEM/EDS) ma nā ʻaoʻao mīkini koʻikoʻi - no ka mea hiki i ka papa hana paʻakikī o Monel 400 ke hoʻomaka i nā māwae luhi ma lalo o ka hoʻouka ʻana.
- Hoʻokō GD&T piha: Wehewehe mākou i ke kūlana, ka ʻaoʻao, a me ka runout callouts ʻaʻole ma ke ʻano he hoʻomanawanui - akā ma ke ʻano he pono hana. ʻO ka hoʻomanawanui kūlana 0.02 mm ma kahi pōʻai bolt ʻaʻole ia e pili ana i kahi. E pili ana ia i ka hōʻoia ʻana i ka ikaika hoʻopaʻa ʻana ma luna o kahi interface gasket corrosive-fluid.
- Hoʻokomo ʻia ka traceability: Hoʻouna ʻia kēlā me kēia ʻāpana me ka palapala hōʻoia e hoʻopaʻa inoa ana i ka helu wela, ka hoʻoponopono polokalamu CNC, ka hōʻike hōʻike CMM, a me ka ID operator - ʻaʻole he peʻa.
ʻAʻole ʻo Monel 400 machining factory kahi ʻoihana kūʻai. He kūpaʻa ia i ka hoʻopaʻi metallurgical, ke kaʻina hana, a me ke kuleana ʻenehana. Ke hoʻohana nei kāu ʻāpana i nā kaiapuni waiwai nui o ka chloride, kiʻekiʻe, mālama ʻole - ʻaʻole koho ke kuʻikahi. ʻO ka pololei ke kumu. ʻO ka hilinaʻi ka mea hiki ke hāʻawi.
Inā makemake kāu papahana Monel 400 e hiki mai ana i ke kūpaʻa dimensional, ka pololei o ka ʻili, a me ka hiki ke hoʻopaʻa ʻia - e hoʻomaka me kahi hoa hana e mālama i nā ʻāpana nickel-copper e like me lākou: nā ʻōnaehana koʻikoʻi, ʻaʻole me ka metala.
